Social support comes from relationships with family and friends. Social support includes emotional support or empathy and practical help or advice (1). Social networks are the size and structure of social contacts and relationships (1).


Social Support Risk/Pro

Risk and/or Protective Factor

Both social support and social networks have been linked to mental health outcomes.

Social support is a protective factor for mental health as social networks foster effective coping strategies, resilience and counteracts loneliness (2–4).

Not having enough social support can result in feelings of social isolation or loneliness. Small social networks and low social interaction have been associated with increased risk of depression and suicide (5,6). However, the quality of social networks also affects mental health. Toxic, destructive relationships have been associated with loneliness and decreased self-esteem (7).

Perceived social support can also affect outcomes and recovery of mental health difficulties. For example, people with depression who perceive their social support as low have been suggested to have increased symptoms and slower recovery (8).
