Comparative validity of the Adult Attachment Interview and the Adult Attachment Projective

Genetic Contributions on Attachment in Emerging Adults: Cumulative Effects of Serotonergic Polymorphisms

Attachment in emerging adults is closely intertwined with emotion regulation, stress coping, and social bonding during the transition from childhood to early adulthood. Due to the critical roles of serotonin in these mental functions, this research explored whether the cumulative genetic effects of serotonergic polymorphisms are associated with individual differences and contextual variations in attachment dimensions over time in emerging adults. Study 1 utilized a cross-sectional design in college students (N = 1088, mean age = 22.71 ± 2.86 years). The results showed significant correlations between a higher cumulative genetic score and elevated levels of attachment anxiety and avoidance. Study 2 employed a three-wave longitudinal design in a cohort of freshmen (N = 523, mean age = 19.54 ± 1.86 years at wave 1). The results demonstrated that a higher genetic score was associated with both higher levels and greater variability in attachment dimensions compared to a lower genetic score. These findings suggest that the cumulative genetic effects of serotonergic polymorphisms contribute to individual differences and dynamic processes in attachment dimensions in emerging adults.

A systematic review of measures of adult disorganized attachment

BACKGROUND

Disorganized attachment has been identified as an important factor in the development and maintenance of mental health problems. Further research is required to understand the mechanism by which this attachment pattern predisposes individuals to develop, and maintain, personal and social difficulties and mental health problems utilizing valid and reliable measurement tools. The assessment of adult disorganized attachment is therefore important for both applied psychologists and researchers.

METHOD

We conducted a systematic review using the COSMIN guidelines to identify and critically appraise instruments which measure adult disorganized attachment. A systematic database search was performed using MEDLINE, EMBASE, Web of Science, PsychInfo and CINHAL in accordance with PRISMA guidelines.

RESULTS

Database searching provided 5757 results, with 18 measures identified across 27 eligible papers which were critically evaluated. Measurement properties were promising for the Childhood Disorganization and Role Reversal Scale, Psychological Treatment Inventory-Attachment Styles Scale, Attachment Style Questionnaire - Short Form and the Adult Attachment Interview. However, overall, due to inconsistent quality of methodology and reporting of results, it is challenging to reach sufficient conclusions and suggestions regarding the best instrument to use to measure adult disorganized attachment.

CONCLUSION

The Childhood Disorganization and Role Reversal Scale, Psychological Treatment Inventory-Attachment Styles Scale. Attachment Style Questionnaire-Short-Form and Adult Attachment Interview are the best available measures of disorganized attachment in adulthood. This review highlights the need for further psychometric testing of existing measures, or development of new instruments, grounded in sound methodology.

Secure Attachment Representation in Adolescence Buffers Heart-Rate Reactivity in Response to Attachment-Related Stressors

To date, we know very little about the effects of the differences in attachment classifications on the physiological correlates of stress regulation in adolescent age groups. The present study examined for the first time heart rate (HR) and heart rate variability (HRV) during an attachment interview in adolescents. HR and HRV data were collected during a baseline assessment as well as during the administration of the Adult Attachment Projective Picture System (AAP) in a community-based sample of 56 adolescents (26 females and 30 males, mean age = 16.05 years [SD = 1.10]). We additionally used the Adult Attachment Interview (AAI) in 50% of our sample to test the convergent validity. Adolescents with a secure attachment representation showed a higher HRV from baseline to the AAP interview compared to those with an insecure-dismissing (Ds) and the unresolved group. A comparison between the two insecure attachment groups showed no significant difference related to HR and HRV. Cohen’s Kappa (κ = 0.81) revealed an almost perfect agreement between the AAP and the AAI for the four-group classification. Our results indicate that adolescents with a secure attachment representation are more capable of dealing with attachment-related distress which is represented in higher HRV during an attachment interview.

Attachment-Related Representations and Suicidal Ideations in Nonsuicidal Self-Injury Adolescents with and without Suicide Attempts: A Pilot Study

OBJECTIVES

Consistent with the debate surrounding the association between nonsuicidal self-injury (NSSI), suicidal intent, and suicidal behavior, and between NSSI and dysregulation processes, we attempted to analyze suicide intent and emotion dysregulation in NSSI adolescents, in the framework of the attachment representations and exploring these clues of emotion dysregulation characteristics of insecure attachment. Furthermore, we intended to focus on these attachment-related segregated systems regarding death and suicidal ideations, to explore how differently they would characterize self-injuring adolescents with and without suicide attempts.

METHODS

Thirty-four NSSI inpatient adolescents, 17 with suicide attempts, 17 without suicide attempts, and 17 healthy controls (age 11-17) were assessed using Adult Attachment Projective, which allows for the classification of attachment status and related emotion dysregulation and segregated systems.

RESULTS

The majority of the NSSI group with and without suicide attempts showed unresolved (disorganized) attachment-related representations and clues of damaged reflective functions, whereas only the NSSI with suicide attempts showed clues of impaired interpersonal relationships. The two clinical groups used words expressing suicidal intent, whereas the healthy group did not.

CONCLUSIONS

Therapists are encouraged not to underestimate suicidal ideation in NSSI regardless of whether or not they have already attempted suicide.

Genes and environment in attachment

In the last two decades, there has been increasing research interest in disentangling the contribution of genetic and environmental factors to individual differences in attachment, and in identifying the genes involved in shaping attachment. Twin studies suggest that as attachment changes during the course of development, genetic factors may play a progressively more important role, while shared environmental effects might decrease. However, most of this literature is limited by low power, measurement issues, and cross-sectional design. The findings of molecular genetic studies are, overall, inconclusive. The literature on main genetic effects and gene-by-environment interactions on attachment is filled with inconsistent and unreplicated findings. Also, most studies are underpowered. Challenges for future research are to identify the unshared environmental mechanisms involved in shaping attachment, and to better elucidate the genes involved and their interaction with the environment. Some pioneer studies suggested that the incorporation of epigenetic processes into G × E interaction models might represent a promising future way for investigating the complex, dynamic interplay between genes, environment, and attachment.

Adult attachment representations and depressive symptoms: A meta-analysis

BACKGROUND

Attachment theory has long argued that insecure and disorganized attachment representations are associated with vulnerability to psychopathology in general, and depressive symptoms in particular. However, studies assessing the link between insecure and disorganized attachment and depressive symptoms report inconsistent results. The primary aim of this meta-analysis was to examine the extent to which adult attachment representations are associated with depressive symptoms.

METHODS

We conducted a literature search for published studies using PsycINFO, MEDLINE, and ProQuest in March 2017, identifying 55 samples (N = 4,386). Eligible studies assessed depression using a well-validated self-report or clinical diagnostic measure of depression and attachment using the Adult Attachment Interview.

RESULTS

Results demonstrated that insecure individuals had higher levels of depression than secure-autonomous individuals (d = 0.21, 95% CI [0.08-0.33]). Specifically, insecure-preoccupied individuals (d = 0.48, 95% CI [0.30-0.65]), but not insecure-dismissing individuals (d = 0.09, 95% CI [-0.03-0.22]), exhibited significantly more depressive symptoms than the secure-autonomous individuals. Additionally, unresolved adults had higher levels of depression than adults with organized attachment classifications (d = 0.29, 95% CI [0.13-0.44]).

LIMITATIONS

Due to the nature of the studies reviewed, causal inferences regarding the links found between adult attachment representations and depressive symptoms may not be drawn. Further, the aggregate effect sizes do not solely reflect the magnitude of the association between attachment representations and clinically-diagnosed major depressive disorder.

CONCLUSIONS

The results of this meta-analysis have important conceptual and practical implications for attachment-based prevention and intervention efforts, as they suggest that attachment representations, specifically insecure-preoccupied and unresolved, are associated with depressive symptoms in adulthood. Future research using longitudinal and intervention-based designs should examine the extent to which insecure-preoccupied and unresolved attachment lead to increased depressive symptoms, as well as the mechanisms by which these attachment patterns across the life span may increase vulnerability to depressive symptoms in adulthood.
