The present study examined the psychometric properties of the Schizotypal Ambivalence Scale (SAS) in a sample of 1798 young adults. The study also investigated the concurrent validity of the measure for identifying schizophrenic-like symptoms in a sample of 43 high scorers on the scale and 43 control participants. Previous findings indicated that high scores on the SAS were associated with schizophrenia-spectrum pathology in a sample of schizotypic young adults selected with other measures. However, this is the first study to assess schizophrenic-like psychopathology in a sample selected using the SAS. The SAS has good internal consistency (coefficient alpha = 0.84) and test-retest reliability (intraclass correlation = 0.74 across 9 weeks). As hypothesized, the ambivalence group exceeded the control group on interview ratings of schizotypal, schizoid, paranoid, psychotic-like, and negative symptoms, as well as exhibiting poorer overall functioning. The SAS seems to be a promising measure of schizotypy in young adults.
本研究在1798名年轻成年人样本中检验了分裂型矛盾量表（SAS）的心理测量特性。该研究还在量表得分高的43名参与者和43名对照参与者样本中，调查了该量表在识别类精神分裂症症状方面的同时效度。先前的研究结果表明，在通过其他测量方法选取的分裂型年轻成年人样本中，SAS高分与精神分裂症谱系病理学相关。然而，这是第一项使用SAS选取样本评估类精神分裂症心理病理学的研究。SAS具有良好的内部一致性（α系数 = 0.84）和重测信度（9周内组内相关系数 = 0.74）。正如所假设的，矛盾组在分裂型、类精神分裂症、偏执、类精神病性和阴性症状的访谈评分上超过了对照组，并且整体功能较差。SAS似乎是一种很有前景的年轻成年人分裂型人格测量工具。
