Ontology highlight
ABSTRACT: Objective
The objective of the present study was to develop a questionnaire to measure the consequences of neck, midback and low back pain, relevant for schoolchildren aged 9-12 years.Design
The development of the questionnaire was carried out in three phases: (1) generation of items, (2) pilot testing and (3) conceptualisation.Setting
Danish primary schools.Participants
Children aged 9-12 years from a local school were invited for completion of questionnaires and subsequent interviews.Methods
In phase 1 an extensive literature search identified items from existing questionnaires measuring musculoskeletal disability in children. These were added to items from a previously conducted qualitative study and constituted the basis for the new questionnaire. In phase 2 two consecutive pilot tests were performed to test for comprehension and feasibility of the questionnaire. Phase 3 consisted of a categorisation of the newly developed items according to the WHO's International Classification of Functioning, Disability and Health (ICF).Results
The combination of the previously conducted qualitative study and the literature review resulted in an item pool of 35 items. Through the process of item formulation and pilot testing, these were reduced to 28 items in the final questionnaire, which represented all categories in the ICF model. The qualitative study identified codes giving relative weight to four important domains. These were not included in any of the existing questionnaires but were added to the new questionnaire.Conclusions
We developed the first version of a questionnaire to measure the consequences of back or neck pain in children. The process showed the importance of combining research methods, each adding important contributions to the final product. Subsequent work will finalise the questionnaire, allowing various options for use of the questionnaire.

Project description:ObjectiveThe objective of this study was to finalise the development of the Young Disability Questionnaire (YDQ-spine) to measure the consequences of neck, midback and low back pain, relevant for schoolchildren aged 9-12 years.DesignA cross-sectional field test of the YDQ-spine was carried out.SettingDanish primary schools.ParticipantsChildren aged 9-12 years from all Danish schools were invited to complete the questionnaire.MethodsEight hundred and seventy-three schools were invited to participate. Consenting schools received information material, instructions and a link to an electronic version of the prefinal YDQ-spine. Local teachers distributed the electronic YDQ-spine to children aged 9-12 years. Descriptive statistics and item characteristics were carried out. Item reduction was performed using partial interitem correlations (scrutinising correlations>0.3) and factor analyses (items loading>0.3 were retained) to eliminate redundant items and to obtain insight into the structure of the questionnaire.ResultsA total of 768 children from 20 schools answered of the questionnaire and 280 fulfilled the inclusion criteria of having back and/or neck pain (36%). Multisite pain was reported by 38%. Partial interitem correlations and factor analyses resulted in elimination of four items which were considered redundant leaving 24 items in the final YDQ-spine with an optional section on what matters most to the child. The factor analyses showed a two-factor structure with a physical component (13 items) and a psychosocial component (10 items) in addition to one standalone item (sleep).ConclusionThe YDQ-spine is a novel questionnaire with satisfactory content validity measuring physical and psychosocial components (including sleep disturbances) of spinal pain in children aged 9-12 years. It also offers an optional section on what matters most to the child allowing targeted care in clinical practice.

Project description:BackgroundReducing the number of items in a questionnaire while maintaining relevant information is important as it is associated with advantages such as higher respondent engagement and reduced response error. However, in health care, after the original design, an a posteriori check of the included items in a questionnaire is often overlooked or considered to be of minor importance. When conducted, this is often based on a single selected method. We argue that before finalizing any lifestyle questionnaire, a posteriori validation should always be conducted using multiple approaches to ensure the robustness of the results.ObjectiveThe objectives of this study are to compare the results of two statistical methods for item reduction (variance inflation factor [VIF] and factor analysis [FA]) in a lifestyle questionnaire constructed by combining items from different sources and analyze the different results obtained from the 2 methods and the conclusions that can be made about the original items.MethodsData were collected from 79 participants (heterogeneous in age and sex) with a high risk of metabolic syndrome working in a financial company based in Tokyo. The lifestyle questionnaire was constructed by combining items (asked with daily, weekly, and monthly frequency) from multiple validated questionnaires and other selected questions. Item reduction was conducted using VIF and exploratory FA. Adequacy tests were used to check the data distribution and sampling adequacy.ResultsAmong the daily and weekly questions, both VIF and FA identified redundancies in sleep-related items. Among the monthly questions, both approaches identified redundancies in stress-related items. However, the number of items suggested for reduction often differed: VIF suggested larger reductions than FA for daily questions but fewer reductions for weekly questions. Adequacy tests always confirmed that the structural detection was adequate for the considered items.ConclusionsAs expected, our analyses showed that VIF and FA produced both similar and different findings, suggesting that questionnaire designers should consider using multiple methods for item reduction. Our findings using both methods indicate that many questions, especially those related to sleep, are redundant, indicating that the considered lifestyle questionnaire can be shortened.

Project description:STUDY OBJECTIVE:To develop a measure of unplanned pregnancy that is valid, reliable, and appropriate in the context of contemporary demographic trends and social mores and can be used in a variety of situations, including the production of population prevalence estimates. DESIGN:A two stage study design: qualitative (inductive) methods to delineate the construct of pregnancy planning, and quantitative/psychometric methods to establish the means of measurement. SETTING:Eight health service providers (comprising 14 clinics, including antenatal, abortion, and one general practitioner) across London, Edinburgh, Hertfordshire, Salisbury, and Southampton in the UK. PARTICIPANTS:Samples comprised a mixture of pregnant (continuing pregnancy and opting for abortion) and recently pregnant (post-abortion and postnatal) women. At the qualitative stage, 47 women took part in depth interviews (20 of whom were re-interviewed after the birth of their baby). Items were pre-tested with 26 women, and two psychometric field tests were carried out with, respectively, 390 and 651 women. MAIN RESULTS:A six item measure of unplanned pregnancy was produced. Psychometric testing demonstrated the measure's high reliability (Cronbach's alpha = 0.92; test-retest reliability = 0.97) and high face, content, and construct validity. Women's positions in relation to pregnancy planning are represented by the range of scores (0-12). CONCLUSIONS:A psychometric measure of unplanned pregnancy, the development of which was informed by lay views, is now available. The measure is suitable for use with any pregnancy regardless of outcome (that is, birth, abortion, miscarriage) and is highly acceptable to women.

Project description:Common mental disorders (CMD) are among the most significant contributors to disability worldwide. Patient-reported disability outcomes should be included as a key metric in the comparative assessment of value across global mental health interventions. This study aims to evaluate the validity of a widely used, cross-cultural tool - the 12-item World Health Organization Disability Assessment Schedule II (WHODAS) - as a functional outcome measure for CMD treatment.The study population includes 1024 participants with CMD enrolled in the MANAS trial in India. CMD was assessed using the Revised Clinical Interview Schedule (CIS-R). Disability was assessed using the 12-item WHODAS II plus a measure of disability days. This analysis presents the correlations between these disability items and CMD symptom severity at 2 months after enrollment (convergent validity) and the items' associations with CMD recovery 4 months later (external responsiveness).All items showed a positive correlation of disability with CMD symptom severity (p < 0.001). The WHODAS items of 'standing,' 'household responsibilities,' and 'emotional disturbance' explained the most variance in CMD symptom severity. Improvements in 'disability days,' 'emotional disturbance,' 'standing,' 'household responsibilities,' 'day-to-day work,' and 'concentrating' were significantly associated with CMD recovery over follow-up.Further research is recommended on a CMD-specific WHODAS subscale comprised of the six WHODAS items found to be most strongly associated with CMD severity and recovery. This shorter, CMD-specific disability subscale would critically serve as a common metric to compare intervention impact on patient-centered outcomes and, in turn, to allocate global mental health resources efficiently.

Project description:BackgroundCountry by country similarities and differences in physical therapy practice exists. Therefore, before updates in practice can be provided, such as trainings in evidence-based practice, it is necessary to identify the profile and nature of practice in a given country or setting. Following a search of the international literature, no appropriate tool was identified to collect and establish data to create the profile of physical therapy practice in the Philippines. We therefore developed, validated and pilot tested a survey instrument which would comprehensively describe the practice of physical therapy in the PhilippinesFindingsWe used a mixed methods design to answer our study aims. A focus group interview was conducted among a group of physical therapists to establish the content and contexts of items to be included in the survey instrument. Findings were amalgamated with the information from the literature on developing survey instruments/questionnaires. A survey instrument was drafted and named as the Physical Therapy Profile Questionnaire (PTPQ). The PTPQ was then validated and pilot tested to a different group of physical therapists.The final version consisted of five separate parts namely (A) General information and demographics, (B) Practice Profile, (C) Treatment Preferences, (D) Bases for clinical work and (E) Bases for educational/research work. At present the PTPQ is relevant to the Philippines and could be used by any country which has a similar nature of practice with the Philippines.ConclusionThe Physical Therapy Practice Questionnaire (PTPQ) was shown to have good face and content validity among the Filipino physical therapists and their context of practice. It has also been found to be useful, easy to administer tool and in a format appealing to respondents. The PTPQ is expected to assist comprehensive data collection to create a profile of physical therapy practice in the Philippines.

Project description:BackgroundTreatment- and work-related aspects have been neglected in health-related quality of life (HRQOL) measures in multiple sclerosis (MS). We aimed to develop a brief instrument covering all important impairment-, activity-, participation-, and treatment-related aspects for use in research and practice.MethodsThe 27-item Multiple Sclerosis Quality of Life Questionnaire (MS-QLQ27) was developed using open item collection, a multidisciplinary expert panel, and cognitive pretesting. It was evaluated for reliability, construct validity, and responsiveness in 100 patients presenting with relapse (84 at follow-up ~14 days later). Construct validity was analyzed by correlating the MS-QLQ27 with the disease-specific Hamburg Quality of Life Questionnaire in MS (HAQUAMS) and generic HRQOL instruments. The Expanded Disability Status Scale (EDSS) was used to analyze known-groups validity. Responsiveness was determined as the correlation of changes in MS-QLQ27 scores with changes in validation criteria.ResultsInternal consistency was high (Cronbach α = 0.94 at baseline and 0.93 at follow-up). Convergent validity was supported by direction and magnitude of associations with disease-specific and generic instruments. Correlations with change in convergent criteria were strong, indicating responsiveness. The HAQUAMS showed the strongest associations with the MS-QLQ27. The MS-QLQ27 showed the highest effect size compared with other patient-reported outcomes and the EDSS. It successfully distinguished between levels of disease severity.ConclusionsThese results indicate that the MS-QLQ27 is a reliable, valid, and highly responsive instrument for assessing HRQOL during relapse evolution in MS. Its advantages are that it is brief yet comprehensive, covering work- and treatment-related aspects not addressed in previous measures.

Project description:The aim of this study is to evaluate the item-level psychometrics of the Ascertain Dementia Eight-Item Informant Questionnaire (AD-8) by examining its dimensionality, rating scale integrity, item fit statistics, item difficulty hierarchy, item-person match, and precision. We used confirmatory factor analysis and the Rasch rating scale model for analyzing the data extracted from the proxy versions of the 2019 and 2020 National Health and Aging Trends Study, USA. A total of 403 participants were included in the analysis. The confirmatory factor analysis with a 1-factor model using the robust weighted least squares (WLSMV) estimator indicated a unidimensional measurement structure (χ2 = 41.015, df = 20, p = 0.004; root mean square error of approximation = 0.051; comparative fit index = 0.995; Tucker-Lewis Index = 0.993;). The findings indicated that the AD-8 has no misfitting items and no differential item functioning across sex and gender. The items were evenly distributed in the item difficulty rating (range: -2.30 to 0.98 logits). While there were floor effects, the AD-8 revealed good reliability (Rasch person reliability = 0.67, Cronbach's alpha = 0.89). The Rasch analysis reveals that the AD-8 has excellent psychometric properties that can be used as a screening assessment tool in clinical settings allowing clinicians to measure dementia both quickly and efficiently. To summarize, the AD-8 could be a useful primary screening tool to be used with additional diagnostic testing, if the patient is accompanied by a reliable informant.

Project description:BackgroundBack pain in children is common and early onset of back pain has been shown to increase the risk of back pain significantly in adulthood. Consequently, preventive efforts must be targeted the young population but research relating to spinal problems in this age group is scarce. Focus has primarily been on the working age population, and therefore specific questionnaires to measure spinal pain and its consequences, specifically aimed at children and adolescents are absent. The purpose of this study was to develop a questionnaire for schoolchildren filling this gap.MethodsThe Young Spine Questionnaire (YSQ) was developed in three phases--a conceptualisation, development and testing phase. The conceptualisation phase followed the Wilson and Cleary model and included questions regarding spinal prevalence estimates, pain frequency and intensity, activity restrictions, care seeking behaviour and influence of parental back trouble. Items from existing questionnaires and the "Revised Faces Pain Scale" (rFPS) were included during the development phase. The testing phase consisted of a mixed quantitative and qualitative iterative method carried out in two pilot tests using 4th grade children and focusing on assessment of spinal area location and item validity.ResultsThe testing phase resulted in omission of the pain drawings and the questions and answer categories were simplified in several questions. Agreement between the questionnaire prevalence estimates and the interviews ranged between 83.7% (cervical pain today) and 97.9% (thoracic pain today). To improve the understanding of the spinal boundaries we added bony landmarks to the spinal drawings after pilot test I. This resulted in an improved sense of spinal boundary location in pilot test II. Correlations between the rFPS and the interview pain score ranged between 0.67 (cervical spine) and 0.79 (lumbar spine).ConclusionsThe Young Spine Questionnaire contains questions that assess spinal pain and its consequences. The items have been tested for content understanding and agreement between questionnaire scores and interview findings among target respondents. These preliminary results suggest that the YSQ is feasible, has content validity and is a well understood questionnaire to be used in studies of children aged 9 to 11 years.

Project description:BackgroundMany chiropractors use spinal manipulative techniques (SMT) to treat spinal pain. A recent Delphi study posited 18 items across five domains as predictors of patients experiencing non-specific low back pain most likely to experience a strong and immediate positive response to SMT. We sought to create a 'pen and paper' questionnaire that would measure these items and then pilot its use in a clinical setting to determine its 'usability' for a larger study. Knowing this information would inform a more efficacious use of SMT.MethodOf the 18 items identified in the Delphi study, 13 were deemed historical in nature and readily provided by the chiropractor and patient. A literature search revealed reliable and valid measures for two more items. The remaining three items were generated by creating descriptive questions matched to an appropriate Likert scale. A panel of six chiropractors who had used SMT for at least 7 years when treating non-specific low back pain was formed to evaluate the items for clarity and relevance. Ten Western Australian chiropractors were then recruited to pilot the questionnaire on ten consecutive patients with non-specific low back pain where SMT was used from March to June 2020. Ethics approval was obtained from Murdoch University.ResultsCOVID-19 restrictions impacted on practitioner recruitment and delayed the data collection. Of the intended 100 participants, only 63 could be recruited over a 3-month period from seven chiropractors. Time constraints forced the closure of the data collection. The measures of all predictor items demonstrated ceiling effects. Feedback from open-ended practitioner questions was minimal, suggesting an ease of use.ConclusionThe length of time and level of participation required to collect the calculated sample size was inadequate and suggested that incentivization may be required for a larger investigation. Significant ceiling effects were found and suggested that participants did so because of a positive bias toward chiropractic care and the use of SMT. The questionnaires in this pilot study require alternative measures and further validation before use in a larger study.

Project description:There are limited tools to measure the burden of disease and effectiveness of medical/surgical interventions in patients with cryptoglandular fistulas. The aim of this study was to explore concepts that are relevant and important to patients with complex cryptoglandular fistulas (CCF) and to develop a patient-centred, disease-specific, patient-reported outcome measure (PROM) to assess symptom burden and impacts of CCF. A targeted literature review was conducted, followed by one-to-one telephone interviews with five colorectal surgeons (USA, n = 3; UK, n = 1; Spain, n = 1) and 20 US adult patients with CCF to inform the development of a conceptual model and a CCF-specific PROM. The targeted literature review informed the development of the preliminary conceptual model and identified a PROM in the literature that was used as a reference to generate the draft CCF-specific PROM. The colorectal surgeon interviews provided insights on the experience of patients with CCF to refine the conceptual model, formulate probing questions for use in patient interviews, and to develop the draft CCF-specific PROM. Patients' descriptions of their experiences with symptoms and the impacts on their lives and evaluation of the draft CCF-specific PROM in concept elicitation and cognitive interviews were used to develop the final conceptual model and final CCF-specific PROM. Ten symptoms (odour, pain during bowel movement, abscess, post-operative pain, discharge/drainage/leakage, anal/perianal pain, inflammation/swelling, skin irritation, bleeding and itchiness) and 11 impacts (discomfort, inability to exercise, embarrassment, difficulty sitting, worry about disease, adapted life to maintain hygiene, negatively impacted social life/isolation, inability to perform daily activities, reduced interest in sex, negatively impacted intimate relationships and negatively impacted mood) were reported as most salient by patients. The patient experience, clinician perspective, and literature review provided input to item generation. Evaluation of relevance and patient understanding through cognitive interviews with patients provided evidence for the content validity of the new patient-reported outcome measure: the 20-item Complex Cryptoglandular Fistula Questionnaire™ (CCFQ-20™). The CCFQ-20™ is a new clinician-guided, patient-validated, disease-specific patient-reported outcome measure that measures disease impact and quality of life in patients with CCF.
