“…Despite the large burden of depression in this population, few studies have attempted to establish the psychometric properties of common depression symptom measures in adults with ASD (for a review, see Cassidy, Bradley, Bowen, et al, 2018). Studies measuring depression in ASD have previously used a number of measures validated in the general population, including the Beck Depression Inventory-Second Edition (BDI-II; Moss et al, 2015), Depression Anxiety Stress Scales (Maddox & White, 2015;Nah et al, 2018), Hamilton Depression Rating Scale (Buchsbaum et al, 2001), Hospital Anxiety and Depression Scale (Powell & Acker, 2014), Montgomery-Åsberg Depression Rating Scale (Wentz et al, 2012), and Patient Health Questionnaire-9 (PHQ-9; Hedley et al, 2018) without assessing the validity of those measures in ASD. In recent years, several studies have attempted to fill this gap, reporting psychometric properties of the BDI-II (Gotham et al, 2015), Hospital Anxiety and Depression Scale (Uljarević et al, 2018), and PHQ-9 (Arnold et al, 2019).…”
