Responses to the Pediatric Quality of Life Inventory\u2013version 4 (PedsQL\u20134.0) were collected prior to surgery and 4 to 6 weeks, 3, 6, and 12\u00a0months post-operatively. Latent class growth analyses identified patient subgroups based on their unique trajectories of physical health (PH) and psychosocial health (PSH) outcomes using the PedsQL\u20134.0 subscale scores. Predictors included demographic, clinical, and psychosocial factors.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Data from up to 190 patients were included (87.4% female; mean\u00b1SD age = 14.6 \u00b1 1.9\u00a0years). Three trajectory subgroups were identified for PH and 4 trajectories were found for PSH, with a majority of patients scoring within the established range of healthy adolescents 12\u00a0months post-surgery. Increased child and parent pain catastrophizing, child trait anxiety and previous hospitalizations were associated with poorer PH outcomes, whereas increased child and parent pain catastrophizing, child state and trait anxiety, and parent state and trait anxiety were associated with poorer PSH trajectories.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n
