Investigated the relation of 2 components of loneliness, present & future loneliness, to seasonality of suicide attempts. The 110 subjects were persons who attempted suicide during 1 month of a 12 month period. A Loneliness in the Present Scale was devised, and a semantic differential scale was used to measure future loneliness. Seasonally the maximum frequencies of occurrence were in spring & winter. The mean scale scores for present & future loneliness were greatest for spring & winter.
