This systematic review examined the measurement of suicidal ideation (SI) using smartphone-based ecological momentary assessment (EMA) across 89 studies. It found that 51.7% of SI items were adapted from standardized scales, while over half of the studies distinguished multiple dimensions of SI. The review highlights significant methodological variability and limited psychometric evidence.
Key findings
- 51.7% of SI items were adapted from standardized scales, while 21.3% were custom-developed.
- 57.3% of studies distinguished multiple dimensions of suicidal ideation.
- More than one-third of studies relied on single-item assessments.
- Fifteen studies reported at least one form of psychometric evidence.
Why it matters
Understanding the variability in how suicidal ideation is measured is crucial for clinicians, as it impacts the interpretation of research findings and the development of effective interventions. Improved measurement practices can enhance the reliability of data collected in real-time settings.
