Psychometric properties of the Pain Attitudes and Beliefs Scale for Physiotherapists: A systematic review

Is the use of diagnostic imaging and the self-reported clinical management of low back pain patients influenced by the attitudes and beliefs of chiropractors? A survey of chiropractors in the Netherlands and Belgium

BACKGROUND

No previous studies have examined the association between attitudes and beliefs of chiropractors and their adherence to low back pain (LBP) guidelines. The aim of this study is: (1) to assess the attitudes and beliefs towards the management of LBP of Dutch and Belgian chiropractors; and (2) to investigate the association of these attitudes and beliefs on the use of diagnostic imaging and on the adherence to diagnostic guidelines and guidelines in the management of patients with LBP.

METHODS

STUDY DESIGN: Cross-sectional study using a web-based questionnaire in chiropractic private practices in the Netherlands and Belgium. The survey included sociodemographic characteristics, use of diagnostic imaging, the Pain Attitude and Beliefs Scale-Physiotherapists (PABS.PT) and 6 vignettes (3 acute and 3 chronic LBP patients). We used Latent Profile Analysis (LPA) to categorise the chiropractors into clusters depending on their PABS.PT outcome, whereby the classes differed primarily on the biomedical score. We used linear, logistic, and mixed models to examine the associations between these clusters, and adherence to the recommendations of guidelines on: (1) diagnostic imaging use, and (2) management of LBP (i.e. advice on activity, treatment, return-to-work, and bedrest).

RESULTS

The response rate of the Dutch and Belgian chiropractors was 61% (n = 149/245) and 57% (n = 54/95), respectively. The majority of chiropractors scored midrange of the biomedical scale of the PABS.PT. Three clusters were identified using LPA: (1) high biomedical class (n = 18), (2) mid biomedical class (n = 117) and (3) low biomedical class (n = 23). Results from the vignettes suggest that chiropractors in the high biomedical class better adhere to diagnostic imaging guidelines and to LBP guidelines when it concerns advice on return-to-work and activity compared to the other two classes. However, no differences were identified between the classes for treatment of LBP. All chiropractors adhered to the guidelines' recommendation on bedrest.

CONCLUSION

The high biomedical class demonstrated better overall adherence to the practice guidelines for the management of LBP and diagnostic imaging than the other classes. Due to the small numbers for the high and low biomedical classes, these results should be interpreted with caution.

Comparing physical therapy students' attitudes and beliefs regarding chronic low back pain and knee osteoarthritis: an international multi-institutional comparison between 2013 and 2020 academic years

BACKGROUND

In 2013, physical therapy students demonstrated low guideline-adherent recommendations regarding chronic low back pain (CLBP) for spinal pathology, activity, and work.

OBJECTIVES

To assess the differences in physical therapy students' attitudes, beliefs, and adherence to guideline recommendations regarding CLBP and knee osteoarthritis between 2013 and 2020.

METHODS

In 2013 and 2020, second and fourth-year physical therapy students were recruited from 6 Belgian and 2 Dutch institutions. Attitudes and beliefs regarding CLBP and knee OA were evaluated using the Pain Attitudes and Beliefs Scale for Physiotherapists (PABS-PT), the Health Care Providers' Pain and Impairment Relationship Scale (HC-PAIRS), and a questionnaire regarding therapeutic exercise and knee osteoarthritis. A clinical vignette was used to measure guideline-adherent recommendations regarding spinal pathology, activity, and work.

RESULTS

In 2013, 927 second-year and 695 fourth-year students; in 2020, 695 second-year and 489 fourth-year students; were recruited to participate in the study. Compared to 2013, students had less biomedical and stronger biopsychosocial attitudes and beliefs regarding CLBP, more guideline-adherent recommendations for activity, and more biopsychosocial beliefs regarding the benefits of exercise for patients with knee osteoarthritis in both the second and fourth year. Only fourth-year students in 2020 scored significantly better on HC-PAIRS and guideline-adherent recommendation relating to spinal pathology. No differences were found regarding work recommendations.

CONCLUSIONS

Between 2013 and 2020, physical therapy students made a positive shift towards a more biopsychosocial approach to CLBP and knee osteoarthritis management. Guideline-adherent recommendations for CLBP concerning activity improved, however, concerning work and spinal pathology, it remained low.

Transcultural Adaptation and Psychometric Validation of the Spanish Version of the Pain Attitudes and Beliefs Scale for Physiotherapists

Low back pain (LBP) is one of the main musculoskeletal pain conditions, and it affects 23-28% of the global population. Strong evidence supports the absence of a direct relationship between the intensity of pain and tissue damage, with psychosocial factors also playing a crucial role. In this context, the Pain Attitudes and Beliefs Scale for Physiotherapists (PABS-PT) is a useful tool for evaluating physiotherapists' treatment orientations and beliefs regarding the management of low back pain (LBP). It helps identify practitioners who may benefit from additional education in modern pain neuroscience. However, there is not a Spanish validation of this scale for physiotherapists. Thus, the aims of this study were to translate and culturally adapt the Pain Attitudes and Beliefs Scale for Physiotherapists (PABS-PT) into Spanish and to evaluate its psychometric properties. This validation study used three convenience samples of physiotherapists (PTs) (n = 22 for the pilot study, n = 529 for the validity study and n = 53 for assessing the instrument's responsiveness). The process of translating and adapting the PABS-PT into Spanish followed international guidelines and produced a satisfactory pre-final version of the questionnaire. Factor analysis confirmed the two-factor structure of the original version, with the biomedical (BM) factor explaining 39.4% of the variance and the biopsychosocial (BPS) factor explaining 13.8% of the variance. Cronbach's alpha values were excellent for the BM factor (0.86) and good for the BPS factor (0.77), indicating good internal consistency. Test-retest reliability was excellent for both factors, with intraclass correlation coefficients (ICCs) of 0.84 for BM and 0.82 for BPS. The standard error of measurement (SEM) was acceptable for both factors (3.9 points for BM and 2.4 points for BPS). Concurrent validity was moderate and in the expected direction and had significant correlations with the Health Care Providers' Pain and Impairment Relationship Scale (HC-PAIRS) and Revised Neurophysiology Pain Questionnaire (R-NPQ). Sensitivity to change was demonstrated by significant improvements in both factors after an educational intervention, with medium-to-large effect sizes. The PABS-PT also showed good discriminative ability, as it was able to distinguish between physiotherapists with and without pain education. Cut-off values for the BM and BPS factors were determined. In conclusion, the translated and adapted Spanish version of the PABS-PT demonstrated good psychometric properties and can be reliably used to assess the attitudes and beliefs of Spanish-speaking physiotherapists regarding LBP. The questionnaire is recommended for use in clinical and educational research in the Spanish language context.

Teaching pain management to health professional students: A systematic review and meta-analysis

Background

Satisfactory pain management can have a significant impact on clients' activities of daily living. We questioned what types of pain management education might improve health professional students' knowledge, skills and perceptions?

Method

From inception until 30^th July 2020, we searched MEDLINE, EBM Reviews, CINAHL Plus, ERIC, EMBASE, Cochrane database and Monash University library. Inclusion criteria were controlled trials of health professional students' pain education compared to alternative education, usual curriculum or no intervention. Studies were limited to English. Data were synthesised using meta-analysis.

Results

Fourteen articles were included in this review. For continuous data, meta-analysis demonstrated a clear effect favouring the intervention for knowledge SMD 1.47 [95% CI 1.18, 1.77], skills 0.93 [0.58, 1.28] or perceptions 0.69 [0.31, 1.08]. For dichotomous data, results showed no effect for knowledge 4.21 [0.65, 27.41], skills 2.26 [0.47, 11.01] or perceptions 1.96 [0.66, 5.76]. However, the overall result showed an effect 2.82 [1.20, 6.59] favouring the intervention.

Conclusions

In summary, short theoretical interventions are sufficient to change students' knowledge and perceptions. Longer interventions incorporating interactivity improve skills. Further research is required to indicate the best method, outcome measure, length of intervention and follow-up in delivering these pain courses and assessing the cost and long-term retention of information.

Comparison of attitudes and beliefs of physical therapists and primary care physicians regarding low back pain management: A cross-sectional study

BACKGROUND

The first-line contact for patients seeking care for low back pain (LBP) can potentially change the disease course. The beliefs and attitudes of healthcare providers (HCPs) can influence LBP management. Although referring patients with LBP to physical therapy is common, the first-line contact for patients with LBP in Saudi Arabia is the primary care physician (PCP). Physical therapy will soon be integrated into primary care; therefore, it is rational to compare physical therapists' (PTs) beliefs and attitudes regarding LBP with those of PCPs.

OBJECTIVE

We compared PCPs' and PTs' attitudes and beliefs regarding LBP management.

METHODS

We employed a cross-sectional, voluntary response sample research design using the Pain Attitudes and Beliefs Scale (PABS). Participants were PTs and PCPs practicing in Saudi Arabia.

RESULTS

In total, 153 participants completed the PABS (111 PTs and 52 PCPs). PCPs demonstrated significantly higher PABS biomedical subscale scores than did the PTs.

CONCLUSIONS

HCPs in Saudi Arabia should receive additional training to adopt a biopsychosocial approach to managing LBP. In this study, the HCPs' treatment recommendations may not correspond with contemporary clinical guidelines. Research to facilitate the implementation of optimal professional education and training to adopt a biopsychosocial approach is an urgent priority.

Pain Neurophysiology Knowledge Enhances Attitudes toward Biopsychosocial Management of Low Back Pain among Japanese Physical Therapists

Objectives:

The aim of the current study was to investigate whether a postgraduate academic degree, longer clinical experience, and pain neurophysiology knowledge influence attitudes toward the balance between biomedical and biopsychosocial management of low back pain (LBP).

Methods:

Ninety Japanese physical therapists completed the revised Neurophysiology of Pain Questionnaire (revised NPQ), the Pain Attitudes and Beliefs Scale for Physiotherapists (PABS-PT) questionnaire, and a survey on their degree qualifications and clinical experience. Their attitudes toward the balance between biomedical and biopsychosocial management of LBP were assessed using the mean biomedical scale scores divided by the mean biopsychosocial scale scores of the PABS-PT. Multiple regression modeling of the attitudes toward the balance between biomedical and biopsychosocial management of LBP was carried out using three independent variables: possession of an undergraduate or postgraduate academic degree, length of clinical experience, and the score on the revised NPQ.

Results:

Of the 90 therapists, 72 had an undergraduate degree and 18 also had a postgraduate degree. Only the revised NPQ score (β=−0.364, P <0.001) was a statistically significant contributing factor to attitudes toward the balance between biomedical and biopsychosocial management of LBP (R²=0.14). Neither having a postgraduate degree (β=0.017, P=0.871) nor the length of clinical experience (β=−0.107, P=0.303) had a significant effect.

Conclusions:

This study demonstrated that pain neurophysiology knowledge, but not the possession of a postgraduate academic degree or the length of clinical experience, promotes attitudes toward biopsychosocial management of LBP among Japanese physical therapists.

Effects of an e-learning programme on osteopaths' back pain attitudes: a mixed methods feasibility study

BACKGROUND

The biopsychosocial model is recommended in the management of non-specific low back pain but musculoskeletal practitioners can lack skills in assessing and managing patients using a biopsychosocial framework. Educational interventions have produced equivocal results. There is a need for an alternative educational tool to support practitioners' development in the application of biopsychosocial model to manage low back pain.

METHODS

A mixed methods study assessed the feasibility and acceptability of an e-learning programme on the biopsychosocial management of non-specific low back pain for osteopaths with more than 15 years' experience. A sequential explanatory design was conducted, with a feasibility randomised controlled trial and semi-structured interviews explored with thematic analysis.

RESULTS

A total of 45 participants participated in the RCT of which 9 also participated in the interview study. The a-priori sample size was not met (45 instead of 50). The recruitment strategies, randomisation, retention, data collection and outcome measures worked well and were found to be feasible for a main trial. The retention, satisfaction and participants' views of the programme demonstrated a good acceptability of the programme. Data from the semi-structured interviews were organised in three themes, the first two were related to the feasibility and acceptability of the e-learning programme (practical experience of following the course and engagement with the content) and the third relates to the impact of the intervention (perception of the BPS model).

CONCLUSION

A main RCT is feasible and the intervention was received well by the participants. A main RCT is required to assess the effectiveness of the e-learning programme. This work also provided data on aspects so far unreported, including osteopaths' views on continuing professional development, on e-learning as a form of continuing professional development and osteopaths' perceptions and challenges concerning the implementation of the biopsychosocial model in practice.

Patient- and Physical Therapist-Level Predictors of Patient-Reported Therapeutic Alliance: An Observational, Exploratory Study of Cohorts With Knee and Low Back Pain

OBJECTIVE

To identify patient- and physical therapist-level predictors for therapeutic alliance at the end of an episode of physical therapy for knee or low back pain (LBP).

DESIGN

Secondary analysis of observational cohort.

SETTING

Outpatient physical therapy clinics.

PARTICIPANTS

Patients receiving physical therapy for knee (n=189) or LBP (n=252) and physical therapists (n=19). Candidate predictor variables included demographics, patient clinical characteristics, and physical therapist attitudes and beliefs (Pain Attitudes and Beliefs Scale for Physical Therapists) and confidence in providing patient-centered care (Self-Efficacy in Patient-Centeredness Questionnaire).

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

Patient-reported therapeutic alliance was measured using the 12-item Work Alliance Inventory-Short Revised (WAI-SR).

RESULTS

Final linear mixed models indicated different patient- and physical therapist-level factor contributions in predicting final WAI-SR scores across cohorts with knee and LBP. Female sex was a consistent patient-level predictor for both knee (estimated β=1.57, P<.05) and LBP (β=1.42, P<.05), with age (β=-0.07, P<.01) and baseline function (β=0.06, P<.01) contributing to cohorts with knee and LBP, respectively. Physical therapist-level predictors included female sex (β=6.04, P<.05), Pain Attitudes and Beliefs Scale for Physiotherapists behavioral (β=0.65, P<.01), and Self-Efficacy in Patient-Centeredness Questionnaire (SEPCQ) Exploring Patient Perspective (β=-0.75, P<.01) subscale scores for LBP, with SEPCQ Sharing Information and Power subscale scores (β=0.56, P<.05) contributing to both cohorts with knee (β=0.56, P<.05) and LBP (β=0.74, P<.01). Random effects for patients nested within physical therapists were observed for both cohorts.

CONCLUSIONS

These findings provide preliminary evidence for inconsistent relationships among patient- and physical therapist-level factors and therapeutic alliance across cohorts with knee and LBP.

Knowledge and attitudes toward musculoskeletal pain neuroscience of manual therapy postgraduate students in the Netherlands

BACKGROUND

Health care practitioners' knowledge and attitudes influence patients' beliefs and health outcomes in musculoskeletal (MSK) pain. It is unclear to what extent physiotherapists undertaking a postgraduate master in manual therapy (MT students) possess the knowledge and attitudes toward pain neuroscience to be able to apply the biopsychosocial model in patients with MSK pain.

OBJECTIVES

The aim of this study was to assess the knowledge and attitudes toward pain neuroscience in MT students.

DESIGN

A cross-sectional study.

METHOD

Self-reported knowledge and attitudes were measured among students (n = 662) at baseline and in all years of the MT postgraduate programs in the Netherlands. The Knowledge and Attitudes of Pain questionnaire (KNAP) was used as a primary measure. Difference in KNAP-scores between baseline (0), year 1, year 2 and year 3 was tested using a one-way ANOVA (hypothesis: 0 < 1<2 < 3). A two factor ANOVA was used to determine the interaction effect of focused pain education and year in the curriculum with KNAP.

RESULTS

There was an overall significant difference of KNAP scores with a medium effect size (F(3, 218.18) = 13.56, p < .001, ω² = 0.059). Differences between years ranged from small to medium. Interaction effect of knowledge and attitudes and focused pain education was significant with a small effect size (F(6) = 2.597, p = .017, ω² = 0.012). Sensitivity analyses were consistent with the main results.

CONCLUSIONS

Positive differences in knowledge and attitudes toward pain neuroscience in MT students occur between the progressing years of the curriculum. Differences may be related to the provision of focused pain education.

Augmented behavioral medicine competencies in physical therapy students' clinical reasoning with a targeted curriculum: a final-semester cohort-comparison study

Background: Knowledge regarding the impact of curricula with behavioral medicine content and competencies (BMCC) on physical therapy (PT) students' clinical reasoning skills is lacking. Objectives: The primary objective was to compare the clinical reasoning skills, focusing on clients' behavioral change, of entry-level PT students with or without BMCC in their curricula. The secondary objective was to compare students' attitudes and beliefs in a biomedical and biopsychosocial practice orientation.Methods: Swedish final-semester PT students (n = 151) completed the Reasoning 4 Change (R4C) instrument and the Pain Attitudes and Beliefs Scale for Physiotherapists. A blueprint was used for curricular categorization. The independent t-test was used.Results: Students attending programs with BMCC curricula (n = 61) had superior scores compared with students without BMCC curricula (n = 90) in the following R4C variables, all of which were related to clinical reasoning focused on behavioral change: Knowledge, Cognition, Self-efficacy, Input from the client, Functional behavioral analysis, and Strategies for behavioral change. Students who did not receive BMCC curricula scored higher in the R4C contextual factors and reported a greater biomedical practice orientation than students receiving BMCC curricula. There was no difference in the biopsychosocial practice orientation between groups.Conclusions: Our findings support the benefit of structured entry-level PT curricula with BMCC on final-semester students' clinical reasoning skills focused on behavioral change and their level of biomedical practice orientation. Further, our findings elucidated educational opportunities to augment students' self-efficacy and strengthen their behavioral competencies in clinical reasoning. For the generalizability of the results further research in other contexts is needed.

Communication skills in the context of psychological flexibility: training is associated with changes in responses to chronic pain in physiotherapy students in Spain

Introduction

The aim of this study is to explore the effectiveness of a training programme aimed at managing patients' chronic pain in physiotherapy students in Spain. The programme addressed providing them with efficient skills to manage patients' chronic pain from psychological flexibility (PF) perspective.

Methods

The programme integrates communication skills training into PF-based training. It sought to contribute to better recognise the role of psychosocial factors in chronic pain and to better promote adherence to treatment. This is an observational study with a pre- and post-training programme design and a 2-month follow-up. A total of 35 physiotherapy students, divided into three groups, participated in a 10-hour training course. Training focused on three areas: (1) communication skills, (2) therapeutic adherence and (3) managing distress and pain. The three areas were addressed from the PF point of view. Impact of training was measured through standardised questionnaires that assessed attitudes towards chronic pain, an ad hoc questionnaire that assessed responses to difficult communicative situations and a training satisfaction scale.

Results

Final analyses showed that attitudes changed significantly after training, biomedical attitude scores decreased and biopsychosocial attitude increased, while pain was considered less disabling, and informed empathic responses in communication situations increased. These changes were maintained at 2-month follow-up. Satisfaction with the training was high.

Conclusion

We conclude that a brief training programme based on the PF model may help students develop a more comprehensive approach and improve their skills for managing chronic pain.

Assessing future health care practitioners' knowledge and attitudes of musculoskeletal pain; development and measurement properties of a new questionnaire

BACKGROUND

Healthcare practitioner beliefs influence patients' beliefs and health outcomes in musculoskeletal (MSK) pain. A validated questionnaire based on modern pain neuroscience assessing Knowledge and Attitudes of Pain (KNAP) was unavailable.

OBJECTIVES

The aim of this study was to develop and test measurement properties of KNAP.

DESIGN

Phase 1; Development of KNAP reflecting modern pain neuroscience and expert opinion. Phase 2; a cross-sectional and longitudinal study among Dutch physiotherapy students.

METHOD

In the cross-sectional study (n = 424), internal consistency, structural validity, hypotheses testing, and Rasch analysis were examined. Longitudinal designs were applied to analyse test-retest reliability (n = 156), responsiveness, and interpretability (n = 76).

RESULTS

A 30-item KNAP was developed in 4 stages. Test-retest reliability: ICC (2,1) 0.80. Internal consistency: Cronbach's α 0.80. Smallest Detectable Difference 90%: 4.99 (4.31; 5.75). Structural validity: exploratory factor analysis showed 2 factors. Hypotheses testing: associations with the Pain Attitudes and Beliefs Scale for Physiotherapists biopsychosocial subscale r = 0.60, with biomedical subscale r = -0.58, with the Neurophysiology of Pain Questionnaire r = 0.52. Responsiveness: 93% improved on KNAP after studying pain education. Minimal Important Change: 4.84 (95%CI: 2.77; 6.91).

CONCLUSIONS

The KNAP has adequate measurement properties. This new questionnaire could be useful to evaluate physiotherapy students' knowledge and attitudes of modern pain neuroscience that could help to create awareness and evaluate physiotherapy education programs, and ultimately provide better pain management.

Pain knowledge, attitudes and beliefs of Australian osteopaths drawn from a nationally representative sample of the profession

BACKGROUND

Pain has been identified as a global health issue with substantial effects on individuals and society. Health professionals managing pain complaints must have appropriate knowledge of pain neurophysiology, and attitudes and beliefs towards pain management that align with current practice guidelines.

OBJECTIVES

Evaluate Australian osteopaths' current level of knowledge of pain neurophysiology and their beliefs and attitudes towards pain, and explore associations with demographic variables.

METHOD

Australian osteopaths drawn from a nationally representative practice-based research network received the questionnaire. The questionnaire included demographic information, Neurophysiology of Pain Questionnaire (NPQ), Pain Attitudes and Beliefs Scale for Physiotherapists (PABS-PT) and the Attitudes to Back Pain Scale in Musculoskeletal Practitioners (ABS-mp).

RESULTS

Complete responses were received from 211 osteopaths (21.3% response rate). The mean total NPQ score was equivalent to 72.2% correct responses. The PABS-PT Biomedical scale mean score was 38.8 ( ±9.1, α = 0.81) and the Biopsychosocial scale was 22.3 ( ±3.3, α = 0.38). ABS-mp mean factor scores suggest osteopaths support psychological approaches (22.1, ±3.3, α = 0.71) but endorsed more treatment sessions for those with back pain (15.9, ±4.7, α = 0.71). Trivial correlations between measures and most demographic variables were observed. Osteopaths who undertook further studies in pain had higher mean NPQ scores, with moderate negative correlations with a lower PABS-PT Biomedical subscale score (ρ = -0.45, p < 0.01).

CONCLUSIONS

Australian osteopaths demonstrate a range of pain neurophysiology knowledge, and beliefs and attitudes towards pain. The findings support the positive impact of professional development for improving pain knowledge in this population.

How do physiotherapists understand and interpret the "Pain Attitudes and Beliefs Scale"? A cognitive interview study

Background: The Pain Attitudes and Beliefs Scale (PABS) for physiotherapists aims to differentiate between clinicians' biomedical and biopsychosocial treatment orientations regarding nonspecific low back pain (LBP). Objective: To study the content validity of the Norwegian PABS by following international guidelines: exploring its relevance, comprehensibility and comprehensiveness. Methods: Cognitive interviews were performed using the Three-Step Test Interview, consisting of think-aloud techniques, retrospective probing and in-depth interviews. Eleven Norwegian physiotherapists with a diversity of professional backgrounds participated. Results: The participants encountered little difficulty in completing the PABS. All items were deemed relevant and important but five items had ambiguous formulations which can easily be handled. The biomedical subscale appeared to be a comprehensive representation of biomedical treatment orientation. The biopsychosocial subscale was found to lack items concerning cognitive behavioral aspects of LBP management, such as patient education, therapeutic alliance, shared decision making and graded exposure. Conclusions: This study provides empirical evidence that the Norwegian version of the PABS-PT is relevant and comprehensible, provided some minor adjustments. The biopsychosocial subscale, however, lacks comprehensiveness, as it is not able to capture important aspects of contemporary biopsychosocial best practice care. Measurement of biopsychosocial treatment orientation may therefore be incomplete.

Confidence, attitudes, beliefs and determinants of implementation behaviours among physiotherapists towards clinical management of low back pain before and after implementation of the BetterBack model of care

BACKGROUND

Implementing clinical guidelines is challenging. To facilitate uptake, we developed a model of care (BetterBack Model of Care) and an implementation strategy to support management of low back pain in primary care. The aim of this study was to evaluate physiotherapists´ confidence, attitudes and beliefs in managing patients with low back pain before and after a multifaceted implementation of the BetterBack Model of Care. A further aim was to evaluate determinants of implementation behaviours among physiotherapists.

METHODS

This clinical trial was an experimental before and after study within a hybrid type 2 effectiveness-implementation trial. The primary outcome was Practitioner Self-Confidence Scale (PCS), secondary outcomes were the Pain Attitude and Beliefs Scale for Physiotherapists (PABS-PT) and Determinants of Implementation Behaviour Questionnaire (DIBQ). Data was analysed using repeated measures ANOVA and pairwise comparisons.

RESULTS

One hundred sixteen physiotherapists answered a questionnaire before, directly after, as well as 3 and 12 months after implementation of the Model of Care. PCS improved over time with a large effect size post implementation (ηp2 = 0.197, p < 0.001). Changes in PABS-PT were only significant after 12 months with higher biopsychosocial orientation, (ηp2 = 0.071, p < 0.01) and lower biomedical orientation, (ηp2 = 0.136, p < 0.001). Directly after the workshop, after 3 and 12 months, physiotherapists had high ratings on all DIBQ domains, (scores > 50) implying that all were potential facilitators of the implementation. However, after 3 months, all domains had significantly decreased except for organisation, social influence and patient expectation domains. However, after 12 months, organisation and social influence domains had significantly decreased while domains such as knowledge, skills and beliefs about capabilities returned to initial levels.

CONCLUSIONS

Physiotherapists´ confidence and biopsychosocial orientation increased after implementation and may have the potential to improve management of low back pain in primary care. The implementation behaviour showed mostly facilitating patterns but changed over time, pinpointing a need to repeatedly monitor these changes. This can inform the need for changes of implementation efforts in different phases and support sustainability strategies.

Can the Pain Attitudes and Beliefs Scales be adapted for use in the context of osteoarthritis with general practitioners and physiotherapists?

BACKGROUND

Conservative, first-line treatments (exercise, education and weight-loss if appropriate) for hip and knee joint osteoarthritis are underused despite the known benefits. Clinicians' beliefs can affect the advice and education given to patients, in turn, this can influence the uptake of treatment. In New Zealand, most conservative OA management is prescribed by general practitioners (GPs; primary care physicians) and physiotherapists. Few questionnaires have been designed to measure GPs' and physiotherapists' osteoarthritis-related health, illness and treatment beliefs. This study aimed to identify if a questionnaire about low back pain beliefs, the Pain Attitudes and Beliefs Scale for Physiotherapists (PABS-PT), can be adapted to assess GP and physiotherapists' beliefs about osteoarthritis.

METHODS

This study used a cross-sectional observational design. Data were collected anonymously from GPs and physiotherapists using an online survey. The survey included a study-specific demographic and occupational characteristics questionnaire and the PABS-PT questionnaire adapted for osteoarthritis. All data were analysed using descriptive statistics, and the PABS-PT data underwent principal factor analysis.

RESULTS

In total, 295 clinicians (87 GPs, 208 physiotherapists) participated in this study. The principal factor analysis identified two factors or subscales (categorised as biomedical and behavioural), with a Cronbach's alpha of 0.84 and 0.44, respectively.

CONCLUSIONS

The biomedical subscale of the PABS-PT appears appropriate for adaptation for use in the context of osteoarthritis, but the low internal consistency of the behavioural subscale suggests this subscale is not currently suitable. Future research should consider the inclusion of additional items to the behavioural subscale to improve internal consistency or look to develop a new, osteoarthritis-specific questionnaire.

TRIAL REGISTRATION

This trial was part of the primary author's PhD, which began in 2012 and therefore this study was not registered.

Evaluation of pain knowledge and attitudes and beliefs from a pre-licensure physical therapy curriculum and a stand-alone pain elective

BACKGROUND

Adequate pain education of health professionals is fundamental in the management of pain. Although an interprofessional consensus of core competencies for health professional pre-licensure education in pain have been established, the degree of their incorporation into physical therapy curriculum varies greatly. The purpose of this study was to 1. Assess students' pain knowledge and their attitudes and beliefs in a pre-licensure physical therapy curriculum using a cross sectional comparison, and 2. Using a sub-sample of this population, we evaluated if an elective course on pain based on International Association for the Study of Pain (IASP) guidelines had an effect on students' knowledge and beliefs.

METHODS

The Neurophysiology of Pain Questionnaire (NPQ) and the Pain Attitudes and Beliefs Scale for Physiotherapists (PABS-PT) was completed by first semester (n = 72) and final (n = 56) semester doctor of physical therapy (DPT) students. Final semester students completed surveys before and after participation in an elective course of their choosing (pain elective (PE) or other electives (OE)).

RESULTS

Participation rate was > 90% (n = 128/140). We found mean differences in NPQ scores between final semester (3rd year) students (76.9%) compared to first semester students (64%), p < 0.001. Third year students showed a mean difference on PABS-PT subscales, showing decreased biomedical (p < 0.001) and increased biopsychosocial (p = 0.005) scores compared to first semester students. Only final semester students that participated in the PE improved their NPQ scores (from 79 to 86%, p < 0.001) and demonstrated a significant change in the expected direction on PABS-PT subscales with increased biopsychosocial (p = 0.003) and decreased biological scores (p < 0.001).

CONCLUSIONS

We suggest that although core pre-licensure DPT education improves students' pain knowledge and changes their attitudes towards pain, taking a IASP based pain elective continues to improve their pain neurobiology knowledge and also further changes their attitudes and beliefs towards pain. Therefore, a stand-alone course on pain in addition to pain concepts threaded throughout the curriculum may help ensure that entry-level DPT students are better prepared to effectively work with patients with pain.

Confidence and Attitudes Toward Osteoarthritis Care Among the Current and Emerging Health Workforce: A Multinational Interprofessional Study

Objective

To measure confidence and attitudes of the current and emerging interprofessional workforce concerning osteoarthritis (OA) care.

Methods

Study design is a multinational (Australia, New Zealand, Canada) cross-sectional survey of clinicians (general practitioners [GPs], GP registrars, primary care nurses, and physiotherapists) and final-year medical and physiotherapy students. GPs and GP registrars were only sampled in Australia/New Zealand and Australia, respectively. The study outcomes are as follows: confidence in OA knowledge and skills (customized instrument), biomedical attitudes to care (Pain Attitudes Beliefs Scale [PABS]), attitudes toward high- and low-value care (customized items), attitudes toward exercise/physical activity (free-text responses).

Results

A total of 1886 clinicians and 1161 students responded. Although a number of interprofessional differences were identified, confidence in OA knowledge and skills was consistently greatest among physiotherapists and lowest among nurses (eg, the mean difference [95% confidence interval (CI)] for physiotherapist-nurse analyses were 9.3 [7.7-10.9] for knowledge [scale: 11-55] and 14.6 [12.3-17.0] for skills [scale: 16-80]). Similarly, biomedical attitudes were stronger in nurses compared with physiotherapists (6.9 [5.3-8.4]; scale 10-60) and in medical students compared with physiotherapy students (2.0 [1.3-2.7]). Some clinicians and students agreed that people with OA will ultimately require total joint replacement (7%-19% and 19%-22%, respectively), that arthroscopy is an appropriate intervention for knee OA (18%-36% and 35%-44%), and that magnetic resonance imaging is informative for diagnosis and clinical management of hip/knee OA (8%-61% and 21%-52%). Most agreed (90%-98% and 92%-97%) that exercise is indicated and strongly supported by qualitative data.

Conclusion

Workforce capacity building that de-emphasizes biomedical management and promotes high-value first-line care options is needed. Knowledge and skills among physiotherapists support leadership roles in OA care for this discipline.

Targeted interventions to prevent transitioning from acute to chronic low back pain in high-risk patients: development and delivery of a pragmatic training course of psychologically informed physical therapy for the TARGET trial

Background

Low back pain (LBP) is a public health concern because it is highly prevalent and the leading cause of disability worldwide. Psychologically informed physical therapy (PIPT) is a secondary prevention approach that first aims to identify individuals at high risk for transitioning to chronicity and then provides tailored treatment to reduce that risk. Training models that are feasible to implement with acceptable training quality are needed to improve scalability for widespread implementation of PIPT. This manuscript describes the PIPT training program that was developed for training physical therapists providing PIPT in the TARGET trial.

Methods

The PIPT training program was developed, tested, and modified using an iterative process. Content development consisted of stakeholder engagement, beta testing, modification of training, and confirmation of final course objectives. Methods of delivery consisted of a website that included brief online educational modules followed by a live 8-h workshop that included video-based mock case scenarios and case-based role playing. Attitudes, beliefs, and confidence in implementing PIPT principles were assessed before and immediately after training to measure training quality and impact.

Results

Early stakeholder engagement and beta testing indicated the need for increased emphasis on experiential learning opportunities and patient-centered communication training. Booster training varied extensively across TARGET sites with involvement of ‘clinician champions’ providing brief follow-up sessions identified as best practice. Favorable post-training changes in physical therapist attitudes and beliefs toward biopsychosocial treatment orientation and increased confidence in implementing PIPT principles were observed.

Conclusions

PIPT training for provider participation in the TARGET trial was feasible to deliver. Course content was acceptable to physical therapists and resulted in improved beliefs and confidence in applying PIPT skills during clinical practice. Ongoing consultation and site-based continuing education were methods by which specific TARGET sites maintained or augmented PIPT skill training; however, implementing ongoing training was challenging in general. Due to the pragmatic nature of the TARGET trial, it was not possible to directly measure the effect of PIPT training on treatment fidelity, which was a limitation of our approach.

Discriminative Validity of the Pain Attitudes and Beliefs Scale for Physical Therapists

BACKGROUND

The Pain Attitudes and Beliefs Scale (PABS) for Physical Therapists aims to measure clinicians' biomedical and biopsychosocial treatment orientations regarding nonspecific low back pain.

OBJECTIVE

The objective of this study was to assess whether the PABS can differentiate between subgroups of physical therapists hypothesized to differ in treatment orientations.

DESIGN

This study was a cross-sectional survey.

METHODS

The PABS was completed by 662 Norwegian physical therapists with a diversity of professional backgrounds. Twenty-four a priori hypotheses on expected differences in PABS scores were formulated. Sufficient discriminative ability was defined as a minimum of 75% confirmed hypotheses. Hypotheses on differences in scores were tested for the biomedical and biopsychosocial subscales separately as well as for combinations of the 2 subscales, representing responders with high biomedical and low biopsychosocial PABS scores and vice versa.

RESULTS

Of the 24 hypotheses, only 15 (62.5%) were confirmed. Between-group differences concerning the separate subscales were small, varying from -0.63 to 1.70 scale points, representing values up to 6.0% of the total subscale ranges. Between-group differences were larger when combined subscales were used, varying from 1.80 to 6.70 points, representing values up to 25.1% of the total subscale ranges. Despite little spread in scores, 24% of respondents demonstrated extreme attitudes.

LIMITATIONS

The lack of convincing scientific evidence from previous research on differences in attitudes and beliefs between physical therapists was a limitation for the formulation of hypotheses.

CONCLUSIONS

Discriminative validity of separate subscales of the PABS was not supported. Combining the 2 subscales into global treatment attitudes enabled better discrimination. Little spread in biomedical and biopsychosocial orientations explains why more than one-third of the hypotheses were not confirmed. Either Norwegian physical therapists are basically similar in their treatment orientation or the PABS is not able to detect any differences between them.

Translation and psychometric evaluation of the Hebrew version of the Health Care Providers' Pain and Impairment Relationship Scale

BACKGROUND AND PURPOSE

Physiotherapists' different attitudes towards low back pain (LBP) are associated with patients' attitudes towards pain and with patients' disability. The Health Care Providers' Pain and Impairment Relationship Scale (HC-Pairs) is a self-administered instrument that assesses the attitudes and beliefs of health care professionals regarding LBP and the patient's daily function. The aims of this study are to translate, culturally adapt, and asses the psychometric properties of the Hebrew version of the HC-Pairs.

METHODS

The English version of the HC-Pairs was forward-backward translated, pretested, and reviewed by a panel of experts. Reliability was determined by computing Cronbach's α, and validity by exploring the correlations between the HC-Pairs' scores and the Pain Attitudes and Beliefs Scale for Physiotherapists (PABS-PT) scores. Confirmatory factor analysis was performed. A convenience sample of 277 physiotherapists was invited to fill the HC-Pairs and PABS-PT questionnaires and a sociodemographic questionnaire.

RESULTS

The forward-backward translation process revealed minor discrepancies between the texts. After the pretest, the expert panel agreed on a final version. A sample of 241 physiotherapists completed the questionnaires (response rate of 87%; 241/277); 213 met the inclusion criteria. Factor analysis suggests that the Hebrew version of the scale fits the one-factor model. Cronbach's α was 0.81 after deletion of two items and indicated good internal consistency. The scores produced by the instrument showed a substantial correlation with those of the biomedical dimension of the PABS-PT, and poor correlation with the behavioural dimension, in the expected directions.

CONCLUSION

The findings of the present study on the psychometric properties of the HC-Pairs are positive. Nevertheless, the Hebrew version of the HC-Pairs is still in a developmental stage. Further psychometric research is needed to assess the attitudes and beliefs of Hebrew-speaking physiotherapists, which have been shown to be associated with treatment orientations and work recommendations.

Item response theory evaluation of the biomedical scale of the Pain Attitudes and Beliefs Scale

OBJECTIVES

The assessment of health care professionals' attitudes and beliefs towards musculoskeletal pain is essential because they are key determinants of their clinical practice behaviour. The Pain Attitudes and Beliefs Scale (PABS) biomedical scale evaluates the degree of health professionals' biomedical orientation towards musculoskeletal pain and was never assessed using item response theory (IRT). This study aimed at assessing the psychometric performance of the 10-item biomedical scale of the PABS scale using IRT.

METHODS

Two cross-sectional samples (BeBack, n = 1016; DABS; n = 958) of health care professionals working in the UK were analysed. Mokken scale analysis (nonparametric IRT) and common factor analysis were used to assess dimensionality of the instrument. Parametric IRT was used to assess model fit, item parameters, and local reliability (measurement precision).

RESULTS

Results were largely similar in the two samples and the scale was found to be unidimensional. The graded response model showed adequate fit, covering a broad range of the measured construct in terms of item difficulty. Item 3 showed some misfit but only in the DABS sample. Some items (i.e. 7, 8 and 9) displayed remarkably higher discrimination parameters than others (4, 5 and 10). The scale showed satisfactory measurement precision (reliability > 0.70) between theta values -2 and +3.

DISCUSSION

The 10-item biomedical scale of the PABS displayed adequate psychometric performance in two large samples of health care professionals, and it is suggested to assess group-level professionals degree of biomedical orientation towards musculoskeletal pain.

Promoting the use of self-management in novice chiropractors treating individuals with spine pain: the design of a theory-based knowledge translation intervention

Background

Clinical practice guidelines generally recommend clinicians use self-management support (SMS) when managing patients with spine pain. However, even within the educational setting, the implementation of SMS remains suboptimal. The objectives of this study were to 1) estimate the organizational readiness for change toward using SMS at the Canadian Memorial Chiropractic College (CMCC), Toronto, Ontario from the perspective of directors and deans, 2) estimate the attitudes and self-reported behaviours towards using evidence-based practice (EBP), and beliefs about pain management among supervisory clinicians and chiropractic interns, 3) identify potential barriers and enablers to using SMS, and 4) design a theory-based tailored Knowledge Translation (KT) intervention to increase the use of SMS.

Methods

Mixed method design. We administered three self-administered questionnaires to assess clinicians’ and interns’ attitudes and behaviours toward EBP, beliefs about pain management, and practice style. In addition, we conducted 3 focus groups with clinicians and interns based on the Theoretical Domain Framework (TDF) to explore their beliefs about using SMS for patients with spine pain. Data were analysed using deductive thematic analysis by 2 independent assessors. A panel of 7 experts mapped behaviour change techniques to key barriers identified informing the design of a KT intervention.

Results

Participants showed high level of EBP knowledge, positive attitude of EBP, and moderate frequency of EBP use. A number of barrier factors were identified from clinicians (N = 6) and interns (N = 16) corresponding to 7 TDF domains: Knowledge; Skills; Environmental context and resources; Emotion; Beliefs about Capabilities; Memory, attention & decision making; and Social Influence. To address these barriers, the expert panel proposed a multifaceted KT intervention composed of a webinar and online educational module on a SMS guided by the Brief Action Planning, clinical vignettes, training workshop, and opinion leader support.

Conclusion

SMS strategies can help maximizing the health care services for patients with spine pain. This may in turn optimize patients’ health. The proposed theory-based KT intervention may facilitate the implementation of SMS among clinicians and interns.

Criterion scores, construct validity and reliability of a web-based instrument to assess physiotherapists' clinical reasoning focused on behaviour change: 'Reasoning 4 Change'

Background and aim: 'Reasoning 4 Change' (R4C) is a newly developed instrument, including four domains (D1-D4), to assess clinical practitioners' and students' clinical reasoning with a focus on clients' behaviour change in a physiotherapy context. To establish its use in education and research, its psychometric properties needed to be evaluated. The aim of the study was to generate criterion scores and evaluate the reliability and construct validity of a web-based version of the R4C instrument. Methods: Fourteen physiotherapy experts and 39 final-year physiotherapy students completed the R4C instrument and the Pain Attitudes and Beliefs Scale for Physiotherapists (PABS-PT). Twelve experts and 17 students completed the R4C instrument on a second occasion. The R4C instrument was evaluated with regard to: internal consistency (five subscales of D1); test-retest reliability (D1-D4); inter-rater reliability (D2-D4); and construct validity in terms of convergent validity (D1.4, D2, D4). Criterion scores were generated based on the experts' responses to identify the scores of qualified practitioners' clinical reasoning abilities. Results: For the expert and student samples, the analyses demonstrated satisfactory internal consistency (α range: 0.67-0.91), satisfactory test-retest reliability (ICC range: 0.46-0.94) except for D3 for the experts and D4 for the students. The inter-rater reliability demonstrated excellent agreement within the expert group (ICC range: 0.94-1.0). The correlations between the R4C instrument and PABS-PT (r range: 0.06-0.76) supported acceptable construct validity. Conclusions: The web-based R4C instrument shows satisfactory psychometric properties and could be useful in education and research. The use of the instrument may contribute to a deeper understanding of physiotherapists' and students' clinical reasoning, valuable for curriculum development and improvements of competencies in clinical reasoning related to clients' behavioural change.

Effectiveness of implementing a best practice primary healthcare model for low back pain (BetterBack) compared with current routine care in the Swedish context: an internal pilot study informed protocol for an effectiveness-implementation hybrid type 2 trial

INTRODUCTION

Low back pain (LBP) is a major health problem commonly requiring healthcare. In Sweden, there is a call from healthcare practitioners (HCPs) for the development, implementation and evaluation of a best practice primary healthcare model for LBP.

AIMS

(1) To improve and understand the mechanisms underlying changes in HCP confidence, attitudes and beliefs for providing best practice coherent primary healthcare for patients with LBP; (2) to improve and understand the mechanisms underlying illness beliefs, self-care enablement, pain, disability and quality of life in patients with LBP; and (3) to evaluate a multifaceted and sustained implementation strategy and the cost-effectiveness of the BetterBack☺ model of care (MOC) for LBP from the perspective of the Swedish primary healthcare context.

METHODS

This study is an effectiveness-implementation hybrid type 2 trial testing the hypothesised superiority of the BetterBack☺ MOC compared with current routine care. The trial involves simultaneous testing of MOC effects at the HCP, patient and implementation process levels. This involves a prospective cohort study investigating implementation at the HCP level and a patient-blinded, pragmatic, cluster, randomised controlled trial with longitudinal follow-up at 3, 6 and 12 months post baseline for effectiveness at the patient level. A parallel process and economic analysis from a healthcare sector perspective will also be performed. Patients will be allocated to routine care (control group) or the BetterBack☺ MOC (intervention group) according to a stepped cluster dogleg structure with two assessments in routine care. Experimental conditions will be compared and causal mediation analysis investigated. Qualitative HCP and patient experiences of the BetterBack☺ MOC will also be investigated.

DISSEMINATION

The findings will be published in peer-reviewed journals and presented at national and international conferences. Further national dissemination and implementation in Sweden and associated national quality register data collection are potential future developments of the project.

Factor structure of the German version of the pain attitudes and beliefs scale for physiotherapists

The Pain Attitudes and Beliefs Scale for Physiotherapists (PABS-PT) is a questionnaire that is frequently used to measure the treatment orientation of physiotherapists and other healthcare providers toward low back pain (LBP). Previous validation studies of the PABS-PT have reported consistently that exploratory factor analysis (EFA) yielded a two-factor model with the factors "biomedical" and "biopsychosocial." However, there remain concerns regarding the composition of these two factors and the internal consistency of the "biopsychosocial" factor. The objective of this study was to replicate the previous validation study on the German PABS-PT. EFA was implemented to reexamine the underlying structure of the scale, and confirmatory factor analysis (CFA) was used to test the fit of the hypothesized two-factor model. Results of the initial validation study were not replicated. EFA indicated that a two-factor solution is an inadequate representation of the PABS-PT data, and CFA showed insufficient fit of the hypothesized two-factor model to the PABS-PT data. Our results indicate a need for caution when using the PABS-PT to measure physiotherapists' orientation toward LBP, particularly in measuring the magnitude of a biopsychosocial orientation.

An evaluation of a pain education programme for physiotherapists in clinical practice

OBJECTIVE

The present study evaluated the implementation and acceptability of a pain education programme delivered to physiotherapists in clinical practice.

METHODS

A pre-test/post-test design with 10 physiotherapists was employed. Descriptive and inferential statistics were used for outcome measure data. Focus groups were carried out with seven physiotherapists within 1 month post-intervention. These data were analysed using the framework approach.

RESULTS

Ten musculoskeletal physiotherapists were recruited. It was possible to develop and deliver the intervention and this was found to be acceptable to physiotherapists within clinical practice. The study explored trends within outcome measures, and one was considered appropriate. The focus groups yielded three interlinked themes, which related to the impact of the programme: "providing a context for pain education", "influence on aspects of the patient-therapist encounter" and "logistics of the education programme in clinical practice".

CONCLUSIONS

A pain education programme delivered to physiotherapists in clinical practice was both possible to deliver and acceptable to participants. A key strength of the programme was the applicability to real-life practice, which was valued by physiotherapists. While physiotherapists felt that pain neurophysiology education was important, they reported lacking confidence in implementing their pain neurophysiology knowledge with patients. Thus, more time is needed to focus on pain neurophysiology education, with the aim of increasing confidence with the application of this approach in clinical practice.

Effects of Median Nerve Neural Mobilization in Treating Cervicobrachial Pain: A Randomized Waiting List-Controlled Clinical Trial

BACKGROUND

There is a current lack of sufficiently high-quality randomized controlled clinical trials that measure the effectiveness of neural tissue mobilization techniques such as median nerve neural mobilization (MNNM) and their specific effects on cervicobrachial pain (CP). The aim of this study was to compare the effectiveness of MNNM in subjects with CP vs. a waiting list control group (WLCG).

METHODS

A single-blinded, parallel, randomized controlled clinical trial was performed (NCT02596815). Subjects were recruited with a medical diagnosis of CP corroborated by magnetic resonance imaging. In total, 156 individuals were screened, 60 subjects were recruited, and 51 completed the trial. Pain intensity reported using the Numeric Rating Scale for Pain (NRSP; primary outcome), cervical range of motion (CROM), and functionality using the Quick Disabilities of the Arm, Shoulder and Hand (QuickDASH) scale were the outcome measurements. Assessments were conducted at baseline and 1 hour after treatment (intervention days 1, 15, and 30). Therefore, MNNM was implemented with 30 days of follow-up.

RESULTS

The NRSP values of the MNNM group were significantly (P < 0.0001; 95% confidence interval [CI]) superior to those obtained in the WLCG. Subjects treated with MNNM reported an NRSP decrease of 3.08 points at discharge. CROM and QuickDASH outcome values were significantly (P ˂ 0.0001; 95% CI) improved only in the MNNM group. Hedges' g showed a very large effect of the MNNM intervention.

CONCLUSION

MNNM may be superior to no treatment in reducing pain and increasing function in the affected upper limbs of subjects with CP.

Rasch analysis resulted in an improved Norwegian version of the Pain Attitudes and Beliefs Scale(PABS)

Background and aim

There is evidence that clinicians’ pain attitudes and beliefs are associated with the pain beliefs and illness perceptions of their patients and furthermore influence their recommendations for activity and work to patients with back pain. The Pain Attitudes and Beliefs Scale (PABS) is a questionnaire designed to differentiate between biomedical and biopsychosocial pain attitudes among health care providers regarding common low back pain. The original version had 36 items, and several shorter versions have been developed. Concern has been raised over the PABS’ internal construct validity because of low internal consistency and low explained variance. The aim of this study was to examine and improve the scale’s measurement properties and item performance.

Methods

A convenience sample of 667 Norwegian physiotherapists provided data for Rasch analysis. The biomedical and biopsychosocial subscales of the PABS were examined for unidimensionality, local response independency, invariance, response category function and targeting of persons and items. Reliability was measured with the person separation index (PSI). Items originally excluded by the developers of the scale because of skewness were re-introduced in a second analysis.

Results

Our analysis suggested that both subscales required removal of several psychometrically redundant and misfitting items to satisfy the requirements of the Rasch measurement model. Most biopsychosocial items needed revision of their scoring structure. Furthermore, we identified two items originally excluded because of skewness that improved the reliability of the subscales after reintroduction. The ultimate result was two strictly unidimensional subscales, each consisting of seven items, with invariant item ordering and free from any form of misfit. The unidimensionality implies that summation of items to valid total scores is justified. Transformation tables are provided to convert raw ordinal scores to unbiased interval-level scores. Both subscales were adequately targeted at the ability level of our physiotherapist population. Reliability of the biomedical subscale as measured with the PSI was 0.69. A low PSI of 0.64 for the biopsychosocial subscale indicated limitations with regard to its discriminative ability.

Conclusions

Rasch analysis produced an improved Norwegian version of the PABS which represents true (fundamental) measurement of clinicians’ biomedical and biopsychosocial treatment orientation. However, researchers should be aware of the low discriminative ability of the biopsychosocial subscale when analyzing differences and effect changes.

Implications

The study presents a revised PABS that provides interval-level measurement of clinicians’ pain beliefs. The revision allows for confident use of parametric statistical analysis. Further examination of discriminative validity is required.

Evaluation of measurement properties of self-administered PROMs aimed at patients with non-specific shoulder pain and "activity limitations": a systematic review

OBJECTIVE

To critically appraise and compare the measurement properties of self-administered patient-reported outcome measures (PROMs) focussing on the shoulder, assessing "activity limitations."

STUDY DESIGN

Systematic review. The study population had to consist of patients with shoulder pain. We excluded postoperative patients or patients with generic diseases. The methodological quality of the selected studies and the results of the measurement properties were critically appraised and rated using the COSMIN checklist.

RESULTS

Out of a total of 3427 unique hits, 31 articles, evaluating 7 different questionnaires, were included. The SPADI is the most frequently evaluated PROM and its measurement properties seem adequate apart from a lack of information regarding its measurement error and content validity.

CONCLUSION

For English, Norwegian and Turkish users, we recommend to use the SPADI. Dutch users could use either the SDQ or the SST. In German, we recommend the DASH. In Tamil, Slovene, Spanish and the Danish languages, the evaluated PROMs were not yet of acceptable validity. None of these PROMs showed strong positive evidence for all measurement properties. We propose to develop a new shoulder PROM focused on activity limitations, taking new knowledge and techniques into account.

Systematic Review of the Clinical Disease Severity Indices for Inflammatory Bowel Disease

BACKGROUND

Clinical disease severity indices are increasingly being used in choosing treatment and monitoring the response of patients with inflammatory bowel disease (IBD). The aim of this study was to systematically review the clinical disease severity indices in IBD and to appraise their measurement properties and methodological quality.

METHODS

We searched the MEDLINE, Embase, and PsycINFO databases for original articles describing the development and/or evaluation of one or more of the measurement properties of clinical disease severity indices used in IBD. We assessed these properties (e.g., internal consistency, reliability, validity, responsiveness) using a standardized checklist.

RESULTS

We examined the full text of 142 articles that we deemed potentially eligible and identified 22 clinical disease severity indices in IBD. No clinical disease index has met all the required measurement properties. All of the validation studies were not descriptive enough to allow assessment of their methodology.

CONCLUSIONS

Although commonly used in multiple clinical trials, none of the clinical disease severity indices in IBD had all the required measurement properties. Further validation studies are required.

Influence of Physical Therapists' Kinesiophobic Beliefs on Lifting Capacity in Healthy Adults

BACKGROUND

Physical therapists' recommendations to patients to avoid daily physical activity can be influenced by the therapists' kinesiophobic beliefs. Little is known about the amount of influence of a physical therapist's kinesiophobic beliefs on a patient's actual lifting capacity during a lifting test.

OBJECTIVE

The objective of this study was to determine the influence of physical therapists' kinesiophobic beliefs on lifting capacity in healthy people.

DESIGN

A blinded, cluster-randomized cross-sectional study was performed.

METHODS

The participants (n=256; 105 male, 151 female) were physical therapist students who performed a lifting capacity test. Examiners (n=24) were selected from second-year physical therapist students. Participants in group A (n=124) were tested in the presence of an examiner with high scores on the Tampa Scale of Kinesiophobia for health care providers (TSK-HC), and those in group B (n=132) were tested in the presence of an examiner with low scores on the TSK-HC. Mixed-model analyses were performed on lifting capacity to test for possible (interacting) effects.

RESULTS

Mean lifting capacity was 32.1 kg (SD=13.6) in group A and 39.6 kg (SD=16.4) in group B. Mixed-model analyses revealed that after controlling for sex, body weight, self-efficacy, and the interaction between the examiners' and participants' kinesiophobic beliefs, the influence of examiners' kinesiophobic beliefs significantly reduced lifting capacity by 14.4 kg in participants with kinesiophobic beliefs and 8.0 kg in those without kinesiophobic beliefs.

LIMITATIONS

Generalizability to physical therapists and patients with pain should be studied.

CONCLUSIONS

Physical therapists' kinesiophobic beliefs negatively influence lifting capacity of healthy adults. During everyday clinical practice, physical therapists should be aware of the influence of their kinesiophobic beliefs on patients' functional ability.

[Health care professionals' attitudes and beliefs towards older back pain patients. Analysis of the assessment methods and research gaps]

In recent years, the influence of doctors' and therapists' attitudes and beliefs for the treatment of chronic low back pain patients has been increasingly investigated. Attitudes and beliefs of health care providers have been identified as important contributors for an activity based, guideline-oriented therapeutic approach and different questionnaires were developed to evaluate this interaction. Recent reviews discuss the quality of those questionnaires as well as the impact of attitudes towards therapeutic choices and activity recommendations by health care professionals. This article summarizes these results and illuminates transferability of existing questionnaires to older patients with back pain. A literature review shows that most studies were conducted with physiotherapists and general practitioners. At present the most thoroughly investigated tool for its psychometric validity is the Pain Attitudes and Beliefs Scale (PABS). The PABS could be a suitable instrument for examinations regarding therapist attitudes towards older pain patients by using more age-neutral wording. Concluding from the literature, an additional methodological assessment tool could be the utilization of case vignettes. However, those case vignettes, which had been used in studies in England, should be translated and culturally adapted before its application in Germany. Overall, it must be assumed that attitudes and beliefs of clinicians are also important in the care of older patients in pain. With regards to activity recommendations, ageism and the special situation of older people should also be taken into account including possible risk of falling, multimorbidity, polypharmacy, and cognitive impairment. These topics should all be considered in adapted or newly developed questionnaires for the evaluation of attitudes and beliefs of health care providers regarding back pain in older persons.

Pragmatic Implementation of a Stratified Primary Care Model for Low Back Pain Management in Outpatient Physical Therapy Settings: Two-Phase, Sequential Preliminary Study

BACKGROUND

The effectiveness of risk stratification for low back pain (LBP) management has not been demonstrated in outpatient physical therapy settings.

OBJECTIVE

The purposes of this study were: (1) to assess implementation of a stratified care approach for LBP management by evaluating short-term treatment effects and (2) to determine feasibility of conducting a larger-scale study.

DESIGN

This was a 2-phase, preliminary study.

METHODS

In phase 1, clinicians were randomly assigned to receive standard (n=6) or stratified care (n=6) training. Stratified care training included 8 hours of content focusing on psychologically informed practice. Changes in LBP attitudes and beliefs were assessed using the Pain Attitudes and Beliefs Scale for Physiotherapists (PABS-PT) and the Health Care Providers Pain and Impairment Relationship Scale (HC-PAIRS). In phase 2, clinicians receiving the stratified care training were instructed to incorporate those strategies in their practice and 4-week patient outcomes were collected using a numerical pain rating scale (NPRS), and the Oswestry Disability Index (ODI). Study feasibility was assessed to identify potential barriers for completion of a larger-scale study.

RESULTS

In phase 1, minimal changes were observed for PABS-PT and HC-PAIRS scores for standard care clinicians (Cohen d=0.00-0.28). Decreased biomedical (-4.5±2.5 points, d=1.08) and increased biopsychosocial (+5.5±2.0 points, d=2.86) treatment orientations were observed for stratified care clinicians, with these changes sustained 6 months later on the PABS-PT. In phase 2, patients receiving stratified care (n=67) had greater between-group improvements in NPRS (0.8 points; 95% confidence interval=0.1, 1.5; d=0.40) and ODI (8.9% points; 95% confidence interval=4.1, 13.6; d=0.76) scores compared with patients receiving standard physical therapy care (n=33).

LIMITATIONS

In phase 2, treatment was not randomly assigned, and therapist adherence to treatment recommendations was not monitored. This study was not adequately powered to conduct subgroup analyses.

CONCLUSIONS

In physical therapy settings, biomedical orientation can be modified, and risk-stratified care for LBP can be effectively implemented. Findings from this study can be used for planning of larger studies.

Individualised cognitive functional therapy compared with a combined exercise and pain education class for patients with non-specific chronic low back pain: study protocol for a multicentre randomised controlled trial

INTRODUCTION

Non-specific chronic low back pain (NSCLBP) is a very common and costly musculoskeletal disorder associated with a complex interplay of biopsychosocial factors. Cognitive functional therapy (CFT) represents a novel, patient-centred intervention which directly challenges pain-related behaviours in a cognitively integrated, functionally specific and graduated manner. CFT aims to target all biopsychosocial factors that are deemed to be barriers to recovery for an individual patient with NSCLBP. A recent randomised controlled trial (RCT) demonstrated the superiority of individualised CFT for NSCLBP compared to manual therapy combined with exercise. However, several previous RCTs have suggested that class-based interventions are as effective as individualised interventions. Therefore, it is important to examine whether an individualised intervention, such as CFT, demonstrates clinical effectiveness compared to a relatively cheaper exercise and education class. The current study will compare the clinical effectiveness of individualised CFT with a combined exercise and pain education class in people with NSCLBP.

METHODS AND ANALYSIS

This study is a multicentre RCT. 214 participants, aged 18-75 years, with NSCLBP for at least 6 months will be randomised to one of two interventions across three sites. The experimental group will receive individualised CFT and the length of the intervention will be varied in a pragmatic manner based on the clinical progression of participants. The control group will attend six classes which will be provided over a period of 6-8 weeks. Participants will be assessed preintervention, postintervention and after 6 and 12 months. The primary outcomes will be functional disability and pain intensity. Non-specific predictors, moderators and mediators of outcome will also be analysed.

ETHICS AND DISSEMINATION

Ethical approval has been obtained from the Mayo General Hospital Research Ethics Committee (MGH-14-UL). Outcomes will be disseminated through publication according to the SPIRIT statement and will be presented at scientific conferences.

Attitudes and beliefs of Australian chiropractors' about managing back pain: a cross-sectional study

Background

Chiropractors are frequent providers of care for patients with lower back pain. Biopsychosocial approaches to managing patients are regarded as best practice and are gaining wider acceptance. Recent evidence suggests that practitioners’ attitudes and beliefs may also have an important effect on patients’ recovery from back pain. Past studies have pooled manual therapists from differing professions. Dissonant findings have been hypothesised as being a result of the chiropractic subpopulation within multi-practitioner participant pools who are hypothesised to focus on biomedical aspects of treatment and minimize biopsychosocial dimensions.

The aim of this study is to determine whether a study population of only chiropractors would demonstrate similar attitudes and beliefs to other manual therapists’ biopsychosocial or biomedical approach to the management of their patients.

Methods

A survey of chiropractors in Victoria Australia in September 2010 was undertaken utilising the Pain Attitude and Belief Scale (PABS.PT), a tool which has been developed to determine the orientation (biopsychosocial or biomedical approach) of practitioners to the management of people with low back pain. The survey also obtained demographic data from respondents to determine whether variables such as education, gender or practice related factors influenced their orientation.

Results

The overall response rate was 29% (n = 218). The majority of the sample was male (68%), with a mean age of 44 years. The 6 point Likert scale scores were 34.5 (6.3) for the biomedical factor scale and 31.4 (4.1) for the biopsychosocial scale. Internal consistency of the psychosocial subscale was poor. None of the demographic variables were found to influence the biomedical or psychosocial scales.

Conclusions

Chiropractors in the state of Victoria were found to have similar biomedical and psychosocial orientations in their attitudes and beliefs when compared to other manual therapists’ levels of previous studies from differing cultural and educational backgrounds. This study was unable to replicate any of the relationships from past studies with any of the demographic variables. The psychosocial scale internal consistency may be a significant factor in this non-finding. Future research should address the identification of more robust items of the biopsychosocial attitudes of Victorian chiropractors toward treating lower back pain.

Systematic review of health-related quality of life measures for inflammatory bowel disease

BACKGROUND AND AIM

Several measures have been developed to assess the health-related quality of life [HRQoL] of patients with inflammatory bowel disease [IBD]. Our aim is to systematically review the HRQoL measures specific for patients with IBD and to appraise their measurement properties and methodological quality.

METHODS

We searched the PubMed, Embase, and PsycINFO databases for original articles describing the development and/or evaluation of one or more of the measurement properties [e.g. internal consistency, reliability, validity, responsiveness] of HRQoL measures specific for IBD. We assessed the measurement properties and examined the methodological quality of the measurement properties of each instrument using a standardized checklist.

RESULTS

We examined the full text of 75 articles that we deemed potentially eligible and identified 10 disease-specific HRQoL measures in IBD that covered different aspects of patients' lives. Internal consistency, construct validity, and content validity were the commonly evaluated measurement properties. Seven HRQoL measures scored positive for at least four of eight measurement properties. The majority of studies were rated as 'fair' to 'poor' when assessing their methodology quality. The most established HRQoL measure in the literature was the Inflammatory Bowel Disease Questionnaire [IBDQ].

CONCLUSIONS

Most of the included HRQoL measures did not include all the required measurement properties or had a problem with their methodological quality. The most widely used and validated measure was the IBDQ. Further validation studies are required to support the use of other HRQoL measures.

Satisfaction measurement instruments for healthcare service users: a systematic review

Patient satisfaction surveys can be an interesting way to improve quality and discuss the concept of patient-centered care. This study aimed to conduct a systematic review of the validated patient satisfaction measurement instruments applied in healthcare. The systematic review searched the MEDLINE/PubMed, LILACS, SciELO, Scopus and Web of Knowledge. The search strategy used the terms: "Patient Satisfaction" AND "Patient centered care" AND "Healthcare survey OR Satisfaction questionnaire" AND "Psychometric properties". 37 studies were included and almost all studies showed that satisfaction is a multidimensional construct. In these studies, 34 different instruments were used and most surveys contained the dimension patient-healthcare professional interactions, physical environment and management process. The COSMIN score for methodological quality showed that most of them scored a good or fair average. We can conclude that there is not a gold standard instrument for patient satisfaction assessment but some dimensions are essential for this construct.

The development and exploratory analysis of the Back Pain Attitudes Questionnaire (Back-PAQ)

OBJECTIVES

To develop an instrument to assess attitudes and underlying beliefs about back pain, and subsequently investigate its internal consistency and underlying structures.

DESIGN

The instrument was developed by a multidisciplinary team of clinicians and researchers based on analysis of qualitative interviews with people experiencing acute and chronic back pain. Exploratory analysis was conducted using data from a population-based cross-sectional survey.

SETTING

Qualitative interviews with community-based participants and subsequent postal survey.

PARTICIPANTS

Instrument development informed by interviews with 12 participants with acute back pain and 11 participants with chronic back pain. Data for exploratory analysis collected from New Zealand residents and citizens aged 18 years and above. 1000 participants were randomly selected from the New Zealand Electoral Roll. 602 valid responses were received.

MEASURES

The 34-item Back Pain Attitudes Questionnaire (Back-PAQ) was developed. Internal consistency was evaluated by the Cronbach α coefficient. Exploratory analysis investigated the structure of the data using Principal Component Analysis.

RESULTS

The 34-item long form of the scale had acceptable internal consistency (α=0.70; 95% CI 0.66 to 0.73). Exploratory analysis identified five two-item principal components which accounted for 74% of the variance in the reduced data set: 'vulnerability of the back'; 'relationship between back pain and injury'; 'activity participation while experiencing back pain'; 'prognosis of back pain' and 'psychological influences on recovery'. Internal consistency was acceptable for the reduced 10-item scale (α=0.61; 95% CI 0.56 to 0.66) and the identified components (α between 0.50 and 0.78).

CONCLUSIONS

The 34-item long form of the scale may be appropriate for use in future cross-sectional studies. The 10-item short form may be appropriate for use as a screening tool, or an outcome assessment instrument. Further testing of the 10-item Back-PAQ's construct validity, reliability, responsiveness to change and predictive ability needs to be conducted.

The psychometric properties of the PABS-PT in neck pain patients: a validation study

OBJECTIVE

This study aims to assess the reliability and validity of the Pain Attitudes and Beliefs Scale for Physiotherapists (PABS-PT) in neck pain patients. Three research goals were formulated. (1): to reexamine the factor structure of the PABS-PT, (2) to assess the test-retest reliability of the PABS-PT and (3) to determine the construct validity of the biomedical factor of the PABS-PT.

METHODS

Manual therapists (n = 272) included in this study participated in an educational upgrade program for a professional masters' degree in the Netherlands and completed the Health Care Providers' Pain and Impairment Relationship Scale and the PABS-PT. Principal Axis Factor analysis was performed and correlation coefficients were calculated. In addition, Bland and Altman plots and the smallest real difference were determined.

RESULTS

We performed factor analysis on 182 questionnaires and test-rest calculations on 73 questionnaires. The principal factor analysis confirmed the existing interpretable 2-factor model of a 'biomedical treatment orientation' and a 'behavioral treatment orientation'. Test-retest reliability was 'moderate' to 'good' and construct validity for the biomedical factor was 'moderate' to 'substantial'.

CONCLUSION

The PABS-PT shows a consistent factor structure and good test-retest reliability and construct validity. More research is needed to gain further insight in the interplay between implicit and explicit attitudes and the dynamics of the PABS-PT score across different body parts.
