“…Hofmans and colleagues (2019) outline the whole process of conducting an ESM study, including set-up and data analysis. Finally, some publications focus on narrower issues, such as the optimal ESM schedule (that is, when participants receive their daily invitations; van Berkel et al, 2019), sampling frequency and length of the survey (Eisele et al, 2020), the instructions to be used (Stone, Wen, Schneider, & Junghaenel, 2020), the estimation of reliability (Nezlek, 2017;Schönbrodt, Zygar, Nestler, Pusch, & Hagemeyer, submitted), validity (Vogelsmeier, Vermunt, van Roekel, & De Roover, 2019), or the construction of state measures (Horstmann & Ziegler, in revision). However, there are not many that focus on the very practical issues of setting up an ESM study.…”
