The psychosocial stressors of siblings of people with experiences of psychosis (SOPEP): A systematic narrative review across cultures

This study aimed to synthesise the psychosocial stressors of siblings of people with experiences of psychosis (SOPEP). Understanding the specific needs of siblings across diverse cultures would help mental health services to provide culturally specific psychosocial family and sibling-centred support. This may result in improved relationships between families, better psychosocial well-being for siblings and better outcomes for patients.Following PRISMA guidelines, a systematic review was conducted to explore the psychosocial stressors of SOPEP. Six databases were utilised to identify literature using qualitative methodology.Twenty-two studies were included that investigated the Psychosocial Stressors of SOPEP. SOPEP's experiences were influenced by various stages: individual factors, social factors, physical and macro-level environments. Six key components contributed to SOPEP's psychosocial stressors and facilitated or hindered their intentions, behaviours and experiences of caregiving. These were the SOPEP's beliefs about psychosis, caregiving beliefs, family and cultural values, personality traits, pragmatic challenges and access to resources.Globally, SOPEP and families may benefit from their involvement in family interventions and individual support that facilitates caregiving and acknowledges their responsibilities, resources, psychosocial needs and emotional experiences.
