Sources of information used in diagnosing childhood learning disabilities.
One hundred nineteen questionnaires in which board certified/eligible child neurologists were asked to rank the diagnostic importance of 8 sources of information commonly used in the assessment of children with learning disabilities were analyzed by the Wilcoxon matched-pairs signed ranks test. All pairwise comparisons of the 8 sources revealed significant differences (P less than or equal to .033) except for psychologic reports (mean rank +/- 1 S.D. = 2.09 +/- 1.14) and medical histories (2.26 +/- 1.45) which were rated equal (P = .397) and, compared to the other sources, diagnostically most useful (P less than .0001). Analysis of the 6 remaining sources demonstrated the following: teachers' reports (3.39 +/- 1.35) were deemed more helpful than the mental status examination (3.92 +/- 1.61; P = .033) and questionnaires distributed to parents and teachers (5.05 +/- 2.11) were more useful than findings on the remainder of the neurologic examination (5.81 +/- 1.46; P = .012). Social service reports (6.45 +/- 1.32) took precedence over soft signs (7.12 +/- 1.05; P = .001) which were considered the least diagnostically helpful. Analysis of variance revealed that this rank order was relatively independent of the responders' age, type of practice, years elapsed since completion of training and percentage of professional time spent examining pediatric patients. Information derived from outside sources (collective mean rank +/- 1 S.D. = 4.25 +/- 0.9) contributed significantly more to the diagnosis of learning disabilities than to information elicited directly by the examining neurologists (4.77 +/- .88; P = .002).(ABSTRACT TRUNCATED AT 250 WORDS)
