Which statement about the three predictors of the Investment Model of Commitment is true?

• A. Satisfaction, quality of alternatives, and investments
• B. Satisfaction, commitment, and trust
• C. Investments, proximity, and compatibility
• D. Alternatives, opportunities, and communication

Answer: (A)

In this model, commitment in a relationship is predicted by three factors: satisfaction, the perceived quality of alternatives, and the amount of investments already put into the relationship. High satisfaction boosts commitment because you’re content with the relationship. If alternatives look attractive, commitment weakens because another option seems better. Investments—time, energy, shared experiences, plans for the future—tie you to the relationship because leaving would mean losing those resources. The statement that lists satisfaction, quality of alternatives, and investments as the predictors matches this framework precisely, so it’s the best choice. Other options mix in elements that aren’t the model’s three predictors or treat commitment as a predictor itself, which isn’t how the model works.
