“…However, these studies were usually based on relatively small, highly specific samples (e.g., 152 teachers of a Californian urban school district in Dunn et al, 2018; 146 general practitioners in Iran in Hadadgar et al, 2016) or school or university student samples (e.g., Anthony Jnr et al, 2020; Chai et al, 2020; Cheon et al, 2012; Liao et al, 2011). Furthermore, these studies considered participants’ intention but not the actual performance of the behavior, and focused on specific courses or forms of learning instead of general formal, non-formal, or informal LLL (e.g., intention to participate in blended learning in Anthony Jnr et al, 2020; intention to learn Artificial Intelligence in Chai et al, 2020; intention to participate in mobile learning in Cheon et al, 2012; intention to participate in math workshops for teacher professional learning in Dunn et al, 2018; intention to use e-learning to participate in continuing medical education in Hadadgar et al, 2016; intention to continue using an e-learning website in Liao et al, 2011). Beyond that, there are initial results by Van Nieuwenhove and De Wever (2021) who applied TPB to predict more general LLL intentions in the next 12 months based on a sample of 23–65-year-old adults ( N = 335).…”
