[A brief scale for measuring subjective prognosis of gainful employment: findings of a study of 4279 statutory pension insurees concerning reliability (Guttman scaling) and validity of the scale].
The psychometric properties of a 3-item scale for the assessment of subjective vocational disability were tested in 4279 blue-collar workers. Internal consistency of the scale was estimated by Guttman scaling. To evaluate construct validity the scale was compared to other measures of vocational ability, functional capacity, comorbidity, psychic status, and indicators of occupational handicap. The results are highly satisfactory, and the scale can be recommended for further use in rehabilitation research. Ongoing research is discussed.
