Primary Outcome Measures

Name	Time	Method
<p>The main study parameter is change in the frequency and severity of aggressive<br /><br>behaviour after NMDHL treatment. Aggressive behaviour will be evaluated by pre-<br /><br>and post-therapy administration of two self-report questionnaires and one<br /><br>partner questionnaire. Predictors that are hypothesised to be of influence on<br /><br>treatment effect are offender subtype, psychiatric co-morbidity, personality<br /><br>traits, stress reactivity, cognitive bias, motivation and treatment integrity.<br /><br>Offender subtype, psychiatric co-morbidity, personality traits, motivation and<br /><br>treatment integrity are assessed by self-report measures, a researcher-rated<br /><br>risk assessment instrument B-SAFER, semi-structured interview, and audiotaping<br /><br>sessions. Stress response is measured by cortisol level and a-amylase level<br /><br>before and after a stress induction test MAST. Social-cognitive bias is<br /><br>measured by FaceGen Modeller test. </p><br>

Secondary Outcome Measures

Name	Time	Method
<p>Treatment integrity of NMDHL treatment will be assessed. In order to score<br /><br>treatment integrity an intervention checklist will be developed. NMDHL<br /><br>treatment sessions are being audiotaped and coded by means of the intervention<br /><br>checklist. The intervention checklist concerns protocol adherence as well as<br /><br>non-specific therapeutic techniques.</p><br>
