The Appraisal of self-care agency scale - revised (ASAS-R): reliability and validity among Portuguese medical students
| Summary: | Self-care agency plays an important role in the individual's physical and mental health. As med-ical students deal with distressful events and particularities of their education, self-care agency can be a protective factor for their mental health. This study aims to validate the Portuguese version of the Appraisal of Self-care Agency Scale-Revised (ASAS-R) in Portuguese medical stu-dents. A cross-sectional, quantitative, and analytical online study was conducted. Exploratory factor analysis (EFA) was performed to test the internal structure of the ASAS-R. Correlations with the SHS (Subjective Happiness Scale), SWLS (Satisfaction with Life Scale), and MHI (Mental Health Inventory) were calculated using Pearson's coefficient so as to test convergent validity. Internal consistency was evaluated using inter-item correlation, corrected item-total correlation, and Cronbach's alpha. The total sample included 781 individuals. EFA yielded a 3-factor solu-tion accounting for 53.9% of the explained variance. Pearson's coefficients obtained between the 3 factors of ASAS-R and the total scores of the 3 construct-related scales demonstrated adequate convergent validity. Total Cronbach's alpha value was 0.85, while the Cronbach's alpha of the three factors was 0.81, 0.55, and 0.83, respectively. This study demonstrated that ASAS-R is a valid and reliable instrument for measuring self-care agency among Portuguese medical stu-dents. |
