NOTE: This is an unreviewed Preprint
Warning: This is a unreviewed preprint (What is a preprint?). Readers are warned that the document has not been peer-reviewed by expert/patient reviewers or an academic editor, may contain misleading claims, and is likely to undergo changes before final publication, if accepted, or may have been rejected/withdrawn (a note "no longer under consideration" will appear above).
Peer review me: Readers with interest and expertise are encouraged to sign up as peer-reviewer, if the paper is within an open peer-review period (in this case, a "Peer Review Me" button to sign up as reviewer is displayed above). All preprints currently open for review are listed here. Outside of the formal open peer-review period we encourage you to tweet about the preprint.
Citation: Please cite this preprint only for review purposes or for grant applications and CVs (if you are the author).
Final version: If our system detects a final peer-reviewed "version of record" (VoR) published in any journal, a link to that VoR will appear below. Readers are then encourage to cite the VoR instead of this preprint.
Settings: If you are the author, you can login and change the preprint display settings, but the preprint URL/DOI is supposed to be stable and citable, so it should not be removed once posted.
Submit: To post your own preprint, simply submit to any JMIR journal, and choose the appropriate settings to expose your submitted version as preprint.

An Analysis of Iatrogenic Effects in the Evaluation of Suicidal Thought Using Ecological Momentary Assessment in China: Longitudinal Observational Study
ABSTRACT
Background:
In recent years, there has been a significant increase in research using ecological momentary assessment (EMA) to explore suicidal thoughts and behaviors (STBs). Meanwhile, concerns have been raised regarding the potential impacts of frequent and intense STBs assessments on the study participants.
Objective:
This study aims to examine whether intensive repeated assessments of suicidal thoughts increase short-term suicidal risk in Chinese context.
Methods:
From November 2021 to November 2022, a total of 49 patients (age: M = 19.5 years, SD=4.1, range = 12-31 years, 73.5% female), who were with mood disorders and current suicidal ideation were recruited from three psychiatric clinics in China. Smartphone-based EMA was used to measure suicidal thoughts three to six times per day at randomly selected times for four weeks. We examined the change of suicidal thoughts in 28 days and within one day to evaluate potential adverse effects using Bayesian multilevel models.
Results:
The 2691 effective surveys nested in 49 participants (mean following-up days: 23.98 days; average 2.29 times per person per day). The results of both two- and three-level Bayesian cumulative ratio models indicated that suicidal thoughts decreased with an increasing number of surveys in 28 days (β = −0.03, 95% highest density interval (HDI) [−0.05, −0.01]) and within one day (β = −0.26, 95%HDI [−0.50, −0.04]). And this association varied among different individuals in the two-level model (median σ=0.05, 95%HDI [0.03, 0.08]).
Conclusions:
There is no sufficient evidence to suggest that intensive repeated assessments of suicidal thoughts increase the risk of suicide in the short term, but future studies need to carefully consider the heterogeneity of the effects across individuals.
