Assessment of the quality of the childhood physical abuse measure in the National Population Health Survey
All respondents to the National Population Health Survey aged 18 or older were asked a question about childhood physical abuse in cycles 1 (1994/1995), 7(2006/2007) and 8 (2008/2009). The reliability of this question was assessed over these periods. Associations between response patterns to the abuse item and health conditions related to childhood physical abuse were examined.
