“…Lawrence, 1993). Further, the role of self-efficacy has been investigated on its own and in combination with other models, especially in relation to condom use (Abraham & Sheeran, 1994;Richard & van der Pligt, 1991;Schaalma, 1993;Wilson, Zenda, McMaster, & Lavelle, 1992). For example, the health belief model (Rosenstock, 1966) has been largely applied to condom use (Hingson, Struin, Berlin, & Heeren, 1990), the protection motivation theory (Rogers, 1975) has also been tested in relation to condom use (Van der Velde & van der Pligt, 1991), and the theories of reasoned action and planned behaviour (Ajzen, 1988) have been found to be predictive of condom use intentions, oral contraceptive use intentions, and intra-uterine device use intentions (Boldero, Moore, & Rosenthal, 1992;Doll & Orth, 1993;Fisher, 1984;Jaccard & Davidson, 1972;Pagel & Davidson, 1984).…”
