It is one of those stores where you feel scrutinized by security cameras even if you do not roll in on a battered old scooter held together by bright red airline baggage tape purchase ampicillin 250mg with amex. The saleslady eyed us with barely veiled suspicion as we sorted through the tie rack. When we finally selected a tie and pulled out our credit card, she brightened up and began talking about her mother. She had largely recovered but was terri- fied of falling, afraid to leave her house. On a trip abroad, the saleslady found a four-wheeled folding walker with brakes on the handlebars and a little seat for the user to rest. She brought the walker home, but her mother was still afraid and wouldn’t walk outside. Two major themes link this and many similar interactions of my “rolling focus group”—the strangers who talk to me as I roll in my scooter- wheelchair. The first theme is acknowledged loss and sorrow at becoming less able to walk. The second theme quickly follows—hope for returning mobility, even if mechanized. Many confidants are “baby boomers,” wor- ried about increasingly limited parents. Others are themselves slowed by chronic conditions, such as arthritis or diabetes. Some, like the saleslady’s mother, are isolated, afraid or unwilling to leave their homes for varying reasons, from intractable pain to fear of falling to embarrassment and reluc- tance to use or be seen with a cane or walker, let alone a wheelchair. They once traveled the globe and zipped through ever-lengthening spaces—giant office complexes, mega-shopping 1 2 obility Limits malls, enormous superstores—but now difficulty walking is slowing them down and circumscribing their reach. They want help getting around, smoothing and speeding their way, if not by walking then by mechanical means. This book explores the issues that arise when walking fails as progressive chronic health conditions compromise people’s everyday lives, partly be- cause of personal physical and emotional consequences and partly because of persisting societal and environmental barriers.

X Has a follow-up letter and duplicate questionnaire been sent in cases of none response? QUESTIONNAIRE DESIGN CHECKLIST X Make your questionnaire as short as possible ampicillin 500mg mastercard. X Don’t assume knowledge or make it seem that you expect a certain level of knowledge by the way your questions are worded. X Decide whether you’re interested in behaviour, beliefs, attitudes or characteristics or a combination of the above. X Make sure you have made the right decisions concern- ing open-ended questions, closed-ended questions or a combination of both. X Decide whether your questionnaire is to be self-admi- nistered or interviewer administered. X Include a covering letter with information about who the research is for and what will happen to the results. X Include details about how the questionnaire is to be re- turned (making sure you enclose a pre-paid envelope if you need the respondent to return the form to you). X Make sure you include a date by which time you would like the questionnaire returned. X Pilot the questionnaire and instructions to check that all can be understood. It is a procedure for generating under- standing about the way of life of others. However, as there are many practical ‘how to’ issues involved in the use of participant observation, I am going to discuss it as a re- search method. But as you will see, there are several meth- odological issues which are raised in the following discussion, especially concerning ethics and the personal role of the researcher. Participant observation can be carried out within any community, culture or context which is different to the usual community and/or culture of the researcher.
