Profile membership was significantly associated with subjective socioeconomic status. Cooperative behavior differed across profiles, with higher levels observed among adolescents embedded in more relationally supportive contexts.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Findings indicate that the pandemic was associated with differences in the distribution of relational profiles rather than a structural reconfiguration of relationship patterns.
