Psychometric properties of the Oxford Happiness Questionnaire Short Form (OHQ-SF) in a Greek student sample

Abstract

BackgroundThe purpose of the current study was to adapt and explore the psychometric properties of the Oxford Happiness Questionnaire Short Form (OHQ-SF) in a Greek student sample.AimThis quantitative cross-sectional study was applied in order to translate and validate the Oxford Happiness Questionnaire Short Form (OHQ-SF) into Greek and to assess the psychometric properties.MethodThe English version of OHQ-SF was translated into Greek using the forward and backward translation. The sample was consisted of 88 adult students from the Public Educational Training Institution in Thessaloniki. Two self-report measures the Greek version of OHQ-SF and the Greek version of the Life Orientation Test Revised (LOT-R—to check the construct validity) were completed twice, for test and retest assessment, in full anonymity and confidentiality.Statistical analysisThe psychometric properties of OHQ-SF/GR, namely the internal–external reliability and construct validity, were assessed, and the expected unidimensional structure was tested with Confirmatory Factor Analysis (CFA).Results and discussionThe Greek version of OHQ-SF (OHQ-SF/GR), for both test and retest, has adequate internal reliability, satisfactory structural validity, and adequate construct validity. The CFA indicated the unidimensional structure of the OHQ-SF/GR, and the fit indexes displayed good fit with the data. One item was removed due to poor correlation with the latent factor of happiness. The current study reveals that the final seven-item OHQ-SF/GR has very satisfactory psychometric properties being useful instrument to measure happiness levels in Greek adult students and is a valid tool that can be utilised in research field.
