RQ1.1 Measures and Analyses
EMA
We focused on the main EMA/EMI elements for compliance: the number of entered and evaluated listening situations and the number of snippets viewed. Compliance criteria were: (1) add at least 1 to 2 (i.e., ≥1.5) listening situations per day, 42 in total; (2) evaluate ≥80% of the added situations; (3a) view ≥80% of offered snippets, (3b) resulting in 33 snippets in total, and (4) view ≥10 standard library snippets. Note that participants were not provided with these or any specific targets, although various app elements (e.g., EMA notifications) did serve as incentives to stimulate daily usage. Descriptive statistics were used. The compliance criteria were based on To explore a possible impact of the COVID lockdown on the number of encountered listening situations, we included a self-designed item in the T3 questionnaire asking if participants had run into difficult listening situations (far) less, equally often, or (far) more frequently due to the COVID lockdown as compared with before.
