Gambling-related harms can impact the health and wellbeing of people who gamble and those around them in a negative way. The stress–strain–coping–support (SSCS) model proposes that coping styles and social support are key factors in how effectively people respond to a stressor (e.g., another person’s gambling problem). Based on the SSCS model, this study examined the roles of coping styles and social support in affected others' experience of harm and distress. The researchers found that being closer to the person with a gambling problem, being exposed to a more severe gambling problem, greater use of maladaptive coping styles, and lower levels of social support were associated with experience of greater harm and psychological distress.
