The developmental trajectory and predictive factors of prosocial behavior in children with leukemia after illness
Objective To explore the changes and influencing factors of prosocial behavior in chil-dren with leukemia during different stages of treatment,using latent growth curve models and latent class growth models.Methods A total of 120 children with leukemia and their parents were selected as subjects from 2022 to 2023.All the children were evaluated at four assessment time points(diagnosed within 1 week,at the end of 1 month,3 months and 6 months after diagnosed,denoted as T1-T4)using self-designed survey scale,strengths and difficulties questionnaire-prosocial behavior(SDQ-PSB),family closeness scale,and posttraumatic growth inventory.SPSS 23.0 and Mplus 7.4 softwares were used to establish latent growth curve models and latent class growth curve models,and to analyze the trajectory of prosocial behavior and po-tential classes,as well as to explore their influencing factors.Results The SDQ-PSB scores of the children at T1-T4 were(1.24±0.46),(2.79±0.22),(3.88±0.36),and(5.88±0.32),respectively.The total score of SDQ-PSB at T1-T4 showed significant positive correlation(r=0.32-0.79,all P＜0.01).Children with leukemia were divided into two latent classes based on their prosocial behavior:the persistent improve-ment group and the abnormal group.The initial SDQ-PSB scores of the abnormal group were lower than those of the persistent improvement group,and there was no significant change in SDQ-PSB scores over time(slope mean=0.2,P＞0.05).In contrast,the SDQ-PSB scores of the persistent improvement group showed a signifi-cant increase over time(slope mean=0.8,P＜0.001).Children under 7 years old were more likely to belong to the persistent improvement group(B=-0.64,OR=0.62,95％CI=0.15-0.71,P=0.003).Under certain conditions,an increase in family closeness(B=-0.84,OR=0.69,95％CI=0.49-0.72,P=0.003)and en-hanced posttraumatic growth(B=-0.52,OR=0.86,95％CI=0.83-0.95,P=0.025)also led to develop-ment towards the persistent improvement group.Conclusion The trajectory of prosocial behavior develop-ment in children with leukemia after diagnosis is abnormal and marginal,but it shows a significant quadratic upward trend with significant group heterogeneity as the disease progresses.Influencing factors include age,family income,family closeness,and levels of posttraumatic growth.
