The Salient Stressor Impact Questionnaire (SSIQ)

Abstract

High stress is known to affect health, but stress impact, determined by events and responses to them, has not been studied systematically. For the Salient Stressor Impact Questionnaire (SSIQ), the impact of events was assumed to depend on their salience and chronicity and the impact of responses on their chronicity and intensity with greater unfavorable appraisal associated with greater response. The SSIQ assessed a person’s two most salient stressors. Chronicity items discriminated between clinically stressed and nonclinical participants and measured the chronicity of stressful feelings (distress) and the event. The remaining items measured the degree of distress and unfavorable appraisal. The SSIQ showed good test-retest and internal consistency reliability, concurrent validity, and stability across diverse populations. Exploratory analyses grouped items into distress, chronicity, and appraisal elements, and confirmatory analysis revealed a good fit to the hypothesized model. Preliminary data suggest that the SSIQ will be useful for studying relationships between stress and health.
