Stress and residential staff who work with people who have an intellectual disability: a factor analytic study

The present study describes the development of a questionnaire, and the subsequent collection of data, to gather information on the demands and supports which influence stress (as measured by anxiety and depression scales) in direct care staff who work with people with intellectual disability. The results from the questionnaire were also used to explore the relationships between the factors derived from the questionnaire and to consider how these may be influential in building organizational models. The questionnaire was specifically constructed to measure the demands and supports experienced by direct care staff. The participants included 216 staff working in community residential services for people with intellectual disability. These individuals included staff working for two British health trusts and similar staff working for one local authority. The questionnaire consisted of 33 demands items and 23 supports items. Separate factor analyses were conducted on the demands and supports scales. Analyses of the reliability and validity of the resulting factors were conducted. Stepwise multiple regressions were conducted to further explore the relationship of factors with the measures of anxiety and depression. Four factors were extracted from the demands scale and three factors from the support scale. There was some concern over levels of reliability and validity for individual factors; however, the reliability of the main scales appeared to be satisfactory. All but one support factor correlated significantly with levels of anxiety and depression. The factors explained a modest amount of the variance in the regressions. While there are some concerns about the psychometric properties of the questionnaire, it is argued that the scales and factors can be used to confirm and further understanding of the relationship between groups of demands, supports and stress in staff. The usefulness of the questionnaire as a means of diagnosing specific sources of demand and support is considered. It is suggested that the questionnaire could form the basis for assessment and subsequent intervention in houses where staff are reporting relatively high levels of anxiety and depression.
