New approaches to the ‘crucial’ test of the causation and selection hypotheses in a Northern Irish sample

This paper examines the relationship between minority/majority status and psychological adjustment, as measured by the GHQ‐12. Rather than using religious labels in Northern Ireland to define minority/majority status, the authors hypothesized that such status is more contingent upon the local area context. Using a purer operationalization of minority/majority status, the authors found no evidence of an ‘ethnic density effect’. Implications for the questionable validity of the ‘crucial test’ of the selection and causation hypotheses are discussed. Copyright © 2002 John Wiley & Sons, Ltd.
