The authors examined parent and child ratings of somatic complaints in 65 children with Attention-Deficit/Hyperactivity Disorder (ADHD) who received four doses (5 mg, 10 mg, 15 mg, 20 mg) of methylphenidate (MPH) in the context of a double-blind, placebo controlled, within-subject (crossover) experimental design.
Results indicated that parent and child ratings of somatic complaints decreased in a linear fashion from baseline levels as a function of increasing MPH dose and showed minimal variation across MPH conditions. Statistical comparisons of specific somatic complaints indicated minimal agreement between parents and children in contrast to the nearly identical parent-child dose-response curves. The paradoxical findings of fewer somatic complaints associated with MPH, importance of obtaining children's perceptions of MPH treatment, and Implications for measuring somatic complaints are discussed.
