Utilizing data from a pilot sample, 54 infants and their mothers
(18 depressed and 36 non-depressed) were examined during a play interaction
and during feeding session when the infants were 1 and 3 months of
age. In order to be classified as depressed, mothers reported more depressive
symptoms on a self-report depression scale (Center for Epidemiological
Studies, Depressions Scale, CES-D, (Radloff, 1977) score of ≥ 16) and also
met criteria for dysthymia or major depressive disorder within an interview (Diagnostic Interview Schedule, DIS, Robins et al., 1981)
