Factors related to posttraumatic stress in adolescent survivors of childhood cancer and their parents

Goals of work: The purpose of this study was to investigate factors related to severe posttraumatic stress symptoms (PTSS) in adolescent survivors of childhood cancer and their parents. Materials and methods: Eighty-nine families (88 adolescent survivors of childhood cancer, 87 mothers, 72 fathers) completed a self-report questionnaire. Multivariate logistic regression analyses were performed using the following risk factors for severe PTSS: trait anxiety, family functioning, demographic and medical variables. Main results: Severe PTSS were reported by 10.9% (n=9) of the survivors, 20.7% (n=18) of the mothers, and 22.2% (n=16) of the fathers. Preliminary analyses found significant correlations of PTSS between mother-survivor (Spearman's gamma=0.377, p < 0.01) and mother-father (Spearman's gamma=0.483, p < 0.01). The results of multivariate analyses indicated that higher trait anxiety [odds ratio (OR):1.16; 95% confidence interval (CI): 1.03-1.31; p < 0.05] and having medical sequelae (OR: 5.85; 95% CI:1.02-33.72; p < 0.05) were significant factors related to PTSS for survivors. For mothers, the significant PTSS-related factors were: higher trait anxiety (OR:1.13; 95% CI:1.04-1.23; p < 0.01); 5- to 9-year interval from the first diagnosis to the present investigation, compared to more than a 10-year interval (OR: 6.45; 95% CI:1.67-24.89; p < 0.01); and a relatively lower rating on roles of family functioning (OR: 12.34; 95% CI:1.11-136.97; p < 0.05). For fathers, trait anxiety was a significant related factor (OR: 1.07; 95% CI:1.01-1.14; p < 0.05). Conclusions: Survivors and their parents suffered from PTSS after long interval from completion of treatment, and PTSS-related factors varied for each family member. Appropriate allocation of responsibility for family functioning may promote the ability to decrease PTSS, especially for mothers.
