Incidence rates of outcomes ranged from 1.6% to 63.6%. The most frequently used predictors were relative's female sex, longer duration of ICU stay, patient's death in the ICU and type of relationship with the patient. Two models reported area under the receiver operating characteristic curve (AUC) values ranging from 0.73 to 0.74; only three models reported calibration, and one study conducted internal validation. Overall, the 17 studies showed good applicability but exhibited a high risk of bias, particularly in data analysis.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Research on predictive models for PTSD risk in family members of ICU patients is in the developmental stage.
