This article reports two studies aimed at validating the 25‐item self‐report McGreal and Joseph (1993) Depression–Happiness Scale (D–H S). In the first study, principal component data are reported on the D–H S with 194 respondents. A forced 1‐factor solution confirmed the unidimensionality of the scale (item loadings ranged from .38 to .77) and thus the feasibility of a statistically bipolar measure. In the second study, data on the convergent validity of the D–H S with the Beck Depression Inventory ( r = −.75) and the Oxford Happiness Inventory ( r = .59) with 100 respondents are reported confirming the construct validity of the scale. Implications for research in social and clinical psychology are discussed along with the possible uses of the D–H S in a clinical setting. © 1998 John Wiley & Sons, Inc.
