Interactions do not only tell us when, but can also tell us how: Testing process hypotheses by interaction (2011, background): “…that, while the association between TV and Y is mathematically partialled out in (II), the effect of TV on Y still did in fact occur during the data collection for the study (an important point in the logic of controlling covariates which is not entirely unproblematic, see Miller & Chapman, 2001).”
Are bilingual advantages dependent upon specific tasks or specific bilingual experiences? (2014, background): “As Miller and Chapman (2001) point out in their landmark article:”
Repetitive regret, depression, and anxiety: findings from a nationally representative survey (2009, background): “…regret and rumination, we recognize that interpretation of anCova results may be problematic when the independent variables differ on the covariate (miller & Chapman, 2001 ). in the present case, however, inclusion of the covariates did not alter the main finding. if inclusion of covariates…”
Specificity of cognitive emotion regulation strategies: a transdiagnostic examination. (2010, background): “…the interpretation of the residual variance that results when a covariate has been included in a multivariate model is not without problems (see Miller & Chapman, 2001), it is still a parsimonious and straightforward way to identify which variables aremore strongly associated with anxiety and…”
Facial Emotion Recognition in Autism Spectrum Disorders: A Review of Behavioral and Neuroimaging Studies (2010, background): “1989) have statistically controlled for IQ to address the issue of uneven IQ profiles, which in addition to limiting statistical power might not be appropriate when studying pre-existing (instead of randomly assigned) groups (Miller and Chapman 2001).”
Evidence of Broad Deficits in Emotion Regulation Associated with Chronic Worry and Generalized Anxiety Disorder (2006, background): “Miller and Chapman (2001) question the use of the ANCOVA when group differences exist on the covariate in question, suggesting that it may be invalid to assume that a theoretical entity (such as ‘‘GAD’’) exists in a meaningful way beyond its association with a co-varying entity (such as ‘‘negative ”
Why IQ is not a covariate in cognitive studies of neurodevelopmental disorders (2009, methodology): “…it becomes meaningless to “adjust” the treatment effects for differences in the covariate, and ANCOVA cannot be used to control treatment assignment independent of the covariate (Adams et al., 1985 ; Evans & Anastasio, 1968 ; Lord, 1967 , 1969 ; Miller & Chapman, 2001 ; Tupper & Rosenblood, 1984 ).”
A cross‐cultural comparison of road traffic risk perceptions, attitudes towards traffic safety and driver behaviour (2011, background): “Miller and Chapman ( 2001 ) argued that an analysis of covariance could be an inappropriate statistical method when the groups differ substantially on the included covariates (i.”
Gendered Racism, Coping, Identity Centrality, and African American College Women’s Psychological Distress (2016, background): “In addition, from a theoretical standpoint, problems occur when a demographic variable shares meaningful variance with another variable of theoretical interest (Little, An, Johanns, & Giordani, 2000; Miller & Chapman, 2001; Thompson, 1992).”
Do Bilinguals Have an Advantage in Theory of Mind? A Meta-Analysis (2018, result): “This secondary analysis, however, should be interpreted with caution, given that these studies may have violated assumptions of the Analysis of Covariance (Miller and Chapman, 2001; Paap et al., 2015).”
Bilingual advantages in executive functioning either do not exist or are restricted to very specific and undetermined circumstances. (2015, background): “As Paap, Johnson, and Sawi (2014) discussed a critical assumption of ANCOVA is that the covariate and groups are independent (Miller & Chapman, 2001).”
Young adult outcome of hyperactive children: adaptive functioning in major life activities. (2006, background): “To do so requires, however, that the covariate not be dependent on or related to the independent variable (Miller and Chapman, 2001).”
Differential Effects of Rumination and Dysphoria on the Inhibition of Irrelevant Emotional Material: Evidence from a Negative Priming Task (2006, neutral): “The use of ANCOVAs to control for between-group differences has been criticized (Miller & Chapman, 2001).”
