Psychomotor functioning in unipolar and bipolar affective disorders.

The performances of unipolar and bipolar depressive patients and also of a control group on motor, verbal and mental components of psychomotor functioning were clinically and psychometrically evaluated and compared at a univariate and multivariate level. The groups were similar with respect to age, sex, educational level, illness onset age and depression severity. In univariate comparisons of test-based assessments of psychomotor functions the overall tendency was towards a more pronounced retardation in unipolar depressive patients compared to bipolar ones and controls, the differences being marked on some measures and relatively small on others. Multivariate analyses using scores on 20 psychomotor variables revealed a rather good discrimination of the depressive groups, 78.57% of cases being correctly classified, with 0.80 sensitivity for unipolar patients and 0.75 specificity. Clinical evaluation of spontaneous psychomotor activity did not reveal notable differences between the two depressive groups.

Personality traits of psychotic and nonpsychotic depressive patients.

Personality traits of 46 psychotic depressive patients (PD) were compared with those of two matched control groups of nonpsychotic endogenous (NPED) and nonpsychotic nonendogenous (NPNED) depressive patients. Discriminant analyses using personality variables point to more marked differences between PD and NPNED patients than between PD and NPED ones. PD and NPNED groups had opposite traits on the bipolar personality scales of obsessionality vs. hysteria and self-sufficiency vs. group dependence; anxiety, present in both groups, was more pronounced in the NPNED patients. The dependence, introversion and prominent obsessional traits were the distinctive attributes of PD patients when compared with NPED patients. The results are discussed in terms of the two alternative hypotheses concerning psychotic depression: one considering delusions as a function of depression severity and the other as a distinct pathological trait. Our data do not support the exclusive validity of either of these two models.

[Household accidents in an occupationally integrated urban community].

A 42-item questionnaire was used to interview 300 urban residents (working in two chemical plants) who suffered household accidents over the last two years. The main target was to identify the actual causes of these accidents. Findings suggest that accident-producing dysfunctions in the "Man--Non-Professional Environment" system were basically due to particular personal variables such as false mental models of success and lack of risk anticipation from underestimation of task-oriented gestures, prosexis deficit through lack of awareness, rigid work stereotypes and lack of safety constraints. The authors discuss the necessity of a systematic, adaptable educational programme.
