Abstract

Abstract : Abstract: This study aims to explore the relationships between delayed sleep phase disorder (DSPD) and emotional dysregulation in 240 patients (134 with cyclothymia, 81 with attention deficit hyperactivity disorder [ADHD] and 25 with both conditions). DSPD was assessed using the Morningness-Eveningness Questionnaire, followed by a clinical evaluation. Affective temperaments and emotional dysregulation were also investigated through the brief version of the Temperament Evaluation of Memphis, Pisa, Paris, and San Diego and the Reactivity, Intensity, Polarity, Stability questionnaires, respectively. Clinical variables were compared in patients with and without DSPD, and a logistic regression model was used to identify the predictive value of the clinical characteristics on the presence of DSPD. DSPD patients (19% of the total sample) were significantly younger than patients without DSPD, showed an about 4 times higher lifetime history of comorbid ADHD and cyclothymia, and reported higher scores in the irritable and cyclothymic temperamental subscales and in the affective instability and impulsivity dimensions. In the multiple logistic regression, we found a negative predictive value of increasing age on the presence of DSPD, whereas comorbid cyclothymia and ADHD and cyclothymic temperament seem to represent risk factors for DSPD.
