Detailed Description
This study will test the effects of a dyadic preventive intervention, Family Promoting Positive Emotion (F-PPE), for 8- to 12-year-old children of mothers with a history of major depressive disorder (MDD) with anhedonia. The study will first test F-PPE effects on child reward responsiveness (R61), and pending evidence of target engagement, effects on real-world experience of interest/pleasure and clinical symptoms of anhedonia will be evaluated in a second, larger clinical trial (R33). F-PPE was designed to increase child positive valence systems function through mother-child training in behavioral and cognitive skills to increase pleasant activities and attention towards/savoring the positive, individual and dyadic goals, and skills practice. For the R61 phase, eligible child participants (N=60 intervention completers) will complete an EEG assessment of neural reward responsiveness, as well as halfway through the intervention (4 weeks) to determine dose effects. Children and their biological mothers will be randomly assigned to 8 sessions of F-PPE or a psychoeducation comparison condition (groups will be matched on child sex and baseline RewP). Both interventions will be administered through individual telehealth sessions with a masters- or doctoral-level clinician under the supervision of the PIs. To ensure treatment fidelity, videotaped sessions will be reviewed for adherence to the protocol, clinicians will participate in weekly group supervision, and supervisors will randomly review recorded sessions for ratings of treatment adherence.

Outcome Measures
Primary Outcome Measures
- Neural responses to rewards measured by electroencephalogram (EEG) in a computerized guessing reward task (physiological measure) [4 and 8 weeks]
The reward positivity (RewP) component will be measured using EEG with an established computerized guessing reward task ("Doors" task). EEG data will be processed using best practices and the RewP component will be exported from the EEG data approximately 250-350 ms after feedback presentation at the electrode Cz. RewP scores will be quantified as the relative neural response to reward vs. loss feedback.
