展示了如何使用定量内容效度程序为初级精神病护理员开发工作相关的行为评定量表标准，通过专家判断和统计分析验证了项目的相关性，并检验了量表的内部一致性和效标关联效度。
This study demonstrated the use of quantitative content validity procedures in the development of a job‐related behavioral rating scale criterion for entry‐level psychiatric aides. Work behavior items were developed by staff from 6 state psychiatric hospitals, placed in a content validity questionnaire using the Lawshe format, and given to a representative sample of 38 aides and supervisors. Seventy‐eight of 83 items were found to be significantly job‐relevant using the computation procedures of both Lawshe and Aiken. After the significant items were grouped into 4 categories with high interjudge agreement and placed in a rating scale format, ratings were obtained on 72 psychiatric aides from 4 hospitals. Items in the 4 categories were found to be internally consistent using coefficient alpha. Significant but low concurrent validities were established for 2 verbal ability selection tests using the rating criterion. The validities found were interpreted to be especially significant when the factors of low selection ratio, restriction in range, and limited rater training were considered.
