Insights
Early interventions significantly enhance attachment security and reduce disorganized attachment in children. These programs also show effectiveness in improving maternal sensitivity, supporting positive early development.
Area of Science:
- Developmental Psychology
- Child Psychiatry
- Family Studies
Background:
- Attachment security and parental sensitivity are crucial for child development.
- Early interventions aim to support caregivers and improve parent-child relationships.
- Previous research suggests positive outcomes for early intervention programs.
Purpose of the Study:
- To systematically review and meta-analyze randomized controlled trials (RCTs) on early interventions.
- To assess the effectiveness of interventions in improving attachment security and parental sensitivity.
- To synthesize evidence from studies conducted with children under 36 months of age.
Main Methods:
- Systematic review and meta-analysis of RCTs published from 2002-2015.
- Inclusion of interventions delivered to mothers, fathers, or carers via 1:1 support, group work, or guided self-help.
- Data analysis using Mantel-Haenszel odds ratio for dichotomous data and standardized mean differences for continuous data.
Main Results:
- Four studies met the inclusion criteria, categorized into North American/Canadian and South African groups.
- Combined data indicate that early interventions improve attachment security and reduce disorganized attachment.
- One study demonstrated improved maternal sensitivity at 6 and 12 months post-intervention.
Conclusions:
- Early interventions are effective in enhancing children's attachment security.
- These programs positively impact rates of disorganized attachment.
- Evidence supports the efficacy of early interventions in improving maternal sensitivity, consistent with prior reviews.
Abstract:
A systematic review and meta-analysis of randomized controlled trials (RCT) was conducted to determine whether early interventions are effective in improving attachment security and parental sensitivity. Electronic databases were searched 2002-2015 onwards, All RCTs delivered to mothers, fathers or carers, before their child's mean age was 36 months, via 1:1 support, group work or guided self-help were included. The search was restricted to English Language publications. Study Selection, data extraction and quality appraisal were independently undertaken by two authors. With regard to analysis, where appropriate, dichotomous data were pooled using the Mantel- Haenszel odds ratio method and for continuous data descriptive statistics were collected in order to calculate standardized mean differences and effect sizes. Four studies met inclusion criteria and were divided into two groups: North American & Canadian and South African based studies. Combining data from both groups indicates that early interventions improve attachment security and improves rates of disorganized attachment. One study provided extractable data on the outcome of parental sensitivity which shows that early interventions were effective in improving maternal sensitivity at 6 and 12 months. Study results generally support the findings of a previous review (Bakermans-Kranenburg et al., 2003) which found that early interventions improved attachment security and maternal sensitivity.
