Trajectories of maternal depressive symptoms, maternal sensitivity, and children's functioning at school entry

Using data from the National Institute of Child Health and Human Development Study of Early Child Care and Youth Development, the authors modeled trajectories of maternal depressive symptoms from infant age 1 month to 7 years. The authors identified 6 trajectories of maternal depressive symptoms: high-chronic, moderate-increasing, high-decreasing, intermittent, moderate-stable, and low-stable. Women on these depression trajectories varied in sociodemographic risk and in changes in observed maternal sensitivity over time. Maternal sensitivity was generally higher and increased when depressive symptoms were low; sensitivity was lower and decreased when depressive symptoms were either high or increasing. Child outcomes at 1st grade were examined by trajectory group. The authors discuss the complexity of disentangling maternal symptoms from maternal sensitivity and sociodemographic risk when predicting children's functioning.     

Predicting toddler anxiety/depressive symptoms: Effects of caregiver sensitivity on temperamentally vulnerable children

This research examines whether maternal sensitivity in early childhood reduces later anxiety/depressive symptoms for children with more temperamental vulnerability, and whether these effects are different for boys and girls. Data from the National Institute of Child Health and Human Development Early Child Care study with 1,226 subjects (631 boys, 595 girls) were analyzed. Mothers and other caregivers rated children's difficult temperament at 1 and 6 months. Trained observers scored maternal sensitivity when children were 6 and 15 months. Child anxiety/depressive symptoms were rated by mothers and other caregivers when children were 2 and 3 years of age. Maternal sensitivity in early childhood significantly predicted decreased 2‐ and 3‐year‐old anxiety/depressive symptoms. Children with more difficult temperament were significantly more likely to show decreased anxiety/depressive symptoms at 2 years of age if their mothers had been more sensitive. Maternal sensitivity also was a significant predictor of decreased anxiety/depressive symptoms for more temperamentally difficult boys, and temperamentally difficult boys with more sensitive mothers were found to be significantly more likely than girls to show decreased anxiety/depressive symptoms at 3 years of age. The findings of this pilot research suggest that facilitating and supporting increased sensitivity for mothers with more temperamentally difficult children could be beneficial. ©2005 Michigan Association for Infant Mental Health.     

Effects of maternal depressive symptoms on sensitivity to infant distress and non-distress: Role of SES and race

The goals of the present study were to examine the extent to which (a) maternal depressive symptoms (prenatal vs. postnatal depressive symptoms) undermine maternal sensitivity toward both infant distress and non-distress; (b) such effects are stronger in the context of socioeconomic risk. SES risk and depressive symptoms interacted such that depressive symptoms, both pre and postnatal, only predicted lower sensitivity among mothers at heightened SES risk. The effects were comparable for sensitivity to distress and non-distress and did not vary by maternal race.     

An examination of the impact of maternal fetal attachment,postpartum depressive symptoms and parenting stress on maternal sensitivity

The current study aimed to examine the impact of maternal depression, maternal fetal attachment (MFA) and parenting stress on maternal sensitivity, intrusiveness and positive regard for the child with a sample of 36 low-income, mothers-infant dyads that were followed from pregnancy through the first year postpartum. Maternal depression and parenting stress were expected to have a negative impact on maternal sensitivity, intrusiveness and positive regard, while high MFA was hypothesized to have a positive impact on these three outcomes. Our data provide partial support for our hypotheses. Findings from this study add to the literature by examining the stability of the maternal prenatal and postpartum bond with her infant as well as by looking at the impact of parenting stress on maternal behaviors and processes that may lead to later attachment security differences, such as maternal sensitivity and responsiveness.     

Infant sleep moderates the effect of infant temperament on maternal depressive symptoms,maternal sensitivity,and family functioning

Observed infant temperamental difficulty and infant sleep efficiency and sleep variability were examined as predictors of maternal depressive symptoms, maternal sensitivity, and family functioning. Eight observations at 8-months postpartum were used to assess infant temperament, and actigraphy was used to measure infant sleep for 1-week at the time of the 8-month assessment. Structured clinical interviews were used to assess maternal depressive symptoms between 5 and 12 months postpartum and at 15 months postpartum, and observational assessments were used to assess maternal sensitivity and family functioning at 15 months postpartum. Variability in infant sleep moderated the effect of infant temperament on maternal depressive symptoms, maternal sensitivity, and family functioning. Infant temperament was positively associated with maternal depressive symptoms when variability in infant sleep efficiency was high, but not when variability in infant sleep efficiency was low. Likewise, infant temperament was negatively associated with maternal sensitivity and family functioning when variability in infant sleep efficiency was high, but not when variability in infant sleep efficiency was low. Results underscore the importance of infant sleep for maternal and family health.     

Predicting adolescent peer problems and antisocial activities: the relative roles of aggression and dysregulation

This study examined the relative roles of aggression and other dysregulated behaviors in the prediction of adolescent peer problems and antisocial behavior. The social adjustment of 145 boys studied first in Grades 3-6 was assessed again 4 years later in Grades 7-10. At each time, peer ratings of aggressive, hyperactive-disruptive, withdrawn, and irritable-inattentive behaviors were collected. Aggression and withdrawal showed stability and were linked to peer difficulties in elementary school and in adolescence, but these behaviors indicated significant risk for adolescent rejection, victimization, and antisocial activity primarily when accompanied by irritable-inattentive behaviors. Results are discussed in terms of the potential role that difficulties regulating negative affect may play in the genesis of the particular constellation of irritable-inattentive behaviors studied here and the developmental significance of aggressive or withdrawn problem profiles that are or are not accompanied by these behavioral indicators of dysregulation.     

Postnatal maternal symptoms of depression and child emotion dysregulation: The mediation role of infant EEG alpha asymmetry

In a community-based sample of 104 infants and their mothers, we hypothesized a pathway from postnatal maternal symptoms of depression to child emotion dysregulation, and tested at 6 months of age the mediation role of alpha asymmetry at frontal and parietal sites. We recorded infant resting-state EEG at 6 months of age. Child emotion dysregulation was measured at 24 months by the Child Behavior Checklist Dysregulation Profile derived from the CBCL 1½-5. Maternal depression symptoms were scored 6 months after the delivery by the Anxious/Depressed scale of the Adult Self-Report. We used structural equation modeling to test the mediation model from maternal depression symptoms to child emotion dysregulation mediated by frontal and parietal alpha asymmetry. The mediation model provided an excellent fit to the data [χ2(3) = 3.088, p = .378; RMSEA = .017, CFI = .1.00; SRMR = 0.040] and explained 23.3% of the variance in child emotion dysregulation. The indirect path via parietal alpha asymmetry was significant (β = .065; SE = .033; 95% CI = .001–.139; p = .048), i.e. greater levels of maternal depression symptoms predicted left parietal alpha asymmetry, which predicted higher levels of child emotion dysregulation. The direct effect, i.e. the pathway linking maternal depression symptoms and child emotion dysregulation above and beyond the indirect effects, was also significant. We found evidence for a partial mediation role of left parietal alpha asymmetry in a longitudinal pathway from postnatal maternal symptoms of depression to child emotion dysregulation, providing support for left parietal asymmetry as an index of biological vulnerability to emotion dysregulation in the first years of life.     

Differential roles of depressive and anxious symptoms and gender in defensiveness

Among a sample of Air Force cadets facing the prospect of basic training (N= 1,190; 1,005 men and 185 women), the influence of a defensive test-taking style on measures of depressive and anxious symptoms was examined. Participants completed the Beck Depression Inventory (Beck & Steer, 1987) and the Beck Anxiety Inventory (Beck, Epstein, Brown, & Steer, 1988), as well as the MMPI (Hathaway & McKinley, 1943) L scale. Results supported hypotheses that defensiveness would affect a self-report measure of depression but not a self-report measure of anxiety and would do so more among men than women. Applied implications of the results are discussed.     

Night waking in 6-month-old infants and maternal depressive symptoms

Relations between night waking in infants and depressive symptoms in their mothers at 6 months postpartum were examined using the data from the National Institute for Child Health and Human Development Study of Early Child Care. Although more depressive symptoms were only weakly correlated with a higher frequency of infant waking, longer wake times, and more total time awake, the rate of clinically significant depression scores was about double in mothers of chronically waking infants in comparison with mothers whose infants did not awaken during the night. The value of comparing subgroups to elucidate relations identified through correlations is discussed.     

Tightly linked systems: reciprocal relations between maternal depressive symptoms and maternal reports of adolescent externalizing behavior

The frequently observed link between maternal depressive symptoms and heightened maternal reporting of adolescent externalizing behavior was examined from an integrative, systems perspective using a community sample of 180 adolescents, their mothers, fathers, and close peers, assessed twice over a 3-year period. Consistent with this perspective, the maternal depression-adolescent externalizing link was found to reflect not simply maternal reporting biases, but heightened maternal sensitivity to independently observable teen misbehavior as well as long-term, predictive links between maternal symptoms and teen behavior. Maternal depressive symptoms predicted relative increases over time in teen externalizing behavior. Child effects were also found, however, in which teen externalizing behavior predicted future relative increases in maternal depressive symptoms. Findings are interpreted as revealing a tightly linked behavioral-affective system in families with mothers experiencing depressive symptoms and teens engaged in externalizing behavior and further suggest that research on depressive symptoms in women with adolescent offspring should now consider offspring externalizing behaviors as a significant risk factor.     

Predicting maternal reactivity/sensitivity: The role of infant emotionality,maternal depressiveness/anxiety,and social support

It was hypothesized that an accumulation of unfavorable conditions, i.e., high negative emotionality and low positive emotionality of the infant, maternal depression and anxiety, and lacking social and emotional support can attenuate mothers' reactivity/sensitivity. Maternal reactivity/sensitivity was observed during home visits and in the laboratory. Infant negative and positive emotionality was assessed by mother reports and behavioral observations. Maternal depressiveness/anxiety as well as social support were assessed via questionnaires. All mothers were primiparous and had healthy infants. Data collection was conducted at the infants' ages of four months (37 dyads) and eight months (33 dyads). The sample consisted of 19 male and 18 female infants (four‐months' measurement). Whereas the presence of a single risk factor was not related to maternal reactivity/sensitivity, the combination was. A decrease in maternal reactivity/sensitivity over the course of time was demonstrated for mothers who had to deal with high negative emotionality of the infant in combination with either high depressiveness/anxiety or low social support at the infants' age of four months. No significant main or interaction effects could be shown for infant positive emotionality. ©2004 Michigan Association for Infant Mental Health.     

Postnatal trajectories of maternal depressive symptoms: Postpartum antecedents and differences in toddler adjustment

Infants are uniquely vulnerable to maternal depression's noxious effects, but few longitudinal studies have tried to identify discrete postnatal trajectories of maternal depressive symptoms (MDS) beginning in infancy. This study extends evidence of heterogeneous change in postnatal MDS by examining their cross-contextual antecedents in infancy and their consequences for children's early behavior problems and language skills in late toddlerhood. A community sample of mother–child dyads (N = 235, 72% Caucasian) was assessed when children were 7, 15, and 33 months old. Mothers reported their socioeconomic status (SES), social support, marital relationship quality, family dysfunction, parenting stress, and infants’ functional regulatory problems at 7 months postpartum, and children's internalizing and externalizing symptoms at 33 months. Children completed a receptive vocabulary assessment at 33 months in the lab. Latent class growth analysis identified three postnatal MDS trajectory classes that fit the data best: low-decreasing, moderate, and increasing. Psychosocial measures at seven months postpartum primarily predicted membership to these postnatal trajectory classes, which subsequently differed in children's internalizing, externalizing, and receptive vocabulary in late toddlerhood, controlling for family SES and functional regulatory problems in infancy. We discuss salient antecedents and consequences of postnatal depression for mothers and their offspring.     

Emotion dysregulation as a partial mediator between reinforcement sensitivity and posttraumatic stress symptoms

The reinforcement sensitivity theory (RST) asserts that three brain subsystems (i.e., the Behavioral Approach System [BAS], the Behavioral Inhibition System [BIS], and the Fight–Flight–Freeze System [FFFS]) underlie individual variations seen in personality and psychopathology. Though revised by Gray and McNaughton (2000), many researchers continue to utilize the original, and now outdated, theory of reinforcement sensitivity. Additionally, while there is an abundance of research investigating the association between reinforcement sensitivity and psychopathology, the underlying mechanisms between these constructs remain largely unknown. Therefore, the aim of the current study was to test whether emotion dysregulation acted as a partial mediator between FFFS sensitivity and posttraumatic stress symptoms (PTSS) under the revised RST framework. Data was collected from 282 undergraduate students at a Midwestern university who experienced at least one potentially traumatic event. Bootstrapping was used to test the significance of the indirect effect (e.g., amount of mediation) of FFFS sensitivity on PTSS. The indirect effect was significant (2000 bootstrapped CI_95 = .11−.25), indicating that emotion dysregulation partially mediated the relationship between FFFS sensitivity and PTSS. More specifically, individuals with high FFFS sensitivity reported higher levels of emotion dysregulation, which in turn was associated with greater PTSS scores.     

Infant sensitivity to negative maternal emotional shifts: Effects of infant sex,maternal postnatal depression,and interactive style

This study examined the effects of infant sex, maternal postnatal depression, and maternal interactive style on infant sensitivity to maternal negative emotional shifts. Face‐to‐face interactions of 68 mother–infant dyads were analyzed at 8 and 18 weeks. Twenty‐five (28%) mothers had postnatal depression. Interactions were analyzed in terms of overall maternal interactive style: “sensitive,” “anxious,” “intrusive,” and “sad.” Episodes of negative shifts in maternal emotional expression were recorded, along with expressions of infant sensitivity to these changes. Daughters of depressed mothers showed higher rates of sensitivity to maternal negative emotion whereas their sons showed lower rates, in comparison to both girl and boy infants of well mothers. While maternal interactive style had no effect on 8‐week infant sensitivity to maternal negative emotional shifts, high rates of 18‐week infant sensitivity were predicted by both an 8‐week and a concurrent, “sad” maternal interactive style. The findings are discussed in relation to theories of emotional and interpersonal development.     

Longitudinal assessment of the low-end specificity of maternal reports of depressive symptoms

Recent studies have raised concerns about the specificity of self-report measures of depression with respect to low-end scores. Because of the high face validity of measures such as the Beck Depression Inventory, it is suspected that extremely low scores may reflect individuals who may harbor depressive symptoms or other psychological abnormalities, yet are inclined to 'fake-good', or respond in a socially desirable manner on the BDI. The presence of this phenomenon was tested in a sample of adolescent mothers who were assessed at four time points over 8 years. It was hypothesized that low-scoring mothers (compared with medium- and high-scoring mothers) would have more negative outcomes on a variety of self-report and observational measures of parenting, as well as have children with more negative outcomes on adjustment and behavior. This study employed multiple assessments, multiple informants and multiple domains of functioning. The analyses controlled for the possible effects of social desirability and demographic differences between the depression groups. The hypotheses were not supported. The majority of analyses found no differences between the groups; where differences did exist, there were no indications that the low-scoring group was at a disadvantage to the medium or high scoring groups.     

Mother-child relationships of children with ADHD: the role of maternal depressive symptoms and depression-related distortions

We investigated the DepressionDistortion hypothesis by examining the effects of maternal depressive symptoms on cross-informant discrepancies in reports of child behavior problems and several measures of parent–child relationship. The sample included ninety-six 6 to 10-year-old children diagnosed with ADHD-Combined Type, and their mothers, who provided baseline data before participating in a randomized clinical trial. Measures incorporated child characteristics, self-reports of maternal depressive symptoms, parenting practices, and laboratory mother–child interactions. Elevations in maternal depressive symptoms were associated with maternal reports of negative parenting style but not with observed laboratory interactions. Mothers' levels of depressive symptoms predicted negative biases in their reports of their child's ADHD symptoms, general behavior problems, and their own negative parenting style. Whereas levels of depressive symptoms did not predict observed parenting behaviors, maternal distortions did predict problematic parent–child interactions. Exploratory analyses showed a marginally significant mediation effect of the relationship between maternal depressive symptomatology and reports of negative parenting by depressive distortions. We discuss implications of linkages between depressive symptoms in mothers, depression-related distortions, and mother–child relationships for research and intervention in developmental psychopathology.

Mothers' affect dysregulation,depressive symptoms,and emotional availability during mother–infant interaction

Maternal affect dysregulation and maternal depressive symptoms were examined as predictors of maternal emotional availability (EA) during mother–infant interaction in a nonclinical sample. In particular, we investigated if affect dysregulation predicts EA and is more important than are depressive symptoms in predicting EA. Questionnaire measures and 30 min of free play were obtained from 46 mothers of 4‐ to 5‐month‐old infants. Mothers' self‐reported affect dysregulation was inversely related to EA, but mothers' depressive symptoms were not related to EA. More specifically, mothers' tendency to use unhealthy externalizing behaviors to reduce tension and distress predicted less EA. These results suggested that even in relatively low‐risk samples, mothers' self‐reported affect dysregulation, particularly the tendency to act out inappropriately in response to tension and distress, may be a more proximal predictor of EA than are depressive symptoms.     

The depressive personality disorder inventory and current depressive symptoms: implications for the assessment of depressive personality

The Depressive Personality Disorder Inventory (DPDI; Huprich, Margrett, Barthelemy, & Fine, 1996; see Appendix) was created to assess Depressive Personality Disorder in clinical and nonclinical samples. Since its creation, the DPDI has been used in multiple studies, and the psychometric properties of the measure have generally supported its reliability, convergent validity, and construct validity; however, evidence for the measure's discriminant validity has been mixed. Specifically, the DPDI tends to correlate highly with measures of current depressive symptoms, which limits its efficacy in differentiating current depressive symptoms from a depressive personality structure. A principal components analysis of 362 individuals who completed both the DPDI and Beck Depression Inventory (BDI-II; Beck, Steer, & Brown, 1996) found that 49% of the variance was accounted for in two components. Seven items from the DPDI loaded more strongly on the first component composed of many BDI-II items. These items were removed in order to create a measure believed to assess DPD without the confounding influence of current depressive symptomology. Principal components analysis of the revised measure yielded three components, accounting for 46% of the variance. The revised DPDI was used to calculate convergent, discriminant, and construct validity coefficients from measures used in former studies. Virtually no improvement in the validity coefficients was observed. It is concluded that assessing DPD via self-report is limited in its utility.
