Show moreThe Theory of Planned Behavior (TPB) has been successfully used to link attitudes, subjective norms, and perceived behavioral control to the enactment of various behaviors in numerous situations; however, the TPB in not frequently used in organizational settings. Similarly, contextual factors may represent important moderating and mediating effects that have not been fully explored in prior TPB research. The current study employs the TPB in a healthcare setting to assess the use of Outcome Measures (OMs) by practicing clinicians. Two contextual mediators and a one contextual moderator were added to the standard TPB framework in an attempt to better explain the enactment of discretionary workplace behavior. Results suggest that TPB components are related to the discretionary use of Outcome Measures in clinical practice; however, results also suggest that hypothesized relationships between TPB factors may diverge significantly from those proposed in the original theory. Implications, limitations, and future directions are also discussed. Ph.D. in Psychology, July 2014 Show less
