<div>In this article, the research on incompleteness experiences</div><div>in obsessive-compulsive disorder (OCD) is reviewed.</div><div>Empircal data concerning the phenomenological</div><div>differentiation between self-related incompleteness (SI)</div><div>and ‘not just right experiences’ (NJREs) are presented.</div><div>Diagnostic</div><div>instruments and empirical results concerning</div><div>frequency, association with different symptom-based subtypes</div><div>and with symptom severity as well as the specificity</div><div>of NJREs for OCD are outlined. Considerations and results</div><div>concerning the theoretical conceptualization of incompleteness</div><div>phenomena are summarized (SI as an OCD-specific</div><div>form of depersonalisation/derealization, with the</div><div>‘Two-Stages-Model’ as an etiological hypothesis; NJREs</div><div>as sensation-based perfectionism related to obsessivecompulsive</div><div>personality features and tic disorders, with a</div><div>presumed neurobiological origin). So far, there is a lack of</div><div>studies evaluating modifications of cognitive-behavioral</div><div>methods tailored to incompleteness-related OCD.</div
