Adaptation of REDCHIP Intervention for the Portuguese Context

One of the principal fears experienced by parents of young children with T1D is related to the occurrence of hypoglycemia episodes. These events can occur on a daily basis (i.e., often triggered by excessive exercise and/or prolonged periods without food intake) and can lead to severe acute consequences (i.e., seizures and coma) as well as long-term complications (i.e., cognitive decline). Moreover, young children often demonstrate reduced awareness for hypoglycemia and a limited ability to report its symptoms (i.e., sweating, shaking and dizziness) making it challenging for parents and other adult caregivers to detect and treat a hypoglycemic event. Combined these circumstances significantly contribute to heightened parental FH, which in some cases escalate into clinical phobia. In line with the theoretical model of caregiver fear of hypoglycemia, higher parental FH is frequently associated with avoidant behaviors and maladaptive coping strategies related to hypoglycemia. These patterns may contribute to persistently higher glycemic levels and increased variability, which, in turn, can serve as a catalyst for the development of T1D complications in their child. The literature has highlighted the potential impact of parental FH on children's glycemic outcomes and T1D management. It is also unclear whether routine use of an insulin pump or continuous glucose monitor can help to reduce FH in parents of very young children with T1D without the addition of psychological support, suggesting it is a high priority to design and test interventions to effectively treat parental FH, enhance parental well-being, and promote their T1D treatment engagement.

Thus, the original structure of the manualized REDCHiP intervention, is 10 video-based telehealth sessions (i.e.,7 group and 3 individual sessions with duration of 30 to 60 minutes). The present format of the Portuguese REDCHiP will have a 10 video-based telehealth sessions, all in group format, targeting parents of young children (≤ 8 years old) with T1D followed on two major hospitals in Lisbon, Portugal (i.e., Santa Maria Hospital and Dona Estefânia Hospital). This intervention is grounded in Cognitive Behavioral Therapy (CBT) principles, and is designed to address parents FH, and their avoidant coping behaviors related to FH. In addition, the sessions also focus on strengthening parents' coping strategies associated with T1D management and helping them to reduce feelings of diabetes distress Based on previous REDCHiP findings, and with the reported acceptability and feasibility of the intervention study, the investigators hypothesize that participants of intervention group will report lower levels of FH and better glycemic outcomes at immediate post-intervention compared to TAU group. The investigators anticipate group differences in these outcomes at three-month follow up. Furthermore, the investigators expect that REDCHiP will lead to improvements in all psychosocial adjustment factors (i.e., FH, DD, ER, RC, anxiety and depression) among all parents after receiving the REDCHiP intervention.

Accordingly, this protocol outlines the first attempt to culturally adapt and implement the telehealth REDCHiP intervention beyond the United States context.
