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

A cluster analysis of attachment styles in patients with borderline personality disorder, bipolar disorder and ADHD

BACKGROUND

Insecure adult attachment has been associated with psychiatric disorders characterized by emotional dysregulation, such as borderline personality disorder (BPD), bipolar disorder (BD) and attention deficit/hyperactivity disorder (ADHD). However, little is known about the differences in attachment patterns between these diagnostic groups. The aim of this study was to identify clusters of adult attachment style in a cross-diagnostic group of patients with BDP and/or BD and/or ADHD and explore the characteristics of these clusters based on temperament profile, childhood trauma and psychiatric diagnoses.

METHODS

K-means cluster analysis was used to identify subgroups, based on the Attachment Style Questionnaire Short Form dimensions, in a clinical cohort of 150 young adults (113 women and 37 men, mean age ± SD = 23.3 ± 2.1) diagnosed with BPD, and/or BD, and/or ADHD.

RESULTS

Three distinct clusters were identified: a secure, an insecure/avoidant-anxious and an insecure/avoidant cluster. These three clusters differed in temperament profile and related psychiatric diagnoses.

CONCLUSIONS

The three clusters of attachment in individuals with BPD, BD and/or ADHD could support differentiation between the disorders as well provide information usable for planning of treatment.

Beyond Symptoms - A Cross-Sectional Study Exploring Functioning in Psychiatric Outpatients

OBJECTIVE

This study aimed to explore factors influencing functioning in psychiatric outpatients, both separately and in combination. The primary objectives were to determine predictors of functioning, assess their significance in a combined analysis, and quantify their collective predictive power.

METHOD

A sample of 137 psychiatric outpatients diagnosed with bipolar disorder, borderline personality disorder, or attention deficit hyperactivity disorder (ADHD) participated in this cross-sectional study, undergoing semi-structured diagnostic interviews for psychiatric and personality disorders. Participants also completed assessments of current functioning, personality traits (temperament and character), attachment style, and childhood trauma. Linear regression models were employed to analyse the relationships between these factors and level of functioning.

RESULTS

The majority of temperament and character traits and attachment dimensions, as well as having a personality disorder, predicted impaired functioning, but comorbidity and childhood trauma did not. When all variables were taken into account in a multiple regression analysis, only the temperament and character traits Harm Avoidance and Self-directedness remained significantly predictive (p = .006 and .003, respectively). These two factors explain about one-third of the variance.

CONCLUSIONS

Personality traits-more specifically, the temperament trait Harm Avoidance and the character trait Self-directedness-are strong predictors of functioning among psychiatric outpatients. Interestingly, when accounting for these factors, traditionally associated variables, such as attachment, comorbidity, and childhood trauma, lost their significance as predictors. These findings underscore the pivotal role of specific personality traits in understanding and predicting the functioning of psychiatric patients.

Validation of Self-Reported Attachment Classification Among Racially and Ethnically Diverse Parents of Young Children

BACKGROUND

The Attachment Style Questionnaire (ASQ) was developed to measure individual differences in insecure adult attachment and was suitable for populations that may have minimal or no experience in romantic relationships. The measure was previously validated on homogenous populations.

OBJECTIVES

The purpose of this study was to verify construct validity and internal consistency of the ASQ among an ethnically and racially diverse sample of caregivers of young children ages birth to 3 years.

METHODS

Using a cross-sectional design, we examined the psychometric properties of the ASQ. A racially and ethnically diverse sample of caregivers of young children (birth to 3 years old) completed the 40-item measure. Factor analyses and internal consistency analyses were conducted.

RESULTS

Confirmatory factor analyses showed that the previously published factor structures were not a good fit for this diverse sample. Exploratory factor analysis with promax rotation revealed a four-factor solution among 16 items, including relationship anxiety, relationships as secondary, discomfort with closeness, and relationship distrust. Adequate internal consistency was noted for the factors, and structural invariance was confirmed across Hispanic and non-Hispanic ethnicities.

DISCUSSION

Nurse scientists and practitioners should take caution when using or developing indices based on previous research. There should be consideration of structural stability and replication across the intended population.

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 Interplay of Attachment Styles and Defense Mechanisms on Eating Disorders Risk: Cross-Sectional Observation in the Community Population

OBJECTIVE

Eating Disorders (Eds) are considered a broad group of pathological conditions characterized by dysregulated eating-related behaviors and habits. Attachment styles and defense mechanisms appear to be linked to the development of EDs-related unhealthy behaviors; however, these factors have been seldom investigated jointly. This study aimed at exploring the shared association between attachment styles, defense mechanisms, and EDs-related behaviors; additionally, we aimed at investigating whether defense mechanisms might be potential mediators of the association between attachment and Eds behaviors.

METHOD

A community-based sample was recruited (88% females, mean age= 22.33 ± 4.81 years) and underwent a comprehensive evaluation protocol assessing attachment styles, defense mechanisms, and risk of eating disorders.

RESULTS

Several shared associations between attachment styles, defense mechanisms, and eating disorders scores were found. Additionally, a maladaptive defense style appeared to be a significant mediator of the association between attachment styles and EDs-related symptoms.

CONCLUSIONS

The integrated evaluation of attachment and defense mechanisms could generate a more comprehensive framework of the psychological antecedents related to Eating Disorders, and it could be a beneficial factor involved in therapies.

Radically open dialectical behaviour therapy adapted for adolescents: a case series

BACKGROUND

Overcontrol is a transdiagnostic cluster of traits associated with excessive psychological, behavioural and social inhibitory control. It is associated with psychiatric diagnoses of depression, restrictive eating disorders and/or obsessive-compulsive personality disorder. Radically Open Dialectical Behaviour Therapy is a transdiagnostic treatment for maladaptive overcontrol. This case series evaluates an adolescent adaption (RO-A) for a transdiagnostic group of adolescents identified as overcontrolled.

METHODS

Twenty-eight adolescents were consecutively referred for RO-A from two different National and Specialist Child and Adolescent Mental Health Services between June 2017 and February 2020. Baseline self-report measures assessed overcontrol characteristics, relationship and attachment quality and mental health symptoms of depression and eating disorders, which were repeated at discharge.

RESULTS

Adolescents in this case series reported high rates of depression (78.6%), self-harm (64.3%) and eating disorders (78.6%). Most (85.7%) had two or more mental health diagnoses and all had previous mental health treatments before starting RO-A. The mean number of RO-A sessions attended was 18 group-based skills classes and 21 individual sessions over a mean period of 34 weeks. Significant improvements with medium and large effect sizes were reported in cognitive flexibility (d = 1.63), risk aversion (d = 1.17), increased reward processing (d = .79) and reduced suppression of emotional expression (d = .72). Adolescents also reported feeling less socially withdrawn (d = .97), more connected to others (d = 1.03), as well as more confident (d = 1.10) and comfortable (d = .85) in attachment relationships. Symptoms of depression (d = .71), eating disorders (d = 1.06) and rates of self-harm (V = .39) also significantly improved. Exploratory correlation analyses suggest improvements in overcontrol are moderately to strongly correlated with improvements in symptoms of depression and eating disorders.

CONCLUSIONS

This case series provides preliminary data that RO-A may be an effective new treatment for adolescents with overcontrol and moderate to severe mental health disorders like depression and eating disorders. RO-A led to improved management of overcontrol, improved relationship quality and reduced mental health symptoms. Further evaluation is indicated by this case series, particularly for underweight young people with eating disorders. More rigorous testing of the model is required as conclusions are only tentative due to the small sample size and methodological limitations.

Exploration of the Spanish Version of the Attachment Style Questionnaire: A Comparative Study between Spanish, Italian, and Japanese Culture

Nowadays, there are several human attachment measures, most in the form of questionnaires that assess adult attachment styles. This study investigates the use of Feeney, Noller, Hanrahan, Sperling and Berman’s five-factors Attachment Style Questionnaire (ASQ, 1994), based on Bartholomew’s four-factors model (1991), and Hazan and Shaver’s three-factors model (1987). Nevertheless, no robust study has explored the ASQ questionnaire in Spanish compared to other cultures, such as Italian and Japanese. Therefore, the linguistic translation of the Spanish version of the ASQ was performed, based on the back-translation methodology. The results indicate that 5-factors ASQ Spanish version explains 43.67% of the variance, similar to the original English-Australian ASQ version. The Italian and Japanese versions explain 49.37% and 52.27% of the variance, respectively. No age correlation for any ASQ factors in the Japanese sample was found; meanwhile, the Spanish and Italian cultures showed a positive correlation with age and “Confidence” and negative correlation with age and “Relationships as Secondary” ASQ factors. Some transcultural differences and possible research approaches are addressed.

Targeting maladaptive overcontrol with radically open dialectical behaviour therapy in a day programme for adolescents with restrictive eating disorders: an uncontrolled case series

BACKGROUND

Radically Open Dialectical Behaviour Therapy (RO-DBT) was developed to target maladaptive overcontrol, a proposed core difficulty of restrictive eating disorders. RO-DBT is now the main group treatment model at the Intensive day Treatment Programme (ITP), Maudsley Hospital. This ITP case series aimed to investigate whether overcontrol is associated with restrictive eating disorder symptoms in adolescents and to evaluate ITP outcomes since RO-DBT skills classes were introduced.

METHOD

Self-report measures of eating disorder symptoms and temperament, personality and social characteristics linked to overcontrol were collected at assessment and discharge from ITP for all consecutive adolescents who attended between February 2015 and January 2019 (N = 131). Weight change, global outcomes and treatment needs post-ITP were also recorded.

RESULTS

Eating disorder symptoms at assessment were significantly correlated with overcontrol factors, including social connectedness (r = -.67), reward responsivity (r = -.54), and cognitive inflexibility (r = .52). Adolescents stayed in ITP on average 13.40 weeks. 70.8% had a Good-Intermediate outcome on Morgan-Russell scale. 4.6% did not respond and were referred to inpatient treatment from ITP. Significant improvements in drive for thinness (d = .33), depressive mood (d = .41), social connectedness (d = .48), and emotional expressiveness (d = .97) were reported at discharge. No changes were observed in perfectionism or negative temperament.

CONCLUSIONS

This study offers preliminary evidence that eating disorder symptoms are associated with overcontrol factors in adolescence and that they can improve with RO-DBT informed day programme treatment. RO-DBT is a promising treatment that offers a new way of conceptualising treatment targets and recovery for adolescent restrictive eating disorders.

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.

Links between an Owner's Adult Attachment Style and the Support-Seeking Behavior of Their Dog

The aim of this study was to investigate if an owner's adult attachment style (AAS) influences how their dog interacts and obtains support from them during challenging events. A person's AAS describes how they perceive their relationship to other people, but it may also reflect their caregiving behavior, and so their behavior toward the dog. We measured the AAS of 51 female Golden retriever owners, using the Adult Attachment Style Questionnaire (ASQ), and observed the reactions of the dog-owner dyads in response to different challenging situations [visual surprise, auditory stressor and social stressors like a person approaching dressed as ghost or in coat, hat and sunglasses]. In addition, the dog was left alone in a novel environment for 3 min. Interactions between the dog and owner were observed both before and after separation. Spearman rank correlation tests were made (between owner AAS and dog behavior) and where correlations were found, Mann-Whitney U-tests were made on the dogs' behavioral response between high and low scoring groups of owners of the different subscales of the ASQ. The more secure the owner (ASQ subscale 'Confidence'), the longer the dog was oriented to the two sudden stressors (the visual and auditory stressor). The more anxious the owner (ASQ subscale 'Attachment anxiety'), the longer the dog oriented toward the owner during the approach of the strange-looking person and the dog showed less lip licking during separation from the owner. The more avoidant the owner (ASQ subscale 'Avoidant attachment'), the longer the dog oriented toward the owner during the visual stressor, the less it was located behind the owner during the auditory stressor and the less it was oriented toward the auditory stressor. These links between owner attachment style and dog behavior imply that dogs may develop different strategies to handle challenging situations, based on the type of support they get from their owner.

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.
