Clinical utility questionnaire- Patient version
A specific outcome instrument measuring clinical utility for patients has been developed for the purpose of this study. Given the lack of such an instrument, a focus group was organized to collect implicit patient knowledge on clinical utility of PD assessment. The procedure has been described in a submitted paper. Briefly: a group of patients was asked to brainstorm about the concept of clinical utility of assessment; this procedure was repeated with other patient groups until no new information arose. The resulting themes were described and returned to all participants in a Delphi procedure until sufficient consensus (at least 75%) was reached. Following up on consensus on the definition, specific items were formulated to assess the aspects of clinical utility that had emerged from the focus groups, until sufficient consensus was reached. We found that patients defined clinical utility of assessment as the ability of an assessment procedure to 1) Be destigmatizing, 2) Start a process in which the patient starts to get more insight into patterns and become hopeful and motivated to change, 3) Summarize the core patterns which underly the patients’ problems, 4) Collaboratively work with the patient, and 5) Communicate transparently with the patient about the results of the assessment.
Clinical utility questionnaire – Clinician version
Although some very brief ‘top-down’ constructed measures for clinician clinical utility exist, we deemed these instruments incomplete and insufficient. Similarly as for patients, we used several focus groups and a subsequent Delphi procedure to define clinical utility of PD assessment from a clinician perspective and to formulate items to assess each of these aspects. Clinicians defined clinical utility of assessment as the ability of an assessment procedure to 1) Start a process in which the patient becomes curious about the problems he is facing and gets motivated to change, 2) Summarize the core patterns which underly the patients’ problems, 3) Give a balanced view of both vulnerabilities and resilience, 4) Make predictions (prognostic) useful in treatment (i.e. risks, expected treatment success, expected interactional patterns, useful treatment interventions), 5) Use accessible and easy to understand language and paint a vivid picture of the patient, and 6) Communicate transparently with the patient about the results from the assessment.
Achtergrond van het onderzoek
Rationale:
The traditional section II on Personality Disorder (PD) model has been contested for its limited validity and lack of clinical utility. To counter these shortcomings, DSM-5 has introduced in its section III an Alternative Model for Personality Disorders (AMPD). Previous AMPD studies have focused on separate criteria of the new model, e.g. by designing new instruments to assess sections of the AMPD. No studies have investigated the full AMPD assessment procedure and compared it to the existing, traditional DSM-5 PD assessment. This project will compare both assessment procedures (traditional/categorical (Section II) versus alternative/dimensional (Section III)) with regard to different aspects of clinical utility, from both a patient and clinician perspective.
Objective:
We will compare the AMPD model to the traditional (Section II) PD model with regard to patients’ and clinicians’ experience of the clinical utility of both models. As the AMPD model was designed to improve clinical utility, we expect that both patients and clinicians will report stronger clinical utility for the AMPD assessment procedure.
Study design:
Randomized Controlled Trial. Patients referred to de Viersprong for assessment and treatment will be randomly assigned to a traditional versus AMPD assessment procedure. Both procedures are comparable in terms of their multi-method approach and length of assessment and both have been manualized and approved by international experts. After having finished the assessment procedure, patients will complete a clinical utility questionnaire as well as questionnaires concerning process variables like satisfaction, motivation, and treatment readiness. Likewise, clinicians who will treat these patients, will assess the assessment report for clinical utility regarding the treatment to come.
Study population:
Patients are treatment seeking adults (18-65) referred to De Viersprong, a mental health care center specialized in the assessment and treatment of personality pathology.
Intervention:
In the traditional assessment procedure patients will have an intake consult with a clinician and the SCID-5-P will be administered (i.e., assessment as usual). In the AMPD admission procedure patients will be interviewed by a clinician and the STiP 5.1 and SCID-AMPD-II will be administered. In both conditions, screening questionnaires will be included after the initial intake consult.
Main study parameters/endpoints:
The primary outcome is clinical utility as assessed by patients and clinicians.
Nature and extent of the burden and risks associated with participation, benefit and group relatedness:
Burden will be minimal. Number of sessions will be the same in both conditions and also similar to the present standard assessment procedure (3 sessions). Patients will be asked to complete questionnaires at the end of the assessment procedure; an additional visit to the site is not necessary. Both groups will receive DSM-5 diagnoses (when applicable), according to the respective model. No impact is to be expected for treatment assignment.
Doel van het onderzoek
Research questions:
1. How do patients experience the clinical utility of the AMPD assessment procedure as compared to the clinical utility of the traditional, categorical (DSM-5 section II) assessment?
Based upon our review of the literature and the stated aim of the AMPD to improve clinical utility, we expect that the AMPD assessment procedure will be superior to the traditional categorical assessment procedure with respect to clinical utility as perceived by patients (primary outcome)
Based upon our expectation that the AMPD assessment procedure will be more clinically useful for patients, we also expect that the AMPD assessment procedure is superior to the traditional categorical Section II assessment with respect to motivation for treatment, outcome expectancy, and client satisfaction with the assessment procedure.
2. How do clinicians who will continue treatment with an assessed patient, experience the clinical utility of an assessment report based upon an AMPD assessment procedure as compared to a traditional, categorical assessment procedure.
Based upon our review of the literature and the stated aim of the AMPD to improve clinical utility, we expect that the AMPD assessment procedure will be superior to the traditional, categorical assessment procedure with regard to the clinical utility as perceived by the assigned therapist based upon the assessment report.
