Abstract

Objective

To investigate scale-level and especially item-level correlates of the Psychiatric Diagnostic Screening Questionnaire (PDSQ) with an emphasis on its clinical usefulness in primary care settings. In addition, gender-based correlate differences were explored to test whether gender-specific conclusions were warranted. Overall, the current empirical correlates sought to improve the PDSQ's precision in clinical interpretations.

Method

The current dataset was composed of 234 primary care patients, systematically evaluated via the Structured Clinical Interview for DSM-5 Disorders-Research Version (SCID-5-RV) for 10 common mental disorders. Rather than using the typical skip-out logic, the 10 modules were administered in their entirety, providing item-level correlates for the PDSQ as the index measure.

Results

When adequately represented (n ≥ 10), PDSQ subscales produced strong scale homogeneities (M alpha = 0.85). At the item level, they evidenced strong convergent validities (M r = 0.64), clearly more than doubled their discriminant validities (M r = 0.25). Adopting a stringent criterion (r ≥ 0.35), 273 PDSQ empirical correlates were established for common diagnoses. Regarding gender, seven disorders produced similar scale correlates, whereas three were divergent.

Conclusion

As the third independent investigation, PDSQ item-level correlates have been empirically validated in both psychiatric and primary care settings. The PDSQ, in its expanded role, provided valuable clinical data regarding DSM-5 symptoms and clinical characteristics.

Summary

Consistent with the first objective, the PDSQ subscales demonstrated excellent internal consistency and construct validity.
For specific symptoms and clinical characteristics, the PDSQ is distinguished from most self-report psychological measures regarding the precision of its clinical findings via item-level correlates.
In the context of the replication crisis, rigorous criteria were applied to bivariate correlates, ranging from moderate (rs ≥ 0.35) to very large (rs ≥ 0.60) for each PDSQ subscale.

精神病诊断筛选问卷（PDSQ）：心理测量特性与项目水平的经验相关性

目的探讨精神病学诊断筛查问卷（PDSQ）的量表水平，特别是项目水平的相关因素，重点研究其在初级保健机构的临床应用。此外，还探讨了基于性别的相关差异，以检验是否有必要得出针对性别的结论。总的来说，目前的经验相关性试图提高PDSQ在临床解释中的准确性。方法当前数据集由234名初级保健患者组成，通过DSM-5障碍研究版（SCID-5-RV）的结构化临床访谈对10种常见精神障碍进行系统评估。而不是使用典型的跳过逻辑，这10个模块被完整地管理，为PDSQ提供项目级别的相关性作为索引度量。当充分代表（n≥10）时，PDSQ亚量表产生了很强的量表均匀性（M α = 0.85）。在项目水平上，它们表现出较强的收敛效度（M r = 0.64），明显是其判别效度的两倍多（M r = 0.25）。采用严格的标准（r≥0.35），建立了273个常见诊断的PDSQ经验相关性。在性别方面，7种疾病产生了相似的量表相关性，而3种是不同的。结论作为第三项独立调查，PDSQ项目水平的相关性在精神科和初级保健机构中都得到了实证验证。PDSQ在其扩展的作用下，提供了有关DSM-5症状和临床特征的宝贵临床数据。与第一个目标一致，PDSQ子量表表现出良好的内部一致性和结构效度。对于特定的症状和临床特征，PDSQ与大多数自我报告心理测量的区别在于，它通过项目水平的相关性来确定临床结果的准确性。在复制危机的背景下，严格的标准应用于双变量相关，从中等（rs≥0.35）到非常大（rs≥0.60）的每个PDSQ子量表。

期刊介绍： Clinical Psychology & Psychotherapy aims to keep clinical psychologists and psychotherapists up to date with new developments in their fields. The Journal will provide an integrative impetus both between theory and practice and between different orientations within clinical psychology and psychotherapy. Clinical Psychology & Psychotherapy will be a forum in which practitioners can present their wealth of expertise and innovations in order to make these available to a wider audience. Equally, the Journal will contain reports from researchers who want to address a larger clinical audience with clinically relevant issues and clinically valid research.
