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.

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. Also, they may receive differential therapeutic effects of CBCT and EFCT on different outcomes. Different mediating effects behind the changes in the outcomes will be examined.
