Specific formulation feedback in dynamic-relational group psychotherapy of perfectionism.

In this article, we describe how individualized feedback, in the form of a clinical formulation, is used in our dynamic-relational group treatment of perfectionism (Hewitt et al., 2015), a core vulnerability or transdiagnostic personality factor. The authors discuss briefly their conceptualization and assessment of perfectionism as well as other aspects of patients' functioning, and the use of both psychodynamic and interpersonal models to derive, for individual patients, their unique formulation or idiosyncratic model of their perfectionistic and related behavior. Moreover, we describe the process of providing the formulation feedback to each patient in preparation for group psychotherapy and, finally, provide an illustrative case. (PsycINFO Database Record
