The Multiple Sclerosis-Fatigue Self- Efficacy (MS-FSE) scale: initial validation

Self-Report Measures of Fatigue for People With Multiple Sclerosis: A Systematic Review

BACKGROUND AND PURPOSE

The symptom of fatigue impairs function in people with multiple sclerosis (MS). Choosing appropriate measures to assess fatigue is challenging. The purpose of this article is to report the findings of a systematic review of patient-reported fatigue measures for people with MS.

METHODS

PubMed, CINAHL, and Embase databases were searched through January 2020 using terms related to fatigue and MS. Studies were included if the sample size was 30 or more or smaller samples if adequately powered, and if information about measurement characteristics (ie, test-retest reliability, content validity, responsiveness, interpretability, or generalizability) of the measure(s) could be extracted. Study quality was appraised with the 2-point COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) checklist. Data about measurement characteristics, psychometrics, and clinical utility were extracted and results were synthesized.

RESULTS

Twenty-four articles met inclusion criteria with information about 17 patient-reported fatigue measures. No studies had critical methodologic flaws. Measurement characteristic data were not available for all measures. Clinical utility varied in time to complete and fatigue domains assessed.

DISCUSSION AND CONCLUSIONS

Five measures had data pertaining to all properties of interest. Of these, only the Modified Fatigue Impact Scale (MFIS) and Fatigue Severity Scale (FSS) had excellent reliability, responsiveness data, no notable ceiling/floor effects, and high clinical utility. We recommend the MFIS for comprehensive measurement and the FSS for screening of subjective fatigue in people with MS.Video Abstract available for more insights from the authors (see the Video, Supplemental Digital Content 1, available at: http://links.lww.com/JNPT/A443 ).

Self-efficacy training as an adjunct to exercise in a person with progressive multiple sclerosis: a case report

Background: Increasing self-efficacy to exercise and minimizing disease-related barriers has been shown to improve physical activity levels and quality of life (QOL) in persons with multiple sclerosis (MS). Currently, little research has examined exercise self-efficacy in persons with more advanced MS. Purpose: Explore the effects of a self-efficacy plus exercise intervention on physical activity endurance and level, QOL, and fatigue in an individual with advanced MS and low self-efficacy.Methods: The participant was a 60-year-old, severely disabled female with secondary progressive MS and an Expanded Disability Status Score (EDSS) of 8. The 8-week intervention consisted of weekly discussions and MS-related education; four one-on-one sessions with a MS "mentor;" daily journal to record sleep quality, fatigue level, and physical activity. Outcomes included a modified 5-meter walk test (5MWT), MS Impact Scale (MSIS-29), Exercise Self-Efficacy Scale (EX-ES), Modified Fatigue Impact Scale (MFIS), MS Self-Efficacy Scale (MS-SES), Patient Health Questionnaire-9 (PHQ-9), and daily physical activity monitoring. Outcomes were assessed at baseline (week 0), post-intervention (week 8), and 8 weeks post intervention (week 16). The participant continued her regular exercise routine independently throughout the study period.Results: There were notable improvements in EX-ES, MFIS, PHQ-9, MSIS-29 psychological subscale, sleep quality, and morning fatigue ratings post intervention, some of which were retained at follow up.Conclusion: The findings illustrate that an 8-week self-efficacy intervention increased exercise self-efficacy, QOL, and reduced perceived fatigue in a severely disabled individual with progressive MS. Future research should examine self-efficacy interventions in a larger sample size of persons with progressive MS.

The Perimenopausal Fatigue Self-Management Scale Is Suitable for Evaluating Perimenopausal Taiwanese Women's Vulnerability to Fatigue Syndrome

The purpose of this study was to test the feasibility of utilizing the established perimenopausal fatigue self-management scale (P-MFSMS) to evaluate perimenopausal Taiwanese women's vulnerability to fatigue syndrome. A cross-sectional study design was adopted to survey 220 perimenopausal Taiwanese women with a mean age of 51.8 ± 4.64 years and a mean body mass index of 23.07 ± 3.04 kg/m2, 75.9% of whom were married, 52.3% had a college education or above, 80.4% had salaries, 81.3% had small families, and 96.4% were not using hormone therapy. The P-MFSMS consists of 25 questions based on six categories: (1) strive to maintain work energy and efficiency; (2) seek self-help from medical resources (doctor shopping); (3) strive to maintain the normal operation of the family (seeking help and support from family or significant other); (4) make time for activities or exercise in busy life; (5) slow down or adjust lifestyle; (6) frustration. For all of these six categories, the minimum loading of each question on the factor was calculated to be over 0.50, with a Cronbach's α of 0.78 and a corrected total-item correlation of >0.50. The goodness of fit of the model was determined to be acceptable, with a chi-square/df value of <3.0 (χ2 = 503.45 and df = 260), a root mean square error of approximation (RMSEA) value of 0.065 (<0.08), as well as a Kaiser-Meyer-Olkin (KMO) value of 0.892. The Tucker-Lewis index (TLI = 0.91), Comparative Fit index (CFI = 0.92), and Incremental Fit index (IFI = 0.92) were all >0.90. There was no statistically significant difference in the difficulty between perimenopausal and postmenopausal women utilizing differential item function (DIF) analysis. Taken together, the 25-question P-MFSMS may be a potentially valid and reliable instrument for suitably evaluating perimenopausal Taiwanese women's vulnerability to fatigue syndrome. Future studies will be conducted to test the effectiveness of the P-MFSMS for evaluating perimenopausal Taiwanese women's vulnerability to fatigue syndrome in clinical practice.

Outcome measures for physical fatigue in individuals with multiple sclerosis: a systematic review

INTRODUCTION

Physical fatigue can be a common reason for early retirement or sick leave since it appears in the earliest stages of multiple sclerosis (MS). Therefore, a prompt and accurate diagnosis is essential. This systematic review aims to identify and describe the instruments used to assess physical fatigue in MS patients with consideration for the languages used to validate the instruments and their methodological qualities.

AREA COVERED

This study has been carried out through 'Medline,' 'Scopus,' 'Cinhal,' and 'Web of Science' databases for all the papers published before 24 January 2020. Three independent authors have chosen the eligible studies based upon pre-set criteria of inclusion. Data collection, data items, and assessment of the risk of bias: the data extraction approach was chosen based on the Cochrane Methods. For data collection, the authors followed the recommendations from the COSMIN initiative. Study quality and risk of bias were assessed using the COSMIN Check List.

EXPERT OPINION

119 publications have been reviewed. The 45 assessment scales can be divided into specific scales for physical fatigue and specific scales for MS. The most popular tools are the Fatigue Severity Scale and the Modified Fatigue Impact Scale.

Psychometric properties of the newly developed Physician Teaching Self-Efficacy Questionnaire (PTSQ)

BACKGROUND

High teaching quality and students' corresponding learning progress are the most important indicators of teachers' work performance. Theory and numerous empirical studies indicate that self-efficacy, a person's belief in her or his ability to accomplish a task, is an important predictor of work performance. Accordingly, it can be assumed that teaching self-efficacy also influences teaching performance and students' learning progress with regard to physicians who teach in undergraduate medical education. Therefore, the aim of this study was to develop and validate an instrument measuring clinical teaching self-efficacy in physicians.

METHODS

We developed 16 items reflecting physicians' beliefs to provide high quality clinical teaching when facing regularly occurring critical teaching situations. These constitute the Physician Teaching Self-Efficacy Questionnaire (PTSQ). For its validation, we used data from a sample of 247 physicians from internal medicine and surgery at six German medical faculties. Regarding factorial validity, we performed exploratory structural equation modelling (ESEM) as well as confirmatory factor analysis (CFA). Regarding criterion validity, correlations with the scales of the Physician Teaching Motivation Questionnaire (PTMQ), teaching experience and perceived teaching involvement were calculated. Additionally, we conducted the same analyses with a short 6-item version.

RESULTS

ESEM delivered evidence for a three-factor structure with a superordinate general factor, which was confirmed by local and global fit indicators in CFA (RMSEA = .055, TLI = .939, SRMR = .048, CFI = .948). We identified the following three subfactors: teaching self-efficacy with respect to self-regulation, dyadic regulation involving students, and triadic regulation involving students and patients. Internal consistencies indicated acceptable to excellent reliability for all scales (Cronbach's alpha = .77-.90). Theory-consistent correlations with the PTMQ scales, teaching experience, and teaching involvement confirmed criterion validity. Besides excellent global fit, the short version of the PTSQ also fulfilled all other validity criteria.

CONCLUSIONS

The PTSQ is a valid instrument to assess physicians' clinical teaching self-efficacy. It could be used in faculty development programmes and for educational research. The short version could be used in situations that are time-critical for physicians in order to ensure high response rates.

Effect of a self-management and follow-up program on self-efficacy in patients with multiple sclerosis: a randomized clinical trial

Background:

Multiple sclerosis (MS) is the most common autoimmune disorder of the central nervous system with profound effects on patients’ independence and self-efficacy. Then, it is still questionable whether self-management programs in patients with MS affect the patients’ self-efficacy.

Objectives:

The present study aimed to investigate the effect of a self-management program plus regular follow-up on self-efficacy in patients with MS.

Patients and Methods:

A quasi-experimental study was performed on 80 patients with relapsing remitting MS who were randomly allocated to an intervention (n = 40) and a control group (n = 40). The MS self-efficacy scale was completed before and after the intervention. The intervention group was divided into four small subgroups of ten. Then, each subgroup was invited to participate in four training sessions about self-management. During the two months after the self-management sessions, a weekly telephone follow-up was conducted for each patient in the intervention group. The control group did not receive any intervention other than routine care. Data were analyzed using SPSS 11.5. Descriptive statistics, Chi-square, and independent-samples t-testes were used to analyze the data.

Results:

No significant difference in mean scores of baseline self-efficacy was found between the control (52.90 ± 8.03) and the intervention groups (54.90 ± 9.51) (P = 0.313). However, a significant difference was observed between the control (50.90 ± 5.71) and the intervention groups (59.80 ± 5.27) regarding mean scores of self-efficacy at the end of the study (P < 0.001).

Conclusions:

Implementing the self-management program plus regular follow-up increased the perception of self-efficacy in patients with MS. Similar self-management programs are recommended to be integrated in the regular caring of patients with MS.
