Do stressful life-events or sociodemographic variables associate with depression and alexithymia among a general population?--A 3-year follow-up study.

This 3-year follow-up study examined background factors, stressful life-events, and changes in alexithymia and depression scores in four groups of subjects from a general population (N = 1,339): alexithymic (A), depressed (D), simultaneously alexithymic/depressed (AD), and non-alexithymic/non-depressed (O). Alexithymia was assessed using the 20-item version of the Toronto Alexithymia Scale (TAS) and depression using the 21-item Beck Depression Inventory (BDI). A questionnaire screening sociodemography and stressful life-events was also used. The results showed that alexithymia was associated with male gender and blue-collar working, whereas depressive symptoms associated with female gender, older age, poor subjective health, poor financial situation, and low life satisfaction. During the follow-up the sum of stressful life-events was higher among groups AD and D than in groups A and O. The most common stressful life-events were the death of a close relative or friend, a negative change in the health of a family member, and financial problems. The TAS scores decreased only in groups A and AD. The BDI scores decreased in group AD but remained relatively unchanged in group D. Interestingly, if only those without depressive symptoms are considered, alexithymia appears to be a rarer phenomenon than has been reported previously. Furthermore, it seems that depressive symptoms were chronic and long-lasting among the general population.
