Physician early intervention referral as a function of child age and level of developmental delay.

A 2 x 2 factorial design was used to examine the effects of child age (20 and 40 months) and level of developmental delay (mild and severe) on requests for consultations and referrals. Significant main effects for age and level of delay were found. Requests for education and psychological consultations were in the low to moderate range, and one fourth of the respondents were not likely to make a school referral. Implications for future research and continuing medical education were discussed.
