Psychometric characteristics of the Oxford Happiness Inventory

Psychometric characteristics of the Oxford Happiness Inventory, obtained on various foreign samples, are described. The features of three variants of the Oxford Happiness Inventory are described: the Oxford Happiness Inventory, the full and short forms of the Oxford Happiness Questionnaire. Psychometric indicators of the Oxford Happiness Inventory are presented based on the results of the author's empirical study conducted on a Russian sample. Correlation coefficient between the Oxford Happiness Inventory and two direct questions about happiness from the M. Fordis Happiness Scale r = 0.64 for the entire sample (n = 406), for different age groups: r = 0.68 for students aged 18–24 (n = 156), r = 0.69 for young people 25–34 years old (n = 104), r = 0.63 for adults 35–69 years old (n = 82), r = 0.48 for high school students 15–17 years old (n = 64). Indicators of internal consistency: Cronbach's alpha coefficient 0.91 (n = 406), correlation coefficient between the sum of points: for the first and second half of the questionnaire r = 0.74 (n = 406), for even and odd questions r = 0.79 (n = 406). The retest reliability index for the 6-month interval was r = 0.83 (n = 64). According to the results of this empirical study, the questionnaire can be recommended to a greater extent for diagnosing the subjective psychological well-being and happiness of young people aged 18–35 years, and to a lesser extent — for older and younger age categories. The results of the study complement the limited data on the psychometric indicators of the Oxford Happiness Inventory, as well as the data on the Oxford Happiness Questionnaire, since they have the same questions in terms of meaning.
