Abstract Maternal depression poses a risk for the developing mother-infant relationship. Similarly, maternal insecure attachment styles may limit the ability to adequately
connect with the newborn during the postpartum period.
The aim of this study was to investigate the effect of
maternal depression and insecure attachment (insecure
and dual/disorganized) on maternal bonding in a sample
of n = 34 women with depression according to DSM-IV
and n = 59 healthy women. Maternal depression was
assessed 3 to 4 months postpartum with the Structured
Clinical Interview for DSM-IV Axis I Disorders (SCIDI), bonding with the Postpartum Bonding Questionnaire,
and maternal attachment style with the Attachment Style
Interview. Women with current and lifetime depression as
well as women with dual/disorganized attachment style
reported lower bonding. Explorative analysis revealed that
d ep r es s i on p ar t i al l y m e d i a t e d t he l i n k be t w e e n
dual/disorganized attachment style and bonding with a
medium-sized mediation effect. The combination of maternal depression and dual/disorganized attachment style
may pose a special risk constellation for the developing
mother–infant bond that should be addressed in prevention and early intervention programs.

Bonding . Mother–child relationship
Introduction
The postpartum period is a challenging time for mothers as the
care for an infant requires constant attention to the infant’s
needs. Bonding, described as the emotional tie of a mother
to her newborn (Klaus et al. 1995) that develops gradually
after birth, ensures protection and nurture of the newborn
and is highly relevant for the establishing mother–infant relationship (Brockington 2004; Klaus and Kennell 1982).
Expressions of bonding in maternal postpartum behavior include proximity seeking, touch, contact, gaze, baby talk, positive expression, cuddling, smiling, and adaptation to cues
expressed by the infant (Reck et al. 2006). On the other hand,
bonding is associated with cognitive-emotional variables, including positive feelings, emotional warmth, and affection
(Klaus et al. 1995). In animal studies, this maternal behavior
was related to diverse positive effects for the offspring, such as
a longer period of brain development, engendering diverse
morphology and physiology of the brain, more adaptive stress
reactivity, and higher levels of social affiliation (Meaney
2001). Studies in humans resulted in similar findings. For
example, adverse parental bonding was associated with higher
autonomic stress response to distress stimuli in children
(Dalsant et al. 2015). Furthermore, bonding is influenced by
situational factors as well as by personality variables of the
mother. A powerful situational predictor is maternal mental
health. There is robust evidence that the probability for impaired bonding is higher in women suffering from depression
(Dubber et al. 2015; Moehler et al. 2006; Reck et al. 2006;
Tietz et al. 2014). Here, not only current maternal
928
psychopathology but also remitted and lifetime diagnoses
have long-term influences on maternal variables such as
self-confidence concerning the maternal role (Reck et al.
2012) and parenting behavior (Thomas et al. 2015).
Bonding capacities are also related to developmentally
shaped relationship expectancies, as for example described
by attachment theory. Mental representations of early and repeated interactions with caregivers (Bowlby 1977) influence
adult attachment. These representations are organized in
Binternal working models^ and comprise expectations and
beliefs about the self and attachment figures (Bowlby 1982),
which are then internalized and generalized over the course of
development. These internal working models are relatively
stable across the lifespan (Grossmann and Grossmann 1991)
and influence attitudes towards closeness, attachment behavior, quality of romantic relationships, and social support in
adulthood (Bowlby 1977; Grossmann and Grossmann 2004;
Main et al. 1985). Even more relevant for our study, attachment representations affect the way caregivers interact with
and feel about their children (Bowlby 1982). While self-report
questionnaires mainly assess attachment with regard to two
continuous dimensions of insecurity—anxiety and avoidance
(where anxious individuals are characterized as ambivalent,
desiring proximity but concurrently fearing rejection and
avoidant individuals as seeking independence and autonomy,
e.g., Paetzold et al. 2015)—a particular strength of related
interview measures is that they provide further information
about disintegrated or contradictory internal working models
of attachment. Focusing on adult representations of own childhood experiences with the family of origin, the Adult
Attachment Interview (George et al. 1985; Main et al. 1985)
provides a classification corresponding to child’s disorganization labeled Bunresolved^ for individuals with an unresolved
state of mind and disorientation or disorganization when
discussing potentially traumatic events, such as loss or abuse
(Main and Goldwyn 1984). Due to the evaluation of narrative
coherence, the AAI is particularly distinct from other attachment measures when assessing unconscious aspects of attachment and internal representation of primary caregivers, as well
as unresolved states of minds. When investigating other aspects of attachment, as for example current relationships or
contradictory behaviors and affects in adulthood, it might be
suitable to make use of other attachment measures. The
Attachment Style Interview (ASI) (Bifulco et al. 2002) is
one kind of interview which focuses on attachment in current
adult relationships, with regard to the quality of close, supportive relationships with the partner (if present) and other
close confidants, and was therefore used in this study. We
assume that the way a person feels about current close relationships to other adults might also reflect the way the relationship to the baby is formed and experienced. Like the AAI,
the ASI also describes an attachment strategy which is incoherent with regard to associated behavioral aspects, such as
N. Nonnenmacher et al.
contradictory patterns of approach and avoidance or fear and
anger of others. As it constitutes a combination of anxious and
avoidant attachment styles, this category is labeled dual/disorganized. Dual/disorganized attachment is directly associated
to psychopathology (Schimmenti and Bifulco 2008), interpersonal problems in adolescence (Schimmenti and Bifulco
2008), and discomfort in romantic relationships in adulthood
(Paetzold et al. 2015) but also to maladaptive parenting
(Busch et al. 2008; Goldberg et al. 2003). So far, organized
insecure attachment strategies were closely linked to depression per se, its duration and severity (Conradi and de Jonge
2009; McMahon et al. 2008), and the occurrence of postpartum depression (Bifulco et al. 2004; Ikeda et al. 2014).
Moreover, an association of insecure adult attachment with
lower quality of relationship to the baby (Rholes et al. 1995;
Wilkinson and Mulcahy 2010) and less adequate parenting
behavior (Bifulco et al. 2009; Haltigan et al. 2014) was reported. The role of dual/disorganized attachment for the maternal
subjective relationship to the baby has not yet been
examined.
In sum, bonding, maternal depression, and maternal adult
attachment style are all related, but the exact relationship between the three variables remains unclear. To the best of the
authors’ knowledge, this is the first study to investigate the
role of maternal depression and attachment style for the subjective bonding relationship mothers develop towards their
newborn. In line with previous studies, we assume that
mothers with depression report lower bonding than nondepressed mothers. Furthermore, we assume that depressed
women show an insecure or dual/disorganized attachment
style more often. Due to the link between adult attachment
and quality of close relationships, we hypothesize that maternal insecure or dual/disorganized attachment style negatively
influences the way a mother feels about the relationship to her
child, operationalized via self-reported maternal bonding. As
dual/disorganized attachment differs from insecure attachment
in the inconsistency of attachment strategy and maladaptive
overall functioning, we focused on this attachment style in
explorative analyses. More specifically, we were interested if
maternal depression mediates the expected relationship between dual/disorganized attachment style and bonding.
Method
Procedure and participants
Participating mothers (N = 107) gave birth between May 2009
and December 2012 and were recruited in local maternity
hospitals (n = 104) and the mother–infant unit (n = 3) of the
Department of General Psychiatry, Heidelberg University
Hospital. Eligible mothers were screened for depressive syndromes according to DSM-IV and subsequently interviewed
Postpartum bonding: maternal depression and adult attachment
with the Structured Clinical Interview for DSM-IV Axis I
Disorders (SCID-I) (Wittchen et al. 1997) within the first
3 m o n t h s p o s t p a r t u m . T h e P o s tp a r t u m B o n d i n g
Questionnaire-16 (PBQ-16) (German version, Reck et al.
2006) and the ASI (Bifulco et al. 2002) were completed at
an assessment point 3 to 4 months postpartum. The interviews
were videotaped and subsequently rated by trained psychologists or master students, which were blind to the mental health
status of the mothers.
The initial sample size of N = 107 mothers was reduced to
n = 93 mothers due to missing interviews (n = 3) and the exclusion of women without depression but with other psychiatric diagnoses (n = 11). According to their mental health status, mothers were assigned to the healthy (n = 59) or depressed
(n = 34) group. The healthy group consisted of mothers without current or lifetime psychiatric disorders or psychotherapeutic experience. Mothers in the depressed group suffered
from major (n = 29) or minor (n = 5) depression with 35.3 %
comorbid anxiety disorders (n = 12), 14.7 % eating disorders
(n = 5), and 5.9 % posttraumatic stress disorders (n = 2). A
total of n = 15 mothers (44.1 %) were in an acute depressive
episode, whereas n = 19 mothers (55.9 %) had a lifetime diagnosis of depression. All participating mothers needed to be
at least 18 years old and have adequate knowledge of the
German language. The study protocol was approved by the
Ethics Committee of the Medical Faculty, Heidelberg
University Hospital. Written informed consent was obtained
after the study procedures had been fully explained.
Sample characteristics
Maternal age ranged from 24 to 44 years with a mean of
M = 33.95 years (SD = 4.52) within the overall sample
(n = 93). On average, women had M = 1.53 children
(SD = 0.58) ranging from 1 to 4.
Infant’s age ranged from 12.7 to 17.9 weeks with a
mean age of M = 14.59 (SD = 1.41) weeks. With regard
to the total sample, n = 49 (52.7 %) children were female
and n = 44 (47.3 %) were male. The distribution of maternal education level in the overall sample was as follows:
n = 22 (23.7 %) completed intermediate secondary education, n = 12 (12.9 %) qualified for university admission,
and n = 59 (63.4 %) held a university degree. Detailed
sociodemographic information can be found in Table 1.
Measures
Structured Clinical Interview for DSM-IV Axis I Disorders
(SCID-I)
Maternal mental health was assessed with the German version of the SCID-I (Wittchen et al. 1997) by trained, experienced psychologists. The SCID-I is a widely used
929
semistructured interview for the diagnosis of selected axis
I disorders. The authors of the German version evaluated
the psychometric properties regarding reliability, applicability, and efficacy as satisfying.
Postpartum Bonding Questionnaire-16 (PBQ-16)
The PBQ was originally developed as a self-report measure
for the screening of bonding disorders (Brockington et al.
2001). We used the abridged 16-item German version (PBQ16, Reck et al. 2006). Items such as BI feel close to my baby^
or BMy baby irritates me^ are rated on a 6-point Likert scale
from 0 (Bnever^) to 5 (Balways^). High values on the PBQ-16
indicate lower levels of bonding. In our sample, internal consistency was good (Cronbach’s α = 0.89), and the sum scores
ranged between 0 and 40 (M = 9.16, SD = 7.94).
Attachment Style Interview (ASI)
This semistructured interview (Bifulco et al. 2002) focuses on
current behavior and attitudes to assess adult attachment, including secure, anxious (enmeshed or fearful), and avoidant
(angry-dismissive or withdrawn) attachment styles. In the
first part of the interview, participants describe the quality
of their close, supportive relationship with the partner (if
present) and other close confidants. Scales assessed are
Bconfiding, active emotional support, positive and negative
interaction, and felt attachment^ for each of the three support
figures. The quality of each relationship can be coded and
added to an overall Bability to make and maintain
relationships.^ The second part of the interview assesses personal attitudes regarding attachment and can be assigned to
either an anxious (e.g., fear of separation, desire for company,
anger) or avoidant type (e.g., mistrust, constraints on closeness, high self-reliance, fear of rejection). The ratings on
these scales are used to categorize the type of attachment style
(secure, high on anxiety: enmeshed, fearful or high on avoidance: angry-dismissive, withdrawn) and the degree of insecurity (markedly, moderately, or mildly insecure). Dual/
disorganized attachment style is characterized by a Bdouble^
classification of style, occurring when no clear attachment
pattern can be recognized. In this case, two insecure attachment styles were evident across relationships (Bifulco et al.
2002). This attachment style is described to be contradictory
in the approach and avoidance of others as well as in fear and
anger to others (Bifulco and Thomas 2012). Furthermore, this
classification is associated to traumatic experiences
(Schimmenti and Bifulco 2008). In order to assure the quality
of the ratings, n = 14 (14 %) randomly selected tapes were
double coded by two independent study coders. Interrater
reliability was computed using Cohen’s k (Cohen 1960) and
was k = 0.82 for the double coded tapes.

Statistical analyses
We used the Statistical Package for Social Sciences
(IBMTM SPSS® v. 22) for all analyses. Maternal attachment was operationalized by the use of a variable with
three levels: securely attached, insecurely attached (anxious and avoidant styles), and dual/disorganized attachment style. Due to small subsample sizes, women with
anxious and avoidant insecure attachment styles were allocated to the category Binsecure attachment.^ To ensure
comparability between the depressed and healthy group,
differences concerning maternal age, child age, number
of children, maternal education, and infant gender were
explored (using t tests and χ2 tests) before carrying out
the main analyses (see Table 1).
For further determination of specific characteristics of
maternal depression and to include possible situational influences on maternal bonding capacity, we operationalized
a new variable called Bmaternal depression^ with regard to
three levels of severity: without history of SCID-I diagnoses (never), lifetime diagnoses (lifetime) of depression, and
current diagnoses during the postpartum period (current).
The assumption that maternal depression is rank scaled
regarding the impact on the mother–child relationship is
supported by recent findings, demonstrating that maternal
bonding was differently affected by the course of depression: While the lowest bonding was reported during an
acute episode, it significantly increased when symptoms
of depression remitted but still differed significantly from
the reported bonding of healthy mothers (Reck et al. 2015).
Subsequently, we used Kruskal-Wallis test to analyze
the distribution of maternal depression concerning
P
0.40b
0.47b
attachment style. Two Mann-Whitney U tests were performed as post hoc tests to examine subgroup differences
of maternal depression.
Assumed differences between the depressed and healthy
group in their reported bonding were tested by ANOVA
with three levels (never, lifetime, current). Tukey post
hoc tests were computed to analyze subgroup differences
of maternal depression (never, lifetime, current). A second
ANOVA analyzed the influence of maternal attachment
style (secure, insecure, dual/disorganized) on reported
bonding. Tukey post hoc tests were computed to test for
subgroup differences of maternal attachment style.
In explorative analyses, maternal depression was
tested as a mediator of the relationship between
dual/disorganized attachment style (independent variable) and bonding (outcome variable). We carried out
the standard procedure according to Preacher and
Hayes (2004) using the SPSS®-Macro BPROCESS^
(v. 2.15) (Hayes 2013). The model estimates the direct
effect of maternal dual/disorganized attachment style
on maternal depression, the indirect effect of maternal
dual/disorganized attachment style on bonding mediated by maternal depression as well as the direct effect
of maternal dual/disorganized attachment style on
bonding (see Fig. 1). The standard errors and confidence intervals of the indirect (mediated) effects are
bootstrapped and bias-corrected (N = 1000 samples).
Empirical p values are two-tailed.
Before carrying out the mediation analysis, Pearson’s
correlations were conducted to screen for associations
between dual/disorganized attachment style, maternal
depression, and bonding.
