ABSTRACT

Background

The Prodromal Questionnaire (PQ) is a widely used measure for psychosis risk assessment. The primary aim of this study is to examine the reliability and discriminant validity of the Slovak version of the 16-item Prodromal Questionnaire (PQ-16) in a sample of university students.

Methods

A sample of 1276 (75% female) university students completed a cross-sectional online survey consisting of a large battery of scales measuring psychopathology, social functioning, and well-being. The mean age was M = 22.59 and SD = 3.94.

Results

On a bivariate level, the prodromal symptoms severity measured by the PQ-16 was associated with depression, anxiety, lower well-being, and more severe problems in social functioning. The PQ-16 explained a significant variability of social functioning above and beyond the effect of depression and anxiety. Results revealed sufficient internal reliability (α = 0.774 and ω = 0.761) of the scale.

Discussion

The Slovak version of the PQ-16 has sound reliability and shows an adequate pattern of association with depression, anxiety, and social functioning. These promising findings need to be replicated on an independent sample of help-seeking individuals or a high-risk population.

斯洛伐克语版本的 16 项前驱问卷 (PQ-16) 在学生样本中的信度和判别效度

摘要

背景

前驱问卷 (PQ) 是一种广泛使用的精神病风险评估方法。本研究的主要目的是在大学生样本中检验斯洛伐克语版本的 16 项前驱问卷 (PQ-16) 的可靠性和区分效度。

方法

1276 名（75% 为女性）大学生的样本完成了一项横断面在线调查，该调查由大量测量精神病理学、社会功能和幸福感的量表组成。平均年龄为 M = 22.59 和 SD = 3.94。

结果

在双变量水平上，PQ-16 测量的前驱症状严重程度与抑郁、焦虑、较低的幸福感和更严重的社会功能问题有关。PQ-16 解释了社会功能在抑郁和焦虑影响之外的显着变化。结果显示该量表具有足够的内部可靠性（α = 0.774 和 ω = 0.761）。

讨论

斯洛伐克版本的 PQ-16 具有良好的可靠性，并显示出与抑郁、焦虑和社会功能相关的适当模式。这些有希望的发现需要在寻求帮助的个人或高风险人群的独立样本上进行复制。
