A procedure for factoring an unlimited pool of items with results for the c.p.i. using young australian males

Abstract

A factorial solution of the items of the California Psychological Inventory (C.P.I.) for a sample of 116 14-year-old boys is presented, and related to Hammond's theory of personality structure and the distinction between factorial and clinical scales. A general procedure for factor analysing a pool of items of unlimited size was formulated, involving a two-stage factor analysis and a technique for refining the second order scales.The six main factors were called "Personal adequacy and well-being", "Serious/flippant life attitude", "Sociability and interpersonal competence", "Community alienation", "Rigidity of thought", and "Authoritarianism". Only the first and last scales were not independent. The first four factors fitted Harnmond's theory.

An analysis of the coopersmith self-esteem inventory: A discussion of two studies

“…Higher order factors were then extracted to see if a single factor of self-esteem would be identified as underlying the inventory responses. The method is explained in detail by Lovegrove and Hammond (1973).…”

The Significance of Three Scales Identifying a Delinquent Orientation among Young Australian Males

“…This was assessed by noting the correlations between the 'Community alienation', 'Delinquency-proneness', and Socialization scales, and the six scales which were identified in the factor analysis of the items of the CPI (Lovegrove, 1971;Lovegrove and Hammond, 1973). Table 6 shows the inter-correlations between the factor scales and these scales for the delinquent and non-delinquent samples.…”

“…However, a clinically derived scale is irrelevant for this purpose, since it is multi-factorial. Consequently, the use of the factorial scale promotes a more integrated and parsimonious system of theory and measurement (Lovegrove and Hammond, 1973).…”

“…THIS PAPER** presents an evaluation of the validity of a tactortal scale ('Community alienation') which has been derived from the items of the California Psychological Inventory (CPI) (Lovegrove, 1971;Lovegrove and Hammond, 1973). On the basis of the content of this scale's items, it was felt that it may be useful for identifying" a delinquent orientation.…”

Item selection for two personality scales: the affective and analytic dimensions

“…A dimension similar to the affective-analytic dimension was not obtained in a cluster analysis of the items of the POI (Silverstein & Fisher, 1975), or in a factor analysis of the POI scales (Tosi & Hoffman, 1972). Factor analyses of the MMPI scales (LaForge, 1962) and items (Hunter, Overall, & Butcher, 1974), CPI scales (Nichols & Schnell, 1963;Rogers & Shure, 1965;Schludermann & Schludermann, 1970;Springbob & Struening, 1964) and items (Lovegrove & Hammond, 1973), EPI items (Howarth, 1976;Howarth & Browne, 1972;Stanley & Watkins, 1972) and CPS scales (Ottomanelli, 1972) failed to yield a factor resembling the affectiveanalytic dimension. The dimension also failed to appear in the factor analytic studies of the item pool from which the CPS items were drawn (Comrey, 1961(Comrey, , 1962(Comrey, , 1964(Comrey, , 1965Comrey & Duffy, 1968;Comrey & Jamison, 1966;Comrey, Jamison, & King, 1968;Comrey & Schlesinger, 1962;Comrey & Soufi, 1960, 1961.…”
