Our decision to retain an item as part of a given factor was based on two criteria: the factor loading for that item had to be ≥ 0.4 (i.e. account for approximately 16% or more of the explained variance in that factor), and the item could not load on another factor within ±0.1. According to Ho, et al. (2001), the minimally acceptable coefficient is 0.33 because the squared proportion accounts for at least 10% of the variance in a given factor. We dropped one item from factor 4 (item 37) because it loaded within 0.1 on factor 5. We retained the remaining 23 items for further analysis.
