The Questionnaire in a Sociological Research Project

The reliability and stability of a questionnaire were tested by having 123 eighthgrade children answer it twice with a week's interval by comparing the replies of 62 pairs of siblings, and by comparing the replies of children and mothers. The replies on the two written forms from the same children agreed for 87.3 per cent of the total number of questions. The percentages of agreement varied from 97.6 per cent for factual questions about self to 78.1 per cent for questions on attitudes toward self. For a "neurotic inventory" of 24 questions, 82.7 per cent of the total questions were in agreement on the two forms. The replies of sibblings varied in agreement from 92.5 per cent for factual questions about the parents, to 62.3 per cent for questions involving estimates. Agreement between children and parents was slightly lower. There was no appreciable difference in the percentage of agreement between boys and girls. When certain questions were selected to form a scale to measure home background and were assigned scores, a correlation coefficient of .814 was secured between scores with a week's interval; similar coefficients for the neurotic inventory were .844 for boys and .785 for girls
