Background: Behaviour that challenges has negative impacts on physical and emotional well-being and quality of life. Challenging behaviour scales are used to identify needs and evaluate interventions and must be valid measures. Criterion-related validity is important, and the best quality assessment uses direct measures of behaviour as criteria. Previous reviews of scales affirm their validity but present little supporting evidence. The current review examines the evidence presented in studies of validity. Methods: Searches of MEDLINE and PsycINFO to identify scales that focus on challenging behaviour and find publications that assess their criterion-related validity. Results: Searches identified twelve scales and 21 publications that assess validity. One assessment used direct measures of behaviour, and the remainder used indirect measures that themselves have limited evidence of validity, including membership of diagnostic or service groups and other scales. Conclusions: Little firm evidence of validity was found, but what was found is encouraging. (Publisher abstract)

Purpose: Challenging behaviours are defined in part by the risks of harm they present and the support of individuals who challenge would be improved with effective assessments of the risks posed by challenging behaviours. The purpose of this paper is to outline a model of risk assessment and review literature that provides relevant information. Design/methodology/approach: Literature review. Findings: Forensic risk assessment has a well worked-out and validated approach but tools used to assess challenging behaviours are not effective risk predictors. Applied Behaviour Assessment provides methods that can be more effectively used for risk assessment. Practical implications: There is a need to develop valid risk assessment procedures for assessing the risks presented by challenging behaviours. Originality/value: This is a fresh perspective on risk assessment in relation to challenging behaviours. (Publisher abstract)
