# McLean OCD Institute for Children and Adolescents: Overview, Rationale, and Description of Symptomatology and Functional Impairment

## TL;DR

This paper describes the characteristics of adolescents with OCD in a residential treatment center and aims to improve understanding of this specialized care.

## Contribution

The study provides a detailed characterization of adolescent OCD patients in residential treatment, including symptom severity and comorbidities.

## Key findings

- Adolescents in the program had severe OCD symptoms and significant functional impairments.
- Common comorbidities and medication profiles were identified among the patient population.
- The paper outlines best practices for treating adolescents in residential and partial hospitalization programs.

## Abstract

Background/Objectives: Residential treatment represents an important level of care for adolescents with severe and/or treatment-refractory obsessive–compulsive disorder (OCD). Despite accumulating evidence supporting the treatment efficacy and cost-effectiveness of insurance-based intensive OCD treatment in residential settings, few data exist that characterize the population of adolescent patients utilizing this level of care. As a result, residential treatment may be poorly understood by patients, their families, and referring providers, which may delay appropriate treatment for adolescents with OCD. Here, we characterize the patient population at an intensive residential treatment center (RTC) and partial hospitalization program (PHP) for adolescents (Mage = 15.23) with a primary diagnosis of OCD. Methods: We examine quantitative data collected from 168 adolescents admitted to the McLean OCD Institute for Children and Adolescents for the treatment of primary OCD or a related disorder over a three-year period. We also conduct analyses on a subset of patients (n = 120) who participated in the Child and Adolescent Routine Evaluation (CARE) Initiative (McLean Child Division-Wide Measurement-Based Care Program) to further characterize this patient population with a lens toward additional comorbidities and factors impacting prognosis. Results: The current paper describes the severity of symptom presentation, comorbidities, psychotropic medication profiles, and disruption to personal and family functioning. Analyses also include the prevalence of OCD subtypes and co-occurrence among varied presentations. Conclusions: In addition to identifying common clinical presentations in an RTC/PHP, this paper further aims to detail best practices and clinical rationale guiding a specialty RTC/PHP to inform families, providers, and payors about the individuals that most benefit from this level of care.
