It talks about incompleteness/not just right experiences (a desire to get things 'just right' or 'complete' and to reduce a sense of discomfort) and how they are characterized differently from harm avoidance (a desire to prevent harm and reduce anxiety).Here are some snippets from the article I paraphrased that I thought were important:
One of the similarities across Obsessive-Compulsive Spectrum Disorders is “not just right experiences” (NJRE’s) which refer to the repetition of certain actions or behaviors until someone feels “just right” or gains a sense of “completeness” (Coles, Frost, Heimberg, & Rhéaume, 2003). NJRE’s have provided some challenges for clinicians as the compulsions are driven by sensory discomfort and some studies show NJREs are associated with high symptom severity (Ferrão et al., 2012) and poorer response to treatment (Foa, Abramowitz, Franklin, & Kozak, 1999).
Treatment may be more difficult because young people with NJREs can be affected by virtually every part of the day, whereas more typical OCD symptoms are triggered by specific things (Reid, Storch and Lewin, 2009).
Treatment outcome data suggests that NJRE dominated OCD may have a poorer response (Summerfeldt, 2004; Tallis, 1996) and may benefit most from behavioral exercises encouraging tolerance to the emotional state of “incompleteness” rather than dysfunctional cognitions (Pietrefesa and Coles, 2009).
