  • Objective: This study aimed to review scales and tests developed for or validated with children and their families that were published in the Korean Journal of Child Studies from 1984 to 2016. Specifically, the purpose of the present study was to analyze the contents and format of the selected instruments, as well as to evaluate their psychometric properties. Methods: Using several databases and journal archives from the Korean Journal of Child Studies, searches were implemented using the key terms: instrument, scale, development, and validation. Instruments from 76 selected studies were reviewed based on several characteristics, such as assessment areas, contents, respondents, responding types, and psychometric properties. Results and Conclusion: First, a majority of the reviewed instruments were developed for infants and children, whereas only one was developed for adolescents. With regard to their specific measurement domains, many instruments focused on social emotional development among children. Second, with a few exceptions, the selected studies provided appropriate evidence for the reliability of the instrument, including its internal consistency, inter-rater reliability, and spilt-half reliability. Many studies also reported on the criterion-related or construct validity of the instrument to establish its validity. Future studies need to develop instruments across diverse developmental areas that collect information from multiple sources and raters. In addition, more evidence on the reliability and validity of the reviewed instruments should be provided to demonstrate their psychometric qualities.

  • With the high prevalence of functional dyspepsia in the world, it was difficult to get objective diagnosis, treatment and assessment for the reason that there were many different symptoms and signs. The purpose of this study is to develop a standard instrument of pattern identification for functional dyspepsia which will be applied to clinical research. The items and structure of the instrument were based on review of published literature. The advisor committee on this study was organized by 11 oriental division of gastroenterology professors of oriental medical colleges nationwide. The experts discussed developing the instrument, and we also took professional advices by e-mail. We divided the symptoms and signs of functional dyspepsia into 6 pattern identification, such as disharmony of liver and stomach, retention of undigested food, damp-heat in the spleen and stomach, simultaneous occurrence of cold and heat syndromes, deficiency and cold of the spleen and the stomach, and insufficiency of stomach eum. We got the mean weights to each symptom of six pattern identification which had been scored on a 5-point scale ranging from 1 to 5 by the 11 experts. We made out the Korean instrument of the pattern identification composed of 45 questions for functional dyspepsia. Although there are some limitations in our study, the instrument is meaningful and certain worth of its own. We hope to improve the instrument through the further clinical studies and discussions.
