A 28-Day Ecological Momentary Assessment of Mental Health Among Psychiatric Outpatients With Suicidal Ideation.

The study was conducted during the COVID-19 pandemic, and the planned sample of 128 was reduced to 50, so the findings come from a small group in an unusual period. Only 10 low-risk participants were analysed, so comparisons with the 40 high-risk participants are limited. Suicide attempt history was self-reported and not verified in medical records, so risk-group classification could be wrong. Participants were South Korean psychiatric outpatients with recent suicidal ideation, so the results may not apply to other countries, settings or people without recent suicidal thoughts. The study measured internal mood and stress but did not capture external stressors or factors such as living arrangement, marital status and occupation, so it cannot explain all suicide risk. EMA completion was 76.1%, and some participants gave fewer than three responses on a day, so missing reports may affect the daily patterns. The number of analysed EMA responses is inconsistent between the text and the tables, which makes the data handling harder to check.

The authors declared no conflicts of interest. Funding came from the College of Nursing at Yonsei University and from Korean government research funds, including the National Research Foundation of Korea funded by the Ministry of Education and the Ministry of Science and ICT.

Do not conclude that ecological momentary assessment or remote monitoring prevents suicide. This was an observational study in 50 outpatients, and it did not compare monitoring with usual care or test an intervention.
