Development, initial content validation and reliability of Nigerian composite lifestyle CVD risk factors questionnaire for adolescents.

BACKGROUND Cardiovascular disease risk (CVD) factors affect every age category including adolescents in developing nations. Prevention strategies are effective only when there are epidemiological data for the targeted populations. The collection of such data is only made easy with composite lifestyle CVD risk factors measures that are culturally sensitive and acceptable among the target populations. OBJECTIVE The objective of the study was to develop a culturally sensitive and friendly composite lifestyle CVD risk factors questionnaire for adolescents in Nigeria. METHODS A systematic review was conducted to identify existing, published questionnaires from which items could be selected. Content and face validation were conducted using an expert panel and a sub-sample of the target population. Data was analyzed qualitatively and reliability was assessed using intra-class correlation and Kappa statistic. RESULTS Based on the comments received from experts, the questions were restructured, simplified, clarified, formatted, some questions were added and expert reached a consensus. Kappa showed fair to moderate agreement in 65% of the questions and perfect agreement in one question. CONCLUSION The CVD risk factors questionnaire has acceptable content validity and reliability and should be used to assess CVD risk factors among adolescents in Nigeria.

Nigerian (Yoruba) version of Disabilities of the Arm, Shoulder and Hand questionnaire (DASH-Y): Cross-cultural adaptation and initial validation

Introduction The Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire is a widely used upper extremity outcome measure. However, it is yet to be translated into any of the major languages in Nigeria, thus limiting its utility in the Nigerian clinical setting. The aim of this study was to cross-culturally adapt the DASH questionnaire into Yoruba, a major Nigerian language and investigate its initial validation. Methods The English version of DASH was adapted into Yoruba through forward–back translations, experts’ committee meetings, pretesting and cognitive debriefing interview in accordance with the guidelines recommended by the developers of DASH. Fifty-two purposively selected patients with upper extremity musculoskeletal disorders participated in a cross-sectional survey. Factor analysis was performed to ensure structural validity of Yoruba version, and construct validity was investigated with Spearman rank correlation coefficient. Results The Yoruba version of DASH has semantic, idiomatic, linguistic and conceptual equivalence with the English DASH. Thirty linear components were identified within the data set. Principal factor analysis of the Yoruba DASH revealed a seven factor scale, having fulfilled all the necessary conditions. The Kaiser-Meyer-Olkin measure of sampling adequacy was 0.61, and Barlett’s test of Sphericity was adequate and significant (χ2 (1066) = 435, p = 0.001). Significant correlation (r = 0.994, p = 0.001) exists between scores obtained on English and Yoruba versions of DASH. Conclusion A cross-culturally adapted, valid Yoruba version of DASH is available for use in in south western Nigeria and other similar populations.

Factors influencing the use of outcome measures in knee osteoarthritis: A mixed method study of physiotherapists in Nigeria

ABSTRACT Background: Osteoarthritis (OA) of the knee constitutes a significant proportion of musculoskeletal disorders managed in physiotherapy clinics worldwide. Best practice guidelines in the management of OA ensure the use of outcome measures. Aim: This study explored the factors influencing the use of outcome measures in management of patients with knee OA among physiotherapists in southwestern Nigeria. Methods: Mixed method design was used that involved a cross-sectional survey of 77 purposively selected physiotherapists and a focus group discussion with another 6 physiotherapists. Results: Participants (48 males, 29 females) were aged 35.3 ± 7.3 years. Fifty-two (67.5%) participants reported the use of outcome measures in the treatment of the patients with knee OA. The perceived barriers reported were lack of time/heavy workload (55.9%); lack of standardization of outcome measures (45%); lack of motivation (36.4%); and nonavailability of outcome measures in the clinic (36.4%). Reported perceived facilitators include interest/need to track patient’s progress and ethical practice (87.1%); familiarity with outcome measures (87.0%); and understanding of the benefits of using outcome measures (87.0%). Conclusion: There is a need to establish good organizational structure focusing on the use of outcome measures in practice and development of a concessional toolkit of short and easily applicable instruments with user description.

Physiotherapy clinical students’ perception of their learning environment: A Nigerian perspective

Background. A favourable environment has a positive and significant impact on students’ learning, academic progress and well-being. The present study was undertaken to identify the perceptions of physiotherapy students in their clinical years of their learning environment at the College of Medicine, University of Ibadan, Nigeria. Methods. A focus group discussion involving 12 undergraduate physiotherapy students was used to obtain information about their perception of their learning environment. Six students from two clinical levels of study were recruited through a simple random sampling technique. The focus interview guide was developed based on information obtained from the DREEM questionnaire and literature review. The interviews were analysed using the identified themes from DREEM and grounded theory for emerging subcategories. Results. Five descriptive themes and several subcategories were identified: ( i ) context of learning (course objectives, student focused/teacher centred, active learning); ( ii ) context of teachers (knowledgeable teachers, provision of formative assessment, approachable lecturers, cordial teacher-student relationship); ( iii ) context of students’ perception of their academic skills (understanding the subject); ( iv ) context of atmosphere (adequacy of facilities, e.g. chairs, classrooms, library, books); and ( v ) context of social life (religious activities, social functions, school-related social activities). Conclusion. Most students perceived their learning environment as good, especially with regard to student-teacher relationships. Some of the teachers were described as knowledgeable, and as providing formative assessment. However, students perceived their learning as being teacher centred. To facilitate an excellent learning environment, particular attention needs to be paid to availability of physiotherapy textbooks in the college library, sufficient appropriate furniture in classrooms, and provision of a functioning departmental library. The findings from this study may provide insights for teachers who wish to enhance the effectiveness of their teaching and of their students’ learning.
