Summary of mediation model hypothesis 1–3 (a–b).

Model	Maternal Sensitivity (M)	Maternal Trauma (X)	Infant Temperament (Y)
Hypothesis 1a	Total Frequency	Past Year Impairment	Surgency/Reactivity
Hypothesis 1b	Total Frequency	Exposure	Surgency/Reactivity
Hypothesis 2a	Total Frequency	Past Year Impairment	Negative Affectivity
Hypothesis 2b	Total Frequency	Exposure	Negative Affectivity
Hypothesis 3a	Total Frequency	Past Year Impairment	Regulation/Orienting
Hypothesis 3b	Total Frequency	Exposure	Regulation/Orienting

Note. M = mediation variable, X = predictor variable, Y = outcome variable. M was proposed to mediate the relationship between X and Y.
