Selecting items for Big Five questionnaires: At what sample size do factor loadings stabilize?
نویسندگان
چکیده
Researchers often use exploratory factor analysis (EFA) to develop and refine questionnaires assessing the Big Five personality traits. We use sequential sampling and bootstrapping to determine the number of participants needed to yield stable loading patterns for the Big Five Inventory (BFI) and the International Personality Item Pool Big Five measure (IPIP). Overall 21,350 participants (BFI = 10,285; IPIP = 11,065) participated. In two studies primary factor loadings are highly variable in smaller samples (n < 500) and some primary loadings are not stable with 10,000 participants. Most studies will not have adequate sample size to yield stable loading patterns for Big Five measures such as the BFI and IPIP. Researchers should assess and report the variability of loading patterns.

Six personality factors, including five resembling the human Big Five, had previously been identified in a separate group of zoo-housed chimpanzees. Comparability of chimpanzee personality factor structure was examined in two highly contrasting habitats: zoos and a large African sanctuary. Questionnaires for the zoo chimpanzees were in English, while most for the chimpanzees in the sanctuary we...

Exploratory factor analysis (EFA) is generally regarded as a technique for large sample sizes (N), with N = 50 as a reasonable absolute minimum. This study offers a comprehensive overview of the conditions in which EFA can yield good quality results for N below 50. Simulations were carried out to estimate the minimum required N for different levels of loadings (λ), number of factors (f), and nu...
