Using the California Q-sort Measure of Life History Strategy to Predict Sexual Behavioral Outcomes

The validity of the California Q-set measure of life history (LH) strategy was examined by conducting secondary analyses on longitudinal data that included the Q-sort measure of LH strategy at multiple ages (base year N = 106) and six measures of reproductive behavior. LH strategy Q-sort ratings showed stability from ages 14–23. Additionally, the ratings were found to be good prospective and age concurrent predictors of six reproductive behaviors. LH strategy as rated at age 14 was found to be a significant predictor of age of sexual debut, number of sexual partners, frequency of intercourse, number of abortions, age at birth of first child, and likelihood for having contracted venereal disease as measured up to age 32. Future research should test the further utility of the measure focusing on ways to reduce its cumbersomeness without reducing its ability to predict behavioral outcomes.
