Collecting three waves of panel data offered an unusual opportunity to examine the long-term outcomes of the use of mental health services. Data are drawn from a panel study of autoworkers. Waves 1, 2, and 3 consisted of 1,597, 1,288, and 1,136 workers, respectively, from four closing and 12 non-closing plants in Southeastern Michigan. Our results revealed a surprising finding: use of mental health services, whether in the general or specialty sectors, had a negative impact on the subsequent mental health of autoworkers in our sample. The use of mental health services is associated with increased levels of psychological distress. Further, we show that the negative association between use of mental health services and distress was greater for certain demographic groups, notably Blacks, men, older workers, the poorly educated, and the unemployed, depending upon the type of service used. Finally, we sought to uncover the reasons for the negative impact of services use. Results suggest that self-blame, for one, contributed to the negative impact of using mental health services.
