Efficient Online Recruitment of Patients With Depressive Symptoms Using Social Media: Cross-Sectional Observational Study

Depression scores also did not vary significantly between groups (U=26,314.500; Z=–.479; P=.63). We observed an increased suicide risk in the online recruitment group (Su Pr-X: U=22,969.500; Z=−3.025; P=.002 and BSS screening: U=23,611.500; Z=–2.323; P=.02) with small effect sizes (Su Pr-X: r=0.140; BSS screening: r=0.108), as reflected in significantly higher scores on Su Pr-X by 1.04 (95% CI 0.41-1.68) points and on BSS screening by 0.53 (95% CI 0.13-0.94) points.
