This study explores correlates of psychological distress and relationship satisfaction among concerned significant others (CSOs) of pathological gamblers. CSOs often seek help in dealing with the gambling problem and are influential in recovery, but little is known about the sources of their distress. A sample of 186 CSOs responded to media announcements offering telephone and bibliotherapy support. In multivariate models, CSOs who were spouses and who were younger reported more personal distress, and higher distress was associated with a greater number of CSO emotional and behavioral consequences. Lower relationship satisfaction was associated with more CSO emotional consequences, fewer gambler consequences, and greater severity of gambling problem. Implications for treatment are discussed.
