The confinement imposed by measures to deal with the COVID-19 pandemic may in the short and medium term have psychological and psychosocial consequences affecting the well-being and mental health of individuals. This study aims to explore the role played by group membership and social and personal identities as coping resources to face the experience of the COVID-19 confinement and radical disruption of social, work, family and personal life in a sample of 421 people who have experienced a month of strict confinement in the Region of Madrid. Our results show that identity-resources (membership continuity/new group memberships, and personal identity strength) are positively related to process-resources (social support and perceived personal control), and that both are related to better perceived mental health, lower levels of anxiety and depression, and higher well-being (life satisfaction and resilience) during confinement. These results, in addition to providing relevant information about the psychological consequences of this experience, constitute a solid basis for the design of psychosocial interventions based on group memberships and social identity as coping resources.

Introducción: la evidencia científica sobre los efectos del uso de medios sociales en línea sobre el bienestar en la población adolescente es heterogénea. En general, usos pasivos (recepción, visualización de contenidos sin interacción) y mayor tiempo de pantalla se relacionan con menor bienestar en contraposición con usos activos (interacciones directas e intercambios interpersonales). Objetivo: Esta investigación explora el tipo y motivo de uso de medios sociales, estableciendo su diferencia por identidad de género y orientación sexual, así como efectos sobre bienestar eudaimónico y estrés de minorías. Método: estudio transversal, 1259 adolescentes; 14-19 años (M = 16.19; DE = 1.08). Escala motivos de uso de redes sociales, Bienestar eudaimónico, Estrés de minorías, tiempo de pantalla, tipo de perfil. Resultados: mayor tiempo de uso se relaciona con búsqueda de pareja, conexión social o establecer amistades. Los adolescentes gay y bisexuales (GB) perciben más estresores distales en línea. Las mujeres tienen mayores niveles de bienestar. Discusión: los perfiles públicos en hombres GB favorecen la autoexpresión, aunque el estrés de minorías puede relacionarse con discriminación, rechazo o exclusión. La socialización diferenciada puede contribuir a un nivel elevado de bienestar en las mujeres. Usos activos como pasivos favorecen el bienestar eudaimónico de los adolescentes. Introduction: The scientific evidence regarding the effects of online social media use on the well-being of adolescents is mixed. In general, passive uses (receiving, viewing content without interacting) and more screen time are related to lower well-being when compared with active uses (direct interactions and interpersonal exchanges). Objectives: This study examines the types and motives for social media usage amongst adolescents, differentiating them by gender identity and sexual orientation, as well as its effects on eudaimonic well-being and minority stress. Method: A cross-sectional study was conducted with 1259 adolescents, aged 14 to 19 (M = 16.19; SD = 1.08), analysing the Scale of Motives for Using Social Networking Sites, eudaimonic well-being, the Sexual Minority Adolescent Stress Inventory, screen time and profile type. Results: The results found that longer use time is related to finding partners, social connection and friendships; that gay and bisexual (GB) adolescents perceive more distal stressors online; and that females have higher levels of well-being. Discussion: The public profiles of GB males increase self-expression, although minority stress can be related to discrimination, rejection or exclusion. Differentiated socialization may contribute to a higher level of well-being in females, with both active and passive uses positively effecting eudaimonic well-being in adolescents.
