The current study examined commitment levels of best friend and romantic relationships in both men and women. I hypothesized that women would have higher levels of commitment in best friend relationships than men, but men would have higher levels of commitment in romantic relationships. I also hypothesized that jealousy as an added factor would have a significantly negative correlation with commitment. The sample was composed of 65 adults surveyed via Amazon Mechanical Turk. Each participant was randomly assigned to either the best friend or romantic partner condition. The results of the surveys were then composited in groups—satisfaction, quality of alternatives, investment, and commitment—based on the investment model. The first hypothesis was not supported, and no significance was found between commitment levels between genders. However, the second hypothesis was fully supported; jealousy was significantly negatively correlated with commitment.
