Results of the analysis of mean values, reliability, and factor loadings.

It contains the results of the calculations of the mean, standard deviation (SD), corrected item–total correlation, Cronbach’s alpha and McDonald’s omega reliability coefficients, as well as the factor loadings for all 29 items. Items with factor loadings below 0.40 were eliminated. Subsequently, further analysis was conducted on the remaining 23 valid items. Confirmatory Factor Analysis (CFA) was then performed by treating the variable as unidimensional, as Hills and Argyle (2002) suggest that the Oxford Happiness Questionnaire does not have a stable factor structure and is more appropriately treated as a unidimensional construct.
