To determine the psychometric properties of the Spanish versions of the following scales for assessing PTSD patients: TQ, CAPS-DX, DTS, TOP-8, and DGRP.
Data from 63 PTSD patients and 23 healthy subjects were analysed. Internal consistency and test-retest reliability (after 15 days) were calculated. Convergent validity was analysed by correlating subjects' scores with the number of symptoms (DSM-IV) and scores on the CGI scale. Discriminative capability was analysed by comparing TQ, CAPS-DX, DTS, TOP-8, and DGRP patients' scores with scores from healthy subjects, and between patients' subgroups according to the presence or absence of psychiatric comorbidity and to the degree of severity as determined by the CGI-S.
CAPS-DX, DTS, TOP-8, and DGRP showed an adequate internal consistency (Cronbach alpha: 0.74-0.91) and all of them obtained ICC between 0.77 and 0.93. The five questionnaires were able to discriminate between patients and healty subjects, and between the patients' subgroups.
The Spanish versions of the TQ, CAPS-DX, DTS, TOP-8, and DGRP have shown adequate reliability and validity for assessing PTSD patients in daily clinical practice. CAPS-DX seems to be more adequate a diagnostic and DTS a severity rating scale.
确定以下用于评估创伤后应激障碍（PTSD）患者的量表的西班牙语版本的心理测量特性：创伤问卷（TQ）、临床评定量表（CAPS-DX）、解离症状量表（DTS）、创伤后应激障碍快速筛查量表（TOP-8）和创伤相关生长量表（DGRP）。
分析了63例PTSD患者和23名健康受试者的数据。计算了内部一致性和重测信度（15天后）。通过将受试者的分数与症状数量（《精神疾病诊断与统计手册》第四版，DSM-IV）及临床总体印象量表（CGI）得分进行相关性分析来评估收敛效度。通过比较TQ、CAPS-DX、DTS、TOP-8和DGRP患者的得分与健康受试者的得分，以及根据是否存在精神共病和CGI-S确定的严重程度对患者亚组之间进行比较，来分析区分能力。
CAPS-DX、DTS、TOP-8和DGRP显示出足够的内部一致性（克朗巴哈α系数：0.74 - 0.91），并且它们的组内相关系数（ICC）均在0.77至0.93之间。这五个问卷能够区分患者与健康受试者，以及患者亚组之间的差异。
TQ、CAPS-DX、DTS、TOP-8和DGRP的西班牙语版本在日常临床实践中评估PTSD患者时显示出足够的信度和效度。CAPS-DX似乎更适合作为诊断量表，而DTS更适合作为严重程度评定量表。
