Psychometric properties of the Japanese version of the Fear-Avoidance Beliefs Questionnaire (FABQ)

Background

The Fear-Avoidance Beliefs Questionnaire (FABQ) is useful for measuring fear-avoidance beliefs in patients with low back pain (LBP); however, no psychometrically validated Japanese version is available. The objective of this study was to evaluate reliability and validity of the Japanese version of the FABQ for use with Japanese workers with LBP.

Methods

This was conducted as a web-based survey. Both confirmatory and exploratory factor analysis were performed to examine domain structure of the Japanese version of the FABQ. For reliability, internal consistency was assessed with Cronbach’s alpha coefficient. For concurrent validity, correlation coefficients between the FABQ and the Pain Catastrophizing Scale (PCS) were calculated. For known-group validity, the relationship between FABQ score and clinical variables such as pain and depression was examined.

Results

Analyses were based on responses of 1,786 adult Japanese workers with LBP. Factor analysis using the principal factor method with promax rotation revealed two factors, work and physical activity, in accordance with the domain structure of the original version of the scale. For reliability, acceptable internal consistency was demonstrated with Cronbach’s alpha coefficient of 0.882 and 0.783 for each subscale. For concurrent validity, significantly moderate correlations were demonstrated between FABQ subscales and PCS subscales (r = 0.30–0.39). For known-group validity, as hypothesized, significantly higher FABQ subscale scores were observed in workers who had stronger pain, who experienced routine work disability with sick leave, who experienced recurrence of LBP, and who had depressed mood.

Conclusions

This analysis showed that the Japanese version of the FABQ is psychometrically reliable and valid to detect fear-avoidance beliefs in Japanese workers with LBP.     

Translation,cross-cultural adaptation,reliability and validity of the Persian version of the ACL-QOL questionnaire in patients with anterior cruciate ligament reconstruction

BackgroundQuality of life (QOL) measures can be used to make sound clinical decisions after reconstruction of the anterior cruciate ligament (ACL). The purpose of the present study was to translate and cross-culturally adapt the Anterior Cruciate Ligament Quality of Life (ACL-QOL) questionnaire into the Persian language and to evaluate its psychometric properties.MethodsThe process of translation and cross-cultural adaptation followed the World Health Organization method. One hundred and forty-five patients with ACL reconstruction (ACL-R) filled out the Persian versions of ACL-QOL and the SF-36 Questionnaire. The measurement properties of internal consistency, agreement, criterion validity, floor and ceiling effects were measured. 40 out of 145 patients with ACL-R completed the Persian version of the ACL-QOL questionnaire twice for the test-retest reliability.ResultsThe questionnaire had high internal consistency (Cronbach's α = 0.96). The intraclass correlation was excellent for reliability and agreement in five domains and overall score (ICC 0.87, 0.74, 0.90, 0.85, 0.81 and 0.89; p < 0.001). The standard error of measurement and the minimum detectable change were found to be 3.28 points and 9.9 points, respectively. There was a strong correlation between each item and the total score of the Persian version of ACL-QOL questionnaire. The questionnaire showed strong and moderate criterion validity (r = 0.61, r = 0.37) with SF-36 physical component score and mental component score, respectively. No ceiling and floor effects were observed.ConclusionsPersian version of the ACL-QOL questionnaire has acceptable reliability and validity and can be used in assessing Iranians quality of life after ACL reconstruction.     

Translation,cross-cultural adaptation,and psychometric properties of the Thai version of the Identification of Functional Ankle Instability (IdFAI-THAI) questionnaire

BackgroundThis study developed a Thai version of the Identification of Functional Ankle Instability (IdFAI-THAI) questionnaire.MethodsTo determine construct validity, 200 participants with a history of lateral ankle sprain completed the IdFAI-THAI, the Modified Thai Lower Extremity Functional Scale (LEFS), the Visual Analog Scale of Instability (VAS-I), and the Thai Foot and Ankle Ability Measure (FAAM). Eight days later, 100 randomly selected participants refilled the IdFAI-THAI to assess test-retest reliability and internal consistency.ResultsThe IdFAI-THAI moderate correlated with the LEFS (r_s = ?0.62), the VAS-I (r_s = 0.62), and the FAAM (r_s = ?0.63 and ?0.69 for the activities of daily living and sports subscales, respectively). The IdFAI-THAI had good test-retest reliability (ICC_2,1 = 0.89) and excellent internal consistency (Cronbach’s alpha = 0.94). Ceiling and floor effects were absent.ConclusionThe valid and reliable IdFAI-THAI can identify chronic ankle instability among Thai speakers in clinical and research settings.     

Association of musculoskeletal pain,fear-avoidance factors,and quality of life in active manual wheelchair users with SCI: A pilot study

Objective: Limited evidence examines the association of psychological factors, such as fear of movement and pain catastrophizing, with musculoskeletal pain patterns in active manual wheelchair users with spinal cord injury (SCI). This study investigated the relationship among musculoskeletal pain, fear avoidance factors, quality of life (QoL), activity and duration of injury in individuals with SCI.

Design: Cross-sectional correlational.

Setting: Community setting.

Participants: Twenty-six individuals with SCI (age?=?42?±?14 years, duration manual wheelchair use?=?17?±?13 years, work/school/volunteer hours/week?=?31?±?14; recreation/sports hours/week 10?±?12).

Outcome Measures: Demographics and self-report measures including the Musculoskeletal Pain Survey (MPS), Wheelchair Users Shoulder Pain Index (WUSPI), Tampa Scale of Kinesiophobia (TSK-11), Pain Catastrophizing Scale (PCS), Fear of Pain (FPQ), Subjective Quality of Life Questionnaire (SQoL), and the Social Interaction Inventory (SII). Spearman’s rho (ρ) assessed correlation among measures.

Results: Strong association existed between age and duration of injury (ρ?=?0.66, P?<?0.001). SQoL offered a strong, direct correlation with age (ρ?=?0.63, P?=?0.01), duration of injury (ρ?=?0.70, P?=?0.001), and strong, inverse relationship with MPStotal (ρ?=??0.66, P?=?0.003) and MPS shoulder subscore (ρ?=??0.64, P?=?0.004). WUSPI demonstrated strong, inverse association with self-reported work hours (ρ?=??0.52, P?=?0.02) and a strong, direct relationship to PCS (ρ?=?0.79, P?=?<0001). PCS demonstrated a strong, inverse relationship to work/school/volunteer hours (ρ?=?0.71, P?<?0.001) and strong association to TSK-11_total (ρ?=?0.61, P?=?0.001). A moderate, inverse relationship was identified for recreational/sports hours and FPQ (ρ?=?0.48, P?=?0.03).

Conclusion: This cyclical relationship of musculoskeletal pain, reduced activity, and maladaptive psychological factors allude to interdependence of factors, supporting the multidisciplinary approach to care.     

Midterm Effect of Mental Factors on Pain,Function, and Patient Satisfaction 5 Years After Uncomplicated Total Knee Arthroplasty

BackgroundThe effects of psychological factors on the short-term outcome after uncomplicated total knee arthroplasty (TKA) have been described in several studies. However, the effects of mental factors on the midterm (5-year) outcome have not been described in the literature. This study was performed to examine the influence of pain catastrophizing, anxiety, depression symptoms, and somatization dysfunction on the outcome of TKA during a 5-year follow-up.MethodsOne hundred fifty patients were enrolled in this prospective study. The following mental parameters were assessed in all patients: pain catastrophizing (Pain Catastrophizing Scale), anxiety (State-Trait Anxiety Inventory), depressive symptoms and somatization dysfunction (Patient Health Questionnaire). The primary outcome measure was postoperative pain on a numerical rating scale. The secondary outcome measures were the Knee Injury and Osteoarthritis Outcome Score and patient satisfaction. Intergroup differences were tested using an independent t-test. Odds ratios were calculated to determine the probability of an unsatisfactory outcome.ResultsAt the 5-year follow-up, only depressive symptoms and somatization dysfunction had a significant effect on postoperative pain (numerical rating scale score). This significant effect was also observed for the different Knee Injury and Osteoarthritis Outcome Score subscales and patient satisfaction (P = .010-.020). Pain catastrophizing and anxiety had only a small effect on the clinical outcome at 5 years postoperatively.ConclusionThe effects of psychopathological factors (depressive symptoms and somatization dysfunction) on the clinical outcome after uncomplicated TKA persist for up to 5 years. Preoperative screening for and subsequent treatment of these psychological disorders may improve patient-reported outcomes after TKA.Level of EvidenceLevel II, diagnostic study.     

Cross-cultural adaptation and validation of the simplified chinese version of the fremantle back awareness questionnaire in patients with low back Pain

Purpose

The Fremantle back awareness questionnaire (FreBAQ) was recently developed as simple and quick tool to assess back-specific body perception in Low back pain (LBP) patients. The aim of the present study was to translate and cross-culturally adapt the Fremantle back awareness questionnaire (FreBAQ) into a Simplified Chinese version (FreBAQ-C), and evaluate the reliability and validity of the FreBAQ-C in patients with non-specific Chronic Low back pain (CLBP).

Methods

The FreBAQ was translated into Chinese according to established methods. Internal consistency was assessed according to Cronbach’s alpha. Test–retest reliability was estimated by Intraclass correlation coefficient (ICC). Construct validity was evaluated by correlations between the FreBAQ-C and Visual analogue scale (VAS), Roland-Morris disability questionnaire (RDQ), Pain catastrophizing scale (PCS), Tampa scale for kinesiophobia (TSK) as well as Hospital anxiety and depression scale (HADS).

Results

A total of 105 participants (38 males and 67 females) were included in this study with the mean age of 54.1 ± 15.6 years, mean duration of LBP of 6.8 ± 4.6 years. The FreBAQ-C total scores were well distributed, with no floor or ceiling effects. Internal consistency was excellent (Cronbach’s alpha = 0.833). ICC of test–retest reliability was good (0.897, 95% confidence interval: 0.852–0.929). The limits of agreement (LOA) ranged from − 5.8 to 6.3. The Standard error of measurement (SEM) and Minimum detectable change (MDC) were 2.16 and 5.99. Construct validity was confirmed by significant correlation of The FreBAQ-C and VAS during motion (r = 0.274, p = 0.005) and rest (r = 0.243, p = 0.012), RDQ (r = 0.377, p < 0.001), PCS (r = 0.439, p < 0.001), and TSK(r = 0.311, p = 0.001).

Conclusions

The FreBAQ-C was demonstrated to have acceptable reliability and validity for patients with non-specific CLBP in Chinese mainland. It will allow evaluating body preception of the back in the Chinese population with CLBP.

     

Rheumatoid Arthritis Patients Achieve Better Satisfaction but Lower Functional Activities as Compared to Osteoarthritis Patients After Total Knee Arthroplasty

Background

Recently, poor patient satisfaction after total knee arthroplasty (TKA) has gained attention mainly in osteoarthritis (OA) patients; however, satisfaction after TKA remains to be understood in rheumatoid arthritis (RA) patients. This study aimed to examine satisfaction and function after RA TKA using patient-reported outcome measures and to compare the results with those of OA-TKA.

Simplified Chinese Version of University of California at Los Angeles Activity Score for Arthroplasty and Arthroscopy: Cross-Cultural Adaptation and Validation

To translate and cross-culturally adapt the University of California at Los Angeles (UCLA) activity score into a simplified Chinese version (UCLA-C) and evaluate the reliability and validity of the UCLA-C for patients with both knee arthroscopy and total knee arthroplasty.

Cross-cultural adaptation and validation of the STarT Back Tool for Arabic speaking adults with low back pain in Saudi Arabia

Background

The STarT Back Tool (Subgrouping for Targeted Treatment; SBT) was developed and validated in the United Kingdom for adults with non-specific low back pain (LBP) to provide risk stratification groups. An Arabic version has not yet been developed. Consequently, our objectives were: First, to cross-culturally adapt the SBT for use in Arabic speaking adults (SBT-Ar) with LBP. Second, to assess the face, content and construct validity of SBT-Ar against relevant reference standards.

Good validity and reliability of the forgotten joint score in evaluating the outcome of total knee arthroplasty: A retrospective cross-sectional survey-based study

Background and purpose — When evaluating the outcome after total knee arthroplasty (TKA), increasing emphasis has been put on patient satisfaction and ability to perform activities of daily living. To address this, the forgotten joint score (FJS) for assessment of knee awareness has been developed. We investigated the validity and reliability of the FJS.

Patients and methods — A Danish version of the FJS questionnaire was created according to internationally accepted standards. 360 participants who underwent primary TKA were invited to participate in the study. Of these, 315 were included in a validity study and 150 in a reliability study. Correlation between the Oxford knee score (OKS) and the FJS was examined and test-retest evaluation was performed. A ceiling effect was defined as participants reaching a score within 15% of the maximum achievable score.

Results — The validity study revealed a strong correlation between the FJS and the OKS (intraclass correlation coefficient (ICC)?=?0.81, 95% CI: 0.77–0.85; p < 0.001). The test-retest evaluation showed almost perfect reliability for the FJS total score (ICC = 0.91, 95% CI: 0.88–0.94) and substantial reliability or better for individual items of the FJS (ICC? 0.79). We found a high level of internal consistency (Cronbach’s? = 0.96). The ceiling effect for the FJS was 16%, as compared to 37% for the OKS.

Interpretation — The FJS showed good construct validity and test-retest reliability. It had a lower ceiling effect than the OKS. The FJS appears to be a promising tool for evaluation of small differences in knee performance in groups of patients with good clinical results after TKA.     

Cross-cultural adaptation and validation of the Behavioral Avoidance Test-Back Pain (BAT-Back) to the Turkish language

ObjectivePain-avoidance is considered to be one of the major leading factors to develop a chronic low back pain (CLBP). In this study, we aimed to translate the Behavioral Avoidance Test-Back Pain (BAT-Back) into Turkish and evaluate its psychometric properties in patients with CLBP.Methods115 patients with CLBP filled the provided socio-demographic information form, the “Oswestry Disability Index (ODI)", the “Fear-Avoidance Beliefs Questionnaire (FABQ)", the “Tampa Scale for Kinesiophobia (TSK)", and the “Hospital Anxiety Depression Scale (HADS)". All patients and 40 pain free controls (PFC) were administered the Turkish version (TrBAT-Back) of the “Behavioral Avoidance Test-Back Pain” test. The internal consistency was evaluated with Cronbach's α coefficient. The test-retest reliability was assessed with the intraclass correlation coefficient (ICC). To evaluate the structural validity of TrBAT-Back, its correlation with FABQ, TSK, ODI, and HADS was examined.ResultsThe internal consistency of TrBAT-Back was excellent (Cronbach's α = 0.97) and its test-retest reliability was good (ICC = 0.87). Its high correlation with the FABQ-physical activity scores and moderate correlation with the TSK scores supported the structural validity. The TrBAT-Back scores showed a statistically significant moderate correlation with the higher level of pain and disability. Despite the low degree of positive correlation, a high level of anxiety (HADS-anxiety) is potentially associated with avoidance behaviour. CLBP patients and controls differed significantly on TrBAT-Back avoidance scores.ConclusionWe are of the opinion that, compared to the self-report scales, TrBAT-Back will provide more objective data in detecting avoidance behaviour associated with pain in Turkish speaking patients with CLBP.     

Reliability,validity and responsiveness of the cross-culturally adapted Italian version of the core outcome measures index (COMI) for the neck

Purpose

Evaluation of the psychometric properties of a cross-culturally adapted questionnaire, the Core Outcome Measurement Index for neck pain (COMI-neck).

Methods

The COMI-neck was cross-culturally adapted for the Italian language using established procedures. The following psychometric properties of the instrument were then assessed in patients with chronic neck pain undergoing rehabilitation: test–retest reliability (intraclass correlation coefficient, ICC); construct validity by comparing COMI-neck with the Neck Pain and Disability Scale, a numerical pain rating scale, and the EuroQol-Five Dimension (Pearson’s correlations); and responsiveness by means of Standardized Response Mean (SRM), unpaired t tests, and Receiver Operating Characteristics (ROC) curves.

Results

The questionnaire was completed by 103 subjects. The COMI-neck summary score displayed no relevant floor or ceiling effects. Test–retest reliability was excellent (ICC = 0.87). With one exception (symptom-specific well-being), the individual COMI items and the COMI summary score correlated to the expected extent with the scores of the reference questionnaires (r = 0.40–0.80). The mean change scores for the Italian COMI-neck differed significantly between patients with a good global outcome and those with a poor outcome (p = 0.002); SRM for the good outcome group was 1.23, and for the poor outcome group 0.40. ROC analysis revealed an area under the curve of 0.73 (95 % CI: 0.62–0.85).

Conclusions

This study provides evidence that the Italian version of the COMI-neck is a valid and responsive questionnaire in the population of patients examined. Its use is recommended for clinical and research purposes.

Validity and reliability of the Swedish version of the Patient Specific Functional Scale in patients treated surgically for carpometacarpal joint osteoarthritis

DesignCross-sectional clinical measurements.IntroductionActivity limitation is often persistent after surgically treated carpometacarpal (CMC) joint osteoarthritis (OA).PurposeTo describe content and concurrent validity, test–retest reliability and internal consistency of the Swedish version of the Patient Specific Functional Scale (PSFS) in patients with surgically treated CMC joint OA.MethodsFifty-eight patients were assessed ten weeks after surgical treatment of CMC joint OA. PSFS, the shorter version of Disabilities of the Arm, Shoulder and Hand (Quick DASH), EuroQol-5Dimensions (EQ-5D), pain intensity, joint movement of CMC joint, grip and pinch strength were assessed. Classification of activities was done according to the International Classification of Functioning, Disability and Health (ICF). Spearman correlation, intra-class correlation coefficient (ICC) and Kappa were calculated to assess validity, test–retest reliability and internal consistency. The PSFS was administered twice, 2–3 days apart.ResultsAll of the activity limitations stated in the PSFS could be classified according to the activity component in the ICF. Significant correlations for the PSFS were obtained with pain at rest (r_s = ?0.36) and the Quick DASH (r_s = ?0.28). Test–retest reliability was good, ICC (0.79) and the three items of the PSFS correlated 0.69–0.83 with the total score of PSFS.ConclusionContent validity was excellent, concurrent validity was low-moderate, as in earlier studies. The PSFS could be a valuable supplement to existing measures in measuring activity limitations in individuals with surgically treated CMC joint OA.Level of evidenceNot applicable.     

Cross-cultural Adaptation of the Patient-rated Tennis Elbow Evaluation to Canadian French

IntroductionNo questionnaire is available to evaluate disability levels in French-speaking patients suffering from tennis elbow.Purpose of the StudyTo perform a cross-cultural adaptation of the English version of the Patient-rated Tennis Elbow Evaluation (PRTEE) into Canadian French.MethodsThe PRTEE was cross-culturally adapted to Canadian French according to well-established guidelines. Thirty-two patients with tennis elbow completed the prefinal version of the PRTEE. The construct validity, longitudinal validity, and responsiveness were assessed through comparisons with the Visual Analog Scale (VAS) measuring pain and the pain-free grip (PFG) at baseline, six weeks and three months. The internal consistency was assessed by Cronbach's alpha and the item-total correlations.ResultsThe adaptation process resolved the discrepancy between the forward and back translation. The scores of PRTEE were adequately distributed without floor or ceiling effect. Item completion was good. The correlation between the PRTEE and the VAS was moderate to high (r = 0.64–0.77) and statistically significant. There was also a low but significant correlation between the PRTEE and PFG (r = ?0.38 to ?0.48). For the longitudinal construct validity, the correlation with the VAS was moderate to high and statistically significant (r = 0.68 and 0.88, p < 0.01). The effect size (0.8; 1.0) and the standardized response mean (0.9; 1.0) were high and at least as good as the other outcomes. Internal consistency of the total score was high (Cronbach alpha = 0.93) and item-total correlations were substantial for all items (0.58–0.85).ConclusionsThis study supports linguistic and conceptual equivalence of our Canadian French version. Because this version of the PRTEE demonstrated good acceptability, construct validity, internal consistency, and responsiveness, it may be used in both research and clinical setting.Level of EvidenceN/A.     

Comparison of Expectations and Outcomes in Rheumatoid Arthritis Versus Osteoarthritis Patients Undergoing Total Knee Arthroplasty

BackgroundWe hypothesized that patients undergoing primary total knee arthroplasty (TKA) for rheumatoid arthritis (RA) would have different preoperative expectations compared to osteoarthritis (OA) patients, and that postoperative satisfaction would correlate with specific postoperative pain and functional domains.MethodsThis is a retrospective cohort study of RA patients matched based on age, gender, American Society of Anesthesiologists score, and Charlson Comorbidity Index score 1:2 with OA patients (76 RA, 152 OA) who underwent primary TKA. The Hospital for Special Surgery Knee Replacement Expectations Survey, Visual Analogue Scale for Pain (VAS), Knee injury and Osteoarthritis Outcome Score (KOOS), and the Short Form-12 (SF-12) were compared at baseline and at 2 years postoperatively. Minimum clinically important differences (MCIDs) were calculated for KOOS and SF-12 subdomains.ResultsPreoperatively, RA patients had lower expectations, worse VAS Pain, and worse KOOS Pain, Symptoms, and Activities of Daily Living (P < .05). However, at 2 years, RA patients had significantly larger improvements in VAS (P = .01) and these 3 KOOS subdomains (P < .05), achieving comparable absolute scores to OA patients. Overall, 86.1% of RA and 87.1% of OA patients were either somewhat or very satisfied with their TKA. Patient satisfaction correlated with VAS Pain and KOOS outcome scores in both groups. RA and OA patients had high rates of achieving MCID in SF-12 physical component scores and all 5 KOOS subdomains. A higher proportion of RA patients achieved MCID in KOOS Symptoms (98.4% vs 77.2%, P < .001).ConclusionRA patients had lower baseline expectations compared to OA patients. However, RA patients had greater improvements in KOOS and SF-12 subdomains, and there was no difference in satisfaction compared to OA patients after TKA.     

Validation of an obstetric quality of recovery scoring tool (ObsQoR-11) after elective caesarean delivery in a developing country: a prospective observational study

BackgroundThe obstetric quality of recovery scoring tool (ObsQoR-11) was developed and validated in the United Kingdom for use after elective and emergency caesarean delivery. Quality of recovery scoring tools validated in one country may not be valid in other countries with significant cultural, socio-economic and linguistic variations. The aim of the current study was to validate a Hindi version of the ObsQoR-11.MethodsIn this prospective observational study, 100 parturients who underwent elective caesarean delivery in a tertiary care obstetric referral university hospital in North India were asked to complete a Hindi version of the ObsQoR-11 scoring tool 24 h after surgery. The performance of the Hindi version of ObsQoR-11 was assessed using measures of validity, reliability, and feasibility.ResultsThe Hindi version of ObsQoR-11 correlated moderately with the global health visual analogue scale (r=0.45, 95% CI 0.27 to 0.59; P <0.0001) and discriminated well between good and poor recovery (mean (SD) score 84.6 (9.4) vs 75.0 (11.2); P <0.0001). The reliability and internal consistency were moderate (Cronbach’s alpha=0.66; Spearman-Brown Prophesy Reliability estimate=0.57) with good repeatability (intraclass correlation coefficient 0.85, 95% CI 0.69 to 0.93; P <0.0001) and no floor or ceiling effects. All parturients completed the questionnaire in a (median (IQR) time of completion of 3 (1.5 – 5.5) min).ConclusionThe Hindi version of the ObsQoR-11 questionnaire is a promising scoring tool to evaluate quality of recovery after elective caesarean delivery. Further research is needed to evaluate the Hindi tool in other institutions in India as well as in other languages.     

Reproducibility and validity of the Japanese version of the Western Ontario Rotator Cuff Index

BackgroundThe Western Ontario Rotator Cuff Index (WORC) is a self-report, disease-specific, quality-of-life assessment tool. Good reliability and validity have been demonstrated with several language versions of the WORC. In this study, the WORC was translated into Japanese, and its reproducibility and validity for use in Japanese patients with rotator cuff disorder were determined.Materials and methodsThe translated version of the WORC was certified by the developer of the original version. Of 78 consecutive Japanese patients with rotator cuff disorder, 75 completed the following questionnaires: the WORC; the Disabilities of the Arm, Shoulder, and Hand (DASH); and the Short Form 36 (SF-36). In total, 50 patients completed the WORC twice within 2–14 days. Internal consistency, test–retest reliability, absolute reliability, and construct validity were assessed.ResultsCronbach’s alpha coefficients ranged from 0.78–0.95, and intraclass correlation coefficients ranged from 0.72–0.84 for the total score as well as scores on all WORC domains. A fixed bias was revealed between the test and retest for the total score and scores of some domains. Limits of agreement (LOA) ranged from ?19.0–27.9 % for the total score on the WORC. Furthermore, the WORC scores correlated with those of DASH (r = 0.63–0.78) and SF-36 (r = ?0.24 to ?0.69).ConclusionsGood test-retest reliability and construct validity were demonstrated for the Japanese WORC, but relatively high absolute measurement errors were observed. LOA values must be considered when using the WORC for individual patients with rotator cuff disorder.     

Psychometric properties of the Japanese version of short forms of the Pain Catastrophizing Scale in participants with musculoskeletal pain: A cross-sectional study

Background

The Pain Catastrophizing Scale (PCS) is a commonly used as measure of pain catastrophizing. The scale comprises 13 items related to magnification, rumination, and helplessness. To facilitate quick screening and to reduce participant's burden, the four-item and six-item short forms of the English version of the PCS were developed. The purpose of the present study was to evaluate the psychometric properties of a Japanese version of the short forms of PCS using a contemporary approach called Rasch analysis.
