This presentation will showcase the key findings of the large-scale strength-based parenting research program conducted at Centre for Positive Psychology, University of Melbourne, led by Professor Lea Waters, PhD. This research program has examined the effects of SBP on children, teenagers and parents in sample sizes ranging from 100 to over 11,0000 using a range of different methods including survey research, vignette studies, intervention studies and longitudinal studies. Two overarching findings have been identified: 1) SBP is a protective factor and is inversely related to anxiety, depression, stress and negative emotions in children and teenagers; and 2) SBP is an enhancing factor and is positively related to life satisfaction, self-confidence, subjective wellbeing and positive emotions in children and teenagers. The research program has identified key mediators in the relationship between SBP and youth mental health including engagement, self-efficacy and persistence. An SBP intervention with parents found that SBP helps to boosts self-efficacy and positive emotions in the parents. Two SBP intervention with families found improvements in family happiness and family hardiness. This presentation will finish by discussing some of the unanswered questions in SBP and provide suggestions for future research on what more we need to know.
