摘要

Purpose

Externalizing behavior forms a serious risk factor for adverse outcomes among both adolescents with and without mild intellectual disabilities or borderline intellectual functioning (MID-BIF). Interventions for adolescents with externalizing behavior need further optimization, as current effect sizes are only small to moderate and adolescents with MID-BIF are often excluded from CBT interventions and research into these interventions. The goal of the current study was to increase our understanding of social information processing (SIP) as a potential mechanism in CBT interventions for adolescents with and without MID-BIF and externalizing behavior.

Methods

Eighty-four adolescents with (n = 42) and without (n = 42) MID-BIF (Mage = 14.61, SDage = 1.54; 57.1% males) received an individual experimental CBT-intervention aimed at reducing externalizing problems. Assessment of SIP and externalizing behavior took place before and after the intervention.

Results

Both adolescents with and without MID-BIF perceived themselves to be more competent to exhibit assertive responses after the intervention compared to baseline. Moreover, externalizing behavior decreased over the course of the intervention, although this differed across informants. According to adolescent self-reports, these reductions were smaller among adolescents with MID-BIF compared to those without MID-BIF. In contrast, observers reported reductions in externalizing behavior among adolescents with MID-BIF, but not among those without MID-BIF. Changes in SIP were not related to changes in externalizing behavior, irrespective of whether adolescents did or did not have MID-BIF.

Conclusions

Our findings suggest that changes in SIP were largely the same for adolescents with and without MID-BIF, although findings for changes in externalizing behavior were less conclusive. These findings highlight the promise of using CBT for youth with MID-BIF. Future research could investigate other potential CBT-driven mechanisms of change underlying externalizing behavior of different groups of individuals.
