Physical and emotional aspects of self-reported health status: a two-factor model of the short-form Breathing Problems Questionnaire.

The short version of the Breathing Problems Questionnaire (BPQ) is used as an outcome tool in pulmonary assessment. The aim of the study was to establish the validity of scoring BPQ with two subscales, reflecting emotional and physical components of health-related quality of life (HRQoL). Two subscales were suggested by exploratory factor analysis conducted on a data set of 97 patients with chronic obstructive pulmonary disease (COPD). Both subscales were significantly associated with the 6 minute walk test, total quality of life, and emotional stability. Only the physical subscale was significantly associated with FEV1, and only the emotional subscale was significantly associated with happiness. Overall, the sizes of the different correlations are consistent with the conceptual differentiation of the two subscales. We suggest that evaluation of rehabilitation can be made with the two subscales as well as an overall score of the BPQ.

Personality structure in patients with winter depression, assessed in a depression-free state according to the five-factor model of personality.

BACKGROUND: Depressive disorders are often associated with abnormalities of personality. This has also been found in Seasonal Affective Disorder, Winter Depression type (W-SAD), although relatively few and small studies have been done on this disorder so far, and mainly in the depressed phase. The aim of this study was to explore the personality structure and its possible background and clinical correlates in a larger group of patients with W-SAD, assessed in a non-depressed state, in the Five-Factor (or "Big Five") model of personality paradigm. METHODS: 82 persons (87% of those asked) with diagnosed W-SAD, most of them originally self-referred, who had previously received light treatment at our unit, completed a Norwegian version of an inventory yielding the personality factors Agreeableness, Surgency, Conscientiousness, Emotional stability, and Openness to experience. RESULTS: Compared to a Norwegian reference group, the mean scores of the W-SAD patients were significantly lower on the factors agreeableness, surgency and emotional stability, and significantly higher on conscientiousness. However, very few patients had scores outside the reference range. The personality factors do not seem to be associated with the core physiological manifestations of winter depression, but rather with the psychic aspects, and are poor predictors of response to light treatment. LIMITATIONS: Some reservations should be made as to the generalisability of the findings to SAD patients in general. Thus, increased conscientiousness may reflect help-seeking behaviour. CONCLUSIONS: Personality structure does not seem to predict occurrence of physiological reactions to lack of adequate daylight in autumn/winter, and is a poor predictor of improvement after light treatment, but may predict the associated psychic symptomatology.
