Brief Summary

Understanding depression from a relational perspective maybe more meaningful in Chinese culture due to the different values and beliefs among Chinese comparing to those of the Western cultures. The PI and his associates developed a Cognitive Behavioural Couple Therapy model for Chinese couples with a depressed partner receiving mental health services in a community mental health centre in Hong Kong between 2018 and 2019. With consideration of the limitations in a pilot study conducted by the PI, modifications are made in the current study. This study aims to evaluate the effectiveness of a cognitive behavioural couple therapy model for Chinese couples with a depressed partner in Hong Kong. A comparison approach involving cognitive behavioural couple therapy (CBCT), emotional focused couple therapy (EFCT) and a wait-list control group on their short-term and long-term effects, as well as differential benefits will be examined.

A set of questionnaires will be filled out by the 135 participants (45 in each arm) before the intervention (T0), after the intervention (T1), and 6-month after the intervention (T2). It is hypothesized that comparing to the control group, participants in CBCT and EFCT conditions will have greater improvements in outcomes at T1 and T2. There will be differential therapeutic effects of CBCT and EFCT on the various outcomes. Different mediating effects behind the changes in the outcomes in the two conditions will be examined.

The study will contribute to the current literature by evaluating the effectiveness of culturally-attuned CBCT and EFCT. New insights will be added to the current therapeutic approaches for couples with a depressed partner.

Primary Outcome Measures

Name	Time	Method
Change from Baseline Patient Health Questionnaire-9 at 2 months (post-intervention) and 8 months (6 months after intervention)	Day 0 (Baseline), Month 2 (Post-intervention), Month 8 (6-month follow-up)	To assess frequency of depressive symptoms of the participants during the preceding 2 weeks. The 9 items are rated on a 3-point scale from 0 (not at all) to 3 (nearly every day). The range of the scale is 0 to 27. Higher scores indicated more depressive symptoms.
Change from Baseline Depression Anxiety Stress Scales-Chinese Version at 2 months (post-intervention) and 8 months (6 months after intervention)	Day 0 (Baseline), Month 2 (Post-intervention), Month 8 (6-month follow-up)	To assess the emotional states of depression, anxiety and stress in the participants. The 21 items are rated on a 4-point scale from 0 (not applicable) to 3 (very applicable). Sum scores are computed by adding up the scores of each item and then multiplying by 2. The range of the scale is from 0 to 120. Higher scores indicated higher levels of depression, anxiety and stress.

Secondary Outcome Measures

Name	Time	Method
Change from Baseline Marital Satisfaction with Life Scale at 2 months (post-intervention) and 8 months (6 months after intervention)	Day 0 (Baseline), Month 2 (Post-intervention), Month 8 (6-month follow-up)	To measure the subjective evaluation of one's satisfaction in life. The 5 items are rated on a 7-point scale from 1(strongly disagree) to 7(strongly agree). The range of the scale is 5 to 35. Higher scores represent greater life satisfaction.
Change from Baseline Dyadic Adjustment Scale at 2 months (post-intervention) and 8 months (6 months after intervention)	Day 0 (Baseline), Month 2 (Post-intervention), Month 8 (6-month follow-up)	To evaluate 4 dimensions of marital quality of the participants (Consensus, Cohesion, Satisfaction and Affectional Expression). The range of the scale is 0 to 151. Lower total scores indicate greater distress in marital relationships.; The 15 items of Consensus are rated on a 6-point scale from 0 (totally agree) to 5 (totally disagree). Two of the 6 items of Cohesion are rated on a 5-point scale from 0 (daily/all) to 4 (never) while the remaining 4 items on a 6-point scale from 0 (never) to 5 (always). Seven of the 9 items of Satisfaction are rated on a 6-point scale from 0 (anytime) to 5 (never) while one of the remaining items asked the participants to describe their marriage from 7 choices from "extremely unhappy" to "perfect". The last item included 6 sentences about views on the marital relationships and the participants are asked to choose the best one describing their thoughts. The 2 items of Affectional Expression are answered by "yes" or "no".
Change from Baseline Difficulties in Emotion Regulation Scale-Short Form at 2 months (post-intervention) and 8 months (6 months after intervention)	Day 0 (Baseline), Month 2 (Post-intervention), Month 8 (6-month follow-up)	To assess individuals' emotion dysregulation patterns. The 18 items are rated on a 5-point scale from 1 (almost never) to 5 (almost always). The range of the scale is 18 to 90. Higher scores indicate greater emotion dysregulation.
Change from Baseline Relationship Belief Inventory at 2 months (post-intervention) and 8 months (6 months after intervention)	Day 0 (Baseline), Month 2 (Post-intervention), Month 8 (6-month follow-up)	To measure unrealistic beliefs about marriage of the participants. The 40 items are rated on 6-point scale from 0 (strongly believe the statement is false) to 5 (strongly believe the statement is true). The range of the scale is 0 to 200.
