Biofeedback treatment for pediatric migraine: prediction of treatment outcome

Despite a growing number of studies showing good effectiveness of nonpharmacological treatments such as thermal biofeedback (TBF) for pediatric migraine, little is known about psychosocial variables that might be predictive of treatment outcome. The identification of predictors appears especially important when children are treated in a home-based treatment format that tends to be somewhat less effective than a therapist-administered treatment. A total of 32 children between the ages 8 and 16 years completed a home-based TBF treatment program with treatment outcome being of similar magnitude as previously reported in the literature. Multiple regression analysis revealed externalizing behavior tendencies, initial level of psychosomatic complaints, and the child's age to be highly predictive of outcome, whereas dimensions of family functioning failed to exert a direct influence. The implications of these findings for the development and evaluation of future treatment programs are discussed.
