Table 2. Measures of barriers to accessing health care.

Measure	Definition	Range of possible scores
Prevalence of barriers to accessing health care	Proportion of women living with HIV responding in each of the 4 response categories (1 = No problem at all, 2 = Veryslight problem, 3 = Somewhat of a problem, 4 = Major problem) for each BACS item	0–100%
Barriers to health-care index	The average number of barriers that women living with HIV indicated were problematic, regardless of the reported extent of the problem (response category 2, 3, or 4)	0–12
BACS-severity score	A measure of problem severity, calculated as the average response on the Likert scale. BACS-severity scores were calculated for each BACS item, for the BACS questionnaire overall, and for the four sub-scales. Higher scores indicate increased problem severity. Scores ≥2 were considered significant.	1–4
