“…Active-sensing techniques which require participants to actively log data or responses are the gold standard for ambulatory assessment of affect and internal experiences (Ebner-Priemer & Trull, 2009; Mehl & Conner, 2011). Repeated surveying of subjective experience, also referred to as ecological momentary assessment (EMA), was pioneered in the 1980s by Csikszentmihalyi and colleagues (Csikczentmihalyi & Larson, 1983;Shiffman, Stone, & Hufford, 2008) and is now a well-established method within psychology (Bolger & Laurenceau, 2013 (Chan et al, 2018). While EMA has historically not been subject to the same standards as traditional questionnaires within psychology, experts in EMA design now emphasize these concerns (Stone, 2017;Stone & Shiffman, 2002), recommending, for example, that a minimum of three items be used to address individual constructs when examining within-person across-time variation (Bolger & Laurenceau, 2013;Cranford et al, 2006).…”
