Background: Research suggests that screening for suicidality does not have iatrogenic effects; however, less is known regarding the impact of repeatedly screening for suicidal ideation among individuals with varying levels of exposure to these screenings. This staggered sequential study evaluated whether suicidal ideation severity increases with repeated screening for suicidal ideation and depression symptoms.
Methods: Undergraduates (N = 207) were recruited at one of four time points (baseline [n = 37], 1 month later [n = 61], 4 months later [n = 55], and 12 months later [n = 54]) to complete the self-report Beck Depression Inventory (BDI). Participants completed the BDI at the time point at which they were recruited and all subsequent study time points. Non-parametric tests were employed to compare suicidal ideation severity (BDI Item 9) and depression symptom severity (BDI total score): (1) within each group across time points and (2) within each time point across groups.
Results: Suicidal ideation severity did not significantly differ within any group across time points, and for two groups, depression symptom severity decreased over time. For analyses between groups, suicidal ideation and depression symptom scores were, at times, significantly lower during subsequent BDI completion time points.
Limitations: This study utilized a relatively small sample size and participants of low clinical severity.
Conclusions: Findings align with prior research indicating that suicidality screening is not iatrogenic. This study also expanded upon previous studies by leveraging a staggered sequential design to compare suicidal ideation and depression symptom severity among individuals with varying exposure to suicidal ideation screenings.
