The aim of this study was to validate the Polish adaptation of the Treatment Self-Regulation Questionnaire (TSRQ; Ryan, Conell, 1989), which measures the degree of self-determination in risk behaviour changes (diet, exercise and smoking). The study comprised 219 patients (101 after acute coronary syndrome and 118 with type 2 diabetes), beginning to undergo treatment. The Global Motivation Scale was used to test a convergent validity. The confi rmatory factor analysis (CFA) 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 (it did not contain the items from the introjected regulation and amotivation subscales). The internal consistency of factors (Cronbach’s α) 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.
The aim of the study was to confi rm the mediation effects of the task-specifi c self-effi cacy on the relationship between the general self-effi cacy and intention and planning considering treatment. The study comprised 265 subjects, of which 165 were post-mastectomy women and 100 patients hospitalized due to acute coronary syndrome (ACS). The variables were assessed using the Generalized Self-Effi cacy Scale (GSES) and tools developed to examine the context of treatment. The data were analyzed using the bootstrapping procedure. The results confi rmed the indirect effects of task-specifi c self-effi cacy, both in women making a decision to undergo breast reconstruction, and in patients after ACS formulating intention to change risk behaviours. As smoking was considered to be a moderator in the post-ACS group, the obtained associations were observed only among the patients declaring quitting smoking. In view of the fact that taskspecifi c self-effi cacy is susceptible to context (e.g. it may depend on quitting smoking), it is useful to assess it in order to increase treatment effectiveness.
