Cross-Cultural Adaptation of the Profile Fitness Mapping Neck Questionnaire to Brazilian Portuguese: Internal Consistency, Reliability, and Construct and Structural Validity

Cross-cultural adaptation, reliability and validity tests of the Chinese version of the Profile Fitness Mapping neck questionnaire

OBJECTIVE

To translate and culturally adapt the Profile Fitness Mapping neck questionnaire (ProFitMap-neck) into the Chinese version and evaluate its psychometric properties.

METHODS

The procedure of translation and cross-cultural adaptation was performed according to the recommended guidelines. A total of 220 patients with chronic neck pain (CNP) and 100 individuals without neck pain participated in the study. Internal consistency, test-retest reliability, content validity and construct validity were investigated.

RESULTS

The Chinese version of ProFitMap-neck (CHN-ProFitMap-neck) showed adequate internal consistency (Cronbach's α = 0.88-0.95). A good test-retest reliability was proven by the intraclass correlation coefficient (ICC_3A,1 = 0.78-0.86). Floor-ceiling effects were absent. Exploratory factor analysis revealed 6 factors for the symptom scale and 4 factors for the function scale. The CHN-ProFitMap-neck showed a moderate to high negative correlation with NDI (r = 0.46-0.60, P < 0.01), a small to moderate negative correlation with VAS (r = 0.29-0.36, P < 0.01), and a small to high positive correlation with SF-36 (r = 0.21-0.52, P < 0.01). No significant correlation between the CHN-ProFitMap-neck function scale and VAS (P > 0.05) or the mental health domain of the SF-36 was found (P > 0.05). The CHN-ProFitMap-neck scores were significantly lower in the CNP group than in the non-CNP group (P < 0.01).

CONCLUSIONS

The CHN-ProFitMap-neck had acceptable psychometric properties and could be used as a reliable and valid instrument in the assessment of patients with chronic neck pain in mainland China.

Translation and cross-cultural adaptation of the risk assessment instrument TilThermometer for a Swedish version – patient handling in the healthcare sector

Background

Work-related musculoskeletal disorders are common in the healthcare sector due to exposure of physical demanding work tasks. Risk assessment is necessary to prevent injuries and promote a safety culture. The TilThermometer has proved to be useful in the Netherlands for assessing healthcare workers’ physical exposure to patient handling. The aim of this study was to translate the risk assessment instrument TilThermometer from Dutch to Swedish, perform cross-cultural adaptation, and evaluate its linguistic validity to a Swedish healthcare context.

Methods

Translation and validation process was performed according to following eight steps: 1) Translation (two translators), 2) Synthesis, 3) Back-translation (two back-translators), 4) Synthesis, 5) Linguistic review (one bilingual reviewer), 6) fifteen experts in a panel review according to Delphi-method, 7) Semi-structured interviewing eleven informants, analyzed using qualitative content analysis and step 8) discussion and input from creators of the instrument.

Results

A new Swedish version, the TilThermometer, was provided through the translation process (steps 1–5). The linguistic validity and usefulness were confirmed thru step 6 and 7. Consensus was reached in the expert review after two rounds, comments were analyzed and grouped into five groups. The qualitative content analyses of the interviews emerged in to three categories: 1) “User-friendly and understandable instrument”, 2) “Further development”, and 3) “Important part of the systematic work-environment management”.

Conclusion

In this study, the cross-cultural adaption and translation performed of the Swedish version of TilThermometer assured linguistic validity. This is this first phase before further testing the psychometrics aspects, inter-rater reliability and feasibility of TilThermometer. In the second phase TilThermometer will be implemented and evaluated together with other measures in the Swedish healthcare sector.

DESIGN

Cross-sectional study.

SETTINGS

University healthcare facility and online.

PARTICIPANTS

People with chronic neck pain (n = 178).

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

Participants answered the translated version of Northwick Park Neck Pain Questionnaire, the Neck Disability Index, the Numerical Rating Scale for pain, the Tampa Scale for Kinesiophobia and the Pain Catastrophizing Scale. Seven to ten days after that, a subset of 84 participants answered the Northwick Park Neck Pain Questionnaire again. The structural (exploratory and confirmatory factor analyses) and construct validities, internal consistency, reliability and concordance were assessed. Level of significance was set at 5%.

RESULTS

Participants' (35.6 ± 13.5 years old) with symptoms duration of 54.4 ± 60.4 months scored 25.5 ± 14.0 on the Brazilian Northwick Park Neck Pain Questionnaire and 11.9 ± 5.8 on the Neck Disability Index. The structural analysis showed that the short version of the Northwick Park Neck Pain Questionnaire has an adequate structure to measure disability due to neck pain. Correlations with other questionnaires were between 0.268 and 0.678, Cronbach's alfa was 0.76, intraclass correlation coefficient was 0.96, standard error of measurement was 2.74 and minimal detectable change was 7.60.

CONCLUSION

The short version of the Northwick Park Neck Pain Questionnaire is valid and reliable to be used in patients with chronic neck pain, as it presented adequate measurement properties of structural and construct validity, reliability and concordance.

Measurement properties of the Brazilian version of the Copenhagen Neck Functional Disability Scale in patients with chronic neck pain

OBJECTIVE

To evaluate the measurement properties of the Brazilian version of the Copenhagen Neck Functional Disability Scale (CNFDS) in patients with chronic neck pain.

METHODS

One hundred and five patients were included in the study. The structural validity of the CNFDS was assessed by exploratory and confirmatory factor analysis with the following fit indices: chi-square divided by degrees of freedom (chi-square/df), root mean square error of approximation (RMSEA), comparative fit index (CFI), and Tucker-Lewis index (TLI). To test the construct validity, the CNFDS score was correlated with the Numerical Pain Rating Scale, the Tampa Scale of Kinesiophobia, the Pain-Related Catastrophizing Thoughts Scale, and Neck Disability Index (NDI). A subsample of 43 patients filled the CNFDS at two different times, and test-retest reliability was measured using the intraclass correlation coefficient (ICC), standard error of measurement (SEM), and minimum detectable change (MDC). The internal consistency of the CNFDS was analyzed by Cronbach's alpha.

RESULTS

CNFDS presented a unidimensional structure, with goodness of fit indices: chi-square/df = 1.37, CFI = 0.94, TLI = 0.93, RMSEA = 0.059. The CNFDS showed satisfactory results of reliability (ICC = 0.93) and internal consistency (Cronbach's alpha = 0.84). The SEM was 1.72 and the MDC was 4.76. The CNFDS showed a high correlation with the NDI (rho = 0.718) and a low correlation with the other instruments. There were no floor and ceiling effects.

CONCLUSION

The Brazilian version of the CNFDS with a one-dimensional structure and 15 items has adequate measurement properties.

Brazilian version of the Neck Bournemouth Questionnaire does not have a well-defined internal structure in patients with chronic neck pain

OBJECTIVE

To investigate the structural validity of the Brazilian version of the Neck Bournemouth Questionnaire in patients with chronic neck pain.

DESIGN

Cross-sectional study.

SETTING

Community participants collected via online platform.

SUBJECTS

Participants with neck pain (minimal pain intensity of 3 points at rest on 11-point Numerical Rating Scale), both genders and aged ⩾18 years old.

MAIN MEASURE

The Numerical Rating Scale, Neck Disability Index, Pain-Related Catastrophizing Thoughts Scale, Tampa Scale of Kinesiophobia and the Neck Bournemouth Questionnaire were completed. Exploratory and confirmatory factor analyses were used to identify dimensionality and to compare different structures of the Neck Bournemouth Questionnaire.

RESULTS

We included 103 participants. The sample consisted mostly of adults (mean age = 33.64 years, standard deviation = 10.48 years), females (n = 82, 79.6%), lean, single and with higher education. The exploratory factor analysis with implementation of the parallel analysis identified the one-dimensional structure of the Neck Bournemouth Questionnaire, with a Kaiser-Meyer-Olkin value of 0.80 and Bartlett's test significant (P < 0.05). We observed that all structures tested in this study presented a high amount of residues in confirmatory factor analysis, which were identified by the value of root mean square error of approximation > 0.08 and chi-square/degree of freedom > 3.00.

CONCLUSION

The internal structure of the Brazilian version of the Neck Bournemouth Questionnaire is not clear and well-defined. It was not possible to identify the construct measured by the instrument in individuals with chronic neck pain.

The ProFitMap-neck - a questionnaire for measuring symptoms and functional limitations in neck pain: reliability, validity and cross-cultural adaptation of the Turkish version

Background/aim

The Profile Fitness Mapping neck questionnaire (ProFitMap-neck) is a reliable and valid assessment instrument for measuring neck-related symptoms and functional limitations in people with neck pain, but a Turkish version of it had not been published. The purpose of this study was to investigate the adaptation, validity, and intrarater reliability of the Turkish version of the ProFitMap-neck.

Materials and methods

Two hundred and thirty-five individuals with chronic neck pain were enrolled in the study. Intrarater reliability was assessed by intraclass correlation coefficient (ICC) and Cronbach’s alpha was calculated for internal consistency. For concurrent validity, ProFitMap-neck scores were compared with neck disability index (NDI) and visual analoguepain scale (VAS) scores using Pearson’s correlation coefficient analysis. The ProFitMap-neck, NDI, VAS, and short form health survey (SF-36) were administered to all participants.

Results

For intrarater analysis, ICC ranged between 0.72 and 0.84. The total score was 0.83, indicating excellent reliability. The correlation of the ProFitMap-neck with NDI and VAS was 0.71 and 0.68, respectively, indicating good concurrent validity.

Conclusion

The ProFitMap-neck is an evaluation instrument with sufficient validity and reliability to be used for evaluating Turkish patients with neck pain. Use of this scale can reveal how, how often, and how much these patients’ pain affects their symptoms and functional activities.
