Abstract:
Alternate administration methods were tested for the Socialization (So) subscale of the California Psychological Inventory (CPI; H. G. Gough, 1994; H. G. Gough & P. Bradley, 1996) in 437 young adult men. One method administered the 46 CPI-So items in isolation from the CPI, whereas the 2nd method administered the 46 items embedded in the CPI. External validity measures of antisociality were also administered over the 2 sessions. Isolated administration produced somewhat higher internal consistency and significantly better concurrent validity and demonstrated construct validity as a measure of antisociality. Additional factor analytic studies of the CPI-So and CPI revealed that the 2 CPI-So versions had different factorial structures and that the embedded CPI-So subscale did not retain factorial integrity or an appreciable amount of reliable and uniquely interpretable variance.
