Self help books and websites can benefit severely depressed patients
27 Feb 2013
Patients with severe depression show at least as good clinical benefit from ‘low-intensity’ interventions, such as self help books and interactive websites, as less severely ill patients, according to research by The University of Manchester published by the British Medical Journal (BMJ) today.
Depression is a major cause of disability worldwide and effective management of this is a key challenge for health care systems.
The study, funded by the National Institute for Health Research (NIHR), confirmed evidence that ‘low-intensity’ interventions provide significant clinical benefit. Initial severity of depression is one of the key variables determining who gets ‘low’ or ‘high’ intensity treatment, but this is largely based on epidemiological studies and clinical experience rather than high quality evidence.
Researchers from an international collaboration carrid out a meta-analysis of several studies involving 2470 patients with depression, all treated in a non-hospital setting. All studies were from the year 2000 or later with a sample size of more than 50 patients. The mean age in all studies was 35-45, and studies included patients with lower levels of depressive symptoms, as well as those with quite severe depression.
‘Low-intensity’ treatment was defined as interventions designed to help patients manage depressive symptoms such as self-help books or interactive websites, often with limited guidance and support from a health professional. Self-help groups were excluded.
The researchers found that patients with more severe depression at baseline derive “at least as good clinical benefit from ‘low-intensity’ interventions as less severely ill patients”. They recommend including ‘low-intensity’ interventions in the first step of treating severely ill patients and encouraging the majority of patients to use them as the initial treatment option.
Professor Peter Bower, from The University of Manchester who led the research, said: “To better manage depression in the community, many services seek to provide simple forms of psychological therapy (so called ‘low intensity’ interventions) to depressed patients. We assessed whether more severely ill patients demonstrated better or worse treatment effects from ‘low-intensity’ treatments. We found no clinically meaningful differences in treatment effects between more and less severely ill patients receiving ‘low-intensity’ interventions. Patients with more severe depression can be offered ‘low-intensity’ treatments as part of a stepped care model.”
The researchers also say that an important research question for the future is whether low-intensity treatments are cost-effective and if “initial experience with low intensity interventions could act as a barrier to further treatment”.

The National Institute for Health Research (NIHR) is funded by the Department of Health to improve the health and wealth of the nation through research. Since its establishment in April 2006, the NIHR has transformed research in the NHS. It has increased the volume of applied health research for the benefit of patients and the public, driven faster translation of basic science discoveries into tangible benefits for patients and the economy, and developed and supported the people who conduct and contribute to applied health research. The NIHR plays a key role in the Government’s strategy for economic growth, attracting investment by the life-sciences industries through its world-class infrastructure for health research. Together, the NIHR people, programmes, centres of excellence and systems represent the most integrated health research system in the world.
