ABSTRACT

Objective

The objective of the present systematic review is to answer the following question: is there enough scientific evidence to conclude that virtual reality is an effective tool to evaluate and treat the symptoms of people diagnosed with with schizophrenia?

Background

Eight systematic literature reviews and one meta-analysis focused on this question have recently been published. However, while they tend toward the conclusion that VR is of value in the evaluation and treatment of people diagnosed with schizophrenic disorders, they have important limitations.

Method

We used the PRISMA method. Using the keywords “virtual reality”, “video game”, “schizophrenia”, “therapy” to search in four databases. 31 articles met our selection criteria (with independent double screening). We analyzed the objectives, methods, tools and results of each article.

Results

Twenty of the selected articles provide scientific evidence of the effectiveness of VR for evaluating different domains in schizophrenia. The other eleven articles focus on evidence of therapeutic effectiveness of interventions with VR tools. However, because of the diversity of the dimensions evaluated or treated, and of the VR tools used, replication studies are lacking.

Discussion

There is some scientific evidence that VR tools can be effective in the evaluation and treatment of dimensions of schizophrenia, in particular cognitive dimensions. However, additional studies are needed to confirm these results, replicating measures of the same dimensions using the same VR tools.

用于精神分裂症临床评估和治疗的虚拟现实：系统评价

摘要

客观的

本系统评价的目的是回答以下问题：是否有足够的科学证据表明虚拟现实是评估和治疗精神分裂症患者症状的有效工具？

背景

最近发表了八篇系统的文献综述和一篇聚焦于这个问题的荟萃分析。然而，虽然他们倾向于得出 VR 在诊断和治疗精神分裂症患者方面具有价值的结论，但他们有重要的局限性。

方法

我们使用了 PRISMA 方法。使用关键词“虚拟现实”、“视频游戏”、“精神分裂症”、“治疗”在四个数据库中进行搜索。31 篇文章符合我们的选择标准（独立双重筛选）。我们分析了每篇文章的目标、方法、工具和结果。

结果

二十篇选定的文章提供了 VR 评估精神分裂症不同领域有效性的科学证据。其他 11 篇文章侧重于 VR 工具干预治疗效果的证据。然而，由于评估或处理的维度以及使用的 VR 工具的多样性，缺乏复制研究。

讨论

有一些科学证据表明，VR 工具可以有效地评估和治疗精神分裂症的维度，特别是认知维度。然而，需要更多的研究来证实这些结果，使用相同的 VR 工具复制相同维度的测量。
