Neuro-QOL: brief measures of health-related quality of life for clinical research in neurology.

OBJECTIVE: To address the need for brief, reliable, valid, and standardized quality of life (QOL) assessment applicable across neurologic conditions. METHODS: Drawing from larger calibrated item banks, we developed short measures (8-9 items each) of 13 different QOL domains across physical, mental, and social health and evaluated their validity and reliability. Three samples were utilized during short form development: general population (Internet-based, n = 2,113); clinical panel (Internet-based, n = 553); and clinical outpatient (clinic-based, n = 581). All short forms are expressed as T scores with a mean of 50 and SD of 10. RESULTS: Internal consistency (Cronbach α) of the 13 short forms ranged from 0.85 to 0.97. Correlations between short form and full-length item bank scores ranged from 0.88 to 0.99 (0.82-0.96 after removing common items from banks). Online respondents were asked whether they had any of 19 different chronic health conditions, and whether or not those reported conditions interfered with ability to function normally. All short forms, across physical, mental, and social health, were able to separate people who reported no health condition from those who reported 1-2 or 3 or more. In addition, scores on all 13 domains were worse for people who acknowledged being limited by the health conditions they reported, compared to those who reported conditions but were not limited by them. CONCLUSION: These 13 brief measures of self-reported QOL are reliable and show preliminary evidence of concurrent validity inasmuch as they differentiate people based upon number of reported health conditions and whether those reported conditions impede normal function.

Stress and symptoms in patients with interstitial cystitis: a life stress model.

Objectives. Stress-related exacerbation of interstitial cystitis (IC) symptoms has frequently been reported. Previous research has found stress-related IC symptom exacerbation in an experimental model. However, this relationship has not been objectively examined with daily life stressors. We used a prospective daily symptom diary method to investigate the relationships among stress and bladder symptoms in patients with IC and age-matched healthy controls.Methods. Forty-five previously diagnosed female patients with IC completed a bladder symptom and stress diary nightly for 1 month; 31 female age-matched healthy controls completed a similar diary for 7 days. The symptom questions were modified from the Interstitial Cystitis Data Base study.Results. Patients reported greater mean daily stress, bladder pain, urgency, and daytime and nocturnal frequency than controls (all P values less than 0.001). Among all patients, a significant relationship between stress and urgency was observed. In addition, a significant relationship between stress and pain was observed among patients with moderate and severe disease. As the disease severity increased, more pronounced relationships between stress and the symptoms of urgency and pain were evidenced. Greater stress was associated with greater nocturnal frequency among patients with more severe disease. These stress-symptom relationships were not observed among the controls.Conclusions. Higher levels of stress were related to greater pain and urgency in patients with IC but not in the controls. In addition, the relationship of stress and these IC symptoms was stronger among patients with more severe disease. The results indicate that life stress is associated with greater IC symptoms, particularly among patients whose disease is not well controlled.

Quality of life and mood in women receiving extensive chemotherapy for gynecologic cancer.

BACKGROUND: Quality of life (QOL) and mood were investigated among women who had received intensive chemotherapy for at least 1 year for advanced gynecologic cancers. Relationships of coping styles to QOL and mood in these patients also were examined. METHODS: Twenty-four patients who had been receiving chemotherapy continuously or intermittently for at least 1 year were recruited into the study. To control for the diagnosis of cancer and for prior hysterectomy, 24 age-matched early stage gynecologic cancer patients not receiving chemotherapy and assessed 1 year following diagnosis were examined as a comparison group. All subjects completed psychosocial assessments at a clinic visit. Medical information was retrospectively abstracted from patient charts. RESULTS: Decrements in physical, emotional, and functional well-being were reported by extensively treated patients, whereas social well-being and satisfaction with the relationship between doctor and patient were close to the norms of the comparison group. Extensively treated patients reported more fatigue and less vigor, but their depression and anxiety did not differ from early stage patients. Almost all extensively treated patients reported that their treatment had been worthwhile. Patients using avoidant coping reported poorer physical and emotional well-being, along with greater anxiety, depression, fatigue, and total mood disturbance. Those using active coping reported better social well-being, better relationships with their doctors, and less overall distress. CONCLUSIONS: This study indicates that gynecologic oncology patients extensively treated with chemotherapy experienced substantial decrements to quality of life, and yet treatment still was considered worthwhile by a majority of patients. Avoidant coping may be a particular risk factor for poor QOL and greater distress.

Stress and symptomatology in patients with interstitial cystitis: a laboratory stress model.

PURPOSE: Although patients with interstitial cystitis frequently report symptom exacerbation due to stress, to our knowledge this association has not been empirically examined. We evaluated the effects of a laboratory mental stress challenge on symptoms of urgency and pain in patients with interstitial cystitis and healthy controls. MATERIALS AND METHODS: A total of 14 females with interstitial cystitis and 14 age matched controls participated in a laboratory session, including a 60-minute baseline measurement, 25 minutes of mental stress tasks and 75 minutes of recovery. Acute symptoms of pain and urgency were assessed at voiding 15 minutes before the stressor, and 25, 70 and 100 minutes after stressor onset. Chronic symptoms were evaluated by questions from the Interstitial Cystitis Data Base survey. RESULTS: Patients reported significantly greater pain and urgency than controls at all 4 voidings (p <0.005). Pain increased in patients from the prestressor point to 25 minutes after stressor onset (p <0.005), remained elevated at 70, and decreased between 70 and 100. At 100 minutes patient pain remained significantly elevated above baseline (p = 0.018). Patient urgency was significantly elevated over baseline by 70 minutes after stressor onset (p <0.001) and significantly decreased between 70 and 100 minutes (p <0.002). Controls had no symptom changes with stress. CONCLUSIONS: These findings indicate that an acute stressor evokes increased symptoms of pain and urgency in patients with interstitial cystitis but not in controls. Findings are consistent with sympathetic effects on inflammatory processes in interstitial cystitis. However, further evaluation of the mechanisms underlying stress related interstitial cystitis symptom exacerbation is needed to provide a more comprehensive understanding of these phenomena.

Effects of relaxation and stress on the capsaicin-induced local inflammatory response.

OBJECTIVE: Although stress is known to modulate the inflammatory response, there has been little experimental examination of the effects of stress and stress reduction on inflammation in humans. In particular, the effects of stress and relaxation on neurogenic inflammation have been minimally studied. This study examines the effects of three experimental manipulations: mental stress, relaxation, and control on the local inflammatory response evoked by the intradermal injection of capsaicin, the active ingredient in chili peppers. METHODS: Fifty subjects (28 men and 22 women) were pretrained in relaxation using an imagery-based relaxation tape and then randomized to experimental condition. Subjects participated in an evening reactivity session including 20 minutes of a stress (Stroop test), relaxation (tape), or control (video) manipulation, followed by a capsaicin injection in the forearm. Digitized flare measurements were taken for 1 hour postcapsaicin, and measurements of cardiovascular variables, cortisol, adrenocorticotrophic hormone, and norepinephrine were taken at regular intervals. RESULTS: The size of the maximum capsaicin-induced flare was significantly smaller in the relaxation condition than in the stress or control conditions, which did not differ from each other. Increases in norepinephrine, heart rate, and systolic blood pressure during the experimental task, but not after capsaicin, significantly predicted size of maximum flare and total area under the curve of flare measurements. CONCLUSIONS: These findings suggest that stress reduction may affect local inflammatory processes. Results are consistent with sympathetic modulation of the effects of relaxation on the flare response.

Recreational drug use concurrent with abuse or dependence on other psychoactive substances.

In an effort to identify instances of the non-problematic use of a drug concurrent with the problematic use of one or more other drugs, we used structured interviews to obtain comprehensive drug use histories from 48 clients admitted to an intensive outpatient program. We classified clients on the basis of whether they demonstrated evidence of concurrent problematic and non-problematic drug use (Index and Probable Index cases) or only problematic drug use patterns (Non-Index cases). Both Index and Non-Index drug use patterns were about equally common in our sample. Both Index and Probable Index cases used a variety of drugs in a non-problematic manner and were generally congruent in their self-labelling of their drug use relative to their DSM-IV status for each drug used. We discuss several limitations of the study, including our reliance on retrospective, self-report data; potential problems with generalization to other populations; and possible changes in drug use patterns over time.

Acceptance of moderate drinking by alcoholism treatment services in Canada.

OBJECTIVE: The present study was conducted to provide a nationwide survey of acceptance of nonabstinence goals and related alcoholism treatment practices by Canadian alcoholism treatment services. METHOD: A random sample of 335 Canadian alcoholism treatment service agencies were mailed a 4-page questionnaire designed to assess acceptance of moderate drinking as a drinking goal and related alcoholism treatment practices. RESULTS: Acceptance varied by type of service, with considerably more acceptance by outpatient programs (62%) and mixed inpatient/outpatient programs (43%) than inpatient/detoxification/ correctional facilities (27%) and halfway houses (16%). Two-thirds of the respondents who reported moderate drinking as unacceptable in their own agencies categorically rejected moderation for all alcoholism clients. CONCLUSIONS: Individuals seeking services in Canadian alcoholism treatment agencies are more likely to have a choice of drinking goals if they present to an outpatient program than a residential institution, and Canadian agencies appear more accepting of moderation goals than American programs, but less accepting than British and Norwegian service agencies.
