title: Development of a psychosomatic complaints scale for adolescents.
abstract: There have been only a few questionnaires that can be used to comprehend the psychosomatic complaints of adolescents. Therefore, the objective of the present investigation was to develop a scale for high school students in order to comprehend psychosomatic complaints deriving from psychologic problems. The collection of scale items was performed referring to the health actual situation survey carried out on Japanese school children in the past, and 30 items with a high incidence of psychosomatic complaints were selected out of them and were set as scale items. A survey to assess reliability and validity of the 30 items of the psychosomatic complaint scale was then conducted on the subjects of 759 high school students in total over 3 years. At assessment of validity of the scale, one-factor structure was confirmed by factor analysis and both the eigenvalue and factor loading were found to be at acceptable levels. Further, at assessment of the reliability of the scale, both Cronbach's alpha coefficient indicating internal consistency and the correlation coefficient indicating reproducibility were found to be high. It was concluded that the psychosomatic complaint scale developed in the present investigation was excellent in validity and reliability and was highly practical, having a reduced number of items.
