The ZAS, the construction and psychometric analysis of a scale of care, given to chronic psychiatric patients

L.J. van der Werf, A.W. Goedhart

An observation-scale was developed to assess several aspects of care. The scale (ZAS, `Zorg-Aanbod-Schaal') was examined in a regional sample of 541 chronic psychiatric patients. Six factor analytically derived subscales were identified. The interjudge agreement between 41 pairs of judges was sufficient, and mostly good, for item- and subscale-level. The possible use of the ZAS is discussed.
