Case conceptualization in psychotherapy allows clinicians to hypothesize the origins of patients’ difficulties and to plan interventions. The LIBET model (Life and Themes Implication Biased: Elicitation and Treatment, Sassaroli et al., 2022) is a cognitive-behavioral framework designed to construct a case conceptualization. The present study aims to investigate differences in the dimensions assessed by the LIBET model among individuals without a diagnosis, those with symptomatic disorders, and those with comorbid personality disorders. A total of 738 participants completed a psychological assessment, which included semi-structured interviews, LIBET-Questionnaire, and self-report instruments. Findings revealed group differences in the selection of strategies used to manage psychological distress, as well as significant differences across three out of the four metacognitive axes included in the LIBET model. Metacognitive axes were found to be correlated with personality rigidity and potential predictors of psychosocial wellbeing, supporting the model’s sensitivity. The study presents limitations primarily related to participant recruitment and research design. Further studies will be required to enhance the validation of the LIBET model. Nonetheless, the LIBET-Questionnaire appears to be a promising tool for assessment purposes and for monitoring therapeutic progress. It can help identify phases of improvement or lack of progress and guide adjustments to the treatment plan within a shared therapeutic framework.
