A film-based intervention (Intinn) to enhance adolescent mental health literacy and well-being: multi-methods evaluation study

Purpose Adolescent mental health is a global concern. There is an urgent need for creative, multimedia interventions reflecting adolescent culture to promote mental health literacy and well-being. This study aims to assess the impact of a film-based intervention on adolescent mental health literacy, well-being and resilience. Design/methodology/approach A pretest-posttest intervention with a multi-methods evaluation was used. A convenience sample of ten schools facilitated students aged 15–17 years to engage in an online intervention (film, post-film discussion, well-being Webinar). Participants completed surveys on well-being, resilience, stigma, mental health knowledge and help-seeking. Five teachers who facilitated the intervention participated in post-implementation interviews or provided a written submission. Analysis included paired-t-test and effect size calculation and thematic analysis. Findings Matched pretest-posttest data were available on 101 participants. There were significant increases in well-being, personal resilience and help-seeking attitudes for personal/emotional problems, and suicidal ideation. Participants’ free-text comments suggested the intervention was well-received, encouraging them to speak more openly about mental health. Teachers similarly endorsed the intervention, especially the focus on resilience. Originality/value Intinn shows promise in improving adolescents’ mental health literacy and well-being. Film-based interventions may encourage adolescents to seek professional help for their mental health, thus facilitating early intervention.
