Care Competencies Training Enhances Adolescents' Well-being: A Randomized Controlled Trial.

Objective: This intervention study seeks to assess the impact of a care competencies training program on students' well-being. Method: This randomized controlled trial involved 191 Vietnamese adolescents (65.4% female, Mage = 16 years and 8 months) in a 7-week intervention study that used video vignettes to build their care competencies. Validated scales were used to determine their care competencies (Care Competencies Questionnaire for Adolescents) and well-being (Strengths and Difficulties Questionnaire, Perceived Stress Scale and Satisfaction with Life Scale) at three points in time: before, immediately after, and two months after the intervention. The full-information maximum likelihood approach was applied to latent growth curve modeling (LGM) in Mplus 8.5 to estimate the initial level (i.e., intercept) and the change (i.e., slope) in care competencies and well-being among adolescents over time. Factor scores of LGMs were saved for correlation and multiple linear regression analysis by using SPSS (version 26.0) to explore the relationships between the changes in care competencies/failures and the changes in well-being. Results: Results showed that, next to a significant increase in care competencies and a significant decrease in care failures, other well-being variables also significantly changed in the intervention group. In the intervention group, but not in the control group, changes in care competencies and failures consistently and significantly predicted changes in well-being. Conclusion: The results support the potential of the video vignette-based intervention to promote the development of adolescents' care competencies.
