Cognitive Behavioral Therapy

Patients will receive a maximum of 18 1-hour sessions of Personal Constructs Therapy plus up to three 1-hour boost sessions between 3 and 5 months after the end of therapy. The intervention will follow a protocol designed specifically for this project based on the clinical experience of a previous pilot study. It will consist of 4 stages: (1) Analysis of patient's request, goals setting, identification of the main dilemmas, and other personal meanings relevant for self and others' construction; (2) feedback on the assessment results and problem reframing in terms of a "dilemma" and/or other personal meanings; (3) work on the dilemmas and/or other aspects of the self and others' construction; and (4) end of the therapeutic process outlining personal projects and future perspectives.
