Jt. Parsons et al., Maintenance of safer sexual behaviours: evaluation of a theory-based intervention for HIV seropositive men with haemophilia and their female partners, HAEMOPHILIA, 6(3), 2000, pp. 181-190
A theory-based HIV risk-reduction intervention was developed for HIV-positi
ve men with haemophilia and their HIV-negative female romantic partners. Th
e intervention was based on Prochaska and DiClemente's Transtheoretical Mod
el which describes behaviour change as an incremental, stage-based process.
The intervention targeted both communication about safer sex and safer sex
behaviours (consistent condom use or abstinence from vaginal intercourse).
A total of 255 males and 158 females from six funded haemophilia treatment
centres or patient organizations (and 27 associated subsites) participated
in the study. Baseline and follow-up (15 months after baseline) measures w
ere administered to assess safer sexual behaviours, communication about saf
er sex and condom self-efficacy. A quasi-experimental, repeated measures de
sign was utilized to compare two naturally occurring groups; those who rece
ived the full intervention package and those who received incomplete or no
intervention components. Significant intervention effects for safer sex beh
aviours, communication about safer sex and condom self-efficacy were identi
fied for the male participants, with those receiving the full intervention
package demonstrating better outcomes at follow-up. Women who received the
full intervention package were more likely to report the use of a condom by
their male partner during the last act of vaginal intercourse.
