“…Previous studies reporting that adolescents differ from older mothers with respect to caregiving and interaction styles ͑Garcia Coll, Hoffman, & Oh, 1987͒, verbal stimulation ͑Culp, Appelbaum, Osofsky, & Levy, 1988͒, attachment to infant ͑Carlson, Labarba, Sclafani, & Bowers, 1986Osofsky, Hann, & Peebles, 1993͒, and separation anxiety ͑Blunk & Williams, 1999͒ suggest that maternal factors could be possible mechanisms to account for past findings of poorer cognitive attainment in the offspring of adolescents ͑Baldwin & Cain, 1980;Belmont, Cohen, Dryfoos, Stein, & Zayac, 1981;Kinard & Klerman, 1983;Pomerleau, Scuccimarri, & Malcuit, 2003͒. As the mother's age alone does not account for poorer development in infants of adolescents ͑Carlson et al, 1986;Garcia Coll, Vohr, Hoffman, & Oh, 1986͒, the impact of other maternal factors needs to be considered.…”
