Washington City Group on Disability Statistics February 18-20, 2002 5 LFS: content and structure of module
6
Washington City Group on Disability Statistics February 18-20, 2002 6 LFS: Specification of the 2002 ad hoc module on employment of disabled people
7
Washington City Group on Disability Statistics February 18-20, 2002 7 LFS: Explanatory notes - description of variable The first variable introduces the topic of a health problem and it is this variable along with its impact which are used as the statistic for setting clear goals and targets for the employment of disabled people. Thus one can look at the distribution of disabled people according to their economic activity by age, sex and, where appropriate, type of employment.

Washington City Group on Disability Statistics February 18-20, 2002 8 LFS: Explanatory notes - instructions Interviewing :Longstanding Coverage of health problems Coding : Single event, continuous health problem Recurrent or episodic conditions Terminal illness or outcome dependent on treatment
9
Washington City Group on Disability Statistics February 18-20, 2002 9 LFS: Reference questionnaire Introductory text to be read out by interviewer: ‘The following few questions are about your health in relation to work. What people can do at work is often dependent on their health. Some people may have physical health problems or disabilities such as heart problems, respiratory problems, or difficulties in walking; others may have sight or hearing problems even wearing glasses or hearing aids, whereas others may have psychological or emotional problems. Health problems also include such illnesses as diabetes, dyslexia, epilepsy, problems with digestion as well as skin complaints’. Variable 1, Column 220. Do you have any longstanding health problem or disability?

Washington City Group on Disability Statistics February 18-20, 2002 12 STEPS IN RESPONSE CONVERSION Define measure of interest Estimate conversion key Convert to common scale repeatedly 123 once
13
Washington City Group on Disability Statistics February 18-20, 2002 13 WHY RESPONSE CONVERSION? Works on existing data Cost-effective Assumptions can be tested Well-established mathematical framework Indicators on interval scale Activities can be separated into routines
14
Washington City Group on Disability Statistics February 18-20, 2002 14 CONCLUSION Developmental work both at the input and output –Input : content / items (conceptual description) reference instrument operational instrument –Output : statistical tools e.g. response conversion
