Predictors of subjective ratings of stressor severity: the effects of current mood and neuroticism

AbstractRespondent‐based or subjective, ratings of stressor severity are posited to be influenced by systematic biases related to current mood and trait neuroticism which may confound associations between environmental stressors and psychological outcomes. The current study examined the effects of current mood state and neuroticism on subjective ratings of severity for real‐life stressors in a sample of 76 (30 males) undergraduates. Subjective ratings of stressor severity were collected in the context of an interview‐based stress assessment and were assessed on two separate occasions. Changes in mood state across the two assessments did not correspond with changes in subjective ratings of stressor severity. Neuroticism independently predicted subjective ratings of stressor severity, as did female gender and investigator‐based ratings of objective stressor severity. In addition, there was evidence to suggest that neuroticism fully accounted for observed associations between current mood state and subjective ratings of stressor severity. The findings are discussed with regard to the potential confounding influence of neuroticism in studies that rely on respondent‐based ratings of stressor severity in predicting psychological outcomes.
