Handbook of Life-Span Development (2010, background): “Such aggregation may be necessary for conventional longitudinal studies in which each person has been measured only a few times, but it requires several untenable assumptions (Molenaar, 2004).”
Small Sample Size Solutions (2020, methodology): “Finally, when using the single or classical SEm, we need to assume that every examinee is tested with an equal measurement error variance (see Molenaar, 2004; Sijtsma, 2009).”
Group search algorithm recovers effective connectivity maps for individuals in homogeneous and heterogeneous samples (2012, background): “On the one hand, true heterogeneity in individual processes may make group-level findings erroneous because the resulting map may not apply to any one individual (Miller and van Horn, 2007; Molenaar, 2004; Ramsey et al., 2010).”
A model for personality at three levels (2015, background): “Indeed, to confuse the dynamics within individuals with the averages between individuals is to mistakenly assume ergodicity (Molenaar, 2004).”
On the Use, the Misuse, and the Very Limited Usefulness of Cronbach’s Alpha (2008, methodology): “Molenaar (2004) reported that a (Big) 5-factor personality structure that was found at the group level on the basis of a sample of observations collected at one point in time did not correspond to the different factorial structures characteristic of different individuals 118 PSYCHOMETRIKA”
Introduction: The Person-oriented approach: Roots and roads to the future (2015, background): “There are strong arguments against using findings from standard studies of inter-individual variation to make inferences to what is valid at the individual level (Molenaar, 2004).”
The person-oriented approach: A short theoretical and practical guide (2014, methodology): “One approach in person-oriented research is the study of the single individual (e.g. Molenaar, 2004; Nesselroade & Ford, 1985).”
Lack of Theory Building and Testing Impedes Progress in The Factor and Network Literature (2020, background): “Critics have pointed out this mismatch: identifying a relation between sleep problems and sad mood at the between-person level provides little information of this relation at the within-person level (Bos et al., 2017; Fisher, Medaglia, & Jeronimus, 2018; Molenaar, 2004).”
Depression sum-scores don’t add up: why analyzing specific depression symptoms is essential (2015, background): “Overall, a growing chorus of voices advocates the study of interindividual differences [89-91] which may pave the way towards the development of more personalized treatment approaches.”
The Experimental Methodology of Constructive Microgenesis (2009, neutral): “In summary, aggregate analysis can be a powerful tool in uncovering general trends within a sample, although it also comes with a number of limitations: (1) We cannot treat variations occurring within a population as if they applied to individuals ( Molenaar, 2004a, b; Molenaar & Valsiner, 2005).”
Correlation and Causation in the Study of Personality (2012, background): “Mulaik (2005) reviewed certain aspects of the controversies; noteworthy recent contributions include Borsboom, Mellenbergh, and van Heerden (2003), Molenaar (2004), Bartholomew (2004), Ashton and Lee (2005), and Bartholomew, Deary, and Lawn (2009).”
Focus Article: Idiographic Filters for Psychological Constructs (2007, methodology): “It is on this general line of approach that we rely to accommodate both idiographic and nomothetic concerns (see e.g., Molenaar, 2004; Nesselroade & Molenaar, 1999).”
The Brief State Rumination Inventory (BSRI): Validation and Psychometric Evaluation (2018, background): “, Big Five factor solutions) may be blurred at state level (i.e., Borkenau and Ostendorf 1998; Molenaar 2004).”
Dynamic Latent Class Analysis (2017, background): “Such an idiographic approach has been advocated for decades in psychology (cf. Molenaar, 2004).”
The two disciplines of scientific psychology, or: the disunity of psychology as a working hypothesis (2009, result): “In this case, one needs a condition known as ergodicity ( Molenaar, 2004 ): that is, the results of the analysis as n (the number of persons) approaches infinity must be the same as the results of the analysis as t (the number of time points) approaches infinity.”
