Implementing a workplace participatory approach to support working caregivers in balancing their work, private life and informal care: results of a process evaluation

BackgroundMany organizations are faced with growing numbers of employees who combine their jobs with informal caregiving responsibilities. To support working caregivers in maintaining a good balance between work, private life and informal care, a workplace participatory approach (PA) intervention was implemented in four Dutch organizations. This study’s aims were to evaluate the degree of PA implementation, contextual factors influencing implementation, and stakeholder experiences with the PA.MethodsA mixed methods process evaluation was conducted alongside a randomized controlled trial among three stakeholder groups: caregiving employees, their supervisors, and trained occupational professionals who acted as PA process facilitators. The implementation frameworks of Steckler and Linnan (2002) and Carrol et al. (2007) were applied to evaluate recruitment, reach, dosage, fidelity and context, as well as stakeholders’ satisfaction, experiences and perceived intervention outcomes. Data were collected after PA implementation (4–7 months) using questionnaires, semi-structured interviews, checklists and research logs.ResultsOf the 57 caregivers in the intervention group, 48 participated in the stepwise intervention. Among them, 20 (42%) completed all seven steps of the PA, and 30 (63%) involved their supervisors. PA implementation and supervisor involvement varied based on personal factors (e.g. a need for balance-related improvements; preference to keep caregiving private), interpersonal factors (e.g. caregiver-supervisor relationship quality), and organizational factors (high work demands; a supportive workplace culture for caregivers). Caregivers, supervisors, and process facilitators reported positive experiences with the PA, finding it valuable for addressing informal caregiving, receiving support and working on balance-related changes in multiple life domains. Some caregivers, however, needed more than the standard 3 PA meetings to identify key issues and implement solutions.ConclusionsStakeholders found the PA helpful in addressing working caregivers’ work-life balance, but PA implementation can be further stimulated by creating a supportive organizational culture in which it is encouraged and safe to discuss informal care. Moreover, to better support working caregivers in the long term, the PA should be viewed as an ongoing and iterative process taking into account their evolving balance and circumstances.Trial registrationCurrent Controlled Trials ISRCTN15363783 (Registration date 21 November 2022; Retrospectively registered).

Hvad kan indstillinger til Politikens Pædagogpris fortælle om udvikling af pædagogers faglighed?

In this article, the still unsettled development of pedagogues' professionalism is discussed, based on a recently completed study of three years' nominations for the national Politiken's Pedagogue Awards. First, the study itself is reviewed. We will then discuss the study's findings, drawing on two different theoretical perspectives. First, the study's results are understood in the light of Julia Evett's concepts of occupational versus organizational professionalism. Next, the same findings are viewed considering theories about the affective. Finally, the article discusses the study's highlighting of pedagogues' human, relational, affective qualities, which can be understood both as a historical relic from a non-professionalized time, as an expression of a slowdown in the management rationality, and finally as an expression of a broader affectation of society.

Translation, cross-cultural adaptation, and validation of the Spanish Evidence-Based Practice Confidence (EPIC) scale in occupational therapy students and professionals

BackgroundAssessing self-efficacy in evidence-based practice (EBP) is crucial for identifying training needs, evaluating the effectiveness of educational programs, and assessing the overall application confidence of EBP in healthcare professions, including occupational therapy (OT). Thus, the objectives of this study were to cross-culturally adapt the Evidence-Based Practice Confidence Scale (EPIC) for Spanish-speaking OT students and professionals and to evaluate its internal consistency, test–retest reliability, and construct validity.MethodsA professional translation and cross-cultural adaptation of the EPIC was developed, including a pilot study that resulted in the EPIC Spanish version. A total of 260 OT students and 202 professionals completed the Spanish EPIC at baseline, with 177 (68.1%) students and 129 (63.9%) professionals participating in the test–retest reliability assessment two weeks later. The EPIC’s internal consistency was evaluated using Cronbach’s alpha. Test–retest reliability was assessed using Spearman’s correlations and intra-class correlations (ICC). Known-groups validity hypothesis based on participants' roles (students, diploma/bachelor’s, master’s, and doctorate) was explored using ANOVA. Finally, an exploratory factor analysis with oblique Promax rotation was conducted to examine the EPIC factor structure.ResultsCronbach’s alpha for the total EPIC score was excellent in both OT professionals (α = 0.91) and students (α = 0.90). For OT students, Spearman’s correlation was 0.67 (p < 0.001) for the total score, and the ICC was 0.66 (95%CI 0.57–0.73). Conversely, for OT professionals, test–retest reliability showed a Spearman’s correlation of 0.87 (p < 0.001) for the total score, and the ICC was 0.87 (95%CI 0.81–0.90). The highest scores were observed in professionals with a doctorate followed by those with a master’s degree (p < 0.001). The exploratory factor analysis yielded a 3-factor solution that explained 71% of the observed variance, with item-level loadings ≥ 0.35.ConclusionsThe EPIC scale showed excellent internal consistency, strong test–retest reliability, and adequate construct validity for evaluating EBP self-efficacy among Spanish-speaking OT professionals using the total score. However, test–retest reliability was moderate among Spanish-speaking OT students, indicating that changes in EBP confidence assessed with the EPIC scale in this group should be interpreted with caution.

Insights from the "Acoustics Workshop in Educational Buildings" by Turkish Acoustical Society

This paper focuses on "Acoustics Workshop in Educational Buildings" organized by the Turkish Acoustical Society as part of International Noise Awareness Day 2023 Activities. The workshop brought together 34 participants, including designers, acoustic experts, teachers, and health and occupational safety professionals. Through interdisciplinary discussions, participants identified and prioritized acoustic problems, expectations and requirements for educational buildings, focusing on improving the quality of education. The workshop unfolded in two stages: firstly, participants were grouped by profession to identify primary acoustic challenges. Subsequently, multi-disciplinary teams collaboratively developed mitigation strategies to address these challenges. The results revealed profession-specific insights into main acoustic issues and proposed actionable solutions. This paper specifically provides insights into the use of qualitative content analysis to have a deeper understanding of different professions, people's experiences, behavior and priorities in relation to acoustics in school.

“Risk Hunting” as a competence resource in the training of occupational safety professionals

The article discusses the use of project-based learning in the training of experts in Technosphere Safety, particularly occupational safety and health professionals. For these categories, the main competence is obtaining knowledge of assessing working conditions, identifying hazards and occupational risks for the development and implementation of measures aimed to eliminate them. The article presents the results of the “Risk Hunting” project, including occupational risk assessment cards, hazard registers, projects of occupational risk reduction measures, labor protection competitions, the Occupational Safety Day presentation, and the training for Irkutsk National Research Technical University department heads. The article distinguishes between two types of educational results: development of competencies required for labor protection professionals and gaining experience in self-organization and self-education. Project-based learning is aimed at solving specific tasks and gaining professional experience, which needs to be developed and improved.

Evaluation of a self-monitoring protocol for assessing soot and polycyclic aromatic hydrocarbon exposure among chimney sweeps.

Traditional methods for measuring chemical exposure have challenges in terms of obtaining sufficient data; therefore, improved methods for better assessing occupational exposure are needed. One possible approach to mitigate these challenges is to use self-monitoring methods such as sensors, diaries, or biomarkers. In the present study, a self-monitored method for measuring soot exposure, which included real-time air monitoring, a work diary, and the collection of urine samples, was evaluated. To validate the method, exposure measurements during the workday and diary entries were compared with velocities calculated from GPS tracking and the expected polycyclic aromatic hydrocarbon (PAH) metabolite patterns in urine. The method was applied with chimney sweeps, an occupational group at a high risk of many severe health outcomes and for whom effective control measures for reducing exposure are needed. In the study, 20 chimney sweeps followed a self-monitoring protocol for 8 consecutive workdays. Personal exposure to soot was measured as black carbon (BC) using micro-aethalometers. A diary was used to record the work tasks performed, and urine samples were collected and analysed for PAH metabolites. From the expected 160 full day measurements, 146 (91%) BC measurements and 149 (93%) diaries were collected. From the expected 320 urine samples, 304 (95%) were collected. The tasks noted in the diaries overlapped with information obtained from the GPS tracking of the chimney sweeps, which covered 96% of the measurement time. The PAH metabolites in urine increased during the work week. Factors believed to have positively influenced the sample collection and task documentation were the highly motivated participants and the continuous presence of trained occupational hygiene professionals during the planning of the study and throughout the measurement stage, during which they were available to inform, instruct, and address questions. In conclusion, the self-monitored protocol used in this study with chimney sweeps is a valuable and valid method that can be used to collect larger numbers of samples. This is especially valuable for occupations in which the employees are working independently and the exposure is difficult to monitor with traditional occupational hygiene methods.

Preventing Surgeon Work-Related Musculoskeletal Disorders: A Pilot Study of the Comprehensive Operating Room Ergonomics (CORE) Program.

Work-related musculoskeletal disorders (WMSDs) among surgeons are markedly increasing. Several proposed interventions to reduce WMSDs among surgeons have been studied, but few follow an occupational therapy-oriented approach addressing biomechanical, psychophysical, and psychosocial risk factors. To design, implement, and assess the potential of the Comprehensive Operating Room Ergonomics (CORE) program for surgeons, a holistic evidence-based ergonomics and wellness intervention grounded in occupational therapy principles. Mixed-methods pilot study with the quantitative strand embedded in the qualitative strand. University-affiliated hospital. Six laparoscopic surgeons. CORE program outcomes were assessed using qualitative and quantitative data to indicate changes in posture, physical discomfort, sense of wellness, and operating room (OR) ergonomic performance. The Rapid Upper Limb Assessment (RULA) was used to quantify surgeons' WMSD risk level before and after intervention. There were 12 baseline observations (two for each participant), and two or three post-CORE implementation observations. A statistically significant difference, F(1, 6) = 8.57, p = .03, was found between pre- and post-occupational therapy intervention RULA scores. Thematic analysis of surgeon feedback, which was overwhelmingly positive, identified five themes: postural alignment, areas of commonly reported physical pain or discomfort, setup of the OR environment, surgical ergonomics training, and ergonomics in everyday life. The CORE program effectively decreased ergonomic risk factors to optimize surgeons' occupational performance in the OR. This study demonstrates a potential solution to how occupational therapists can holistically support surgeons and health care providers who are at risk for WMSDs. Plain-Language Summary: By 2025, a surgeon shortage is expected, partly because of the increase in surgeons' work-related musculoskeletal disorders, which affect their health and job continuity. This pilot study shows that the Comprehensive Operating Room Ergonomics program effectively addresses these problems. The study also serves as a framework for occupational therapy professionals to work with health care providers on ergonomics, benefiting population health. Results suggest that this approach could enhance surgeons' work conditions, supporting the American Occupational Therapy Association's Vision 2025 to improve health and quality of life.

Factors contributing to frailty in institutionalized older adults: a multi-institutional cross-sectional study

To reveal the characteristics and the oral function of institutionalized frail older adults and the factors contributing to frailty. This multicenter, cross-sectional study included 214 patients. A questionnaire was administered to registered dietitians from these institutions. Sex, age, height, weight, grip strength, calf circumference, level of care need, FRAIL-NH, MNA® -SF, dysphagia, food form and water thickening, number of medications, major diseases, comorbidities, independence in daily living of older people with dementia, use of medication with dry mouth, nutritional care issues (malnutrition-related problems) by multiple occupations in Nutrition and Eating Swallowing Screening, Assessment and Monitoring, and nine oral-related items were evaluated. One hundred six patients (49.5%) were classified as frail, 75% of the patients were women, and the mean BMI was 19.7 kg/m2. Older adults with frailty were characterized by high care needs, malnutrition, multiple comorbidities, multiple medications, eating and swallowing disorders, the requirement of feeding assistance, and the need to adjust the shape of meals and fluids. The multivariable OR (95%CI) for "choking and residue problems" was 1.81 (1.20-2.73), while that for "dietary concentration problems" was 4.28 (2.10-8.74). Caregivers must maintain posture and provide meal assistance. Professionals in various occupations must adjust the proper food form and medication content. Meal times must be examined in consideration of the times at which drugs will be most effective. Oral care must be provided, and an environment must be created to help the subject concentrate. Focusing on problems of choking, residue, and concentration on meals is expected to improve frailty, aspiration pneumonia, and the prognosis of institutionalized older adults.

Principals’ sense-making and sense-giving of their professional role tensions: School leaders’ professionalism and creative mediation strategies during Covid-19 crisis

School principals are located at the interface between competing demands by a wide spectrum of stakeholders leading to tensions and ambiguities in their role. Understanding principals’ role tensions within organizational and occupational professionalism during Covid-19 crisis is of considerable importance for improving the capacity of school leadership. This qualitative study examines Israeli principals’ considerations and creative mediation strategies while facing competing accountabilities via the theoretical framework of sense-making and sense-giving in times of crisis. Using a collective case study design, data were collected via semi-structured interviews with 16 elementary and high school principals and policy documents, and analyzed thematically via ATLAS.ti software. The analysis surfaced three strategies and two considerations: (1) school leaders’ sense-making processes yielding protective mediation strategies based on retaining moral discretion; and (2) school leaders’ sense-giving processes transferring collaborative and contrived mediation strategies based on establishing the school's moral-professional cultural orientation. The contribution of this study to the research literature suggests contrived mediation as an innovative school leaders’ strategy. We provide practical implications within training and professional development programs for school leaders advocating principalship mentoring valuing uniqueness to experienced and novice principals.

Occupational Exposure to Aerosolized Human Papillomavirus: Assessing and Addressing Perceptions of and Barriers to Vaccination of at-Risk Health Care Workers.

This study aimed to assess current vaccination rates among health care workers at risk for occupational human papillomavirus (HPV) exposure and explore factors that influence decisions about HPV vaccination. Using a mixed-methods design, this study included a questionnaire and qualitative focus groups. The study took place at an academic medical center. Participants were 37 health care professionals in occupations at risk for workplace HPV exposure. The primary qualitative outcome measured was HPV vaccination status. The primary qualitative outcomes assessed were perceptions of occupational HPV exposure risk, protective measures, and HPV vaccination. Most participants were female (86.5%, n = 32) and younger than 35 years (51.4%; n = 19) and therefore would have been eligible to receive the HPV vaccine series as a teenager or young adult. Nearly two-thirds (67.6%; n = 25) of participants had received the HPV vaccine; of those, half were vaccinated as teenagers (52%; n = 13). One-third (n = 4) of those vaccinated as adults reported vaccination due to workplace HPV exposure. Focus groups revealed themes consistent with the Health Belief Model. Most participants recognized their risk of aerosolized HPV exposure in the workplace but felt uneducated about occupational exposure risk and protective measures. Many participants recognized risk of exposure through surgical smoke but perceived that risk was stratified by medical specialty, proximity to surgical field, and personal protective equipment use. Many participants had some level of concern for head and neck lesions with exposure to aerosolized HPV. Most participants recognized the need to protect themselves against workplace HPV exposure. Those who were vaccinated felt that they were better protected against HPV exposure. Almost all participants said that they had not received formal education on workplace HPV exposure risk. Many participants voiced perceived barriers to HPV vaccination. Health care workers encounter the HPV virus in a myriad of fields and procedures. Our mixed-methods study demonstrated that at-risk health care workers feel uninformed about their risk of HPV exposure in the workplace, availability of HPV vaccination, and appropriate protective equipment recommendations.

The Perceptions of Different Disciplines on Early Childhood Interprofessional Teams Involving Occupational Therapy Services

This phenomenological study was conducted to explore how professionals identify the roles of occupational therapy practitioners and other pediatric professionals on early childhood interprofessional teams. The use of surveys and interviews revealed three themes: 1) the role of occupational therapy encompasses more than what is perceived to be their role, 2) collaboration must be initiated, as it can be influenced by the setting, and 3) different professionals have the shared goal of promoting child health outcomes, but conflict can arise during collaboration. It was recognized that early childhood professionals would like to collaborate more with each member on the interprofessional team, but external influences and different settings for providing early childhood services may impact the ability to collaborate. This study discusses implications for occupational therapy professionals working in early childhood and the possibilities for future research.

Towards person-centred work-focused healthcare for people with cardiovascular disease: a qualitative exploration of patients’ experiences and needs

Purpose To explore the experiences and needs concerning work-focused healthcare of patients experiencing problems with work participation due to cardiovascular disease based on all facets of person-centred care. Methods Nineteen patients who experienced or continue to experience problems with work participation due to cardiovascular disease participated in semi-structured interviews preceded by preparatory written assignments. The transcripts were analysed by means of directed qualitative content analysis. Adapted principles of the Picker Institute for Person-Centred Care provided a template for the analysis. Results 28 experiences and needs emerged and were grouped into the eight principles for person-centred work-focused healthcare. Randomly presenting one theme for each of the eight principles, the themes included: (1) frequent encounters with occupational healthcare professionals; (2) substantive work-related advice; (3) transparency in communication; (4) support for family; (5) information provision on the work-focused healthcare process; (6) personal control during the process; (7) empathy for the personal situation; and (8) tailored work-focused support. Conclusions The identified experiences and needs for work-focused healthcare of patients experiencing problems with work participation due to cardiovascular disease clearly indicate the need to improve the delivery of person-centred work-focused healthcare to better meet the individual needs of patients.

Occupational therapy practitioners’ experiences with interprofessional collaborative practice

ABSTRACT Although occupational therapists engage as part of interprofessional healthcare teams, explicit investigation into their experiences of interprofessional collaborative practice (IPCP) has not been explored. This study evaluated occupational therapists in the United States experiences of IPCP with additional inquiry into which healthcare professionals occupational therapy practitioners interact with and how they engage in collaboration, during IPCP. An exploratory cross-sectional study was conducted using an online survey; 142 occupational therapy practitioners responded. Quantitative data were analyzed using descriptive and bivariate analyses; open-ended responses underwent consensual qualitative analysis. Participants reported most often engaging in IPCP with physical therapists, speech-language pathologists, nurses, physicians, and case managers, although variations in the top five professions were evident between practice settings. In addition, 82% of the respondents reported either feeling prepared or very prepared for IPCP after completing their pre-licensed educational programs. Two qualitative themes have emerged to describe key education-oriented and practice-oriented interprofessional experiences. To further enhance engagement in and preparedness for IPCP, occupational therapy professionals, and students may benefit from interprofessional training that involves the professions most often encountered during clinical practice. This type of learning could foster an understanding of communication and teamwork, thus enhancing readiness to participate in the IPCP team upon transition to practice.

Occupational Therapy’s Opportunity to Impact Care at the End of Life

Navigating and managing the end of life can be difficult. The focus of occupational therapy in care at the end of life is to aid the patient and caregiver through these challenges by facilitating improved safety, comfort, and quality of life through the participation in meaningful occupations. Despite the ways that occupational therapy benefits these patients, occupational therapy involvement in care at the end of life is misunderstood, under-researched, and underutilized. There is a general lack of awareness regarding this topic and a stigma that occupational therapy focuses only on rehabilitation and therefore does not belong in care at the end of life. To combat these issues, there needs to be additional education and training for all healthcare professionals, including occupational therapy practitioners, about occupational therapy’s role in care at the end of life. Occupational therapy professionals in this area of practice must strive to educate others and advocate for their role to improve the understanding of this practice area and thus positively impact more patients and families.

Towards the measurement of stereotype threat: scale development and validation

Purpose The purpose of the study is to develop a valid measure of stereotype threat. Design/methodology/approach A convenience sample of 2,900 respondents from different occupational sectors, including managers, engineers and health-care professionals, was used for the present study. The data were collected from various government and private organizations in North India. The questionnaire survey was administered in three phases. During the first phase, 800 questionnaires were circulated, followed by 1,200 questionnaires in the second phase, and the third phase involves 900 questionnaires. The data were analysed using exploratory factor analysis, confirmatory factor analysis and structural equation modelling. Findings The results indicate nine dimensions, namely, occupational identification, occupational stigma consciousness, gender identification, gender stigma consciousness, religion identification, religion stigma consciousness, caste identification, caste stigma consciousness and negative effect of stereotype threat. The study ensures the reliability and validity of the stereotype threat scale. The measure also fulfils the assumptions of nomological validity. Originality/value To the best of the authors’ knowledge, the study is the first of its kind to develop and validate the stereotype threat scale adhering to scale development procedures.

ChatGPT in Occupational Medicine: A Comparative Study with Human Experts.

The objective of this study is to evaluate ChatGPT's accuracy and reliability in answering complex medical questions related to occupational health and explore the implications and limitations of AI in occupational health medicine. The study also provides recommendations for future research in this area and informs decision-makers about AI's impact on healthcare. A group of physicians was enlisted to create a dataset of questions and answers on Italian occupational medicine legislation. The physicians were divided into two teams, and each team member was assigned a different subject area. ChatGPT was used to generate answers for each question, with/without legislative context. The two teams then evaluated human and AI-generated answers blind, with each group reviewing the other group's work. Occupational physicians outperformed ChatGPT in generating accurate questions on a 5-point Likert score, while the answers provided by ChatGPT with access to legislative texts were comparable to those of professional doctors. Still, we found that users tend to prefer answers generated by humans, indicating that while ChatGPT is useful, users still value the opinions of occupational medicine professionals.

Developing the First Digital Occupational Therapy Dictionary Worldwide: A Promising Mobile Application Model for Occupational Therapy Service Providers and Recipients.

The purpose of this study was to develop the first English-Arabic occupational therapy dictionary mobile application that could be used by occupational therapy service providers and recipients and help fill the gap in understanding and communicating occupational therapy services. Google Play Store and App Store application stores were searched first to identify any current electronic occupational therapy dictionary. While developing the dictionary concept and structure, end users' needs, language, and culture were taken into consideration applying a user-friendly design, functionalities, and an easy-to-understand language with illustrative visual representations. Our search for currently available electronic occupational therapy dictionaries did not identify any mobile application on the official application stores for iPhone and Android. As a result, a conceptual model was created to develop a mobile application aiming to develop a comprehensive and user-friendly mobile electronic dictionary with over 2400 scientific terms translated and annotated from English to Arabic, more than 350 illustrative pictures, and special features to assist occupational therapy professionals and occupational therapy services recipients in looking up and understanding terminology used in rehabilitation and occupational therapy in the most convenient, fastest, and easiest way possible. The occupational therapy dictionary mobile application has helped create a unified terminology and a common language of shared understanding, proved to be a helpful tool of communicating important messages between Arab occupational therapy professionals and community members through providing an easy access to up-to-date comprehensive English-Arabic lexicography in occupational therapy. It has become the first digital occupational therapy dictionary worldwide and has been made available for everyone to download from Google Play and App Store on their smartphones, computers, or tablets free of charge. Further research is urgently needed for quality improvement and to further enrich Arabic content in occupational therapy through developing evidence-based mobile tools to be used in occupational therapy practice by Arabic-speaking population.

Preparing for and Responding to the Current Mental Health Tsunami: Embracing Mary Reilly's Call to Action.

Although occupational therapy has its roots in mental health practice, the profession has not been able to adequately and consistently address mental health issues that face society today. As we continue to experience both the protracted coronavirus disease 2019 pandemic and political and social unrest, occupational therapy professionals must take action at individual, state, and national levels to assist in mitigating the current mental health tsunami and improving a fractured mental health care system. In this column, we define and explore issues facing the mental health care system and the different roles and perspectives that are relevant to occupational therapy professionals. Recommendations for the future are provided: actions that can be facilitated at the individual level, in practice, education, and research; at the state level, through state organizations and strategic partnerships; and at the national level, through the American Occupational Therapy Association and other means of advocacy. We want to honor Mary Reilly's vision that occupational therapy become one of the greatest ideas of our time.

“Nós buscamos transformação social”: narrativas de experiências de profissionais da terapia ocupacional social

Abstract Introduction Social injustices and inequalities have become more prevalent worldwide, in recognition of this, occupational therapy and occupational science adopted and developed a social, transformative and critical practices. This has become more prevalent in Brazil, where social occupational therapy professionals, grounded in critical and ethical-political standpoints, have been working with groups and populations to enable justice and rights. Objective This study aims to understand the social occupational therapy professionals’ reasoning regarding their practices, and since Social Occupational Therapy (SOT) is a practice from the Global South, we draw some possible links between occupational science and social occupational therapy, which can contribute to the social relevance and impact of the occupational therapy profession in both Western and developing countries. Method This study utilized Polkinghorne's interpretive, narrative approach to interviewing 5 social occupational therapists from different regions and work environments in Brazil. Results The participants narrative interviews revealed how social occupational therapists focus on the social dimension of their professional reasoning. They have come to embrace a critical perspective, acknowledging the socio-political context of the communities and groups of people they work with, often in situations of vulnerability. This can be understood by the growing discussion of the role of occupational science as critical and socially responsive practice. Conclusion These findings can facilitate an intercultural dialogue with other frameworks that also advocate for social transformative work and collective action.

Risk factors for work-related musculoskeletal disorders among workers in Brazil: A structural equation model approach

This study aimed to verify the direct and indirect influence of risk factors on the symptoms of WMSDs in the thigh, leg, and foot among workers in the inner regions of Brazil. Research tested a structural equation model (SEM) that describes hypothetical relationships between risk factors and WMSDs. Questionnaires were used to collect data on sociodemographic, occupational, biomechanical, and psychosocial factors, and pain symptoms about 420 workers. The results showed that different factors directly affect the thigh, leg, and foot. Maintaining the lower limbs in uncomfortable positions increases the chances of developing WMSDs in the thigh (β = 0.219; p-value <0.001), leg (β = 0.223; p-value <0.001), and foot (β = 0.158; p-value <0.01). Most psychosocial factors attenuate psychosocial stress, which in turn directly alleviates WMSD symptoms in the thigh (β = −0.502; p-value <0.001), leg (β = −0.315; p-value <0.01), and foot (β = −0.246; p-value <0.01). Factors were also found to uniquely affect aspects such as “another job” (β = −0.246; p-value <0.01) in the leg and effort (β = 0.146; p-value <0.05) in the foot. It was concluded that multiple factors influence the development of WMSDs in the lower limbs. These findings contribute to the existing knowledge on the causes of WMSDs and can help improve working conditions for the population under study. Therefore, managers and health, ergonomics, and occupational safety professionals can use the findings to develop more precise strategies to reduce the impacts of WMSDs on workers.
