The data suggest HTR2A A-1438G/T102C polymorphisms may predict negative symptoms performance upon aripiprazole treatment in schizophrenic patients as modified by clinical factors.

The study explores development of the concept of death among 204 Chinese children and adolescents and analyzes the relationships between death concept development and background variables. A coding manual for content analysis of death constructs adapted from R. A. Neimeyer et al. (1983) was used to classify each construct in the paragraphs written by participants regarding their views of death. The 6 categories most frequently identified were Internal Causality, Negative Emotion State, External Causality, Nonexistence, Negative Body State, and Existence. Death-related experiences did not significantly influence concepts regarding death, while significant differences emerged as a function of grade, gender, religion, and family death discussion for several death constructs. Compared with earlier American samples, Chinese children and adolescents identified less with choice and purposeful death constructs and were less likely to view death in terms of personal choice and morals or in terms of psychological or natural meaning. Whether the differences were due to cultural, methodological or age factors deserves further study. Finally, this study concludes with some recommendations for the future study of death constructs.

The purpose of this study was to investigate qualitative and quantitative differences in Chinese children's concepts of death, as reflected in their drawings, and to analyze this conceptual development as it related to background variables (such as gender, age, religious belief, and heath status). Participants were 239 children in 6 grade groups recruited from primary and junior high school. The children were asked to draw their impression of the word "death" and to give a verbal commentary of what they had drawn. The drawings were analyzed according to a phenomenographic method and assigned to one of 3 superordinate and 12 subordinate qualitative categories, adapted from M. E.Tamm and A. Granqvist (1995). Metaphysical and biological death concepts dominated, while psychological death concepts were depicted least. Consistent with previous studies of the development of concepts of death in children, biological death concepts were most common for the younger age groups, and metaphysical death concepts were found predominately in the older age groups. Chi-square analysis revealed no significant differences among death concept categories as a function of the participants' gender, health status, religious belief, funeral attendance, or prior death of relatives or pets. The results are interpreted as providing a unique window on death concepts among Chinese children.
