The role of nurses/social workers in using a multidimensional guideline for diagnosis of anxiety and challenging behaviour in people with intellectual disabilities.

AIMS AND OBJECTIVES

This study seeks (1) to investigate the impact of the implementation of the 'Diagnostic Guideline for Anxiety and challenging behaviours in clients with intellectual disability' on nurses/social workers' knowledge and self-efficacy; and (2) to evaluate the role of nurses/social workers in the diagnostic process when applying the guideline.

BACKGROUND

Nurses/social workers have extensive contact with clients with intellectual disabilities. Despite this key position, the contribution of nurses/social workers to the diagnosis of mental health problems and challenging behaviours is rather limited. The authors developed the multidimensional 'Diagnostic Guideline for Anxiety and challenging behaviours'. In this article, the implementation of this guideline is evaluated concerning knowledge and self-efficacy of nurses/social workers, as well the role of nurses/social workers in the diagnostic process.

DESIGN

This study employed a comparative multiple case study design.

METHODS

Qualitative and quantitative research methods.

RESULTS

Working with the 'Diagnostic Guideline for Anxiety and challenging behaviours' led to a statistically significant increase in knowledge and self-efficacy among the nurses/social workers in the experimental condition, compared with nurses/social workers in the control condition. Nurses/social workers and psychologists appreciated the more active contribution of the nurses/social workers in the diagnostic process.

CONCLUSIONS

Working with the guideline increased the knowledge and self-efficacy of nurses/social workers, and led to more active participation of nurses/social workers in the diagnostic process.

RELEVANCE TO CLINICAL PRACTICE

After following a training programme, nurses/social workers can effectively contribute to the diagnostic process in clients with anxiety and related challenging behaviours.
