The fears of childhood and adolescence may differ from one cultural context to another. We explored this possibility in 1200 American, Australian, Chinese, and Nigerian children and adolescents between 7 and 17 years of age. Responses to a standard fear survey schedule revealed significant differences in the number, content, pattern, and level of fears. Nigerian children and adolescents endorsed fears at higher levels than American, Australian, or Chinese youth who did not differ from one another. However, differences in the pattern and content of fears for boys and girls of different ages were noted across the countries. Results were interpreted within a cultural context, which suggested that cultures which favor inhibition, compliance, and obedience serve to increase levels of fear. Alternative interpretations are offered and limitations of cross-cultural research are explored.
