The interrater reliability of a classification scheme of psychosocial stressors was assessed among 52 child psychiatrists in rating exercises with 28 case histories. Validity was evaluated in a field study of 377 cases rated by 39 of the same child psychiatrists. The impact of glossary descriptions on reliability and validity was also determined. Reliability was low with most Kappa values being in the range of 0.20 to 0.40. The glossary did not affect interrater reliability, but it significantly decreased the use of abnormal codes. The discriminant validity of the codes was supported in that the most commonly used codes were used with differential frequency in a pattern that conforms with the known psychosocial correlates of the different psychiatric conditions of childhood.
在一项评分练习中，52名儿童精神科医生对28份病例史进行评定，以此评估心理社会应激源分类方案的评分者间信度。在一项实地研究中，由39名相同的儿童精神科医生对377例病例进行评定，以此评估效度。还确定了术语表描述对信度和效度的影响。信度较低，大多数卡方值在0.20至0.40范围内。术语表不影响评分者间信度，但显著减少了异常编码的使用。编码的判别效度得到了支持，因为最常用的编码以不同的频率使用，其模式与儿童不同精神疾病已知的心理社会相关因素相符。
