Self-regulation assessment: A validation study

Introduction. Self-regulation is planning and managing behavior appropriately and flexibly. It predicts well-being, health, and academic performance, among other things. The psycho-metric characterization of the Abbreviated Self-Regulation Questionnaire (CAR-abr.), which consists of 17 items, is presented. It is a versatile instrument extensively used in various coun-tries and professional contexts, such as education or clinical settings.
\nMethod. A content validation of the questionnaire was conducted to verify its linguistic and cultural adequacy, followed by an application to a convenience sample. 710 Colombian uni-versity students from 12 majors, aged 18 to 33 years (M = 20.3, SD = 4.3), 31.5% men partic-ipated.
\nResults. The results indicate a good fit of the items to the Rasch model, adequate functioning of the Likert scale, and evidence of construct validity, although the questionnaire would bene-fit from including items of greater difficulty. The reliability was .84 for individuals and .98 for items. The self-regulation score correlated positively with flourishing (.416**, p<.01) and mental health (.372**, p<.01), and negatively with bad habits (-.343**, p<.01).
\nDiscussion and conclusions. The test can be used in various measurement and evaluation contexts. The results allow for establishing a level of self-regulation with sufficient reliability and evidence of validity. The possible uses and limitations of CAR-abr. for psychological measurement and evaluation are discussed.
