Marital separation and health: stress and intervention.

Marital separation is a stressful life event implicated in much current thinking and practice in mental health, health psychology and psychosomatic medicine. This study examines marital separation in a controlled, prospective design. The participants were 314 Health Maintenance Organization (HMO) subscribers followed over a two year period. Marital separation was experienced by 127 of these participants early in the two-year study period. A stratified random half of these separated individuals participated in a short-term psychoeducational group intervention, "Seminars for the Separated." Measures of psychosocial adjustment and medical utilization were analyzed to describe correlates of marital separation and to evaluate the intervention. Statistically significant increases in medical utilization by people experiencing marital separation were observed in comparisons with married control subjects. Much of this increased utilization occurred in the year surrounding the actual separation and may be accounted for by mental health visits as well as nonmental health contacts with the health plan. The effects of the intervention were not evident until controls for baseline levels of medical utilization were introduced into the multivariate analysis. Even then, intervention effects were slight. Methodological problems and implications for further study are presented.
