Oral pessimism and depressive symptoms.

I examined the relation of oral optimistic and oral pessimistic personality traits to depressive symptoms to assess the psychoanalytic claim that fixation at the early phase of the oral stage of psychosexual development is related to depression. College students (N = 140) were administered the Oral Optimism Questionnaire (OOQ; Kline, 1978) and Oral Pessimism Questionnaire (OPQ; Kline, 1978) and the Beck Depression Inventory (BDI; Beck, Ward, Mendelsohn, Mock, & Erbaugh, 1961). Oral pessimism and levels of depressive symptoms were positively correlated, and a subsample of subjects with clinical levels of depressive symptoms also scored significantly higher on the Oral Pessimism Questionnaire than the rest of the sample. For the whole sample, 10 BDI items correlated significantly with the OPQ scores, and 5 OPQ items correlated significantly with the total BDI scores. The psychoanalytic claim relating fixation at the oral pessimism stage to depressive symptoms was supported.
