This research addresses preferences and theoretical learnings of prese
nt-day psychiatrists along the continuum defined at one end by biology
and at the other by psychology. A questionnaire was devised and sent
to 5,702 randomly selected members of the American Psychiatric Associa
tion in 1990. The response rate was 30.7%. The results were analyzed f
or two groups: psychiatrists with fewer than 15 years of practice sinc
e residency and psychiatrists with more than 15 years of practice sinc
e graduation. Although the great majority of psychiatrists in both gro
ups equally valued psychology and biology, the senior group attributed
a greater importance to psychological methods, whereas the younger gr
oup stressed equally the importance of biology and psychology. This su
ggests that psychiatry has evolved over the years from a predominantly
psychological practice to one with a more equal emphasis on psycholog
y and biology. Recent advances in neuroscience may have shifted the pe
ndulum toward a more balanced willingness of clinicians to consider th
e broad armamentarium of psychosocial and biological treatments. The r
esults point to the need for further conceptualization into the relati
onship between biology and psychology and its incorporation into the p
sychiatric residency curriculum.
