Interviewer instructions
<span class="h2">15.3 Section III. People characteristics</span></p>
<p>In this section, information is obtained for each of the people living in the housing unit.</p>
<p>Before requesting data for each resident, copy the details from Section II. List people and general data, their names, gender, and age, and write them down in the spaces provided. Do not forget to correct the person number when using more than one questionnaire.</p>
<p>[Figure omitted: image with text]</p>
<p>For the respondent to know who to provide the information about, start with the sentence: "Now I'm going to ask you about...", and mention the name of the person you previously wrote down.</p>
<p>Apply questions 1 through 11 for all the people who are habitual residents, including children, as well as elderly people.</p>
<p><span class="em">10. Disability</span>
<br />This question identifies the degree of difficulty people have in performing some activities in their daily lives, such as seeing, hearing, walking, remembering or concentrating, providing self-care, speaking, or communicating. Also, if they have any mental problems or conditions.</p>
<p>The question consists of two parts. The first part asks about the degree of difficulty in six activities of daily living. The second part identifies people who have a mental problem or condition.</p>
<p><span class="pg">[p. 309]</span></p>
<p>[Figure omitted: image with text]</p>
<p>To ask these questions, consider the following:</p>
<div class="i1">- Apply them to all people living in the housing unit.<br />- You must circle seven codes for each person.<br />- In infants and young children, there are cases in which congenital anomalies, illnesses, or injuries are detected that imply difficulties or limitations from birth or in the first years of life. If so, record the difficulty or limitation in the activity stated by the respondent, but if the respondent mentions that the child cannot perform some activity because they are still small, that is, it is typical of the growth stage of babies and small children, do not record it as a limitation. If in doubt, confirm each of the options with the respondent.<br />- If the person states that they have difficulties typical of an older adult, or that they have any disease or condition such as diabetes, cancer, or arthritis, among others, ask what limits them or prevents them from carrying out their daily activities according to the answer options indicated in the questions.<br />- In case the respondent anticipates the answer for one or all of the people in the housing unit, it is important that when recording the information corresponding to each one, you confirm whether or not they present some degree of difficulty for each of the activities indicated. Also, check for any mental problems or conditions by circling the appropriate code. Never record the response without confirming the information; this will ensure that the entire population with a limitation or disability is identified.</div><span class="pg">[p. 310]</span><div class="i1">- For the application of the first part, read the complete question with each of its six complementary options, as well as each of the four degrees of difficulty, wait for the answer, and circle a code for each type of activity.<br />- If the respondent expresses discomfort when you apply the DISABILITY question, even though they gave you a general answer for all the residents of the housing unit, make it clear that you have to ask the question for each of them, in order to identify the people with limitations or disabilities, without omitting any of them.</div><span class="ital">Activity limitations</span>
<br />Keep in mind that activity limitations are difficulties a person may have in performing certain tasks of daily living due to a health problem such as:</p>
<div class="i1">- Visual difficulties, to distinguish the shape, size, and color of a visual stimulus at short and long distances and even wearing glasses (frame, contact, or intra-ocular lenses), the person cannot see well due to the advanced stage of a disease or problem visual; as well as total loss and weakness of sight in one or both eyes.<br />- Hearing difficulties, in one or both ears and who, even using a hearing aid or implant, cannot hear due to the advanced stage of a disease or hearing problem, or those with total or partial hearing loss</div><span class="pg">[p. 311]</span><div class="i1">- Walking or mobility difficulties, going up or down steps or slopes using their legs, due to the total or partial lack of legs or immobility of them.<br />- Difficulties remembering or concentrating due to problems recalling, focusing, keeping attention, recording and storing information, as well as retrieving it when necessary; exclude those activities related to the process of growth or development of the child population (younger than 3 years old). Remember that they are the result of a birth or health condition.</div><span class="pg">[p. 312]</span><div class="i1">- Difficulties bathing, dressing, or eating due to problems in performing self-care tasks or limitations in washing, caring for their own body, dressing (includes taking clothes from where they are usually kept, buttoning, tying laces, etc.), eating and drinking, or taking care of their own health. It excludes those activities related to the growth or development process of the child population (younger than 3 years old).<br />- Communicating or speaking difficulties, are those problems in producing and transmitting messages through oral (spoken) language, such as expressing a fact or telling a story; it includes the loss or restriction of speech, as well as difficulties in maintaining and understanding a conversation. It excludes limitations related to the growth or development process of the child population (younger than 3 years old).</div>
