Rumination and overgeneral autobiographical memory as mediators of the relationship between attachment and depression

Attachment patterns and autobiographical episodic memory functioning: A systemic review of adult studies to advance clinical psychological science

Patterns of insecure attachment are associated with psychopathology but the mechanisms involved remain poorly understood. Cognitive science proposes that attachment patterns are influenced by the autobiographical memory system and in turn influence its ongoing functioning. Disturbances in autobiographical memory represent cognitive risks for later emotional difficulties. We systemically reviewed 33 studies (in 28 articles) examining the association between attachment patterns and autobiographical episodic memory (AEM) in individuals from the age of 16 (i.e., from young to older adulthood). Attachment patterns were associated with key areas of AEM phenomenology, including intensity and arousal; detail, specificity, and vividness; coherence and fragmentation; and accuracy and latency. These associations appeared to be moderated by contextual and individual factors; mediated by emotional regulation and schema-based processing; linked to mental health outcomes. Attachment patterns may also influence the impact of certain AEM-based manipulations. We conclude by providing a critical discussion and a research agenda for bringing together attachment, memory, and emotion, with a view to promote mechanism-driven treatment innovation in clinical psychology.

The Relationship between Attachment Styles and Compulsive Online Shopping: The Mediating Roles of Family Functioning Patterns

The rapid expansion of e-commerce has made the buying experience faster, potentially anonymous, and without limits of space and time. While this may produce benefits, for some individuals, online shopping can become an addiction. Therefore, the present study aimed to explore the psychological factors that may be associated with Compulsive Online Shopping, with a specific focus on the role of Attachment Styles and Family Functioning patterns as risk or protective factors. The study involved a sample of 306 participants (M_age = 31.86 years, SD = 11.925) who filled out an online survey consisting of the Compulsive Online Shopping Scale, Relationship Questionnaire, Family Adaptability and Cohesion Evaluation Scales-IV, as well as a demographic questionnaire. The results showed two significant parallel mediation models. In the first one, Secure Attachment was negatively and significantly related to Compulsive Online Shopping, with the mediation of Cohesion and Enmeshed Family Functioning. In the second one, Fearful Attachment was positively and significantly related to Compulsive Online Shopping, with the mediation of Cohesion and Enmeshed Family Functioning. Important implications for preventive activity and tailored interventions may emerge from these data.

Mediational mechanisms involved in the relation between attachment insecurity and depression: A meta-analysis

BACKGROUND

Several studies have investigated the intermediate variables or mediators through which attachment insecurity influence the development of depression. However, there has not been a systematic synthesis of this literature to date. The current meta-analytic review aimed at identifying such mediators and quantifying their effect size.

METHODS

We systematically searched Medline, Pubmed, Psycinfo, Embase, Proceedings Web of Science and ProQuest Dissertations & Theses Global up until May 2019. 108 studies met inclusion criteria (i.e., investigated intermediate variables that explain the effect of attachment insecurity [exposure] on depressive symptoms [outcome]). Standardized regression coefficients of the indirect and total paths of mediation models of 80 studies were pooled using the inverse of their variance as a weight. Studies were coded and ranked for quality.

RESULTS

Dysfunctional attitudes (β = 0.10, 95% CI = 0.01 to 0.20), self-criticism (β = 0.17, 95% CI = 0.04 to 0.28), low self-compassion (β = 0.16, 95% CI = 0.02 to 0.29), and cognitive hyperactivating regulation strategies (β = 0.13, 95% CI = 0.05 to 0.20), such as repetitive thinking (β = 0.17, 95% CI = 0.07 to 0.28), and particularly, brooding rumination β = 0.20, 95% CI = 0.07 to 0.32), mediated the association between insecure attachment and depressive symptoms. Indirect effects were only significant among adult populations.

LIMITATIONS

The methodological quality of studies was mostly moderate to low and analyses revealed considerable heterogeneity.

CONCLUSION

Our findings support the direct targeting of cognitive-emotional psychological mechanisms in prevention programs and treatment of depression. More longitudinal studies are needed to clarify the interplay of such mediators along with other interpersonal factors between insecure attachment and depression.

The Role of Metacognitions on the Relationship Between Adult Attachment and Mood Symptoms in Individuals with Obesity

In order to examine psychological mechanisms contributing to the development and maintenance of mood symptoms experienced by individuals with obesity, this study focused on the mediator role of metacognitions in the relationship between adult attachment dimensions (anxious and avoidant) and mood symptoms (depression and anxiety). A 184 individuals with Body Mass Index (BMI) of 30 or above completed a battery of instruments including measures of attachment styles, metacognitive beliefs and processes, depression, and anxiety symptoms. Multiple mediation analyses with bootstrapping demonstrated that while attachment anxiety was predictive of greater levels of depression and anxiety through the effect of beliefs about uncontrollability and dangerousness of worry, metacognitive factors have no mediator role in the relationship between avoidant attachment and mood symptoms. Findings suggest in particular that anxious attachment and metacognitive characteristics might be considered in case conceptualizations and intervention strategies for the psychological problems experienced by individuals with obesity.Level of Evidence: Level V: Descriptive (cross-sectional) study.

Boosting attachment security to cope with threats: Behavioral and ERPs findings

Attachment security describes a sense of safety and security felt by individuals and promotes mental health. The mechanism by which attachment security buffers against psychological threat remains unclear, however. Here, we explored how attachment security attenuates the response to threatening information using a signal detection theory (SDT) and event-related potentials (ERPs) approach. Participants were assigned to an attachment security priming condition or a control condition. After a priming procedure, behavioral data and electroencephalography (EEG) signals were recorded while participants categorized threatening and neutral pictures. Our behavioral results revealed that attachment security biased participant responses to categorizing the two types of pictures; participants in the control condition exhibited a tendency to categorize stimuli as threatening, whereas those in the attachment security condition tended to categorize stimuli as neutral. Meanwhile, attachment security priming modulated early attention processes, reflected by an increased P200. The findings reported here suggest that attachment security buffers against external threats by modulating individual response preferences, the effects of which manifest in the early stages of attentional processing.

Remembering the past and imagining the future: attachment effects on production of episodic details in close relationships

Attachment theories and studies have shown that Internal Working Models (IWMs) can impact autobiographical memory and future-oriented information processing relevant to close relationships. According to the constructive episodic simulation hypothesis (CESH), both remembering the past and imagining the future rely on episodic memory. We hypothesised that one way IWMs may bridge past experiences and future adaptations is via episodic memory. The present study investigated the association between attachment and episodic specificity in attachment-relevant and attachment-irrelevant memory and imagination among young and older adults. We measured the attachment style of 37 young adults and 40 older adults, and then asked them to remember or imagine attachment-relevant and attachment-irrelevant events. Participants' narratives were coded for internal details (i.e., episodic) and external details (e.g., semantic, repetitions). The results showed that across age group, secure individuals generated more internal details and fewer external details in attachment-relevant tasks compared to attachment-irrelevant tasks; these differences were not observed in insecure individuals. These findings support the CESH and provide a new perspective to understand the function of IWMs.
