The feasibility of a randomized controlled trial (RCT) of a couples therapy program (Contextual Couples Therapy: CCT) targeting Japanese couples has been confirmed.
Furthermore, the intervention program statistically significantly improved relationship quality, and its effects were maintained in follow-up surveys conducted one month and three months after the intervention.

Eighteen heterosexual couples (n = 36) participated in this study. About 97% were married and 3% had lived together for more than seven years but were unmarried. On average, couples were married for 8.51 years (SD = 7.66), and 89% had children (number of children = 1.44, SD = 0.98).
Participants were required to complete an online assessment and subsequent screening via an online video conferencing system.
Participation in this study required both partners to participate, and both partners had to express their willingness to participate and pass the screening.
Couples who passed the screening were randomly assigned to either the intervention group or the waiting list group.
The intervention group participated in three sessions per couple, while the waiting list group waited until the intervention began.
Following this, all participants completed evaluation scales as part of post-intervention and 1-month and 3-month follow-up assessments.
Additionally, couples from the waiting list group subsequently participated in the intervention program on a rolling basis.
No special notes.
The safety and acceptability of the program were good.
An improvement in the Couple Satisfaction Index (CSI) scores was observed in the intervention group.
