Session 5: Conceptual Issues Related to Disability Measurement
Objectives: To examine what it means to use the ICF as a framework for disability measurement and the WG work; to discuss and clarify the meaning of words that we use to describe and measure disability; to identify areas where terminology lacks sufficient clarity and/or specificity and therefore falls short of descriptive needs; and finally, to explain and clarify how the proposed general measure captures basic activities and identifies a population at high risk of participation limitations
Session 6: Proposed Approach for Development of Extended Measurement Set/s
Objectives: To present alternative proposals for the 1st extended measurement set including purpose, rationale, international comparability, and justification for the proposed set of questions; to present a proposal for the second extended measurement set (including the purpose, rationale, etc.); to further discuss the issues of the purpose of the extended sets and prioritizing purposes, data needs (how many extended sets do we need covering which domains), relationship to the general questions (should the extended sets be used with the general questions or as separate survey questions), to discuss the timing of WG activities related to development of the extended measurement sets; and to develop priorities for work to be accomplished.

Session 7: Discussion of Methodological Issues Related to Full Population Coverage
Objectives: To discuss the issues of non-response, mode of survey administration, and proxy response in relation to health questions; to identify the impact of excluding the institutionalized population from disability surveys; and to discuss methods to estimate and control bias in disability statistics.

Session 10: Next Steps and Objectives for the 6th Meeting in Africa
Objectives: To summarize the accomplishments of the 5th meeting and outline next steps; announce the date and location of the 6th meeting and determine objectives; solicit volunteers to host the 7th WG meeting; and to close the 5th meeting.
Five workgroups will address major next steps of the WG. Chairs have been identified for each workgroup. The chairs serve as the contact for each group. Information on the workgroup topics and chairs is provided below. WG members who wish to volunteer to participate in one of these groups, please contact the workgroup chairs.
- Workgroup on General Measure/s
Chair: Barbara Altman, USA
Next steps for this group include addressing recommendations for revisions to the general measure as well as the rationale, including clarifying the issue of seriousness/severity of disability. This workgroup will evaluate the effect of question order on prevalence when the short set is placed on a larger survey. As part of future work, this workgroup will consider developing the general measure as a screener.
- Workgroup on Implementation
Chair: Joseph Muli-Kalavi, Kenya, International Development Project
Alternate: Hasheem Mannan, USA
This workgroup will serve as a resource for countries conducting the WG pre-test including any revisions needed to the implementation protocol.
- Workgroup on Extended Measure/s
Chair: Marijke de Kleijn, The Netherlands
Next steps for this workgroup is the development of a plan (blueprint) for extended sets, addressing the purpose, rationale, justification for the set and addressing international comparability. The workgroup will also formulate possible options for additional domains to be measured to address the purpose of equalization of opportunities and recommend additional domains for inclusion on one extended measurement set. Furthermore, this workgroup will also begin development of an extended set on environmental questions.
- Workgroup on Methodological Issues
Chair: Howard Meltzer, United Kingdom
This workgroup will address methodological issues of importance to the Washington Group.
- Workgroup on Analysis
Chair: Dan Mont, World Bank
During the annual meeting in Rio, this new workgroup was formed in order to plan and conduct analyses that will inform the WG work on the general measure.
