Introduction: Adults with intellectual developmental disorders may have difficulties undertaking activities of daily living. This study aimed to identify changes in independence in activities of daily living following learning support using individualized everyday technologies. Method: A double-baseline case study design explored the use of everyday technology applications and devices to support functional performance of three men aged 32, 33, and 55 years, with mild to moderate intellectual disabilities. Performance of selected tasks was video-recorded and analysed on four occasions for each participant. Baselines were recorded twice before intervention to ensure the participant's performance of the selected task was consistent. The intervention video was recorded at the midpoint of the participant's engagement in the study. Post-intervention video was recorded approximately 1 month after the intervention ended. Results: All three participants' functional performance of an activity of daily living task improved in accuracy and efficiency as cues from support workers were gradually faded. After the learning support ceased, technology continued to provide environmental support of participants' ongoing independence and efficient performance of the activity. Conclusion: Everyday technology applications and devices can be utilized together with a guided and structured client-centred approach and task-specific training with individuals with disability and learning difficulties.

Introduction: Individuals with Intellectual and Developmental Disabilities (IDD) experience broad impairments that affect their functional performance and consequently result in the need for supervision and assistance on a daily basis. The literature contains effectiveness studies of functional interventions provided to adolescents and adults with IDD. However, existing differences in participant characteristics, study design, and type of functional intervention limit the ability to derive clinical evidence-based decisions. This scoping review sought to explore the breadth and depth of evidence related to interventions designed to promote everyday performance of adolescents and adults with IDD. Methods: We conducted an electronic and hand search that yielded 1568 papers, after an extensive selection process reduced to a sample of 24 studies. Results: A three-step extraction process of the 24 studies revealed 16 studies used functional training and technology-based approaches to teach individuals with IDD functional skills. Seven studies used functional training without a technology component, and two studies used functional training while comparing technology-based to non-technology based approaches. Overall, it appeared that functional training with the use of technology, especially Video Modelling (VM) and Prompting, were the most frequently and effectively used interventions to promote everyday performance. Gaps in research include limited studies on middle and older aged adults with moderate to severe IDD, minimal use of self-chosen goals or activities and use of technology as a continuous support. Conclusion: Our findings show a lack of studies for individuals age 30 and above with severe IDD. Additionally, this scoping review highlight that everyday functional performance of adolescents and adults with IDD can be enhanced with the usage of technology based functional interventions utilising VM and prompting methods.
