Tampa Scale of Kinesiophobia for Heart Turkish Version Study: cross-cultural adaptation, exploratory factor analysis, and reliability

Are the Cross-Culturally Adapted Versions of the Tampa Scale for Kinesiophobia 11-Item Valid, Reliable, and Responsive? A COSMIN-Informed Systematic Review of Measurement Properties

Numerous cultural adaptations of the Tampa Scale of Kinesiophobia 11-item version (TSK-11) scale have emerged since the original version was introduced. We conducted a (COnsensus-based Standards for the selection of health Measurement INstruments) COSMIN-informed systematic review of measurement properties to identify the cross-cultural adaptation of the TSK-11 and report, critically appraise, and systematize its measurement properties. Six databases were searched for studies published since 2005. Studies reporting on the measurement properties of culturally adapted versions of the TSK-11, published in English, Portuguese, and Spanish, were considered for inclusion. The results were synthesized by measurement properties and rated against the COSMIN criteria for good measurement properties. The quality of the evidence was assessed using the Grading of Recommendations, Assessment, Development, and Evaluation approach and presented in a summary of findings table. Twenty-three studies were included, and cultural adaptations for 15 languages were identified: English, Chinese, Cantonese, Swedish, German, Dutch, Arabic, Turkish, Danish, Spanish, Japanese, Brazilian Portuguese, Marathi, Thai, and Persian. There is "high" certainty in the evidence for "sufficient" criterion validity (TSK-17, r = .84) and "insufficient" measurement error (small detectable change range 5.6-6.16). "Moderate" certainty in the evidence for "sufficient" construct validity (87.8% of hypotheses confirmed), test-retest reliability (intraclass correlation coefficient2,1 = .747-.87), and "low" certainty in evidence for "sufficient" responsiveness. The numerous sources of heterogeneity prevent conclusions from being drawn regarding structural validity. Measurement error, responsiveness, and structural validity of the TSK-11 require further investigation. Clinicians should complement the use of TSK-11 with other instruments. Future studies on the structural validity of the questionnaire should standardize the data analysis methods. PERSPECTIVE: This article presents the measurement properties of the cross-cultural adaptations of the TSK-11. Clinicians should be aware that cultural and clinical aspects may influence the structural validity of the questionnaire. Using the TSK-11 as a stand-alone instrument may omit relevant clinical progression in the patient's condition.

The Spanish adaptation of the Tampa Scale for Kinesiophobia Heart: psychometric evidence in cardiac rehabilitation patients

BACKGROUND

The factor structure of the Tampa Scale of Kinesiophobia Heart version has rarely been adequately analyzed. We aimed to evaluate the psychometric properties of this scale through a variety of exploratory and confirmatory factorial approaches.

AIM

To perform a translation, cross-cultural adaptation, and psychometric evaluation of the Spanish version of the Tampa Scale of Kinesiophobia Heart in patients attending Cardiac Rehabilitation (TSK-SPA).

DESIGN

Cross-sectional study.

SETTING

A Cardiac Rehabilitation unit.

POPULATION

Adults with the principal diagnosis of coronary artery disease (83%) who were referred to Cardiac Rehabilitation (N.=194; mean age, 64.28±9.2; 15% women).

METHODS

We performed a translation and a cross-cultural adaptation of the TSK-SPA. The psychometric properties of validity comprising the face, content, and construct validity were then tested. Five factorial models were proposed to analyze the data structure. We examined the validity evidence of the TSK-SPA based on the relationships with other analyzed variables using the SF12 quality of life Questionnaire, the International Physical Activity Questionnaire, the Hospital Anxiety and Depression Scale and the Beck Depression Inventory. The reliability tests included internal consistency and stability over time.

RESULTS

The results suggested a four-dimensional structure. Models with more than 1 dimension exhibited undesirable factor loadings or inadequate fit indices. Based on these results, a short version of the scale with 13 items is proposed. In terms of reliability, the TSK-SPA Heart was found internally consistent (α=0.79) and stable over time (test-retest = 0.82). An Exploratory Structural Equation Modeling (ESEM) analysis provided an acceptable fit for a hypothesized 4-factor model with the inclusion of a method factor: the root mean squared error of approximation was <0.05 (RMSEA = 0.046), and the comparative fit indices were >0.95 or close (CFI=0.994, TLI=0.934). Significant positive correlations were observed between the TSK-SPA scores and the measures of anxiety and depression, with correlation coefficients ranging from 0.35 to 0.48.

CONCLUSIONS

A best-fitting model was identified, and the proposed 13-item TSK-SPA Heart showed sufficient evidence of validity and reliability for Spanish patients with cardiovascular disease. The scale's overall reliability is deemed acceptable, although the factor reliability could be further enhanced.

CLINICAL REHABILITATION IMPACT

Using this questionnaire on fear or avoidance of movement will improve our understanding of cognitive-behavioral factors in patients with cardiovascular disease, aiding their rehabilitation and optimizing their prognosis.

Incidence and influencing factors of kinesiophobia in patients with chronic heart failure: a scoping review

Introduction

Kinesiophobia denotes an excessive and irrational apprehension towards physical activity or exercise among patients, stemming from a perception of susceptibility to painful injury or re-injury. Cardiac rehabilitation stands pivotal in the secondary prevention spectrum for individuals with cardiovascular ailments, with exercise constituting a cornerstone of this regimen. However, the emergence of kinesiophobia poses a formidable challenge, diminishing patient adherence to cardiac rehabilitation protocols, particularly among those grappling with chronic heart failure. To bolster exercise-based rehabilitation initiatives in this cohort, a thorough comprehension of the multifaceted factors precipitating kinesiophobia is imperative. This review endeavors to delineate prevailing evidence and prevalence concerning kinesiophobia triggers in chronic heart failure patients, while pinpointing research lacunae for future exploration.

Methods

Employing a scoping review methodology, our investigation culled data from diverse scholarly databases, including Embase, PubMed, Scopus, CINAHL, Web of Science, Medline, Sinomed, CNKI, Wangfan, and VIP.

Results

After thorough evaluation, 9 studies that met the inclusion criteria were ultimately incorporated.

Discussion

Our findings underscore a notable prevalence of kinesiophobia in chronic heart failure patients, predominantly influenced by socio-demographic factors, psychological and cognitive factors, disease and treatment factors, as well as lifestyle and behavior. Armed with these insights, future interventions can be tailored to mitigate kinesiophobia levels, fostering enhanced engagement in exercise-centric cardiac rehabilitation endeavors among patients grappling with chronic heart failure.

The effect of fear-avoidance intervention on kinesiophobia and self-efficacy in patients after percutaneous coronary intervention: study protocol for a clinical randomized controlled trial

BACKGROUND

Kinesiophobia after percutaneous coronary intervention (PCI) may lead to decreased compliance with rehabilitation exercises. Effective interventions are essential to overcome kinesiophobia after PCI. The aim of this trial is to investigate the clinical effects of an intervention based on the fear-avoidance model (FAM) on kinesiophobia in post-PCI patients.

METHODS

Eighty participants will be recruited in the Department of Cardiology in Hebei Provincial People's Hospital. And they will be randomly allocated to the test group and undergo a 5-day step-to-step intervention. The primary outcome will be the scores of a scale on kinesiophobia. Secondary outcome measures included self-efficacy for exercise, psychogenic anxiety, and the occurrence of cardiovascular adverse events. Primary and secondary outcome data will be collected at baseline (t0), on the day of discharge (t1), and one month after discharge (t2).

DISCUSSION

The effectiveness of an intervention based on the FAM to increase exercise self-efficacy and decrease kinesiophobia in post-PCI patients will be demonstrated. The findings of this study will facilitate post-PCI patients to participate in cardiac rehabilitation.

Fear of Movement in People With CRPS: A Psychometric Evaluation of the Tampa Scale-11 for Kinesiophobia

BACKGROUND

People with complex regional pain syndrome (CRPS) commonly report a fear of movement that can worsen symptoms and increase disability. The Tampa Scale of Kinesiophobia (TSK) is used to evaluate fear of movement and (re)injury, but findings have been inconsistent in different populations.

OBJECTIVE

To evaluate the psychometric properties of the Persian version of TSK-11 in individuals with upper limb CRPS. Specifically, to determine whether the factor structure aligns with the original 2-factor model, consisting of "activity avoidance" and "somatic focus."

MATERIALS AND METHODS

People with CRPS (n=142, mean age=42, 54% female) completed the TSK. The psychometric testing included internal consistency, test-retest reliability (intraclass correlation coefficient), and convergent construct validity. Confirmatory and exploratory factor analyses were performed to evaluate the structural validity.

RESULTS

The TSK-11 showed acceptable internal consistency (Cronbach alpha 0.93) and excellent test-retest reliability (intraclass correlation coefficient=0.93, 95% CI: 0.92-0.94). The Standard Error of Measurement and Minimal Detectable Change were 4.3 and 11.7, respectively. The results also demonstrated excellent criterion validity ( r =0.81). Confirmatory factor analysis demonstrated that the original 2-factor model did not fit. Exploratory factor analysis derived a 2-factor solution with different items. The factor structure accounted for 64.91% of the variance, and the internal consistency of the factors was acceptable (>0.90). Expert consensus suggested naming these 2 factors as fear avoidance and magnification and helplessness.

DISCUSSION

The TSK-11 demonstrates excellent retest reliability in people with CRPS. The original 2-factor structure was not confirmed, and a new 2-factor structure of the TSK-11 was proposed consisting of subscales for Fear Avoidance Beliefs and Magnification/Helplessness. Given the overlap between these constructs and the construct of pain catastrophizing, further study is needed to clarify both measures' content validity and relative uniqueness.

Measurement properties of assessment tools of Kinesophobia in patients with cardiovascular disease: A systematic review

Objectives

This study aimed to evaluate the measurement properties and methodological quality of assessment tools for Kinesophobia among patients with cardiovascular disease and provide a reference for healthcare professionals in selecting high-quality assessment tools.

Methods

A systematic search was performed on specific databases: Embase, the Cochrane Library, PubMed, Web of Science, China National Knowledge Infrastructure, Wanfang database, China Biological Medicine disc, CINAHL, and China Science and Technology Journal Database, from inception to April 1, 2023. The researchers retrieved studies on the measurement attributes of the exercise fear scale in patients with cardiovascular diseases. They also traced back the references of the included studies to supplement relevant literature. According to the inclusion and exclusion criteria, screening and data extraction were independently undertaken by two reviewers. Two researchers individually used the Consensus-based Standards for the selection of health Measurement Instruments (COSMIN) Risk of Bias Checklist to assess the methodological quality of the scale, applied the COSMIN criteria to evaluate the measurement properties of the scale, and used a modified Grading, Recommendations, Assessment, Development, and Evaluation system to assess the certainty of evidence.

Results

Seventeen studies were identified that reported the psychometric properties of six patient reported outcome measurement tools (included different languages version) The methodological quality of content validity was adequate in only two studies, the remaining patient-reported outcome measures demonstrated doubtful content validity. Limited information on cross-cultural validity/measurement invariance, measurement error, and responsiveness was retrieved. The Swedish version and the Chinese version of the Tampa Scale for Kinesiophobia Heart were graded "A." The remaining instruments were graded "B."

Conclusions

The methodological and measurement attributes of the Swedish and Chinese versions of the Tampa Scale for Kinesiophobia Heart are relatively high quality and can be tentatively recommended. The measurement properties of the remaining scales remain to be verified.

Kinesiophobia and Associated Factors in Patients With Myocardial Infarction

Kinesiophobia is a well-known barrier to positive clinical outcomes among patients with various diseases, but there remain few comprehensive studies of kinesiophobia among patients with myocardial infarction (MI). In this cross-sectional study, we investigated the presence of kinesiophobia and its relationship with clinical outcomes among 42 patients with MI who completed the Tampa Scale of Kinesiophobia Swedish Version for Heart (TSK-SV Heart) the International Physical Activity Questionnaire-Short Form (IPAQ-SF), the Six-Minute Walk Test (6MWT), the Hospital Anxiety and Depression Scale (HADS), the modified Medical Research Council (mMRC) Dyspnea Scale, the Charlson Comorbidity Index (CCI), and the MacNew Heart Disease Health-Related Quality of Life Questionnaire. The participants' mean TSK-SV Heart score was 39.24 (SD = 6.65), and 71.4% of these patients reported a high level of kinesiophobia. The TSK-SV Heart score demonstrated a strong correlation with the IPAQ-SF, 6MWT walking distance, and mMRC score (p < .001), and a moderate correlation with the HADS, CCI, and MacNew Heart Disease HRQoL (p < .05). Patients with a high level of kinesiophobia had lower IPAQ-SF, 6MWT walking distance, and HRQoL and higher mMRC, CCI, and HADS scores than patients with low levels of kinesiophobia (p < .05). Kinesiophobia was common and represented a considerable risk factor for physical-psychosocial dysfunctions in these patients with MI. To maintain functional independence and to increase physical activity level, clinicians should consider kinesiophobia from early to late-stage disease and should add a treatment focus that seeks to eliminate kinesiophobia in cardiac rehabilitation programs.

Correlates of musculoskeletal pain and kinesiophobia in older adults with heart failure: A structural equation model

The study aimed to study the influence of musculoskeletal pain on kinesiophobia in patients with heart failure. This cross-sectional study recruited 107 heart failure patients aged 73.18±12.68 years (57% men) from an outpatient setting. Participants self-reported pain using the Musculoskeletal System Assessment Inventory and the Cornell Musculoskeletal Discomfort Questionnaire. Kinesiophobia was assessed with the Tampa Scale for Kinesiophobia-11. About 62% reported musculoskeletal pain, with knees (16.8%) and lower back (12.%) being the most painful locations. About 31% reported moderate levels and 24% indicated high levels of kinesiophobia. There were positive and significant associations between the indicators of pain and kinesiophobia. Results showed an adequate structural equation model fit to the data with musculoskeletal pain factors explaining 22.09% of the variance in kinesiophobia. Assessment of kinesiophobia in patients with heart failure with musculoskeletal pain is essential to improve self-care and overall quality of life.

Kinesiophobia and its associated factors in patients with coronary heart disease: a cross-sectional study based on latent feature analysis

OBJECTIVES

The aim of this study was to explore the current situation of kinesiophobia in patients with coronary heart disease, classify it based on potential profile analysis and explore the relevant factors of kinesiophobia in different categories of patients with coronary heart disease.

DESIGN

Cross-sectional study.

SETTING

Patients with coronary heart disease in China.

PARTICIPANTS

Adult (aged >18 years) patients with coronary heart disease in China; 252 participants in this study answered the questionnaire.

PRIMARY AND SECONDARY OUTCOME MEASURES

The study investigated the scores of Tampa Scale for Kinesiophobia Heart, and collected information on the patient's age, gender, monthly household income, education level, place of residence, marital status, occupational status, hypertension, diabetes, heart failure and body mass index (BMI).

RESULTS

Kinesiophobia in patients with coronary heart disease can be divided into low fear type (C1), intermediate fear type (C2) and high fear type (C3). Elderly patients were classified as type C3. Women and patients with a normal BMI were classified as type C1; patients with a normal BMI and patients with an overweight BMI were classified as type C2.

CONCLUSION

Kinesiophobia of patients with coronary heart disease can be divided into three categories, and intervention measures are implemented according to their different demographic characteristics to reduce kinesiophobia of patients and promote the participation of patients in exercise rehabilitation.

The vicious cycle of physical inactivity, fatigue and kinesiophobia in patients with fibromyalgia syndrome

This study aims to determine the association between fatigue, kinesiophobia, disease severity, and physical inactivity by comparing fibromyalgia syndrome (FMS) patients with healthy controls. Pain and fatigue are significant barriers to the participation in functional activities. Inactivity is a result of fatigue, but exercise is the foundation of FMS treatment. This case-control study included a total of 203 participants (107 patients with FMS and 96 healthy volunteers). The fibromyalgia impact questionnaire, the fatigue severity scale, the international physical activity questionnaire, and the Tampa scale for kinesiophobia were assessed. The FMS group scored significantly higher on the fatigue severity scale and kinesiophobia than the control group (p<0.001). Significantly lower metabolic task equivalent (MET) scale values were observed in the FMS group compared to the control group (p<0.001). The severity of fatigue and kinesiophobia correlated positively with the FMS impact questionnaire (p=0.001, r=0.621) and negatively with the MET scale (p=0.009, r= -0.287). Patients with FMS experience greater fatigue, kinesiophobia, and inactivity. As the severity of FMS worsens, so do disability, kinesiophobia, and fatigue. This study highlights the importance of breaking the cycle of fatigue and inactivity in the treatment of FMS.

The best structure of the Tampa Scale for Kinesiophobia for patients with chronic low back pain has two domains and nine items

PURPOSE

To identify the best internal structure of the Tampa Scale for Kinesiophobia in chronic low back pain patients.

DESIGN

Questionnaire validation study was designed for this study.

SETTING

This study was conducted in physical therapy facility.

SUBJECTS

Respondents reporting chronic low back pain (≥3 points on the 11-point Numerical Pain Rating Scale).

MAIN MEASURES

We included participants of both sexes, with a self-report of low back pain ≥3 months and with pain intensity ≥3 on the 11-point Numerical Pain Rating Scale; participants also answered the Roland-Morris Disability Questionnaire and the Pain-Related Catastrophizing Thoughts Scale for low back pain disability and catastrophizing, respectively. The dimensionality and number of items of the Tampa Scale for Kinesiophobia were evaluated using the confirmatory factor analysis. Criterion validity was assessed using Spearman's correlation coefficient using the original version of the 17-item Tampa Scale for Kinesiophobia as the gold standard.

RESULTS

A total of 122 participants were included, with mean values of low back pain duration ≥48 months, pain intensity >5 and disability >8. Tampa Scale for Kinesiophobia structure with two domains and nine items was the most suitable, with adequate values in all fit indices (Chi-square/degree of freedom <3, Comparative Fit Index and Tucker-Lewis Index >0.90, and root mean square error of approximation <0.08) and lower Akaike information criterion and Bayesian information criterion values. We observed a high correlation between the 17-item Tampa Scale for Kinesiophobia and the activity avoidance domain (rho = 0.850, P < 0.001) and somatic focus domain (rho = 0.792, P < 0.001) of the nine-item Tampa Scale for Kinesiophobia.

CONCLUSION

Tampa Scale for Kinesiophobia structure with two domains (activity avoidance and somatic focus) and nine items is the most suitable for patients with chronic low back pain.

Kinesiophobia, physical performance, and health-related quality of life in patients with coronary artery disease

Introduction

Kinesiophobia is an important risk factor for physical activity and exercise restrictions. It is important to assess kinesiophobia and identify high-risk patients to help prevent sedentary behaviour and increase exercise participation among cardiac patients.

Aim

To evaluate kinesiophobia and its association with physical performance, health-related quality of life (HRQOL), patients' limitations and symptoms, and disease history in patients with coronary artery disease (CAD).

Material and methods

Fifty-two patients diagnosed with CAD were enrolled in this study. Kinesiophobia was assessed with the Tampa Scale of Kinesiophobia for Heart. The 5× Sit-to-Stand Test (5-STST), the Timed Up and Go Test (TUGT), and the 6-Minute Walk Test (6-MWT) were used to assess physical performance. Patients' limitations and symptoms and HRQOL were evaluated with the Cardiovascular Limitations and Symptoms Profile. CAD duration and history of myocardial infarction (MI) were also recorded.

Results

87.2% of the patients had high level of kinesiophobia, which was higher in patients with previous MI compared to patients without history of MI (p = 0.031). Kinesiophobia was positively correlated with 5-STST duration, TUGT duration, angina, shortness of breath, HRQOL, and CAD duration, and it was negatively correlated with 6-MWT distance (p < 0.05). According to regression analysis, only angina was a significant predictor for kinesiophobia (p = 0.014). Kinesiophobia was found to be a predictor of physical performance and HRQOL (p < 0.05).

Conclusions

Levels of kinesiophobia are high in patients with CAD, especially in those with a history of MI. Angina is a predictor of kinesiophobia while kinesiophobia is a predictor of both physical performance and HRQOL in CAD patients.

Kinesiophobia and its association with functional outcome and quality of life 6-8 years after total hip arthroplasty

OBJECTIVE

The aim of this study was to assess the incidence and severity of kinesiophobia, and to determine the relationship between Tampa Scale of Kinesiophobia (TSK) scores, functional outcome and quality of life (QoL) 6-8 years after Total Hip Arthroplasty (THA).

METHODS

161 patients (78 male and 83 female) with unilateral primary osteoarthritis (OA) treated with THA between September 2010 and December 2013 were included in this study. Western Ontario and McMaster Universities Osteoarthritis (WOMAC) and EQ-5D scores were measured preoperatively. At 6-8 years follow-up, these scores were repeated and TSK scores were also measured. According to the TSK, patients were divided into two groups for further comparisons and analysis: without kinesiophobia (TSK-score ≤ 36) and with kinesiophobia (TSK-score >36).

RESULTS

There were 99 patients (61.5%) with no kinesiophobia (TSK score ≤ 36, TSK mean 28.4, SD 4.7) and 62 patients (38.5%) with kinesiophobia (TSK score > 36, TSK mean 42.8, SD 5.3). Patients with and without kinesiophobia were not statistically different regarding age, sex or body mass index. (P = 0.20, P = 0.99, P = 0.22, respectively). In the group with no kinesiophobia, the mean 6-8 years WOMAC was 12.4 (SD 15.6), while the absolute delta (Δ) value between preoperative and 6-8 years WOMAC was 46.2 (SD 20.4), compared to the group with kinesiophobia where the mean 6-8 years WOMAC was 32.2 (SD 23.4), while the absolute delta (Δ) value between preoperative and 6-8 years WOMAC was 32.3 (SD 25.5): both P < 0.001. The group with no kinesiophobia had a mean 6-8 years EQ-5D of 0.81 (SD 0.22), while the absolute delta (Δ) value between preoperative and 6-8 years EQ-5D was 0.44 (SD 0.26), compared to the group with kinesiophobia where the mean 6-8 years EQ-5D was 0.57 (SD 0.23), while the absolute delta (Δ) value between preoperative and 6-8 years EQ-5D was 0.33 (SD 0.26): P < 0.001 and P = 0.03, respectively. TSK scores were associated with worse WOMAC and EQ-5D scores, higher proportion of dependence on walking aids and increased THArelated adverse events (all P < 0.05).

CONCLUSION

This study has shown us that there is a high incidence of kinesiophobia 6-8 years after surgery and treating kinesiophobia early after THA might improve the outcome.

Fear of Movement/(Re)Injury: An Update to Descriptive Review of the Related Measures

The prevalence of fear of movement (kinesiophobia) in persistent pain ranges from 50 to 70%, and it may hinder the subsequent rehabilitation interventions. Therefore, the evaluation of fear of movement/(re)injury plays a crucial role in making clinical treatment decisions conducive to the promotion of rehabilitation and prognosis. In the decision-making process of pain treatment, the assessment of fear of movement/(re)injury is mainly completed by scale/questionnaire. Scale/questionnaire is the most widely used instrument for measuring fear of movement/(re)injury in the decision-making process of pain treatment. At present, the most commonly used scale/questionnaire are the Tampa Scale for Kinesiophobia (TSK), the Fear-Avoidance Beliefs Questionnaire (FABQ), the Kinesiophobia Causes Scale (KCS), the Athlete Fear-Avoidance Questionnaire (AFAQ), and the Fear-Avoidance Components Scale (FACS). In order to provide necessary tools and references for related research and rehabilitation treatment, this descriptive review is designed as an introduction to the background and content, score system, available language versions, variants of the original questionnaire, and psychometric properties of these scales/questionnaries.

The effect of cardiac rehabilitation on kinesiophobia in patients with coronary artery disease

Objectives

The aim of this study was to define the level of kinesiophobia in cardiac patients, to determine whether there was a positive change in kinesiophobia after an exercise based cardiac rehabilitation (CR), and to define the associated variables with the change in kinesiophobia.

Patients and methods

Between September 2017 and December 2018, a total of 98 patients (63 males, 35 females; mean age: 58±10.4 years; range, 36 to 78 years) diagnosed with coronary artery disease (CAD) were included in the study. The Tampa Scale for Kinesiophobia Heart (TSK-SV Heart) was used to measure kinesiophobia. The short form of the International Physical Activity Questionnaire (IPAQ) was applied to measure physical activity level. The Short Form 36 (SF-36) was used to measure health-related quality of life (HRQoL). After CR, kinesiophobia was reevaluated.

Results

A high level of kinesiophobia was present in 74.5% of the patients. The mean TSK-SV heart score was 41.4±6.2. After CR, 34.6% of the patients had a high level of kinesiophobia (p<0.001). The patients with a high level of kinesiophobia were physically more inactive than those with a low level of kinesiophobia (p=0.001) and HRQoL scores were significantly lower (p<0.05).

Conclusion

Kinesiophobia is quite common in patients with CAD. Aerobic exercise capacity and physical activity levels are lower in patients with a high level of kinesiophobia, compared to those with a low level of kinesiophobia. After an exercise-based CR program, kinesiophobia significantly reduces.

New Factor Structure of the Tampa Scale for Kinesiophobia in Older Japanese Adults After Lumbar Surgery

Purpose

The Tampa Scale for Kinesiophobia (TSK) has been used worldwide as a measure of kinesiophobia, but its factor structure in older Japanese adults after lumbar surgery is unknown. The purpose of this study was to fill this research gap by identifying the factors that comprise TSK in older Japanese adults after lumbar surgery.

Patients and Methods

Participants were older Japanese adults who had undergone surgery for lumbar spinal stenosis. Clinicodemographic data, TSK, intensity of low back pain and leg pain, dysesthesia (using an 11-point numerical rating scale), and HRQOL (using the EQ-5D-5L) were collected. After supplementing the missing values by the multiple assignment method, the hypothetical model of TSK was developed by categorical exploratory factor analysis (weighted least squares method, promax rotation). Confirmatory factor analysis (WLSMV method, promax rotation) was used to compare the hypothetical model and the traditional one-factor and two-factor models. Furthermore, we confirmed the relationship between factors extracted from the hypothetical model and HRQOL, pain, and dysesthesia.

Results

Questionnaires were mailed to 302 individuals, and responses were obtained from 211 (72.4±4.2 years [range: 65–88]; 115 men and 96 women; 804±343.1 [380–1531] days after surgery; 137 who had undergone decompression and fixation surgery, 74 who had undergone decompression surgery) (response rate: 69.9%). The hypothesized model consisted of “somatic focus,” “activity avoidance,” and “efficacy of physical activities,” all of which were highly consistent. The fit of the hypothetical model was slightly inferior to that of the traditional two-factor model, but the hypothetical model met the criteria for fit. Somatic focus in the hypothetical model was significantly associated with HRQOL, pain, and dysesthesia.

Conclusion

In older Japanese adults after lumbar surgery, the goodness of fit of the TSK model was maintained by adding efficacy of physical activities as a third factor to the traditional two factors.

Convergent Validity of the Central Sensitization Inventory in Chronic Whiplash-Associated Disorders; Associations with Quantitative Sensory Testing, Pain Intensity, Fatigue, and Psychosocial Factors

OBJECTIVE

Central sensitization is present in different pain conditions, including chronic whiplash-associated disorders. In the absence of a gold standard method of assessment to determine the presence of central sensitization, quantitative sensory testing is currently understood as an optimal proxy. Laboratory sensory testing is, however, not feasible in clinical practice, and the Central Sensitization Inventory was developed as an alternative. The aim of the current study was to evaluate the convergent validity of the Central Sensitization Inventory in chronic whiplash-associated patients by determining the association between the Central Sensitization Inventory and quantitative sensory testing, pain intensity, fatigue, and psychosocial factors.

METHODS

A total of 125 chronic whiplash-associated patients completed multiple questionnaires and were subjected to pressure pain thresholds and temporal summation.

RESULTS

. The Central Sensitization Inventory showed a strong association with constructs of general psychopathology, anxiety, distress, depression, and somatization in chronic whiplash-associated disorders. Moderate correlations were found with fatigue and intrusive and avoidant phenomena after a variety of traumatic events. No significant association was found between the Central Sensitization Inventory and pressure pain thresholds and temporal summation, nor between the Central Sensitization Inventory and other pain measurements.

CONCLUSIONS

Overall, we found that the Central Sensitization Inventory is better in identifying the psychosocial factors related to central sensitization in chronic whiplash-associated disorders than the central nervous system adaptations. Thus, the convergent validity of the Central Sensitization Inventory appears to be only partially present in chronic whiplash-associated disorders.

Psychometric Features of the Polish Version of TSK Heart in Elderly Patients with Coronary Artery Disease

Background and objectives: Recommendations for the control of stable patients with coronary artery disease (CAD) related to an adequate level of physical activity (PA). Practical experience shows that the PA level in most people with CAD is definitely too low in relation to the guidelines. The cause may be psychological factors and among them the fear of movement-kinesiophobia. The aim of this project was to examine the evaluation of psychometric features of the Polish version of the Tampa Scale for Kinesiophobia Heart (TSK Heart), used in people with CAD. Materials and methods: The study involved 287 patients with stable CAD: 112 women and 175 men. Age: 63.50 (SD = 11.49) years. Kinesiophobia was assessed using TSK Heart, physical activity (PA)-using the International Physical Activity Questionnaire (IPAQ), and anxiety and depression was examined using the Hospital Anxiety and Depression Scale (HADS). The structure of TSK was examined using principal component analysis (PCA), internal cohesion (Cronbach's alpha, AC), and content validity was calculated by linear regression. Results: PCA showed a three-factor TSK structure. One-dimensionality and satisfactory reliability were found: TSK Heart: AC = 0.878. Kinesiophobia as a predictor of PA: R2 = 0.162 (p = 0.000000). Anxiety and depression-TSK: R2 = 0.093 (p = 0.00000). Conclusions: The Polish version of TSK Heart for cardiac patients is characterized by good psychometric features. The use of it can improve the cooperation of rehabilitation teams for patients with CAD.

Measuring successful aging: an exploratory factor analysis of the InCHIANTI Study into different health domains

Advocating continued health into old age, so called successful aging, is a growing public health goal. However, the development of tools to measure aging is limited by the lack of appropriate outcome measures, and operational definitions of successful aging. Using exploratory factor analysis, we attempted to identify distinguishable health domains with representative variables of physical function, cognitive status, social interactions, psychological status, blood biomarkers, disease history, and socioeconomic status from the InCHIANTI study. We then used logistic and mixed effect regression models to determine whether the resulting domains predicted outcomes of successful aging over a nine-year follow-up. A four-domain health model was identified: neuro-sensory function, muscle function, cardio-metabolic function and adiposity. After adjustment for age and gender, all domains contributed to the prediction of walking speed (R²=0.73). Only the muscle function domain predicted dependency (R²=0.50). None of the domains were a strong, significant predictor of self-rated health (R²=0.18) and emotional vitality (R²=0.23). Cross-sectional findings were essentially replicated in the longitudinal analysis extended to nine-year follow-up. Our results suggest a multi-domain health model can predict objective but not subjective measures of successful aging.

The scale was applied to patients who had myocardial infarction, coronary artery bypass grafting, or percutaneous coronary intervention within the last 12 months (N=250).

INTERVENTIONS

A scale for fear of activity in patients with coronary artery disease (Fact-CAD) was created through semistructured focus group interviews with patients. Face and content validity of Fact-CAD was verified.

MAIN OUTCOME MEASURES

Psychometric analysis included model fit, unidimensionality, reliability, local dependency, differential item functioning, and external construct validity. Analyses were performed using the Rasch Analysis Model.

RESULTS

Fact-CAD scale was a reliable (high Person Separation Index of 0.89) and valid (unidimensional, no misfit, local independency supported, no residual correlations) measure of fear of activity. Three items showed differential item functioning according to employment status, marital status, and angina pectoris, which were not assigned as real item bias by experts and remained in the model.

CONCLUSION

Fact-CAD was supported by Rasch analysis as a psychometrically valid scale to evaluate fear of activity in patients with coronary artery disease.

Reliability and Validity of the Turkish Version of the Fremantle Back Awareness Questionnaire

STUDY DESIGN

Cross-cultural adaptation and psychometric analysis.

OBJECTIVE

To develop the Turkish version of the Fremantle Back Awareness Questionnaire (FreBAQ-T) and to evaluate its psychometric properties.

SUMMARY OF BACKGROUND DATA

There is a growing interest in the role that the disturbance of body perception may lead to long-lasting pain problems such as chronic low back pain (CLBP). The Fremantle Back Awareness Questionnaire (FreBAQ) is a simple and low-cost way of evaluating disturbed back awareness in people with CLBP.

METHODS

The FreBAQ was translated from English into Turkish using the forward-backward-forward method. One hundred four participants with low back pain completed the FreBAQ-T. The FreBAQ-T was repeated in 15 participants after 1 week to establish test-retest reliability. Although internal and external construct validity was investigated using Rasch analysis and Spearman correlation coefficient, respectively; reliability was evaluated in terms of internal consistency by Cronbach alpha and Person Separation Index.

RESULTS

All items of the FreBAQ-T were found to fit the Rasch Model (chi-square 6.17 [df = 9], P = 0.723). The internal construct validity was good, overall mean item fit residual was -0.305 (standard deviation: 0.369) and mean person fit residual was -0.290 (standard deviation: 1.349). The reliability was good with Cronbach alpha of 0.87 and Person Separation Index of 0.82. When the test-retest was examined via differential item functioning by time, none of the items showed differential item functioning.

CONCLUSION

The FreBAQ-T is a valid, reliable, and unidimensional scale for patients with CLBP. This scale will allow assessing back-specific perception in the Turkish population with CLBP.

Kinesiophobia as a Problem in Adherence to Physical Activity Recommendations in Elderly Polish Patients with Coronary Artery Disease

INTRODUCTION

The most commonly occurring diseases among the elderly people are cardiovascular system ones and among them the coronary artery disease (CAD). It is considered that the age and insufficient level of physical activity (PA) are the crucial risk factors of CAD. The key barrier which prevents elderly people from undertaking physical activity may be the fear of activity, called kinesiophobia.

AIM

The aim of this project was to examine the frequency of kinesiophobia among Polish elderly patients with CAD and its potential conditions: sex, age, CAD duration, other diseases and chosen socio-demographic variables.

REFERENCE AND METHODS

There have been 135 people examined: 59 women and 76 men in the 65-88 age range (average =71.88 years, SD=4.82). They were people diagnosed with stable CAD. The questionnaire form which was used collected information concerning the socio-demographical and physical activity data. And for kinesiophobia, there was Tampa Scale used, which is dedicated to examine cardiac patients - TSK heart.

RESULTS

Over 76% of examined patients had a high level of kinesiophobia (TSK>37 pt). Sex, age, BMI, CAD duration and the number of other diseases did not have any connection with neither PA nor TSK. Education was the only one, among the socio-demographic variables, which differentiated the kinesiophobia. Better educated people had a lower level of it.

CONCLUSION

Kinesiophobia is a common problem among the elderly people suffering from CAD. It is caused by a lack of physical activity which adversely predicts the progression of the disease. People with higher education are more rarely affected by kinesiophobia. CAD patients should be provided with knowledge and training concerning PA and there should be conditions created to enhance it.

Validation of the Tampa Scale for Kinesiophobia for Temporomandibular Disorders (TSK-TMD) in patients with painful TMD

Background

The aim of the study was to validation of the Tampa Scale for Kinesiophobia for Temporomandibular Disorders (TSK-TMD) for use in patients with painful TMD.

Methods

The original TSK-TMD was translated and cross-culturally adaptated following international guidelines. A total of 160 patients with temporomandibular disorders (TMD) were enrolled to fill out the scale. The internal consistency and test-retest methods were used to evaluate the reliability of the TSK-TMD. The validity of the TSK-TMD was analyzed by content validity, construct validity and convergent validity. Construct validity was assessed based on exploratory factor analysis (EFA), and convergent validity by examining the correlation between the global rating of oral health question and TSK-TMD scores.

Results

Cronbach’s alpha value for the total TSK-TMD score was 0.919 and the intraclass correlation coefficient (ICC) value for the TSK-TMD was 0.797. Construct validity was assessed by EFA, extracting two factors, accounting for 71.9% of the variance. The factor loadings of all items were higher than 0.40. In terms of convergent validity, the TSK-TMD subscales showed good correlations to the global rating of oral health question.

Conclusion

These findings show that the Chinese version of TSK-TMD has satisfactory psychometric properties and is appropriate for use in patients with painful TMD in China.
