LIMA, Lígia et al. Evaluation of the psychometric properties of the Treatment Self-Regulation Questionnaire for chronic diseases. Rev. Enf. Ref. [online]. 2020, vol.serV, n.2, pp.e19069-e19069. ISSN 0874-0283.  https://doi.org/10.12707/RIV19069.

Background: The promotion of the management of the therapeutic regimen in people with chronic disease implies reliable and valid measures to assess motivation for treatment. Objective: To assess the psychometric properties of the Portuguese version of the Self-Regulation Questionnaire (SRQ) of the medication treatment in a sample of people with chronic disease. Methodology: A methodological study was conducted using the Confirmatory Factor Analysis (CFA). The sample was comprised of 189 people with chronic disease. Results: A three-factor solution of the SRQ showed poor fit to the model, thus a four-factor solution was suggested. The convergent validity was confirmed by associations between autonomous motivation, perceived competence and perception of a therapeutic environment that promotes autonomy, and adherence to medication. The reliability analysis showed satisfactory internal consistency values ranging between 0.56 and 0.90. Conclusion: The instrument shows good reliability and validity to assess self-regulation of the treatment regimen in people with chronic disease.
