About this trial
This study evaluates whether an interdisciplinary case management approach based on the International Classification of Functioning, Disability and Health (ICF) and the Rehab-Cycle® framework can improve rehabilitation outcomes for adults with intellectual disabilities receiving community-based rehabilitation services.
A total of 120 adults with mild to moderate intellectual disabilities will be recruited from community rehabilitation services and randomly assigned to either an ICF-based interdisciplinary case management group or a conventional care management group. Participants in the ICF-based group will receive coordinated assessments, goal-setting, intervention planning, and outcome evaluation conducted by an interdisciplinary rehabilitation team. Participants in the control group will continue to receive standard services delivered through conventional care management practices.
The study will assess changes in functioning, activity participation, quality of life, life satisfaction, and rehabilitation team effectiveness. The findings will help determine whether ICF-based interdisciplinary case management can provide more personalized, coordinated, and effective community rehabilitation services for individuals with intellectual disabilities.

Treatments tested in this trial
ICF-Based Interdisciplinary Case Management (Rehab-Cycle®)
BehavioralParticipants will receive interdisciplinary case management based on the International Classification of Functioning, Disability and Health (ICF) framework and the Rehab-Cycle® process. The intervention includes ICF-based assessment, development of individualized functioning profiles, collaborative goal setting involving participants and healthcare professionals, interdisciplinary care planning, coordinated rehabilitation interventions, and regular interdisciplinary review meetings. Interventions are designed to address body functions, activities, participation, and environmental factors according to each participant's needs within community-based rehabilitation services.
Conventional Care Management
BehavioralParticipants will receive standard community rehabilitation services routinely provided by participating non-governmental organizations. Assessments, goal setting, intervention planning, and treatment implementation will be conducted independently by individual healthcare professionals according to usual practice. No ICF-based functioning profile, structured Rehab-Cycle® process, formal interdisciplinary case conference, or coordinated interdisciplinary intervention planning will be used.
Treatment groups
120 Participants
are divided into 2 treatment groupsGroup A: ICF-based care management group with interdisciplinary Rehab-Cycle® processExperimental treatment 1 intervention
Group B: Conventional care management group without interdisciplinary Rehab-Cycle® processActive comparator 1 intervention
Trial outcomes
Primary outcomes
1
ICF-based assessments of the core set items
The selected core set items will be used to assess (a) body functions (b117 intellectual function), (b) activity capacity and participation performance in daily living (e.g. basic interpersonal interactions) and (c) environmental and personal influence (e.g. e310 immediate family). The ICF 5-point qualifier will be used based on the converted results of the corresponding assessments with a scale from 0 (no problem) to 4 (complete problem).
Time frame

1
Satisfaction with Life Scale (SWLS)
The SWLS a brief 5-item self-report measure assessing global cognitive judgments of life satisfaction (Diener et al., 1985). Each item is rated on a 7-point Likert scale from 1 ("strongly disagree") to 7 ("strongly agree"), producing a total score between 5 and 35, with higher scores reflecting greater satisfaction. The scale captures cognitive judgments rather than emotional states, making it suitable for diverse populations. Research consistently demonstrates strong psychometric properties, including high internal consistency, good test-retest reliability, and solid construct validity across cultures and age groups. With its robust measurement performance, the SWLS is a widely used tool in health, rehabilitation, and social science research

Provider-Perceptions of Team Effectiveness (Provider-PTE)
A brief self-report questionnaire that evaluates healthcare providers' perceptions of interdisciplinary team effectiveness in delivering coordinated care. The instrument assesses key domains including communication, role clarity, shared goals, collaboration, and overall team functioning using Likert-type response scales. Higher scores indicate more positive perceptions of team effectiveness. The Provider-PTE has demonstrated good reliability and validity and is sensitive to differences in interprofessional team performance across healthcare settings. The measure will be used to assess changes in interdisciplinary team functioning associated with implementation of the ICF-based case management approach
