Early Prediction of Adolescent Depression (EPAD)

Aims
The Early Prediction of Adolescent Depression (EPAD) Study is a prospective, longitudinal cohort of recurrently depressed parents and their offspring. By tracking families over a decade and documenting their experiences, the study offers in-depth insights into the causes, impacts and resilience factors related to depression. This insight is used to develop evidence-based early intervention and support strategies, as well as to create predictive tools for mental health to ensure targeted support for those most in need. Overall, the study aims to inform national and international understanding and to support affected individuals and their families.

The EPAD Study is also known as the Cardiff University Mood and Wellbeing Study.

Sample details
Families were mainly recruited from general practices in South Wales. Parents were screened over the telephone to confirm they met eligibility criteria for the study at the time of initial recruitment: had a history of at least two prior episodes of major depressive disorder and a biologically related child aged 9-17 years living at home with them. In cases where a parent had two eligible children, the youngest was selected to participate. Families were excluded if the child had a moderate to severe learning disability (IQ less than 50) or if the parent had bipolar disorder or a psychotic disorder at baseline.
