Learning disability care staff's emotional reactions to aggressive challenging behaviours: development of a measurement tool.

OBJECTIVES: To describe the development of a rating scale measure of caregivers' emotional reactions to aggressive challenging behaviour, and to report preliminary psychometric data for the scale.
DESIGN: Using previous research on staff working with people with learning disabilities, a range of likely emotional reactions to challenging behaviours were selected for possible inclusion in a rating scale measure.
METHODS: A total of 83 care staff from 23 community residences for people with learning disabilities rated their recent emotional reactions to aggressive challenging behaviour using 18 emotion items. A further sample of 18 care staff participated in a test-retest study after the initial stages of scale development.
RESULTS: A rating scale was developed on the basis of a factor analysis and further item analysis. The measure has two subscales: feelings of depression/anger (10 items), and feelings of fear/anxiety (5 items). The subscales have a high internal consistency, good test-retest reliability and are relatively unaffected by social desirability biases.
CONCLUSIONS: The emotional reactions to aggressive challenging behaviour scale has excellent face and construct validity, and other preliminary psychometric data are promising. The scale has a number of potential research and clinical applications.
