Conclusions  Electronic self-monitoring of mood in depression appears to be a valid measure of mood in contrast to self-monitoring of mood in mania .
Background Various paper-based mood charting instruments are used in the monitoring of symptoms in bipolar disorder .
During recent years an increasing number of electronic self-monitoring tools have been developed .
The objectives of this systematic review were 1 ) to evaluate the validity of electronic self-monitoring tools as a method of evaluating mood compared to clinical rating scales for depression and mania and 2 ) to investigate the effect of electronic self-monitoring tools on clinical ly relevant outcomes in bipolar disorder .
There are yet few studies on the effect of  electronic self-monitoring of mood  in bipolar disorder .
Feasibility and acceptability of web-based enhanced relapse prevention for bipolar disorder (ERPonline): trial protocol.
BACKGROUND Relapse prevention interventions for Bipolar Disorder are effective but implementation in routine clinical services is poor . Web-based approaches offer a way to offer easily accessible access to evidence based interventions at low cost , and have been shown to be effective for other mood disorders . METHODS / DESIGN This protocol describes the development and feasibility testing of the ERPonline web-based intervention using a single blind r and omised controlled trial . Data will include the extent to which the site was used , detailed feedback from users about their experiences of the site , reported benefits and costs to mental health and wellbeing of users , and costs and savings to health services . We will gain an estimate of the likely effect size of ERPonline on a range of important outcomes including mood , functioning , quality of life and recovery . We will explore potential mechanisms of change , giving us a greater underst and ing of the underlying processes of change , and consequently how the site could be made more effective . We will be able to determine rates of recruitment and retention , and identify what factors could improve these rates . DISCUSSION The findings will be used to improve the site in accordance with user needs , and inform the design of a large scale evaluation of the clinical and cost effectiveness of ERPonline . They will further contribute to the growing evidence base for web-based interventions design ed to support people with mental health problems
