CPI FACTOR SCORES TO FORMULATE PERSONALITY TYPES 455 existence of a relatively small number of modal types (as defined by the major CPI factors) suggests that code type approaches may be practicable with the CPI. Nontest characteristics of such groups could be noted and interpretative aids for the CPI prepared. Of course, the results of this study should be evaluated within the context of the sample involved. It remains to be seen whether other samples (psychiatric patients, groups that have professed adjustment problems, etc.) exhibit the same pattern frequencies as normals. In any case, the feasibility of a type approach with the CPI seems promising enough to encourage future inquiries.
SUMMARY
CPI scale scores were correlated with specially-scored CPI factor scales, and the results indicated that such factor scores could be estimated reasonably by the standard scales. By the use of CPI scales as measures of the two major factors of that instrument, the incidence of profile types in a normal sample was tabulated. For both males and females, six types accounted for SOY0 of the protocols: the first three types accounted for over 50% of the individuals. It was suggested that this type of analysis might contribute to interpretation of CPI protocols.
