Four studies were conducted on a sample of 230 undergraduates to determine the psychometric properties of a measure of alexithymia, the Schalling-Sifneos Scale. In the first study it was found that scores on the scale are approximately normally distributed for each sex with 8.2% of males and 1.8% of females in the alexithymia range. In the second study a factor analysis of the scale revealed three distinct factors: (1) 'difficulty in expression of feelings'; (2) 'the importance of feelings especially about people'; (3) 'day-dreaming or introspection'. In the second factor analytic study, scores from several standard psychological tests on the same subjects were introduced with the scale items. Two factors in this analysis were comprised almost entirely of the other test scores: a 'general psychological distress factor' and a 'concerns about physical symptoms factor'. The other two factors were similar to factors 1 and 2 above in terms of items. The Rathus Assertiveness Scale loaded positively on the equivalent of factor 1. In the lst study, it was shown that Schalling-Sifneos Scale score is relatively orthogonal to other psychological tests with the exception of a Psychosomatic Symptom Checklist and thus is measuring something other than depression, anxiety, etc.
对230名本科生样本进行了四项研究，以确定述情障碍测量工具——沙林-西夫neos量表的心理测量特性。在第一项研究中发现，该量表的得分在每种性别中大致呈正态分布，处于述情障碍范围内的男性占8.2%，女性占1.8%。在第二项研究中，对该量表进行的因素分析揭示了三个不同的因素：（1）“情感表达困难”；（2）“情感的重要性，尤其是关于他人的情感”；（3）“白日梦或内省”。在第二项因素分析研究中，将同一受试者的几项标准心理测试得分与量表项目一起引入。该分析中的两个因素几乎完全由其他测试得分组成：一个“一般心理困扰因素”和一个“对身体症状的关注因素”。另外两个因素在项目方面与上述因素1和因素2相似。拉瑟斯自信量表在相当于因素1的方面呈正负荷。在第一项研究中表明，除了心身症状清单外，沙林-西夫neos量表得分与其他心理测试相对正交，因此它测量的不是抑郁、焦虑等。
