ABA Fundamentals

Cognitive-behavioral treatment of obsessions.

Ladouceur et al. (1995) · Behavior modification 1995
★ The Verdict

Exposure plus ritual prevention works on silent mental loops, not just visible acts.

✓ Read this if BCBAs helping adults with OCD who do covert counting, praying, or reviewing.
✗ Skip if Clinicians whose caseloads hold only visible tics or externalizing behavior.

01Research in Context

01

What this study did

Gaylord-Ross et al. (1995) worked with three adults who felt stuck in loops of mental rituals.

The team used a multiple-baseline design. Each adult got exposure plus response prevention.

Sessions targeted the silent counting, praying, or reviewing they did to feel safe.

02

What they found

All three people said their obsession discomfort dropped.

Daily life got easier and the gains held 8–11 months later.

Even purely mental rituals shrank when the client blocked them after exposure.

03

How this fits with other research

Last et al. (1984) saw no extra benefit when they added cognitive talk to exposure for agoraphobia.

R et al. show the opposite: blocking cognitive rituals mattered. The gap is in the target. G worked on general thoughts; R stopped the exact silent compulsion.

Rojahn et al. (1994) found that zero negative self-talk during exposure predicted panic relief. R’s method gives a road map: keep the client in the trigger until the covert ritual fades to zero.

Zeiler (1999) later showed that six months of maintenance keeps BDD gains for two years. R’s 8–11 month follow-up hints the same may hold for obsessions.

04

Why it matters

You can treat hidden rituals the same way you treat hand washing. Map the exact mental act, expose to the trigger, and block the ritual every time. Track until the thought drops to zero before ending the trial. This keeps gains alive almost a year later.

03Original abstract

Three patients with obsessive-compulsive disorder whose major complaints were obsessional thoughts with cognitive neutralization as opposed to overt rituals were treated with a cognitive-behavioral package. Cognitive neutralization involves both cognitive rituals and a variety of less ritualized coping strategies all designed to remove the thought and decrease discomfort. In a departure from earlier case studies, the patients were treated in a multiple baseline design across subjects. All three patients reported decreased discomfort and improved their professional and/or interpersonal functioning. Gains were maintained at follow-up (8 to 11 months).
