Chinese high school students family support function scale (CHSS-FSFS) was developed based on standard procedures for scale development: conceptual model, building initial item pool based on literature review, item selection, and modification using consumer and expert panels and item reduction methods. A combination of qualitative and quantitative scale development techniques, as well as the involvement of consumers, was used in order to enhance the content validity of this scale. Family has already been extensively recognized to be one of the key factors in adolescent development. However, previous research has shown that quite a few parents did not provide adolescents with necessary support in China. In addition, this lack of support was found to be related to a lack of knowledge about adolescent’s needs for family. Although more than 20 related tools have been developed in different countries, cultural differences and length of administration prevent their application in China, as well as none of these tools were developed specifically for high school students. The purpose of this study was to develop a brief family support function scale for Chinese high school students (FSFS-CHSS). Standard procedures for scale development were used to develop a 17-item scale. Families of students in 96 high school classes in Hunan were used for item selection and validation. Tables, references
