Psychometric properties and diagnostic utility of a Brazilian version of the PCL-5 (complete and abbreviated versions).

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.

Screening tools for psychiatry disorders in cancer setting: Caution when using.

This study evaluated sensitivity/specificity of self-report instruments for the screening of psychiatric disorders/symptoms in cancer outpatients like: current/past major depression, dysthymia, alcohol abuse and dependence, tobacco abuse and dependence, panic disorder, social anxiety disorder, generalized anxiety disorder, obsessive compulsive disorder, posttraumatic stress disorder, phobias, current mania, delusion and hallucination. First, 1384 patients responded to several self-assessment instruments. Then, 400 patients, were then interviewed by telephone to confirm the presence/absence of psychiatric diagnosis. The ROC analyses showed moderate/excellent specificity (Patient Health Questionnaire-4 (PHQ-4)=0.75-0.88, Generalized Anxiety Disorder (GAD-7)=0.77, Fast Alcohol Screening Test (FAST)=0.83-0.86, Fagerström Test for Nicotine Dependence (FTND)=0.72, Brief version of the Patient Health Questionnaire-Panic Disorder Module (Brief-PD)=0.75, and Self Reporting Questionnaire - psychosis items=(0.68-0.91) but low sensitivity (PHQ-4=0.53-0.54, GAD-7=0.52, FAST=0.48-0.58, FTND=0.97, and Brief-PD=0.66)). These results suggest that sensitivity indicators should be used with caution in the cancer clinical setting.

[A comparison of consultative psychiatric services in two Brazilian university hospitals using a standardized protocol for recording liaison consultations]. / Comparação entre solicitações psiquiátricas de dois hospitais gerais universitários brasileiros: uso do protocolo de registro de interconsulta em saúde mental.

The objective of the present report was to compare consultative psychiatric services in two Brazilian university hospitals and to evaluate the applicability of a standardized protocol (PRISMe) for recording psychiatric liaison consultations. Analyses of psychiatric consultations and the attached protocol were performed. 541 consecutive liaison consultations were included in the final sample (438 consecutive consultations from the Federal university hospital in São Paulo and 103 from the Federal university hospital in Santa Catarina). In both hospitals, the majority of patients were female, married, white, and 31 to 60 years of age. Depression and adjustment and personality disorders were the most common psychiatric diagnoses, which could explain the higher referral of female patients. The results are consistent with the Brazilian and international literature, and the differences between the two hospitals could be related to both logistical differences between the consultative psychiatric services and the socioeconomic contexts. The findings confirm the applicability of the PRISMe and suggest that systematization of clinical and demographic information is important for future comparative studies.

Comparação entre solicitações psiquiátricas de dois hospitais gerais universitários brasileiros: uso do protocolo de registro de interconsulta em saúde mental / A comparison of consultative psychiatric services in two Brazilian university hospitals using a standardized protocol for recording liaison consultations

O objetivo do presente estudo foi comparar pedidos de interconsulta psiquiátrica realizados para dois hospitais gerais universitários brasileiros e avaliar a aplicabilidade de um protocolo de registro de interconsulta psiquiátrica (PRISMe). Foi realizada análise dos pedidos de interconsulta, do PRISMe anexado a eles e o número total de pedidos de interconsulta incluídos na amostra foi 541 (438 pedidos de interconsulta do HCFMRP-USP e 103 pedidos de interconsulta do HU-UFSC). Observou-se maior freqüência de solicitação para pacientes do sexo feminino, caucasianos, entre 31 a 60 anos e casados. Os diagnósticos psiquiátricos mais freqüentes foram depressão, transtornos de adaptação e de personalidade. Os resultados estão de acordo com a literatura nacional e internacional e as diferenças encontradas podem ser atribuídas às diferenças na infra-estrutura das instituições e nos contextos sócio-econômicos nos quais estão inseridas. Achados do presente estudo demonstram a aplicabilidade do PRISMe e sugerem que podem facilitar a sistematização da obtenção de achados clínico-demográficos e a comparabilidade entre as diferenças.
