THE DEPRESSION-HAPPINESS SCALE - RELIABILITY AND VALIDITY OF A BIPOLAR SELF-REPORT SCALE

This article reports two studies aimed at validating the 26-item self- report McGreal and Joseph (1993) Depression-Happiness Scale (D-H S). i n the first study, principal component data are reported on the D-H S with 194 respondents. A forced 1-factor solution confirmed the unidime nsionality oi the scale (item loadings ranged from .38 to .77) and thu s the feasibility of a statistically bipolar measure. in the second st udy, data on the convergent validity oi the D-H S with the Beck Depres sion Inventory (r = -.75) and the Oxford Happiness Inventory (r = .59) with 100 respondents are reported confirming the construct validity o f the scale. implications for research in social and clinical psycholo gy are discussed along with the possible uses of the D-H S in clinical setting.
