Marital relationship can be a source of trouble. Intimacy issues are often the root cause of failed relationships.

Although some couples may not specifically mention intimacy as a treatment goal, when these same couple’s complete measures of marital quality, satisfaction, or adjustment, they often identify one or more components of the need for intimacy as problematic. The results showed that group couple therapy training based on cognitive-behavioral approach had a significant positive effect on couples' marital satisfaction and increased couples' marital satisfaction.
