Repeatability and Reliability of the Rheumatoid Arthritis Foot Disease Activity Index in Spanish Patients: A Transcultural Adaptation

Translation, cross-cultural adaptation, and validation of the Greek version of the Multiple Sclerosis Intimacy and Sexuality Questionnaire-19

INTRODUCTION

Multiple Sclerosis Intimacy and Sexuality Questionnaire-19 (MSISQ-19) explores optimally impact of MS on sexual activity/satisfaction/intimacy.

AIM

The present study aims to provide the only validation of the Greek Version of MSISQ-19, and compare results to validation studies in other languages.

METHODS

The original/English version of the MSISQ-19 was translated into Greek according to standardized guidelines, while validity/reliability, correlations with other scales and sexual dysfunction prevalence were tested. Subjects were requested to complete all questionnaires and MSISQ-19, being re-tested three weeks later. Construct-validity of the Greek version of the MSISQ-19 was confirmed with principal-component-analysis. Bartlett's test assessed correlation-adequacy between items. Pearson's correlation explored internal-construct-validity between subscales and overall score, and external-construct-validity with disease-status variables, cognitive testing and patient-reported outcomes regarding fatigue, depression/anxiety, MS impact, and quality of life.

RESULTS

201 PwMS (130 female). Mean age was 39.3 ± 11.8 years with median disease-duration 11.7 ± 7.9 years. 79.1% RRMS, PPMS (10.4%) and SPMS (10.4%). Cronbach's alpha coefficient was 0.949. MSISQ-19 correlations between items were large. Significant associations of sexual dysfunction were identified with age (rho = 0.392, p < 0.01), years of education (rho=-0.199, p = 0.006), the Expanded Disability Status Scale (rho = 0.518, p < 0.01) and MS duration (rho = 0.354, p < 0.01). Correlations were disclosed with the Brief International Cognitive Assessment for MS (rho=-0.247, p < 0.05), Modified Fatigue Impact Scale (rho = 0.374, p < 0.05), Depression Anxiety Stress Scale (rho = 0.375, p < 0.05), Multiple Sclerosis Impact Scale (rho = 0.442, p < 0.05), and EuroQoL-five-dimensional instrument (rho = 0.375, p < 0.05). Internal consistency of the Greek version of the MSISQ-19 was confirmed with Cronbach's alpha. Test-retest reliability (31 PwMS) was excellent with intraclass-correlation-coefficients > 0.90.

CONCLUSION

Besides Greek MSISQ-19 satisfactory validity/reliability/reproducibility and being first to include cognitive-testing, authors estimated sexual-dysfunction prevalence affecting half PwMS.HIGHLIGHTSThis study provides the only validation of the Greek Version of the MSISQ-19.The latter was found with satisfactory validity, reliability and reproducibility.50% of the Greek PwMS sample was found to be afflicted with sexual dysfunction.This is also the first validation study to examine associations with cognitive testing.Sexual function is still an underestimated functionality parameter upon examination.

Repeatability and reliability of the footwear assessment tool in Spanish patients: A transcultural adaptation

BACKGROUND

The footwear assessment tool was designed to advise an appropriate footwear for each situation and patient. Footwear alterations structures can influence in musculoskeletal disorders, developing foot ulcers, increase the peak plantar pressure, bacterial growth, low back pain.

METHODS

To validate the study 101 subjects were recruited. The study was tested by two expert podiatrists using the tool for the assessment of footwear characteristics that is composed by five domains, fit, general features, general structure, motion control properties and cushioning system. Each domain analyzes different shoe items.

RESULTS

An excellent agreement between the test-retest. A suitable Cronbach's α was suggested for the five domains of fit (α = 0.952), general features (α = 0.953), general structure (α = 0.947), motion control properties (α = 0.951), and cushioning system (α = 0.951). Test-retest reliability was excellent for all domains. There were no significant differences between any domain (p > 0.05). There was only statistically significant difference in the item forefoot height (p = 0.011). For all the domains items there were no statistically significant difference (p > 0.05).

CONCLUSIONS

The tool for the assessment European footwear is a suitable repeatability and reliability footwear tool that can be used in Spanish language subjects.

IGBO Version of the Older People's Quality Of Life Questionnaire (OPQOL-35) Is Valid and Reliable: Cross-Cultural Adaptation and Validation

To translate, cross-culturally adapt, and psychometrically evaluate the Older People's Quality of Life Questionnaire (OPQOL-35) among the Igbo older adult population in Enugu State. The original English OPQOL-35 (E-OPQOL-35) was translated into Igbo language, synthesized, back translated, and subsequently subjected to expert panel review, pre-testing and cognitive debriefing interview. The final Igbo version (I-OPQOL-35) was tested for internal consistency, concurrent, and structural validities in a cross-sectional study of 115 consenting apparently healthy older adults that were conveniently recruited from Enugu State, at 0.05 level of significance. The Spearman correlation coefficients between the participants' domain and total scores on the I-OPQOL-35 and E-OPQOL-35 (rho = .92-1.00) were excellent. The Mann-Whitney U test revealed no significant difference between corresponding scores in the E-OPQOL-35 and I-OPQOL-35 (P = .65-.94). The internal consistency coefficient of the I-OPQOL-35 was 0.78. The ceiling and floor effects were 0% respectively. The I-OPQOL-35 is therefore a valid and reliable instrument for the assessment of quality of life among Igbo older adults in Nigeria.
