Response biases as a confound to expressed burden among spousal caregivers of suspected dementia patients

Burden among family caregivers has yet to be adequately assessed relative to social desirability response sets. This study examined the impact of two different response biases relative to expressed burden among spousal caregivers of suspected dementia patients. In addition to individual social desirability, it was hypothesized that a distinct social desirability construct exists as a function of one's perception of self within relationships. As predicted, a significant inverse association was apparent between expressed burden and this systemic response bias (as measured by the Edmonds Marital Conventionality Scale), whereas this association was not apparent with a measure of individual social desirability (the Marlowe-Crowne Social Desirability Scale). This finding suggests that systemic social desirability may exist as a significant response bias.
