ABSTRACT

Over the last few years, I and my colleagues have carried out a series of studies on behavioural aspects of AIDS (Gold, Karmiloff-Smith, Skinner, & Morton, 1992; Gold & Skinner, 1992; Gold, Skinner, Grant, & Plummer, 1991; Gold, Skinner, & Ross, 1992). The studies targeted different populations—three employed samples of gay men, and one a sample of heterosexual students 1 —but each had the same aim: to investigate factors that may contribute to decisions to have anal/vaginal intercourse without using a condom (I will refer to this as 'unprotected' intercourse).
