The IMPROVE trial: study protocol for a pragmatic cluster randomised controlled trial to assess the effectiveness of using lay health workers to improve uptake and completion of pulmonary rehabilitation in patients with chronic obstructive pulmonary disease.

BACKGROUND: Pulmonary rehabilitation (PR) is a programme of exercise and education and the most effective treatment for the symptoms and disability associated with chronic obstructive pulmonary disease. However, the benefits of PR are limited by poor uptake and completion. This trial will determine whether using trained volunteer lay health workers, called "PR buddies," improves uptake and completion of PR and is cost-effective. This trial protocol outlines the methods for evaluating effectiveness, cost-effectiveness, and acceptability. METHODS: The IMPROVE trial is a pragmatic, open, cluster randomised controlled trial planned in 38 PR services across England and Wales. PR services will be randomised to either intervention arm-offering support from PR buddies to patients with chronic obstructive pulmonary disease-or to usual care as the control arm. PR staff in trial sites randomised to the intervention arm will receive training in recruiting and training PR buddies. They will deliver training to volunteers, recruited from among people who have recently completed PR in their service. The 3-day PR-buddy training programme covers communication skills, confidentiality, boundaries of the PR-buddy role and behaviour change techniques to help patients overcome obstacles to attending PR. An internal pilot will test the implementation of the trial in eight sites (four intervention sites and four in control arm). The primary outcome of the trial is the uptake and completion of PR. A process evaluation will investigate the acceptability of the intervention to patients, PR staff and the volunteer PR buddies, and intervention fidelity. We will also conduct a cost-effectiveness analysis. DISCUSSION: Improving outcomes for chronic obstructive pulmonary disease and access to PR are priorities for the UK National Health Service (NHS) in its long-term plan. The trial hypothesis is that volunteer PR buddies, who are recruited and trained by local PR teams, are an effective and cost-effective way to improve the uptake and completion rates of PR. The trial is pragmatic, since it will test whether the intervention can be incorporated into NHS PR services. Information obtained in this trial may be used to influence policy on the use of PR buddies in PR and other similar services in the NHS. TRIAL REGISTRATION: ISRCTN12658458. Registered on 23/01/2023.

Effectiveness of remotely delivered motivational conversations on health outcomes in patients living with musculoskeletal conditions: A systematic review and meta-analysis.

OBJECTIVE: To evaluate the efficacy of remotely delivered motivational conversations on health outcomes in musculoskeletal populations. METHODS: Four electronic databases (inception-March 2022) were searched and combined with grey literature. Randomised control trials (RCTs) evaluating the effect of remotely delivered motivational conversation-based interventions within musculoskeletal populations, using valid measures of pain, disability, quality of life (QoL), or self-efficacy were included. Overall quality was assessed using GRADE criteria. Meta-analyses were performed using random effects models with pooled effect sizes expressed as standardised mean differences ( ± 95%CIs). RESULTS: Twelve RCTs were included. Meta-analyses revealed very-low to moderate quality evidence that remote interventions have a positive effect on pain and disability both immediately post intervention and at long-term follow-up compared to control, and have a positive effect on self-efficacy immediately post intervention. There was no effect on QoL immediately post intervention or at long-term follow up. CONCLUSION: Remotely delivered motivation-based conversational interventions have a positive effect on pain, disability, and self-efficacy but not on QoL. PRACTICE IMPLICATIONS: Motivational conversations, delivered remotely, may be effective in improving some health-related outcomes in MSK populations. However, higher quality evidence is needed to determine optimal intervention durations, and dosing frequencies using sufficient sample sizes and follow-up time frames.

Factors associated with concerns about falling and activity restriction in older adults after hip fracture: a mixed-methods systematic review.

PURPOSE: To investigate factors contributing to concerns about falling and activity restriction in the community among older adults who had a hip fracture. METHODS: A mixed method systematic review with a convergent segregated approach. We searched Medline, Embase, PsycInfo, PEDRo, CINAHL and the Cochrane library. Results were synthesised narratively considering physical, psychological, environmental, care, and social factors and presented in tables. Critical appraisal was completed in duplicate. RESULTS: We included 19 studies (9 qualitative, 9 observational, 1 mixed methods) representing 1480 individuals and 23 factors related to concerns about falling and activity restriction. Physical factors included falls history, comorbidities, balance, strength, mobility and functionality. Psychological factors included anxiety and neuroticism scores, perceived confidence in/control over rehabilitation and abilities, and negative/positive affect about the orthopaedic trauma, pre-fracture abilities and future needs. Environmental factors included accessibility in the home, outdoors and with transport. Social and care factors related to the presence or absence of formal and informal networks, which reduced concerns and promoted activity by providing feedback, advice, encouragement, and practical support. CONCLUSION: These findings highlight that to improve concerns about falling and activity restriction after hip fracture, it is important to: improve physical and functional abilities; boost self-confidence; promote positive affect; involve relatives and carers; increase access to clinicians, and; enhance accessibility of the home, outdoors and transport. Most factors were reported on by a small number of studies of varying quality and require replication in future research.

Challenges of Measuring Self-Reported Exposure to Occupational Biomechanical Risk Factors Amongst People with Low Literacy Engaged in Manual Labour: Findings from a Cross-Cultural Adaptation and Psychometric Investigation in an African Population with Chronic Low Back Pain.

PURPOSE: Occupational biomechanical factors are implicated in the aetiology and progression of low back pain (LBP). This study cross-culturally adapted and psychometrically investigated the Occupational Risk Factor Questionnaire (ORFQ) in a low literate Nigerian Igbo population with chronic LBP. METHODS: Forward and back translation of the original ORFQ by clinical and non-clinical translators was followed by an expert committee review. The adapted ORFQ was pre-tested amongst rural Nigerian adults with chronic LBP using cognitive think-aloud interviewing. Internal consistency (Cronbach's alpha) and test-retest reliability (unweighted and linear weighted k statistic for item-by-item agreement, and intra-class correlation coefficient-ICC) were investigated amongst 50 rural and urban Nigerian dwellers with chronic LBP. Spearman's correlation and regression analyses were conducted with the Igbo-ORFQ, and measures of disability [World Health Organisation Disability Assessment Schedule (WHODAS 2.0), Roland Morris Disability Questionnaire (RMDQ), Back performance scale (BPS)], pain intensity [Eleven-point box scale (BS-11)] and social support [Multidimensional Scale of Perceived Social Support (MSPSS)], to test construct validity with 200 rural Nigerian dwellers with chronic LBP. RESULTS: Cross-cultural adaptation highlighted difficulty conceptualising and concretising exposure to biomechanical risk factors. Item-by-item agreement, internal consistency (α = 0.84) and intraclass correlation coefficient (ICC = 0.83) were good. Some unexpected direction of associations between the biomechanical components of the Igbo-ORFQ, and disability, pain intensity, and social support prohibits establishment of construct validity. CONCLUSION: Prospective studies comparing the Igbo-ORFQ to other measures of exposure to occupational biomechanical risk factors are required to establish the construct validity of the Igbo-ORFQ.

Mind and skin: Exploring the links between inflammation, sleep disturbance and neurocognitive function in patients with atopic dermatitis.

Atopic dermatitis (AD) is a chronic, pruritic and inflammatory, dry skin condition with many known comorbidities. These include airway disease, food allergies, atopic eye disease and autoimmune conditions. Furthermore, there is often significant sleep disturbance as well as increased psychological distress and mental health problems. Severe AD therefore often has a significant impact on the quality of life of both patients and their families. In this review we discuss recent findings on the putative links between AD, its association with itch, sleep disturbance and neuropsychiatric morbidity, including the role of inflammation in these conditions. Itch was thought to predominantly drive sleep disruption in AD. We now understand changes in sleep influence immune cell distribution and the associated inflammatory cytokines, which suggests a bidirectional relationship between AD and sleep. We also increasingly recognize inflammation as a key driver in psychological symptoms and disorders. The link between cutaneous, systemic and possible brain inflammation could at least in part be driven by the sleep deprivation and itch-driven neuronal proliferation seen in AD.

Exploring needs, barriers to, and facilitators of rehabilitation exercise following revision hip replacement - A grounded theory study.

PURPOSE: Evidence on rehabilitation after revision total hip replacement (THR) is inadequate and development of rehabilitation interventions is warranted. Even so, little is known about patients' experiences with revision THR rehabilitation. This study aimed to explore patients' rehabilitation exercise experiences after revision THR. MATERIALS AND METHODS: Using constructivist grounded theory, we conducted semi-structured qualitative interviews with twelve patients with completed or almost completed rehabilitation exercise after revision THR. Data collection and analysis were a constant comparative process conducted in three phases; initial, focused, and theoretical. FINDINGS: From the data, we generated a substantial theory of the participant's circumstances and ability to integrate rehabilitation exercise into their everyday life after revision THR. Four categories were constructed based on patients' experiences in different contexts: hesitance, fear avoidance, self-commitment, and fidelity. CONCLUSIONS: This study highlighted that patients' expectations, past experiences, attitudes, trusts, and circumstances interact to influence engagement and adherence to rehabilitation exercise and described four categories relating to the integration of revision THR rehabilitation exercise into their everyday life. Clinicians should be aware of and account for these categories during rehabilitation exercise. Tailored individual rehabilitation exercise interventions and clinician approaches to optimize engagement and adherence are needed among patients with revision THR.

Patients' rehabilitation exercise experiences after revision total hip replacement may serve as guidance for clinicians.A need exists to tailor individual rehabilitation interventions and clinicians' approaches to optimize patients' engagement and rehabilitation exercise adherence following revision total hip replacement.Clinicians can tailor rehabilitation exercise for patients with revision total hip replacement by focusing on therapeutic relationships, support needs, and physical function while incorporating insights from previous rehabilitation exercise experiences.An important goal of rehabilitation exercise is to enhance patient engagement, thereby facilitating the integration of rehabilitation exercises into the patients' everyday life.

What non-pharmacological and non-invasive pain management interventions are available for individuals from Turkish-speaking ethnic groups with non-malignant chronic pain? A scoping review of published literature.

Objectives: A scoping review was selected to explore what non-pharmacological and non-invasive pain management interventions are available for individuals from Turkish-speaking ethnic groups with chronic pain and what represents the most appropriate intervention. Inclusion Criteria: Adults with non-malignant chronic pain from Turkish-speaking ethnic groups residing in or outside of Turkey. All non-pharmacological and non-invasive pain management interventions were considered. No limits were placed on geographic location, gender, sex or healthcare setting. Methods: The MEDLINE database was searched for published literature in April 2022. An English language filter was applied. No limits were placed on study design or date of publication. Data was charted from eligible studies into a data extraction table. Key concepts were identified during data extraction by DN. Results: Eleven studies were included in the final review. All were conducted within a quantitative research paradigm. The studies were completed in Turkey (7), Belgium (1), Sweden (1) and Switzerland (1). One was a multi-country review. No studies were conducted in the UK. The primary interventions were heterogenous and included: pain science education (2), cognitive behavioural therapy (2), transcranial magnetic stimulation (1), balneotherapy (1), extracorporeal shockwave therapy (1), transcutaneous electrical nerve stimulation (1), wool therapy (1), exercise and patient dialogues (1) and aromatherapy massage and reflexology (1). Location of pain, outcome measures and timings of follow-ups were heterogeneous. Conclusions: Intervention heterogeneity, exclusively quantitative methodology and absence of studies completed in the UK meant no conclusions could be made on what represents the most appropriate non-pharmacological and non-invasive interventions intervention for individuals from Turkish speaking ethnic groups with non-malignant chronic pain.

Improving Mental Health Help-Seeking Among Male University Students: A Series of Gender-Sensitive Mental Health Feasibility Interventions.

One-third of students experience a mental health condition associated with decreased academic functioning and increased risk of dropping out. While mental health difficulties are lower among male students, they are twice as likely to die by suicide. Although the importance of gender-sensitive interventions for male students has been emphasized, feasible and effective approaches are unexplored. This investigation conducted three gender-sensitive feasibility interventions for male students to evaluate acceptability, changes to help-seeking and mental health outcomes. Three interventions were delivered to 24 male students. The interventions included the following: Intervention 1-a formal intervention targeting male students, Intervention 2-a formal intervention that adopted gender-sensitive language and promoted positive masculine traits, and Intervention 3-an informal drop-in offering a social space providing health information. These were evaluated for acceptability, attitudes to help-seeking, and mental health outcomes. All interventions were equally acceptable. The informal drop-in was more acceptable, having better engagement from male students who have greater conformity to maladaptive masculine traits, more negative attitudes to help-seeking, higher levels of self-stigma, who were less likely to have used mental health support before and belonged to an ethnic minority. These findings indicate differences in acceptability, particularly uptake, for hard-to-engage male students. Informal strategies help reach male students who would otherwise not engage with mental health support, familiarize them with help-seeking, and connect them with pre-existing mental health interventions. More work needs to be carried out using larger samples to investigate the efficacy of informal interventions to engage male students.

The challenge of exercise (non-)adherence: a scoping review of methods and techniques applied to improve adherence to physical activity and exercise in people with inflammatory arthritis.

Objectives: The aims were to explore the nature of methods/techniques applied to improve adherence to physical activity (PA) and exercise in people with inflammatory arthritis and to identify whether studies were theory based and/or used behaviour change techniques (BCTs). Methods: Searches were undertaken of English language articles within four databases: Embase, Medline, PsycINFO and Cochrane. Articles were included if they assessed adherence to a PA and/or exercise intervention. A narrative synthesis of the findings is reported. Results: Of 1909 studies screened, 18 studies met inclusion criteria. Adherence was most frequently included as a secondary outcome. Reporting of adherence measures was poor, in that 13 studies did not use a validated measure of adherence, with only three validated measures being identified. The majority of studies were not theory driven (n = 13), although the health belief model was the most used theoretical framework (n = 5). Only two studies mentioned both theory and BCTs. Four studies reported components that were mapped onto BCTs, with goal setting being the most prevalent. Conclusion: This scoping review found that adherence to PA and/or exercise interventions was rarely the focus of research, despite its importance in maintaining health in people with inflammatory arthritis. Where research has been conducted in this area, serious shortcomings were revealed, in that psychological theory, evidence-based BCTs derived from theory and valid adherence measures were not used to inform intervention design and target adherence, meaning that interventions were suboptimal. These results suggest that there is considerable room for improvement and that more high-quality research is required to investigate determinants of adherence and develop impactful interventions.

Social learning in a nocturnal marsupial: is it a possum-ability?

Social learning can reduce the costs associated with trial-and-error learning. There is speculation that social learning could contribute to trap and bait avoidance in invasive species like the common brushtail possum (Trichosurus vulpecula)-a marsupial for which social learning has not previously been investigated. In large outdoor pens, we presented wild-caught 'demonstrator' possums with puzzle devices containing an attractive food reward; 2 of 8 demonstrators accessed the reward the first night the puzzle was presented and another three succeeded on later nights. Meanwhile, 'observer' possums in adjacent pens watched the demonstrators for five nights and then were given the opportunity to solve the puzzle themselves; 15 of 15 succeeded on their first night (a highly significant improvement). This experiment thus provides strong evidence of social learning by common brushtail possums. Future research should investigate whether information about aversive stimuli (such as traps and toxic baits) can similarly be transmitted between possums by social learning; if so, this could have important implications for possum pest control.

Gait rehabilitation for foot and ankle impairments in early rheumatoid arthritis: a feasibility study of a new gait rehabilitation programme (GREAT Strides).

BACKGROUND: Foot impairments in early rheumatoid arthritis are common and lead to progressive deterioration of lower limb function. A gait rehabilitation programme underpinned by psychological techniques to improve adherence, may preserve gait and lower limb function. This study evaluated the feasibility of a novel gait rehabilitation intervention (GREAT Strides) and a future trial. METHODS: This was a mixed methods feasibility study with embedded qualitative components. People with early (< 2 years) rheumatoid arthritis (RA) and foot pain were eligible. Intervention acceptability was evaluated using a questionnaire. Adherence was evaluated using the Exercise Adherence Rating Scale (EARS). Safety was monitored using case report forms. Participants and therapists were interviewed to explore intervention acceptability. Deductive thematic analysis was applied using the Theoretical Framework of Acceptability. For fidelity, audio recordings of interventions sessions were assessed using the Motivational Interviewing Treatment Integrity (MITI) scale. Measurement properties of four candidate primary outcomes, rates of recruitment, attrition, and data completeness were evaluated. RESULTS: Thirty-five participants (68.6% female) with median age (inter-quartile range [IQR]) 60.1 [49.4-68.4] years and disease duration 9.1 [4.0-16.2] months), were recruited and 23 (65.7%) completed 12-week follow-up. Intervention acceptability was excellent; 21/23 were confident that it could help and would recommend it; 22/23 indicated it made sense to them. Adherence was good, with a median [IQR] EARS score of 17/24 [12.5-22.5]. One serious adverse event that was unrelated to the study was reported. Twelve participants' and 9 therapists' interviews confirmed intervention acceptability, identified perceptions of benefit, but also highlighted some barriers to completion. Mean MITI scores for relational (4.38) and technical (4.19) aspects of motivational interviewing demonstrated good fidelity. The Foot Function Index disability subscale performed best in terms of theoretical consistency and was deemed most practical. CONCLUSION: GREAT Strides was viewed as acceptable by patients and therapists, and we observed high intervention fidelity, good patient adherence, and no safety concerns. A future trial to test the additional benefit of GREAT Strides to usual care will benefit from amended eligibility criteria, refinement of the intervention and strategies to ensure higher follow-up rates. The Foot Function Index disability subscale was identified as the primary outcome for the future trial. TRIAL REGISTRATION: ISRCTN14277030.

Physiotherapy informed by Acceptance and Commitment Therapy for chronic low back pain: A mixed-methods treatment fidelity evaluation.

OBJECTIVES: A randomized controlled trial of a new type of Physiotherapy informed by Acceptance and Commitment Therapy (PACT), found that it improved functioning in people with chronic low back pain compared to usual physiotherapy care. Fidelity evaluation is necessary to understand trial processes and outcomes. This study evaluated PACT treatment fidelity including delivery, receipt, and enactment. DESIGN: A mixed-methods study nested within a randomized controlled trial was conducted. METHODS: A total of 72 (20% of total) PACT treatment audio files were independently assessed by two raters, according to a novel framework developed to measure PACT treatment content adherence, therapeutic alliance, ACT competence, and treatment enactment. Interview transcripts from 19 trial participants randomized to PACT were analysed thematically for evidence of treatment receipt and enactment. RESULTS: PACT physiotherapists delivered treatment as intended with high content adherence and satisfactory therapeutic alliance, but ACT competence was low. Qualitative findings indicated participant receipt of 11/17 and enactment of 3/17 components; 89% (n = 17) and 47% (n = 9) of participants reported treatment receipt and enactment of at least one component, respectively. CONCLUSIONS: This mixed-methods study of PACT treatment demonstrated high fidelity reflecting treatment content delivery and receipt, and therapeutic alliance. There was some evidence of treatment enactment in participants with chronic low back pain. Low ACT competence could be addressed through additional support and adaptations to therapeutic processes for delivery by physiotherapists.

Using Intervention Mapping in the Systematic Development of a Behaviour Change Intervention to Enhance Exercise Adherence among People with Persistent Musculoskeletal Pain.

Purpose: This article describes the first four steps of the intervention mapping framework used to design a programme aimed at increasing adherence to prescribed exercise by people with persistent musculoskeletal pain. Method: In Step 1, a systematic review and qualitative study was completed to inform Step 2 and the identification of the Health Action Process Approach as an appropriate theoretical framework for establishing two programme objectives: enhancing self-management and providing tailored and accessible exercise instructions. Step 3 encompassed the selection of the programme methods, and the programme is described in Step 4. The resulting programme provides virtually delivered motivational interviewing and an app-based exercise programme to support individuals' adherence to exercise. Results: The resulting intervention was assessed in a proof-of-concept feasibility and acceptability study and was shown to be feasible and acceptable. Refinements to the programme included additional tailoring of the exercise app and modifying the motivational interviewing schedule. Conclusions: Using the intervention mapping approach enabled us to successfully develop an intervention aimed at supporting the development of self-management behaviours and addressing maladaptive beliefs as a means of enhancing individuals' adherence to exercise. Evaluation and implementation of the intervention should now be carried out.

L'étape trois englobait le choix de la méthodologie du programme, décrite à l'étape quatre. Le programme qui en découle comprend des entrevues motivationnelles virtuelles et un programme d'exercices fondé sur une application pour renforcer l'adhésion à l'exercice. Résultats : l'intervention obtenue, évaluée dans une étude de validation de la faisabilité et de l'acceptabilité, s'est révélée faisable et acceptable. Les améliorations au programme ont inclus de nouvelles adaptations à l'application d'exercices et des modifications au calendrier d'entrevues motivationnelles. Conclusion : grâce à la démarche de modélisation de l'intervention, il a été possible d'élaborer une intervention visant à promouvoir l'acquisition de comportements d'autogestion et à corriger des convictions mésadaptées pour accroître l'adhésion à l'exercice. Il reste maintenant à évaluer et à mettre en œuvre l'intervention.

Translation and Cross-Cultural Adaptation of the Exercise Adherence Rating Scale (EARS) into Danish.

The Exercise Adherence Rating Scale (EARS) is a self-administrated questionnaire designed to measure adherence to prescribed home-based exercises in a British population. In a Danish context, no reliable and valid questionnaires are available to measure exercise adherence. This study aimed to translate and cross-culturally adapt the EARS into Danish following international guidelines and to provide insights about construct validity in a Danish population with longstanding hip pain. The EARS was translated and cross-culturally adapted into Danish using a forward-backward method. The understanding and interpretability of the EARS were evaluated with semistructured interviews in 24 patients with longstanding hip pain due to hip dysplasia (22 females; median age 30 (IQR 24-37)). These patients were prescribed home-based exercises. Using Spearman's correlation, construct validity was evaluated by assessing if the Danish version of EARS was correlated with completed exercise sessions and self-reported pain and sport/recreation function. The EARS was translated and cross-culturally adapted into Danish following minor adjustments. The EARS was statistically significantly correlated to completed exercise sessions (p=0.005), self-reported pain (p=0.005), and sport/recreation function (p < 0.03). In patients with longstanding hip pain, the Danish EARS seems suitable to measure adherence to prescribed exercises; however, further evaluation of measurement properties may be needed.

Only two subscales of the Coping Strategies Questionnaire are culturally relevant for people with chronic low back pain in Nigerian Igbo populations: a cross-cultural adaptation and validation study.

BACKGROUND: Pain coping strategies are important in the chronicity of low back pain and the associated disability. However, their exact influence is unknown in many African contexts such as rural Nigeria due to lack of outcome instruments with which to measure them. This study aimed to cross-culturally adapt and psychometrically test the Coping Strategies Questionnaire (CSQ) in Igbo populations in Nigeria. METHODS: The CSQ was forward and back translated by clinical and non-clinical translators; evaluated by an expert review committee. The translated measure was piloted amongst twelve rural Nigerian dwellers with chronic low back pain (CLBP) using the think-aloud cognitive interviewing style. Internal consistency (Cronbach's alpha), test-retest reliability (intra-class correlation coefficient-ICC and Bland-Altman plot), and minimal detectable change were examined amongst 50 people with CLBP in rural and urban Nigerian populations. Construct validity was determined by assessing the correlations between the adapted CSQ and measures of disability, pain intensity, fear avoidance beliefs, and illness perceptions using Spearman's correlation analyses with 200 adults with CLBP in rural Nigeria. Exploratory factor analyses using Kaiser criterion (eigenvalue) and parallel analysis as methods for determining dimensionality were conducted with the same sample. RESULTS: Fourteen out of 42 items were routinely adopted in this population including all items of catastrophising subscale, and all but one item of praying and hoping subscale. Catastrophising and praying and hoping subscales had the highest Cronbach's alpha. All subscales had high ICCs with Bland-Altman plots that showed good agreement. All coping strategies were positively correlated with self-reported disability and pain intensity with catastrophising subscale having the highest values. Seven-factor and three-factor structures were produced with the Kaiser criterion and parallel analysis, with different items from the original CSQ, except for catastrophising. CONCLUSIONS: Catastrophising and praying and hoping may be the relevant coping strategies in this population. More culturally relevant measures of pain coping strategies that include adaptive coping strategies may need to be developed for African contexts such as rural Nigeria.

Development and validity assessment of a Japanese version of the Exercise Adherence Rating Scale in participants with musculoskeletal disorders.

BACKGROUND: Exercise adherence is important for achieving a long-term effect from musculoskeletal management. The Exercise Adherence Rating Scale (EARS), which was developed in 2017 as a patient reported outcome measure to assess exercise adherence in those with chronic low back pain in the UK, has demonstrated acceptable validity and reliability and is a robust measure of exercise adherence. This study aimed to undertake cross-cultural adaptation of the EARS into Japanese and investigate its structural validity in participants with musculoskeletal disorders. METHODS: The current study was composed of two phases, where a provisional Japanese version of the EARS was developed employing an international guideline for cross-cultural adaptation (Phase A), and structural validity was then evaluated using the Rasch analysis (Phase B). Participants with musculoskeletal disorders who have individualized home exercises prescribed by a physical therapist were recruited. RESULTS: In Phase A, the pilot testing was conducted twice because the initial testing detected some uncertainty revealed in comments from 17 participants (5 males and 12 females, 18-79 years of age) about which activities and exercises were supposed to be included. We therefore modified the draft by identifying a person who prescribed/recommended activities and exercises as per the Working Alliance Inventory. The second pilot testing using this draft recruited 30 participants (6 males and 24 females, 18-79 years of age), who provided no further comments, demonstrating the Japanese version of the EARS (EARS-J) had been successfully developed. In Phase B, data from 200 participants who completed the EARS-J (63 males and 127 females, mean ± SD of age = 53.6 ± 17.0) were analyzed using the Andrich's Rating Scale Model. Rasch statics indicated unidimensionality of the six items of the EARS-J. The Cronbach α was 0.77. Substantial ceiling effect (21.0%) was observed, with no floor effect (0.5%). CONCLUSIONS: A Japanese version of the EARS has been developed, which demonstrated acceptable structural validity with the evidence of unidimensionality in the Rasch analysis in Japanese people with musculoskeletal disorders who were prescribed individualized home exercises. However, there was a substantial ceiling effect and further studies are required to comprehensively establish validity and reliability of the EARS-J.

Detecting anxiety and depression among people with limited literacy living with chronic low back pain in Nigeria: adaptation and validation of the hospital anxiety and depression scale.

BACKGROUND: The Hospital Anxiety and Depression Scale (HADS) is one of the most popular measures of anxiety and depression. The original HADS is mostly used in Nigeria precluding people with limited literacy. This study aimed to cross-culturally adapt and psychometrically test the HADS for rural and urban Nigerian Igbo populations with chronic low back pain (CLBP) who have limited literacy. METHODS: The HADS was forward translated, back translated, and appraised. Face and content validity was ensured by pre-testing the translated measure among a convenience sample of twelve rural Nigerian dwellers with CLBP. Reliability utilising Cronbach's alpha, intraclass correlation coefficient, Bland-Altman plots and minimal detectable change were investigated amongst a convenience sample of 50 people living with CLBP in rural and urban Nigerian communities. Construct validity testing involving correlations between Igbo-HADS and Roland Morris Disability Questionnaire measuring self-reported back pain-specific disability, World Health Organisation Disability Assessment Schedule assessing generic self-reported disability, Fear Avoidance Beliefs Questionnaire measuring fear avoidance beliefs, and eleven-point box scale assessing pain intensity, and exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) among a random sample of 200 adults with CLBP in rural Nigerian communities were conducted. RESULTS: Idioms and colloquialisms were difficult to adapt. Internal consistency was good (α = 0.78) and acceptable (α = 0.67) for anxiety and depression subscales respectively. Intraclass correlation coefficients were very good (ICC ≃ 0.8) for both subscales. Minimal detectable change was 6.23 and 5.06 for anxiety and depression subscales respectively. The Igbo-HADS and the anxiety subscale had strong correlations (≃ 0.7) with generic self-reported disability; moderate correlations (≃ 0.5-0.6) with pain intensity, self-reported back pain-specific disability, and fear avoidance beliefs. The depression subscale had the lowest correlations (≃ 0.3-0.4) with these outcomes. The EFA produced a two-factor structure with cross-loading of items. The CFA showed poor fit indices for the EFA structure, the original two-factor structure, and one-factor structure. CONCLUSION: The HADS may not be suitable for assessing anxiety and depression, or emotional distress in this population due to difficulty achieving cross-cultural equivalence with western idioms; and the expression of emotional distress through somatisation in this culture.

Experiences of training and delivery of Physical therapy informed by Acceptance and Commitment Therapy (PACT): a longitudinal qualitative study.

OBJECTIVES: Physiotherapy informed by Acceptance and Commitment Therapy (PACT) is a novel intervention that is related to improved disability and functioning in people with chronic lowback pain. This study explored physiotherapists experiences over time of the PACT training programme and intervention delivery. DESIGN: A longitudinal qualitative study using semi-structured, in-depth, individual interviews at three time points was conducted. METHODS: A phenomenological approach underpinned the methods. Interviews followed topic-guides developed a priori. Transcribed interviews were coded inductively to generate themes. Data were member checked by participants and validated by two researchers. PARTICIPANTS: Eight clinical physiotherapists from three secondary care centres in the United Kingdom (n = 5 female; age, 24 to 44 years; duration of practice, 3 to 14 years) were included. RESULTS: Five themes emerged from the data. Experiential learning techniques were challenging but valued because they bridged theoretical principles and concepts with practice. Ongoing individual and group supervision was beneficial, but required tailoring and tapering. PACT delivery extended physiotherapy skills and practice, including techniques that acknowledged and addressed patient treatment expectations. With experience, participants desired greater flexibility and autonomy to tailor PACT delivery. CONCLUSIONS: PACT training and delivery were acceptable to physiotherapists. Existing skills were developed and additional, applicable approaches were provided that addressed psychosocial and behavioural aspects of chronic low back pain.

Effectiveness of web-based and mobile health interventions designed to enhance adherence to physical activity for people with inflammatory arthritis: a systematic review.

OBJECTIVE: The aim of this systematic review was to assess the evidence from randomized controlled trials (RCTs) and cohort studies for the effectiveness of digital interventions designed to enhance adherence to physical activity (PA) for people with inflammatory arthritis and describe the intervention content using established coding criteria. METHODS: Six electronic databases were searched for published and unpublished studies. Independent data extraction and quality assessment (Cochrane risk of bias II or ROBINS-I) were conducted by two reviewers. The primary outcome was self-reported adherence to PA post-intervention. Secondary outcomes included self-reported adherence to PA at other time points, level of PA or engagement with intervention at any follow-up time point. Intervention content was assessed using the Consensus on Exercise Reporting Template and the Behaviour Change Techniques Taxonomy version 1. RESULTS: From 11 136 citations, four moderate risk of bias studies (three RCTs and one cohort study) including 1160 participants with RA or JIA were identified. Owing to heterogeneity of outcomes, a narrative synthesis was conducted. Only one RCT reported a small between-group difference in adherence to PA [mean difference (95% CI) -0.46 (-0.82, -0.09)] in favour of the intervention. There were no between-group differences in any secondary outcomes. Interventions included between 3 and 11 behaviour change techniques but provided minimal information on exercise prescription. CONCLUSION: There is currently limited moderate-quality evidence available to provide confident evaluation of the effect of web-based and mobile health interventions on adherence to PA or level of PA post-intervention in people with inflammatory arthritis.

The Igbo Brief Illness Perceptions Questionnaire: A cross-cultural adaptation and validation study in Nigerian populations with chronic low back pain.

BACKGROUND: Illness perceptions predict chronic low back pain (CLBP) disability. This study cross-culturally adapted and validated the Igbo Brief Illness Perceptions Questionnaire (Igbo-BIPQ) in people with CLBP in rural/urban Nigeria. METHODS: A cross-cultural adaptation and validation of the Igbo-BIPQ was undertaken. The BIPQ was forward/back-translated by clinical/non-clinical translators. An expert review committee appraised the translations. The questionnaire was pre-tested on twelve rural Nigerian dwellers with CLBP. Internal consistency using Cronbach's alpha; test-retest reliability using intra-class correlation coefficient and Bland-Altman plot; and minimal detectable change were investigated amongst 50 people with CLBP in rural and urban Nigeria. Construct validity was determined by correlating the Igbo-BIPQ score with those of eleven-point box scale and Igbo Roland Morris Disability Questionnaire (Igbo-RMDQ) using Pearson's correlation analyses in 200 adults with CLBP in rural Nigeria. Ceiling and floor effects were investigated in both samples. RESULTS: Good face/content validity, internal consistency (α= 0.76) and intraclass correlation coefficient (ICC = 0.78); standard error of measurement and minimal detectable change of 5.44 and 15.08 respectively; moderate correlations with pain intensity and self-reported disability (r⩾ 0.4); no ceiling/floor effects were observed for Igbo-BIPQ. CONCLUSION: This study provides evidence of some aspects of validity and reliability of the Igbo-BIPQ.
