摘要
介绍:SAPS 和 SANS 的设计目的是测量两个广泛的因子,但所进行的大多数因子分析都发现了更多的维度。为了研究它们的结构,我们对 SAPS 和 SANS 因子分析进行了元分析:方法:通过数据库搜索(PubMed、PsychINFO)和参考文献搜索,共检索到 42 篇报道 55 项因子分析的文章。从检索到的因子分析中计算出再现相关性,并分别进行了 3 次元分析:对 SAPS SANS 整体评分的荟萃分析(k = 34;n = 5219)得出了一个 3 因子解决方案,包括阳性症状(幻觉和妄想)、阴性症状(情感平淡、嗜睡、逃避/情感淡漠、失乐症/社交障碍和注意力障碍)和组织混乱(阳性形式思维障碍和怪异行为)。SAPS SANS 合并项目分析(k=11;n=3146)发现了 4 个因子,其中消极症状分为情感平淡/自闭和逃避/社交,这是主要差异。仅对 SANS 进行的项目分析(k = 10;n = 2073)发现了 3 个因子,即情感扁平化、逃避/社交性和焦虑/注意力不集中。重要的是,我们的数据表明,"不恰当情感 "和 "言语内容贫乏 "这两个项目应从 "消极症状 "移至 "组织混乱 "因子。注意力障碍在消极症状中的负荷最高,但将其纳入这一维度在概念上并不清晰,最好将其视为一个非特异性领域:积极症状、消极症状和组织混乱的三因子结构涵盖了大部分数据。SAPS SANS总体量表总体有效,但建议对SAPS SANS结构进行保守修订,包括补充子量表。
Meta-analysis of the factor structure of the Scale for the Assessment of Negative Symptoms (SANS) and the Scale for the Assessment of Positive Symptoms (SAPS)
Introduction
The SAPS and SANS was designed to measure two broad factors, but the majority of factor analyses conducted have found substantially more dimensions. To investigate their structure a meta-analysis was conducted of SAPS and SANS factor analysis.
Method
A total of 42 articles reporting 55 factor analyses were retrieved from database searches (PubMed, PsychINFO) supplemented by searches of references. Reproduced correlations were calculated from retrieved factor analyses and 3 separate meta-analyses were conducted.
Results
The meta-analysis of the SAPS SANS global ratings (k = 34; n = 5219) yielded a 3-factor solution including Positive Symptoms (Hallucinations and Delusions), Negative Symptoms (Affective Flattening, Alogia, Avolition/Apathy, Anhedonia/Asociality and Attentional Impairment), and Disorganization (Positive Formal Thought Disorder and Bizarre Behavior). The item analysis of the SAPS SANS combined (k = 11; n = 3146) found 4 factors, with the Negative Symptoms splitting into Affective Flattening/Alogia and Avolition/Asociality as main difference. The SANS only item analysis (k = 10; n = 2073) identified 3 factors, Affective Flattening, Avolition/Asociality, and Alogia/Inattentiveness. Importantly, our data suggests that the items Inappropriate Affect and Poverty of Content of Speech should be moved from Negative Symptoms to the Disorganization factor. Attentional Impairment shows the highest loading on Negative Symptoms but its inclusion under this dimension is conceptually unclear and it may be better considered as a non-specific domain.
Conclusions
The three factor structure of Positive Symptoms, Negative Symptoms and Disorganization accounted for most of the data. The SAPS SANS global scales are generally valid, but suggestions for a conservative revision of SAPS SANS structure, including supplementary subscales, are presented.
期刊介绍:
As official journal of the Schizophrenia International Research Society (SIRS) Schizophrenia Research is THE journal of choice for international researchers and clinicians to share their work with the global schizophrenia research community. More than 6000 institutes have online or print (or both) access to this journal - the largest specialist journal in the field, with the largest readership!
Schizophrenia Research''s time to first decision is as fast as 6 weeks and its publishing speed is as fast as 4 weeks until online publication (corrected proof/Article in Press) after acceptance and 14 weeks from acceptance until publication in a printed issue.
The journal publishes novel papers that really contribute to understanding the biology and treatment of schizophrenic disorders; Schizophrenia Research brings together biological, clinical and psychological research in order to stimulate the synthesis of findings from all disciplines involved in improving patient outcomes in schizophrenia.
