BACKGROUND Although studies show that cancer patients consider fatigue as an important problem, few, if any, studies have quantified the impact of fatigue on overall quality of life (QoL) in cancer patients. In the present study, we evaluated the relative impact of different QoL domains/subscales, including fatigue, on overall QoL in cancer patients preceding radiotherapy. PATIENTS AND METHOD...

PURPOSE To explore the psychometric properties of the 13 subscales of the NEI-RQL-42 questionnaire using Rasch analysis. METHODS The NEI-RQL-42 is a refractive error-related quality of life (QoL) questionnaire with a complex design; its 13 subscales contain 42 questions, which include 16 different question/response category formats. It was completed by 100 laser refractive surgery subjects (s...

OBJECTIVE This study was conducted to determine the psychometric properties of the Swedish version of the Diabetes Empowerment Scale (Swe-DES-23). RESEARCH DESIGN AND METHODS A convenience sample of 195 patients with type 1 and type 2 diabetes completed the Swe-DES-23 questionnaire.

Aim. The clinimetric aspects of Eysenck's two big personality factors (neuroticism and extraversion) were originally identified by principal component analysis but have been insufficiently analysed with item response theory models. Their relationship to states of melancholia and anxiety was subsequently analysed. Method. Patients with chronic idiopathic pain disorder were included in the study....

CONTEXT Patients in long-term remission of Cushing's syndrome (CS) commonly report impaired quality of life (QoL). The CushingQoL questionnaire is a disease-specific QoL questionnaire for patients diagnosed with CS. The developers of the CushingQoL recommend using a global (total) score to assess QoL. However, the global score does not capture all aspects of QoL as outlined by the World Health ...

BACKGROUND Quality of life (Qol) is an increasingly used outcome measure in dementia research. The QUALIDEM is a dementia-specific and proxy-rated Qol instrument. We aimed to determine the inter-rater and intra-rater reliability in residents with dementia in German nursing homes. METHODS The QUALIDEM consists of nine subscales that were applied to a sample of 108 people with mild to severe de...

BACKGROUND Venom allergy is a rare but life-threatening disease and may have a considerable impact on the health-related quality of life (HRQoL) of patients, especially children. This paper presents development of the HRQoL scale for children and adolescents with Hymenoptera venom allergy (HVA).

Cognitive-perceptual, interpersonal, and disorganized subscales of the Schizotypal Personality Questionnaire-Brief (SPQ-B), reflecting the three commonly used subscales of the full-version SPQ, have been used in a number of studies. However, the factorial validity of SPQ-B subscales remains to be clarified. Utilizing data from 825 undergraduate students, confirmatory factor analyses involving t...
