A comparison between the Beck's Depression Inventory and the Gotland Male Depression Scale in detecting depression among men visiting a drop-in clinic in primary care.

BACKGROUND: Anger attacks and alcohol use may mask depressive symptoms in men. Only the Gotland Male Depression Scale (GS) includes such items. AIMS: To study the usefulness of the GS and Beck Depression Inventory (BDI) in detecting depression among men in primary care.
METHODS: At a family doctor's drop-in clinic in Stockholm, Sweden, all men were invited into the study 2 days a week (opportunistic screening). On other days, the men who mentioned mental symptoms were invited (targeted screening). The men filled in BDI, GS and a social questionnaire. The doctor invited the men with BDI > or = 10 and /or GS > or = 13 to a repeat visit. The outcome was depression diagnosed according to DSM-IV and the severity was assessed with the Montgomery-Asberg Depression Rating Scale.
RESULTS: 223 men were recruited, 190 by opportunistic and 33 by targeted screening. Seventeen per cent of the men reported an alcohol consumption that might put them at risk. In the opportunistic screening, 23% scored BDI > or = 10 and 14% scored GS > or = 13. The prevalence of depression in the opportunistic screening was 10.5%. The proportion of depressed men in the targeted screening was 60.6%. In total, 40 men were depressed, 63% had a mild and 35% moderate depression. The correlation between the scales was 0.80. The GS identified no additional cases.
CONCLUSIONS: Clinical depression was quite common among those men who often had a high alcohol consumption, indicating an advantage for the GS when screening for depression among men. In primary care, a targeted screening procedure seems to be the most feasible method.
