Description

For persons under age 18 who have at least one activity limitation (LANY), CLIMADD reports whether the person or person's guardian identified, from an interviewer-provided flashcard listing possible causes of activity limitations, either attention deficit disorder (ADD) or attention deficit hyperactivity disorder (ADHD) as a cause of any activity limitation.

Data Collection

CLIMADD is one of a set of variables in the Health Status and Limitation of Activities section of the NHIS Family Core. The question, "What conditions or health problems cause [person's] limitations?," (with ADD or ADHD as a possible answer) comes only if specific answers are provided to a sequence of preceding questions that vary according to the age of the subject.

[show more]

These questions, and the necessary answers, are:

Persons under age 5

If there is an affirmative answer to the question, "Is [person] limited in the kind or amount of play activities he or she can do because of a physical, mental, or emotional problem?" (LAPLAYAL and LAPLAYAM), then the question for which ADD or ADHD is a possible answer is asked.

Persons age 3-17

If there is an affirmative answer to the question, "Because of a physical, mental or emotional problem, [does] [person] need the help of other persons with personal care needs, such as eating, bathing, dressing, or getting around inside this home?" (LADL), then the question for which ADD or ADHD is a possible answer is asked.

Persons under age 18

If there is an affirmative answer to the question, "Does [person] receive Special Educational or Early Intervention Services?" (LASPED), then the question for which ADD or ADHD is a possible answer is asked.

If there is an affirmative answer to the question, "Because of a health problem, [does] [person] have difficulty walking without using any special equipment?" (LAWALK), then the question for which ADD or ADHD is a possible answer is asked.

If there is an affirmative answer to the question, "[Is] [person] limited in any way because of difficulty remembering or because [they] experience periods of confusion?" (LAMEMRY), then the question for which ADD or ADHD is a possible answer is asked.

If there is an affirmative answer to the question, "Is [person] limited in any way in any activities because of physical, mental or emotional problems?" (LAOTHER), then the question for which ADD or ADHD is a possible answer is asked.

Other Possible Causes of Activity Limitations[show more]

Other possible causes of activity limitations for persons under age 18, not listed on the flashcard provided to respondents, but based on "other" responses provided by respondents to the question, "What conditions or health problems cause [person's] limitations?," include:

First unclassified problem for children (CLIMCNEC1)

Second unclassified problem for children (CLIMCNEC2)

Definitions[show more]

The following definitions provide information about various concepts used in the sequence of questions identified above:

"Attention Deficit Hyperactivity Disorder": According to the Field Representative's Manuals for 2001 forward, attention deficit hyperactivity disorder - also referred to as attention deficit disorder, ADD or ADHD - "is diagnosed by a health professional and is characterized by problems with attention, impulsiveness, hyperactivity, school problems, and sometimes aggression."

"Limited": According to the Field Representative's Manuals for 2001 forward, "limited" refers to "a person's ability to only partially perform a specific activity, perform that activity only part of the time, or not perform that activity at all. "Moreover, interviewers were instructed not to define this term to respondents. If asked for a definition, interviewers were to emphasize that the survey is interested in whether the respondent believes that the person is limited in the specific activity.

"Health Problem": According to the Field Representative's Manuals for 2001 forward, a "health problem" is respondent defined. "Generally speaking though, it is any condition, physical, mental, or emotional, which causes limitation in activity." Moreover, the Manuals say that it is not important for the respondent to differentiate between a "condition" and a "health problem."

"Condition": According to the Field Representative's Manuals for 2001 forward, the presence of a condition is determined by the respondent's perception "of a departure from physical, mental or emotional well-being. Included are specific health problems such as missing an extremity or organ, the name of a disease, a symptom, the result of an accident or some other type of impairment. Also included are vague disorders and health problems not always thought of as 'illnesses,' such as alcoholism, drug-related problems, senility, depression, [or] anxiety." Interviewers were instructed to "consider as a condition any response describing a health problem of any kind."

"Problem": The Field Representative's Manuals for 2001 forward defined a problem as the respondent's perception "of a chronic, perhaps permanent, departure from physical, mental or emotional well being. Physical, mental or emotional problem is respondent defined."

"In any way": The 1997-2000 Field Representative's Manuals define the expression "in any way" (such as in the question "[Is] [person] limited in any way because of difficulty remembering or because [he or she] experience[s] periods of confusion?" (LAMEMRY)) as referring to "activities that are normal for most people of that age."

"Special Education and Early Intervention Services": According to the Field Representative's Manuals for 2001 forward, special education and early intervention services "are designed to meet the needs of children with special needs and/or disabilities. Special Education involves special teaching programs, paid for by the public school system that may take place at a regular school, a special school, a private school, at home, or at a hospital. Early intervention services are designed for very young children, and may include, but are not limited to medical and social services, parental counseling, and therapy that may be provided at the child's home, a medical center, a day care center, or other place."

"Help from Another Person": According to the Field Representative's Manuals for 2001 forward, help from another person "is considered to be hands on assistance with performing an activity. An 'other person' may be a friend, relative, paid helper, volunteer from an agency or organization or anyone else who helps the family member in doing the activities mentioned. He or she may be a household member or a nonhousehold member."

"Special Equipment": According to the Field Representative's Manuals for 2001 forward, special equipment includes "any device, tool, utensil, instrument, implement, etc. used as an aid in performing an activity because of a physical, mental or emotional problem."

Comparability

For 2002 forward, the variable is completely comparable.

In 2001, a small number of cases were coded as "no condition at all" (IPUMS NHIS code 6) for the cause of activity limitation. If researchers are interested in only persons (under age 18) with at least one condition causing an activity limitation, then the response of "no condition at all" can be recoded as "not in universe" (IPUMS NHIS code 0). Using this recode, the variable is completely comparable for 2001 forward.
