Abstract

[Abstract]: The Subjective Stress Scale (SSS: Bramston & Bostock, 1994) was developed to measure stress in people with a mild intellectual disability. In previous research, the SSS was found to measure two broad dimensions of stress, the first a General Worry factor, the second a factor that tapped concerns about Negative Interpersonal Relations (Bramston & Fogarty, 1995). The present study sought to continue this line of research by introducing a slightly modified form of the SSS, to be known as the Lifestress Inventory (LI) and examining the psychometric properties of the scale when administered to a new sample of 221 people with mild intellectual disabilities. Confirmatory factor analysis indicated that three underlying factors corresponding to General Worry, Negative Interpersonal Relations, and Coping were sufficient to account for the correlations among the items in the LI. Rasch analysis indicated some improvements to the scoring format for the LI and also showed that the most easily experienced stressors were associated with the Negative Interpersonal Relations dimension. The refinements introduced by the LI and the further demonstration that some of the broad stress dimensions identified in the general population can also be found in people with an intellectual disability represent important milestones for researchers interested in exploring reactions to stress among this population.
