For a sample of 81 infants whose temperament were investigated at 5-8 months and 2 infants who wanted to participate in this research, assesment of temperament by Toddler Temperament Questionnaire (TTQ) was obtained at 12-15 months of age. The item reliability was acceptable, and 9 temperamental categories were divided into four factors. Factor Ⅰ consisted of rhythmicity, adaptability, and mood, factor Ⅱ of approach and threshold, factor Ⅲ of activity, persistence, and distractibility, and factor Ⅳ of intensity.
There were moderate stability of temperamental characteristics across 5-8 and 12-15 months. Of the 9 temperamental categories, 6 categories (rhythmicity, approach, adaptability, mood, intensity, and persistence) showed significant relations between the two research period. And fifty-three percent of the infants still remain in the same diagnostic groups during the 7-months intervals. The result of this study demonstrated the utility of TTQ and the validity of temperament assessment.
