Translation and psychometric evaluation of a French version of the Readiness for Hospital Discharge Scale.

AIMS AND OBJECTIVES: To evaluate the reliability and the factor structure of the Readiness for Hospital Discharge Scale - French version. BACKGROUND: The patient's perspective is essential when assessing risk for adverse events at hospital discharge. Developed in the USA, the Readiness for Hospital Discharge Scale is the only instrument that measures an individual's self-perception of readiness before leaving the hospital. A French version of the Readiness for Hospital Discharge Scale was developed and validated. DESIGN: Cross-sectional study. METHODS: A convenience sample of 265 older inpatients from four medical units was selected. The translation and cultural adaptation of the scale involved experts in gerontology and the French language and included back translation. The items were semantically evaluated and pretested in 10 older inpatients. The scale's psychometric properties were internally validated by using confirmatory and exploratory factor analyses. Reliability was assessed by examining the internal consistency of its items. RESULTS: Goodness-of-fit indices of the confirmatory factor analyses were not adequate, but reliability was acceptable (Cronbach's α = 0·80). Exploratory factor analysis of the French version provided results close to those described for the English version, with three similar subscales (physical and emotional readiness, coping with medical treatment and personal care), whereas the initially described Expected Support subscale was not identified in the French version. CONCLUSION: The Readiness for Hospital Discharge Scale - French version appears to be partially consistent with its original English version, but requires additional adaptation to fully take into account the Swiss context and culture to achieve its original aim. RELEVANCE TO CLINICAL PRACTICE: Assessing patient readiness for hospital discharge before leaving hospital could help nurses to improve the discharge planning process and achieve better patient preparedness and care coordination.

Ascertaining late-life depressive symptoms in Europe: an evaluation of the survey version of the EURO-D scale in 10 nations. The SHARE project.

The reported prevalence of late-life depressive symptoms varies widely between studies, a finding that might be attributed to cultural as well as methodological factors. The EURO-D scale was developed to allow valid comparison of prevalence and risk associations between European countries. This study used Confirmatory Factor Analysis (CFA) and Rasch models to assess whether the goal of measurement invariance had been achieved; using EURO-D scale data collected in 10 European countries as part of the Survey of Health, Ageing and Retirement in Europe (SHARE) (n = 22,777). The results suggested a two-factor solution (Affective Suffering and Motivation) after Principal Component Analysis (PCA) in 9 of the 10 countries. With CFA, in all countries, the two-factor solution had better overall goodness-of-fit than the one-factor solution. However, only the Affective Suffering subscale was equivalent across countries, while the Motivation subscale was not. The Rasch model indicated that the EURO-D was a hierarchical scale. While the calibration pattern was similar across countries, between countries agreement in item calibrations was stronger for the items loading on the affective suffering than the motivation factor. In conclusion, there is evidence to support the EURO-D as either a uni-dimensional or bi-dimensional scale measure of depressive symptoms in late-life across European countries. The Affective Suffering sub-component had more robust cross-cultural validity than the Motivation sub-component.

Psychometric evaluation of the French version of the questionnaire attitudes towards morphine use; a cross-sectional study in Valais, Switzerland.

BACKGROUND: In Switzerland, nurses are allowed to prescribe and administer morphine in emergency situations without a doctor. Still, nurses and other health professionals are often reluctant to prescribe and administer morphine for pain management in patients. No valid French-speaking instrument is available in Switzerland to assess the attitudes of nurses and other health professionals towards the prescription and administration of morphine. In this study, we evaluated the psychometric properties of the French version of the questionnaire "Attitudes towards morphine use". METHODS: The instrument was derived from an Italian version. Forward and back translations of the questionnaire were performed. Item analysis and construct validity were assessed between April and December 2010 in a cross sectional study including five Swiss hospitals in a sample of 588 health professionals (533 nurses, mean age 38.3 ± 10.2 years). Thirty subjects participated in test-retest reliability. RESULTS: The time to complete the instrument ranged between 12 and 15 minutes and neither floor nor ceiling effect were found. The initial 24-item instrument showed an intraclass correlation (ICC) of 0.69 (95% CI: 0.64 to 0.73, P < 0.001), and a Cronbach's α of 0.700. Factor analysis led to a six-component solution explaining 52.4% of the total variance. After excluding five items, the shortened version showed an ICC of 0.74 (95% CI, 0.70 to 0.77, P < 0.001) and a Cronbach's α of 0.741. Factor analysis led to a five-component solution explaining 54.3% of the total variance. The five components were named "risk of addiction/dependence"; "operational reasons for not using morphine"; "risk of escalation"; "other (non-dependence) risks" and "external (non-operational) reasons". In test-retest, the shortened instrument showed an ICC of 0.797 (95% CI, 0.630 to 0.911, P < 0.001) and a Cronbach's α of 0.797. CONCLUSIONS: The 19-item shortened instrument assessing attitudes towards the prescription and administration of morphine showed adequate content and construct validity.

Comparison of the NEO-FFI, the NEO-FFI-R and an alternative short version of the NEO-PI-R (NEO-60) in Swiss and Spanish samples

Three different short versions of the NEO-PI-R were compared: The NEO-FFI, the NEO-FFI-R, and a new short version developed in the current study (NEO-60). This new version is intended to improve the psychometric characteristics of the original NEO-FFI, specially in regard to the factor structure at the item-level. A French version of the NEO-PI-R was given to 1090 Swiss subjects, whereas the Spanish (Castilian) version of the NEO-PI-R was administered to 1006 Spanish subjects. Results replicate the limitations of the NEO-FFI already found in other countries. Compared to the NEO-FFI, reliability coefficients and factor structure was enhanced by the NEO-FFI-R and the NEO-60 in both samples, although substantial differences were not found. The factor structure of the NEO-60 shows the best fit since only three items do not load mainly on their own factor in both samples. Besides, correlations between items and NEO-PI-R domain scores are also higher for the items included in the NEO-60 version. On the other hand, convergent correlations with the NEO-PI-R dimensions were satisfactory irrespective of the version, and confirmatory factor analyses show slight differences among the different models generated after the three short versions.

Reliability and validity of the cross-culturally adapted French version of the Core Outcome Measures Index (COMI) in patients with low back pain.

PURPOSE: To conduct a cross-cultural adaptation of the Core Outcome Measures Index (COMI) into French according to established guidelines. METHODS: Seventy outpatients with chronic low back pain were recruited from six spine centres in Switzerland and France. They completed the newly translated COMI, and the Roland Morris disability (RMQ), Dallas Pain (DPQ), adjectival pain rating scale, WHO Quality of Life, and EuroQoL-5D questionnaires. After ~14 days RMQ and COMI were completed again to assess reproducibility; a transition question (7-point Likert scale; "very much worse" through "no change" to "very much better") indicated any change in status since the first questionnaire. RESULTS: COMI whole scores displayed no floor effects and just 1.5% ceiling effects. The scores for the individual COMI items correlated with their corresponding full-length reference questionnaire with varying strengths of correlation (0.33-0.84, P < 0.05). COMI whole scores showed a very good correlation with the "multidimensional" DPQ global score (Rho = 0.71). 55 patients (79%) returned a second questionnaire with no/minimal change in their back status. The reproducibility of individual COMI 5-point items was good, with test-retest differences within one grade ranging from 89% for 'social/work disability' to 98% for 'symptom-specific well-being'. The intraclass correlation coefficient for the COMI whole score was 0.85 (95% CI 0.76-0.91). CONCLUSIONS: In conclusion, the French version of this short, multidimensional questionnaire showed good psychometric properties, comparable to those reported for German and Spanish versions. The French COMI represents a valuable tool for future multicentre clinical studies and surgical registries (e.g. SSE Spine Tango) in French-speaking countries.

Construct validity of the French version of the PRWE (Patient Rated Wrist Evaluation) with the French version of the DASH (Disabilities Arm Shoulder and Hand) is good to very good in a population of patients with wrist injuries in an inpatient rehabilitation unit

Objective.- The Patient-Rated Wrist Evaluation is a specific questionnaire for the wrist [1]. It consists of 15 questions with a total score of 100. It was recently translated into French [2]. However, its validity has not been tested in this language. The Disabilities Arm Shoulder and Hand (DASH), with well-established psychometric properties, is considered as the reference questionnaire for the evaluation of upper extremities. The objective of this study is to measure the construct validity of the PRWE-F with the DASH-F in patients with wrist pathology.Patients and methods.- Fifty-one patients (40 m, 11 w, mean age 42 years), 25 fractures of the radius and 26 lesions of the carpus.Questionnaires PRWE-F and DASH-F at entry and at discharge (0 to 100). Calculation of the construct validity of the PRWE-F comparing with the DASH-F with Pearson correlation coefficients (r) at entry and at discharge. Level of significance (alpha) was set at 5%.Results.- Correlation DASH/PRWE at entry: r = 0.799 (95% CI 0.671 to 0.881), P < 0.0001. Correlation DASH/PRWE at discharge: r = 0.847 (95% CI: 0.745 to 0.910), P < 0.0001.Discussion.- The construct validity of the two instruments indicates that they measure the same concept. Our correlation between DASH-F and PRWE-F, going from 0.799 to 0.847, are comparable to those published in different languages (0.71 to 0.84) [3,4]. The questionnaires PRWE-F can thus be used in rehabilitation patients presenting with wrist pathologies; it is comparable to the DASH but described by MacDermid [1] to be more specific. Compared to the DASH it has the advantage of consisting of two dimensions. Its construct validity is excellent. This questionnaire should be evaluated in other populations, and it should be compared with hand questionnaires more specific than the DASH.

Prevalence of the metabolic syndrome in the Seychelles according to different definitions, contribution of components, and agreement between different definitions

Background: The metabolic syndrome (MS) represents a cluster of metabolic disorders that predicts diabetes and cardiovascular disease. Several definitions exist and further descriptive and prospective data are needed to compare these definitions and their significance in different populations. Objective: We examined, in a country of the African region, i) the prevalence of MS according to three major definitions (ATP, IDF, WHO); ii) the contribution of individual MS components; and iii) the agreement between the three considered definitions. We also examined the prevalence among diabetics and non-diabetics. Methods: We conducted an examination survey in a sample representative of the general population aged 25-64 of the Seychelles (Indian Ocean, African region), attended by 1255 persons (participation rate of 80.2%). Results: The prevalence of MS was similar with either definition of MS in men (24%--25%) but differed in women (WHO: 25%, ATP: 32%; IDF: 35%). Upon exclusion of diabetic persons, the prevalence was 5-10% lower for all three MS definitions: most diabetic persons had MS although a substantial proportion of diabetic men aged 45--64 did not have MS. The following components were found most often among persons with MS: 90% had high blood pressure (HBP) and 78% had obesity (ATP); 95% had obesity and 84% had HBP (WHO), and 89% had HBP and 75% had impaired glucose regulation (IDF) - not considering impaired glucose regulation and obesity that are compulsory components of the WHO and IDF definitions, respectively. Among persons with MS based on either of the three definitions (37% of total population), less than 80% met both ATP and IDF criteria, 67% both WHO and IDF criteria, 54% both WHO and ATP criteria and only 37% met all three definitions. Conclusion: We found a fairly high prevalence of MS in an African population. However, because there was only poor agreement between the 3 MS definitions, the fairly similar proportions of MS based on ATP, IDF or WHO definitions identified, to a substantial extent, different subjects as having MS.

Validation of the German version of the Career Adapt-Abilities Scale and its relation to orientations to happiness and work stress

Career adapt-ability has recently gained momentum as a psychosocial construct that not only has much to offer the field of career development, but also contributes to positive coping, adjustment and self-regulation through the four dimensions of concern, control, curiosity and confidence. The positive psychology movement, with concepts such as the orientations to happiness, explores the factors that contribute to human flourishing and optimum functioning. This research has two main contributions; 1) to validate a German version of the Career Adapt-Abilities Scale (CAAS), and 2) to extend the contribution of adapt-abilities to the field of work stress and explore its mediating capacity in the relation between orientations to happiness and work stress. We used a representative sample of the German-speaking Swiss working population including 1204 participants (49.8% women), aged between 26 and 56 (Mage = 42.04). Results indicated that the German version of the CAAS is valid, with overall high levels of model fit suggesting that the conceptual structure of career adapt-ability replicates well in this cultural context. Adapt-abilities showed a negative relationship to work stress, and a positive one with orientations to happiness. The engagement and pleasure scales of orientations to happiness also correlated negatively with work stress. Moreover, career adapt-ability mediates the relationship between orientations to happiness and work stress. In depth analysis of the mediating effect revealed that control is the only significant mediator. Thus control may be acting as a mechanism through which individuals attain their desired life at work subsequently contributing to reduced stress levels.

Regulation of the akt signalling in human skeletal muscle atrophy

Abstract : The term "muscle disuse" is often used to refer collectively to reductions in neuromuscular activity as observed with sedentary lifestyles, reduced weight bearing, cancer, chronic obstructive pulmonary disease, chronic heart failure, spinal cord injury, sarcopenia or exposure to microgravity (spaceflight). Muscle disuse atrophy, caused by accelerated proteolysis, is predominantly due to the activation of the ATP-dependent ubiquitin (Ub) proteasome pathway. The current advances in understanding the molecular factors contributing to the Ub-dependent proteolysis process have been made mostly in rodent models of human disease and denervation with few investigations performed directly in humans. Recently, in mice, the genes Atrogin-1 and MuRF1 have been designated as primary candidates in the control of muscle atrophy. Additionally, the decreased activity of the Akt/GSK-3ß and Akt/mTOR pathways has been associated with a reduction in protein synthesis and contributing to skeletal muscle atrophy. Therefore, it is now commonly accepted that skeletal muscle atrophy is the result of a decreased protein synthesis concomitant with an increase in protein degradation (Glass 2003). Atrogin-1 and MuRF1 are genes expressed exclusively in muscle. In mice, their expression has been shown to be directly correlated with the severity of atrophy. KO-mice experiments showed a major protection against atrophy when either of these genes were deleted. Skeletal muscle hypertrophy is an important function in normal postnatal development and in the adaptive response to exercise. It has been shown, in vitro, that the activation of phosphatidylinositol 3-kinase (PI-3K), by insulin growth factor 1 (IGF-1), stimulates myotubes hypertrophy by activating the downstream pathways, Akt/GSK-3ß and Akt/mTOR. It has also been demonstrated in mice, in vivo, that activation of these signalling pathways causes muscle hypertrophy. Moreover, the latter were recently proposed to also reduce muscle atrophy by inhibiting the FKHR mediated transcription of several muscle atrophy genes; Atrogin-1 and MuRF1. Therefore, these targets present new avenues for developing further the understanding of the molecular mechanisms involved in both skeletal muscle atrophy and hypertrophy. The present study proposed to investigate the regulation of the Akt/GSK-3ß and Akt/mTOR signalling pathways, as well as the expression levels of the "atrogenes", Atrogin-1 and MuRF1, in four human models of skeletal muscle atrophy. In the first study, we measured the regulation of the Akt signalling pathway after 8 weeks of both hypertrophy stimulating resistance training and atrophy stimulation de-training. As expected following resistance training, muscle hypertrophy and an increase in the phosphorylation status of the different members of the Akt pathway was observed. This was paralleled by a concomitant decrease in FOXO1 nuclear protein content. Surprisingly, exercise training also induced an increase in the, expression of the atrophy genes and proteins involved in the ATP-dependant ubiquitin-proteasome system. On the opposite, following the de-training period a muscle atrophy, relative to the post-training muscle size, was measured. At the same time, the phosphorylation levels of Akt and GSK-3ß were reduced while the amount of FOXO1 in the nucleus increased. After the atrophy phase, there was also a reduction in Atrogin-1 and MuRF1 contents. In this study, we demonstrate for the first time in healthy human skeletal muscle, that the regulation of Akt and its downstream targets GSK-3ß, mTOR and FOXO1 are associated with both thé skeletal muscle hypertrophy and atrophy processes. Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease characterized by the loss of both upper and lower motor neurons, which leads to severe muscle weakness and atrophy. All measurements were performed in biopsies from 22 ALS patients and 16 healthy controls. ALS patients displayed an increase in Atrogin-1 mRNA and protein content which was associated with a decrease in Akt activity. However there was no difference in the mRNA and phospho-protein content of FOXO1, FOXO3a, p70S6K and GSK-3ß. The transcriptional regulation of human Atrogin-1 may be controlled by an Akt-mediated transcription factor other than FKHR or via an other signalling pathway. Chronic complete spinal cord injury (SCI) is associated with severe muscle atrophy which is linked to co-morbidity factors such as diabetes, obesity, lipid disorders and cardiovascular diseases. Molecular mechanisms associated with chronic complete SCI-related muscle atrophy are not well understood. The aim of the present study was to determine if there was an increase in catabolic signalling targets such as Atrogin-1, MuRF1, FOXO and myostatin, and decreases in anabolic signalling targets such as IGF, Akt, GSK-3ß, mTOR, 4E-BP1 and p-70S6K in chronic complete SCI patients. All measurements were performed in biopsies taken from 8 complete chronic SCI patients and 7 age matched healthy controls. In SCI patients when compared with controls, there was a significant reduction in mRNA levels of Atrogin1, MuRF1 and Myostatin. Protein levels for Atrogin-1, FOX01 and FOX03a were also reduced. IGF-1 and both phosphorylated GSK-3ß and 4E-BP1 were decreased; the latter two in an Akt and mTOR independent manner, respectively. Reductions in Atrogin-1, MuRF1, FOXO and myostatin suggest the existence of an internal mechanism aimed at reducing further loss of muscle proteins during chronic SCI. The downregulation of signalling proteins regulating anabolism such as IGF, GSK3ß and 4E-BP1 would reduce the ability to increase protein synthesis rates in this chronic state of muscle wasting. The molecular mechanisms controlling age-related skeletal muscle loss in humans are poorly understood. The present study aimed to investigate the regulation of several genes and proteins involved in the activation of key signalling pathways promoting muscle hypertrophy such as GH/STAT5/IGF, IGF/Akt/GSK-3ß/4E-BP1 and muscle atrophy such as TNFα/SOCS3 and Akt/FOXO/Atrogin-1 or MuRF1 in muscle biopsies from 13 young and 16 elderly men. In the older, as compared with the young subjects, TNFα and SOCS-3 were increased while growth hormone receptor protein (GHR) and IGF-1 mRNA were both decreased. Akt protein levels were increased however no change in phosphorylated Akt content was observed. GSK-3ß phosphorylation levels were increased while 4E-BP1 was not changed. Nuclear FKHR and FKHRL1 protein levels were decreased, with no changes in their atrophy target genes, Atrogin-1 and MuRF1. Myostatin mRNA and protein levels were significantly elevated. Human sarcopenia may be linked to a reduction in the activity or sensitivity of anabolic signalling proteins such as GHR, IGF and Akt. TNFα, SOCS-3 and myostatin are potential candidates influencing this anabolic perturbation. In conclusion our results support those obtained in rodent or ín vitro models, and demonstrate Akt plays a pivotal role in the control of muscle mass in humans. However, the Akt phosphorylation status was dependant upon the model of muscle atrophy as Akt phosphorylation was reduced in all atrophy models except for SCI. Additionally, the activity pattern of the downstream targets of Akt appears to be different upon the various human models. It seems that under particular conditions such as spinal cord injury or sarcopenia, .the regulation of GSK-3ß, 4eBP1 and p70S6K might be independent of Akt suggesting alternative signalling pathways in the control of these the anabolic response in human skeletal muscle. The regulation of Atrogin-1 and MuRF1 in some of our studies has been shown to be also independent of the well-described Akt/FOXO signalling pathway suggesting that other transcription factors may regulate human Atrogin-1 and MuRF1. These four different models of skeletal muscle atrophy and hypertrophy have brought a better understanding concerning the molecular mechanisms controlling skeletal muscle mass in humans.

Psychometric properties of the French version of the Zuckerman-Kuhlman Personality Questionnaire

This instrumental study was designed to investigate the psychometric properties of the French version and the cross-language replicability of the Zuckerman-Kuhlman Personality Questionnaire (ZKPQ) at the factor- and at the facet-level. The ZKPQ is an instrument aimed at assessing the five basic factors of Zuckerman's Alternative Five-Factor Model (AFFM). Subjects were 843 French-speaking Swiss, mainly students. At the factor-level, the reliability ranged from .73 to .87 and at the facet level, the reliability ranged from .57 to .77. Differences between genders are congruent with those found in the American sample. Women scored higher on N-Anx, and lower on ImpSS, and Act. A series of exploratory factor analyses supported the overall five-factor structure and the structure at the facet-level. The correlations among the scales support that the five basic factors of the AFFM are orthogonal. Targeted factor analyses and congruence coefficients show high cross-language replicability at the factor- and at the facet-level. The adequacy of the model at the factor- and facet-level was tested using confirmatory factor analyses. The results show that the French version of the ZKPQ is a reliable and valid instrument and has a high cross-language replicability.

French version of the addiction severity index (5th Edition): validity and reliability among Swiss opiate-dependent patients. French validation of the Addiction Severity Index.

OBJECTIVE: The aim of the study was to validate a French adaptation of the 5th version of the Addiction Severity Index (ASI) instrument in a Swiss sample of illicit drug users. PARTICIPANTS AND SETTING: The participants in the study were 54 French-speaking dependent patients, most of them with opiates as the drug of first choice. Procedure: Analyses of internal consistency (convergent and discriminant validity) and reliability, including measures of test-retest and inter-observer correlations, were conducted. RESULTS: Besides good applicability of the test, the results on composite scores (CSs) indicate comparable results to those obtained in a sample of American opiate-dependent patients. Across the seven dimensions of the ASI, Cronbach's alpha ranged from 0.42 to 0.76, test-retest correlations coefficients ranged from 0.48 to 0.98, while for CSs, inter-observer correlations ranged from 0.76 to 0.99. CONCLUSIONS: Despite several limitations, the French version of the ASI presents acceptable criteria of applicability, validity and reliability in a sample of drug-dependent patients.

Food allergy: Validation of the French version of the FAQLQ-PF Quality of Life Questionnaire

Background: It has been previously shown with English speaking children that food allergy clearly affects their quality of life. The first allergy quality of life questionnaire has been validated in English in 2008, however to date no questionnaire was available in French. Objectives: To validate the French version of the Food Allergy Quality of Life Questionnaire- Parent Form (FAQLQ-PF) already existing version developed and validated in English by DunnGalvin et al. Methods: The questionnaire was translated from English to French by two independent French-speaking translators and retranslated by an independent English-speaking translator. We then recruited 30 patients between 0 and 12 years with a food allergy. Parents of these children answered the questionnaire during a clinic visit. The results obtained were then analysed and compared with the results provided by DunnGalvin's study and the Food Allergy independent Measure (FAIM). Results: 27 questionnaires were fully completed and available for analysis. Median age was 6 years with a range from 18 months to 12 years. We had a girl/boy ratio of 1:1.14. A Cronbach's a correlation index of 0.748 was found. Validity was demonstrated by significant correlations between FAQLQ-PF and the FAIM. Conclusion: The French version of the FAQLQ was validated and will permit to assess degree of Quality of Life for French-speaking children with food allergy. It will be an important tool for clinical research and will allow research collaboration between French and English speaking research teams.
