Authors' conclusion

The IES-R appears to be a useful screening tool for Acute Stress Disorder during hospitalisation and helps clinicians make post-cardiac arrest diagnostic and treatment decisions.

Study context

Population: Survivors of out-of-hospital cardiac arrest (OHCA) who self-reported the Danish Impact of Event-Scale Revised (IES-R); a subset underwent the clinician-rated Acute Stress Disorder Interview during hospitalizationsurvivors who completed the IES-R, out of which 106 completed the Acute Stress Disorder Interview
Participants: 244 survivors

Exposure: IES-R thresholds in classifying probable Acute Stress Disorder, as determined by interview
IES-Rn = 244
Acute Stress Disorder Interviewn = 106
Outcome: Internal consistency and convergent validity of the IES-R

Main finding

As reported in the abstract

Good internal consistency and convergent validity of the IES-R were observed

Observational data: associations, not effects.

Further findings

Classification of probable Acute Stress Disorder by IES-R total cut-off score ≥30 · during hospitalization: 77% · correctly classified · sensitivity 100% · specificity 75%

Classification of probable Acute Stress Disorder by IES-R total cut-off score ≥30: n = 106

Structural validity (factor analysis)

Factor analysis supported the original three-factor structure of the IES-R

Prevalence of probable Acute Stress Disorder using IES-R cut-off ≥30

Prevalence of probable Acute Stress Disorder: 23%

n = 244
