Show moreScrupulosity, which is a subtype of obsessive-compulsive disorder (OCD) characterized by religious obsessions and compulsions, has been shown to be particularly debilitating. The current research concerning scrupulosity has mainly examined Western populations. There is a paucity of literature examining scrupulosity in Eastern populations, and no literature to date examining scrupulosity in a Chinese sample. In order to examine scrupulosity in China, a valid measure of scrupulosity is needed. The current study validated a Chinese version of the main measurement of scrupulosity, the Penn Inventory of Scrupulosity - Revised (PIOS-R), in a Chinese student sample. The PIOS-R was translated both linguistically and conceptually in consultation with the Chinese research team. New items were added for review and possible inclusion. 577 university students in China completed an online survey with study measures. This sample was randomly split into two groups, a primary group for the initial Confirmatory Factor Analysis (CFA) and a hold-out sample for follow up analyses. The initial CFA of the PIOS-R found that none of the three models identified met all criteria for adequate fit. A follow up Exploratory Factor Analysis (EFA) was conducted on the same group and found a two-factor model with updated items. This model was successfully cross-validated using a CFA in the hold-out sample. These analyses yielded the Penn Inventory of Scrupulosity – Chinese Version (PIOS-C). Preliminary reliability and validity were established with this revised measure. Having an accurate and valid measure of scrupulosity for the Chinese population will assist in characterizing scrupulosity in China and developing or refining appropriate treatments. Show less
