The Chinese EPOCH Measure of Adolescent Wellbeing: Evidence for Reliability and Validity of the Measure

The past decade has brought growing interest in supporting positive psychological functioning in young people. To support intervention efforts, adequate measures are needed. The EPOCH Measure of Adolescent Wellbeing assesses five positive psychological characteristics (engagement, perseverance, optimism, connectedness, and happiness), with studies finding evidence for reliability and validity in US and Australian samples. An initial study testing the Chinese version of the measure supported the factor structure of the measure, but also suggested that mean values are not directly comparable. The extent to which the measure is reliable and demonstrates evidence of validity with Chinese respondents is needed. Data collected across 11 Chinese student samples (N= 17,854) were used to test the psychometrics of the measure, providing support for the internal and cross-time consistency and content, convergent and divergent validity. The study further supports the EPOCH measure as a useful tool for measuring adolescent positive functioning across cultures.
