What this trial studies

This study investigates the feasibility, acceptability, and effectiveness of a blended psychotherapeutic treatment program called B-DIT, which combines face-to-face therapy with online modules for adults with personality pathology. The program is structured in three phases: an individual phase lasting about two months, a four-month group phase, and a four-month booster phase to reinforce positive changes. By integrating traditional therapy with e-health components, the study aims to enhance treatment accessibility and foster a sense of ownership among clients regarding their treatment. The research is conducted by the Dutch mental health care institute De Viersprong in collaboration with OnlinePsyHulp.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with mild to moderately severe personality functioning impairments.

Not a fit: Patients with severe personality disorders, acute crisis risks, or certain mental health conditions like schizophrenia may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could improve treatment outcomes and recovery for individuals with personality disorders.

How similar studies have performed: While blended interventions have shown promise in other mental health areas, there is limited evidence specifically targeting personality pathology, making this approach relatively novel.
