Abstract
The alternative model for personality disorders (AMPD) has been extensively studied over the past decade, but to date there is no direct comparison of the clinical utility of the AMPD model relative to the Section II personality disorder (PD) model in an ecologically valid design. The current study examined the clinical utility of an AMPD-informed assessment procedure and Section II PD assessment procedure as assessed by both patients and clinicians in a randomized controlled trial. A sample of 119 patients were randomly assigned to either an AMPD or a Section II PD assessment procedure. At the end of the assessment, patients filled out questionnaires pertaining to clinical utility, satisfaction, motivation for treatment, and general experience of the assessment. Clinicians who subsequently started treatment with these patients also completed two clinical utility questionnaires. There were no significant differences between the AMPD and Section II PD assessment procedure on patients' reported clinical utility, motivation for treatment, satisfaction, and general experience of the assessment nor were there significant differences between the models on clinician reported clinical utility. Explorative analyses revealed that, for patients, a positive relationship with the assessor was predictive of experienced utility. This study shows no superiority of the AMPD in terms of clinical utility but suggests that the alliance with the assessor is a particularly salient factor in clinical utility.
