Cross-cultural translation,validity, and reliability of the French version of the Neurophysiology of Pain Questionnaire

Pain physiology education is an important component in the management of patients with chronic musculoskeletal pain. The Neurophysiology of Pain Questionnaire (NPQ) was developed in English to assess pain physiology knowledge in patients. This study aimed to translate the NPQ into French (NPQ-Fr) and to investigate the main psychometric properties of the NPQ-Fr. The translation was performed using the best practice translation guidelines. One hundred and one French-speaking patients with chronic non-specific spinal pain completed the NPQ-Fr to assess its acceptability and presence of floor/ceiling effects and test its dimensionality. The construct validity was tested by comparing the patients’ NPQ-Fr scores to those of 17 physiotherapists and investigating its correlation with subscales of the Short Form-36 questionnaire. The reliability (i.e., internal consistency and test-retest reliability) was also investigated. To test the test-retest reliability, 70 patients were asked to complete the NPQ-Fr twice with one week in between. Regarding the NPQ-Fr psychometric properties: 1) acceptability was good; 2) internal consistency reached a Cronbach α-coefficient of 0.44; 3) no floor and ceiling effects were observed in patients; 4) a principal factor analysis generated three major factors; 5) construct validity was good; and 6) reliability was acceptable (intraclass correlation coefficient = 0.644; standard error of measurement = 1.5). The NPQ-Fr has satisfactory basic psychometric properties in patients with chronic spinal pain.     

Effects of neural mobilization in patients after lumbar microdiscectomy due to intervertebral disc lesion

BackgroundNeural mobilization (NM) techniques have been shown to improve the neural tissue's viscoelastic properties that may lead to recover of the function of the nerve after lumbar spine surgery. This study aimed to determine the effects of NM in addition to standard rehabilitation on lumbar and sciatic pain intensity, disability level, and quality of life in patients after receiving a microdiscectomy of the intervertebral lumbar disc (IVD).MethodsTwenty-four participants (age 41.3 ± 8.3 years old) within 3–4 weeks of a microdiscectomy of an IVD were randomly allocated to control (CTRL; n = 12) or NM group (n = 12). The CTRL group received ten standard rehabilitation sessions. The NM group received the same rehabilitation sessions with the addition of NM techniques. The intensity of lumbar and sciatic pain (visual analogue scale), disability level (Oswestry disability index), and health-related quality of life (SF-36 questionnaire) were measured before and after the intervention.ResultsWithin-group analysis revealed a significant reduction in lumbar (p < 0.05) and sciatic pain intensity (p < 0.001), disability level (p < 0.001), and improvement in the physical function and problems, vitality, emotional well-being, and pain SF-36 items (p < 0.05) in both groups. There were no statistical differences between groups in all outcomes.ConclusionA standard rehabilitation protocol alone or in combination with NM techniques are equally effective in reducing pain and disability level, as well as improving quality of life in patients after a microdiscectomy due to intervertebral lumbar disc lesion.     

The reliability and validity of the 30-seconds sit-to-stand test and its capacity for assessment of the functional status of hemodialysis patients

PurposeTo investigate the validity of the 30-seconds sit-to-stand test (STS-30) and its reliability in hemodialysis patients.MethodsPatients receiving hemodialysis treatment three times a week for at least six months were evaluated using STS-30, Incremental Shuttle Walking Test, and health-related quality of life by KDQOL-SF questionnaire. The data obtained from the Incremental Shuttle Walking Test were divided into tertiles, and the STS-30 results were compared among tertiles. The accuracy of the STS-30 to identify low exercise capacity was evaluated. A second STS-30 was performed after 6 to 8-weeks for the reliability analyses using Intraclass Correlation Coefficient (ICC). Minimal detectable change scores were calculated.ResultsSixty-three individuals (66.7% men) aged 48.3 years (95%CI 44.6–51.9) were evaluated. There were significant correlations between STS-30, exercise capacity (r = 0.72), and physical domains of health-related quality of life (0.30 ≤ r ≤ 0.51). Tertile 1 of the Incremental Shuttle Walking Test was different from tertiles 2 and 3 for STS-30 [difference of 3.4 repetitions (95%CI 1.5–5.4) and 4.7 repetitions (95%CI 2.8–6.7), respectively]. The value of 12 repetitions was the cut-off points for stratification of individuals with low exercise capacity. The STS-30 had a high test-retest reliability (ICC = 0.93) and the minimal detectable change was 2.1 repetitions.ConclusionThe STS-30 is a reliable test, associated with exercise capacity and physical domains of health-related quality of life. Thus, is a valid method for functional evaluation in hemodialysis patients.

The nursing critical thinking in clinical practice questionnaire for nursing students: A psychometric evaluation study

AimTo adapt and validate the N-CT-4 Practice for use with Spanish nursing students.BackgroundPromoting critical thinking is one of the primary objectives of nursing education programs all over the world. Using reliable and valid instruments to measure critical thinking is essential. The Nursing Critical Thinking in Clinical Practice Questionnaire (N-CT-4 Practice) is used internationally to assess critical thinking in nursing practice. However, little is known about the possible applications of this instrument in the context of nursing education.MethodsTwo-phase study: Phase I, adaptation of the N-CT-4 Practice for use with nursing students and verification of its content validity; phase 2, cross-sectional study to validate its psychometric properties in a sample of 331 nursing students from three university nursing schools. A subsample of 34 students completed the questionnaire on two occasions, with a time interval of two weeks. The construct validity and reliability of the instrument were tested using confirmatory factor analysis, convergent validity, internal consistency reliability and test-retest reliability. The STROBE guidelines and the COSMIN checklist were followed.ResultsAll items obtained optimal content validity values. The model fit indices obtained from the confirmatory factor analysis supported the hypothesis of the four-dimensional structure on which the original questionnaire was based. Cronbach's alpha of 0.96 indicated high reliability. The correlations between the total score and the scores for the dimensions were statistically significant, positive and high, with values above r = 0.78 (p < 0.05). Lin's concordance correlation coefficient was 0.6 (p < 0.001).ConclusionsThe adapted version of the N-CT-4 Practice is suitable for measuring critical thinking skills in the educational context of the degree course in nursing in Spain. Its psychometric validation yielded satisfactory results.     

Assessing Multisensory Sensitivity Across Scales: Using the Resulting Core Factors to Create the Multisensory Amplification Scale

Multisensory sensitivity (MSS), observed in some chronic pain patients, may reflect a generalized central nervous system sensitivity. While several surveys measure aspects of MSS, there remains no gold standard. We explored the underlying constructs of 4 MSS-related surveys (80 items in total) using factor analyses using REDCap surveys (N = 614, 58.7% with pain). Four core- and 6 associated-MSS factors were identified from the items assessed. None of these surveys addressed all major sensory systems and most included additional related constructs. A revised version of the Somatosensory Amplification Scale was developed, encompassing 5 core MSS systems: vision, hearing, smell, tactile, and internal bodily sensations: the 12-item Multisensory Amplification Scale (MSAS). The MSAS demonstrated good internal consistency (alpha = 0.82), test-retest reliability (ICC_3,1 = 0.90), and construct validity in the original and in a new, separate cohort (R = 0.54–0.79, P < .0001). Further, the odds of having pain were 2–3.5 times higher in the highest sex-specific MSAS quartile relative to the lowest MSAS quartile, after adjusting for age, sex, BMI, and pain schema (P < .03). The MSAS provides a psychometrically comprehensive, brief, and promising tool for measuring the core-dimensions of MSS.PerspectiveMultiple multisensory sensitivity (MSS) tools are used, but without exploration of their underlying domains. We found several measures lacking core MSS domains, thus we modified an existing scale to encompass 5 core MSS domains: light, smell, sound, tactile, and internal bodily sensations using only 12 items, with good psychometric properties.     

Development and Psychometric Testing of a Tool Measuring Nurses’ Competence for Disaster Response

IntroductionThere is a growing awareness among governments, communities, and health care agencies of the need to evaluate roles and competencies in disaster nursing. A validated instrument was developed to evaluate nurses’ competencies for disaster response.MethodsA psychometric evaluation study was developed in 2 stages: 1) content and face validity, and 2) verification of feasibility and reliability with test-retest. Competencies were extracted from the Framework of Disaster Nursing Competencies published by the International Council of Nurses. The participants included 8 experts in emergencies and disasters who were nurses with a PhD and had more than 2 years of experience with education or clinical practice in emergencies or disasters, and 326 nurses from a mobile emergency care service in southern Brazil. The data analysis used a content validity index and intraclass correlation coefficients. The psychometric properties of the instrument included reliability assessed with Cronbach alpha, feasibility and test-retest reliability assessed with t tests and intraclass correlation coefficients, and factor analysis.ResultsThe overall evaluation of the instrument yielded an intraclass correlation coefficient of 0.92 (SD = 0.04), and the mean content validity index was acceptable at 0.88 (SD = 0.12). Out of 51 items, 41 were validated and organized in 3 domains according to factor analysis: 1) care of the community; 2) care of the individual and family; and 3) psychological support and care of vulnerable populations. The instrument demonstrated good internal consistency (Cronbach α = 0.96) and adequate test-retest reliability (intraclass correlation coefficient >0.7).DiscussionThe Nurses’ Disaster Response Competencies Assessment Questionnaire showed good internal consistency, adequate reproducibility, and appropriate feasibility for use to evaluate nurses’ competencies for disaster response.     

Establishing the Reliability,Validity, and Prognostic Utility of the Momentary Pain Catastrophizing Scale for Use in Ecological Momentary Assessment Research

Despite the marked increase in ecological momentary assessment research, few reliable and valid measures of momentary experiences have been established. The goal of this preregistered study was to establish the reliability, validity, and prognostic utility of the momentary Pain Catastrophizing Scale (mPCS), a 3-item measure developed to assess situational pain catastrophizing. Participants in 2 studies of postsurgical pain outcomes completed the mPCS 3 to 5 times per day prior to surgery (N = 494, T = 20,271 total assessments). The mPCS showed good psychometric properties, including multilevel reliability and factor invariance across time. Participant-level average mPCS was strongly positively correlated with dispositional pain catastrophizing as assessed by the Pain Catastrophizing Scale (r = .55 and .69 in study 1 and study 2, respectively). To establish prognostic utility, we then examined whether the mPCS improved prediction of postsurgical pain outcomes above and beyond one-time assessment of dispositional pain catastrophizing. Indeed, greater variability in momentary pain catastrophizing prior to surgery was uniquely associated with increased pain immediately after surgery (b = .58, P = .005), after controlling for preoperative pain levels and dispositional pain catastrophizing. Greater average mPCS score prior to surgery was also uniquely associated with lesser day-to-day improvement in postsurgical pain (b = .01, P = .003), whereas dispositional pain catastrophizing was not (b = −.007, P = .099). These results show that the mPCS is a reliable and valid tool for ecological momentary assessment research and highlight its potential utility over and above retrospective measures of pain catastrophizing.PerspectiveThis article presents the psychometric properties and prognostic utility of a new measure to assess momentary pain catastrophizing. This brief, 3-item measure will allow researchers and clinicians to assess fluctuations in pain catastrophizing during individuals’ daily lives, as well as dynamic relationships between catastrophizing, pain, and related factors.     

The Portuguese version of the musculoskeletal pain intensity and interference questionnaire for musicians (MPIIQM-Pt): Translation,cultural adaptation,and multicenter validation study in professional orchestra musicians

Objectives

We aim to assess the validity and reliability of the Musculoskeletal Pain Intensity and Interference Questionnaire for Musicians (MPIIQM) and to add to its cross-cultural adaptation process by translating, culturally adapting, and validating the MPIIQM into European Portuguese language in the population of Portuguese musicians.

Methods

A Portuguese version of the MPIIQM (MPIIQM-Pt) was created through a process of forward and back translation, pilot testing, and cultural adaptation by expert panel evaluation. The psychometric evaluation was performed in a validation sample of 134 musicians, at baseline and after 7 days.

Results

The high degree of internal consistency and the substantial test–retest reliability coefficients were demonstrated for each subscale (α = 0.896 and ICC = 0.997 for “pain intensity,” and α = 0.879 and ICC = 0.999 for “pain interference,” respectively). Exploratory factor analysis indicated two-factor structure (pain intensity and interference) that explained 75.5% of the variance. Both convergent and divergent validity are well demonstrated, confirming more than 90% of the previously defined hypotheses regarding correlations with other measures.

Discussion

MPIIQM-Pt is the first validated questionnaire to evaluate pain among Portuguese musicians. It showed excellent psychometric properties, both in terms of internal consistency, test–retest reliability, factor analysis, and construct validity. Therefore, it is a valid and reliable tool suitable for both research and clinical practice purposes. MPIIQM-Pt will allow the development of more robust studies on pain among musicians and the improved assessment and monitoring of pain in this population, filling an important gap in this field of Pain Medicine.     

Validation of the Dutch Version of the Breakthrough Pain Assessment Tool in Patients With Cancer

ContextEssential for adequate management of breakthrough cancer pain is a combination of accurate (re-)assessment and a personalized treatment plan. The Breakthrough Pain Assessment Tool (BAT) has been proven to be a brief, multidimensional, reliable, and valid questionnaire for the assessment of breakthrough cancer pain.ObjectivesThe aim of this study was to examine the validity and reliability of the Dutch Language version of the BAT (BAT-DL) in patients with cancer.MethodsThe BAT was forward-backward translated into the Dutch language. Thereafter, the psychometric properties of the BAT-DL were tested, that is factor structure, reliability (internal consistency and test-retest reliability), validity (content validity and construct validity), and the responsiveness to change.ResultsThe BAT-DL confirmed the two-factor structure in 170 patients with cancer: pain severity/impact factor and pain duration/medication efficacy factor. The Cronbach's alpha coefficient was 0.72, and the intraclass correlation for the test-retest reliability was 0.81. The BAT-DL showed to be able to differentiate between different group of patients and correlated significantly with the Brief Pain Inventory. In addition, the BAT-DL was capable to detect clinically important changes over time.ConclusionThe BAT-DL is a valid and reliable questionnaire to assess breakthrough pain in Dutch patients with cancer and is a relevant questionnaire for daily practice.

Children's Perioperative Multidimensional Anxiety Scale (CPMAS): Turkish Validity and Reliability Study

PurposeTo test the validity and reliability of the Turkish version of the Children's Perioperative Multidimensional Anxiety Scale (CPMAS).DesignMethodological research model.MethodsOne hundred children (81% male) aged 7 to 13 years undergoing elective surgery at a tertiary university hospital were included. Self-administered CPMAS and State-Trait Anxiety Inventory-Children were used to collect data at preoperative, operation day, and a month after the operation. Internal consistency, test-retest reliability, parallel form reliability, and content and construct validity of the tools were determined across all three visits.FindingsThe CPMAS demonstrated good test-retest reliability (ICC = 0.51 to 0.78) and good internal consistency (Cronbach's alpha = 0.78 to 0.81). Inter item correlation values were ranged from 0.20 to 0.62 at preoperative, 0.32 to 0.64 on the day of operation and 0.36 to 0.75 at a month after the operation. CPMAS single-factor construct and the explanatory percentages were 0.54 and above. After Pearson correlation analysis, CPMAS was moderately correlated with State-Trait Anxiety Inventory-Children at T1 (r = 0.54, P < .01) and T2 (r = 0.56, P < .01).ConclusionsThe Turkish version of CPMAS has good reliability and validity score. Therefore, it is a suitable instrument to assess perioperative anxiety in 7 to 13 years old children in a clinical setting.     

Development of Knowledge and Attitudes Survey on Pain Management for Korean Long-term Care Professionals

PurposeInappropriate knowledge and attitude toward pain management of professionals has been pointed to be major obstacles to effective pain management in long-term care setting. The purpose of this study was to develop the knowledge and attitudes survey on pain management for Korean long-term care (LTC) professionals (KASP-K).MethodsTo develop the KASP-K, the knowledge and attitudes survey regarding pain developed by Ferrell and McCaffery in 2014 was amended after a review of broad literature and the latest pain management standards. A rigorous validation process of the KASP-K was performed by testing the content validity, item difficulty and discrimination index, construct validity, test–retest reliability, and internal consistency.ResultsThe KASP-K consisted of 22 items and showed a content validity index of >0.7. The average difficulty of the KASP-K was 0.56 and the discrimination index was >0.2. The construct validity of the KASP-K was verified because of the differences in the sum scores depending on pain education (t = 2.30, p = .024). The test–retest reliability was r = .79 (p < .001) and the Cronbach's alpha was 0.73.ConclusionThis preliminary evaluation of the KASP-K demonstrated acceptable validity and reliability. The KASP-K will be able to provide scientific and empirical data regarding the knowledge of and attitude toward pain management by LTC professionals.     

Instrumented assessment of shoulder function: A study of inertial sensor based methods

BackgroundInertial sensors have the potential to provide objective and practical methods to assess joint and limb function in the clinical setting. The aim of this study is to evaluate the psychometric properties of inertial sensor metrics in the assessment of patients with subacromial shoulder pain.Methods25 patients with unilateral subacromial shoulder pain and 50 control subjects were recruited. Assessments were carried out on both shoulders for all participants during a short movement procedure. Patients had assessments repeated after receiving three months of physiotherapy. Inertial metrics evaluated included a smoothness measure and speed and power scores derived from the range of angular velocity and acceleration profiles. Individual shoulder scores and asymmetry scores were both evaluated in terms of reliability, known-group validity, convergent validity and responsiveness.FindingsRegression analysis identified age to be a significant predictor for all scores, therefore an age matched sub-cohort of control subjects was used for comparative analyses. All scores demonstrated inter-rater reliability (ICC = 0.48–0.82), were able to differentiate pathological from healthy shoulders (AUC = 0.62–0.91) and displayed significant changes following treatment. Scores derived from the range of acceleration and velocity profiles demonstrated the largest effect sizes (Cohens d = 0.8–1.35), and displayed the highest correlation with the Oxford Shoulder Score (r = −0.40 – -0.58).InterpretationThe scores investigated demonstrate good psychometric properties and have potential to complement existing methods of assessment in the clinical or research setting. Further work is required to fully understand their clinical relevance and optimise assessment methods and interpretation.     

The Italian version of the Sickness Impact Profile-Roland Scale for chronic pain: cross-cultural adaptation,reliability, validity and sensitivity to change

Purpose.?As no adapted form of the 23-item Sickness Impact Profile (SIP)-Roland Scale for patients with chronic pain has ever been validated in the Italian population, the aim of this study was to translate, culturally adapt and validate an Italian version.

Methods.?The development of the Italian version involved translation and back-translation, a final review by an expert committee and the testing of the pre-final version to establish its correspondence with the original. The psychometric testing included testing reliability by internal consistency (Cronbach's α) and test-retest repeatability (intraclass coefficient correlation; ICC), construct validity by comparison with an 11-point pain intensity numerical rating scale (NRS; Pearson's correlation) and the Short Form Health Survey (SF-36; Pearson's correlation) and sensitivity to change by calculating the minimum detectable change (MDC).

Results.?It took 3 months to obtain a shared version of the scale, which was administered to 243 subjects and proved to be satisfactorily acceptable. It had a high degree of internal consistency (α == 0.860) and test-retest reliability (ICC == 0.972). Construct validity testing revealed a moderate correlation with the NRS (r == 0.418), close correlations with the SF-36 physical subscales and moderate-poor correlations with the mental and social subscales; the MDC was 2.33.

Conclusions.?The SIP-Roland scale was successfully translated into Italian, showing satisfactory psychometric properties. The measure can be recommended for use in research and clinical practice to improve the assessment of physical dysfunction in subjects with chronic pain.     

The hypertension scale of the system of Quality of Life Instruments for Chronic Diseases, QLICD-HY: a development and validation study

AimsThis paper is aimed to develop and validate the hypertension scale of the system of Quality of Life Instruments for Chronic Diseases, QLICD-HY.MethodsThe QLICD-HY instrument was developed based on programmed decision procedures with multiple nominal and focus group discussions and pilot testing. A total of 157 inpatients with hypertension were used to provide the data measuring QOL three times before and after treatment. The psychometric properties of the scale were evaluated with respect to validity, reliability and responsiveness employing correlation and factor analyses, and t-tests.ResultsCorrelation and factor analyses confirmed good construct validity and criterion-related validity when using Short Form (36) Health Survey (SF-36) as a criterion. Test–retest reliability coefficients (Pearson r and intra-class correlation (ICC)) for the overall instrument score and all domains except for the hypertension-specific domain (SPD) (0.75) were higher than 0.80 with a range of 0.75–0.91; the internal consistency α for all domains except for the hypertension-specific domain (0.66) was higher than 0.70. The overall score and scores for most facets within each domain except for the social domain (SOD) had statistically significant changes (t-tests) after treatment with moderate effect sizes.ConclusionQLICD-HY has good validity, reliability, responsiveness and can be used as the quality-of-life instrument for patients with hypertension.     

Comparison of the redundancy, reliability, and responsiveness to change among SF-36, Oswestry Disability Index, and Multidimensional Pain Inventory

OBJECTIVE: To compare the Medical Outcomes Trust Short-Form-36 (SF-36), the Multidimensional Pain Inventory (MPI), and the Oswestry Disability Index (ODI) measures on internal consistency, domain overlap, and responsiveness in detecting changes following multidisciplinary pain treatment. METHODS: 424 patients with chronic pain referred to a multidisciplinary pain center were assessed. Of these, 87 patients were assessed prior to and following treatment. Cronbach's alphas were calculated for each SF-36 and MPI domain, and for the ODI. Canonical correlation and regression analyses (R2) described overlap. Responsiveness to change was computed from treatment effect size and significance. RESULTS: Cronbach's alpha ranged from 0.69-0.92 for MPI domains, from 0.79-0.91 for SF-36 domains, and was 0.86 for the ODI. Three domains overlapped but several were unique (eg, the MPI "significant other" domains; R2 range 0.03-0.16). Significant changes following treatment were observed for the MPI Pain Severity, Interference and Outdoor Work Activities, the SF-36 Physical and Social Functioning, Bodily Pain, and the ODI. CONCLUSION: The MPI, SF-36, and ODI each have good psychometric properties. Three domains overlapped between the MPI and the SF-36: pain, Interference/Social functioning, and mental health. The MPI and the SF-36 each contributed unique domains such as the SF-36 General Health and Vitality domains and the MPI "significant other" and physical activity domains. Several of the MPI domains were among the most sensitive to change. Because of its large normative sample and samples of patients with diverse medical disorders, the SF-36 may be particularly useful to compare chronic pain patients to those with other medical conditions. The ODI has the lowest respondent burden. The MPI and SF-36, although containing much overlapping information, both make unique and complementary contributions to assessing patients with chronic pain.     

Psychometric comparison of single-item,short, and comprehensive depression screening measures in Korean young adults

BackgroundIntegrating long depression-screening instruments into routine clinical practice and research studies is often impractical, necessitating short-item if not single-item measures with comparable psychometric properties.ObjectiveTo examine whether single-item or short depression-screening measures are comparable to a comprehensive screening measure in reliability (i.e., internal consistency and test–retest reliability) and validity (i.e., convergent, concurrent, and predictive validity) in Korean young adults within a Classical Testing Theory framework.MethodA total of 458 students from six nursing colleges in South Korea completed three depression measures: the 20-item Center for Epidemiologic Studies-Depression screening instrument (CES-D; comprehensive measure); the five-item Profile of Mood States-Brief depression subscale (POMS-B depression subscale; short measure); a single-item Likert measure; and a single-item numeric rating scale. Internal consistency reliability was tested by Cronbach's alpha and item-total correlations; test–retest reliability by intraclass correlation coefficient (ICC); convergent validity by correlation with the CES-D; concurrent validity by the correlation with perceived stress level and sleep quality; and predictive validity by receiver operating characteristic curve to predict the two groups with different depression levels.ResultsThe POMS-B depression subscale was comparable to the comprehensive CES-D scale in internal consistency reliability (alpha = .85); test–retest reliability (ICC = .76); and convergent (r = .81 with CES-D), concurrent (r = .64 with perceived stress level, r = .34 with sleep quality), and predictive validity (area under the curve = .88). The two single-item options were not comparable to the comprehensive CES-D.ConclusionThe short POMS-B depression subscale shows an acceptable balance between practical clinical and research needs and psychometric quality.

Brazilian Version of Cancer Fatigue Scale: Validation of the Brazilian Version of Cancer Fatigue Scale in Patients With Breast Cancer

ContextScales to assess the fatigue in patients with cancer may help the clinical decision-making process.ObjectivesThe objective of this study was to cross-culturally adapt and determine the validity of the Brazilian version of Cancer Fatigue Scale.MethodsTranslation and cross-cultural adaptation followed the recommendations of international guidelines. One hundred fifty-one women with breast cancer participated in the validity phase and they filled out the Brazilian version of another instruments (Piper Fatigue Scale Revised, Beck Depression Inventory, Verbal Numerical Rating Scale, and Karnofsky Performance Scale). The measurement properties of reliability, internal consistency, and validity were measured.ResultsThe few discrepancies identified in the back-translation were solved by consensus, and the Cancer Fatigue Scale was successfully translated and cross-culturally adapted. The Brazilian version of Cancer Fatigue Scale showed good stability (test-retest reliability intraclass correlation coefficient = 0.95, 95% CI = 0.94–0.97 and interexaminer reliability intraclass correlation coefficient = 0.98, 95% CI = 0.97–0.99) and good internal consistency (Cronbach's alpha >0.70 for the three subscales/domains). The high correlation was found with Piper Fatigue Scale (r = 0.643) and Beck Depression Inventory (r = 0.509) in terms of validity. However, a reasonable correlation was found with Verbal Numerical Rating Scale (r = 0.302) and Karnofsky Performance Scale (r = −0.324).ConclusionHere, we validated the Cancer Fatigue Scale in breast cancer Brazilian women meaning its use for the identification and evaluation of cancer-related fatigue in patients with breast cancer.
