Electroconvulsive therapy (ECT) has been demonstrated by the American Psychiatric Association to be an effective and safe treatment for many psychiatric disorders. (Jaffe, 2001) The use of ECT still generates significant controversy, however. One review concluded that ECT is only marginally more effective than placebo (ie, sham ECT). (Ross, 2006) ECT has been viewed as harmful by the general public, (Lauber, et al., 2005a) psychiatric patients, (Arshad, et al., 2007) and mental health professionals. (Lauber, et al., 2005b)
ECT has also been perceived as a form of violence against women. (Burstow, 2006) It has been negatively portrayed in movies such as One Flew Over the Cuckoo's Nest, House on Haunted Hill, and Requiem for a Dream. (McDonald & Walter, 2001)
Despite such debate, ECT is used in the United States and endorsed by the American Psychiatric Association. (APA, 2015)
