Validity and reliability testing of the Quality of Life Scale, Swedish version in women with fibromyalgia -- statistical analyses

One consequence of constant widespread pain is a low quality of life. The purpose of the study was to examine whether the Quality of Life Scale, Swedish version (QOLS-S), regarded as a generic quality-of-life instrument, is a reliable and valid instrument for use in women with fibromyalgia (FM). Women with FM (n = 113) contributed data on the QOLS-S and other standardized instrument at three points in time. Internal consistency reliability estimates ranged from 0.89 to 0.92. Convergent construct validity was indicated by moderate agreement with a global life satisfaction question. Discriminant construct validity was denoted by low correlations with the physical functioning subscale of the SF-36. In a factor analysis three factors emerged: 'personal and social well-being', 'relations with others' and 'active participation'. A few of the items have high cross-loadings, and the instrument could be improved by rewording those items to more closely reflect one specific factor. Overall, these results provide evidence that the QOLS-S has acceptable validity and reliability for use in women with FM.

The Norwegian version of the Quality of Life Scale (QOLS-N). A validation and reliability study in patients suffering from psoriasis

The aim of this study was to adapt, validate, and test for reliability the Quality of Life Scale in Norwegian (QOLS-N) for patients suffering from psoriasis. Two hundred and eighty-two patients with psoriasis were included in the study. Self-reported health was measured using the SF-36. Disease severity was also measured in 95 patients using the Psoriasis Area and Severity Index (PASI). The reliability of the QOLS-N was computed using the internal consistency reliability (Cronbach's alpha) and the test-retest reliability test. Face and content validity and construct discriminant ability of the QOLS-N were assessed. The results indicated that the QOLS-N has highly satisfactory rates of test-retest reliability (r = 0.83) and internal consistency reliability (alpha 0.86). As expected, the QOLS-N had a lower correlation with physical health (r = 0.24, p < 0.000) and self-reported symptoms (r = -0.20, p < 0.001), and a higher correlation with mental health (r = 0.52, p < 0.000). The correlation with disease severity was not significant (-0.06). The results reported in the present paper are in accordance with those derived in other validation studies. The QOLS-N seems to be a reliable and valid measure of global quality of life in patients suffering from psoriasis.     

Empowerment in people with a mental illness: reliability and validity of the Swedish version of an empowerment scale

Empowerment has become a widespread concept in various social policy contexts referring to different marginalized groups. Empowerment has also been focused within the mental health field although little empirical research exists. The aim of the present study was to investigate internal consistency and construct validity of the Swedish version of an empowerment scale developed for people with a mental illness, Making Decisions. Ninety-two persons were subject to an interview also comprising assessments of quality of life, needs for care, psychiatric symptoms, psychosocial functioning, aspects of the social network, rejection experiences and attitudes of devaluation/discrimination towards people with mental illness. The results showed that the overall scale and the subscales had a good internal consistency, except for the subscale power–powerlessness. A factor analysis revealed two superordinate factors, self-esteem and activism and community and power, with a satisfactory internal consistency. These two factors showed a good construct validity with expected associations to validation measures. Stigma was most markedly associated with self-esteem and activism, and a higher level of education was most strongly associated with community and power. In conclusion, the Swedish version Making Decisions may well be used in further studies of empowerment among people with a mental illness.

Psychometric properties of the Swedish version of the Resilience Scale

The aim of this study was to investigate resilience in relation to age and gender, and to elucidate the underlying structure of the Swedish version of the Resilience Scale (RS). The RS, originally created by Wagnild and Young is a 25 items scale of Lickert type with possible scores ranges from 25 to 175, the higher the score, the stronger resilience. A standardized procedure was used for translation. The analysis was based on 1719 participants, 1248 women and 471 men, from eight different samples, aged from 19 to 103 years. We found that the participants estimated their resilience as relatively high. There was a significant relationship between age and resilience, for every year RS score increased with 0.134 units. There was no relation between gender and resilience. From a factor analyses five factors emerged, equanimity, meaningfulness, perseverance, existential aloneness and self-reliance reflecting the five dimensions described by Wagnild and Young. We concluded that the resilience is related to age, the older, the stronger resilience. Five underlying dimensions was identified, which can be seen as reflection of the theoretical assumptions behind the RS scale. The RS scale seems applicable to a Swedish population.     

Validity and reliability of the migraine-specific quality of life questionnaire (MSQ Version 2.1)

OBJECTIVE: To assess the scaling properties, reliability, and validity of the revised Migraine-Specific Quality of Life Questionnaire (MSQ) (Version 2.1) BACKGROUND: The MSQ is a disease-specific, quality-of-life instrument with three hypothesized scales that has been developed, tested, and revised. METHODS: The study used a multicenter, nondrug, prospective, parallel group, quasi-experimental design. Patients with migraine were recruited at outpatient headache specialty practices and were administered the MSQ, the Medical Outcomes Study 36-Item Short Form Health Survey (SF-36), and migraine symptom questionnaires at baseline, 4 weeks, and 12 weeks. Internal consistency (Cronbach alpha) and 4-week test-retest reproducibility (intraclass correlation coefficients) were estimated to assess reliability. Construct validity was assessed using an adaptation of the Campbell and Fiske multitrait-multimethod approach and by correlating MSQ scores with symptom measures. RESULTS: A total of 267 subjects enrolled in the trial. The criteria for summated rating scales were all met. The internal consistency coefficients ranged from 0.86 to 0.96, and the intraclass correlation coefficients ranged from 0.57 to 0.63 across the three dimensions. As anticipated, the MSQ dimensions had low-to-modest correlations with the two component scores of the SF-36 and were modestly to moderately correlated with migraine symptoms. CONCLUSIONS: The MSQ is a reliable instrument in the assessment of quality of life for patients with migraine with items that can be summed without weights. The MSQ has demonstrated evidence of construct validity.     

Adaptation and psychometric evaluation of the Swedish version of the Good Nursing Care Scale for Patients

The aim of this study was to adapt the instrument 'Good Nursing Care Scale for Patients' to Swedish conditions as a measure of patients' satisfaction, as well as estimating its reliability and validity. Following a pilot test, discussions in the author group, testing for readability among patients and judgement of content validity by a panel of experts, the final version was reduced to 72 items focusing on good caring. The refined instrument was assessed for internal consistency in 447 surgical in-patients, for 2 week test-retest reliability in 100 patients and subjected to orthogonal principal components factor analysis with varimax rotation, followed by second-order factor analysis. The internal consistency item-item correlation coefficient ranged from 0.15 to 0.91, correlation between each item and the total scale was >or=0.30 for 70 items, Cronbach's alpha coefficient for the final scale was 0.79 and test-retest reliability was 0.75. An orthogonal principal components factor analysis with varimax rotation was conducted on the final 71 items and the 15 first-order factors with eigenvalues >or=1 explained 66% of the total variance. A second-order factor analysis of these 15 factors as items resulted in a seven-factor solution. The total variance explained by the seven factors was 79%. Cronbach's alpha coefficient for the seven factors ranged between 0.32 and 0.95. The instrument seems reliable and valid to assess the patients' satisfaction with what happened during their hospital stay. To confirm the factor structure and improve factor consistency additional development and testing is suggested.
