Internal consistency, reliability, and temporal stability of the Oxford Happiness Questionnaire short-form: Test-retest data over two weeks

Abstract

The Oxford Happiness Questionnaire short-form is a recently developed eight-item measure of happiness. This study evaluated the internal consistency reliability and test-retest reliability of the Oxford Happiness Questionnaire short-form among 55 Northern Irish undergraduate university students who completed the measure on two occasions separated by two weeks. Internal consistency of the measure on both occasions was satisfactory at both Time 1 (alpha = .62) and Time 2 (alpha = .58). Stability across the two administrations was satisfactory (r = .69), and there was no significant change between Time 1 (M = 34.5, SD = 5.4) and Time 2 (M = 34.6, SD = 5.2). These data support the internal consistency reliability and short-term test-retest reliability of the Oxford Happiness Questionnaire short-form.
