Alexithymia's link with health care utilization is unclear.Alexithymia may be overrepresented among clinical samples because of a proclivity to seek care, or alexithymia may prompt delay or avoidance of care, perhaps exacerbating illness. In 911 young adults, this study examined relationships between alexithymia (Toronto Alexithymia Scale-20: total and three factor scores) and the use of six health services during the past year: outpatient medical treatment, emergency room, hospitalization, psychotherapy, routine dental care, and nonprescription analgesics. Three potential mediators (insurance status, depression, and somatic complaints) were controlled to determine alexithymia's unique relation to utilization. The alexithymic difficulty in identifying feelings was linked to increased use of outpatient treatment, after controlling for potential mediators. Difficulty identifying feelings also was related to the use of psychotherapy and analgesics, but these relationships were accounted for by increased depression and somatic complaints, respectively. The alexithymic preference for externally oriented thinking was independently linked with the decreased use of outpatient treatment, to not having psychotherapy, and to being more likely to obtain preventive dental care. Our results may explain contradictions in the literature; separate alexithymic characteristics have different relationships with different types of health care utilization.
