Adolescence involves a progressive distancing from attachment figures to support the process of separation and individuation, making it a period of psychological vulnerability to suicidal behavior. Quality peer relationships serve as protective factors. However, the strict lockdown implemented from March to May 2020 for health reasons led to a total suspension of in-person peer interactions and a forced return to the family setting. This study explores the experience of that suspension among adolescents who attempted suicide following the lockdown. We conducted face-to-face, semi-structured exploratory interviews using the Interpretative Phenomenological Analysis (IPA) qualitative methodology with three adolescent girls aged 15 and 16. An ambivalent experience of the first lockdown was evident. Pre-existing psychological distress appeared to have been exacerbated. Lastly, digital social networks seemed to offer an ineffective substitute for peer relationships. In the current context of a documented resurgence in suicide attempts among adolescent girls, with etiological factors still unidentified, a qualitative exploration appears relevant. However, recruitment and data collection specificities in this domain suggest extending inclusion criteria over time and targeting optimal moments for data collection.
