Developed, cross‐validated, and compared a CPI short‐form that consisted of those CPI items repeated from the MMPI plus additional CPI items with the CPI short‐form developed by Burger (1975). Scores for the two short‐forms were extracted from standard CPIs administered to 81 consecutive, male, psychiatric ward admissions and 38 inpatient volunteers at a VA Neuropsychiatric Hospital. Comparisons of intercorrelational matrices, scale correlations, and profile validities support a hypothesis that the short‐forms may prove to be useful predictors of the full‐version CPI. Comparisons between the two short‐forms showed that the Repeated Items Short‐Form was equal or superior to the other short‐form in approximating the full‐version CPI. Further assessment of a CPI short‐form that is simultaneously an MMPI short‐form appears justified in light of both the current results and previous data by Rodgers (1966), which showed that the repeated item constitute a satisfactory estimate of the MMPI for research purposes.
