Research summary
An estimated 37,000 people in Scotland are infected with hepatitis C, with around 90% of new infections occurring via injecting drug use. A number of studies have investigated the association between self-efficacy and substance abuse. These investigations were not translated into the incorporation of self-efficacy into the design of treatment interventions. Implementation intentions can have an effect on behaviour and self-efficacy because of heightened accessibility to actions planned for particular situations, providing the individual with specific coping and action skills. Using a volitional help sheet can provide participants with a structured approach to creating effective implementation intentions. No published study to date has investigated the use of implementation intentions to increase self-efficacy to reduce injecting drug behaviour.
The National Health Service incurs into considerable costs to fund patients’ HCV treatment, as this is cost-effective within the model of treatment as prevention. Once treated, there is the chance patients may become reinfected with HCV if they encounter further risk of transmission. In Tayside the rate of reinfection within the PWID treated population reaches 10%. This study aims to deliver a behaviour change intervention to reduce rates of HCV reinfection by intervening on patients’ self-efficacy and their injecting risk behaviour.
The sample will involve PWID who are on treatment for HCV infection in NHS Tayside. One-hundred and twenty-six participants will be recruited and randomised to intervention and control groups.
The intervention will be a longitudinal randomised controlled trial. The data collection will be carried out over 5 visits. The intervention will entail completing the volitional help sheet with the participants to create implementation intentions. Baseline measures on injecting risk behaviour, self-efficacy, social norms, social connectedness, group identification, therapeutic alliance and mental health will be taken over two visits (consent visit and randomisation/intervention visit), and some measures will be repeated throughout the 5 visits.REC name
