Research output: Contribution to journalArticlepeer-review


In this study, a multi-stratified adaptive questionnaire is made of a scale presented by Takei and Ogino (1983). A questionnaire of 6 strata is constructed and administered to about 160 mothers rearing infants aging from 3 to 24 months old. The construction of a questionnaire of adaptive form becomes possible only with appropriate items to be answered by every examinee; it means that a mother does not have to answer the questions obviously too difficult or too easy compared with her baby's ability. The result shows that accuracy of the questionnaire kept high level in spite of the fact that about 2/3 of the items remained unanswered. In addition, it was found that the relationship of chronological ages and the estimated ability levels might be regarded as linear.
