ABSTRACT
This study investigated whether oppositional defiant disorder (ODD) with the DSM-5 limited prosocial emotions (LPE) specifier marks a more severe clinical presentation than ODD alone. Mothers, fathers, and teachers of 2,142 Spanish children (49.49% girls; ages 8 to 13 years) completed measures of ODD, LPE, ADHD-hyperactivity/impulsivity (HI), ADHD-inattention (IN), cognitive disengagement syndrome (CDS), anxiety, depression, social impairment, academic impairment, and peer rejection (teacher only measure). Scores greater or less than 1.50 SDs above the ODD and LPE means were used to create ODD-only (5.89-7.22% of the sample, depending on informant), LPE-only (7.61-8.25%), ODD + LPE (1.69-2.20%), and comparison groups (82.96-84.68%) for each source. For all three sources, the LPE-only group scored higher than the comparison group on social impairment, peer rejection, and academic impairment but did not differ significantly on anxiety. Although the ODD-only and ODD + LPE groups scored higher than the LPE-only group on all symptom and most impairment dimensions, the ODD + LPE group did not show a consistent pattern of higher scores than the ODD-only group. There were no differences on mother ratings, and higher scores for the ODD + LPE group emerged on only three of seven father-report measures (depression, CDS, and ADHD-IN) and three of eight teacher-report measures (peer rejection, social impairment, and academic impairment). Limited differences between the ODD + LPE and ODD-only groups raise questions about the usefulness of LPE as a severity specifier for ODD among children. Future studies need to address this issue with adolescents and clinical samples.
