Journal Article
Nixon, N., Guo, B., Garland, A., Kaylor-Hughes, C., Nixon, E., & Morriss, R. (2020). The bi-factor structure of the 17-item Hamilton Depression Rating Scale in persistent major depression; dimensional measurement of outcome. PLoS ONE, 15(10), Article e0241370. https://doi.org/10.1371/journal.pone.0241370

Background: The 17-item Hamilton Depression Rating Scale (HDRS17) is used world-wide as an observer-rated measure of depression in randomised controlled trials (RCTs) despite continued uncertainty regarding its factor structure. This study investiga... Read More about The bi-factor structure of the 17-item Hamilton Depression Rating Scale in persistent major depression; dimensional measurement of outcome.

Efficacy and cost-effectiveness of a specialist depression service versus usual specialist mental health care to manage persistent depression: a randomised controlled trial (2016)
Journal Article
Morriss, R., Garland, A., Nixon, N., Guo, B., James, M., Kaylor-Hughes, C., …Dalgleish, T. (2016). Efficacy and cost-effectiveness of a specialist depression service versus usual specialist mental health care to manage persistent depression: a randomised controlled trial. Lancet Psychiatry, 3(9), 821-831. https://doi.org/10.1016/s2215-0366%2816%2930143-2

Background: Persistent moderate or severe unipolar depression is common and expensive to treat. Clinical guidelines recommend combined pharmacotherapy and psychotherapy. Such treatments can take up to 1 year to show an effect, but no trials of suitab...

Clinical and cost-effectiveness of cognitive behavioural therapy as an adjunct to pharmacotherapy for treatment resistant depression in primary care: the CoBalT randomised controlled trial (2014)
Journal Article
Wiles, N., Thomas, L., Abel, A., Barnes, M., Carroll, F., Ridgway, N., …Lewis, G. (2014). Clinical and cost-effectiveness of cognitive behavioural therapy as an adjunct to pharmacotherapy for treatment resistant depression in primary care: the CoBalT randomised controlled trial. Health Technology Assessment, 18(31), 1-167. https://doi.org/10.3310/hta18310

Background: Only one-third of patients with depression respond fully to treatment with antidepressant medication. However, there is little robust evidence to guide the management of those whose symptoms are 'treatment resistant'. Objective: The CoBal...
