Table 2.

Frequency, rate, and duration of three types of Developmental Care (M (SD)) activities (All Developmental Care, Kangaroo Care, Swaddled Holding) performed by mothers who did not complete mental health screening (Non-Screened; n = 80) versus two groups of mothers who completed mental health screening (non-clinically elevated; n = 36; clinically-elevated; n = 19).

	Non-Screened	Screened
		Non-Clinically Elevated	Clinically Elevated	F	p
All Dev Care
Frequency	1.2 (0.8)	1.2 (0.8)	1.3 (0.5)	0.15	0.86
Rate	61.5 (43.2)	61.6 (49.6)	66.7 (28.0)	0.12	0.89
Duration	51.7 (10.0)	50.2 (10.0)	51.8 (8.2)	0.34	0.71
Kangaroo Care
Frequency	0.2 (0.2)	0.2 (0.2)	0.2 (0.1)	0.85	0.43
Rate	17.6 (18.5)	14.0 (12.6)	17.1 (10.3)	0.64	0.53
Duration	69.6 (14.9)	71.2 (15.7)	77.4 (21.2)	1.72	0.18
Swaddled Holding
Frequency	0.5 (0.4)	0.5 (0.5)	0.5 (0.3)	0.01	0.99
Rate	33.1 (27.2)	35.3 (36.3)	34.5 (17.7)	0.08	0.93
Duration	63.1 (11.9)	65.6 (10.2)	67.3 (12.5)	1.32	0.27

For Frequency and Rate df = (2, 132); for Duration, df = (2, 129). Frequency = Total number of instances divided by number of days of hospitalization; Rate = Total minutes divided by number of days of hospitalization; Duration = Total minutes divided by total number of instances.
