Note: *Facets of <strong>HIV</strong> module.<br />
defined as a history of sexual relations with an <strong>HIV</strong><br />
positive partner and/or absence of a fixed partner.<br />
The next most common risk factor was shared<br />
needles (21.6%), and then transfusion/haemophilia<br />
(15.9%) (see Table I). The mean duration of knowledge<br />
of <strong>HIV</strong> infection was 4.1 years. The CD4<br />
lymphocyte count was available in 208 participants,<br />
with a mean value of 431.8 (9263.3). Two hundred<br />
and nineteen people (71.1%) used two or more antiretroviral<br />
drugs.<br />
Psychometric properties of the <strong>WHOQOL</strong>-<strong>HIV</strong><br />
The total number of patients interviewed was 308.<br />
Twenty-nine items were unanswered once, 4 items<br />
unanswered twice, and 3 unanswered 3 times by the<br />
whole group. The number of unanswered items per<br />
facet varied from 1 through 5, and the only facet in<br />
the 308 questionnaires with 5 blank items (1.6%)<br />
concerned body image and appearance (generic,<br />
<strong>WHOQOL</strong>-100).<br />
Analysis of scores distribution in our sample<br />
revealed absence of ‘ceiling’ and ‘floor’ effects for<br />
all <strong>WHOQOL</strong>-<strong>HIV</strong> facets.<br />
Reliability and validity of the construct<br />
The 31 examined facets contain 4 items. Of the<br />
facets, 27 show a Cronbach alpha above 0.70<br />
(Table II) and range from 0.32 to 0.65 in the<br />
remaining four: cognition (Psychological domain),<br />
security and physical environment (Environment
