|Title:||Completing a postal health questionnaire did not affect anxiety or related measures: randomized controlled trial.|
|Citation:||J CLIN EPIDEMIOL, 2009, 62 (1), pp. 74-80|
|Abstract:||There is evidence from laboratory studies that anxiety scores are elevated by completing questionnaires about health problems for the first time. This limits interpretation of the common finding that people receiving risk information from screening programs show elevated anxiety (as assessed by questionnaire) in the short-term, which subsides over time. We examine the extent to which postal questionnaire studies are affected by this potential measurement artifact.|
