Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study aims to explore the feasibility, acceptability, and effectiveness of a new blended psychotherapeutic treatment program based on Dynamic Interpersonal Therapy (B-DIT) for adult clients with personality pathology. Blended interventions have the potential to improve treatment accessibility and cost-effectiveness for individuals with personality pathology and promote a sense of agency and ownership among clients regarding their treatment as compared to traditional Face-to-Face (FTF) approaches. This may improve treatment outcome and recovery.

The B-DIT intervention, developed collaboratively by Dutch mental health care institute De Viersprong and OnlinePsyHulp, integrates FTF therapy and online modules into a cohesive treatment program. The program spans three phases: an individual phase lasting approximately two months, followed by a four-month group phase, and concluding with a four-month booster phase to reinforce positive changes. Face-to-face therapy sessions and online treatment modules are utilized alternately and complementarily throughout all treatment phases.

The primary study aims are (1) to monitor and evaluate the feasibility of B-DIT; which includes evaluating client satisfaction, treatment drop-out rates, user parameters related to online modules, and an interview-based qualitative analysis of therapists' and clients' experiences; and (2) to gather initial effectiveness data based on Routine Outcome Monitoring (ROM) measurements, complemented by a Single Case Experimental Design (SCED). The research questions are as follows:

1. How acceptable is the blended treatment program, B-DIT, for adult clients with personality pathology and their therapists?
2. What is the effectiveness of B-DIT for adult clients with personality pathology in terms of progress in reducing symptom burden, overall functioning, and personality functioning, including changes in process measures such as mentalizing ability, epistemic trust, and agency?
3. Exploratively, the effects on these process and outcome measures across treatment phases will be compared to ascertain if observed changes align with the presumed working mechanisms of the intervention.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This study aims to explore the feasibility, acceptability, and effectiveness of a new blended psychotherapeutic treatment program based on Dynamic Interpersonal Therapy (B-DIT) for adult clients with personality pathology. B-DIT integrates face-to-face (FTF) therapy and online modules into a cohesive treatment program, offering potential advantages in terms of treatment accessibility and cost-effectiveness for individuals with personality pathology. Additionally, blended interventions may have added value compared to traditional FTF approaches by fostering a greater sense of agency and ownership among clients regarding their treatment. While e-health and blended interventions have demonstrated promising treatment outcomes across various mental health areas, there is limited evidence for interventions targeting personality pathology.

B-DIT, developed collaboratively by Dutch mental health care institute De Viersprong and OnlinePsyHulp, addresses this gap and provides a blended intervention for clients with mild to moderately severe personality pathology. The program spans three phases: an individual phase lasting approximately two months, followed by a four-month group phase, and concluding with a four-month booster phase to reinforce positive changes. Face-to-face therapy sessions and online treatment modules are utilized alternately and complementarily throughout all treatment phases.

The primary study aims are (1) to monitor and evaluate the feasibility of B-DIT; which includes evaluating client satisfaction, treatment drop-out rates, user parameters related to online modules, and conducting a qualitative analysis of therapists' and clients' experiences; and (2) to gather initial effectiveness data based on Routine Outcome Monitoring (ROM) measurements, complemented by a Single Case Experimental Design (SCED). The SCED allows drawing conclusions about effectiveness based on a relatively small sample, while accommodating potential refinements to the intervention during the study period. The following research questions will be addressed:

1. How acceptable is a blended treatment program, Dynamic Interpersonal Therapy (B-DIT), for adult clients with personality pathology and for their therapists?
2. How effective is B-DIT for adult clients with personality pathology in terms of progress in improving symptom burden, overall functioning, and personality functioning, along with changes in process measures (mentalizing ability, epistemic trust, agency)?
3. Exploratively, the effects on these process and outcome measures across treatment phases will be compared to determine if observed changes are consistent with the presumed working mechanisms of the intervention.

Participants in the study will receive care as usual. In complement to regular Routine Outcome Monitoring assessments as integrated part of treatment, participants will be asked to complete an additional 26-item questionnaire repeatedly during their treatment and over a one year follow-up period in a Single Case Experimental Design with four phases:

Phase A - Baseline Waiting List (before start of treatment) - with a minimum of 3 weeks; Phase B - Intensive treatment phase (10 weeks of individual treatment followed by 30 weeks of group treatment) - 30 weeks; Phase C - Booster treatment phase - 16 weeks; Phase D - Follow-up phase after the end of treatment - 12 months.

The (impact of) expectations with regards to their treatment will be assessed at baseline and at end of treatment. Clients and clinicians will be questioned about their experiences in the treatment program (at the end of treatment) by means of semi-structured qualitative interviews.

Intervention Type OTHER

The B-DIT intervention, developed collaboratively by Dutch mental health care institute De Viersprong and OnlinePsyHulp (http://www.onlinepsyhulp.be), integrates FTF therapy and online modules into a cohesive treatment program for clients with personality pathology. Both FTF and online treatment components are anchored in the Dynamic Interpersonal Therapy (DIT) framework (Lemma et al., 2011).The program spans three phases: an individual phase lasting approximately two months, followed by a five-month group phase, concluding with a four-month booster phase to reinforce positive changes. Face-to-face therapy sessions and online treatment modules are utilized alternately and complementarily throughout all treatment phases. Both verbal psychotherapy and art therapy are offered as treatment modalities in the face-to-face treatment sessions. The program is implemented by a multidisciplinary team.
