Expressed emotion as an assessment of family environment with mothers and fathers of 1-year-old children

Early infant prefrontal gray matter volume is associated with concurrent and future infant emotionality

High levels of infant negative emotionality (NE) are associated with emotional and behavioral problems later in childhood. Identifying neural markers of high NE as well as low positive emotionality (PE) in infancy can provide neural markers to aid early identification of vulnerability, and inform interventions to help delay or even prevent psychiatric disorders before the manifestation of symptoms. Prefrontal cortical (PFC) subregions support the regulation of NE and PE, with each PFC subregion differentially specializing in distinct emotional regulation processes. Gray matter (GM) volume measures show good test-retest reliability, and thus have potential use as neural markers of NE and PE. Yet, while studies showed PFC GM structural abnormalities in adolescents and young adults with affective disorders, few studies examined how PFC subregional GM measures are associated with NE and PE in infancy. We aimed to identify relationships among GM in prefrontal cortical subregions at 3 months and caregiver report of infant NE and PE, covarying for infant age and gender and caregiver sociodemographic and clinical variables, in two independent samples at 3 months (Primary: n = 75; Replication sample: n = 40) and at 9 months (Primary: n = 44; Replication sample: n = 40). In the primary sample, greater 3-month medial superior frontal cortical volume was associated with higher infant 3-month NE (p < 0.05); greater 3-month ventrolateral prefrontal cortical volume predicted lower infant 9-month PE (p < 0.05), even after controlling for 3-month NE and PE. GM volume in other PFC subregions also predicted infant 3- and 9-month NE and PE, together with infant demographic factors, caregiver age, and/or caregiver affective instability and anxiety. These findings were replicated in the independent sample. To our knowledge, this is the first study to determine in primary and replication samples associations among infant PFC GM volumes and concurrent and prospective NE and PE, and identify promising, early markers of future psychopathology risk.

The effect of maternal depression on mental representations and child negative affect

BACKGROUND

Maternal depression is a widely recognized public health concern with significant implications for child functioning, including the development of negative child affect and risk for later depression. Negative mental representations may partially account for the association between maternal depression and child negative affect.

METHODS

The effect of depression on low-income mothers' representations of their child, self, and mother was assessed via Expressed Emotion (EE) during Five-Minute Speech Samples. Direct and indirect pathways between maternal depression, EE, and child negative affect were examined. Mothers (M = 24 years old) who had experienced a major depressive episode (n = 144) since child's birth, non-depressed comparison mothers (n = 62), and their children participated.

RESULTS

Examination of between-group differences revealed that depressed mothers had higher levels of overall self EE. Trend results also suggest depressed mothers may have higher overall EE toward their children and their own mothers. Novel coding systems for EE toward self (Identity and Depressotypic Cognitions) and EE toward mother (Source of Concrete Support and Resolution of Past Adversity) were also developed and tested. A significant indirect relation was found between maternal baseline depression and child negative affect at 26 months via the mother's level of EE-Criticism of her mother.

LIMITATIONS

Certain EE subcodes may need to be adapted for young children and high-risk, low-income participants.

CONCLUSIONS

Findings highlights the importance of relational interventions that focus on maternal representations for women with depression and their children.

Parental depressive symptoms, children's emotional and behavioural problems, and parents' expressed emotion-Critical and positive comments

This longitudinal study examined whether mothers' and fathers' depressive symptoms predict, independently and interactively, children's emotional and behavioural problems. It also examined bi-directional associations between parents' expressed emotion constituents (parents' child-directed positive and critical comments) and children's emotional and behavioural problems. At time 1, the sample consisted of 160 families in which 50 mothers and 40 fathers had depression according to the Structured Clinical Interview for DSM-IV. Children's mean age at Time 1 was 3.9 years (SD = 0.8). Families (n = 106) were followed up approximately 16 months later (Time 2). Expressed emotion constituents were assessed using the Preschool Five Minute Speech Sample. In total, 144 mothers and 158 fathers at Time 1 and 93 mothers and 105 fathers at Time 2 provided speech samples. Fathers' depressive symptoms were concurrently associated with more child emotional problems when mothers had higher levels of depressive symptoms. When controlling for important confounders (children's gender, baseline problems, mothers' depressive symptoms and parents' education and age), fathers' depressive symptoms independently predicted higher levels of emotional and behavioural problems in their children over time. There was limited evidence for a bi-directional relationship between fathers' positive comments and change in children's behavioural problems over time. Unexpectedly, there were no bi-directional associations between parents' critical comments and children's outcomes. We conclude that the study provides evidence to support a whole family approach to prevention and intervention strategies for children's mental health and parental depression.

Self-Compassion and Parenting in Mothers and Fathers with Depression

Depression in parents impairs parenting and increases the risk of psychopathology among their children. Prevention and intervention could be informed by knowledge of the mechanisms that break the inter-generational transmission of psychopathology and build resilience in both parents and their children. We used data from two independent studies to examine whether higher levels of self-compassion were associated with better parenting and fewer emotional and behavioral problems in children of parents with a history of depression. Study 1 was a pilot trial of mindfulness-based cognitive therapy that included 38 parents with recurrent depression. Study 2 was a longitudinal study that consisted of 160 families, including 50 mothers and 40 fathers who had a history of depression. Families were followed up approximately 16 months after the first assessment (time 2; n = 106 families). In both studies, self-compassion was assessed with the Self-Compassion Scale. Parents reporting higher levels of self-compassion were more likely to attribute the cause of their children’s behavior to external factors, were less critical, and used fewer distressed reactions to cope with their children’s emotions. Parents’ self-compassion was longitudinally associated with children’s internalizing and externalizing problems, but these associations became nonsignificant after controlling for child gender, parent education, and depressive symptoms. Future larger scale and experimental designs need to examine whether interventions intended to increase self-compassion might reduce the use of negative parenting strategies and thereby the inter-generational transmission of psychopathology.
