Chinese Mothers and Adolescents’ Views of Authority and Autonomy: A Study of Parent–Adolescent Conflict in Urban and Rural China

Eighty‐five dyads of eighth‐grade adolescents (mean age = 14.15 years, SD = 0.39) and their mothers in China (30 dyads from urban one‐child families, 27 from urban multiple‐children families, and 28 from rural multiple‐children families) were interviewed individually. They described daily parent–adolescent conflicts, justified their perspectives on disputes, and evaluated conflict resolutions. The results indicated that across urban and rural areas, for both one‐child and multiple‐children families, adolescents differed significantly from their mothers in their views of parental authority and individual autonomy. The results also showed several regional differences, pointing to the importance of considering the specific context in which conflicts occur.     

Reliability,Dimensionality, and Internal Consistency as Defined by Cronbach: Distinct Albeit Related Concepts

This article uses definitions provided by Cronbach in his seminal paper for coefficient α to show the concepts of reliability, dimensionality, and internal consistency are distinct but interrelated. The article begins with a critique of the definition of reliability and then explores mathematical properties of Cronbach's α. Internal consistency and dimensionality are then discussed as defined by Cronbach. Next, functional relationships are given that relate reliability, internal consistency, and dimensionality. The article ends with a demonstration of the utility of these concepts as defined. It is recommended that reliability, internal consistency, and dimensionality each be quantified with separate indices, but that their interrelatedness be recognized. High levels of unidimensionality and internal consistency are not necessary for reliability as measured by α nor, more importantly, for interpretability of test scores.
