Abstract
Previous research suggests that assessment of mate preferences has received relatively little psychometric attention from researchers, particularly in non-Western cultures. The current research was designed to (1) extend previous findings on long-term mate preferences by using a qualitative strategy, (2) develop a psychometrically sound scale for assessment of long-term mate preferences in men, and (3) develop a sex-neutral scale for assessment of long-term mate preferences. Six dimensions of mate preferences emerged for men: F = family/domesticity, A = attractiveness/sexuality, K = kindness/dependability, E = education/intelligence, R = religiosity/chastity, and S = status/resources. These male-specific dimensions of mate preferences showed satisfactory concurrent and convergent validity as well as high internal consistency coefficients. We mixed the female- and male-specific measures of mate preferences and arrived at 20 characteristics without culture- or sex-specific content. We further hypothesized that the 20-item scale of mate preferences would have a five-factor structure (i.e., kindness/dependability, attractiveness/sexuality, status/resources, education/intelligence, religiosity/chastity [KASER]) in men and women and that this model would replicate sex differences cited in the evolutionary psychological literature. Measurement invariance was evidenced across sexes and sex differences accorded with those in the literature. Therefore, the five-factor model of long-term mate preferences (i.e., KASER model) as measured by the Iranian Mate Preferences Scale-20 may be used to evaluate long-term mate preferences in men and women in Iran. Limitations are noted and future directions are discussed in the light of evolutionary perspective on human mating psychology.
