Climatic factors and bipolar affective disorder.

In bipolar disorder, the factors provoking a new episode are unknown. As a seasonal variation has been noticed, it has been suggested that weather conditions may play a role. The aim of the study was to elucidate whether meteorological parameters influence the development of new bipolar phases.

Life events and onset of a new phase in bipolar affective disorder.

Background: There is an increasing focus on the impact of psychosocial factors and stressors on the course of bipolar affective disorder. The life event research has revealed many biases and the results are conflicting. In a prospective study we examined the relationship between life events and affective phases in a group of bipolar patients with a long duration of the disease.

Ward atmosphere in acute psychiatric inpatient care: differences and similarities between patient and staff perceptions.

The purpose of the study was to compare patient and staff perceptions of the social climate in a psychiatric department, in order to investigate to what extent the two groups agree in their view of the ward milieu. Ninety-six patients and 66 staff members answered the Ward Atmosphere Scale (WAS) questionnaire, comprising a 100-item "real-form" concerning the ward atmosphere as it is actually perceived and a 100-item "ideal-form" concerning the atmosphere in an imagined "best of all" ward. Staff scores were significantly higher than patient scores on the WAS-R subscales Involvement, Spontaneity, Practical orientation, Personal problems orientation and Program clarity, and on the WAS-I subscales Spontaneity, Practical orientation, and Anger and aggression.

The stability of the Seasonal Pattern Assessment Questionnaire score index over time and the validity compared to classification according to DSM-III-R.

Background: In 1984, Rosenthal et al. described a group of patients characterised by repeated winter depression with atypical symptoms eventually followed by summer mania or hypomania (seasonal affective disorder, SAD). The relationship between SAD and the classical manic-depressive disorder is uncertain.
