The psychometric properties of the Social Training and Achievement Record: II. Reliabilities and concurrent validities.
Three studies are reported which investigated the test-retest and inter-rater reliabilities of the Social Training and Achievement Record as well as concurrent validities with intelligence. Reliabilities of total and sub-scale scores as well as individual items are reported. Test-retest reliabilities over the period of one month were good for total scores, subscale scores and individual items. Inter-rater reliabilities were more modest. At times, inter-rater reliabilities of a small proportion of items were only at chance levels. Concurrent validities with Raven's Matrices and the Weschler Adult Intelligence Scale were comparable with other measures of adaptive behaviour. The role of direct observation in the assessment of adaptive behaviour, in particular with respect to individual skills being selected for teaching, is discussed.
