An exploratory factor analysis of t

An exploratory factor analysis of the hyperopia measures revealed a one-factor model fitting our 11 items. It was determined that six items (see the appendix), all with factor loadings of at least .65, would be retained to measure our focal construct. Coefficient alpha provided additional evidence of reliability at .86. These data suggested no relationship between our six-item scale level of hyperopia and one’s general level of self-control as captured in the Tangney et al. (2004) measure (rp .02, NS). Further, an exploratory factor analysis on the six hyperopia items and the 13 self-control items revealed that the hyperopia items all loaded on one factor (loadings ranging from .51 to .78) whereas the 13 self-control items all loaded on a separate factor (loadings ranging from .43 to .73), suggesting that self-control and hyperopia may be distinct personality traits.
