German translation, cultural adaption and validation of the unidimensional self-efficacy scale for multiple sclerosis: a study protocol.

ABSTRACT:

Introduction

Self-efficacy refers to individuals' confidence in their ability to perform relevant tasks to accomplish desired goals. This is independent of their actual abilities. In people with multiple sclerosis (MS), self-efficacy has been shown to powerfully influence motivation and health-related behaviour, such as adherence to prescribed treatment or physical activity. So far, a rigorously tested German language self-efficacy questionnaire for people with MS is missing.

Methods

The purpose of this study is to translate the original Unidimensional Self-Efficacy Scale for Multiple Sclerosis (USE-MS) into German and to validate the German USE-MS (USE-MS-G). Based on Bandura's concept of self-efficacy and international guidelines for questionnaire development, the patient-led development of the pre-final German version will involve a forward-backward translation process, synthesis of translations, expert committee review and consensus with the original test developers. At two centres in Tyrol, Austria, content and face validity and cultural adaption for Austria will be established using face-to-face semistructured cognitive interviews of 30 people with MS (PwMS). A further 292 PwMS with minimal to severe disability will be tested at two timepoints to validate the USE-MS-G.

Results

Mixed methods analyses will be applied. Interviews will be transcribed and analysed employing qualitative content analysis. External validity will be explored using Spearman's Rank correlation coefficients of the USE-MS-G with the 13-item Resilience Scale, General Self-Efficacy Scale, Multiple Sclerosis International Quality of Life questionnaire, Hospital Anxiety and Depression Scale and MS-specific Neurological Fatigue Index. Test-retest reliability, internal consistency and floor and ceiling effects will be evaluated. Internal validity will be examined using Rasch analysis.

Ethics and dissemination

Ethical approval was received from the Ethics Committee of the Medical University of Innsbruck, Austria (reference number EK1260/2018; 13.12.2018). Results from this study will be disseminated to the participants and MS Societies, and to clinicians and researchers through peer-reviewed publications and conferences.

Project description:BackgroundSelf-efficacy concerns individuals' beliefs in their capability to exercise control in specific situations and complete tasks successfully. In people with multiple sclerosis (PwMS), self-efficacy has been associated with physical activity levels and quality of life. As a validated German language self-efficacy scale for PwMS is missing the aims of this study were to translate the Unidimensional Self-Efficacy Scale for Multiple Sclerosis (USE-MS) into German, establish face and content validity and cultural adaptation of the German version for PwMS in Austria. A further aim was to validate the German USE-MS (USE-MS-G) in PwMS.MethodsPermission to translate and validate the USE-MS was received from the scale developers. Following guidelines for translation and validation of questionnaires and applying Bandura's concept of self-efficacy, the USE-MS was forward-backward translated with content and face validity established. Cultural adaptation for Austria was performed using cognitive patient interviews. Reliability was assessed using Cronbach's alpha, Person separation index and Lin's concordance correlation coefficient. Rasch analysis was employed to assess construct validity. Comparison was made to scales for resilience, general self-efficacy, anxiety and depression, multiple sclerosis fatigue and health-related quality of life. Data were also pooled with an historic English dataset to compare the English and German language versions.ResultsThe translation and cultural adaptation were successfully performed in the adaptation process of the USE-MS-G. Pretesting was conducted in 30 PwMS, the validation of the final USE-MS-G involved 309 PwMS with minimal to severe disability. The USE-MS-G was found to be valid against the Rasch model when fitting scale data using a bifactor solution of two super-items. It was shown to be unidimensional, free from differential item functioning and well targeted to the study population. Excellent convergent and known-groups validity, internal consistency, person separation reliability and test-retest reliability were shown for the USE-MS-G. Pooling of the English and German datasets confirmed invariance of item difficulties between languages.ConclusionThe USE-MS-G is a robust, valid and reliable scale to assess self-efficacy in PwMS and can generate interval level data on an equivalent metric to the UK version.Trial registrationISRCTN Registry; ISRCTN14843579 ; prospectively registered on 02. 01. 2019.

Project description:Objectives: The implementation of obstetric hybrid simulation and interprofessional collaboration between midwives and anesthetists in labor emergencies fostered the need to evaluate the impact of such a program. The original Interprofessional Attitude Scale (IPAS) assesses interprofessional attitudes among health professional students and includes the 2011 and 2016 Interprofessional Collaborative Practice report competency domains. The purpose of this study was to create a German version of the IPAS (G-IPAS) to use for the education of healthcare students. Methods: We performed the translation and validation of the IPAS in five steps: translation to German according to the International Society of Pharmaeconomics and Outcome Research guidelines; nine cognitive interviews with healthcare professionals and students;calculation of the Content Validity Index (CVI) by expert opinion; exploratory factor analysis (EFA); and internal consistency by Cronbach's alpha. All study participants gave written informed consent and the cantonal ethics committee waived further ethical approval. Results: The cognitive interviews led to replacement of single-item wording. We retained 27 items for CVI analysis. The averaged overall CVI was 0.79, with 15 items ?0.89. 185 students (70 medicine, 51 nursing, 48 physiotherapy, and 16 midwifery) contributed with data for the EFA and it produced three subscales. "Teamwork, roles, and responsibilities" with factor loadings ?0.49, "Patient-centeredness" with factor loadings ?0.31, and "Community-centeredness" with factor loadings ?0.57. Two items of the total scale were deleted, and four items were redistributed to another subscale. Cronbach's alpha for the overall G-IPAS scale was 0.87. After deleting and redistributing items in subscales, a new Scale-CVI/Average was calculated and was 0.82. Conclusions: Based on a rigorous validation process, the G-IPAS provides a reliable tool to assess attitudes towards interprofessional education among different healthcare professions in German-speaking countries.

Project description:BackgroundIn recent years, oral care for older people has received extensive attention in long-term care facilities. The Self-Efficacy for Providing Mouth Care (SE-PMC) and Attitudes for Providing Mouth Care (A-PMC) scale evaluated the self-efficacy and attitude of nursing staff while providing oral care. However, whether this scale is valid and reliable for Chinese nursing staff in China remains unverified. This study aims to translate the English version of SE-PMC and A-PMC into Chinese and determine their reliability and validity.MethodsAfter obtaining the author's consent, the procedure for a double-back translation and cross-cultural adaptation was conducted to develop the Chinese version of SE-PMC and A-PMC. The validity and reliability of the Chinese version of SE-PMC and A-PMC were evaluated in a cross-sectional observational study with 852 nurses from 42 Geriatric Care Facilities (GCFs). Exploratory factor analysis (EFA) (n = 427) and confirmatory factor analysis (CFA) (n = 425) were conducted to test the construct validity and quality of the factor structures. We applied the item discrimination test and homogeneity test for item analysis. Cronbach's alpha coefficient and split-half coefficient were adopted to evaluate internal consistency.ResultsThe Chinese version of SE-PMC (11 items, 3 factors) and A-PMC (11 items, 2 factors) included 22 items, reflecting adequate construct validity and reliability. In addition, test-retest reliability was 0.809 for SE-PMC and 0.811 for A-PMC, evincing good stability. The Cronbach's α coefficient of SE-PMC was 0.831, with each factor ranging from 0.793~0.906. The Cronbach's α coefficient of the A-PMC was 0.768, with each factor ranging from 0.814~0.824. Item-Content Validity Index (I-CVI) of SE-PMC and A-PMC ranged from 0.84 ~1.00 and 0.82~1.00, respectively.ConclusionThe Chinese version of SE-PMC and A-PMC was validated as a reliable assessment tool to evaluate the self-efficacy and attitude of nursing staff in GCFs for providing oral care in China.

Project description:Self-efficacy is central to community health workers' capacity and motivation to deliver evidence-based care; thus, validated measures of self-efficacy are needed to assess the effectiveness of community health worker programs. In this study, we culturally adapted and evaluated the General Self-Efficacy Scale among community health workers in Uganda using multiple methods. We adapted the ten-item General Self-Efficacy Scale through cross-cultural discussions within our multidisciplinary research team, translation from English into Luganda and back-translation into English, and six cognitive interviews with community health workers. We administered the adapted scale in a staged, two-part cross-sectional study, including a total of 147 community health workers. Exploratory factor analysis yielded three factors, which we labeled problem-solving, persistence, and resourcefulness. This three-factor solution had good model fit (standardized root mean square residual = 0.07) and explained 53.4% of the variance. We found evidence of convergent validity, as scores for the total scale were positively correlated with years of experience (r = 0.48; p < .001) and perceived social support (r = 0.39, p < .001). Scores were also higher among those with higher educational attainment in one-way analysis of variance and Bonferroni-corrected post hoc tests [F (2,72) = 9.16, p < .001]. We also found evidence of discriminant validity, as scores for the total scale were not correlated with age (r = - 0.07, p = .55), in agreement with literature showing that general self-efficacy is an age-independent construct. The internal consistency of the adapted scale was within the acceptable range for a pilot study (Cronbach's α = 0.61). This evaluation of a Uganda-adapted General Self-Efficacy Scale demonstrated promising psychometric properties; however, larger studies with repeated measures are warranted to further assess the adapted scale's factor structure, validity, reliability, and stability over time.
