The clinical utility of validated cognitive-behavioral case formulations and intraindividual network analyses in adults with symptoms of obsessive-compulsive personality disorder: Evaluation of personalized treatment planning
A cognitive-behavioral case formulation (CBCF) is an idiographic theory of a person-situation that hypothesizes the relations between triggering situations, cognitions, and distress variables. This differs from the network approach (NA), which conceptualizes mental disorders as a “syndromic constellation of symptoms that hang together empirically.” Although both intraindividual approaches have previously been empirically supported, no previous research has evaluated the incremental clinical utility of using a combination of these approaches. Therefore, the purpose of the present study was to use intensive longitudinal assessment and statistical procedures to develop and implement a tailored treatment plan based upon a combination of results from the CBCF and intraindividual NA for four individuals with symptoms of obsessive-compulsive personality disorder and a comorbid depressive and/or anxiety disorder. Although there were few significant changes in relations between scales across time (6.4% to 22.5% of relations), tailored treatment based upon the validated CBCF and NA led to significant reductions in levels of constructs measured by idiographic and nomothetic scales and symptom inventories, and changes in network structure. Clinical and theoretical considerations, limitations, and future directions are discussed.
