Alexithymia is associated with anxiety among adolescents

Abstract

Background: The aim of this study was to explore the possible association between alexithymia and anxiety in a non-clinical sample of late adolescents.

Methods: The questionnaire was sent to 935 adolescents of whom 729 (78%) responded, thus forming the final sample. The mean age of the subjects was 19 years (range 17-21 years). The Finnish versions of the following scales were used: the 20-item Toronto Alexithymia Scale (TAS-20) was used to assess alexithymia, and anxiety symptoms were measured using the State-Trait Anxiety Inventory (STAI). Alcohol consumption was assessed using the Alcohol Use Disorders Identification Test (AUDIT), and depression symptoms were evaluated using the short form of the Beck Depression Inventory, as modified by Raitasalo (RBDI).

Results: The prevalence of alexithymia in the sample was 8.2%, with no statistically significant gender difference. The alexithymic subjects had significantly (p<0.001) higher mean STAI scores than the non-alexithymic subjects. A vast majority of the alexithymic subjects were highly anxious, in contrast to the low proportion among the non-alexithymic subjects. The highly anxious alexithymic subjects differed statistically and significantly from the highly anxious non-alexithymic subjects, with higher scores both in the AUDIT and the RBDI.

Limitations: The results are based on self-reported material alone and the cross-sectional design used in this study precludes the assessment of causal links.

Conclusions: The results suggest that anxiety symptoms are independently associated with alexithymia among late adolescents in general population.
