Background: The aim of this study was to explore the experiences of psychologists working with people with intellectual disabilities during the initial stage of the COVID-19 lockdown in the Netherlands. Method: Five psychologists, who were affiliated with three intellectual disability services, participated in this descriptive qualitative study. Overall, they recorded 22 audio messages during the period under examination, which were analysed using thematic analysis. Results: Three themes were identified: (1) Working from home; (2) Adapting to the new reality; and (3) Advising and coaching support staff. Conclusions: This study provides critical insights into the experiences of psychologists working with people with intellectual disabilities during the initial stage of the COVID-19 lockdown. These insights can help policymakers and practitioners to prepare for either a potential second wave of COVID-19 or a future pandemic.
