Ambivalence is an important facet of pathology that has received limited attention despite its importance in understanding negative emotionality within schizophrenia spectrum disorders. Central to understanding the role of ambivalence in schizophrenia is characterizing its manifestation within schizotypal individuals-those with the purported genetic liability for schizophrenia. The present study used the Schizotypal Ambivalence Scale (SAS) to examine the nature of ambivalence. An exploratory factor analysis of SAS scores revealed three factors: interpersonal, indecision, and contradictory feelings of ambivalence. Group differences in SAS scores were found such that psychometrically defined schizotypal individuals reported higher levels of ambivalence than controls, and different schizotypy traits exhibited different relationships with SAS factors and quality of life. The inclusion of implicit and explicit measures of positive and negative attitudes revealed that individuals with schizotypy might lack insight into their affective experiences as suggested by the incongruence between our explicit and implicit measures of social attitudes. As hypothesized, the Schizotypal Personality Questionnaire trait dimensions associated with greater SAS ambivalence and the different trait dimensions of schizotypy showed both common and disparate relationships with the ambivalence factors. The current results support the notion that schizotypal ambivalence is a multifaceted construct that not only is affective but also reflects broader processes that dynamically interact with one another to influence functional outcomes.
矛盾情感是病理学的一个重要方面，尽管它在理解精神分裂症谱系障碍中的负面情绪方面具有重要意义，但受到的关注有限。理解矛盾情感在精神分裂症中作用的核心在于描述其在分裂型人格个体（即那些具有精神分裂症假定遗传易感性的个体）中的表现。本研究使用分裂型矛盾情感量表（SAS）来检验矛盾情感的本质。对SAS分数进行的探索性因素分析揭示了三个因素：人际方面、犹豫不决以及矛盾情感的矛盾感受。研究发现SAS分数存在组间差异，即从心理测量学角度定义的分裂型人格个体报告的矛盾情感水平高于对照组，并且不同的分裂型特质与SAS因素及生活质量呈现出不同的关系。纳入对积极和消极态度的内隐和外显测量后发现，正如我们的社会态度外显和内隐测量之间的不一致所表明的那样，分裂型人格个体可能对自己的情感体验缺乏洞察力。正如所假设的那样，与更大的SAS矛盾情感相关的分裂型人格问卷特质维度以及分裂型的不同特质维度与矛盾情感因素呈现出既共同又不同的关系。当前结果支持这样一种观点，即分裂型矛盾情感是一个多方面的结构，它不仅是情感性的，还反映了更广泛的过程，这些过程相互动态作用以影响功能结果。
