Table 3. Results of LMMs conducted for model set 2 and model set 3.

Model set 2a Model set 3b
Mother follow Time on nipple Distress vocalization SDB fGCM concentration
Maternal rejection NS P < 0.001 P < 0.001 NS P = 0.023
Mother follow P = 0.036 NS NS P = 0.055

SDB NS

SDB: self-directed behaviour; fGCM: faecal glucocorticoid metabolite.

a

Models tested for relationships between independent behavioural variables (i.e. mother–infant interactions and behavioural indicators of infant anxiety).

b

Models tested whether fGCM concentration (dependent variable) varied with respect to maternal interaction variables or behavioural indicators of anxiety (independent variables).
