<p>This article presents a case study illustrating the contemporary integrative cognitive approach, a multidimensional model that weaves together cognitive, behavioral, affective, motivational, developmental, interpersonal, and sociocultural dimensions. The approach promotes dimensional and idiographic formulation to understand psychopathology as the expression of life trajectories. The case of Sofía, a 30-year-old outpatient with personality-spectrum difficulties, exemplifies how this model guides individualized intervention through collaborative meaning-making. Over two years of psychotherapy, work focused on affect regulation, schema modification, and the reconstruction of autobiographical narratives within a safe therapeutic relationship. Quantitative outcome monitoring and a qualitative first-person evaluation converged to show significant improvements in functioning, emotional awareness, and agency. The case underscores how integrative cognitive psychotherapy can support patients in becoming active protagonists of their own life stories.</p>
