Abstract
Problem: Depression and substance use disorders (SUDs) frequently co-occur, complicating recovery outcomes. Despite screening recommendations, depression remains underdiagnosed in many SUD treatment settings.
Methods: This mixed-methods program evaluation examined depressive symptoms among adults in an Intensive Outpatient Program (IOP) using the Patient Health Questionnaire (PHQ-8). Depression screenings were conducted at intake, four weeks, and eight weeks. Eight participants meeting inclusion criteria were assessed. Data included demographics, treatment engagement, and PHQ-8 scores.
Results: PHQ-8 scores significantly declined from baseline (M = 11.75, SD = 6.52) to eight weeks (M = 5.13, SD = 5.05), t(7) = 2.76, p = .028, indicating improved depressive symptoms. All participants completed the program with high therapy attendance (M = 86.25%) and medication adherence (100%).
