title: Investment in Personal Development Scale: a preliminary study.
abstract: Life history theory suggests that reproduction of the species involves three areas of investment: personal development, mating, and nurturing offspring. Using the rational method of test construction, a 29-item scale was constructed to measure investment in personal development, the Investment in Personal Development Scale. Scale scores were statistically significantly correlated with age, year in school, identity commitment, and conscientiousness.
