This article reviews recent developments in research on and with ILM, addressing study design, data quality, and data analysis. Regarding study design, it describes experimental approaches including just-in-time adaptive interventions (JITAI), within-person encouragement designs, and measurement burst designs. Regarding data quality, it discusses compliance, missing data, careless responses, measurement reactivity, reliability, and validity. It describes challenges in data analysis and illustrates data-analytic approaches with sample studies. The article concludes with a discussion of implications for future research in Work and Organizational Psychology, highlighting the importance of recruiting study participants who are best suited to the research questions to be addressed.
