Brief Summary

The purpose of this research is to investigate the impacts of applying eye-gaze assistive technology (AT) in children and youth with severe disabilities and complex needs in Taiwan, where eye-gaze AT has not been researched for children yet.

Detailed Description

Background. Children and youth with severe physical disabilities often have concomitant mental impairments and complex needs in communication, and in building relationships with others. The impairments limit their participation and independence in family, school and community life. By using their eyes, the only movements they can control voluntarily, they may increase communication. Relevant research has shown that using eye-gaze AT was feasible for children with severe physical disabilities to make choices, communicate, interact or perform school tasks despite different learning curves. Use of technology may increase opportunities for engagement and self-determination for children and youth with physical disabilities and complex communication needs in family context or in school, but the research is relatively limited. It still needs more studies across countries and long-term follow-up to investigate the effects of the use of eye-gazed AT in life.

Study Aims. There are two aims in this proposed research. Aim 1: To investigate the preliminary effects of eye-gazed AT for daily participation in daily living for children and youth with severe physical disabilities and communication difficulties in Taiwan.

Aim 2: To investigate the adherence of eye-gazed AT intervention for children and youth with severe physical disabilities and communication difficulties, and the caregivers' satisfaction regarding support children and youth to use eye-gazed AT in daily living in Taiwan.

Methods. This study is conducted as a single subject design with multiple baselines across individuals. The inclusions are non-concurrent and the baselines before the intervention started were randomized with unequal of 14-30 days.

This study enrolls participants from Northern Taiwan. The researcher team contacts the practitioners in hospitals, schools or development centers to assist recruitment.

Study procedure. The eye-gaze AT intervention will be conducted for six months and follow up to seven months since provision. Before the intervention started, each of the five participants is randomly assigned to one of the pre-determined baseline lengths (14-30 days).

Repeated measures were conducted in baseline period with a minimum of five data points to judge the stability of the child's abilities and in intervention phase to establish data trends in the levels of two dependent variables, computer usage in daily living (measured by computer use diary along with log data of FocusMe program (FocusMe Inc., London, UK)), and children's activity performance using eye-gaze AT (performance scale of Canadian Occupational Performance Measure (COPM) rated by the parent or teacher). Systematic manipulation of the independent variable, the eye-gaze AT intervention was introduced in the intervention phase. The process was replicated for at least five participants to demonstrate the experiment-control effects.

In addition, other outcomes related to Activity and Participation, Body Functions and Structures and Environmental dimensions based on ICF-CY framework will be collected at baseline, after the 3-month intervention, after the 6-month intervention and 7-month after provision.

Statistical analysis. The visual analysis of single-case data will be used to determine whether there will be a relationship between the independent and dependent variables. The data of continuous variables will be presented as graphs to visually inspected regarding change of data pattern across phases separately.

Due to the small sample size, descriptive statistics will be used to summarize the results of outcome measures and reported using the narrative summary. For COPM, the score change of more than two points is considered clinically significant improvement on both performance and satisfaction scale. Besides, achieving the expected level (0) on a GAS goal is considered successful goal attainment.

Group Type: EXPERIMENTAL

Eye gaze AT intervention

Intervention Type: DEVICE

The eye-gaze AT intervention includes eye-gaze AT and service delivery to support the participants using this technology in daily life. The Tobii PCEye Mini (Tobii, Danderyd, Sweden) and specialized software are applied with adaptation to meet each child's individual needs.

To ensure the consistency of service delivery, two-day courses are conducted before the intervention. The participant's teachers or parents are invited as the main interventionist to facilitate the child's usage of eye-gaze AT in daily life under team support. The service delivery involves parents in joint goal-setting, planning, and jointly review the progress of the usage of eye-gaze AT as a family-centered practice. Individual meetings and individual supports are provided during intervention periods. The collaborative team will perform biweekly follow-up contacts during intervention periods.

The researcher will conduct the fidelity checklist every month to determine the extent of treatment integrity.
