PURPOSE: To analyze the factors influencing students to choose residen
cy training in primary care (internal medicine, family medicine, and p
ediatrics) or nonprimary care specialties and study the combined effec
t of reported responses on their choice. MATERIALS AND METHODS: A 12-i
tem questionnaire using a 7-point Likert scale was mailed to the 1,164
graduating seniors from 9 medical schools in 1991. Responses ranged f
rom 1, very negative influence, to 7, very positive influence. Four in
dicated no influence. The overall response rate was 69%. Univariate an
alysis of factors associated with specialty choice was done with the M
antel-Haenzsel chi-square test. Odds ratios were calculated for each s
ignificant variable without controlling for other variables. Factors f
ound to have univariate significance were then tested for combined sig
nificance with logistic regression analysis. The regression was perfor
med on a randomly chosen training sample, and validated on a test samp
le. RESULTS: Forty-five percent of respondents chose an internship and
planned residency training in a primary care specialty. Factors that
remained positively associated with choosing a primary care specialty
when controlling for other factors were desire to provide comprehensiv
e care, to keep options open, and to undertake ambulatory care. Desire
for monetary reward was negatively associated with choice of a primar
y care specialty. CONCLUSIONS: Positive educational experiences in the
ambulatory setting should be enhanced, and disparity in remuneration
among disciplines reduced.
