In this short-term longitudinal study, the social psychological concept of
"possible selves" was integrated with constructs of adult development to ex
amine differences in aspects of self and parenting among fathers-to-be and
fathers of infants. Men's actual and possible conceptions of self were meas
ured during their wives' last trimester of pregnancy and again when their i
nfants were about 1 year old. Data are reported on 56 first-time fathers wh
o completed pre- and postnatal assessments; main analyses focused on a subs
et of 32 men who completed a postnatal measure of the self. Men's ages rang
ed from 20 to 47 years (M = 30.61, SD = 6.57); most were White (83.5%) and
middle class. Data were collected through interviews and questionnaires. Re
sults indicate that how men view themselves before and after the birth of t
heir Ist child is relevant for understanding their motivation for role chan
ge, their own psychological well-being, and their involvement with their in
fant.
