Short STAI-Y XXXX scales: validation and normative data for elderly subjects.

@entity1 @entity148 @entity308
OBJECTIVES: The aim of this study was to develop short forms of the STAI-Y trait and state scales and associated norms suitable for the screening of @entity148 in elderly populations. METHOD: This study was based on population-based cohorts of older @entity1 from two epidemiological French studies that each included one subscale of the STAI-Y, i.e. state and trait @entity148 scales. For both scales, the most discriminative items were retained and their factorial structure was examined using principal components analysis. Internal consistency (Cronbach's alpha) was estimated and cut-offs and norms were computed. RESULTS: A 10-item STAI-Y version produced scores similar to those obtained with the full form of the STAI-Y. The factorial structure of the shortened form is comparable to that of the full scales. Results showed good internal consistency (alpha coefficients were 0.92 and 0.85 for short STAI-Y state and trait scales, respectively). Moreover, both short STAI-Y state and trait scales correctly classified 88% of the @entity1 using a cut-off point of 23. Norms for both short trait and state @entity148 scales are provided according to age, gender, educational level and @entity308 . CONCLUSION: Both shortened scales have similar factorial structure and internal consistency to the longer scales and classify anxious/non-anxious elderly with acceptable accuracy. The shorter form is likely to be more acceptable to elderly @entity1 through reduction of fatigue effects.
