RC Checkup demonstrates predictive validity because:

• A. It correlates with short-term mood only.
• B. It has no predictive value.
• C. It only measures communication frequency.
• D. It is linked to long-term relationship outcomes, enabling early identification of at-risk couples.

Answer: (D)

Predictive validity is about how well a measure forecasts what will happen in the future. The RC Checkup has been shown to be linked with long-term relationship outcomes, meaning the scores you get today correlate with how the relationship tends to evolve years down the line. Because of this, it can flag couples who are on a less favorable trajectory early, giving therapists a chance to intervene before problems become more serious. If a measure only related to short-term mood, or claimed no predictive value, or only captured how frequently couples communicate without linking that to future health, it wouldn’t demonstrate the ability to predict long-term relationship success. The real strength here is the observed connection to how relationships fare over time, which supports its use for early identification of at-risk couples.
