“…Several studies reported success with the PD approach for children with autism using a variety of approaches. Focus groups (Boyle & Arnedillo-Sánchez, 2016;Grond et al, 2019), brainstorming (Soysa et al, 2018), feedback on design choices (Frauenberger et al, 2012) (Kim et al, 2014), scenario creation (Millen, Cobb & Patel, 2011), questionnaire (Boyle & Arnedillo-Sánchez, 2016), narrative structure and personalized storage box (Malinverni et al, 2014), observation (Madsen et al, 2009), and question and answer game (Porcino et al, 2014) are some of the methods used. Unexpected situations can arise related to ethical considerations, such as attracting and retaining participants, supporting their engagement, extracting design information from PD activities, ending PD projects, and managing resources (Constantin et al, 2019).…”
