Fidelity of a strengths-based intervention used by dutch shelters for homeless young adults.

Objective: In a cluster randomized controlled trial, this study aimed to investigate the effectiveness of and fidelity to Houvast (Dutch for "grip"), a strengths-based intervention to improve the quality of life for homeless young adults.

Methods: Fidelity was measured six months after professionals and team leaders at five Dutch shelters for homeless young adults finished their training in Houvast. Fidelity was measured with the Dutch version of the strengths model fidelity scale, which consists of ten indicators distributed across three subscales: structure, supervision, and clinical practice.

A strengths based method for homeless youth: effectiveness and fidelity of Houvast.

Background: While homelessness among youth is a serious problem, there is little information about evidence-based interventions for homeless youth. In cooperation with professionals and youths, Wolf (2012) developed Houvast (Dutch for 'grip'): a strengths based method grounded in scientific and practice evidence. The main aim of Houvast is to improve the quality of life of homeless youths by focusing on their strengths, thus stimulating their capacity for autonomy and self-reliance.

The Eating Disorder Diagnostic Scale: psychometric features within a clinical population and a cut-off point to differentiate clinical patients from healthy controls.

The Eating Disorder Diagnostic Scale (EDDS) is a brief self-report measure for diagnosing anorexia nervosa, bulimia nervosa and binge eating disorder. Research has provided evidence of the reliability and validity of this scale in non-clinical populations. Our study is the first to examine the psychometric features of the EDDS in a clinical population of eating disordered patients.
