Key result
Intraindividual affect variability is linked to increased tiredness at momentary and individual levels.
Why the study?
Does intraindividual variability in affect predict tiredness in daily life?
Observational (n=110)
Does intraindividual variability in affect predict tiredness in daily life?
Intraindividual variability in affect is a stable construct that predicts increased tiredness in daily life.
May flag tiredness risk from affect fluctuations in daily life; hypothesis-generating for stability interventions.
Intraindividual variability, along with the more frequently studied between-person variability, has been argued to be one of the basic building blocks of emotional experience. The aim of the current study is to examine whether intraindividual variability in affect predicts tiredness in daily life. Intraindividual variability in affect was studied with the experience sampling method in a group of 110 participants (aged between 19 and 84 years) during 14 consecutive days on seven randomly determined occasions per day. The results suggest that affect variability is a stable construct over time and situations. Our findings also demonstrate that intraindividual variability in affect has a unique role in predicting increased levels of tiredness at the momentary level as well at the level of individuals.
