Validity of self-reported prescription drug insurance coverage

Health Rep. 2003 Feb;14(2):35-46.


Objectives: This article assesses the validity of prescription drug insurance coverage as self-reported in the 1996/97 National Population Health Survey (NPHS).

Data source: The data are from the cross-sectional household component of Statistics Canada's 1996/97 NPHS.

Analytical techniques: Most seniors and all social assistance recipients are entitled to prescription drug benefits from their provincial governments. For NPHS respondents eligible for such benefits, the percentage reporting coverage in 1996/97 was calculated. Logit regression was used to assess the determinants of self-reported coverage.

Main results: Only 51% of seniors and 46% of social assistance recipients who were eligible for provincial benefits reported drug insurance coverage in 1996/97. The probability of reporting coverage was generally higher in provinces with drug programs that did not impose deductibles.
