  1. Abstract

    The goal of this study was to examine the relation between real-world socio-emotional measures and neural activation to parental criticism, a salient form of social threat for adolescents. This work could help us understand why heightened neural reactivity to social threat consistently emerges as a risk factor for internalizing psychopathology in youth. We predicted that youth with higher reactivity to parental criticism (vs neutral comments) in the subgenual anterior cingulate cortex (sgACC), amygdala and anterior insula would experience (i) less happiness in daily positive interpersonal situations and (ii) more sadness and anger in daily negative interpersonal situations. Participants (44 youth aged 11–16 years with a history of anxiety) completed a 10-day ecological momentary assessment protocol and a neuroimaging task in which they listened to audio clips of their parents’ criticism and neutral comments. Mixed-effects models tested associations between neural activation to critical (vs neutral) feedback and emotions in interpersonal situations. Youth who exhibited higher activation in the sgACC to parental criticism reported less happiness during daily positive interpersonal situations. No significant neural predictors of negative emotions (e.g. sadness and anger) emerged. These findings provide evidence of real-world correlates of neural reactivity to social threat that may have important clinical implications.

  2. Background

    Suicidal thoughts and behavior can begin early in childhood and are a leading cause of death in youth. Although specific mechanisms of risk remain largely unknown, theorists and researchers highlight the importance of the parent–child relationship. The current study focused on one aspect of this relationship: the dynamic exchange of facial affect during interactions. Specifically, we examined the relation between children's history of suicidal ideation (SI) and synchrony of facial expressions during positive and negative mother–child interactions.

    Methods

    Participants were 353 mother–child dyads. Of these, 44 dyads included a child with an SI history. Dyads engaged in positive and negative discussions during which their facial electromyography was recorded from mothers and children to index second‐to‐second changes in positive (zygomaticus) and negative (corrugator) facial affect.

    Results

    Child SI dyads were characterized specifically by reduced synchrony of positive facial affect during the positive discussion compared to dyads without child SI.

    Conclusions

    These findings suggest child SI dyads exhibit reduced synchrony of normative positive expressions during mother–child interactions. If replicated and extended in longitudinal research, these results may help to explain one mechanism of risk among children with SI.
