A CONSTRUCT-VALIDITY STUDY OF A SELF-CONCEPT SCALE FOR A SAMPLE OF HOSPITAL NURSES

Using a sample of 107 registered nurses who were employed on medical-s urgical units and intensive care units in two acute care hospitals in California, the twofold purpose of this study was to provide additiona l evidence of the internal-consistency reliability and construct valid ity of scores on each of six dimensions of the Dimensions of Self-Conc ept (DOSC) Scale, Form W. Internal consistency estimates of reliabilit y of scores on the six subscales varied between .83 and .92. From each of the six factor subscales, 3 subtests each of five items were forme d, scored, and intercorrelated (18 subtests in all). Confirmatory maxi mum likelihood factor analyses for several alternative factor models i ndicated that a six-factor oblique model accounted for the greatest pr oportion of covariance in the matrix of 18 subtests.
