ABSTRACTPartial hospital programs (PHPs) represent an important part of the continuum of care for youth with severe and/or refractory OCD, yet little is known about clinical or utilization outcomes in this setting. The current study aimed to characterize symptom improvement and length of stay (LOS) among 185 youth with OCD treated in a PHP setting and to identify demographic, clinical, and treatment characteristics that predict these outcomes. Results demonstrate a 77.3% treatment response rate and a median LOS of 52 days. Holding other predictors constant, less symptom improvement was observed for youth with lower symptom severity at admission, in a racial or ethnic minoritized group, without comorbid anxiety, and receiving more treatment hours per day. Shorter LOS was observed among youth with public (vs. commercial) insurance, receiving more hours of treatment per day, and not taking a serotonin reuptake inhibitor (SRI). Clinical implications and directions for future research are discussed, including a critical need to understand and improve outcomes for minoritized youth.

ABSTRACTThis study tested whether a new training tool, the Exposure Guide (EG), improved in-session therapist behaviors that have been associated with youth outcomes in prior clinical trials of exposure therapy. Sixteen therapists in practice settings treated 46 youths with an anxiety disorder or obsessive-compulsive disorder (OCD). Therapists were randomly assigned to receive “gold-standard” exposure therapy training with weekly consultation (GS) or “gold-standard” training with weekly consultation plus the EG (EG). The primary outcome was therapist behavior during in-session exposures, observed using a validated coding system. Secondary outcomes included training feasibility/acceptability and observer-rated patient fear habituation; we also explored independent evaluator-rated clinical outcome. As hypothesized, therapists used similarly high rates of exposure with patients in both groups, but those in the EG condition used more fear-increasing behaviors and fewer fear-decreasing behaviors compared with those in the GS condition. Attendance data and therapist feedback support EG feasibility and acceptability. Patients treated by EG-trained therapists showed increased rates of in-session habituation. Descriptive clinical outcome data showed a slightly higher treatment response rate in the EG group (66.7% EG, 58.8% GS) that was more pronounced among patients completing a posttreatment assessment (83.3% EG, 60.0% GS). Results confirm the effectiveness of EG training for improving therapist delivery behaviors. Future studies will be needed to determine whether EG training can improve rates of patient treatment response via improved delivery behaviors. Public Health Significance: This study shows that the Exposure Guide, a therapist training tool, improves therapist delivery of exposure.

The current paper outlines the habituation model of an exposure process, which is a behavioral model emphasizing use of individually tailored functional analysis during exposures. This is a model of a therapeutic process rather than one meant to explain the mechanism of change underlying exposure-based treatments. Habitation, or a natural decrease in anxiety level in the absence of anxiety-reducing behavior, might be best understood as an intermediate treatment outcome that informs the therapeutic process, rather than as a mechanism of change. The habituation model purports that three conditions are necessary for optimal benefit from exposures: 1) fear activation, 2) minimization of anxiety-reducing behaviors, and 3) habituation. We describe prescribed therapist and client behaviors as those that increase or maintain anxiety level during an exposure (and therefore, facilitate habituation), and proscribed therapist and client behaviors as those that decrease anxiety during an exposure (and therefore, impede habituation). We illustrate model-consistent behaviors in the case of Monica, as well as outline the existing research support and call for additional research to further test the tenets of the habituation model as described in this paper.
