          ABSTRACT

          Background: With the release of the fifth edition of the Diagnostic and Statistical Manual for Mental Disorders (DSM-5), the Posttraumatic Stress Disorder Checklist (PCL) has been updated to meet the revisions of the diagnostic criteria for Posttraumatic Stress Disorder (PTSD). However, the diagnostic utility and reliability of a Brazilian version of the new Posttraumatic Stress Disorder Checklist (PCL-5) have not been investigated yet.

          Objective: To investigate the internal consistency, test-retest reliability, and diagnostic utility of the complete version (21-item) and two abbreviated (8-item and 4-item) versions of the Brazilian PCL-5.

          Methods: A total of 85 individuals with a history of exposure to at least one traumatic event underwent a diagnostic interview using the Structured Clinical Interview for DSM-5 (SCID-5-CV) and completed the Brazilian version of the PCL-5. Moreover, participants were invited to complete the checklist for a second time 10–30 days after the first assessment.

          Results: Both the complete and abbreviated versions of the Brazilian PCL-5 showed good internal consistency (complete PCL-5, α = .96; 8-item, α = .93; 4-item, α = .85) and test-retest reliability (complete PCL-5, ICC .87 [95% CI, 0.65–0.95]; 8-item, ICC .84 [95% CI, 0.60–0.94]; 4-item, ICC .84 [95% CI, 0.58–0.94]). Diagnostic utility analyses using the Structured Clinical Interview for DSM-5 (SCID-5-CV) revealed that a cutoff point of 36 presented the higher overall efficiency for predicting a PTSD diagnosis Overall Efficiency (OE, .80) and corresponded to Youden’s index J (.65). For the 8-item version, a cutoff point of 13 corresponded to Youden’s index J (.61), while scores of 21 or more were associated with the highest OE (.78). For the 4-item PCL-5, scores > 7 presented the highest OE (.77) and corresponded to Youden’s index J (.59).

          Conclusions: Overall, the findings provide relevant evidence regarding the high reliability and diagnostic utility of this Brazilian version of the PCL-5.

          Antecedentes: con la publicación de la quinta edición del Manual de Diagnóstico y Estadístico para los Trastornos Mentales (DSM-5), el Cuestionario para el Trastorno de Estrés Postraumático (PCL) se ha actualizado para cumplir con las revisiones de los criterios de diagnósticos del trastorno de estrés postraumático (TEPT). Sin embargo, la utilidad diagnóstica y la confiabilidad de una versión brasileña del nuevo cuestionario de trastorno de estrés postraumático (PCL-5) aún no se ha investigado.

          Objetivo: investigar la consistencia interna, la confiabilidad test-retest y la utilidad diagnóstica de la versión completa (21 ítems) y dos versiones abreviadas (8 y 4 ítems) del PCL-5 brasileño.

          Métodos: Un total de 85 individuos con antecedentes de exposición, al menos, a un evento traumático se sometieron a una entrevista diagnóstica utilizando la entrevista clínica estructurada para el DSM-5 (SCID-5-CV) y completaron la versión brasileña del PCL-5. Además, los participantes fueron invitados a completar el cuestionario por segunda vez entre 10 y 30 días después de la primera evaluación.

          Resultados: Tanto la versión completa como las abreviadas de la PCL-5 brasileña mostraron una buena consistencia interna (PCL-5 completa, α = .96; 8 ítem, α = .93; 4-item, α = .85) y confiabilidad test-retest (PCL-5 completa, ICC .87 [IC 95%, .65 - .95]; 8 ítems, ICC .84 [IC 95%, 0.60 - 0.94]; 4 ítems, ICC .84 [IC 95%, 0.58] - 0,94]). Los análisis de utilidad diagnóstica que utilizaron el SCID-5-CV revelaron que un punto de corte de 36 presentó la mayor eficiencia general para predecir un diagnóstico de TEPT (OE, .80) y correspondió al índice J de Youden (.65). Para la versión de 8 ítems, un punto de corte de 13 correspondió al índice J de Youden (.61), mientras que las puntuaciones de 21 o más se asociaron con el OE más alto (.78). Para el PCL-5 de 4 ítems, los puntajes> 7 presentaron el OE más alto (.77) y correspondieron al índice J de Youden (.59).

          Conclusiones: En conjunto, los hallazgos proporcionan evidencia relevante con respecto a la alta confiabilidad y utilidad diagnóstica de esta versión brasileña del PCL-5.

          背景:随着第五版精神障碍诊断和统计手册(DSM-5)的发布,创伤后应激障碍检查表( PCL)已更新,以更新创伤后应激障碍(PTSD)诊断标准的修订。然而,巴西语版本的新创伤后应激障碍检查表(PCL-5)的诊断效用和可靠性尚未得到研究。

          目的:研究巴西PCL-5完整版(21题目)和两个简版(分别有8个题目和4个题目)的内部一致性、重测信度和诊断效用。

          方法:使用DSM-5的结构化临床访谈(SCID-5-CV)对85名有至少一次创伤事件暴露史的个体进行诊断性访谈,并完成巴西版PCL-5。另外,邀请被试在第一次测量后的10-30天内第二次填写检查表。

          结果:巴西PCL-5的完整版和简版均显示出良好的内部一致性(完整版,α = .96; 8题,α = .93; 4题,α = .85)和重测信度(完整版,ICC .87 [95%CI,.65 - .95]; 8题,ICC .84 [95%CI,0.60 - 0.94]; 4题,ICC .84 [95%CI,0.58 - 0.94])。使用SCID-5-CV的诊断效用分析显示,划界分36表现出预测PTSD诊断的总体效率较高(OE,.80),与Youden指数J(.65)相对应。对于8题目版本,划界分13对应于Youden的指数J(.61),而21或更高的得分与最高的OE(.78)相关联。对于4题目PCL-5,得分> 7表示最高的OE(.77)并且对应于Youden的指数J(.59)。

          结论:总体而言,该研究结果提供了有关该巴西版PCL-5的高可靠性和诊断效用的相关证据。

          Psychometric properties of the PTSD Checklist for Diagnostic and Statistical Manual of Mental Disorders-Fifth Edition (PCL-5) in veterans.

          This study examined the psychometric properties of the posttraumatic stress disorder (PTSD) Checklist for Diagnostic and Statistical Manual of Mental Disorders-Fifth Edition (PCL-5; Weathers, Litz, et al., 2013b) in 2 independent samples of veterans receiving care at a Veterans Affairs Medical Center (N = 468). A subsample of these participants (n = 140) was used to define a valid diagnostic cutoff score for the instrument using the Clinician-Administered PTSD Scale for DSM-5 (CAPS-5; Weathers, Blake, et al., 2013) as the reference standard. The PCL-5 test scores demonstrated good internal consistency (α = .96), test-retest reliability (r = .84), and convergent and discriminant validity. Consistent with previous studies (Armour et al., 2015; Liu et al., 2014), confirmatory factor analysis revealed that the data were best explained by a 6-factor anhedonia model and a 7-factor hybrid model. Signal detection analyses using the CAPS-5 revealed that PCL-5 scores of 31 to 33 were optimally efficient for diagnosing PTSD (κ(.5) = .58). Overall, the findings suggest that the PCL-5 is a psychometrically sound instrument that can be used effectively with veterans. Further, by determining a valid cutoff score using the CAPS-5, the PCL-5 can now be used to identify veterans with probable PTSD. However, findings also suggest the need for research to evaluate cluster structure of DSM-5. (PsycINFO Database Record

              Psychometric analysis of the PTSD Checklist-5 (PCL-5) among treatment-seeking military service members.

              The Posttraumatic Stress Disorder Checklist (PCL-5; Weathers et al., 2013) was recently revised to reflect the changed diagnostic criteria for posttraumatic stress disorder (PTSD) in the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5; American Psychiatric Association, 2013). We investigated the psychometric properties of PCL-5 scores in a large cohort (N = 912) of military service members seeking PTSD treatment while stationed in garrison. We examined the internal consistency, convergent and discriminant validity, and DSM-5 factor structure of PCL-5 scores, their sensitivity to clinical change relative to PTSD Symptom Scale-Interview (PSS-I; Foa, Riggs, Dancu, & Rothbaum, 1993) scores, and their diagnostic utility for predicting a PTSD diagnosis based on various measures and scoring rules. PCL-5 scores exhibited high internal consistency. There was strong agreement between the order of hypothesized and observed correlations among PCL-5 and criterion measure scores. The best-fitting structural model was a 7-factor hybrid model (Armour et al., 2015), which demonstrated closer fit than all other models evaluated, including the DSM-5 model. The PCL-5's sensitivity to clinical change, pre- to posttreatment, was comparable with that of the PSS-I. Optimally efficient cut scores for predicting PTSD diagnosis were consistent with prior research with service members (Hoge, Riviere, Wilk, Herrell, & Weathers, 2014). The results indicate that the PCL-5 is a psychometrically sound measure of DSM-5 PTSD symptoms that is useful for identifying provisional PTSD diagnostic status, quantifying PTSD symptom severity, and detecting clinical change over time in PTSD symptoms among service members seeking treatment.
