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 Hammond's theory.
