Interpreting the Personal Orientation Inventory Through the Five-Factor Model

This study was designed to determine how the Personal Orientation Inventory (POI; Shostrom, 1974) relates to the Five-Factor Model of Personality. Four self-report personality instruments were employed; the Personal Orientation Inventory, the Comrey Personality Scales (CPS; Comrey, 1970), the NEO Five-Factor Inventory (NEO-FFI; Costa & NcCrae, 1988), and the Five-Factor Nodel Adjective Factors (AF,", Costa & NcCrae, 1985b). Data were collected from 128 psychology students aged 18 to 30 years. Scores for the Five Factors were obtained by factor analysis combining responses from the CPS, the NEO-FFI, and the AF. Pearson product-moment intercorrelations were then computed for the Five Factors and the 12 scales of the POI. Although several scales of the POI overlap with the Five-Factor Hodel, it is apparent that the Five-Factor Model does not exhaust the constructs within the Personal Orientation Inventory.
