According to self-determination theory competence is a basic psychological need that is crucial for wellbeing. Social contexts strongly influence whether competence is supported or thwarted. Given that social media is a pervasive social context within adolescents' lives, it can play a crucial role in competence development. Three qualitative methods were used to investigate mid-adolescents' perspectives of how their social media use impacts competence. Participants included 36 students aged 15 years from four Australian schools. All participants completed a rich picture mapping activity and focus group discussions. A sub-sample of 11 students participated in follow-up interviews. Reflexive thematic analysis generated two overarching themes. The first theme cultivating competence includes sub-themes; enhancing social competencies, mastery experiences and goal accomplishment, and social media expertise. The second theme constraining competence includes sub-themes; ineffectance within the social media environment, interfering with sleep, and hindering learning. Findings demonstrated that social media contributes to today's adolescents encountering unique experiences with regards to competence development. Furthermore, adolescents' interactions on social media have broad implications for competence within online and offline realms. This study identifies aspects of social media use that can be targeted to help adolescents engage with social media in ways that cultivate rather than constrain competence.
