An item factor analysis of the CPQ administered to a sample of New Zealand school children : a thesis submitted in partial fulfilment of the requirements for the degree of Master of Arts in Education at Massey University
The 1963 version of the Children's Personality Questionnaire was administered to 374 New Zealand children aged from 8 to 14 years with a mean age of 11 years 5 months attending state primary and intermediate schools. Both Forms A and B were administered to each child. Items designed to load on CPQ factor B (Intelligence) were omitted for simplicity of analysis, leaving 130 Items in each Form. Data obtained were factor analysed using the principal components method, Varimax rotation, communalities in the diagonals, and proceeding to oblique rotation. Separate analyses were carried out on Form A and Form B and thirteen factors extracted from each Form, as follows, for comparison with the remaining thirteen CPQ factors. Form A Factors: A1 Assertiveness A2 Conformity A3 Dependency A4 Serious-mindedness A5 Shyness A6 Security A7 Confidence A8 Self-satisfaction A9 Irresolution A10 Self Sentiment A11 Defeatism A12 Placidity A13 Participation Form B Factors: B1 Self-control (Conformity) B2 Self-reproach B3 Confidence B4 Sociability B5 Tender-mindedness B6 Emotional Maturity B7 Consociation B8 Laxity B9 Serious-mindedness B10 Egocentricity B11 Passivity B12 Realism B13 Friendliness Items from all CPQ factors except I (Tough minded-versus-Tender minded) showed significant loadings (sig. = ± 0.30) on four or more of the emergent factors, indicating that the items did not clearly define the CPQ factors which they are alleged to measure. However, 89 items from Form A and 85 items from Form B showed significant loadings on only one emergent factor. Ten of the CPQ factors provided recognisable contributions to the emergent factors. Form A factors showed only two significant intercorrelations (sig. = ± 0.30) whereaa there were six such intercorrelations among the Form B factors and thirteen among the CPQ factors. It is suggested that the Form A factors may provide a more suitable reference frame for the measurement of personality dimensions among New Zealand children. Before proceeding to adaptation of an international test which has demonstrated its discriminatory ability, further research including replication with both representative samples and special groups should be undertaken.
