This study assessed participant satisfaction with two interpretation formats and the effects of taking the RELATionship Evaluation (RELATE) on single young adults' premarital relationships. Thirty-nine engaged or seriously dating couples were assigned to one of three groups: (a) those who took RELATE and interpreted the results themselves, (b) those who took RELATE and participated in an interpretation session with a therapist, or (c) a control group. Results showed that taking RELATE with therapist assistance had a significant positive effect on perceived relationship satisfaction, commitment, opinions about marriage, feelings about marriage, and readiness for marriage. Positive effects also included increased awareness of strengths and challenges, improved couple communication, and the expectation of the prevention of future relationship problems. Taking RELATE without therapist assistance produced a small initial drop in relationship satisfaction followed by a marked improvement over time. Both genders approved of two interpretation formats-self-interpretation and therapist-assisted interpretation-with males slightly preferring therapist assistance. These results add to the literature on the usefulness of brief assessment techniques as effective interventions with premarital couples.
