For many practitioners in schools and clinics, collecting data to show the effectiveness of an intervention is probably one of the most important yet challenging components of intervention implementation. This article provides practitioners with an example case study of how data can be organized and collected to determine the effectiveness of a social skills group intervention. Techniques to establish individual and group goals, determine a method to collect data, collect baseline data, and monitor progress are described. Challenges and practical strategies are discussed, and useful and specific suggestions are provided.

Objective: The Internet and other electronic media may provide one part of a solution for reducing disparities in the availability of medical services. From a patient-centred perspective, an individual with a chronic, degenerative condition may ask what information is available that I can use to manage changes in my functional capacity over time, and how effective is this? The purpose of this study was to assess the availability and quality of a sample of online self-help videos which address common functional problems ubiquitous among individuals living with one such condition: Parkinson’s disease. Design: Cross-sectional survey. Setting: Internet. Method: An Internet search was conducted to identify self-help videos offering instruction on how to manage changes in function, and each video was assessed using 17 factors relevant to instructional quality. Results: Of 295 videos, 14 (4.7%) provided self-help instruction for three chosen skills. The quality of instructional presentation averaged 2.75 on a 5-point scale, where 1 was poor and 5 was excellent. Conclusion: The identified self-help videos that addressed maintaining functional outcomes for individuals living with Parkinson’s disease varied significantly in quality, and few met accepted standards of instructional design. Future research into effective presentation modes and patient functional capacity needs might usefully develop a patient-centred curriculum that can be delivered utilising multiple platforms. This area of research is critical in rehabilitation and other health settings to enhance assistance for individuals living with chronic health conditions and their families and caregivers.
