DOI: 10.1016/j.psyneuen.2017.01.026
Abstract: Most of the variance in diurnal cortisol is attributable to intraindividual variability (IIV), defined as relatively short-term, reversible changes. Multiple methods for measuring IIV have been proposed, and some have already been applied to cortisol… read more here.

DOI: 10.1016/j.sleh.2019.07.009
Abstract: OBJECTIVES Research suggests strong associations between habitual sleep parameters (eg, mean duration, timing, efficiency), perceived stress, and insomnia symptoms. The associations between intraindividual variability (IIV; night-to-night within-person variation) in sleep, perceived stress, and insomnia have… read more here.

DOI: 10.1017/s1355617720000879
Abstract: Abstract Objective: We examined whether intraindividual variability (IIV) across tests of executive functions (EF-IIV) is elevated in Veterans with a history of mild traumatic brain injury (mTBI) relative to military controls (MCs) without a history… read more here.

DOI: 10.1037/ccp0000344
Abstract: Objective: Sudden gains are robust predictors of outcome in psychotherapy. However, previous attempts at predicting sudden gains have yielded inconclusive findings. The aim of the present study was to examine a novel, transdiagnostic, transtherapeutic predictor… read more here.

DOI: 10.1037/neu0000809
Abstract: OBJECTIVE Cognitive impairment is common among individuals with Parkinson's disease (PD). Intraindividual variability (IIV) is a measure of variability across multiple tasks of cognitive functioning. Due to the limited amount of research, particularly among individuals… read more here.

DOI: 10.1080/00273171.2018.1457939
Abstract: ABSTRACT Intraindividual variability can be measured by the intraindividual standard deviation (), intraindividual variance (), estimated hth-order autocorrelation coefficient (), and mean square successive difference (). Unresolved issues exist in the research on reliabilities of… read more here.
