The present study examined the psychometric properties of the Life Effectiveness Questionnaire Version H (LEQ-H), an instrument for the assessment of life skills in project work (PW) context with Singaporean students. Specifically, we examined the internal consistency, as well as discriminant and convergent validity of the subscales in LEQ-H. Second, we tested the proposed measurement model against four other alternative models and confirmed with a second sample. In addition, we examined the invariance of the measurement tool across gender. A total of 1,264 secondary school students were recruited from nine typical government funded co-educational secondary schools in Singapore. All the subscales had adequate internal consistency but two subscales lacked convergent validity. Five competing models were compared using confirmatory factor analyses. The results provide evidence of a seven first-order measurement model of the LEQ-H. Multigroup analysis demonstrated invariance of the factor forms, factor loadings, factor variances, and factor covariances, error variances and disturbances across gender. In summary, the findings affirm that the LEQ-H, with the seven first-order measurement model, can be an appropriate measurement tool to assess the effects of PW on students’ life skills such as time management, social competence, achievement motivation, task leadership, emotional control, active initiative and self-confidence.
