This article describes the construction and validation of 7 scales for the California Psychological Inventory (Gough, 1975(Gough, ,1987 based on a socioanalytic interpretation of the Five-Factor Model. The scale construction differed from traditional rational and empirical approaches in that it regarded responses to personality items as speech acts-skilled performances that create an effect on an audience. Expected group differences across 10 samples (total N = 763) and relations with other personality inventory scores, vocational choice, educational achievement, drug use and anti-socia1 behavior, job performance, and observer ratings supported the construct validity of the scales.This article describes the construction of seven scales for the California Psychological Inventory Gough, 1975Gough, ,1987 designed to assess social performance. This set of scales, constructed in the late 1970s, prefigured the development of several personality inventories based on the Five Factor Model (FFM; McCrae & John, 1992), including the Hogan Personality Inventory (HPI; Hogan, 1986) and NEO-PI (Costa & McCrae, 1985). Previous publications (Hansson, Hogan, Johnson, & Schroeder, 1983;Hogan, Carpenter, Briggs, & Hansson, 1985;Johnson, 1983) have mentioned these scales only in passing. By detailing the unique strategies underlying the construction of these CPI scales, this article clarifies the conditions under which FFM-based inventories such as the HPI and NEO-PI successfully predict real-life performance.The article is organized according to the four-step model of construct validation, called conceptual analysis, used by Gough (1987) to explicate the meaning of CPI scale scores. The article does not use the traditional method and results sections, although it does conclude with an overall discussion of the findings.Requests for reprints should be sent to
