This case study report of diagnostic psychological testing considers the implications of a 53-point verbal-performance IQ differential, with the benefit of neuropsychological and neuroradiologic imaging studies, a 6-month follow-up Wechsler Adult Intelligence Scale-Revised (WAIS-R; Wechsler, 1981) evaluation, and retrospective examination of early school records and test findings. The approach highlights the limitations of cross-sectional clinical studies in differential diagnosis, particularly when both psychodynamic and neuropsychological factors are at issue. This report demonstrates how an early acquired neurodevelopmentally based deficit can alter or restructure the appearance of adult cognitive-perceptual functions. Further, early neurodevelopmental impairment is considered from the standpoint of its influence on compromised autonomous ego functions.

OBJECTIVE: To estimate the reliability of data obtained from questionnaires applied to adolescents and their mothers in a health survey. METHODS: Data from population-based survey conducted with a one-stage random cluster area sampling of residents in the urban area of Salvador, Brazil, were assessed. The study sample comprised 82 pairs of adolescent workers aged 10 to 14 years and their mothers. After interviewing the adolescents, in a second visit, their mothers were invited to answer a similar questionnaire applied by a blinded interviewer. Respiratory and depressive symptoms, sleep pattern changes and distress in the neighborhood and at school were the variables analyzed. Reliability was measured using proportion of agreements and kappa index of agreement statistics. RESULTS: Overall agreement and kappa index were low. Mothers have provided more positive answers than adolescents, resulting in a negative bias. Reliability was higher among boys for all answers when compared to girls, except for sleep patterns changes. For depressive symptoms, mother's education level was negatively associated with agreement for both genders. CONCLUSIONS: Information from adolescents differs from that obtained from mothers. It is worth noticing that poor agreement does not impair validity, which needs to be examined in further studies.
