A case for the use of Q-methodology in disability research: lessons learned from a training workshop.

Purpose. Q-methodology was developed to analyse subjective responses to a range of items dealing with specific topics. This article describes the use of Q-methodology and presents the results of a Q-study on perspectives on disability carried out in a training workshop as evidence for its usefulness in disability research. Method. A Q-sort was administered in the context of a training workshop on Q-method. The Q-sort consisted of statements related to the topic of disability. The responses were analysed using specifically developed software to identify factors that represent patterns of responses. Results. Twenty-two of the 23 respondents loaded on four factors. These factors appeared to represent different paradigms relating to the social, medical and disability rights models of disability. The fourth factor appeared to be that of a family perspective. These are all models evident in the disability research literature and provide evidence for the validity of Q-method in disability research. Conclusion. Based on this opportunistic study, it would appear that Q-methodology is a useful tool for identifying different view points related to disability.

Content validity and test-retest reliability of a low back pain questionnaire in Zimbabwean adolescents

BackgroundIn Zimbabwe, a recent increase in the volume of research on recurrent non-specific low back pain (NSLBP) has revealed that adolescents are commonly affected. This is alarming to health professionals and parents and calls for serious primary preventative strategies to be developed and implemented forthwith. Early identification initiatives should be prioritised in order to curtail the condition and its progression. In an attempt to be proactive in minimising the prevalence of recurrent NSLBP, this study was conducted to evaluate the content validity and test-retest reliability of a survey questionnaire with the aim of proffering a valid and reliable questionnaire which can be used in non-clinical settings to identify adolescents with recurrent NSLBP in Harare, Zimbabwe and determine the possible factors associated with the condition.MethodsThe study was conducted in two parts. The first part assessed content validity of the questionnaire using four experts derived from academia and clinical practice. The second part evaluated the reliability of the questionnaire among 125 high school-children aged between 13 and 19 years in a test-retest study.ResultsTwenty-six (26) out of thirty questions in the questionnaire had an Item Content Validity index of 1.00, demonstrating complete agreement among content experts. Overall, the Scale Content Validity Index for the questionnaire was 0.97. Item completion for the reliability study was satisfactory. The questionnaire items had kappa values ranging from 0.17 (slight agreement) to 1 (perfect agreement). High levels of reliability were found for the questions on school bag use (k=0.94), sports participation (k=0.97), and lifetime prevalence (k=0.89).ConclusionExcellent content validity and slight to perfect test-retest reliability was found for the Low Back Pain (LBP) questionnaire. These results are comparable to findings of other studies evaluating the psychometric properties of LBP questionnaires. Cognisant of the limitations of the study, the results of this study suggest that the LBP questionnaire could be used in local studies investigating LBP among adolescents although questions enquiring on functional limitations and sciatica may need further consideration.

Profile of Rugby Injuries in High School Zimbabwean Adolescents

Background: Rugby is a popular sport played in many countries worldwide. There has been recent growing interest for the sport in Zimbabwe especially among adolescents. However, no study has been done to documentthe profile of rugby-related injuries among Zimbabwean adolescents between the ages of 10 and 19 years. The goal of the present study is to describe the injuries sustained by adolescent males during the 2014 high school rugby season. Methods: A cross-sectional survey was conducted involving 275 male adolescents’ rugby players who competed in the Super Eight School Rugby League in Harare, Zimbabwe. Results: The mean age of the sample was 16 years (SD = 1.4). 58.2% of participants sustained at least one rugby-related injury. There were 561 injuries reported in total, of which 63.3% (n = 355) were new injuries and the remainder were recurrent cases. 7.7% (n = 43) of the injuries were graded as severe with participants missing rugby activities for more than 28 days. Of the 561 injuries that occurred, 59.4% (n = 333) occurred during competitive matches in the second half (59.5%). Injuries due to tackles were the most frequent accounting for 48.3% (n = 271) of all injuries sustained. The lower limbs were the most frequent body region affected (38.6%, n = 217). When comparing position of play, flankers sustained the most injuries (14.1%) and there were no differences in incidence of injury between forward and backline players. Conclusion: Our findings on the profile of rugby injuries among male Zimbabwean adolescents were similar to those of other studies in certain aspects but differed in others. Most injuries occurred in competition during the second half of the game mainly from tackles. Both junior and senior players were equally affected. The lower limbs were frequently injured especially the knee region.

Physiotherapists’ knowledge of pain: A cross-sectional correlational study of members of the South African Sports and Orthopaedic Manipulative Special Interest Groups

Background . Pain is the most common complaint for which patients seek the help of a physiotherapist. Furthermore, pain has been identified as the fifth vital sign, indicating the attention with which physiotherapists should be assessing pain. Previous studies have found deficits in pain knowledge among healthcare providers. Poor knowledge about pain is recognised to lead to poor assessment ability, and subsequently, to poor pain management. Objective . To investigate the pain knowledge of sports and orthopaedic manipulative physiotherapists in South Africa (SA). Methods . Data were collected online by means of a demographic questionnaire and Unruh’s Revised Pain Knowledge and Attitudes Questionnaire (RPKAQ). Participants were members of the Sports Physiotherapy Group and Orthopaedic Manipulative Physiotherapy Group of the South African Society of Physiotherapy. Results . The mean score for the RPKAQ was 65.5% (standard deviation (SD) ±8.6). Only 14.45% of the physiotherapists scored ≥75%. Lowest scores were obtained for the ‘assessment and measurement of pain’ (47.6%; SD ±15.6) and ‘developmental changes in pain perception’ (58.7%; SD ±20.8) sections of the RPKAQ, while the highest mean score was obtained for the ‘physiological basis of pain’ section (76.8%; SD±14.6). Gender, ethnicity (defined by home language), academic training and clinical experience did not contribute significantly to overall pain knowledge. Conclusion. There is an inadequate level of pain knowledge among members of the sports and orthopaedic manipulative physiotherapy groups in SA, particularly in the areas of the assessment and measurement of pain, and developmental changes in pain perception.
