ISTA-F
Instrument zur stressbezogenen Tätigkeitsanalyse bei Freelancern
Short abstract
The ISTA-F measures the stress-related working conditions of freelancers and is used in the field of ABO psychology. The test construction was based on the ISTA by Semmer, Zapf and Dunckel (1999) and the action-theoretical requirements, stress and resource model by Greif (1991). The ISTA-F comprises three main scales (stressors, resources & requirements) with different numbers of subscales and a total of 87 items. Reliability: The internal consistency according to Cronbach was between alpha = .62 and alpha = .95 and the retest reliability between rtt = .54 and rtt = .82 (interval: 1-3 months). Validity: The procedure is valid in terms of content. The factorial validity was confirmed by confirmatory factor analysis. As proof of construct validity, the significant intercorrelations of the subscales as well as correlations with three state of mind scales (irritation, psychosomatic complaints, joy of work/pride) can be used. To check the criterion validity, regression analyses were calculated with the result that the ISTA scales prove to be predictors of well-being indicators.
