“…To reduce participant burden and minimise drop-out rate, researchers investigating daily mood fluctuations typically use very brief mood surveys. In many studies an approach is to have participants rate a small handful of mood adjectives that are averaged into composite scores of positive and/or negative emotion (some examples: Bastian et al, 2015;Brose et al, 2020;Buttner et al, 2015;Carr et al, 2018;Dunton et al, 2014;Forgeard et al, 2020;Fosco & Lydon-Staley, 2019;Gruber et al, 2013;Gunaydin et al, 2016;Hamilton et al, 2008;Hankin et al, 2005;Iijima et al, 2018;Koval et al, 2019;Larson et al, 2002;Maciejewski et al, 2015;McIntyre et al, 2019;Ottenstein & Lischetzke, 2019;Panaite et al, 2019;Penner et al, 1994;Ryan et al, 2010;Spindler et al, 2016;van Laethem et al, 2016;Wichers et al, 2009). The measures used are generally reported to have good internal consistency (i.e., Cronbach's alpha values generally above 0.7).…”
