Note. Within-Person (RWP) and Between-Person (RBP) Reliability for Negative Affect (NA) and Positive Affect (PA) across Momentary Reports. SHADE and NTH are traditional Ecological Momentary Assessment (EMA) studies; ESCAPE and SAWM results are drawn from the momentary reports from hybrid designs. For clarity, this table presents the results in the upper section, followed by the necessary study characteristics needed for reliability calculations, then the reliability estimates. The Work Daily Life (WDL) EMA study is not represented in this table because the study utilized a single item measure for NA and PA, thus neither RWP nor RBP reliability could be calculated.
