Impact of a Brief Group Intervention to Enhance Parenting and the Home Learning Environment for Children Aged...

Area of Science:

• Child Development
• Family Studies
• Educational Psychology

Background:

• Disadvantaged families often have less-resourced home learning environments.
• Parenting interventions can strengthen these environments and support child development.
• Effectiveness varies by age group and intervention intensity.

Purpose of the Study:

• To evaluate a group parenting intervention's effectiveness in enhancing the home learning environment for children from disadvantaged families.
• To compare a standard group intervention with an enhanced version including home coaching.
• To assess outcomes for parents of infants and toddlers separately.

Main Methods:

• Two parallel cluster randomized controlled trials were conducted for infants (6-12 months) and toddlers (12-36 months).
• Intervention arms included: smalltalk group-only, smalltalk plus (group + home coaching), and standard care controls.
• Primary outcomes (parent verbal responsivity, home learning activities) were measured at baseline, 12, and 32 weeks.

Main Results:

• The infant trial showed no significant differences in primary outcomes between trial arms at 32 weeks.
• For toddlers, the smalltalk group-only intervention improved parent verbal responsivity (ES=0.16) and home learning activities (ES=0.17) compared to standard care.
• The enhanced 'smalltalk plus' intervention did not yield significant primary outcome improvements for toddlers, though secondary outcomes showed sustained benefits.

Conclusions:

• A group parenting intervention shows modest benefits for the home learning environment of toddlers but not infants.
• The 'smalltalk' intervention may be effective for toddlers, particularly the group-only format.
• Further research is needed to understand the differential effects across age groups and intervention components.
