A Measure to Assess Perceptions and Knowledge About Electroconvulsive Therapy: Development and Psychometric Properties.

OBJECTIVES: Although electroconvulsive therapy (ECT) has been found to be one of the most robust and rapid treatments for severe depression, it is widely underused partly because of negative perceptions and inaccurate knowledge about the treatment. METHODS: The 18-item ECT Perception and Knowledge (ECT-PK) measure was developed through a systematic review of the literature, subject matter expert ratings, and examination of content validity. The ECT-PK consists of Perception and Knowledge subscales, which were tested on a national sample of 1091 US adults who screened positive for depression in 2018 through Amazon's Mechanical Turk platform. RESULTS: Evaluation of the ECT-PK subscales found that both subscales demonstrated good construct validity, criterion validity, and internal consistency reliability. Participants who had higher Perception and Knowledge subscale scores were significantly more likely to report that they were willing to try ECT. The ECT-PK revealed that many participants reported fears about pain, brain damage, and memory loss resulting from ECT, and had inaccurate knowledge about ECT being outdated or lacking scientific evidence. CONCLUSIONS: Together, these results showed that the ECT-PK is an efficient and effective contemporary tool to measure the perception and knowledge of ECT, and highlights areas in need of psychoeducation.

Effects of video psychoeducation on perceptions and knowledge about electroconvulsive therapy.

This study examined the effects of video psychoeducation about electroconvulsive therapy (ECT) on perceptions and knowledge about ECT. A pre-post design was used with a national sample of 1,068 adults who screened positive for depression. Participants' perceptions and knowledge about ECT were assessed before and after watching a psychoeducational video about ECT. Participants showed significant increases in positive perceptions and accurate knowledge about ECT after watching the psychoeducational video. In the perception domain, the items "ECT can be lifesaving" and "fears that ECT can be painful" showed the largest positive increases. In the knowledge domain, items related to "ECT is one of the safest procedures performed" and "ECT can be given safely to older persons" showed the largest increases. Over 20% of participants changed their mind and reported they were willing to try ECT after watching the video. Together, these findings suggest video psychoeducation about ECT holds great potential to improve perceptions and knowledge about ECT, particularly as new technologies are developed to create, distribute, and host videos to reach large audiences.
