Positive affect inertia uniquely differentiates formerly depressed individuals from healthy controls
Previous studies have shown that emotional dynamics, that is, moment to moment variability and inertia of emotional states, are related to depression, but have no significant contribution after their overlap with mean affect is taken into account. However, few studies considered clinical samples. In our study, we compared a sample of euthymic formerly depressed persons ( n = 94) at high risk of depression recurrence and healthy controls with no h…
Validation and Psychometric Properties of the Polish Version of the Skin Picking Scale-Revised
The Skin Picking Scale-Revised (SPS-R) is an 8-item self-report measure of skin picking behaviors. It includes two subscales related to skin picking symptom severity and picking-related impairments. The study aimed to assess the psychometric properties of the Polish version of the SPS-R in a sample of adults reporting skin picking. The sample of 764 participants was recruited from the general population through an online survey. Among them, 159 m…
Assessing Excoriation (Skin-Picking) Disorder
Excoriation (skin-picking) disorder (SPD) is a psychiatric condition with variable clinical presentation. We developed the Diagnostic Interview for Skin Picking Problems (DISP), a semi-structured interview designed to assess (1) DSM-5 criteria for SPD and (2) several clinical features of SPD, including the frequency and duration of picking episodes, and the proportion of time devoted to picking at different body areas. The DISP was administered a…
