The Co-Worker Involvement Instrument.
McNair, Jeff; Rusch, Frank R.
The paper describes the development and psyhometric validation of an instrument to measure co-worker involvement with employees with handicaps in supported employment settings. The Co-worker Involvement Instrument contains 10 items pertaining to physical integration, social integration, vocational integration, training, associating frequency, associating nature, befriending, advocating, evaluating, and information giving; and was tested in 12 supported employment programs in Illinois. The reliability study was broken into studies of inter-rater reliability and test-retest reliability. Based upon 68 ratings made by rater pairs, the total score inter-rater reliability was estimated to be .82. In a second sample in which 18 different rater pairs scored the instrument, the total score was estimated to be .80. Based upon the comparison of ratings by the same rater separated by a period of time, the total score test-retest reliability was estimated to be .88. The validity of the instrument was supported by a face validity study in which only one item was considered appropriate to include by less than 80% of raters, and the instrument overall was considered an appropriate measure by 90% of the raters.
