RESUMO
Displacement activities (i.e., self-directed behaviors such as self-touching, scratching, and self-grooming) are a reliable ethological indicator of increased emotional and physiological arousal throughout the phylogenetic scale. We hypothesized that, in alexithymic individuals, the failure to regulate cognitively distressing emotions might result in increased displacement behavior. The nonverbal behavior of 30 patients with depressive or anxiety disorders was video-recorded during psychiatric interviews and analyzed using an ethological scoring system. Before being interviewed, each patient completed the Twenty-Item Toronto Alexithymia Scale (TAS-20), the Beck Depression Inventory (BDI), and the state form of the State-Trait Anxiety Index (STAI-S). Ethological data confirmed the hypothesis of the study. The patients with more pronounced alexithymic features showed a significantly higher frequency of displacement activities during interviews. At the same time, these patients reported levels of self-rated anxiety and depression equivalent to those reported by nonalexithymic patients. Such a dissociation between cognitive appraisal of emotion and nonverbal behavior reflecting increased emotional arousal supports the view that alexithymia implies a failure to elevate emotions from a preconceptual level of organization to the conceptual level of mental representations.

The relationship between nonverbal behavior and emotional awareness, as measured by the Toronto Alexithymia Scale, was studied in 24 young volunteers free of medical and psychiatric disorders. Multiple regression analysis revealed that nonverbal behavior during psychiatric interview was a significant predictor of the Toronto Alexithymia Scale total score independent of situational depression and anxiety. Subjects who had difficulty identifying and describing their feelings showed a combination of poor nonverbal expressivity and frequent self-directed behavior patterns indicative of tension and anxiety. In addition, subjects with a tendency toward externally oriented thinking showed more avoidance behavior during the interview. The ethological data of this study support clinical observations, which suggest that alexithymic traits interfere with both processing of emotion and interpersonal behavior.
