Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Research question 1:
Is E-CET an efficacious intervention for reducing NEE?
Hypothesis 1:
E-CET will lead to greater reductions in NEE at posttreatment and follow-up compared to BLI.
Research question 2:
Does E-CET work via the violation of the CS-US expectancies?
Hypothesis 2:
Changes in the believability of CS-US expectancies will mediate the treatment effects of E-CET on NEE.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Enhanced Cue Exposure Therapy
This is the experimental arm. Participants will receive the 6-session enhanced cue exposure therapy.
Enhanced Cue Exposure Therapy
The E-CET will consist of six weekly sessions and will be delivered by a clinical psychology trainee in person. Session #1 will be used to introduce to the participant the rationale and procedures of E-CET to establish therapeutic alliance, agreement on treatment goals and tasks, and to collect information on idiosyncratic CS-US expectancies to be targeted in exposures. Sessions #2 to #5 will be in vivo exposures. The interventionist will prompt the participant to evaluate the CS-US expectancy to facilitate the violation of the CS-US expectancy maintaining NEE. Between-session homework exposures will be planned and conducted by the participant in their naturalistic environment. They will also be reviewed at the beginning of the following session to consolidate learning. The final session will consist of consolidation of treatment gains and relapse prevention.
Behavioral Lifestyle Intervention
This is the active control arm. Participants will receive the 6-session behavioral lifestyle intervention.
Behavioral Lifestyle Intervention
The BLI will consist of six weekly sessions of behavioral counselling integrating behavioral strategies for participants to make dietary changes. These behavioral strategies will include education about healthy and balanced diets, goal-setting, problem-solving, and relaxation. A manualized protocol developed by the PI's team for previous studies in the local community will be used.
