    A systematic review on the effects of non-pharmacological interventions for fatigue among people with upper and/or lower limb osteoarthritis
    (Rheumatology Advances in Practice, 2024-01-01) Opeyemi Idowu
    Objectives To identify non-pharmacological fatigue interventions and determine the effectiveness of these non-pharmacological interventions in reducing fatigue immediately and over time in OA. Methods A review protocol (CRD42020163730) was developed and registered with the PROSPERO database. Included studies comprised peer-reviewed randomized controlled trials (RCTs) that examined the effects of conservative interventions on fatigue in people with upper and lower limb OA. Cochrane Collaboration’s tool for assessing the risk of bias (ROB-2) was used to assess the quality of evidence of studies. Narrative synthesis was used to summarize the effectiveness of identified fatigue interventions. Results Out of 2644 citations identified from databases, 32 reports were included after screening for titles, abstracts and full texts. Of these reports, 30 parallel RCTs, one cluster and one cross-over RCT were included. 13 RCTs were of low ROB, 6 had some concerns and 13 had high ROB. The narrative synthesis identified interventions for fatigue including exercise, activity pacing, cognitive behavioural therapy, telerehabilitation and complementary alternative therapies. Exercise interventions showed the most significant beneficial effects on fatigue. Conclusions Diverse interventions for fatigue management among individuals with upper and lower limb OA were identified. Of these, exercise interventions appear to be the most promising with the majority of these interventions favouring fatigue improvement. While cognitive behavioural therapy has limited evidence of beneficial effects, there is insufficient evidence regarding the effectiveness of other identified interventions, including complementary and alternative therapies, and telerehabilitation.

    An Analysis of Work-Related Musculoskeletal Disorders Among Butchers in Kano Metropolis, Nigeria
    (Safety at health and Work, 2016) Opeyemi Idowu
    Background: Butchering is often associated with high rates of work-related musculoskeletal disorders (WRMSDs). However, published work on the prevalence of WRMSDs among butchers in Nigeria is scarce. This is important because meat processing practices differ across geographical and cultural locations. This study was therefore aimed at analyzing WRMSDs among butchers in Kano metropolis. Methods: Sociodemographic and work-settings information was obtained from 102 male cattle butchers (age, 37.49±11.68 years) through survey. Information on the prevalence and pattern of musculoskeletal disorders was obtained from the respondents using the Standardized Nordic Questionnaire. Additional information on health seeking practices was also obtained using a pro forma. Associations between the prevalence of WRMSDs and each of the sociodemographic data and work settings were explored using Chi-square analysis. The level of significance was set at p < 0.05. Results: The 12-month and point prevalence rates of WRMSDs among butchers in this study were 88.2% and 74.5%, respectively. Whereas lower back complaints (66.7%) were the overall and lower body quadrant’s most commonly reported WRMSDs among the butchers surveyed, wrist/hand complaints were the leading upper quadrant’s (45.1%) most commonly reported WRMSDs among the respondents. There were significant associations between age and majority of WRMSDs in the body regions. Only 23.3% of the 90 individuals who had WRMSD visited the hospital to seek redress for their WRMSD. Conclusion: The prevalence of WRMSDs is high among butchers in Kano Metropolis. Few individuals with WRMSD utilize healthcare facilities. Age is a major risk factor in this setting.

    Can physical activity attenuate the impact of internet addiction on anxiety in young adults? A moderation analysis
    (Journal of Affective Disorders Reports, 2024-01) Opeyemi Idowu
    Background: The potential moderators of the nexus between internet addiction (IA) and symptoms of anxiety are less understood. This cross-sectional study aimed to assess the moderating roles of physical activity (PA) and gender in the association between IA and anxiety. Methods: A cross-sectional study of 510 Nigerian undergraduate students was carried out. IA, anxiety, and PA levels (low, moderate, and high) were assessed using Internet Addiction Test, anxiety sub-scale of Depression Anxiety Stress Scale-21, and Patient-Centered Assessment and Counseling for Exercise Plus Nutrition, respec- tively. Moderation analysis was applied while controlling for important covariates. Results: The mean age of the respondents was 21.33 ± 2.63 years. The prevalence of IA and anxiety was 57.6 % and 52.6 %. IA was positively associated with anxiety (b=0.307, 95 % CI: 0.2168-0.3982, t (498) =6.660, p < 0.001). PA level, but not gender seem to moderate the association between IA and anxiety (F (2, 498) =3.561, p=0.029, R2 change =0.011). Moreover, interaction between PA and gender indicated that the moderating effect of PA was less pronounced among females compared with males (F (3, 498) =2.895, p=0.035, R2 change =0.014). Conclusions: PA can attenuate the deleterious nexus between IA and anxiety in young adults. The attenuation of PA in IA-anxiety nexus is weaker among female young adults compared with male counterparts. PA is a viable low-cost intervention strategy in combating the effect of IA on symptoms of anxiety among young adults. Further longitudinal and experimental studies are needed to better understand the underlying mechanisms among IA, anxiety symptoms, PA, and gender.

    Clinical factors associated with bone mineral density among individuals with osteoarthritis of the hip and/or knee
    (Bulletin of Faculty of Physical Therapy, 2024-08-18) Opeyemi Idowu
    Background and objective The association of clinical factors of osteoarthritis (OA) with bone mineral density (BMD) is not well understood. We aimed to synthesize evidence regarding the associated clinical factors for low BMD in people with knee and/or hip osteoarthritis. Methods A systematic literature search limited to human studies was conducted from inception to September 12, 2022. CINAHL, Cochrane, Medline, PsycINFO, PubMed, Web of Science, and African Journal online databases were searched for all clinical factors associated with low BMD (either as osteopenia or osteoporosis). Gray literature or abstracts or protocols, studies with a mixed population of OA without a subgroup analysis for hip and or KOA and non-English were excluded. Following the title and abstract, full-text, screenings, and data extraction, data from eligible studies were synthesized based on the main objective of the study. The Joanna Brigg’s Institute (JBI) Critical Assessment tool was used for quality appraisal. Narrative synthesis and best evidence synthesis were used in the study. Result Five studies (2 case–control, 3 cross-sectional) were included after screening 3355 titles and abstracts. Clinical factors reported in the five studies included: body mass index (BMI); pain, function, and stiffness; symptom duration; presence of varus/valgus deformity; quality of life; and knee function. Whilst there was limited evidence to support the association between BMD measured at any site of the body and BMI, as well as conflicting evidence for the association of BMD with age and gender, there was insufficient evidence to support the association of BMD with other identified clinical factors of hip and or/ knee OA (p < 0.05). In addition, there is conflicting evidence for the association between BMD measured at the lumbar spine and BMI. Conclusion There is insufficient evidence on the association between BMD and its associated clinical factors. With the attendant likelihood of bias in existing studies, there is a need for well-designed studies on bone health in OA.

    Cross-cultural adaptation and psychometric evaluation of the Yoruba version of Oswestry disability index
    (PLOS ONE, 2020-01-08) Opeyemi Idowu
    Introduction Low-Back Pain (LBP) is a common public health problem that is often worsened by mal-adaptive beliefs and disability. Thus, necessitating the need for availability of outcome measures to assess these sequelae among patients with chronic LBP. This study aimed to cross-culturally adapt and determine the psychometric properties of the Yoruba version of the ODI (ODI-Y). Methods The ODI-Y was cross-culturally adapted following the process involving forward translation, synthesis, backward translation, expert review, and pilot testing. Internal consistency and test-retest reliability of the ODI-Y were determined using the Cronbach’s alpha and intra-class correlation. Other psychometric properties explored included the factor structure, convergent validity, standard error of measurement and the minimal detectable change. Results One hundred and thirty-six patients with chronic LBP took part in the validation of the ODI-Y; 86 of these individuals took part in the test-retest reliability (within 1-week interval) of the translated instrument. The mean age of the respondents was 50.5±10.6years. The ODI-Y showed a high internal consistency, with a Cronbach’s alpha (α) of 0.81. Test-retest of the Yoruba version of the ODI within 1-week interval yielded an Intra-Class Correlation coefficient of 0.89. The ODI-Y yielded a three-factor structure which accounted for 61.56% of the variance. Correlation of ODI-Y with the visual analogue scale was moderate (r = 0.30; p =0.001). The standard error of measurement and minimal detectable change of the ODI-Y were 2.0 and 5.5. Conclusions The ODI was adapted into the Yoruba language and proved to have good psychometric properties that replicated the results of other obtainable versions. We recommend it for use among Yoruba speaking patients with LBP.

    CROSS-CULTURAL ADAPTATION, RELIABILITY AND VALIDITY OF THE YORUBA VERSION OF THE ROLAND MORRIS DISABILITY QUESTIONNAIRE
    (Spine, 2017) Opeyemi Idowu
    Study design: A translation, cross-cultural adaptation, and psychometric analysis. Objective: The aim of this study was to translate, cross-culturally adapt, and validate the Yoruba version of the RMDQ. Summary of background data: The Roland-Morris Disability Questionnaire (RMDQ) is a valid outcome tool for low back pain (LBP) in clinical and research settings. There seems to be no valid and reliable version of the RMDQ in the Nigerian languages. Methods: Following the Guillemin criteria, the English version of the RMDQ was forward and back translated. Two Yoruba translated versions of the RMDQ were assessed for clarity, common language usage, and conceptual equivalence. Consequently, a harmonized Yoruba version was produced and was pilot-tested among 20 patients with nonspecific long-term LBP (NSLBP) for cognitive debriefing. The final version of the Yoruba RMDQ was tested for its construct validity and re-retest reliability among 120 and 87 patients with NSLBP, respectively. Results: Pearson product moment correlation coefficient (r) of 0.82 was obtained for reliability of the Yoruba version of the RMDQ. The test-retest reliability of the Yoruba RMDQ yielded Cronbach alpha 0.932, while the intraclass correlation (ICC) ranged between 0.896 and 0.956. The analysis of the global scores of both the English and Yoruba versions of the RMDQ yielded ICC value of between 0.995 (95% confidence interval 0.996-0.997), with the item-by-item Kappa agreement ranging between 0.824 and 1.000. The external validity of RMDQ using Quadruple Visual Analogue Scale was r = -0.596 (P = 0.001). The Yoruba version of the RMDQ had no floor/ceiling effects, as no patient achieved either of the maximum or the minimum possible scores. Conclusion: The Yoruba version of the RMDQ has excellent reliability and validity and may be an appropriate outcome tool for clinical and research purposes among Yoruba-speaking patients with LBP.

    Effect of Motivational Interviewing and Exercise on Chronic Low Back Pain: A Systematic Review and Meta‐ Analysis
    (Musculoskeletal Care, 2025) Opeyemi Idowu
    Background: The prevalence of chronic low back pain (CLBP) and its concomitant cost implications have continued to rise across the globe. Currently, there is no effective treatment for CLBP that leads to long‐term improvement. Hence, there is growing recognition of the need for behaviour techniques including motivational interviewing (MI) to address CLBP. Objective: To determine the effect of MI and exercise on pain in individuals with CLBP. Method: We searched for trials in seven databases from inception to April 2024. Trials were included if MI was used alone or in addition to an exercise programme for improving CLBP in adults aged (≥ 18 years). Results: From 3062 records retrieved, we included three randomized controlled trials (RCTs). Only one study was rated as having a low risk of bias. There is no evidence to support the benefit of MI and exercise on improving pain (SMD‐0.23, 95% CI‐ 0.55 to 0.09, I2 = 0%, p = 0.16), disability (MD‐1.80, 95% CI‐4.55 to 0.94, I2 = 85%, p = 0.20) and physical functioning (SMD 0.00, 95% CI‐1.31 to 1.32, I2 = 93%, p = 0.99). Conclusion: There is insufficient evidence to support the effect of MI and exercise on pain in individuals with CLBP. More large‐scale RCTs are needed in evaluating the effectiveness of MI and exercise in individuals with CLBP

    Efficacy of Graded Activity with and without Daily-Monitored- Walking on Pain and Back Endurance among Patients with Concomitant Low-Back Pain and Type-2 Diabetes: A Randomized Trial
    (Ethiopian Journal of Health Sciences, 2020-03-01) Opeyemi Idowu
    BACKGROUND: There is evidence supporting the efficacy of Graded Activity (GA) in managing clinical attributes of patients with Low-Back Pain (LBP) in the general population. However, it is unknown whether GA alone is efficacious in managing these clinical attributes in patients with concomitant LBP and Type-2 Diabetes (T2D) or additional daily-monitored walking will be required. METHODS: A single-blind controlled trial involving 58 patients (mean age: 48.3±9.4 years, 64.7% females) with concomitant LBP and T2D who received treatment twice weekly for twelve weeks was conducted. Participants were randomized into GA or GA with daily-monitored-walking (GAMW) groups. Pain Intensity (PI), Static Back Extensors Endurance (SBEE), Static Abdominal Muscular Endurance (SAME) and Glycaemic Control (GC) were assessed using Visual Analogue Scale, Biering-Sorensen test, flexor endurance test, and in2itTM device respectively at baseline, 4th, 8th and 12th week. Data were analysed using repeated- measures ANOVA and Unpaired t-tests at α = 0.05. RESULTS: There were significant differences in PI, SAME and SBEE among participants in each of GA and GAMW groups respectively (p<0.05). Within-group difference on GC was significant for GAMW (6.3±0.9%, 5.7±0.7%) but not GA (6.3±0.9%, 6.3±0.9%). There was significant difference (p<0.05) between GA and GAMW group participants for SBEE (7.2±0.1 sec, 7.3±0.1 sec) at week 8 of the study and GC (-0.5±0.2%, -0.6±0.5%) at the end of the study. No differences were found between GA and GAMW groups for PI and SAME. CONCLUSION: Graded activity with daily-monitored-walking produced positive effects on GC and yielded a better improvement on SAME and SBEE.

    Graded activity with and without daily- monitored-walking in patients with type 2 diabetes with low back pain: secondary analysis of a randomized-clinical trial
    (Archives of Physiotherapy, 2021-12) Opeyemi Idowu
    Background Graded activity is gradually emerging as a preferred choice in improving psychosocial outcomes including pain self-efficacy, fear-avoidance beliefs, and back-pain beliefs in the general population with low back pain (LBP). Such evidence is, however, lacking among patients with concomitant LBP and type-2 diabetes mellitus (T2DM). This secondary analysis of a randomized control trial aimed to compare the efficacy between graded activity augmented with additional daily-monitored-walking and graded activity alone on disability, pain self-efficacy (PSE), fear-avoidance beliefs (FAB), back-pain beliefs (BPB) and glycaemic control (HbA1c) in patients with concomitant LBP and T2DM. Methods Fifty-eight patients with concomitant LBP and T2DM were randomised into two groups, graded activity with daily-monitored-walking group (GAMWG = 29) or (graded activity group (GAG = 29) in this 12-week single-blind trial. Both groups received graded activity (home/work-place visits, back school and sub-maximal exercises) while the GAMWG received additional daily-monitored-walking. Disability and selected psychosocial outcomes were assessed at weeks 0, 4, 8 and 12 using Roland-Morris disability, fear-avoidance behaviour, pain self-efficacy and back belief questionnaires. Glycaemic control was assessed at weeks 0 and 12 using a point-of-care system (In2it, Biorad Latvia). Data were analysed using mean, median, Friedman’s ANOVA, Mann-Whitney test and t-tests. Results Participants’ mean age was 48.3 ± 9.4 years (95%CI: 45.6, 50.9) while 35.3% were males. The GAMWG participants (n = 25) had better outcomes (P < 0.05) than GAG participants (n = 26) on PSE (1.0, 3.0; r = − 0.1) and FAB (0.01, − 2.0; r = − 0.1) at week 4, LBP-related disability (0.01, − 2.0; r = − 0.2) at week 8 and glycaemic control at week 12 (− 0.59 ± 0.51%,-0.46 ± 0.22%). No other between-group comparisons were statistically significant. Conclusion Graded activity with daily-monitored-walking provided earlier improvements on disability, pain self-efficacy, fear-avoidance beliefs, and glycaemic control, but not back pain beliefs, in patients with concomitant LBP and T2DM.

    Perceived barriers to physical activity among Nigerian stroke survivors
    (Pan African Medical Journal, 2016-07-20) Opeyemi Idowu
    Introduction: Benefits of physical activity in the prevention and management of stroke are well documented in the literature. There is increasing evidence that stroke survivors in South-West Nigeria are physically inactive. Data on barriers to the achievement of the recommended physical activity levels including its differences along socio-demographic characteristics among stroke survivors in South-West Nigeria are needed. Methods: The Exercise Benefits and Barrier Scale and the International Physical Activity Questionnaire were administered on 121 stroke survivors to determine their perceived barriers to physical activity and physical activity levels respectively. Information on socio-demographic data and clinical variables were also collected. Results: The sample included 70.2% males, with majority of the participants reporting low physical activity levels (80.2%) and high perceived barriers (Mean=48.13, SD=7.88). The four most reported common barriers among stroke survivors were access to exercise facilities (95.0 %), being embarrassed to exercise (94.2%), economic cost demands of exercise (94.2 %) and notion that people in exercise clothes look funny (94.2%) respectively. There were no significant differences found in barriers to physical activity between gender (U= 1471.00, P= 0.74) and across each of: occupational status (H= 4.37, P=0.22), age group (H= 0.82, P= 0.84) and educational levels (H= 4.56, P= 0.33). Significant difference however existed in perceived barriers across marital status categories (H=12.87, P= 0.05). Conclusion: Stroke survivors indicated high perceived barriers to physical activity and these barriers were associated with marital status.

    Physical activity information-seeking behaviour and barriers in a sample of university undergraduate emerging adults: a cross-sectional survey
    (Bulletin of Faculty of Physical Therapy, 2024-06-19) Opeyemi Idowu
    Background Access to physical activity information provides opportunities for enduring and relevant messaging regarding physical activity. This may be a potential vehicle to optimise physical activity participation among emerging adults. This study aimed to characterise the physical activity information-seeking behaviour in a sample of university undergraduate emerging adults. Methods Five hundred and seventy-five undergraduate students (age = 21.7 ± 1.9 years) participated in the study. Respondents’ physical activity information-seeking behaviour was obtained using an adapted instrument, while physical activity and barriers were assessed using the International Physical Activity Questionnaire and the Exercise Benefits and Barrier Scale. Results Three hundred and fifty-one respondents (61%) of respondents sought physical activity information. The majority of these individuals (73.8%) sought physical activity information using social media. After identifying and controlling for confounders including engaging in physical activity programmes and faculty of study, having low physical activity levels was associated with a < 1 likelihood of seeking physical activity information compared to having high physical activity levels (odds ratio = 0.5, 95% confidence interval 0.27–0.87; p = 0.015). However, there was no association between barriers to physical activity and physical activity information-seeking behaviour (odds ratio = 1.17, 95% confidence interval 0.81–1.69; p = 0.40). Conclusion Undergraduate emerging adults seek physical activity information using social media to enhance their physical appearance and health.

    Prevalence and correlates of bullying in physiotherapy education in Nigeria
    (BMC Medical Education, 2020) Opeyemi Idowu
    Background: Bullying is an unexpressed part and parcel of medical education but it is largely unexplored in physiotherapy. This study assessed the prevalence and socio-demographic correlates of bullying in physiotherapy education in Nigeria. Methods: Two hundred and nineteen clinical physiotherapy students from three purposively selected Federal Universities in Nigeria participated in this study. Following a cross-sectional design, the Students Perception of Professor Bullying Questionnaire (SPPBQ) was used to obtain information on bullying. The SPPBQ includes a working definition of lecturer bullying followed by other sections inquiring about lecturers bullying experiences. Data was collected on socio-demographic characteristics, bullying experiences and availability of adequate policy and support on bullying. Descriptive and inferential statistics were used analyze data. Alpha level was set at p < 0.05. Results: Lifetime and point prevalence of bullying in physiotherapy education were 98.6 and 99.1%. 94.5% of the respondents had witnessed physiotherapy students bullying and there was a 100% rate of ‘no attempt’ to stop a physiotherapy lecturer from bullying. 38.4 and 44.7% of the respondents believed there was adequate school policy and support available on bullying. There was no significant association between bullying and each of age ( 2 = 0.117, p = 0.943), gender ( 2 = 0.001, p = 0.974), level of study ( 2 = 0.000, p = 0.995) and any specific university ( 2 = 1.343, p = 0.511). Conclusion: There is high lifetime and point prevalence of bullying in physiotherapy education in Nigeria, which are largely unchallenged or redressed. Being a clinical physiotherapy student ordinarily predisposes to bullying without necessary contributions of intrinsic and extrinsic factors.

    Prevalence and pattern of work-related musculoskeletal disorders among Nigerian bricklayers
    (Work, 2022) Opeyemi Idowu
    BACKGROUND: Typically, bricklayers in developing countries’ contexts manually lay bricks, concrete blocks and other similar materials to construct walls and buildings which make them susceptible to work-related musculoskeletal disorders (WRMSDs). The burden of WRMSDs among this high-risk group seems has not been well documented. OBJECTIVE: This study examined the prevalence of WRMSDs among bricklayers in Nigeria. METHODS: A cross-sectional survey of 118 consenting bricklayers from a Nigerian setting was carried out. The standardized Nordic musculoskeletal disorder questionnaire and a proforma were used to profile the prevalence of WRMSDs and socio- demographic information of the respondents. Data was analyzed using descriptive and inferential statistics. Alpha level was set at p < 0.05. RESULTS: The 12-months and 7-days prevalence of WRMSDs were 87.3% and 67.4%. Shoulder (61.0%) and the low-back (59.3%) were the two most affected anatomical sites based on 12-month prevalence. WRMSDs affecting the knees (6.8%) was the most disabling in carrying normal work routines. Working for less than 10 years was significantly associated with high prevalence of WRMSDs in the shoulder (odd ratio (OR) = 0.27, 95% confidence interval (CI) = 0.09 to 0.87) and wrist region (OR = 0.24, 95%CI 0.08 to 0.73). Having neck pain led to higher odds (OR = 0.29, 95%CI 0.13 to 0.68) of taking a break from work among the bricklayers. CONCLUSION: WRMSDs were high among Nigerian bricklayers. Years of work experience was associated with high prevalence of WRMSDs in the shoulder and wrist. In addition, taking work breaks was associated with neck pain.

    PREVALENCE OF NECK PAIN IN A RURAL COMMUNITY IN NORTHWEST NIGERIA
    (Journal of Medicine and Biomedical Research, 2015-06) Opeyemi Idowu
    Neck pain (NP) is a common health problem which exerts significant stress on physical functioning, work, productivity and health costs. However, there is a dearth of published studies on community prevalence of neck pain in rural communities in Nigeria. This study aimed at finding out the prevalence of NP among people living in Kura Local Government area in Kano State, Northwest Nigeria. Information obtained from 305 participants included socio-demographic characteristics and analysis of neck pain, using a bio data form and standardized Nordic musculoskeletal questionnaire (NMQ). The lifetime, one-year and point prevalence of neck pain in the study population were 67.9%, 65.9% and 17.0% respectively. Male gender (OR=0.325, CI=0.16-0.67), being married (OR=0.308, CI= 0.103-0.920) and being a secondary school certificate holder (OR=0.340, CI= 0.192-0.602) were important risk factors for neck pain when socio-demographic variables were adjusted for one another. Prevalence of Neck pain is high in this study population. The likelihood of having NP was higher among males, secondary school certificate holders and married individuals. Further research is warranted on ergonomic risk factors for the development of NP in these settings.

    Translation of the Fear Avoidance Beliefs Questionnaire Into Hausa Language
    (Global Journal of Health Science, 2015-11-17) Opeyemi Idowu
    Background: Self-report measures of fear-avoidance beliefs are widely used in clinical practice and research. To date there is no Hausa version of the Fear Avoidance Beliefs Questionnaire (FABQ). This is important as the Hausa language is a widely spoken language in West Africa. Objectives: The purpose of this study was to translate and validate the Hausa version of the FABQ in patients with non-specific neck pain. Methods: Two independent bilingual Hausa translators translated the English version of the FABQ into Hausa which was thereafter back translated by one independent bilingual translator. A professional expert panel revised the translations to produce a consensus version. The psychometric testing of the final translated instrument was investigated by surveying 54 Hausa speaking patients with chronic non-specific neck pain. Cross-sectional construct validity was evaluated by comparing Hausa Fear Avoidance Beliefs Questionnaire (FABQ-H) with the English version of the FABQ. Internal consistency of the FABQ-H was examined by Cronbach alpha by comparing the scores between the FABQ-H and its subscales. Test-retest reliability was evaluated by administering the Hausa version twice. Results: The translated Hausa version of FABQ proved to be acceptable. The FABQ-H showed strong correlations (r=0.94, p=0.000) with the original English version. There was also high internal consistency between the FABQ-H and its subscales (physical activity component-α=0.88, p=0.000 and work component-α=0.94, p= 0.000). The FABQ-H also showed a high test-retest reliability (intra-class correlation coefficient =0.98). Conclusion: The FABQ-H demonstrated excellent psychometric properties similar to other existing versions. The FABQ-H is recommended for clinical practice.

    Translation, cross-cultural adaptation and psychometric evaluation of yoruba version of the short-form 36 health survey
    (Health and Quality of Life Outcomes, 2015) Opeyemi Idowu
    Background and objective The Short-Form Health Survey (SF-36) is a valid quality of life tool often employed to determine the impact of medical intervention and the outcome of health care services. However, the SF-36 is culturally sensitive which necessitates its adaptation and translation into different languages. This study was conducted to cross-culturally adapt the SF-36 into Yoruba language and determine its reliability and validity. Methods Based on the International Quality of Life Assessment project guidelines, a sequence of translation, test of item-scale correlation, and validation was implemented for the translation of the Yoruba version of the SF-36. Following pilot testing, the English and the Yoruba versions of the SF-36 were administered to a random sample of 1087 apparently healthy individuals to test validity and 249 respondents completed the Yoruba SF-36 again after two weeks to test reliability. Data was analyzed using Pearson’s product moment correlation analysis, independent t-test, one-way analysis of variance, multi trait scaling analysis and Intra-Class Correlation (ICC) at p < 0.05. Results The concurrent validity scores for scales and domains ranges between 0.749 and 0.902 with the highest and lowest scores in the General Health (0.902) and Bodily Pain (0.749) scale. Scale-level descriptive result showed that all scale and domain scores had negative skewness ranging from −2.08 to −0.98. The mean scores for each scales ranges between 83.2 and 88.8. The domain scores for Physical Health Component and Mental Health Component were 85.6 ± 13.7 and 85.9 ± 15.4 respectively. The convergent validity was satisfactory, ranging from 0.421 to 0.907. Discriminant validity was also satisfactory except for item ‘1’. The ICC for the test-retest reliability of the Yoruba SF-36 ranges between 0.636 and 0.843 for scales; and 0.783 and 0.851 for domains. Conclusion The data quality, concurrent and discriminant validity, reliability and internal consistency of the Yoruba version of the SF-36 are adequate and it is recommended for measuring health-related quality of life among Yoruba population. The data quality, concurrent and discriminant validity, reliability and internal consistency of the Yoruba version of the SF-36 are adequate and it is recommended for measuring health-related quality of life among Yoruba population.

    Validation of the Yoruba Version of the Pain Self-Efficacy Questionnaire in Patients with Chronic Low Back Pain
    (Spine, 2021) Opeyemi Idowu
    Study Design. Cultural adaptation and psychometric analysis. Objective. This study determined the test–retest reliability, acceptability, internal consistency, divergent validity of the Yoruba pain self-efficacy questionnaire (PSEQ-Y). It also examined the ceiling and floor effects and the small detectable change (SDC) of the PSEQ-Y among patients with chronic low back pain (LBP). Summary of Background Data. There are various indigenous language translations of the PSEQ and none adapted to African language. However, translations of the PSEQ into Nigerian languages are not readily available. Methods. The validity testing phase of the study involved 131 patients with LBP, while 83 patients with LBP took part in the reliability phase. Following the Beaton recommendation for cultural adaptation of instruments, the PSEQ was adapted into the Yoruba language. The psychometric properties of the PSEQ-Y determined comprised: internal consistency, divergent validity, test–retest reliability, and SDC. Results. The mean age of the participants was 52.96±17.3 years. The PSEQ-Y did not correlate with the Yoruba version of Visual Analogue Scale (VAS-Y) scores (r ¼ –0.05; P ¼ 0.59). The values for the internal consistency and the test–retest reliability of the PSEQ-Y were 0.79 and 0.86, with the 95% confidence interval of the test–retest reliability ranging between 0.82 and 0.90. The standard error of measurement (SEM) and the SDC of the PSEQ-Y were 1.2 and 3.3, respectively. The PSEQ-Y had no floor or ceiling effect, as none of the respondents scored either the minimal or maximal scores. Conclusion. This is the first study in Nigeria to culturally adapt PSEQ. The PSEQ-Y showed adequate psychometric properties similar to existing versions. Therefore, the tool can be used to assess pain self-efficacy in clinical and research settings and help to improve the health outcomes of patients chronic LBP.
