Data for: A Network Perspective on Comorbid Depression in Adolescents with Obsessive-compulsive Disorder
Participants The participants were 87 adolescents beginning treatment for OCD in the residential and intensive outpatient units of the Obsessive-Compulsive Disorder Center at Rogers Memorial Hospital. There were 41 (47.1%) males and 46 (52.9%) females, who ranged in age from 13 to 17 (M = 15.37, SD = 1.17). The racial/ethnic breakdown was Caucasian (n = 72), Asian (n = 10), Hispanic (n = 2), biracial (n = 2), and Black (n = 1). Board-certified staff psychiatrists, who are all experts in OCD and related disorders, used DSM-IV criteria to diagnose patients upon admission. These diagnoses were based on in-depth reviews of patients’ records from previous providers, information gathered by the hospital admissions staff, and an unstructured clinical interview with the adolescents and caretakers upon arrival at the treatment center. All participants received a primary diagnosis of OCD, and each consented for their data to be used in de-identified research. Current comorbid disorders according to these diagnoses were major depression (n = 21; 24.1%), depressive mood disorder not otherwise specified (n = 41; 47.1%, combined percentage = 71.3%), attention deficit hyperactivity disorder (n = 25; 28.7%), generalized anxiety disorder (n = 18; 20.7%), social anxiety disorder (n = 10; 11.5%), and tic/Tourette's syndrome (n = 8; 9.2%). Elevated comorbidities of current mood disorders is likely a result of the sample largely consisting of severe, clinically complex residential inpatients. Measures Children's Yale-Brown Obsessive Compulsive Scale Self-Report (CY-BOCS-SR; Scahill et al., 1997). The CY-BOCS-SR is a self-report questionnaire that evaluates the severity of OCD symptoms during the previous week. The scale includes 10 five-point Likert items which are summed to a score that ranges from 0-40 (a score of 16 or above signifies clinically significant severity). Reliability and validity of the self-report version of the scale are satisfactory (Scahill et al., 1997). The mean score in our sample was 26.1 (SD = 5.8, range = 24; Conelea, Schmidt, Leonard, Riemann, & Cahill, 2012). The 10 questions in the CY-BOCS-SR correspond to the 10 questions in the adult version of the scale (Y-BOCS; Goodman et al., 1989). Quick Inventory of Depressive Symptomatology (QIDS-SR; Rush et al., 2003). The QIDS-SR is a self-report questionnaire that evaluates the severity of depression symptoms. The scale includes 16 four-point Likert items summing to a total score ranging from 0-64. Reliability and validity of the scale are satisfactory (Rush et al., 2003). The mean score in our sample was 10.7 (SD = 5.9, range = 25).
