ABSTRACT— The Montgomery-Åsberg Depression Scale was evaluated in 44 depressed inpatients. All items of the scale occurred frequently in the sample; the scale exhibited construct validity (internal homogeneity) and concurrent validity relative to the Hamilton Depression Scale and the concepts of endogenous and nonendogenous depression. Sleep disturbance, reduced appetite, and suicidal thoughts, correlated poorly with the remainder of the scale. Reasons for this finding are discussed. Inter-rater reliability was demonstrated between a psychiatrist and a nurse on individual item and total scale scores.
