Abstract

The aim of this study was to validate the Polish adaptation of the Treatment Self-Regulation Questionnaire, which measures the degree of self-determination in risk behaviour changes. The study comprised 219 patients, beginning to undergo treatment. The Global Motivation Scale was used to test a convergent validity. The confirmatory factor analysis did not support the theoretical four-factor model, thus an exploratory analysis was conducted to determine an optimal model across risk behaviours. The adopted two-factor model matched original TSRQ subscales: autonomous motivation and external regulation. The internal consistency of factors ranging from.78 to.89. Structural equation modeling revealed the impact of global motivation on contextual motivation, limited to the equivalent type of regulation. The action aimed at supporting patient’s autonomy should consider the particular behaviour and the global motivation as a resource in disease.
