Development and Assessment of the Personal Emotional Capital Questionnaire for Adolescents

Higher emotional capital is associated with enhanced positive emotions, social relationships, social capital and human capital. The present study developed and evaluated a personal emotional capital questionnaire for adolescents (PECQ-A) that assessed 10 components of this capital. The PECQ-A was administrated to two samples of Iranian 15-year-olds from two Iranian cities (N1 = 600, N2 = 300, total N = 900) recruited using multistage random cluster sampling. A confirmatory factor analysis of the first sample confirmed the ten-factor structure of the PECQ-A. The reliability of PECQ-A was acceptable (Cronbach's α = .90, McDonald's ω = .88, AVE = .57, Composite reliability CR = .89). Analyses of the second sample revealed that the PECQ-A and its components exhibited convergent validity when compared to the Mental Health Continuum-Short Form (MHC-SF), the students' GPAs, and the students' mathematics and natural sciences scores. The PECQ-A demonstrated divergent validity when contrasted with the Depression Anxiety and Stress Scale (DASS21). Test-retest reliability was acceptable. Invariance measurement was confirmed for the PECQ-A. A MANOVA identified several gender differences. PECQ-A scores were not sensitive to the order that the questionnaires were administered. The results suggest that the PECQ-A is a valid and reliable measure of personal emotional capital suitable for use with adolescents.
