study on reliability and validity of the depression-happiness scale in justice's staff of Isfahan city

ABSTRACT

The purpose of this study was to assess the reliability and validity of the Depression-Happiness Scale [H-PS] in staff of Isfahan justice. 200 subjects [134 male, 66 female] with a mean age of 33/7 [ranged from 21to 56] and standard deviation 10/6 were chosen among 900 staff of Isfahan's court. Their literacy level ranged from diploma to MS. All subjects completed the Depression-Happiness Scale [D-HS], Beck Depression Inventory [BDI] and Oxford Happiness Inventory [OHI] in one session. The study of internal consistency of D-HS showed that all items have high correlation with total scores, the Cronbach alpha was 0/93 and test-retest reliability after two months was 0/72. D-HS was highly correlated with OHI and BDI. The factor analysis revealed 5 factors with an eigenvalue greater than 1, which could explain 57/1% of the total variance. But because first factor with an eigenvalue 10/72 accounted for most [42/91%] of the variance, a one-factor model was specified. Depression-Happiness Scale is a reliable and valid test for measuring happiness in Iranian population
