That Was Easy! Expectancy Violations During Exposure and Response Prevention for Childhood Obsessive-Compulsive Disorder.
Have kids predict their fear before each ERP task—those who over-predict improve faster, so spotlight the "easier than expected" moment.
01Research in Context
What this study did
The team watched kids with OCD during exposure and response prevention.
Before each task the child guessed how scared they would feel.
After the task they rated how scary it really was.
The study tracked how often kids over-predicted their fear.
What they found
Kids who said "this will be awful" but then felt fine improved faster.
The more their guesses were wrong in a good way, the quicker OCD dropped.
In short, being surprised by "easier than I thought" sped recovery.
How this fits with other research
McLennan et al. (2008) showed ERP works for autistic children too.
Their single case proves you can run the same exposure logic with ASD added.
Zemestani et al. (2022) tested ERP against ACT in adults.
Both beat pills alone, but the adult trial did not track expectancies.
Wetterneck et al. (2006) used ERP on tics and saw quick gains that partly faded.
The new data say nothing about relapse, so keep booster sessions in mind.
Why it matters
Ask your client to rate fear before and after each exposure.
When they say "that was easier," pause and highlight the mismatch.

03Original abstract
Violating expectancies during exposure therapy is proposed to promote inhibitory learning and improved treatment outcomes. Because people tend to overestimate how distressing emotionally challenging situations will be, violating expectations of distress may be an intuitive way to promote treatment outcome during exposure-based cognitive-behavioral therapy (CBT). This study evaluated overpredictions of distress during exposure tasks in 33 youth with obsessive-compulsive disorder (OCD; ages 8-17) participating in CBT. Youth with more variable prediction accuracy and a higher proportion of overpredictions experienced more rapid symptom reduction, b = -0.29, p = .002. Underpredictions were less common toward the end of therapy as youth experienced less severe OCD, b = 0.12, p= .001. Findings suggest that although youth often accurately predict the intensity of exposure, overpredictions are common as well. The frequency of these overpredictions promoted treatment outcome, supporting expectancy violations as one indicator of inhibitory learning during exposure therapy.
