These findings indicate that delaying intervention with the Lidcombe Program for 1 year after onset, within the preschool years, is unlikely to jeopardize responsiveness to treatment. The clinical implications of these findings are discussed.
Circle of Security is an attachment theory based intervention that aims to promote secure parent-child attachment relationships. Despite extensive uptake of the approach, there is limited empirical evidence regarding efficacy. The current study examined whether participation in the 20-week Circle of Security intervention resulted in positive caregiver-child relationship change in four domains: caregiver reflective functioning; caregiver representations of the child and the relationship with the child; child attachment security, and attachment disorganization. Archived pre- and postintervention data were analyzed from 83 clinically referred caregiver-child dyads (child age: 13-88 months) who completed the Circle of Security intervention in sequential cohorts and gave permission for their data to be included in the study. Caregivers completed the Circle of Security Interview, and dyads were filmed in the Strange Situation Procedure before and after the intervention. Results supported all four hypotheses: Caregiver reflective functioning, caregiving representations, and level of child attachment security increased after the intervention, and level of attachment disorganization decreased for those with high baseline levels. Those whose scores were least optimal prior to intervention showed the greatest change in all domains. This study adds to the evidence suggesting that the 20-week Circle of Security intervention results in significant relationship improvements for caregivers and their children.
This study examined the efficacy of the attachment-based Circle of Security 20-week intervention in improving child behavioural and emotional functioning. Participants were 83 parents of children (1-7 years) referred to a clinical service with concerns about their young children's behaviour. Parents (and teachers, when available) completed questionnaires assessing child protective factors, behavioural concerns, internalizing and externalizing problems, prior to and immediately after the intervention. The following were considered as potential moderators: child gender and age, parent representations, reflective functioning, child attachment indices and severity of presenting problems, prior to treatment. Results showed significant improvement for parent ratings of child protective factors, behavioural concerns, internalizing and externalizing symptoms, all ps < .05, and children with more severe problems showed most improvement. Teachers also reported improvements, but change was significant only for externalizing problems (p = .030). Findings suggest Circle of Security is effective in improving child behavioural and emotional functioning in clinically referred children aged 1-7 years.
This study examined the effectiveness of the attachment-based Circle of Security 20-week intervention (COS) in improving parent emotional functioning in 83 families referred to a community clinical service with concerns about their young children's behavior. Parenting stress and parent psychological symptoms were assessed pre and post intervention and mixed design repeated measures ANOVAs were used to assess change. Severity of presenting problems was considered as a moderator. Results showed clinically significant improvements in both aspects of parent emotional functioning, with changes accounted for by for those with more severe problems at the outset. Improvements for parents were associated with improved child behavior and more positive parent representations of the child and of parenting capacity. Findings suggest the intensive COS intervention is effective in reducing parenting stress and psychological symptoms in parents of children from aged 1-7 years. Questions remain about the mechanisms of change and the direction of effects.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
