PURPOSE Despite considerable interest in examining spirituality in health-related quality-of-life studies, there is a paucity of instruments that measure this construct. The objective of this study was to test a valid and reliable measure of spirituality that would be useful in patient populations. METHODSWe conducted a multisite, cross-sectional survey using systematic sampling of adult outpatients at primary care clinic sites in the Kansas City metropolitan area (N = 523). We determined the instrument reliability (Cronbach's α, test-retest) and validity (confi rmatory factor analysis, convergent and discriminant validation) of the Spirituality Index of Well-Being (SIWB). RESULTSThe SIWB contains 12 items: 6 from a self-effi cacy domain and 6 from a life scheme domain. Confi rmatory factor analysis found the following fi t indices: χ 2 (54, n = 508) = 508.35, P <.001; Comparative Fit Index = .98; TuckerLewis Index = .97; root mean square error of approximation = .13. The index had the following reliability results: for the self-effi cacy subscale, α = .86 and test-retest r = 0.77; for the life scheme subscale, α = .89 and test-retest r = 0.86; and for the total scale α = .91 and test-retest r = 0.79, showing very good reliability. The SIWB had signifi cant and expected correlations with other quality-of-life instruments that measure well-being or spirituality: Zung Depression Scale (r = 0 -.42, P <.001), General Well-Being Scale (r = 0.64, P <.001), and Spiritual Well-Being Scale (SWB) (r = 0.62, P <.001). There was a modest correlation between the religious well-being subscale of the SWB and the SIWB (r = 0.35, P <.001). CONCLUSIONSThe Spirituality Index of Well-Being is a valid and reliable instrument that can be used in health-related quality-of-life studies. INTRODUCTIONT here is continued interest in examining the association of religion and spirituality with health-related outcomes.1 Despite this interest, the use of small, nongeneralizable samples, confounding, and the lack of valid and reliable instruments that measure spirituality or religiosity compromise most studies in this fi eld.2 Although there is no shortage of instruments from the disciplines of sociology, psychology, and pastoral theology and chaplaincy, 3 these measures frequently are not applicable or useful in studies of individual or population health.The current study describes the development and evaluation of the Spirituality Index of Well-Being (SIWB), which was designed to measure the effect of spirituality on subjective well-being. Two assumptions guided our study design and analysis. First, we recognized that no global, yet parsimonious, instrument captures the complexity and depth of spirituality in any context, health care or otherwise. Next, based on our qualitative From a cultural and social perspective, spirituality and religion are especially salient in the lives of the elderly minority populations, 5,6 particularly within the settings of serious illness and end-of-life care.7 From a population health perspective, inc...

“…The appropriateness, clarity and coverage of the items may be aspects of the validity. 4,8,9 The construct validity refl ects the capacity of the instrument to measure a set of behavioral patterns that are related to each other and are known to be associated with the phenomenon that is being measured. The criterion validity is the most popular means of determining validity and described an empirical relationship between a measurement and a reliable criterion of some type.…”

OBJECTIVE:To evaluate the reliability of an instrument for classifying elderly people regarding their capacity for self-care, which was developed to assist occupational therapists in attending elderly people at primary healthcare units. METHODS:Stability and internal consistency tests were carried out. To validate the instrument, tests were applied to a sample of 30 individuals aged 60 years and over, on two occasions. The statistical analysis was performed after careful grouping of the responses. This led to the formulation of a simplifi ed version of the instrument. The stability of this version was assessed using the kappa coeffi cient and the internal consistency by Cronbach's alpha coeffi cient. RESULTS:The stability ranged from moderate to excellent. The internal consistency was checked only for areas that were shown to be appropriate for using the methodology, based on calculations of Cronbach's alpha: three of the six questions in the "social profi le" area and the blocks of basic and instrumental activities of daily living in the "functional capacity" area, which respectively consisted of nine and eight activities. CONCLUSIONS:Following the stability and internal consistency tests, the instrument made it possible to succinctly and simply classify elderly people with regard to their functional capacity for basic and instrumental activities, and to characterize them regarding other aspects of self-care. The evidence regarding its reliability and validity could be expanded by means of new studies.

“…3 ± 5 QL, being thus at least partly measurable, is probably more important in relation to how patients adapt to their condition than many of the traditional means of gauging the results of clinical research. 6,7 In the present study, we have applied modern QL questionnaire technique in a population of permanently-disabled spinal patients with traumatic cord paralysis.…”

A brief quality-of-life (QL) questionnaire was derived empirically from a cross-sectional study of 98 SCI-patients (83% men, median age 33.5 years, and median time after injury 2.3 years). A comprehensive general battery of well-established questionnaires (Sickness Impact Pro®le (SIP), Mood Adjective Check List (MACL), and Hospital Anxiety and Depression (HAD) scale) was combined with a study-speci®c set of questions to constitute patients' QL. A stepwise analysis model was used to de®ne key areas and questions to be included in a brief SCI-adapted questionnaire. The central areas that independently mattered for SCI-patients' perception of good QL included mental health (no depressive feelings), physical and psychosocial dysfunction (no, or few and minor, limitations in mobility, body care and movement and social interaction), and SCI-related problems (no or little perceived di culty with loss of independence due to injury). A 22-item questionnaire is suggested for routine clinical follow-up to assess more accurately when optimal treatment and services have been delivered.
