Validation of the Behavioral Anger Response Questionnaire for Children (BARQ-C) in a large community sample of Vietnamese middle adolescents in Hanoi

BACKGROUND: Depression and other forms of psychological distress are common among Vietnamese adolescents and increase the risk of mental health problems in adulthood. As anger coping is a robust predictor of adolescent mental health difficulties, and there appear to be cultural variations in anger coping, a measure of adolescent anger coping styles that has been validated using a non-Western adolescent sample is required to inform and support early intervention to prevent or treat mental health difficulties in Vietnamese adolescents. This study examined the construct validity (structural and external) of the Behavioral Anger Response Questionnaire for Children in Vietnam (BARQC-V). METHODS: Baseline data sourced from a recent randomised control trial conducted with Grade 10 Vietnamese adolescents aged 14 to 16 (N = 1084) were used to examine multiple aspects of construct validity: factorial structure (evaluated using factor analysis); internal consistency (tested using Cronbach’s alpha coefficient); and external aspect (assessed using Pearson’s correlation coefficients between the BARQC-V and Vietnamese translations of the Coping Self-Efficacy Scale, Centre for Epidemiologic Studies Depression Scale Revised, Mental Health Continuum Short Form, and the Depression Anxiety and Stress Scale). RESULTS: Evaluating factorial structure using confirmatory factor analysis failed to converge on a solution. Exploratory factor analysis yielded a 5-factor structure model that explained 49.32% of the BARQC-V’s total variance and was deemed to be a good fit by the final confirmatory factor analysis. Cronbach’s alpha coefficients of the 5 factors demonstrated acceptable internal reliability for the BARQC-V’s sub-scales. Concerning concurrent validity, three sub-scales predicted well-being and mental health difficulties: the maladaptive anger coping styles Rumination and Direct Anger-out were positively associated with depression and distress, and negatively associated with coping self-efficacy and mental well-being; and the adaptive anger coping style Assertion was positively associated with coping self-efficacy and mental well-being, and negatively associated with depression. CONCLUSIONS: The BARQC-V provides a validated measure of three anger coping strategies used by adolescents in Vietnam (Rumination, Direct Anger-out, and Assertion) that can be used to improve detection and treatment of mental health difficulties in this population, and as a starting point by future research to develop a much-needed gold standard measure of anger coping for adults, adolescents and children world-wide.
