Differential susceptibility to peer rejection and acceptance: A within-child experiment

= 10.86, 49.5% boys) to receive either counterbalanced rejection and acceptance feedback (experimental group) or neutral feedback (control group) from online fictitious peers, and assessed their emotional, self-esteem, attributional, and behavioral responses. Results revealed two subgroups of children showing elevated emotional or self-esteem reactivity to both rejection and acceptance, supporting within-child differential susceptibility. However, SPS did not distinguish these subgroups or moderate children's responses to peer feedback - suggesting limited support for SPS as a differential susceptibility marker to experimentally manipulated peer acceptance and rejection.
