Hearing and Functioning in Everyday Life Questionnaire: Development and Validation of an ICF-Based Instrument.

OBJECTIVES: Self-assessment instruments are commonly used in audiological rehabilitation. However, several studies highlight the lack of multidimensionality in existing outcome measures, with the consequence that they only partially capture aspects of functioning in everyday life for people living with hearing loss. This study aimed to develop and investigate the content validity of a self-assessment instrument based on the validated Brief International Classification of Functioning, Disability, and Health Core Set for Hearing Loss. DESIGN: The design was a two-part instrument development study. The first part focused on the item-generation process of the instrument, named the Hearing and Functioning in Everyday Life Questionnaire (HFEQ) during an experts' workshop. The second part focused on international content validation of the instrument using group interviews. Strategic sampling was used and 30 adults with hearing loss from India, South Africa, and the United States participated in the group interviews. RESULTS: The expert's workshop resulted in the first version of the HFEQ containing 30 items. The results from group interviews show that the content of the HFEQ was considered to be valid concerning its relevance, comprehensiveness, and comprehensibility. A majority (73%) of the HFEQ items were perceived by the participants as relevant and easy to comprehend. For the remaining 27% of the items, the content was perceived to be relevant in all countries, but some terms and expressions were reported to require rewording or clearer examples. These modifications will be made in the next step of the development process. CONCLUSION: Content validation of the HFEQ demonstrates promising results, with participants perceiving the content as relevant and comprehensible. Further psychometric validation is required to investigate other psychometric properties, such as construct validity and reliability. The HFEQ has the potential to become a valuable new instrument for assessing everyday functioning in people with hearing loss in audiological rehabilitation and in research.

ICF Core Sets for the assessment of functioning of adults with cerebral palsy.

AIM: To report on the results of the online international consensus process to develop the comprehensive and brief International Classification of Functioning, Disability and Health (ICF) Core Sets for adults with cerebral palsy (CP). METHOD: An online iterative decision-making and consensus process involved 25 experts, including clinicians and researchers working with adults with CP, an adult with CP, and the parents of adults with CP from all six regions of the World Health Organization. The most relevant categories were selected from a list of 154 unique second-level candidate categories to develop the ICF Core Sets for adults with CP. This list resulted from evidence gathered during four preparatory studies, that is, a systematic literature review, a qualitative study, an expert survey, and an empirical study. RESULTS: The consensus process resulted in the comprehensive ICF Core Set containing 120 second-level ICF categories: 33 body functions; eight body structures; 50 activities and participation; and 29 environmental factors, from which the most essential categories, 33 in total, were selected for the brief ICF Core Set. For body functions, most of the categories were mental functions and neuromusculoskeletal and movement-related functions. Body structures were mostly related to movement. All the chapters of the activities and participation component were represented, with mobility and self-care as the most frequently covered chapters. For environmental factors, most of the categories addressed products and technology and services, systems, and policies. INTERPRETATION: The comprehensive and brief ICF Core Sets for adults with CP were created using a new online version of an established ICF Core Set consensus process. These Core Sets complement the age-specific ICF Core Sets for children and young people with CP and will promote standardized data collection worldwide.

Development of a clinical tool for rating the body function categories of the ICF generic-30/rehabilitation set in Japanese rehabilitation practice and examination of its interrater reliability.

BACKGROUND: The International Classification of Functioning, Disability, and Health (ICF) Generic-30 (Rehabilitation) Set is a tool used to assess the functioning of a clinical population in rehabilitation. The ICF Generic-30 consists of nine ICF categories from the component "body functions" and 21 from the component "activities and participation". This study aimed to develop a rating reference guide for the nine body function categories of the ICF Generic-30 Set using a predefined, structured process and to examine the interrater reliability of the ratings using the rating reference guide. METHODS: The development of the first version of the rating reference guide involved the following steps: (1) a trial of rating patients by several raters; (2) cognitive interviews with each rater to analyze the thought process involved in each rating; (3) the drafting of the rating reference guide by a multidisciplinary panel; and (4) a review by ICF specialists to confirm consistency with the ICF. Subsequently, we conducted a first field test to gain insight into the use of the guide in practice. The reference guide was modified based on the raters' feedback in the field test, and an inter-rater reliability test was conducted thereafter. Interrater agreement was evaluated using weighted kappa statistics with linear weights. RESULTS: The first version of the rating reference guide was successfully developed and tested. The weighted kappa coefficient in the field testing ranged from 0.25 to 0.92. The interrater reliability testing of the rating reference guide modified based on the field test results yielded an improved weighted kappa coefficient ranging from 0.53 to 0.78. Relative improvements in the weighted kappa coefficients were observed in seven out of the nine categories. Consequently, seven out of nine categories were found to have a weighted kappa coefficient of 0.61 or higher. CONCLUSIONS: In this study, we developed and modified a rating reference guide for the body function categories of the ICF Generic-30 Set. The interrater reliability test using the final version of the rating reference guide showed moderate to substantial interrater agreement, which encouraged the use of the ICF in rehabilitation practice.

Development of an ICF Core Set for adults with cerebral palsy: capturing their perspective on functioning.

AIM: To examine the most relevant aspects of functioning of adults with cerebral palsy (CP) from their perspective, in order to develop an International Classification of Functioning, Disability and Health (ICF) Core Set for adults with CP. METHOD: We conducted six focus group discussions with adults with CP without intellectual disability and seven interviews with adults with CP with intellectual disability and caregivers, addressing all ICF components. Meaningful concepts were identified from verbatim transcripts and linked to ICF categories by two independent researchers. RESULTS: In total, 31 adults with CP without intellectual disability (mean [SD] age 46y 1mo [14y 1mo]; 20 females, 11 males; Gross Motor Function Classification System [GMFCS] levels I-IV) and seven adults with CP and intellectual disability (mean [SD] age 25y 8mo [6y 8mo]; four females, three males; GMFCS levels III-V) participated. We identified 132 unique second-level categories: 47 body functions, seven body structures, 43 activities and participation, and 35 environmental factors. The most frequently mentioned categories were emotional function, pain, muscle tone function, support of family, products and technology, and health services. INTERPRETATION: Adults with CP experienced problems in a broad range of body functions and activities and indicated the importance of environmental factors for functioning. The identified categories will be added to the list of candidate items to reach consensus on an ICF Core Set for adults with CP. What this paper adds Including the lived experience is crucial for fully understanding functioning of adults with cerebral palsy (CP). Adults with CP perceive environmental factors as essential elements for everyday functioning. Adults with intellectual disability should be considered as a group with specific problems.

Supporting the clinical use of the ICF in Japan - development of the Japanese version of the simple, intuitive descriptions for the ICF Generic-30 set, its operationalization through a rating reference guide, and interrater reliability study.

BACKGROUND: The World Health Organization developed the International Classification of Functioning, Disability, and Health (ICF) in 2001 and has been in the process of implementing it in clinics since then. Current international efforts to implement ICF in rehabilitation clinics include the implementation of ICF Core Sets and the development of simple, intuitive descriptions for the ICF Generic-30 Set (also called Rehabilitation Set). The present study was designed to operationalize these ICF tools for clinical practice in Japan. This work included 1) the development of the Japanese version of the simple, intuitive descriptions for the ICF Generic-30 Set, 2) the development of a rating reference guide for Activity and Participation categories, and 3) the examination of the interrater reliability of rating Activity and Participation categories. METHODS: The Japanese version of the simple, intuitive descriptions for the ICF Generic-30 Set was developed following the process employed to develop the Chinese and Italian versions. For further operationalization of this ICF Set in practice, a rating reference guide was developed. The development of the rating reference guide involved the following steps: 1) a trial of rating patients by several raters, 2) cognitive interviewing of the raters to analyse the thinking process involved in rating, 3) drafting of the rating reference guide, and 4) review by ICF specialists to confirm consistency with the original ICF concepts. After the rating reference guide was developed, interrater reliability of the rating with the reference guide was determined. Interrater reliability was examined using weighted kappa statistics with linear weight. RESULTS: Through the pre-defined process, the Japanese version of the simple, intuitive descriptions for 30 categories of the ICF Generic-30 Set and the rating reference guides for 21 Activity and Participation categories were successfully developed. The weighted kappa statistics ranged from 0.61 to 0.85, showing substantial to excellent agreement of the ratings between raters. CONCLUSIONS: The present study demonstrates that ICF categories can be translated into clinical practice. Collaboration between clinicians and researchers would further enhance the implementation of the ICF in Japan.

Outcomes in adults with cerebral palsy: systematic review using the International Classification of Functioning, Disability and Health.

AIM: In the context of the development of an International Classification of Functioning, Disability and Health (ICF) Core Set for adults with cerebral palsy (CP), this systematic review sought to identify the outcome measures used in studies on adults with CP, to examine their content using the ICF as a reference, and to demonstrate the most studied areas in this population. METHOD: Embase, MEDLINE, Web of Science, PsycINFO, CINAHL, Cochrane, and Google Scholar were searched for studies on adults with CP published between 2000 and 2017. Meaningful concepts of commonly used outcome measures were linked to the ICF, and frequencies of resultant ICF categories were explored. RESULTS: In 274 included articles, 332 outcome measures were identified of which 155 were commonly used. In total, 4409 meaningful concepts were linked to the ICF. The component 'Activities and participation' included the most frequent categories, followed by 'Body functions'. The most frequent categories were b280 'Sensation of pain' (37.6%), d450 'Walking' (33.3%), and d850 'Remunerative employment' (27.5%). INTERPRETATION: The broad range of ICF categories identified in this systematic review emphasizes the heterogeneity of functioning and disability in adults with CP. The current results specifically reflect the researchers' perspective and will serve as candidate categories to consider in the development of an ICF Core Set for adults with CP. WHAT THIS PAPER ADDS: Outcomes studied in adults with cerebral palsy are captured in varying International Classification of Functioning, Disability and Health (ICF) categories. Activities and participation were studied more frequently than body functions and structures. Mobility, employment, and self-care were most frequent within ICF's 'Activities and participation' component. Pain and neuromusculoskeletal and movement-related functions were most frequent within 'Body functions'.

Standardised assessment of functioning in ADHD: consensus on the ICF Core Sets for ADHD.

Attention-deficit/hyperactivity disorder (ADHD) is associated with significant impairments in social, educational, and occupational functioning, as well as specific strengths. Currently, there is no internationally accepted standard to assess the functioning of individuals with ADHD. WHO's International Classification of Functioning, Disability and Health-child and youth version (ICF) can serve as a conceptual basis for such a standard. The objective of this study is to develop a comprehensive, a common brief, and three age-appropriate brief ICF Core Sets for ADHD. Using a standardised methodology, four international preparatory studies generated 132 second-level ICF candidate categories that served as the basis for developing ADHD Core Sets. Using these categories and following an iterative consensus process, 20 ADHD experts from nine professional disciplines and representing all six WHO regions selected the most relevant categories to constitute the ADHD Core Sets. The consensus process resulted in 72 second-level ICF categories forming the comprehensive ICF Core Set-these represented 8 body functions, 35 activities and participation, and 29 environmental categories. A Common Brief Core Set that included 38 categories was also defined. Age-specific brief Core Sets included a 47 category preschool version for 0-5 years old, a 55 category school-age version for 6-16 years old, and a 52 category version for older adolescents and adults 17 years old and above. The ICF Core Sets for ADHD mark a milestone toward an internationally standardised functional assessment of ADHD across the lifespan, and across educational, administrative, clinical, and research settings.

An international qualitative study of ability and disability in ADHD using the WHO-ICF framework.

This is the third in a series of four cross-cultural empirical studies designed to develop International Classification of Functioning, Disability and Health (ICF, and Children and Youth version, ICF(-CY) Core Sets for Attention-Deficit Hyperactivity Disorder (ADHD). To explore the perspectives of individuals diagnosed with ADHD, self-advocates, immediate family members and professional caregivers on relevant areas of impairment and functional abilities typical for ADHD across the lifespan as operationalized by the ICF(-CY). A qualitative study using focus group discussions or semi-structured interviews of 76 participants, divided into 16 stakeholder groups. Participants from five countries (Brazil, India, Saudi Arabia, South Africa and Sweden) were included. A deductive qualitative content analysis was conducted to extract meaningful functioning and disability concepts from verbatim material. Extracted concepts were then linked to ICF(-CY) categories by independent researchers using a standardized linking procedure. In total, 82 ICF(-CY) categories were identified, of which 32 were related to activities and participation, 25 to environmental factors, 23 to body functions and 2 to body structures. Participants also provided opinions on experienced positive sides to ADHD. A high level of energy and drive, creativity, hyper-focus, agreeableness, empathy, and willingness to assist others were the most consistently reported strengths associated with ADHD. Stakeholder perspectives highlighted the need to appraise ADHD in a broader context, extending beyond diagnostic criteria into many areas of ability and disability as well as environmental facilitators and barriers. This qualitative study, along with three other studies (comprehensive scoping review, expert survey and clinical study), will provide the scientific basis to define ICF(-CY) Core Sets for ADHD, from which assessment tools can be derived for use in clinical and research setting, as well as in health care administration.

International Classification of Functioning, Disability and Health Core Sets for children and youth with cerebral palsy: a consensus meeting.

AIM: The objective of this article is to report on the Core Sets developed for children and youth aged 0 to 18 years, with cerebral palsy (CP) based on the pediatric International Classification of Functioning, Disability and Health (ICF) by the World Health Organization (WHO). METHOD: A formal decision-making and consensus process integrating evidence gathered from preparatory studies was followed. Preparatory studies included: a systematic literature review; an international expert survey; a qualitative study of children and youth with CP and their caregivers; and a clinical study. Relevant ICF categories were identified in a formal consensus process by international experts from different backgrounds. Twenty-six international experts chosen by WHO region with expertise in CP attended the consensus meeting. RESULTS: Overall, five ICF Core Sets were developed: a Comprehensive Core Set (135 ICF categories); a Common Brief (25 ICF categories); and three age-specific Core Sets: under 6 years (31 ICF categories), from 6 to <14 years (35 ICF categories) and from 14 to 18 years (37 ICF categories). INTERPRETATION: These ICF Core Sets for children and youth with CP are the first ICF-based tools developed for this population. The ICF Core Sets for children and youth with CP can be applied in clinical practice, research, teaching and administration. The application of the ICF Core Sets to this population will standardize the functional assessments of CP worldwide.

Development of ICF Core Sets to standardize assessment of functioning and impairment in ADHD: the path ahead.

In the study of health and quality of life in attention deficit/hyperactivity disorder (ADHD), it is of paramount importance to include assessment of functioning. The International Classification of Functioning, Disability and Health (ICF) provides a comprehensive, universally accepted framework for the description of functioning in relation to health conditions. In this paper, the authors outline the process to develop ICF Core Sets for ADHD. ICF Core Sets are subgroups of ICF categories selected to capture the aspects of functioning that are most likely to be affected in specific disorders. The ICF categories that will be included in the ICF Core Sets for ADHD will be determined at an ICF Core Set Consensus Conference, wherein evidence from four preliminary studies (a systematic review, an expert survey, a patient and caregiver qualitative study, and a clinical cross-sectional study) will be integrated. Comprehensive and Brief ICF Core Sets for ADHD will be developed with the goal of providing useful standards for research and clinical practice, and to generate a common language for the description of functioning in ADHD in different areas of life and across the lifespan.

The standards and tools of the European Union of Medical Specialists Physical and Rehabilitation Medicine Section and Board for rehabilitation management and care: an evidence brief for rehabilitation practitioners.

In line with the World Health Organization's Rehabilitation 2030 initiative that led to its landmark resolution on rehabilitation, the Physical and Rehabilitation Medicine (PRM) Section and Board of the European Union of Medical Specialists have been developing functioning-based standards and tools using the International Classification of Functioning, Disability and Health (ICF) as a reference framework the past few years. This evidence brief aims to enable rehabilitation practitioners to implement these functioning-based standards and tools in rehabilitation care, management, and programming by clarifying functioning as the foundational concept for rehabilitation, introducing the functioning-based standards and tools and presenting concrete applications. This evidence brief also calls for the continuous development of these standards and tools and discusses the implementation challenges and opportunities in the context of the interaction between practice, science and governance.

Characterization of an Italian population with neurological disorders in a rehabilitation setting using ClinFIT.

OBJECTIVE: To examine the functioning profile of people with neurological disorders who access rehabilitation services through ClinFIT Generic-30. METHODS: The functioning profile of people with neurological disorders accessing rehabilitation services was examined using the ClinFIT Generic-30, and the results compared with existing core set (neurological health conditions acute and post-acute,stroke, Multiple Sclerosis, Traumatic Brain Injury,Spinal Cord Injury). RESULTS: Data for 364 people were analysed. The 10 most commonly impaired ICF categories included 3 for Body Functions (exercise tolerance functions (b455), mobility of joint functions (b710), and muscle power functions (b730)) and 7 for Activities and Participation (carrying out daily routine (d230), handling stress and other psychological demands (d240), changing basic body position (d410), maintaining a body position (d415), transferring oneself (d420), walking (d450), and moving around (d455)), while the ICF categories that were severely impaired (ICF qualifiers 3 and 4) in more than 30% of the study cohort were: muscle power functions (b730), carrying out daily routine (d230), walking (d450), moving around (d455), doing housework (d640), and assisting others (d660). DISCUSSION: The current study data suggests that  ClinFIT Generic-30 appears to effectively identify impairments and/or restrictions, as perceived by individuals affected by selected health conditions. CONCLUSION: ClinFIT Generic-30 is a tool that can be used to characterize functioning profile in people with different neurological disorders and to collect important information not addressed by the disease-specific core sets (neurological health conditions acute and post-acute,stroke, Multiple Sclerosis, Traumatic Brain Injury,Spinal Cord Injury).

Overview of Available Functioning Data in Switzerland: Supporting the Use of Functioning as a Health Indicator Alongside Mortality and Morbidity.

Objectives: To identify official sources that routinely collect data on functioning in Switzerland, to provide an overview of the existing data and its comparability, and to assess the extent to which the data is suitable for developing a functioning metric and indicator. Methods: Data sources were identified through an iterative search. Standardized rules were applied to map the functioning information assessed by the sources using a current WHO functioning and disability survey as a reference framework for the content comparison. Results: Four sources were identified: the Swiss Survey of Health, Ageing and Retirement in Europe (SHARE), the Swiss Health Survey (SHS), the Lausanne cohort 65+ (Lc65+), and the Swiss Household Panel (SHP). All tools addressed sleep functions, energy level, emotional functions, and sensation of pain. Additionally, nine functioning categories were common across three sources. Conclusion: Population data sources in Switzerland routinely collect comparable functioning data, which can serve as the basis for creating a functioning indicator. Among others, this indicator is relevant to complement mortality and morbidity data and to support both the estimation of rehabilitation and long-term care needs.

Development of the International Classification of Functioning, Disability and Health core sets for traumatic brain injury: an International consensus process.

BACKGROUND: In a patient-oriented healthcare system, the integration of the functional status of the patient from the perspective of different professionals is understandable by the use of the International Classification of Functioning, Disability and Health. OBJECTIVE: A formal decision-making and consensus process is presented to develop the first version of the International Classification on Functioning, Disability and Health (ICF) Core Sets for Traumatic Brain Injury. METHOD: A panel with the results from preparatory studies that included a literature review, a qualitative study, empirical data collection and an expert survey, was presented. A consensus conference was held in Barcelona, March 2010 and 23 professionals attended representing nine countries. RESULTS: The preparatory studies identified 183 eligible categories. After the voting process, 139 constituted the Comprehensive Core Sets for TBI and 23 the Brief Core Sets for TBI. CONCLUSIONS: The consensus conference led to the integration of evidence and expert opinion based on the ICF. The adoption of the ICF Core Sets for TBI provides a basic international standard for the multidisciplinary assessment of a TBI patient's functioning.

Prioritizing risk factors and identifying target areas to address with interventions to improve sustainable employment of persons with a brain injury or a spinal cord injury - A multi-stakeholder consensus process.

Background: Achieving sustainable long-term employment is the goal of work integration for persons with acquired brain injury (ABI) or spinal cord injury (SCI). However, decreasing employment rates over time for persons with ABI and SCI indicate that remaining employed in the long-term is a challenge. Purpose: To identify the most important risk factors that pose a barrier to sustainable employment of persons with ABI or SCI from a multi-stakeholder perspective, and to propose corresponding interventions that address them. Methods: Multi-stakeholder consensus conference and follow-up survey. Results: From 31 risk factors to sustainable employment of persons with ABI or SCI identified in previous studies, nine were defined as most important to address with interventions. These risk factors either impacted the person, the work environment or service provision. Potential interventions to address these factors were proposed in mixed condition groups, of which ten were voted on as priority interventions. The follow-up survey revealed strong agreement on the intervention proposals, strong to moderate agreement on impact, but moderate to low feasibility, as most of the interventions were measures at the meso- (service) and macro- (legislation and state regulation) level. Conclusions: Holding micro-level stakeholder conferences is a valuable method for identifying the most important risk factors to sustainable employment and for developing measures to address them. To implement measures that involve decisions at the meso- or macro-level, representatives from these levels of the healthcare and social system have to be involved.

Development of simple descriptions of the ICF Generic-30 Set in different languages: laying the foundation for an ICF-based clinical tool for Europe.

BACKGROUND: Functioning is considered a third indicator of health and a key outcome in rehabilitation. A universal practical tool for collecting functioning information is essential. This tool would be ideally based on the International Classification of Functioning, Disability and Health. AIM: To report the results of the development of country/language-specific versions of an ICF-based clinical tool in six European countries. DESIGN: Consensus process. SETTING: Expert conferences. POPULATION: Multi-professional group of rehabilitation professionals in six European countries. METHODS: 1) Developed an initial proposal by translating the published English-language version of the simple descriptions into the targeted language; 2) conducted a multi-stage consensus conference to finalize the descriptions; 3) employed a three-stage multi-professional expert panel translation back to English. The consensus conference model was modified for geographically large countries. RESULTS: Croatian, Flemish/Dutch, Greek, Polish, and Turkish versions were produced. CONCLUSIONS: The creation of the country/language-specific simple descriptions is a significant part of the "system-wide implementation of the ICF" initiative that will pave the way for the implementation of the ICF in national health systems. CLINICAL REHABILITATION IMPACT: The practical ICF-based clinical tool with country/language specific versions for standardized reporting of functioning will serve as a means of integrating functioning information in national health systems and additionally for monitoring the effects of rehabilitation interventions.

An ICF-based assessment schedule to facilitate the assessment and reporting of functioning in manual medicine - low back pain as a case in point.

PURPOSE: This paper outlines the first steps toward developing the ICF-based assessment schedule for manual medicine with a focus on low back pain (LBP). It reports on the results of a consensus process to develop the default and optional versions of the set of ICF categories (ManMed Set) the assessment schedule should cover, and gives insight in expert input toward building a toolbox of instruments for assessing the ManMed Set categories. METHODS: A scoping review and qualitative study were conducted, each resulting in a list of ICF categories. These categories, along with the categories of the ICF Generic-30 Set, Comprehensive ICF Core Set for LBP, and from an existing Delphi study, served as the starting point for an established consensus process to decide on the ManMed Set. RESULTS: After alternating plenary and working group sessions, an iterative ranking process and cut-off calculation, the multi-professional and international group of 20 experts in manual medicine included 23 categories in the default ManMed version (16 + the ICF Generic-7 Set categories) and 25 in the optional version. CONCLUSIONS: Their development is a major step toward developing an assessment schedule that can be employed in standardizing the assessment and reporting of functioning in manual medicine, initially of LBP patients.Implications for rehabilitationThe ICF assessment schedule for manual medicine has potential use in supporting rehabilitation practice, such as for planning interventions, defining rehabilitation goals, and measuring and documenting functioning outcomes.It can be used to promote interdisciplinary coordination of care and facilitate communication between members of a multidisciplinary rehabilitation team within manual medicine and beyond.The ICF assessment schedule for manual medicine can facilitate rehabilitation and manual medicine research by providing evidence for optimizing rehabilitation practice.

Rehabilitation Definition for Research Purposes. A Global Stakeholders' Initiative by Cochrane Rehabilitation.

Since its foundation, Cochrane Rehabilitation has faced challenges with rehabilitation definitions because existing definitions did not indicate what rehabilitation includes and what it excludes. We aimed to develop a comprehensive and shared rehabilitation definition for research purposes to: (1) support the conduct of primary studies and systematic reviews, and (2) identify relevant systematic reviews for knowledge translation purposes. We performed a multimodal study including seven preliminary research and discussion papers, four Consensus Meetings, and three Delphi rounds with 80 rehabilitation stakeholders. The Delphi Study aimed to obtain agreement, refine and complete the items composing the definition and meanings of rehabilitation. These stakeholders covered 5 continents, representing 11 global and continental rehabilitation organizations, 11 scientific journals, 4 Cochrane Networks, and 3 Cochrane Groups, and included invited experts, and representatives of low middle-income countries and consumers. We had a 70% to 82.5% response rate to the three Delphi rounds, during which participants responded to all items (100%) and provided relevant comments (range 5.5-50% per item). This participation led to several refinements to the rehabilitation definition through three preliminary versions, and the final items reached an agreement between 88.9% and 100%. We structured the definition using the PICO (Population, Intervention, Comparison, Outcome) framework. We concluded that "In a health care context," rehabilitation is defined as a "multimodal, person-centered, collaborative process" (Intervention-general), including interventions targeting a person's "capacity (by addressing body structures, functions, and activities/participation) and/or contextual factors related to performance" (Intervention-specific) with the goal of "optimizing" the "functioning" (Outcome) of "persons with health conditions currently experiencing disability or likely to experience disability, or persons with disability" (Population). Rehabilitation requires that all the items of the definition are satisfied. We defined a "rehabilitation intervention" as "any intervention provided within the rehabilitation process." We developed a rehabilitation definition for research purposes achieving a broad agreement with global stakeholders. This definition provides explicit criteria to define rehabilitation. Using the proposed definition will improve rehabilitation research by standardizing the description of interventions. Our definition may require revision in the future, as further research enhances understanding and communication of the essence and complexity of rehabilitation.
