Participants were asked to indicate their level of confidence in their ability to perform the specified behaviors. Responses were given using an 11-point scale ranging from 0 to 100 (i.e. 0, 10, 20, …, 100), with 0 anchored as ‘Could not do it at all’ and 100 anchored as ‘Certain could do it’. HAART refers to highly active antiretroviral therapy.
