Purpose: There are known connections between emotions and psoriasis; however, we have not established a clear pathway for this association. This study aimed to explore correlates of difficulties in emotional regulation in patients with psoriasis and predict the influence of emotional regulation in psoriasis disability.
Method: Two hundred and twenty eight participants completed the Difficulties in Emotion Regulation Scale, Self-administered Psoriasis Area and Severity Index, Psoriasis Disability Index, and Brief Symptom Inventory. Spearman's correlation and a hierarchical stepwise multiple regression were carried out to analyse associations.
Results: Results indicated that patients with the most recent diagnoses experienced greater difficulty in acting in accordance with goals (r = .16, p < .05) but lesser difficulty in engaging in goal-directed behaviour (r = -.15, p < .05). Those with greater satisfaction with treatment exhibited fewer difficulties in emotional regulation (r = -.23, p < .01). The patients who experienced greater difficulty in emotional regulation perceived greater psoriasis severity (r = .15, p < .05) and disability (r = .36, p < .05), reported more psychopathological symptoms (correlations between .46 and .56), and missed work/school more frequently (r = .24, p < .05). Impulse control proved to be the strongest predictor to psoriasis disability (β = .34).
Conclusion: The results highlighted the relationship between emotional regulation difficulty, disease characteristics, and psychological variables in psoriasis disability emphasizing the importance of including a broader approach in clinical management of psoriatic patients.
