Syllabus: Why Do Obsessions and Compulsions Persist?
Separate baseline levels, early change, later change, and outcome.
Why you’re reading it. Use a clinical time course to scrutinize maintenance without assuming that improvement identifies its cause.
A question to consider. What intervention or repeated-measure comparison could show that a change in incompleteness produces later improvement rather than accompanying it?
Why this reading
If a process sustains a problem, its change should help explain improvement. This study follows harm avoidance and incompleteness during treatment, allowing readers to distinguish change together from evidence about mechanism.
Before you read
A baseline predictor and a change predictor answer different questions. Temporal ordering strengthens some interpretations but does not eliminate common causes. A naturalistic treatment study observes care without randomly assigning its proposed mechanisms.
Read for
- Follow who entered the analyses, when measures were taken, and which changes predicted later outcomes.
- Compare individual tests with results after correction for multiple comparisons.
Consider afterwards
- What design would separate the effect of changing incompleteness from other processes that change during the same treatment?
Editorial context
Analyses concerned 65 adult treatment completers, with 55 available for early/late comparisons. There was no randomized comparison, long-term follow-up, or medication information. Early incompleteness change predicted outcome, but a nominal late harm-avoidance finding did not survive multiplicity correction. These self-report associations do not establish causal mediation, treatment efficacy, or a universal order of recovery.
