title: The Contribution of Alexithymia to Obsessive-Compulsive Disorder Symptoms Dimensions: An Investigation in a Large Community Sample in Italy.
abstract: Poor attention has been dedicated to the relation between Alexithymia and specific OCD symptoms dimensions. Knowledge about which Alexithymia domains are the most affected ones in OCD dimensions could inform clinical practice, suggesting the need for the introduction of psychotherapeutic interventions targeting Alexithymia deficits. The current study aimed to investigate which OCD symptom dimension correlated with Alexithymia domains. A total of 425 community individuals (mean age = 27.80, SD = 9.89, 60% women) completed measures of Alexithymia, OCD symptoms dimensions, anxiety, and depression. Moderate correlations emerged between Difficulty Identifying Feelings and Hoarding (r = .36, p < .001) and Checking symptoms (r = .34, p < .001) and between Difficulty Describing Feelings and Pure Obsessing (r = .31, p < .001). Difficulty Identifying Feelings uniquely predicted OCD symptoms (β = 0.20, t = 3.96, and p < .001), after controlling for anxiety and depression. A main effect emerged of Alexithymia on Ordering (β = 0.70, t = 2.50, p < .05) and Pure Obsessing symptoms (β = 0.043, t = 2.08, and p < .05). Psychotherapeutic interventions specifically targeting Alexithymia should be integrated in the treatment of Ordering and Pure Obsessing symptoms. Difficulty Identifying Feelings and Difficulty Describing Feelings should be addressed in the psychotherapeutic treatment of Hoarding, Checking, and Pure Obsessing, respectively.
