Show moreObstructive sleep apnea (OSA) is characterized by loud snoring and repeated episodes of obstruction in the upper airway during sleep that cause partial or total stop in the airflow, often resulting in short, disruptive sleep. Sleep disruption as a result of OSA has been shown to result in reduced cognitive functioning and disordered eating behaviors, however, few studies to date have sought to determine whether OSA is associated with disordered eating behaviors. Bariatric patients are asked to restrict their food intake prior to surgery; however, restraint theory suggests that the eating behavior of those intending to restrict their intake can be disinhibited by a variety of conditions, which cause the restrained eater to engage in disinhibited and overeating behaviors. Depression has also demonstrated an association with disordered eating behaviors and cognitive dysfunction. Affect regulation theory is often cited as a possible explanation for this association, with the desire to avoid unpleasant affective states resulting in disordered eating behaviors. A sample of 93 bariatric surgery candidates were recruited from an academic medical center in a large metropolitan city to participate in the current study. Participants were recruited during their routine pre-surgical assessment for bariatric surgery and completed measures of disordered eating and depression. Both body mass index and diagnosis of OSA were obtained from patient medical chart. It was hypothesized that the presence of OSA would be related to higher levels of disordered eating behaviors, including disinhibited eating, frequency of loss of control and frequency of binge eating. Additionally, it was hypothesized that cognitive dietary restraint would moderate the association between OSA and disordered eating in bariatric patients, such that the greater the intent to strictly control food intake (i.e., greater cognitive dietary restraint), the more strongly sleep disturbance will be associated with disordered eating. Finally, it was hypothesized that depression would mediate the association between OSA and disordered eating in bariatric patients, such that depressive symptomatology accounts for the relation between OSA and disordered eating behaviors. Results indicated that the presence of OSA was not related to higher levels of disordered eating behaviors, nor did depression mediate the association between OSA and the disordered eating outcomes. Two of the moderation models were significant, including the disinhibited eating model and the frequency of loss of control over eating model. Although bariatric patients are encouraged to restrict their food intake, findings suggested that restraint does not appear to function as intended in reducing disinhibited eating behaviors in individuals with OSA. The findings for the loss of control model supported restraint theory and suggested that those with OSA who also endorse high restraint are at increased risk for experiencing loss of control over eating, whereas those who do not have cognitive dysfunction associated with OSA may or may not exhibit the same association. The current study highlights the impact of restraint on bariatric patients’ disordered eating behaviors, suggesting that restraint theory may not be entirely applicable to bariatric populations and may depend on the disordered eating behavior being examined. The current study also points to numerous gaps in the current literature and provides future directions for research on OSA and disordered eating in bariatric populations.

Show moreNonverbal Learning Disability (NLD) has been the focus of four decades of neuropsychological research. However, it has yet to be included as a diagnostic category in the Diagnostic and Statistical Manual of Mental Disorders (i.e., currently in its fifth edition, DSM-5, American Psychiatric Association, 2013). Many of the characteristics associated with Nonverbal Learning Disorder (NLD) are similar to those found in other more established disorders such as Attention-Deficit/Hyperactivity Disorder (ADHD), Specific Learning Disorders (SLD), and Autism Spectrum Disorder (ASD). Recent research in neuropsychology and other fields has contributed to a greater understanding of the cognitive profiles of NLD, ADHD, and Reading Disorder (RD). However, the neurological underpinnings of deficits in executive functioning specific to NLD versus ADHD and RD have yet to be fully elucidated. Ongoing research has failed to distinguish NLD from other childhood disorders, including ADHD, based on specific structural or functional neurological deficits. The current study examined the specificity of deficits in executive functioning in youth with nonverbal learning disability, attention deficit hyperactivity disorder and reading disorder. In addition, the study examined the degree to which the Rey Complex Figure Test subscales and Processing Speed Index (PSI) and Working Memory Index (WMI) scores (WISC-IV or WISC-III) could discriminate between the NLD group from ADHD and RD groups. Data for the present study were collected from a population served by the Pediatric Neuropsychological Service at The University of Chicago Medicine. Children who had been referred for neuropsychological assessment and whose comprehensive battery included a WISC measure (WISC-III or WISC-IV) and RCFT measurements were included. All data were archival, i.e., gleaned from the Service database; data from 202 participants was retrieved, including youth who underwent neuropsychological evaluation between 2003 and 2016. The present study hypothesized differences between NLD, ADHD, and RD diagnostic groups on visuo-spatial planning/organization, visuo-spatial working memory, long-term visuo-spatial recall, visuo-spatial recognition, verbal working memory, and processing speed. In summary, of the six executive function domains examined, two domains showed significant underperformance for the NLD group, two domains showed a non-significant trend of underperformance for the NLD group and two domains did not show significant differences between diagnostic groups.

Show moreThere is a dearth of quantitative research examining the public stigma of Tourette syndrome (TS), and no known studies assessing public perceptions of difference (how similar they are), disdain (how bad they are), and blame (how responsible they are) toward individuals with TS. The current study sought to understand the public stigma of TS as a visible and unconcealable condition. An internet sample of 450 adults were recruited through MTurk. Participants read four brief vignettes, each describing an adolescent with TS, obsessive-compulsive disorder (OCD), autism spectrum disorder (ASD), or a history of juvenile detention. Results showed TS to be associated with neutral or negative public perceptions across stigma facets. When compared to OCD and ASD, vignettes describing TS were viewed with similar difference, disdain, and blame. TS was least familiar to participants. Findings highlight differences in stigma for concealable versus visible stigmatized conditions which has implications for future research and anti-stigma interventions.

Title: Examining Racial Differences in Body Dissatisfaction and Disordered Eating Following Media Exposure of a Curvaceous Body Ideal

Show morePrevious research has found that internalization of a thin body ideal contributes to negative cognitive and behavioral symptoms, such as body dissatisfaction and disordered eating. However, studies supporting a sociocultural model have typically included mostly White samples. Research suggests that there may be racial differences in body dissatisfaction and disordered eating among Black and White women, specifically that Black women may be protected from body dissatisfaction via the buffering hypothesis. However, studies have found that differences in body dissatisfaction between Black and White women are smaller than previously thought. Additionally, Black women do not feel represented in the mainstream media on the basis of their physical appearance and ascribed ideals when exposed to thin ideals. Research is needed to examine the impact of other ideals (e.g., the curvaceous body ideal) on body dissatisfaction, as well as body dissatisfaction for Black women in Western culture. The present study used an experimental design to examine differences in body dissatisfaction and disordered eating behaviors in a community sample of Black and White self-identified women before and after exposure to a thin or curvaceous body ideal. Participants were randomized to a thin ideal or curvaceous ideal condition. All participants completed a demographic questionnaire, baseline measures of body dissatisfaction and disordered eating and Visual Analog Scales before and after viewing thin or curvaceous images. Findings indicated no racial differences in baseline body dissatisfaction and disordered eating. Additionally, associations between baseline body dissatisfaction and disordered eating were significant and align with previous research, but an effect of condition was found on body satisfaction change scores. No statistically significant interaction was found between race and body ideal condition for body dissatisfaction change scores. Finally, change scores of body dissatisfaction measures were not statistically different from pre- to post-exposure of either thin or curvy body ideal conditions. Findings have significant implications for the buffering hypothesis and add to studies that have found small racial differences in body dissatisfaction. Present findings also have implications for assessment and treatment in overall eating pathology as seen by the Sociocultural Model in Black women.

Show moreThe literature on executive functioning (EF) and academic performance has focused on early academic performance in young children (Best et al., 2011). Few studies have assessed the relation between EF abilities and academics in adolescents, which is particularly important because the demand on EF skills greatly increases in middle and high school (Best et al., 2011). Environmental factors, including completing multiple assignments, managing increased independent work, and changing classes, exacerbate the EF burden and reduce cognitive resources (Langberg et al., 2013; Samuels et al., 2016). Academic tasks also become more complex during middle and high school, for example, requiring solving algebraic problems, reading comprehension, and expository writing (Bull & Scerif, 2001; Sesma et al., 2009). Thus, complex academic tasks in adolescence likely require a higher demand on EF abilities compared to academic tasks in early childhood. The extant literature also has several limitations, such as focusing on only a couple of EF or academic domains and using parent- or teacher-report ratings rather than performance measures. Therefore, the aim of this study was to examine the relation between four domains of EF (i.e., working memory, inhibition, shifting, and planning) and three areas of academic performance (i.e., reading, writing, math) in a sample (N = 87) of clinically-referred middle and high school students. Contrary to expectation, results of hierarchical multiple regression analyses revealed that the measures of EF did not contribute significant additional variance to scores in reading and writing performance after controlling for IQ. It is notable that the EF variables did contribute a significant amount of additional variance to math scores after controlling for IQ and diagnosis. However, only working memory was significantly associated with math performance. This finding suggests that strategies designed to enhance working memory may be effective in improving math performance in students who are underperforming.

Show morePakistani Americans face bi-directional cultural influences related to their heritage culture and the mainstream culture of the host. The present study examined the impact of culture on the relationship between public stigma and care-seeking attitudes. A sample of 158 Pakistani Americans was collected using MTurk. Hierarchical regression was conducted to examine the moderating effect of heritage acculturation and mainstream acculturation on the relationship between public stigma and care-seeking. Multiple regression analysis predicting care-seeking from public stigma, heritage acculturation, and mainstream acculturation did not yield a statistically significant model. Hierarchical regression analyses examining the moderating effect of heritage acculturation and mainstream acculturation were non-significant. Acculturation had no notable impact on stigma and care-seeking. This study was unable to demonstrate significant results. Future considerations should include inter-generational differences, other forms of stigma that may play a crucial role, and inclusion of different measures to determine if there are other scales better suited for the target population.

Show moreResearch on eating disorder (ED) symptomatology in sexual minority (SM) women is limited and has demonstrated inconsistent findings with respect to how they differ from heterosexual women. Further, many studies combine SM women into one group, potentially masking important sub-group differences. Existing data appears to suggest that SM women may be at similar or increased risk for certain types of disordered eating behaviors and present with body image concerns that may differ from heteronormative female body ideals. However, it is unclear how weight and shape control behaviors differ across sexual orientations in women seeking treatment for EDs, and if there are differences in treatment outcomes. The present study used analyses of variance and covariance to test 1) group differences in frequency and severity of ED symptomatology and 2) differences in group by time interaction effects as an indicator of treatment outcomes in a sample of 3,120 adult women of diverse sexual orientations who presented for ED treatment between 2015 and 2018. Participants identified their sexuality as heterosexual, lesbian, bisexual, or other/unsure. Results indicated notable group differences in ED symptoms upon admission to treatment. Bisexual women, in particular, presented to treatment at younger ages, with higher BMIs, and more severe illnesses than heterosexual women. Further, results from the present study suggest that despite such differences, women across sexual orientation groups achieved similar treatment outcomes. These findings underscore the importance of subgroup analyses of ED symptoms in SM women and have both clinical and research implications related to ED psychopathology in this population.

Show morePrevious research has linked sleep disturbances with disordered eating. Studies have also shown that one night of partial sleep deprivation causes increases in food intake and appetite disturbances. However, the effects of sleep deprivation on disordered eating are unclear as research has yet to examine the effects of one night of partial sleep deprivation (≤ 4 hours of sleep) on disordered eating in a representative adult female sample. Adult, female participants (N=40) completed eligibility and baseline measures reporting medical conditions, eating disorder symptoms, sleep disturbances, depressed mood, and anxiety symptoms. Participants were randomized to either the sleep-deprived condition (~50% of their average sleep duration) or the habitual-sleep condition (~100% of their average sleep duration). The morning after the sleep condition, participants completed self-report appetite and disordered eating measures before and after consuming a test meal and later that evening. The following statistical analyses, adjusted for multiple comparisons (p<0.002), found no significant group differences: independent samples t-tests (outcome: pre-meal appetite, disordered eating, and test-meal consumption), multivariate analyses of variance (MANOVAs; outcome: pre- and post-meal area under the curve disordered eating and appetite), repeated measures ANOVAs (time X group; outcome: pre- and post-meal appetite and disordered eating), analyses of covariance (ANCOVAs; controlling for pre-meal ratings; outcome: disordered eating at follow-up), and chi-square tests (outcome: follow-up appetite and disordered eating). Despite finding no support for the effect of sleep deprivation on disordered eating, this study extends previous research as a novel study using the experimental manipulation of sleep deprivation to examine its effects on disordered eating.

Show moreDisruptive behavior disorders are among the most prevalent psychological disorders in preschoolers. There are evidence-based treatments for these disorders, but clinically significant behavior problems persist in approximately one-fourth to one-third of children after treatment. These treatments consist of behavioral parenting interventions and are not designed to directly address children’s affective dysregulation, which is a core component of behavior problems. To address this limitation, a manualized intervention was developed to treat disruptive behavior in preschool-age children by specifically targeting their emotion regulation abilities as the mechanism of change by coaching the caregiver to scaffold the child’s emotion regulation strategy use. The purpose of the present study was to further the development of this intervention by obtaining feedback from key stakeholders (i.e., caregivers and therapists) on the intervention’s focus, content, and procedures. Obtaining this feedback is an essential component of developing a novel psychosocial intervention. A qualitative thematic analysis of in-depth focus group discussions was conducted. Data were organized into the following broad themes: Intervention approach (support for targeting emotion regulation but ensuring the approach is an appropriate fit and considering the important role of behavioral strategies; additional focus on facilitating a positive caregiver-child relationship; developing some independent regulation skills in the child), Intervention structure and session content (making the intervention structure more flexible or modular; retaining the main intervention components with modifications to enhance acceptability, relevance, and developmental appropriateness), The caregiver’s role (the caregiver’s role is of primary importance and should be active throughout all sessions; ensuring adequate caregiver preparation and skill development; additional primary focus on facilitating the caregiver’s own emotion regulation; attention to the caregiver’s own therapeutic needs), Individualized approach (individualizing the content and timing of all sessions to account for individual needs), Generalizability (ensuring generalization of skills to home and other settings through effective at-home practice and including other primary caregivers and family members in sessions), and Learning and skill development (considering individual differences in how children and caregivers learn and modifying activities accordingly). These themes and stakeholders’ specific feedback will guide revisions to the intervention manual prior to pilot testing and further examination of efficacy and effectiveness.

Show moreResearch has been limited regarding the stigma experienced by parents of children with mental health challenges. It is commonly understood that stigma effects people with lived-experience (e.g., a child with mental health challenges), however, stigma has been noted to have a wide scope, which extends to family members as well. Parents of children with mental health challenges have been found to endorse aspects of self-stigma, specifically regarding public stereotypes of blame and feelings of incompetence. Vicarious stigma is a fairly new area of research, which describes the sad and/or angry response a parent may experience when witnessing their child being stigmatized. The purpose of this study is to examine emotional and behavioral outcomes related to specific types of stigma experienced by parents of children with mental health challenges. Archival data from a larger study of adult participants (N=50), who identified as having a child (age 3-10 years old) with mental health challenges, completed measures examining self-stigma, vicarious stigma, stress, depression, quality of life, disclosure, secrecy coping, and help-seeking. A novel measurement for vicarious stigma was introduced and examined in this study. Results found higher levels of self-stigma and dimensions of vicarious stigma were associated with higher levels of depression as well as diminished quality of life. Higher levels of self-stigma were also associated with lower perceived benefits of disclosing and greater levels of secrecy coping. These findings highlight the importance of further examining the role of stigma for parents of children with mental health challenges.

Show moreObjective: Immigrants from India face unique obstacles, including migration related factors and cultural pressures, that may contribute to underutilization of mental health treatment services. The present thesis examined paths between mental health stigma and care-seeking in a sample of first-generation Indian immigrants, with a specific emphasis on the influences of acculturation and parental autonomy support. Method: A sample of 201 first-generation immigrants from India was ascertained using MTurk. Path analysis was conducted to examine the relationships between public stigma of mental illness, disclosure, mental health care-seeking, parental autonomy support, and bi-directional acculturation. Results: Final model was supported by good fit indicators. Greater public stigma was associated with reduced care-seeking, but greater disclosure was associated with increased care-seeking. Interestingly, parental autonomy support, mainstream acculturation, and heritage acculturation facilitated disclosure but had no discernible impact on public stigma. Conclusions: In contrast to traditional anti-stigma strategies that focus on reducing public stigma, present results suggest that it may be more beneficial to facilitate care-seeking by targeting disclosure of status. In turn, disclosure may be promoted by facilitating autonomy supportive social networks and bi-directional acculturation.

Show moreSome subgroups of military veterans, including those with marginalized identities, may be especially vulnerable to poor health. This hypothesis is supported by the Minority Stress Theory framework, which posits that disparities in health can be attributed to the stress that minority individuals experience as a result of discrimination, prejudice, and oppression (Meyer, 1995; Meyer, 2003). A specific, potentially marginalized group of veterans that is under-explored regarding health is transgender veterans. Using data from the 2019 U.S. Behavioral Risk Factor Surveillance System (BRFSS), the current study hypothesized that transgender U.S. military veterans will report worse health than cisgender U.S. military veterans. Using case control matching, groups of transgender veterans (n = 124) and cisgender veterans (n = 104) were compared on several population-relevant health outcome measures. Chi-square tests of independence were conducted to test for significant differences between transgender and cisgender military veterans on the likelihood of experiencing certain health conditions, engaging in certain health behaviors, and utilizing health care services. Independent samples t-tests were used to test continuous health outcomes, such as self-reported mental health, physical health, and access to health care services. Gender identity was significantly associated with only one health outcome variable, with transgender veterans being more likely than cisgender veterans to have received a formal depression diagnosis (p = .01, phi = .17). No significant differences emerged between transgender and cisgender veterans on continuous health outcome variables. This suggests that previous literature on health disparities between transgender and cisgender individuals may not be generalizable to transgender veterans.

Show moreTransgender individuals often experience poor health outcomes related to a lack of provider knowledge and comfort around transgender issues. Ally identity development and cultural humility theories have been used to develop interventions shown to improve attitudes, knowledge, and skills related to being an ally to the transgender community. Additionally, healthcare providers have reported a desire for online tools related to transgender healthcare, and online interventions can be more cost effective than traditional in-person trainings. The current study developed an hour-long online intervention composed of six activities aiming to increase attitudes, knowledge, skills, and identification as an ally to the transgender community. Tests were conducted to assess whether these domains increased significantly from baseline to post in the intervention condition compared to the control condition and whether the increase was maintained at 2-week follow up. The sample included cisgender (i.e., male or female) students studying a subject related to healthcare recruited online through Prolific (N = 78). Results indicated that knowledge and skills increased significantly from baseline to post in the intervention condition compared to the control condition, and increases were maintained at 2-week follow up. However, this was not the case for attitudes and identity. These findings largely replicate existing research on knowledge about transgender individuals and provide new insights into skills, attitudes, and identity related to transgender allyship. Findings can inform future research on transgender allyship intervention design and allyship theory as well as support improvements in clinical practice and policy related to transgender healthcare services.

Show moreMajor Depressive Disorder (MDD) is one of the most prevalent mental health disorders, with a lifetime prevalence rate of 13-16% and 12-month prevalence rates of 5-7%. It has long been established that the rates of MDD in females is two to three times that of males. Previous research has examined sex differences in the occurrence and severity of MDD symptoms, primarily indicating greater severity of appetite increase and weight gain in females compared to males. The majority of previous research has been conducted assuming the latent factor model that MDD accounts for the symptoms of depression, and sex operates as a mediator or moderator between the latent variable and MDD, or between MDD and its symptoms. The present study used network analysis to examine whether there are sex differences in the relations between symptoms of depression, which might be an important factor for understanding sex differences in prevalence rates of MDD. The present study compared networks of DSM MDD symptoms between currently depressed females and males, and separate networks that also included other symptoms commonly associated with depression (e.g., anxiety, anger). Sex differences were examined using jointly estimated networks, and a Network Comparison Test (NCT) for the independently estimated networks. Results indicated no sex differences in depression symptom networks. These results indicate that depressive symptom networks, or the relations between symptoms are not an important factor for understanding the disparity in sex differences in MDD prevalence rates. Interestingly, non-DSM symptoms were among the strongest and most important symptoms within the network, suggesting future research and diagnostic criteria should consider inclusion of non-DSM symptoms associated with MDD.

Show moreChronic loneliness is a risk factor associated with adverse psychological, physical, and academic outcomes. Converging evidence suggests that young children experience and can reliably report on their own loneliness. Due to the significant negative sequalae associated with childhood loneliness, it is critically important to examine risk factors for child loneliness. The aims of this study were two-fold: (a) to examine if temperament (i.e., negative affect, effortful control, and inhibitory control) and attachment security assessed at 4 years of age predict loneliness at age 6; and (b) to determine if social competence at age 5 mediates the relation between temperament and attachment security at age 4 and loneliness at age 6. Participants included a diverse sample of 796 4-year old children, about half of whom were male. At age 4, temperament was assessed with the Rothbart Child Behavior Questionnaire and three inhibitory control tasks, and attachment security was assessed with the Attachment Q-Sort. At age 5, the Social Skills Rating Scale was used to assess social competence, and, at age 6, loneliness was assessed with the Loneliness and Social Dissatisfaction Questionnaire. Results of hierarchical regression analyses indicated that lower levels of effortful control and inhibitory control at age 4 significantly predicted higher levels of loneliness at age 6. Also, lower levels of negative affect and higher levels of effortful control and attachment security at age 4 significantly predicted higher levels of social competence at age 5. However, social competence at age 5 did not predict loneliness at age 6. There was no evidence that social competence at age 5 mediated the relation between age 4 temperament, attachment security and age 6 loneliness. These findings reveal that early self-regulation is associated with later child-reported loneliness and that intervention for children who struggle with cognitive regulation may be effective in decreasing risk for later loneliness.

Show moreThis study investigated the associations between obsessive compulsive disorder symptoms (OCS) and tobacco use and tobacco dependence in a large community sample of adolescents. Specifically, transdiagnostic emotional vulnerability factors (i.e., anhedonia, distress tolerance and anxiety sensitivity) were explored as potential mediators of the relation between OCS and tobacco use/dependence. Weighted logistic regression models found that OCS was significantly positively associated with likelihood of tobacco use in the past six months (when suppressor variables were excluded). Similarly, zero-inflated negative binomial regression models found a significant positive relation between OCS and tobacco dependence (when suppressor variables were excluded). There was no significant weighted indirect effect via anhedonia for the OCS-Tobacco Use association, which suggests that anhedonia was not a significant mediator in this case. However, the indirect effect via anhedonia for the OCS-Tobacco Dependence association was significant at the p < .05 level, but not the adjusted p < .001 threshold (when suppressor variables were removed). The weighted indirect effect via distress tolerance for the OCS-Tobacco Use association was significant at the p < .05 level, but not the p < .001 threshold (when suppressor variables were removed). There was no significant indirect effect via distress tolerance for the OCS-Tobacco Dependence association. There was a significant weighted indirect effect via anxiety sensitivity for the OCS-Tobacco Use association (when suppressor variables were removed). There were no significant indirect effects via anxiety sensitivity for the OCS-Tobacco Dependence association. When overlapping variance was accounted for by including all three mediators simultaneously, anhedonia was still not a significant mediator of the OCS-Tobacco Use association; there were still significant indirect effects via distress tolerance and anxiety sensitivity, under specific model parameters. Our results also revealed that while Asian adolescents demonstrated lower likelihood of tobacco use compared to those who were Hispanic/Latinae, Asian youth demonstrated more severe tobacco dependence symptoms.

Show moreHoarding disorder (HD) is characterized by significant difficulty discarding items, resulting in an accumulation of clutter. HD is a public health concern and is associated with treatment ambivalence (e.g., refusal to initiate treatment, dropout, and limited treatment compliance). While low insight and motivation may account for some of the treatment ambivalence, it also could be due to a number of other factors related to how HD is being perceived by others, such as stigma. Yet, there is very little research on the relationship between stigma and hoarding, and what these studies have shown is that HD is judged negatively by the general population (i.e., public stigma) in a variety of ways. However, despite these initial findings, there are no in-depth studies examining stigma of HD from the perspective of those with lived experience. Further, previous research of stigma and HD utilized stigma measures that were significantly modified from their original intent to measure severe mental illness, and it is possible that general measures of stigma may not capture the specific features of HD or public perceptions of HD. The present study is a qualitative analysis to investigate stigma pertinent to HD.

Show moreIndividuals who acquire a spinal cord injury (SCI) during their pediatric years are unique from individuals who acquire an SCI during adulthood due to the heightened risks for developing secondary health conditions and chronic pain. These concerns may significantly impede developmental milestones and experiences, such as social participation, that may decrease life satisfaction. Thus, research on pain characteristics (e.g., frequency of pain, duration of pain, level of current pain, and level of general pain) alongside the role of emotional support and social participation on life satisfaction in adults with pediatric-onset SCI is needed. This study sample consisted of 205 individuals with pediatric-onset SCI who were former patients at pediatric hospitals in three metropolitan cities. Participants were individuals who were 19 years of age or older at the time of the interview, with the age of injury at 18 years or prior. Associations between demographic, pain, and injury characteristics, emotional support, social participation, and life satisfaction were assessed via bivariate Pearson correlations and a 3-block hierarchical multiple linear regression with LS as the primary outcome. Although pain characteristics and emotional support were not associated with life satisfaction among adults who sustained a pediatric-onset SCI, social participation was positively associated with life satisfaction. These findings suggest that clinicians should evaluate various pain characteristics and highlight the role of social participation when treating individuals with SCI.

Show moreThe present study examines sorting techniques and deficits among individuals with hoarding disorder (n = 34) compared to age- and gender-matched adults (n = 35) in the general population. Performance was compared on the Booklet Category Test (BCT), selected other neuropsychological measures, and an ecologically valid sorting task designed for the study to model the Delis-Kaplan Executive Function System (D-KEFS) Sorting subtest but with common household objects as stimuli. Contrary to predictions, individuals with hoarding disorder did not perform significantly worse than controls on the BCT or the sorting task designed for the present study. Also contrary to predictions, the hoarding group performed significantly better when initiating their own sorts of the objects than when tasked with naming categories grouped by the researcher. These findings are discussed as well as exploratory analyses suggesting participants with hoarding put forth more mental effort sorting the household objects (shoes and mail). They provided significantly more individual responses on the task with significantly more description errors. IQ and performance on other selected neuropsychological measures were not significantly different between groups. These findings provide preliminary evidence there may be specific types of real-life sorting difficulties associated with hoarding disorder that are subtle and beyond what existing neuropsychological tests can measure. Given that current CBT treatments for hoarding presuppose a certain level of competency in sorting (e.g., recognizing and naming different categories of household items to complete a personal organizing plan), it is important to clarify potential sorting and categorization deficits in this group as one possible avenue to help improve treatment response among individuals struggling with hoarding disorder.

Show moreBody dissatisfaction is associated with marked distress and often precipitates disordered eating symptomology. Body dissatisfaction in male athletes is an important area to explore, as research in this field often focuses on eating disorders in female athletes. The current body of literature regarding male college athletes suggests that they experience pressures associated with both societal muscular ideals and sport performance. While there is a clear association between drive for muscularity and body dissatisfaction in college male athletes, no study to date has evaluated the efficacy of a body dissatisfaction intervention for this population. Therefore, the present study sought to investigate the efficacy and feasibility of a pilot intervention program that targeted body dissatisfaction in male college athletes. Participants were randomized into an adapted version of the Female Athlete Body Project (i.e., the Male Athlete Body Project) or an assessment-only control condition. A total of 79 male college athletes (39 in treatment condition) completed this study for a retention rate of 84.9%. Participants in the experimental group attended three 80-minute group sessions once a week for three weeks. All participants completed measures of body dissatisfaction, internalization of the body ideal, drive for muscularity, negative affect, and sport confidence at three time points: baseline, post-treatment (three weeks after baseline for the control condition), and one-month follow-up. Hierarchical Linear Modeling was used to assess differences between conditions across time. Participation in the MABP improved men’s satisfaction with specific body parts, drive for muscularity, and body-ideal internalization at post-treatment. Men in the MABP also reported improvements in appearance evaluation and overweight preoccupation at post-treatment and one-month follow-up, and in negative affect at one-month follow-up only. Improvements in drive for muscularity were retained at one-month follow-up. This study provides preliminary evidence for the feasibility and efficacy of the Male Athlete Body Project.
