Most research on electroconvulsive therapy (ECT) has focused on technical aspects, such as indications for treatment, efficacy, side effects of treatment, and theories of mechanism of action. Little investigation has been made of the attitudes and experience of patients receiving ECT and less regarding patients' understanding and knowledge of this treatment. Earlier studies have looked at specific aspects of patients' perceptions of ECT, such as subjective side effects, (Gomez, 1975), or the effect of the media on attitudes towards ECT (Bird, 1979). Other studies have investigated these and related issues more comprehensively (Freeman & Kendell, 1980; Hughes et al, 1980). These studies were carried out some time after the ECT course had been completed; in some cases, over a year. It may be that patients' perception and knowledge of ECT are different before and after treatment. Attitudes and knowledge may also change or fade over time.
