A questionnaire made of 71 items was presented to 211 mothers: of these, 119 had their child attending kindergarten (KG group), and 92 a nursery school (NS group); such groups were made in order to investigate the relation between environmental factors, mother's rearing attitude and their child's psychosomatic symptom or behavior, and also to extract some pathological factors from such rearing attitude and environment. Using the following three methods the obtained deta were examined: 1. Comparison between KG group and NS group by each item's average score; 2. Factor analysis for all subjects ; and 3. Comparison between the two groups by factor scores extracting seven factors and testing correlation coefficient into factor scores. The results showed some difference in rearing according to the environment, but no difference in child's psychosomatic symptoms and behavior between the two groups was observed. It was suggested that child's symptoms were caused by their mother' s poor rearing attitude caused by poor rearing environment, for example, a decrease in relations with the neighborhood, etc.
