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.     

Psychometric properties of the Chinese‐version Quality of Nursing Work Life Scale

In this study, we developed and tested the psychometric properties of the Chinese‐version Quality of Nursing Work Life Scale along seven subscales: supportive milieu with security and professional recognition, work arrangement and workload, work/home life balance, head nurse's/supervisor's management style, teamwork and communication, nursing staffing and patient care, and milieu of respect and autonomy. An instrument‐development procedure with three phases was conducted in seven hospitals in 2010–2011. Phase I comprised translation and the cultural‐adaptation process, phase II comprised a pilot study, and phase III comprised a field‐testing process. Purposive sampling was used in the pilot study (n = 150) and the large field study (n = 1254). Five new items were added, and 85.7% of the original items were retained in the 41 item Chinese version. Principal component analysis revealed that a model accounted for 56.6% of the variance with acceptable internal consistency, concurrent validity, and discriminant validity. This study gave evidence of reliability and validity of the 41 item Chinese‐version Quality of Nursing Work Life Scale.     

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.

Validity and reliability of the Norwegian version of the Ferrans and Powers Quality of Life Index

The purpose of this study was to examine the validity and reliability of the Norwegian version of the Ferrans and Powers Quality of Life Index in a sample of 131 men and women with newly diagnosed cancer. The Quality of Life Index was translated into Norwegian using a standardized international approach, including back-translation. The findings showed high internal consistency reliability for the global score (alpha = 0.93 (test)) as well as for the following domains: health and functioning (alpha = 0.88), socio-economic (alpha = 0.82), psychological/spiritual (alpha = 0.82) and family (alpha = 0.79). The test-retest reliability after 3-4 weeks was 0.78 for the global score. A factor analysis partially confirmed the different subscales. In conclusion, the Quality of Life Index was found to be reliable and had sufficient validity to be used for measuring quality of life in Norwegian cancer patients.

The adaptation of a Danish version of the Pain Self‐Efficacy Questionnaire: reliability and construct validity in a population of patients with fibromyalgia in Denmark

The aim of this study was to translate, culturally adapt and evaluate the psychometric properties of the Pain Self‐Efficacy Questionnaire (PSEQ) in a population of patients with fibromyalgia in Denmark. The study sample included 102 patients diagnosed with fibromyalgia referred to a specialist clinic. The PSEQ was translated and adapted to a Danish setting using a standard stepw‐ise forward–backward translation procedure, followed by initial testing and focus group interview. Reliability was examined by analysing internal consistency and test–retest agreement. Construct validity was exami‐ned by investigating dimensionality, targeting, local independence, category functioning and differential item functioning (DIF). Reliability was high: Cronbach's alpha 0.88, test–retest correlation 0.93, intraclass correlation coefficient (ICC) 0.89 and item–total correlations 0.44–0.70. Factor analyses and item response (IRT) models indicated unidimensionality, and the PSEQ‐DK was well targeted to the sample. High interitem correlation was observed between two items, indicating local dependence, and item misfit and DIF were observed for a few items. However, the overall fit of the scale to a single‐factor model and IRT models supported acceptable construct validity. The PSEQ‐DK showed acceptable psychometric properties and can therefore represent a reliable and valid measure for evaluating self‐efficacy in patients with fibromyalgia in Denmark.     

Evaluation of a Swedish Version of the Ostomy Adjustment Scale

The main aim of the present study was to adapt an instrument measuring patients' adjustment to life with an ostomy to Swedish conditions and to test reliability and validity of the adapted instrument. The Ostomy Adjustment Scale (OAS), which is focused on three domains: physical function, psychologic state, and social interaction, was selected as suitable. After translation into Swedish, equivalence and internal consistency of the scale were calculated. Subjects with various types of urine or faeces diversions were recruited for self-rating with the OAS and a visual analogue scale estimating total quality of life (QOL). The instruments were tested in 48 patients with five different diagnoses, 36 with and 12 without ostomy, and re-tests were carried out in 25 of the patients. Reliability (Cronbach's alpha) was 0.95. A positive correlation was found between the OAS and QOL (r = 0.67), indicating that the instrument has some validity.     

The reliability and validity of the Chinese version of the Trait Anxiety Scale for Children

The availability of a valid and reliable tool that accurately measures and differentiates pre-operative anxiety level of children is crucial before any intervention can be appropriately planned, provided, and evaluated. The purposes of this study were to translate the original Trait Anxiety Scale for Children into Chinese and evaluate the psychometric properties of the newly translated scale for its utility in clinical practice and research. Five hundred and nineteen children from a primary school were recruited for this study. The instrument demonstrated adequate internal consistency reliability, and strong evidence of content and construct validity. Factor analysis confirmed the construct validity of the scale with a good fit between the factor structure of the scale and the observed data. Results suggest that the Chinese version of the Trait Anxiety Scale for Children can be used as a self-report assessment tool in measuring trait anxiety level of Chinese children ages 7-12 years.

Psychometric properties of the Swedish version of the Purpose in Life scale

Scand J Caring Sci; 2010; 24; 41–48
Psychometric properties of the Swedish version of the Purpose in Life scale
The aim of this study was to test the theoretical assumptions beyond the Purpose in Life (PIL) scale, and to elucidate the underlying structure of the Swedish version of the PIL. The PIL, originally created by Crumbaugh and Maholick, is a 20-item scale of the Lickert type with possible scores ranges from 20 to 140, the higher score, the stronger PIL. The analysis was based on 449 participants, 62% of whom were women, from five different samples, ranging from 19 to 103 years old. An exploratory factor analysis restricted to three factors was performed. The factors were labelled meaning in existence, freedom to create meaning in daily life, and will to find meaning in future challenges. These factors reflected the three dimensions described by Frankl. Cronbach's alpha coefficient for the total scale was 0.83 and varied between 0.54 and 0.83 in the three factors. We concluded that the Swedish version of the PIL scale seems to have construct validity and reliability. Our results give support to the fact that the PIL scale captures and confirms the theoretical assumptions of Frankl's existential theory. We consider the PIL scale to be both feasible and appropriate for use in nursing research.
