  • Research summary

    Summary of Research
    Depression in childhood and adolescence occurs in 1–2% of pre-pubertal children and 3–8% of adolescents, with a lifetime prevalence by age 16 of around 10%. Unfortunately, early onset depression is a serious illness: patients are more impaired socially and functionally; their quality of life is poorer; they have a more negative view of life and self, and they have more lifetime depressive episodes, suicide attempts and suicidal ideation. Early-onset depression can be more severe than later onset. However, only approximately one third of patients recover with the first medication prescribed. The slow clinical onset of antidepressant action means that the detection of response or non-response requires 4-6 weeks of drug treatment.
    The P1vital® 'Predicting Response to Depression Treatment' (PReDicT) Test is a set of computer-based cognitive and emotional tasks developed to detect antidepressant response in adults. After 7 days of taking medication, it has been shown to predict response to treatment some 4-6 weeks later. The current study is to see if the PReDicT Test can be modified for use in adolescents- the PReDicT-Adolescent Test (PReDicT-AD Test). The aim is to test how well this test can predict drug response and non-response using data collected approximately 7 days after starting antidepressant treatment in adolescents. With this information we hope to develop for the first time a computer algorithm or formula to predict antidepressant response in this age group.

    Summary of Results
    Unfortunately, recruitment was limited before the COVID pandemic and restrictions made restarting with CAMHS colleagues non-feasible . The study, therefore, had to be stopped. We regret this.
