It involves three components: wilderness adventure, community challenge and individual mentoring. This longitudinal study aimed to investigate changes in self-efficacy, resilience, connectedness and wellbeing in students participating in Project K. Eighty students (59% male) were recruited from five secondary schools across the North Island of New Zealand for a quasi-experimental study. Participants displaying delinquent behaviour, self-harm, suicidal ideation, or an eating disorder were excluded. Over 14 months, six waves of measurement were completed by Project K participants (n = 49), while four waves of measurement were completed by a control group (n = 31). Analyses using multilevel models showed that completion of Project K had substantial positive effects on selfefficacy, resilience, and wellbeing, although the effect on connectedness was not significant. We conclude that Project K appears to be an effective positive youth development programme for adolescents with low self-efficacy.14 - 23Journal article344235Publisher's own licenceMassey_Dark1701 Psychology1702 Cognitive Sciences
