Insights
High emotionality, not attachment, predicts psychopathology in children of parents with bipolar disorder (BD). This finding suggests emotionality may be a risk factor for mental health issues in high-risk youth.
Area of Science:
- Child and Adolescent Psychiatry
- Developmental Psychology
- Psychopathology Research
Background:
- Attachment styles are linked to mood disorders and temperament.
- Associations between attachment, temperament, and psychopathology in children with a parent with bipolar disorder (BD) are not well understood.
- This study examines these relationships in high-risk (HR) offspring.
Purpose of the Study:
- To investigate the association between attachment, temperament, and psychopathology in children with a parent with BD.
- To compare high-risk (HR) offspring with control (C) offspring.
Main Methods:
- Prospective cohort study design.
- Annual clinical assessments using KSADS-PL interviews for HR and C offspring.
- Validated self-report measures of perceived attachment and temperament were administered.
Main Results:
- Perceived attachment did not differ between HR and C offspring.
- Attachment did not predict psychopathology or mood disorder.
- High emotionality significantly predicted increased risk of psychopathology (hazard ratio=1.36) and mood disorder (hazard ratio=1.24) in HR offspring.
Conclusions:
- Attachment may not be grossly abnormal in HR offspring compared to controls.
- The role of emotionality as a barometer of illness or a true risk factor requires further investigation.
- Longitudinal research is needed to understand psychosocial risk factors in BD development and inform early interventions for HR youth.
Introduction:
Attachment is associated both with the risk of developing a mood disorder and temperamental profile. Relatively little is known about these associations in children of a parent with bipolar disorder (BD). The present study is a preliminary analysis of the association between attachment, temperament and psychopathology among high-risk offspring.
Methods:
As part of an ongoing prospective cohort study, offspring from families with one parent with BD (HR) and offspring from families with unaffected parents (C) were clinically assessed using KSADS-PL format interviews annually. Validated self-report measures of perceived attachment and temperament were completed.
Results:
Perceived attachment did not differentiate HR from C offspring and did not predict psychopathology or mood disorder in particular. However, high emotionality significantly predicted the risk of psychopathology in HR offspring, where 1 standard deviation increase in emotionality significantly increased the hazard of psychopathology by a factor of 1.36 (p=0.0009) and mood disorder by a factor of 1.24 (p=0.02).
Limitations:
Use of retrospective measures and low sample size for some models.
Conclusions:
There may be no gross abnormalities in attachment among HR compared to C offspring. It remains unclear if emotionality is a barometer of illness or a true risk factor in this population. More longitudinal research is needed to advance understanding of the influential pathways by which psychosocial risk factors impact the development of BD. This research has implications for targeted early interventions in HR youth.
