A Daily Stress Inventory: development, reliability, and validity.

This article describes the development of the Daily Stress Inventory, a measure introduced to provide researchers and clinicians with a psychometrically sound self-report instrument for the daily assessment of the sources and individualized impact of relatively minor stressful events. It was designed to assess sources of stress not typically assessed by major life-event scales. Generalizability coefficients indicate that the scale has significant homogeneity and a useful degree of stability. Several studies investigating the concurrent and construct validities suggest that the scale measures the construct commonly referred to as "stress." Implications for uses in theoretical and basic research as well as clinical assessment are discussed.
