In considering the evidence and reaching its conclusions, the Committee was aware of NICE's duties under the equalities legislation, and considered whether those duties required it to alter or to add to its recommendations in any way. The Committee was aware that a number of the questions in the DLQI focus on aspects that depend on physical activity, such as shopping, working in the home or garden, or sport. The DLQI would therefore need to be used judiciously in people with a physical disability to take account of their lower baseline level of physical activity. Furthermore, sensory or learning disabilities, or other communication difficulties, could also affect the responses to the DLQI. The Committee agreed that in such cases, healthcare professionals should ensure that the DLQI continues to be a sufficiently accurate measure.
