Exploring the self in adolescent depression: neural mechanisms underlying social evaluations and self-views from a parent-adolescent perspective

Houtum, L.A.E.M. van

This dissertation focuses on identifying neural mechanisms underlying social evaluations and self-views from a parent-adolescent perspective among adolescents with and without depression, and their parents. As part of RE-PAIR, affective and neural responses to praise and criticism about the adolescent child, and neural responses to reliving positive autobiographical memories were assessed, using ecologically valid fMRI-tasks. Particularly criticism seems to be highly salient to parents and adolescents, activating the salience network and decreasing mood. Both praise and reliving positive autobiographical memories activate areas important for self-referential processing in adolescents, which might reflect the ‘positive self’. Aberrant self-related processing when reliving autobiographical memories and increased sensitivity to parental criticism might be key underlying neural mechanisms in adolescent depression. By feeling more negatively, having more negative self-views,...Show moreThis dissertation focuses on identifying neural mechanisms underlying social evaluations and self-views from a parent-adolescent perspective among adolescents with and without depression, and their parents.

Both praise and reliving positive autobiographical memories activate areas important for self-referential processing in adolescents, which might reflect the ‘positive self’. Aberrant self-related processing when reliving autobiographical memories and increased sensitivity to parental criticism might be key underlying neural mechanisms in adolescent depression. By feeling more negatively, having more negative self-views, interpreting the environment as more negatively, memorizing past experiences in a more negative way, and focusing on negative events more often, adolescents with depression seem to have multiple negativity biases. These negativity biases are likely to negatively impact social relationships, potentially further reinforcing negative feelings and a negative self. Interventions exploring and strengthening the positive self, in particular the positive self aligning with the current self, might be useful for treating, or even preventing adolescent depression.
