The benefits of interviewing a group includes drawing on multiple opinions and experiences at once. Unfortunately, the presence of others may intimidate PWD's and influence their responses. Women with disabilities are often difficult to interview as men may not allow them to be questioned, or will act as their spokesperson. Because many of the activities are alien to our culture, it is essential they be observed and recorded in situ. This also allows for task analysis, including a break down of physical movements, tools, and posture necessary for performance.
Photographs provide an accurate depiction for future reference.
Photographs serve four potential purposes. First, they may be used to supplement and clarify data collected using other methods i.e. photographs of a woman cooking may confirm a written description of her working posture. Second, photographs may be used independent of any other data i.e. a photograph of a stove enables one to conceptualize the challenges faced by the PWD in performing cooking activities. Finally, the photograph provides a medium by which to concisely and accurately convey information to others, especially upon returning home. Videorecording can be a culturally invasive but very accurate data collection strategy, especially for recording movement.
