Presently, there are no studies focusing on the psychometric properties of PCL-5 in stroke patients, thus our study aimed at solving this problem in the Chinese sample. So, regular psychological assessments using PCL-5 at follow-ups for stroke patients are helpful and deserves wider application. The comorbidity of PTSD is related to stroke patients’ non-adherence of treatment, as well as lower quality of life. Due to the recurrent nature of stroke, long-term medical management is especially important. Annual estimates of 11 million prevalent cases and 2.4 million new cases were reported. Although some studies showed that the degree of disability caused by stroke correlates positively with PTSD symptoms, mild stroke and TIA can also lead to PTSD.Ĭhina bears the biggest stroke burden in the world, and stroke is associated with the highest disability-adjusted life-years lost in this country.

Due to sample heterogeneity, the prevalence of PTSD (or PTSD symptom) varies greatly, ranging from 4 to 37%. Stroke features sudden onset of neurologic deficits and potentially threatens patients’ lives, which kind of medical events is qualified as traumatic events according to the DSM-5 criteria. According to a meta-analysis on post-stroke mood disorder, the prevalence of major depressive disorder, anxiety, dysthymia, and adjustment disorder were 17.7%, 9.8%, 3.1%, and 6.9% respectively. It has subtypes like cerebral infarction, intracerebral hemorrhage, transient ischemic attack (TIA), and subarachnoid hemorrhage (SAH). Stroke is a serious health event and presents one of the leading causes of death and disability in the worldwide. Most previous studies focused on the PTSD secondary to external traumatic events such as combat and sexual violence, while less studies focused on medical conditions or acute illness.

The Chinese version of PCL-5 has been translated and used in traumatized samples. It has been translated to several languages and showed good internal consistency, test–retest reliability, and validity in different samples. Compared to PCL-M/PCL-C/PCL-S which conforms to the DSM-IV criteria, PCL-5 is the only version designed to evaluate the severity of PTSD symptoms across various types of traumas. The PTSD Checklist (PCL) is one of the most frequently used self-report screener for PTSD, and the PCL-5 is the updated version that conforms to the DSM-5 criteria. According to the Statistical Manual of Mental Disorders-version 5 (DSM-5), PTSD is characterized by four clusters of symptoms: recurrent involuntary intrusive memories, avoidance, negative alterations in cognition and mood, and alterations in arousal and reactivity. Post-traumatic stress disorder (PTSD) is a psychiatric disorder which develops as a result of exposure to life-threatening traumatic events. Our findings supported the use of PCL-5 as a psychometrically adequate measure of post-stroke PTSD in the Chinese patients. Receiver operating characteristic (ROC) analyses revealed a PCL-5 score of 37 achieved optimal sensitivity and specificity for detecting PTSD. The PCL-5 also showed good convergent validity and discriminant validity. By CFA analysis, the seven-factor hybrid model demonstrated the best model fit. Exploratory and confirmatory factor analyses indicated acceptable construct validity, and confirmed the multi-dimensionality of the PCL-5.

PCL-5 scores in our sample were positively skewed, suggesting low levels of PTSD symptoms. The cutoff scores, reliability and validity of the PCL-5 were analyzed. They were instructed to complete the PCL-5 scales and were interviewed for PTSD diagnosis with the Clinician Administered PTSD Scale for DSM-5 (CAPS-5). Three hundred and forty-eight Chinese stroke patients came to our hospital for outpatient service were recruited. This was a cross-sectional observational study conducted at our hospital. Our study was conducted to examine the psychometric properties of the PTSD Checklist for DSM-5 (PCL-5) in Chinese stroke patients. Post-stroke PTSD is attracting increasing attention, but there was no study assessing the psychometric properties of the PCL-5 in stroke populations. Stroke is a devastating disease and can be sufficiently traumatic to induce post-traumatic stress disorder (PTSD).
