The Emotional Reactions to Challenging Behaviours Scale (ERCBS) was designed to evaluate the emotional states of support staff facing challenging behaviours from recipients. Employees working with People Exhibiting Intellectual Disability (PEIDs) are exposed to challenging behaviours. Exposure to challenging behaviours can affect the occupational well-being of these employees. It is thus important for investigators to have instruments assessing employees' emotional reactions to challenging behaviours reliably and validly. In this study, we translated the ERCBS into Spanish and inquired into the psychometric and structural properties of the adapted instrument. We relied on a sample of 232 employees working with PEIDs. Confirmatory factor analysis indicated that the ERCBS was best modelled as a two-factor measure involving a negative emotion factor and a positive emotion factor. The two factors were highly correlated (0.547), suggesting that a distinction between "emotional" and "non-emotional" individuals might be relevant when using the ERCBS. Alpha and omega reliabilities were satisfactory. ERCBS scores did not differ between men and women. ERCBS scores correlated negatively with participants' age and years of service with PEIDs. Our study suggests that the Spanish version of the ERCBS can be used to assess emotional reactions to challenging behaviours among employees working with PEIDs.
