Assessment & Research

Treatment compliance and outcome in obsessive-compulsive disorder.

★ The Verdict

In EX/RP, focus compliance checks on exposure homework and rationale understanding—the only pieces that cut OCD severity.

✓ Read this if BCBAs running exposure therapy for adults or teens with OCD.
✗ Skip if Clinicians who treat anxiety without exposure or who use purely medication plans.

01Research in Context

01

What this study did

The team tracked adults with OCD through exposure and ritual prevention therapy. They scored how well clients followed four parts of the plan: doing exposures, stopping rituals, self-monitoring, and understanding the rationale.

After treatment they checked which parts of compliance matched lower OCD scores.

02

What they found

Only two things mattered: doing the exposure homework and grasping why it works. Clients who nailed those showed the biggest symptom drop.

Surprisingly, perfect ritual prevention logs or daily self-monitoring sheets added no extra benefit.

03

How this fits with other research

Prasher et al. (1995) showed that warm, nondirective therapist talk early in panic treatment builds later cooperation. Jaffe et al. (2002) now says cooperation itself can be sliced: some slices predict outcome, others don’t.

Mace et al. (1990) defined resistance as fighting or avoiding therapist questions. The new data flip the lens: even willing clients may spend time on low-impact tasks like detailed self-monitoring, pulling effort away from the heavy hitter—exposure.

Fledderus et al. (2010) found that avoiding feelings fuels anxiety. Jaffe et al. (2002) hints that understanding the exposure rationale may lower that avoidance, giving clients a reason to stay in feared situations.

04

Why it matters

Stop checking every ritual log during EX/RP. Spend your minutes reviewing the exposure plan and asking clients to explain why it helps. If they can sell the rationale back to you and show completed homework, you’re on the path to fewer OCD symptoms.

03Original abstract

Exposure and ritual prevention (EX/RP) is an effective treatment for obsessive compulsive-disorder (OCD), although it is neither universally nor completely helpful. Compliance with EX/RP treatment procedures has been linked theoretically to posttreatment outcome, yet empirical exploration of this relationship has been insufficient. In this study, therapists were asked to rate the treatment compliance of 28 consecutive patients who received EX/RP on a fee-for-service basis. Results indicated that understanding the treatment rationale and compliance with in-session and homework exposure instructions, but not with ritual prevention and self-monitoring of rituals, was significantly related to posttreatment OCD symptom severity. Clinical implications of these findings and future directions in treatment compliance research with OCD patients are discussed.
