The present study investigated the relationship between Attention Deficit Hyperactivity Disorder (ADHD) symptoms and insecure attachment styles. The results of a meta-analysis will be provided to clarify a possible link between ADHD and attachment and to establish the effect size. Practitioners will learn of the degree to which ADHD symptoms correspond with attachment insecurity and whether the results of this study provide support for the efficacy of attachment-based interventions for this population.
