Objectives
To assess the prevalence of anxiety, depression and post-traumatic stress disorder (PTSD) and their associated factors among the caregivers of children diagnosed with cancer in Oman and explore the changes in psychological outcomes over time.
Design
A multicentre, prospective, cohort study.
Setting
The National Oncology Centre of the Royal Hospital, the Sultan Qaboos University Hospital and the Sultan Qaboos Comprehensive Cancer Care and Research Centre in Muscat, Oman.
Participants
Caregivers of Omani children and adolescents diagnosed with cancer at the three primary cancer referral centres in Oman.
Outcome measures
Validated Arabic versions of the State-Trait Anxiety Inventory, the Centre for Epidemiologic Studies Depression Scale and the Impact of Event Scale-Revised were used to screen for symptoms of anxiety, depression and PTSD, respectively. The first assessment (T1) was conducted any time within the first 3 months of the child’s diagnosis, while the second assessment (T2) was conducted 3–6 months after T1. Multivariate linear regression models were used to investigate the association between socio-demographic and clinical characteristics and average anxiety, depression and PTSD scores.
Results
Of the 92 caregivers of Omani children and adolescents diagnosed with cancer, 45.7%, 53.3%, 45.7% and 68.5% exhibited state anxiety, trait anxiety, depression and PTSD at T1. Subsequently, prevalence rates of these conditions decreased to 32.6%, 42.4%, 33.7% and 55.4%, respectively, at T2. Between T1 and T2, the prevalence of state anxiety decreased significantly, as did average state anxiety and PTSD scores (p
