Factor structure of the Preschool Personality Questionnaire in Iran

This study is of Triandis's pseudoetic variety, not a cross-cultural study per se. The Preschool Personality Questionnaire which was standardized in the SA and partially standardized in Colombia was administered to 600 preschool children in Iran. Data from the entire sample were analyzed by both principal components, maximum likelihood, and alpha factor analyses. 14 factors were derived. Odd and even records were likewise factored. Six of the first seven factors were found and matched from odd to even cases. At least five of the total sample factors were judged by inspection to match similar dimensions in the USA. Factor scores for children in the standardizing sample were created by postmultiplying the raw score matrix by the 14-factor "reduced" factor structure matrix. These raw factor scores were then converted to STEN scores. Utilizing the entire sample factor structure matrix, factor scores and sten scores were derived for each of the 4-, 5-, and 6-yr.-old groups. By use of the norms based on this sample of Iranian children, further experiments can be carried out to investigate development of preschool children and other variables in Iran similar to those studied in the West.     

The preschool behavioral classification project: An initial report

The Behavioral Classification Project (BCP), previously developed for children from 6–13 years of age, was extended to the preschool ages, the goal being to establish factorial dimensions of problem and nonproblem behaviors of children from 4 to 6 years of age. Initially, behavioral items on the BCP form not applicable to preschoolers were eliminated and replaced with new items. When completed, the Preschool Behavioral Classification Project (PBCP) form contained 268 behavioral items and 5 demographic variables. Forms were administered to 1,350 parents of 4-, 5-, and 6-year-olds, and 668 usable forms were returned. Analysis of the data was done by means of the principal components method in which the data were rotated first to orthogonal simple structure and then to oblique simple structure. Twenty-two clearly delineated factors which made nosological sense were obtained. Five additional factors were extracted and although they were not clearly defined dimensions, they contained important behavioral items.
