About this trial
The goal of this mechanistic clinical trial is to examine whether parent-coaching aimed at increasing child positive affect will increase child neural response to reward. The main questions it aims to answer are:
Aim 1. Characterize child neural reward response and its relation to maternal socialization of positive emotions at baseline in healthy young children.
Aim 2. Evaluate how coaching-related changes in maternal socialization of positive emotion expression contribute to increases in child neural reward response over time.
Aim 3. Examine how maternal socialization of positive emotion expression contributes to increases in child neural reward response in the moment.
Participating mother-child dyads will be randomized to either 3 sessions of parent coaching of child positive affect or 3 sessions of a general parenting support intervention and neural response to reward and affective behavior will be examined pre and post intervention.

Trial outcomes
Primary outcomes
Reward Positivity (RewP)
The Reward Positivity (RewP) ERP component of the EEG signal is the mean amplitude (μV; microvolt) on gain-loss trials during receipt of reward related feedback in a computerized reward task with higher RewP amplitudes indicating greater reward response (i.e., more favorable outcome).
Secondary outcomes
Parent Responses to Child Positive affect Scale (PRCPS)
Change in total score (sum of 7-point Likert scores) on the mother-reported Parent Responses to Child Positive affect Scale (PRCPS) encouragement subscale. The range of possible scores for this outcome is 0 to 84 with higher scores reflecting higher encouragement (i.e., more favorable outcome).
Behavioral Coding of Parental Encouragement of Child Positive Emotion
Parent and child positive emotion will be coded separately on a 0 - 2 scale in 5 second increments. Parental encouragement of child positive emotion will be calculated as the proportion of epochs in which mothers display positive emotion subsequent to child positive emotion expression in the previous epoch. Higher scores indicate greater parental encouragement of child positive emotion (i.e., more favorable outcome).
Late Positive Potential (LPP)
The Late Positive Potential (LPP) ERP component of the EEG signal is the mean amplitude (μV; microvolt) on positive-negative trials during a picture viewing computerized task. Great LPP amplitudes to positive vs. neutral pictures indicate greater response to positive affect (i.e., more favorable outcome).
