Objective To examine the effect of parental training on disturbed behavior of early childhood cases presented to the pediatricians. Methods The patients who reported in pediatric OPD of the Himalayan Institute of Medical Sciences, Dehradun, with complaints of low learning, poor memory, vertigo, speech problem, stress, headache, depression, adjustment problems, aggression, and hostile behavior were included in the study. Children aged 3 through 6 (N = 60), were screened through PBQ (Preschool Behavior Questionnaire), DST (developmental screening Test), and Vineland Social Maturity Scale (VSMS). Children included in the study had an average range of developmental quotient 85–90 (mean DQ = 87.5). Range of social quotient was 40–45 (mean SQ = 42.5). Twenty four fortnightly sessions of ‘parental training’ using the model of ‘Mindful Parenting’ were conducted. Single group t test method was applied in order to see the difference in mean of pre and post assessment of PBQ. Results After concluding parental training (after 24 sessions), mean difference of total disturbed behavior was found to be significant (t value: 5.31 > .05) Similarly, the mean difference of hostile/aggressive behavior (t value: 10.2 > .05), anxious behavior (t value: 18.5 > .05), and hyperactive/distractible behavior (t value: 1.97 > .05) were found to be significant. Conclusions These results provide some evidence in favor of parental training in managing behavioral problems occurring in early childhood. Instead of putting the child immediately on medication, parents can get training and prepare a plan to understand and make a change in child’s behavior leading to better health.
