Insights
Older sibling mentalization acts as a protective factor. It buffers younger siblings against familial risk for internalizing problems, preventing the development of future internalizing symptoms when mentalizing abilities are present.
Area of Science:
- Developmental Psychology
- Child Psychology
- Family Studies
Background:
- Internalizing problems in children are a significant concern.
- Familial risk factors can increase the likelihood of developing internalizing symptoms.
- The role of sibling relationships in child development is increasingly recognized.
Purpose of the Study:
- To investigate if older sibling mentalization moderates the link between familial risk and internalizing problems in younger siblings.
- To examine older sibling's capacity to understand mental states (mentalization) as a potential protective factor.
- To explore the developmental trajectory of internalizing problems in relation to family risk and sibling interaction.
Main Methods:
- Longitudinal study with 397 older siblings and their younger siblings (target children).
- Assessment of familial risk via older siblings' internalizing problems.
- Observation and coding of older sibling mentalization during pretend-play interactions.
- Measurement of target children's internalizing problems using parent reports at two time points.
Main Results:
- A significant interaction was found between familial risk and older sibling mentalization.
- Familial risk predicted target children's internalizing problems only when older sibling mentalization was low.
- When older siblings demonstrated mentalizing abilities, familial risk was not associated with target children's internalizing problems.
Conclusions:
- Older sibling mentalization serves as a crucial protective factor against the development of internalizing problems.
- Interventions aimed at enhancing sibling mentalization may help mitigate risks associated with familial psychopathology.
- The sibling relationship, specifically the older sibling's mentalizing capacity, plays a vital role in younger sibling's socio-emotional development.
Abstract:
The current study explored whether older sibling mentalization moderated the relationship between familial risk for internalizing symptoms and the development of future internalizing problems in the younger siblings, referred to as target children. Data were collected on 397 older siblings at Time 1 (T1) when target children were newborn and their older siblings were on average 2.61 years old (SD = .75). Target children were on average 1.60 years old at Time 2 (T2). Internalizing problems were assessed via mother and partner reports. Familial risk was operationalized as the average of all older siblings' level of internalizing problems. Older sibling mentalization, indexed by internal state talk and reasoning, was observed and coded during a sibling pretend-play interaction at T2. Results revealed a significant interaction between familial risk of internalizing problems and older siblings' mentalizing abilities, showing that familial risk was related to target children's internalizing problems in the absence of sibling mentalization. Familial risk was not associated with target children's internalizing problems when siblings demonstrated mentalizing abilities. Findings support the need to consider sibling mentalization as a protective factor for children's internalizing problems. (PsycINFO Database Record
