extent of <strong>in</strong>dividual function<strong>in</strong>g due <strong>to</strong> impairments], and “participation” [the nature and extent of<br />

a person’s <strong>in</strong>volvement <strong>with</strong> life situations] respectively”.<br />

5. While the language of ICIDH-2 is dense, the <strong>in</strong>tuition is simple. Limitations on PWD<br />

participation <strong>in</strong> the life of their society are created by the <strong>in</strong>teraction of general environmental<br />

fac<strong>to</strong>rs (e.g. the built environment; societal attitudes), <strong>in</strong>dividual-specific fac<strong>to</strong>rs (e.g. gender, age<br />

or education), and the impairment(s) that the <strong>in</strong>dividual has. The ICIDH-2 is sometimes termed a<br />

biopsychosocial model of disability. The model is presented <strong>in</strong> diagrammatic form <strong>in</strong> Figure 4.<br />

6. Metts provides a useful explication of the ICIDH-2 approach, not<strong>in</strong>g that “people may…:<br />

• have impairments <strong>with</strong>out hav<strong>in</strong>g activity limitations (e.g. disfigurement but no activity<br />

limitation)<br />

• have activity limitations <strong>with</strong>out evident impairments (e.g. experience poor performance<br />

<strong>in</strong> activities due <strong>to</strong> disease)<br />

• have limited participation <strong>with</strong>out impairments or activity limitations (e.g. discrim<strong>in</strong>ation<br />

due <strong>to</strong> past mental illness or HIV)<br />

• experience a degree of <strong>in</strong>fluence <strong>in</strong> the reverse direction (e.g. experience muscular<br />

atrophy due <strong>to</strong> <strong>in</strong>activity or loss of social skills due <strong>to</strong> <strong>in</strong>stitutionalization).”<br />

7. The ICIDH-2 was followed by the International Classification of Function<strong>in</strong>g (ICF),<br />

which skips the l<strong>in</strong>kage between health conditions and function<strong>in</strong>g, and classifies function<strong>in</strong>g<br />

directly, us<strong>in</strong>g the same doma<strong>in</strong>s as ICIDH-2: body functions, activities and participation). The<br />

ICF has developed more detailed classifications of function<strong>in</strong>g <strong>with</strong> respect <strong>to</strong> products and<br />

technology, natural and man-made environments, support and relationships, attitudes, and<br />

services, systems and policies. 9<br />

8. In broad terms, this report adopts the ICIDH-2 approach <strong>to</strong> disability, though the<br />

practical differences <strong>to</strong> the ICF approach are not significant. The comb<strong>in</strong>ation of medically-based<br />

and socially determ<strong>in</strong>ed def<strong>in</strong>itions of disability that it offers seems particularly appropriate <strong>to</strong> a<br />

poor develop<strong>in</strong>g country. It is also useful <strong>in</strong> terms of public policy, where determ<strong>in</strong>ations of<br />
