Late-onset stress symptomatology (LOSS) scale – short form: development and validation

Objectives: Late-onset stress symptomatology (LOSS) is a phenomenon observed in older combat veterans who experience increased combat-related thoughts, feelings, and reminiscences corresponding with the changes and challenges of aging. Previously, we developed the LOSS Scale to assess LOSS. This paper describes the development and validation of a LOSS Scale short form (LOSS-SF) to screen veterans in various settings who may be actively re-examining their past wartime experiences.

Method: Three studies examined the reliability and validity of the LOSS-SF in separate samples of male combat veterans age 55 and older (total N = 346). Veterans were administered measures via telephone and mail survey. Correlation and regression analyses examined the reliability and validity of the LOSS-SF.

Results: The LOSS-SF exhibited strong internal consistency (alpha = .93), test-retest reliability (2 week interval on average; r = .88), and good concurrent validity with the LOSS Scale (r = .81). Convergent and divergent validity were supported by the pattern of correlations between the LOSS-SF and other construct measures.

Conclusion: The LOSS-SF is a reliable and valid measure to quickly assess thoughts, feelings, and reminiscences about past combat experiences in older veterans and identify those veterans in distress who may benefit from psychological interventions..
