Sibling-comparison and longitudinal designs survived the reverse-causality critique

Evidence

The 2019 APA Resolution on Physical Discipline of Children by Adults states: “The APA calls upon parents to use alternative forms of discipline that are not physically punitive” and “opposes the use of physical discipline as a behavior management strategy for children and adolescents.” … The 2019 resolution also drew on Gershoff’s 2018 paper in the American Psychologist — a paper that addressed the causality question directly. The persistent critique of the adverse-association literature was methodological: most studies were observational; most could not rule out the possibility that difficult child behavior caused more punishment rather than punishment causing difficult behavior. The 2018 paper, co-authored by seven leading developmental psychologists, reviewed the subset of studies designed to address that critique — prospective longitudinal designs, sibling-comparison designs that controlled for family-level confounders, studies that measured child behavior before and after punishment episodes and tracked the direction of effect. The finding was consistent: the adverse associations persisted across methodologies designed to test the causality claim. The evidence for causal harm was not definitive in the sense that randomized control trials would be definitive — you cannot randomly assign children to physical punishment — but it met the evidentiary standard applied in comparable public health domains. — , The Rod and the Child, 6733
