Maternal attachment insecurity is a potent predictor of depressive symptoms in the early postnatal period

Risk psychosocial factors associated with postpartum depression trajectories from birth to six months

PURPOSE

The purpose of this study was to assess the trajectory of women's depressive symptoms during the first six months postpartum, identify risk factors (sociodemographic, obstetric and personality) associated with classes, and examine associations between classes and postpartum PTSD at two months and bonding at six months.

METHODS

The final sample included 212 women who gave birth in the maternity wards of a large tertiary health center that were approached at 1-3 days, two months, and six months postpartum and completed a demographic questionnaire and measures of neuroticism (BFI) and postpartum depression (EPDS), postpartum PTSD (City Birth Trauma Scale) and bonding (PBQ). Obstetric data were taken from the medical files.

RESULTS

Cluster analysis revealed three distinctive clusters: "stable-low" (64.2%), "transient-decreasing" (25.9%), and "stable-high" (9.9%). Neuroticism, general-related PTSD symptoms, and bonding were associated with differences between all trajectories. Birth-related PTSD symptoms were associated with differences between both stable-high and transient-decreasing trajectories and the stable-low trajectory. No obstetric or demographic variables were associated with differences between trajectories.

CONCLUSION

We suggest that screening women for vulnerabilities such as high levels of neuroticism and offering treatment can alleviate the possible deleterious effects of high-symptom depression trajectories that may be associated with their vulnerability.

Attachment classification and early adversity predict perinatal partial hospital treatment response

BACKGROUND

Depression and anxiety are common in the perinatal period. While most of those affected respond well to treatment, a subpopulation is more resistant. Understanding more about individuals who do not respond well to available treatments may improve care for this group.

METHODS

We administered entry and exit self-report measures to 178 women who participated in a specialized partial hospitalization program for perinatal individuals. Baseline measures of anxiety, obsessive symptoms, sleep quality, early life adversity, and adult attachment security were examined as potential predictors of response to treatment.

RESULTS

While no individual baseline survey predicted treatment response, clustering patients on the basis of a combination of self-report adult attachment styles and early life adversity yielded four distinct groups. A cluster with high attachment anxiety, high attachment avoidance, and childhood history of verbal and emotional abuse was less responsive to treatment than the other groups.

CONCLUSIONS

Combining detailed information about self-report adult attachment style and early life adversity may improve prediction of treatment response in individuals with perinatal mood and anxiety disorders.

Anxiety and depressive symptoms in first-time parents: A dyadic longitudinal study based on attachment theory

BACKGROUND

The aim of this study was to examine the temporal and dyadic associations between anxiety and depressive symptoms during the transition to parenthood (TTP), while exploring the antecedence of attachment insecurities in these associations.

METHOD

Couples of first-time parents (N = 211) completed the State-Trait Anxiety Inventory, the Edinburgh Postnatal Depression Scale, the Experiences in Close Relationships scale, and a sociodemographic questionnaire during the second trimester of pregnancy and at four and twelve months postpartum.

RESULTS

Both prenatal anxiety and depressive symptoms predicted postnatal depressive and anxiety symptoms. Prenatal attachment-related anxiety predicted higher postnatal anxiety and depressive symptoms whereas prenatal attachment-related avoidance predicted higher postnatal depressive symptoms only. Parents whose partners had a higher level of prenatal attachment-related anxiety experienced higher postnatal anxious and depressive symptoms via their own's prenatal depressive symptoms. Parents whose partners had a higher level of prenatal attachment-related avoidance experienced higher postnatal depressive symptoms via their own's prenatal anxious symptoms. No gender differences were found for these associations.

LIMITATIONS

The sample was predominantly composed of educated heterosexual French-Canadian Caucasian couples and all measures were self-reported.

CONCLUSIONS

Our original findings suggest that professionals should routinely screen for anxiety and depressive symptoms in both partners from pregnancy up to one year postpartum. Also, our findings suggest addressing attachment insecurities with both partners to prevent the development of future symptoms during pregnancy or after childbirth. Finally, our study supports the relevance of considering these symptoms at subclinical levels during the TTP.

COVID-19-Related worries mediate the association between attachment orientation and elevated depression levels at 21-month postpartum

BACKGROUND

The study's aims were to examine whether the COVID-19 pandemic was associated with increases in depression levels of 21 months postpartum women who were initially sampled before the pandemic and whether COVID-19-related worries mediated the association between women's attachment orientations and this hypothesized increase.

METHODS

Participants comprised 185 postpartum women sampled in the maternity ward of a tertiary healthcare center in Israel followed from childbirth to 21 months postpartum in four-time points. . We analyzed demographic and obstetric information and the Experiences in Close Relationships (ECR) scale at T1; changes in the Edinburgh Postnatal Depression Scale (EPDS) levels at all timepoints (T1-4); and COVID-19-related worries at T4.

RESULTS

Results showed a significant increase in depression levels at T4 compared to T2 and T3, and an increase in the prevalence of women at the lower clinical EPDS threshold. COVID-19-related worries mediated the association between anxious attachment and depression (indirect effect: B = .21, p < .05, 95% CI = (.015, .47), R2=0.12).

DISCUSSION

The evident effect of COVID-19 on postpartum depression is associated with variability between people. Thus, early assessment of women's attachment orientations might provide a strategy for identifying and treating women at risk.

Psychological Characteristics of Women with Perinatal Depression Who Require Psychiatric Support during Pregnancy or Postpartum: A Cross-Sectional Study

Antenatal depression may be distinct from postpartum depression in terms of prevalence, severity of symptoms, comorbidities, prognosis, and risk factors. Although risk factors for perinatal depression have been identified, it is unclear whether there are differences in the onset of perinatal depression (PND). This study explored the characteristics of women requiring mental health support during pregnancy or postpartum. A sample of 170 women (58% in pregnancy; 42% postpartum) who contacted the SOS-MAMMA outpatient clinic was recruited. Clinical data sheets and self-report questionnaires (EPDS, LTE-Q, BIG FIVE; ECR; BSQ; STICSA) were administered, hypothesizing possible risk factors, such as personality traits, stressful life events, body dissatisfaction, attachment style, and anxiety. Hierarchical regression models were carried out in the pregnancy (F_10;36 = 8.075, p < 0.001, adjR2 = 0.877) and postpartum groups (F_10;38 = 3.082, p < 0.05, adjR2 = 0.809). Recent stressful life events and conscientiousness were associated with depression in both the pregnant (29.3%, 25.5% of variance) and postpartum groups (23.8%, 20.7% of variance). In pregnant women, "openness" (11.6%), body dissatisfaction (10.2%), and anxiety (7.1%) symptoms were predictive of depression. In the postpartum group, "neuroticism" (13.8%) and insecure romantic attachment dimensions (13.4%; 9.2%) were the strongest predictors. Perinatal psychological interventions should consider the differences between mothers with depression during pregnancy and postpartum.

Maternal attachment insecurity, maltreatment history, and depressive symptoms are associated with broad DNA methylation signatures in infants

The early environment, including maternal characteristics, provides many cues to young organisms that shape their long-term physical and mental health. Identifying the earliest molecular events that precede observable developmental outcomes could help identify children in need of support prior to the onset of physical and mental health difficulties. In this study, we examined whether mothers' attachment insecurity, maltreatment history, and depressive symptoms were associated with alterations in DNA methylation patterns in their infants, and whether these correlates in the infant epigenome were associated with socioemotional and behavioral functioning in toddlerhood. We recruited 156 women oversampled for histories of depression, who completed psychiatric interviews and depression screening during pregnancy, then provided follow-up behavioral data on their children at 18 months. Buccal cell DNA was obtained from 32 of their infants for a large-scale analysis of methylation patterns across 5 × 106 individual CpG dinucleotides, using clustering-based significance criteria to control for multiple comparisons. We found that tens of thousands of individual infant CpGs were alternatively methylated in association with maternal attachment insecurity, maltreatment in childhood, and antenatal and postpartum depressive symptoms, including genes implicated in developmental patterning, cell-cell communication, hormonal regulation, immune function/inflammatory response, and neurotransmission. Density of DNA methylation at selected genes from the result set was also significantly associated with toddler socioemotional and behavioral problems. This is the first report to identify novel regions of the human infant genome at which DNA methylation patterns are associated longitudinally both with maternal characteristics and with offspring socioemotional and behavioral problems in toddlerhood.

The associations between insecure attachment, rooming-in, and postpartum depression: A 2 months' longitudinal study

Postpartum depression (PPD) is the most common complication of childbearing, and recent studies have attempted to examine risk factors associated with it. The main study hypothesis was that a protective situational factor at a sensitive time period (full rooming-in postpartum) would moderate the associations between insecure attachment dimensions and PPD. Three hundred twelve women, in either full or partial rooming-in, participated in a longitudinal study at the maternity ward of a tertiary healthcare center. A Demographic questionnaire and the Experiences in Close Relationships Scale were administered at 1-4 days postpartum, and the Edinburgh Postnatal Depression scale at 2 months postpartum. PPD was significantly associated with both anxious and avoidant attachment dimensions, but not with rooming-in conditions. In addition, women in partial rooming-in showed a positive correlation between insecure attachment dimensions and PPD, whereas no such correlation was found for full rooming-in women. A situational factor such as full rooming-in, which occurs at a critical time point for the mother-infant relationship, can moderate the association between maternal avoidant or anxious attachment dimensions and the mother's PPD levels. Postpartum practices, such as rooming-in, can be personalized and thus beneficial in moderating personal risk factors for PPD.

The anxious aspects of insecure attachment styles are associated with depression either in pregnancy or in the postpartum period

BACKGROUND

Perinatal depression (PND) is a major complication of pregnancy and many risk factors have been associated with its development both during pregnancy and postpartum. The transition to motherhood activates the attachment system. The aim of our study was to investigate the relationship between women's attachment style (AS) and PND in pregnancy, and 1 month after childbirth, in a large cohort of women. We hypothesized that different patterns of AS were associated with either antenatal or postnatal depression. We, further, explored the role of other possible risk factors such as life-stress events.

METHODS

A final sample of 572 women was enrolled. At the third trimester of pregnancy, clinical data sheet and self-report questionnaires (ASQ, PSS, LTE-Q, and EPDS) were administered. One month after delivery, EPDS was administered by telephone interview.

RESULTS

We found 10.1% of the women with depression during pregnancy and 11.1% in the postpartum period. The first logistic regression showed that ASQ-CONF subscale (OR = 0.876, p < 0.0001), ASQ-NFA subscale (OR = 1.097, p = 0.002), foreign nationality (OR = 2.29, p = 0.040), low education levels (OR = 0.185, p = 0.012), PSS total score (OR = 1.376, p = 0.010), and recent life adversities (OR = 3.250, p = 0.012) were related to EPDS ≥ 14 during pregnancy.The second logistic regression showed that ASQ-PRE subscale (OR = 1.077, p < 0.001) and foreign nationality (OR = 2.88, p = 0.010) were related to EPDS ≥ 12 in the postpartum period.

CONCLUSIONS

Different dimensions of anxious insecure AS were, respectively, associated with either antenatal or postnatal depression. These findings support the literature investigating subtypes of perinatal depression. The PND may be heterogeneous in nature, and the comprehension of psychopathological trajectories may improve screening, prevention, and treatment of a disorder which has a long-lasting disabling impact on the mental health of mother and child. We provided a rationale for targeting an attachment-based intervention in this group of women.

Epigenetic signatures of attachment insecurity and childhood adversity provide evidence for role transition in the pathogenesis of perinatal depression

Early life adversity and insecure attachment style are known risk factors for perinatal depression. The biological pathways linking these experiences, however, have not yet been elucidated. We hypothesized that overlap in patterns of DNA methylation in association with each of these phenomena could identify genes and pathways of importance. Specifically, we wished to distinguish between allostatic-load and role-transition hypotheses of perinatal depression. We conducted a large-scale analysis of methylation patterns across 5 × 106 individual CG dinucleotides in 54 women participating in a longitudinal prospective study of perinatal depression, using clustering-based criteria for significance to control for multiple comparisons. We identified 1580 regions in which methylation density was associated with childhood adversity, 3 in which methylation density was associated with insecure attachment style, and 6 in which methylation density was associated with perinatal depression. Shorter telomeres were observed in association with childhood trauma but not with perinatal depression or attachment insecurity. A detailed analysis of methylation density in the oxytocin receptor gene revealed similar patterns of DNA methylation in association with perinatal depression and with insecure attachment style, while childhood trauma was associated with a distinct methylation pattern in this gene. Clinically, attachment style was strongly associated with depression only in pregnancy and the early postpartum, whereas the association of childhood adversity with depression was time-invariant. We concluded that the broad DNA methylation signature and reduced telomere length associated with childhood adversity could indicate increased allostatic load across multiple body systems, whereas perinatal depression and attachment insecurity may be narrower phenotypes with more limited DNA methylation signatures outside the CNS, and no apparent association with telomere length or, by extension, allostatic load. In contrast, the finding of matching DNA methylation patterns within the oxytocin receptor gene for perinatal depression and attachment insecurity is consistent with the theory that the perinatal period is a time of activation of existing attachment schemas for the purpose of structuring the mother-child relationship, and that such activation may occur in part through specific patterns of methylation of the oxytocin receptor gene.

Randomized controlled trial of the Circle of Security-Intensive intervention for mothers with postpartum depression: maternal unresolved attachment moderates changes in sensitivity

Postpartum depression is related to inadequately sensitive caregiving, putting infants at risk for insecure attachment. Therefore, promoting sensitive maternal caregiving and secure child attachment is particularly important in postpartum depressed mothers and their infants. In this randomized-controlled-trial, we evaluated the efficacy of the Circle of Security-Intensive (COS-I)-intervention in supporting maternal sensitivity and mother-infant-attachment compared to treatment-as-usual (TAU) with unresolved-maternal attachment as a moderator of treatment effect. Eligible mothers with infants (N=72) 4-9 months-old were randomly assigned to treatment (n=36 dyads). Infant attachment was rated at follow-up (child age 16-18 months) (Strange-Situation-procedure). Maternal sensitivity was measured at baseline and follow-up (Mini-Maternal-Behavior-Q-sort). Maternal-unresolved-attachment was assessed at baseline (Adult-Attachment-Interview). We found no significant differences between treatments in infant attachment nor changes in mothers' sensitivity. However, in COS-I, unresolved-mothers exhibited significantly more change in sensitivity than non-unresolved-mothers, whereas in TAU, the opposite was true. These findings may help to optimize clinical use of COS-I.

Contextual-relationship and stress-related factors of postpartum depression symptoms in nulliparas: a prospective study from Ljubljana, Slovenia

Background

For a significant proportion of women, postpartum depression (PPD) is the first mood episode in their lives, yet its aetiology still remains unclear. Insecure attachment in close adult relationships is considered to be a risk factor for depressive symptoms. This study aimed to gain further insight into the risk factors for postpartum depression symptoms (PPDS) of nulliparas in Slovenia and to examine vulnerability to developing depressive symptoms, with an emphasis on contextual and stress-related characteristics.

Methods

The sample consisted of 156 nulliparas in the third trimester of pregnancy enrolled in a childbirth preparation program. The following instruments were applied: Experiences in Close Relationships-Revised, the Edinburgh Postpartum Depression Scale (EPDS), the Zung Anxiety Scale and a question battery designed by the research team including questions about emotional support and work-related stress. Logistic regression was used to test the association between demographic, social, environmental, personality and attachment variables and PPD of nulliparas (EPDS ≥10), controlling for baseline (prepartum) depression score. A multivariable linear regression model was built with the postpartum EPDS continuous score as a dependent variable.

Results

28/156 (17,9%) were evaluated as being at risk for depression (EPDS≥10) in the last trimester and 25/156 (16%) at six weeks postpartum. The results of the logistic regression model controlled for prepartum depression score showed that increased risk for developing PPDS was associated with anxiety level postpartum, intimate-partner-attachment anxiety postpartum, and elevated stress due to loss of employment or an unsuccessful search for employment in the previous year. The results of the multivariable regression model, however, showed the association with education and postpartum anxiety with PPDS continuous score; EPDS after giving birth was higher for more educated and more anxious primiparas.

Conclusions

Our findings demonstrate the importance of anxiety symptoms and higher education level in assessments of nulliparas’ mental health. The results of our study show and confirm the results of previous research that anxiety symptoms in the immediate postpartum period are likely to be associated with depressive symptoms in nulliparas. The results also suggest that higher level of education of first-time mothers might not be a protective factor, especially for nulliparas with the university level of education. Further studies on larger samples should be considered.

Individual and Contextual Factors of Nulliparas' Levels of Depression, Anxiety and Fear of Childbirth in the Last Trimester of Pregnancy: Intimate Partner Attachment a Key Factor?

BACKGROUND

Depression, anxiety and fear of childbirth have numerous consequences for women and their developing offspring. Insecure attachment in close adult relationships is considered to be a risk factor for depressive symptoms. This study aims to gain further insight into the risk factors for depressive and anxiety symptoms in nulliparous women during the third trimester of pregnancy regarding the main contextual relations, with an emphasis on partner attachment.

METHODS

A group of 325 nulliparas in the third trimester of pregnancy was enrolled in a childbirth preparation program. The following instruments were applied: Experiences in Close Relationships-Revised, the Edinburgh Depression Scale, the Zung Anxiety Scale, and a questionnaire regarding fear of childbirth. Three separate multiple linear regression models were built to explore the associations between demographic, social and attachment variables and mental health functioning.

RESULTS

Highly educated nulliparas and those with a higher level of co-workers' emotional support experienced a lower level of anxiety when other predictors in the model were held constant. Of all the predictors in the model, only attachment anxiety and co-workers' support were statistically significantly associated with the level of depression. Attachment anxiety was significantly associated with all three mental health indicators (level of depression, anxiety and fear of childbirth).

CONCLUSIONS

The results suggest that intimate attachment anxiety could be a key contextual factor for mood and anxiety mental health functioning during the third trimester of pregnancy, accessible to change. Our results could facilitate the formulation of interventions for reducing antenatal depressive symptoms.

Developmental trajectories of attachment and depressive symptoms in children and adolescents

Previous research has found that insecure attachment is associated with depression. In the present study, we use an accelerated longitudinal cohort design to examine how the association between attachment and depression develops during childhood and adolescence. Specifically, 690 children from 3 distinct cohorts (grades 3, 6, and 9) completed self-report measures of attachment and depressive symptoms 3 times over 3 years. Growth curve analyses indicated that attachment anxiety and attachment avoidance were uniquely related to depressive symptoms. Higher levels of attachment anxiety and avoidance predicted higher levels of depressive symptoms over time. Additionally, changes in attachment security were associated with changes in depressive symptoms. The analyses suggest that insecure attachment and depressive symptoms co-vary and that these dynamics are evident in childhood and adolescence.

Depression precedes, but does not follow, gestational diabetes

OBJECTIVES

To determine whether past history of depression is associated with increased rates of gestational diabetes, and whether history of gestational diabetes is associated with increased rates of postpartum depression.

RESEARCH DESIGN

Data for this case-control study consisted of de-identified chart records for 1439 women who received pregnancy care at a large university hospital between 1998 and 2017.

RESULTS

A history of depression prior to pregnancy was associated with gestational diabetes requiring insulin, although not with subtler degrees of gestational hyperglycemia. Diabetes in pregnancy was not associated with an increased risk of postpartum depression. Trauma history was associated with both impaired glucose tolerance in pregnancy and postpartum depression.

CONCLUSIONS

Past episodes of depression increase risk for the most severe form of gestational diabetes; however, gestational diabetes does not contribute significantly to risk for postpartum depression. This suggests a unidirectional association, unlike the bidirectional association of diabetes with depression among the general population. History of trauma increases risk for both gestational hyperglycemia and postpartum depression, suggesting important health effects of trauma that may differ measurably from those associated with depression.

Management of perinatal depression with non-drug interventions

Perinatal depression is a common disorder that has been associated with serious risks to mother and child. Recently, screening for depression in pregnant and postpartum women has increased, as has the development of new psychotherapy and non-drug treatment modalities. Matching patients to treatments can be challenging, and although research into personalized treatment of major depression in the general population has increased, no published guidelines focus on personalized treatment approaches to perinatal depression. In particular, guidelines on non-drug treatments are lacking. This review summarizes the evidence on personalized non-drug treatment of perinatal depression, how to incorporate patients' preferences, novel treatments under investigation, and the potential role of biomarkers in matching patients to treatment. The review provides recommendations for future research in personalized care of perinatal depression.

The role of emotion regulation difficulties in the relationship between attachment representations and depressive and anxiety symptoms in the postpartum period

BACKGROUND

Insecure attachment representations have been established as a vulnerability factor for postpartum depressive symptoms. However, there is a lack of studies on the effects of attachment (in)security on postpartum anxiety symptoms, and on the mechanisms through which attachment representations may affect women's postpartum adjustment, namely, emotion regulation difficulties.

METHODS

The sample included 450 women in the postpartum period (up to 12 months postpartum), who were recruited both online (advertisements on social media) and in person (study was presented by the researchers during the women's postpartum hospitalization).

RESULTS

Approximately one third of the women with clinically significant symptoms (33.3%) presented comorbid symptoms of anxiety and depression, and these women presented more insecure attachment representations and more emotion regulation difficulties (p < .001) than did women without comorbid symptoms (p < .001). The relationship between more insecure attachment representations and depressive and anxiety symptoms occurred both directly and indirectly through emotional regulation difficulties.

LIMITATIONS

The cross-sectional nature of the study, the use of self-report questionnaires that do not allow the establishment of clinical diagnosis and the self-selected bias in recruitment were study limitations.

CONCLUSIONS

The results underline the need for attention to anxiety symptomatology, which is a condition that co-occurs frequently in this period. Interventions that focus on promoting adaptive strategies of emotional regulation are relevant rather than more intensive interventions to change attachment representations.

Maternal programming: Application of a developmental psychopathology perspective

The fetal phase of life has long been recognized as a sensitive period of development. Here we posit that pregnancy represents a simultaneous sensitive period for the adult female with broad and persisting consequences for her health and development, including risk for psychopathology. In this review, we examine the transition to motherhood through the lens of developmental psychopathology. Specifically, we summarize the typical and atypical changes in brain and behavior that characterize the perinatal period. We highlight how the exceptional neuroplasticity exhibited by women during this life phase may account for increased vulnerability for psychopathology. Further, we discuss several modes of signaling that are available to the fetus to affect maternal phenotypes (hormones, motor activity, and gene transfer) and also illustrate how evolutionary perspectives can help explain how and why fetal functions may contribute to maternal psychopathology. The developmental psychopathology perspective has spurred advances in understanding risk and resilience for mental health in many domains. As such, it is surprising that this major epoch in the female life span has yet to benefit fully from similar applications.

Adult attachment's unique contribution in the prediction of postpartum depressive symptoms, beyond personality traits

BACKGROUND

Personality traits such as neuroticism can help identify pregnant women at risk of postpartum depressive symptoms (PPDS). However, it is unclear whether attachment style could have an additional contribution to this risk elevation. This study aimed to examine the overlap of adult attachment insecurity and neuroticism/trait anxiety as PPDS predictors, taking into account baseline depressive symptoms.

METHODS

A Swedish population-based sample of pregnant women reported on adult attachment and either neuroticism (n = 1063) or trait anxiety (n = 555). Depressive symptoms were assessed at baseline, and at six weeks and six months postpartum. Correlations between attachment and neuroticism/trait anxiety were calculated. Generalized linear models of PPDS tested the effect of attachment anxiety and avoidance, adjusting for neuroticism/trait anxiety and baseline depression. Logistic regression models with combined high attachment anxiety and neuroticism/trait anxiety visualized their value as risk factors beyond antenatal depression.

RESULTS

Attachment and neuroticism/trait anxiety were highly correlated (r = .55-.77). Attachment anxiety exerted a partially independent effect on PPDS at six weeks (p < .05) and at six months (p < .05) adjusting for neuroticism. Among antenatally non-depressed, combined high attachment anxiety and high neuroticism or trait anxiety was predictive of PPDS at both assessment points.

LIMITATIONS

Low acceptance rate, exclusive use of self-reports.

CONCLUSIONS

Beyond personality, attachment anxiety had a small independent effect on the risk of PPDS. Combining items of adult attachment and neuroticism/trait anxiety could prove useful in antenatal screening for high risk of PPDS.

Recent advances in understanding maternal perinatal mood disorders

The study of perinatal mental health (mental health during pregnancy and postpartum) is a complex field of study that is of major importance both for the mental and physical health of new mothers and for the neurobehavioral development and long-term functioning of the children they bear. In this review, we cover the most recent additions to this rapidly evolving field. Notable advances include further illumination of the epidemiological patterns and clinical manifestations of perinatal mood disruption; new efficacy data on treatment and prevention; clarifications of the respective contributions of maternal mental illness and psychotropic medication to outcomes of pregnancy, birth, and child development; and updated expert guidelines for screening.

Psychometric properties of the attachment style questionnaire in Swedish pregnant women: short and full versions

OBJECTIVES

(i) To evaluate the reliability and factor structure of the Attachment Style Questionnaire - Short Form (ASQ-SF) for use in pregnant women and (ii) to compare the reliability and factor structure of the short- and full version-ASQ among pregnant women.

BACKGROUND

Adult attachment insecurity is currently included as a major risk factor in studies of perinatal health. None of the self-report measures with a Swedish translation have been psychometrically evaluated in a pregnant cohort.

METHODS

A population-based cohort of 1631 pregnant women answered the ASQ in late pregnancy. Internal consistency (item-subscale correlations, Cronbach's α, and α if item deleted) was evaluated for the seven available subscales. Confirmatory factor analysis (CFA) was run to examine the factor structure of the short form compared with the full-version. Test-retest correlations were assessed in a subgroup (n = 48).

RESULTS

All mean item-subscale correlations for the ASQ-SF were > 0.30. Cronbach's α's for ASQ-SF dimensions were as follows: Avoidance (0.87); Anxiety (0.89); Discomfort with Closeness (0.85); Relationships as Secondary (0.54); Confidence (0.83); Need for Approval (0.76); and Preoccupation with Relationships (0.77). No item removal substantively increased subscale α's. The CFA demonstrated better model fit for the ASQ-SF than for the full-version ASQ, while other reliability measures were similar. Test-retest correlations ranged from 0.65 to 0.84.

CONCLUSION

The ASQ-SF showed similar psychometric properties in pregnant women as in the general population and had good reliability, but the optimal factor structure needs to be studied further. Results support the usage of the ASQ-SF in pregnant cohorts.

Maternal attachment style and psychiatric history as independent predictors of mood symptoms in the immediate postpartum period

BACKGROUND

There is evidence that both a past history of psychiatric illness and insecure attachment put women at risk for mood disturbances in the postpartum period. The aim of this study was to ascertain whether maternal insecure attachment is a risk factor for mood symptoms in the immediate postpartum period independently of the confounding effect of maternal psychiatric history.

METHODS

A convenience sample of 120 mothers was assessed prenatally with the Maternal History of Mood Disturbances (MHMD), the Relationship Questionnaire (RQ), and in the first week after delivery with the Profile of Mood States (POMS).

RESULTS

Mothers with higher scores on the preoccupied and fearful attachment scales had more severe postpartum anxiety and depression symptoms but only fearful attachment remained a significant predictor of postpartum anxiety when the significant effect of maternal history of mood disturbances was included in the model.

LIMITATIONS

Our diagnostic assessment focused on mood symptoms, not disorders, and we limited psychometric assessment to the immediate postpartum period and did not collect longitudinal data to ascertain whether the relationship between maternal insecure attachment and postpartum mood disturbances changed over time.

CONCLUSIONS

Our results show the necessity to assess prior psychiatric symptoms in studies of maternal attachment style and postpartum mood disturbances. The finding that a mother's recall of her own psychiatric history emerged as significant predictor of postpartum mood symptoms suggests that antenatal assessment based on maternal self-report can be used in those settings where structured diagnostic interviews are not feasible.
