RESUMEN
It is well established that the COVID-19 pandemic increased psychological distress in many populations, particularly for people with chronic health conditions (CHCs). Web-based mental health interventions provide a scalable and cost-effective approach to providing psychological support for people disproportionately affected by the COVID-19 pandemic. The current study aimed to explore the feasibility and acceptability of a one-week web-based psychological intervention (ACT2COPE) and explore preliminary effects of the intervention on reducing depression, anxiety, and stress symptoms, and improving wellbeing and psychological flexibility in adults living with CHCs during the COVID-19 pandemic in Aotearoa (New Zealand). A pilot randomised waitlist-controlled trial explored the acceptability and preliminary efficacy of ACT2COPE among 40 participants (n = 20 in the ACT2COPE group and n = 20 in the waitlist control group). Focus groups and open-ended questions explored usability and acceptability of the intervention as well as levels of engagement and adherence to the intervention. Mixed model ANOVAs explored within and between-group differences in psychological outcomes. Qualitative findings suggested that participants found ACT2COPE acceptable and engaging. Depressive symptoms significantly decreased over time compared to the waitlist group at 4-weeks follow-up (p =.012). No other between-group differences were found. The online ACT2COPE intervention presents a promising, scalable intervention that may improve psychological outcomes in adults living with CHCs during the COVID-19 pandemic. Future research is needed to confirm these findings in a larger and more diverse population and over a longer timeframe. © 2023 The Author(s).
