Prevalence and Predictors of the Short-Term Trajectory of Anxiety and Depression in the First Year After a Cancer Diagnosis: A Population-Based Longitudinal Study
A partir des données de deux registres américains des cancers incluant 1 154 survivants, cette étude longitudinale analyse la prévalence et l'évolution des symptômes d'anxiété et de dépression dans l'année suivant le diagnostic
Purpose : Few studies have examined psychological adjustment for cancer survivors in late treatment and early survivorship stages. Our study investigated the prevalence and short-term trajectories of anxiety, depression, and comorbid anxiety-depression among adult cancer survivors, and identified the individual, disease, health behavior, psychological, and social predictors of chronic and late psychological morbidity.
Methods : A heterogeneous sample of adult cancer survivors was recruited from two state-based cancer registries. A total of 1,154 survivors completed self-report questionnaires at 6 (Time 1) and 12 months (Time 2) postdiagnosis. Anxiety and depression were assessed by the Hospital Anxiety and Depression Scale with cases identified by a subscale cutoff score ≥ 8. Logistic regression analyses identified Time 1 characteristics associated with anxiety and/or depression at Time 2.
Results : The point prevalence of anxiety (Time 1, 22%; Time 2, 21%), depression (13% at both timepoints) and comorbid anxiety-depression (9% at both timepoints) was similar at 6 and 12 months postdiagnosis. The most prevalent Time 1 to Time 2 trajectory was noncase for anxiety (70%), depression (82%), and comorbid anxiety-depression (87%). While psychological morbidity at Time 1 was the strongest predictor of psychological morbidity at Time 2, being diagnosed with lung cancer and health risk behaviors (smoking, insufficient physical activity) were also strong predictors.
Conclusion : Targeted psychological screening of vulnerable survivors and early intervention may prevent the onset and/or reduce the severity of psychological morbidity in early survivorship. Trials of risk reduction interventions targeting psychological functioning and health risk behaviors seem warranted.
