Abstract

Self-regulated health behavior is a social process. The Treatment Self-Regulation Questionnaire (TSRQ) concerns why people engage in healthy behavior, enter treatment for a medical condition, or try to change an unhealthy behavior. The TSRQ, which has been used in previous research to assess the many reasons for engaging in various health behaviors (Williams, Cox, Kouides, & Deci, 1999), taps into four different types of motivations proposed by Deci & Ryan (2000): identification, introjection, external regulation, and amotivation. Although theoretically derived, the factorial structure of the TSRQ was not formally validated. The purpose of the present research was twofold: 1) validate the theoretically proposed four factor structure with the use of Confirmatory Factor Analysis (CFA) and 2) assess the factorial equivalence (invariance) of the TSRQ across three health behaviors (diet, smoking, and exercise) with data collected from four different sites across the United States. A total of 2,731 participants completed the TSRQ. Results of CFA analyses revealed that the proposed 4-factor structure of the TSRQ was supported for all sites and all three health behaviors assessed. Confirmatory Fit Indices (CFI) ranged from .94 to .97, Goodness of Fit Indices (GFI) ranged from .88 to .94, and Root Mean Square of Approximation (RMSEA) ranged from .09 to .07. In addition, all items significantly loaded on their respective factor. Invariance analyses revealed that the factorial structure of the TSRQ was equivalent across all three health behaviors assessed. Results of the present research provide evidence for the validity and generalizability of the TSRQ. (PsycEXTRA Database Record (c) 2016 APA, all rights reserved)
