Pathological affect--impairment of facial expressiveness and demeanor--is a common manifestation of the schizophrenic process. In this study, empirically defined and statistically independent concepts of affectual range, mobility, appropriateness, and communicability were rated by 30 professionals and paraprofessionals from special videotapes of 22 chronic schizophrenics. Reliability of the ratings, measured by correlations among and across parameters and rater types, averaged r = .70, notably better than that of the same raters using traditional subjective clinical judgment (r = .54). There was little disagreement among psychiatrists, psychology interns, junior medical students, or social workers/nurses, nor were any of those groups significantly more reliable than the average for all raters. Significant trends toward low reliability of the appropriateness parameter are pointed out and possible clinical relevance is discussed.
病理性情感——面部表情和举止的损害——是精神分裂症病程的常见表现。在本研究中，30名专业人员和准专业人员根据22名慢性精神分裂症患者的特殊录像带，对情感范围、可动性、恰当性和可交流性等通过实证定义且在统计学上相互独立的概念进行了评分。通过参数之间和评分者类型之间的相关性来衡量，评分的可靠性平均r = 0.70，明显优于同一评分者使用传统主观临床判断时的可靠性（r = 0.54）。精神科医生、心理学实习生、低年级医学生或社会工作者/护士之间几乎没有分歧，而且这些群体中也没有任何一个比所有评分者的平均可靠性显著更高。文中指出了恰当性参数可靠性低的显著趋势，并讨论了其可能的临床相关性。
