The effectiveness of an adventure-based marriage enrichment program in increasing marital intimacy was studied. Thirty seven married couples from a relatively conservative Protestant religion composed the sample. The sample was composed of volunteer participants ranging in age from 21-47. The participants were randomly assigned to two treatment groups and a control group. The Waring Intimacy Questionnaire, a participants' Self-Rating of Intimacy Scale, a participants' Intimacy Change Scale, and an open-ended questionnaire were used to collect data. Analysis of Covariance was use to determine differences in post-test scores using the pre-test as the covariate. The findings showed statistical significance for group post-test scores on the WIQ Total Intimacy Scores, E (2,70)= 3.96, p < .05. Significance was shown for group post-test scores on the WIQ cohesiveness subscale, F (2,70) = 8.71, p < .001. / Ph. D.
