Adapting and validating psychometric properties of compact among Makerere University students

Abstract

A sequential mixed methods approach was utilized to translate, adapt and validate the Comprehensive Assessment of ACT (Acceptance and Commitment Therapy) proccesses (CompACT). Forward translation was done by a translation expert at the School of Languages department of Luganda, Makerere University, 9 mental health experts examined the translation, 8 laypersons also deliberated the translation and suggestions made by experts, 25 students responded to the adapted versions in a cognitive testing activity and finally, 500 students participated in the validation of the adapted versions. Adaptations produced a clear and relevant CompACT. Examination of the Factorial validity suggested that both versions had a 3-factor structure, with the Luganda version retaining 17 items while the other retained 20 items. For internal consistency reliability, the Luganda version had Cronbach’s alpha of .788 and the English version had Cronbach’s alpha of .783. Thus, both versions are considered reliable and valid to measure psychological flexibility and deduce the mental health state of the students and accordingly intervene. This study may also guide other tool validation projects.
