The aim of this case series is to begin to explore whether the Teen Triple P program may improve treatment adherence, parent-child relationships, parenting experiences and parent and adolescent wellbeing in families with an adolescent with CF. Research commonly reports that adherence rates to treatment are consistently lower in this age group, with variables such as parent-child conflict, parent stress and the child's increasing independence all being influential factors. Previous research has suggested that family based interventions may facilitate with treatment adherence in this population, but little research has investigated the effectiveness of specific parenting and family based interventions. Triple P is an internationally recognized and extensively researched parenting intervention that has been found to support families from an array of clinical and non-clinical samples, and has been shown to reduce family conflict in other chronic health conditions. No research to date has examined the use Triple P interventions in cystic fibrosis and so hence the current research.
A within subjects clinical case series using an A-B multiple baseline design will be used. This type of design exposes participating parents to a multiple baseline period (phase A) followed by an intervention phase (phase B). This controls for potential confounds, which increases confidence that change is attributable to the use of the parenting intervention. The baseline phase will vary in length from 2 to 6 weeks. During this phase, parents will complete the treatment adherence questionnaire and parenting scale (outlined in the outcome measures section) at weekly intervals which will take 10 minutes each week (the first and last baseline session will involve completing all questionnaires stated in the primary and secondary outcome measures section). The baseline phase will be followed by the 10 week intervention phase. Here parents will commence the self-directed Teen Triple P programme. Parents will be posted a copy of the Teen Triple P workbook. They will complete a 1 hour module of Triple P each week and will also continue to complete the treatment adherence questionnaire and parenting scale each week. At week 5 and 10 of the intervention, the full set of outcome questionnaires will be administered, as well as a satisfaction survey to determine how parents are finding the Triple P intervention. Once the 10 week Triple P intervention has been completed a period of 4 weeks will elapse before the researcher will contact the parents again in order for them to complete a set of 1 month follow up questionnaires, as well as answering some questions about their experiences of taking part in the Triple P intervention.
Children themselves will not be required to participate in any study related activity as this is primarily a parenting intervention.
