- BACKGROUND: Self-assessment questionnaires which measure the functional and affective consequences of chronic obstructive pulmonary disease (COPD) give valuable information about the effects of the disease and may serve as important tools with which to evaluate treatment. METHODS: A cross sectional comparative study was performed between patients with COPD (n = 68), stratified according to pulmonary function, and a healthy control group (n = 89). A battery of well established clinical and quality of life measures (the Sickness Impact Profile (SIP), Mood Adjective Check List (MACL), and Hospital Anxiety and Depression scale (HAD)) was used to examine in which functional and affective aspects the patient group differed from the control group and how these measures related to pulmonary function and smoking habits. RESULTS: Compared with the controls, COPD affected functional status in most areas, not just those requiring physical activity. Forty six patients with forced expiratory volume in one second (FEV1) below 50% predicted showed particularly high levels of dysfunction in ambulation, eating, home management, and recreation/ pastimes (SIP). Despite this, their level of psychosocial functioning and mood status was little different from that of the healthy controls. Among the patients, a subgroup reported substantial psychological distress, but mood status was only weakly, or not at all, related to pulmonary function. Smoking habits did not affect functional status or well being. CONCLUSIONS: Quality of life is not significantly affected in patients with mild to moderate loss of pulmonary function, possibly due to coping and/or pulmonary reserve capacity. This suggests that generic self-assessment questionnaires are of limited value for detecting the early consequences of COPD. However, in later stages of the disease they are sensitive enough to discriminate between patients with different levels of pulmonary dysfunction. The low correlations between the indices of pulmonary function and the indices of affective status suggest that well being depends, to a large extent, on factors outside the clinical domain.

Tidskriftsartikel (refereegranskat)abstract
- Fifty patients with severe chronic obstructive pulmonary disease (FEV1 < 50% pred.) were randomized to a rehabilitation group and a control group. The rehabilitation group took part in an individualized multidisciplinary, outpatient 12-month rehabilitation programme. Exercise training was intensive during the first 6 weeks and was then gradually replaced by an individual home-training programme and booster sessions. Controls received the usual outpatient care. Positive effects were found in terms of maximum symptom-limited exercise tolerance and walking distance (13.5 and 12.1% increase, respectively) in the rehabilitation group compared with the controls. Quality of life measurements showed minor beneficial effects on the Sickness Impact Profile, indicating a higher level of activity. No effect was seen on the St George's Respiratory Questionnaire or the Mood Adjective Check List. Patients expressed their enthusiasm for the rehabilitation programme in a study-specific questionnaire.

- The St George's Respiratory Questionnaire (SGRQ) was designed to measure quality of life (QoL) in obstructive pulmonary disease. Its reliability, validity and sensitivity have been demonstrated. The aim was to develop a Swedish version of the SGRQ and to confirm its scaling and clinical properties. The SGRQ was adapted for Swedish conditions following a translation-backtranslation procedure. The psychometric and clinical evaluation included 68 patients with chronic obstructive pulmonary disease (COPD). Supplementary QoL, clinical and physiological data were collected. A follow-up study was performed 1 yr later. Correlation analysis used a multitrait-multimethod model. Internal consistency reliability and discriminant validity were documented by performing a multitrait analysis. The results confirmed expected levels of associations. Correlation coefficients between the SGRQ total score and the Sickness Impact Profile Total score (a generic health measure), forced expiratory volume in one second (FEV1) and 6 min walking distance were 0.69, -0.42 and -0.61 respectively. The pattern of correlations in the Swedish data set was very similar to that of the original. The stability of the SGRQ scores was confirmed at follow-up after 1 yr. The reliability was satisfactory, with Cronbach's alpha coefficients >0.80 for the SGRQ and its subdimensions. In conclusion, the Swedish version of the St George's Respiratory Questionnaire is reliable, valid and compares well with the corresponding tests of the original version.

- Background. The quality of life (QL)of cancer patients has attracted an increasing interest in recent years. Patients with head and neck cancer often have troublesome symptoms due to the disease and to treatment side effects, which will have an impact on the patient's QL. The aim of this study was to evaluate the possibility of studying QL in relation to well-known clinical parameters. Methods. Patient's QL was evaluated according to the European Organization for Research and Treatment of Cancer Quality of Life Core Questionnaire (EORTC QLQ-C30) combined with a diagnosis-specific questionnaire. Quality of life was measured in a cross section of head and neck cancer patients (n = 48) and related to nutritional status, energy intake, severity of disease, and 2-year survival. Results. Fifty-one percent of the patients (mean age, 67 years) fulfilled the criteria proposed for malnutrition, and 55% had a negative energy balance. We did not find any correlation between the severity of the cancer disease and the patient's self-rated QL. However, we found significantly better QL ratings among the 2-year survivors (mean, 63; range 52-76 versus mean, 42; range, 31-54; p < .05). There were few correlations between the QL items and malnutrition. Conclusions. Quality of life measurements offer objective information on well-being, sometimes quite opposite that of other clinical parameters, such as tumor stage. Furthermore, QL measurements may be of prognostic value concerning the survival of head and neck cancer patients. (C) 1998 John Wiley & Sons, Inc.

- METHODS: Two studies of psychosocial interventions in head and neck cancer patients at different stages of their disease were performed. We explored the feasibility and effectiveness of different approaches, offered for the first time to this population. The first study concerned long-term group psychological therapy for patients with newly diagnosed head and neck cancer. Quality of life was measured longitudinally for 1 year and compared with that of a control group. The second study comprised a short-term psychoeducational program 1 year after treatment for head and neck cancer. Quality-of-life assessments were made repeatedly from diagnosis until 1 month after the intervention. RESULTS: Thirteen patients started the psychological group therapy, and 8 of them completed both the intervention and evaluation procedure. The quality of life of the therapy group improved more than that of a control group in most areas measured during the study year, in particular psychiatric morbidity, social functioning, emotional functioning, and global quality of life. The results indicate benefits from the therapy, although the therapy group scored worse than the control group at diagnosis. Most of the variables representing functioning and symptoms improved after the 1-week psychoeducational program, especially items reflecting "trouble eating" and "problems enjoying your meals." Patients' judgments of the intervention quality indicated satisfaction with all separate elements, mostly education, about cancer and the opportunity to socialize with the other guests. CONCLUSION: These pilot studies suggest that head and neck cancer patients can benefit from different psychosocial interventions. Quality-of-life questionnaires were well accepted and sensitive to changes during the studies. Thus our early findings seem promising and would justify confirmation in larger studies.

Tidskriftsartikel (refereegranskat)abstract
- Department of Internal Medicine, Göteborg University, Sweden. The aims of this study were to: describe dietary intakes of obese and nonobese middle-aged women using a validated food frequency questionnaire; to assess dietary restraint, disinhibition, and hunger by the three factor eating questionnaire (TFEQ) in obese and nonobese samples and determine which of the factors are independently associated with obesity; and to examine correlations between selected nutritional variables and the TFEQ factors. Subjects studied included 179 obese Swedish women (BMI > 32) and 147 nonobese population-based controls (BMI < 28). Age-adjusted mean energy intake was significantly higher in obese women (2730 +/- 78 vs. 2025 +/- 85 kcal, p < 0.0001). In absolute and relative terms, fat intake was higher and alcohol intake was lower in the obese subjects. Disinhibition was the strongest TFEQ factor independently differentiating the obese and nonobese states, i.e., after adjustment for restraint and hunger. Within the obese sample, strong associations were seen between energy intake and disinhibition (p = 0.0005) and hunger (p = 0.0004). The association between energy intake and restrained eating was negative and weaker (p = 0.04). No such associations were seen in nonobese women. Thus, using a dietary instrument that is valid and unbiased with respect to obesity, strong psychological correlates, possibly causal, of variability in energy intake were detected in middle-aged women with obesity. Disinhibition is associated with both obesity and high-energy intakes and is therefore an important factor to consider in the treatment of women with obesity.

Tidskriftsartikel (refereegranskat)abstract
- The validity of the Swedish SF-36 Health Survey was examined, replicating techniques used in the U.S. validation. Principal components analysis was used to test the internal structure of the eight SF-36 scales in relation to hypothesized associations with the two major dimensions of health--physical and mental. Hypothesized relationships between scales and external criteria were also examined by means of clinical group contrasts. Both the principal components analysis and clinical group contrasts largely replicated U.S. findings, which supported the cross-cultural stability of the SF-36 in Sweden. As expected, the Physical Functioning and Mental Health scales were most sensitive to clinical manifestations of medical and mental health, respectively. The General Health scale was associated more with physical than mental health. However, the Social Functioning scale and particularly the Vitality scale were more related to mental health in Sweden than in the corresponding U.S. study. Cultural differences and variation in study samples and selection criteria were suggested as possible explanatory factors for these differences.
