Autobiographical memory specificity in child sexual abuse victims

Autobiographical memory and psychopathology: Is memory specificity as important as we make it seem?

Several decades of research have established reduced autobiographical memory specificity, or overgeneral memory, as an important cognitive factor associated with the risk for and maintenance of a range of psychiatric diagnoses. In measuring this construct, experimenters code autobiographical memories for the presence or absence of a single temporal detail that indicates that the remembered event took place on a single, specific, day (Last Thursday when I rode bikes with my son), or multiple days (When I rode bikes with my son). Studies indicate that the specificity of memories and the amount of other episodic detail that they include (e.g., who, what, and where) are related and may rely on the same neural processes to elicit their retrieval. However, specificity and detailedness are nonetheless separable constructs: imperfectly correlated and differentially associated with current and future depressive symptoms and other associated intrapersonal (e.g., rumination) and interpersonal (e.g., social support) outcomes. The ways in which the details of our memories align with narrative themes (i.e., agency, communion, identity) and the coherence with which these details are presented, are also emerging as important factors associated with psychopathology. The temporal specificity of autobiographical memories may be important, but other memory constructs warrant further attention in research and theory, especially given the associations, and dependencies, between each of these constructs. Researchers in this area must consider carefully whether their research questions necessitate a focus on autobiographical memory specificity or whether a more inclusive analysis of other autobiographical memory features is necessary and more fruitful.

A Longitudinal Investigation of the Relationship Between Trauma-Related Cognitive Processes and Internalising and Externalising Psychopathology in Young People in Out-of-Home Care

Young people in out-of-home care are at increased risk of developing a range of posttrauma mental health difficulties, including PTSD, but more commonly anxiety, depression and externalising symptoms. Cognitive models of PTSD indicate that trauma-related maladaptive appraisals, coping strategies and trauma memory qualities are key processes in the development and maintenance of PTSD, yet there has been limited investigation of the potential role of these processes in broader posttrauma psychopathology, particularly in young people who have been exposed to complex, rather than acute, trauma. We recruited 120 10-18 years olds in out-of-home care, and their caregivers, who completed assessments at two time points: baseline and 12-month follow-up. Young people completed self-report measures of trauma-related maladaptive appraisals, coping strategies and trauma-memory qualities, as well as reporting on PTSD, anxiety, depression and externalising symptoms. Carers also reported on internalising and externalising symptoms. We found that all three cognitive processes were associated with baseline self-reported internalising symptoms, with maladaptive appraisals most robustly associated with both anxiety and depression. Changes in all three processes over 12-months predicted a change in self-reported internalising and externalising symptoms, with maladaptive appraisals and coping predicting anxiety symptoms, and coping uniquely predicting depression and externalising symptoms. Effects remained after controlling for co-occurring PTSD symptoms. Findings were not replicated when using carer-reported symptoms. These findings suggest that existing cognitive models of PTSD may also usefully explain broader posttrauma depression, anxiety and externalising symptoms in young people who have experienced maltreatment and live in out-of-home care. Clinical implications are discussed.

Developmental and Intervention-Related Change in Autobiographical Memory Specificity in Maltreated Children: Indirect Effects of Maternal Reminiscing

This study examined the development of autobiographical memory specificity (AMS) in a longitudinal randomized controlled trial of 242 maltreated and nonmaltreated children (aged 36-86 months; 50.4% male; 39.7% Black, 25.9% White, 34.5% Latinx/other) and their mothers. Half of the maltreated families were randomized to receive an intervention to improve maternal reminiscing. The effects of maltreatment and the intervention on children's AMS via two indices of maternal reminiscing, sensitive guidance, and elaboration, were evaluated. Bidirectional associations between AMS and child maladjustment were also examined. Intervention-related improvement in maternal sensitive guidance 6-month postintervention (b* = .36) related to greater AMS among maltreated children 1 year later (b* = .19). These findings underscore the role of maternal sensitive guidance in facilitating AMS.

The Relevance of Cognitive Behavioral Models of Post-Traumatic Stress Following Child Maltreatment: A Systematic Review

While it is known that young people exposed to maltreatment or abuse are at elevated risk of developing post-traumatic stress disorder (PTSD), much of our current knowledge of mechanisms that link trauma to childhood PTSD is based on single-incident, often noninterpersonal, trauma. Theoretical models highlight psychological processes of appraisals, memory, and coping as important for the development of PTSD. The aim of this review was to synthesize the literature on the role of these key psychological processes in relation to PTSD in maltreated children and teens. Studies were included if they (1) identified a sample of maltreated individuals, ≤18 years old; (2) measured (a) trauma memory, (b) appraisals, or (c) post-trauma cognitive or behavioral responses; and (3) measured PTSD symptoms. The systematic search of three electronic databases (American Psychological Association PsychNet, PubMed, and Published International Literature on Traumatic Stress) resulted in the inclusion of 36 papers, which described 31 studies and 33 unique samples. The review found cognitive behavioral models of PTSD appeared appropriate for understanding outcomes following maltreatment, but further research is needed on all processes, particularly trauma memory. Overall, there remain significant gaps in our knowledge of how psychological processes link maltreatment to PTSD. There is limited evidence concerning how maltreatment-related characteristics (e.g., chronicity, duration, and type of abuse) influence psychological processes and in turn affect outcomes. This review recommends further research in this area and suggests that, at the very least, comprehensive assessment should be conducted with all young people reporting maltreatment to identify appraisals and coping strategies that will potentially impact on their ongoing adjustment.

Characterisation of self-defining memories in criminals with antisocial personality disorder

Early aversive events are key factors in the development of antisocial personality disorder (ASPD) and are known to impact the ability to produce specific autobiographical memories and to modify self-construction. The present study assessed identity construction in forensic inpatients suffering from ASPD by comparing the characteristics (specificity, integration, valence, topic and period) of self-defining memories (SDM) of persons with ASPD hospitalised in a forensic hospital to those of control participants. Offenders with ASPD had difficulty in retrieving purely specific single events and tended to recall memories comprising multiple events. In addition, they produced significantly less meaning-making from their past experiences (low integration). These characteristics of SDM could be due to a defensive process used by offenders with ASPD in which they do not integrate aversive experiences, thereby creating a vicious circle where maladjustment of their personality is maintained.

Voices of adolescent incest victims: A qualitative study on feelings about trauma and expectations of recovery

BACKGROUND

Incest, is a serious social problem facing society and children/adolescents themselves. The purpose of this study is to explore the ways adolescents talk about and give meaning to their experiences of incest concerning cultural, ethnic factors relevant to southeastern of Turkey.

METHOD

We focused on in-depth interviews of five incest victims (14-16 years girls, from low socioeconomic status in southeastern of Turkey).

RESULTS

Four key themes were constructed from the qualitative analysis: 1. Unable to understand/Delayed meaning-making: Adolescents provided definitive information about the first abuse memory but they were also unable to understand what they had experienced so they delayed meaning making. 2. Dysfunctional coping style with the incest: Adolescents told that they threatened the perpetrators in various phases of incest. 3. Avoidance of eye contact by the perpetrator: We recognized that perpetrators avoided social contact with the victim. This theme evokes dehumanizing of women during incest. 4. The urge to destroy happy memories: This theme presents data on the adolescents' expectations about recovery.

CONCLUSION

According to the themes, two fundamental therapeutic precepts could guide the treatment process for adolescent girl incest survivors: 1. Exploration of the delayed meaning making: Therapist could address dysfunctional family functioning and explain that it is normal for a child to be delayed in meaning making. 2. Recovery of the adolescent's lost self after semantic dehumanization in abuses: Therapist should help her to dispute irrational beliefs about worthlessness and to gain control of her body.

Early childhood cumulative risk is associated with decreased global brain measures, cortical thickness, and cognitive functioning in school-age children

Children exposed to multiple risk factors early in life are increasingly more likely to suffer from a host of cognitive impairments across development. However, little work has identified the neurobiological mechanisms linking early cumulative risk and cognitive functioning. The current study examined the impact of cumulative risk assessed during early childhood on neural and cognitive outcomes measured 3 years later when children were school-aged. Participants included 63 children assessed during preschool (age: M = 4.23 years, SD = 0.84) and 3 years later (age: M = 7.19 years, SD = 0.89). Early cumulative risk was defined by the presence of low family income, a single parent household, low parental education, child exposure to parental depression, child exposure to high parental hostility, and high levels of stressful life events. Children's exposure to stressors in the past year, cognitive abilities, and brain structure were assessed at follow-up. Early cumulative risk was prospectively associated with reduced total gray matter volume, cortex volume, right superior parietal and inferior parietal thickness, and poorer attention shifting and memory. Right superior parietal thickness mediated associations between early risk and recall memory. Results highlight neural variations associated with early cumulative risk and suggest potential neural pathways from early risk to later childhood cognitive impairments.

A Case of Cognitive Decline Resulting from Aging, Temporal Lobe Epilepsy, and Environmental Factors

Cognitive functioning is imperative in our daily lives. It allows us to understand, process, and react appropriately to different situations. Aging has been linked to cognitive decline. The degree and rate of cognitive decline are crucial as they differentiate normal aging from dementia or memory loss secondary to medical conditions. A 63-year-old Caucasian woman with a 50-year history of temporal lobe epilepsy experienced memory difficulties in recent years. She was admitted voluntarily to the neuropsychiatry ward for a 3-day ambulatory electroencephalogram (EEG), which reported mild bitemporal structural or functional abnormality. The patient reported subjective seizure experiences that were not reflective of seizure activity on the EEG. Possible causes included panic attacks or other anxiety experiences. Routine laboratory test and magnetic resonance imaging results were unremarkable. During her hospital stay she showed improvement in cognitive functioning. However, anxiety continued to negatively impact her memory. We hypothesized that the memory impairments could have resulted from age, psychological factors, the patient's own expectations, pressure from the environment and history of TLE. We diagnosed the patient with mild cognitive impairment and adjustment disorder with anxiety. She was discharged with seizure and anxiety medication. This report highlights the importance of both age-related and disease-related variables when diagnosing patients with cognitive decline.

Altered default mode network connectivity in adolescents with post-traumatic stress disorder

Post-traumatic stress disorder (PTSD) is characterized by intrusions, re-experiencing, avoidance and hyperarousal. These symptoms might be linked to dysfunction in core neurocognitive networks subserving self-referential mental processing (default mode network, DMN), detection of salient stimuli (salience network, SN) and cognitive dysfunction (central executive network, CEN). Resting state studies in adolescent PTSD are scarce and findings are inconsistent, probably due to differences in patient symptom severity. Resting state brain activity was measured in 14 adolescents with severe PTSD and 24 age-matched controls. Seed-based connectivity analyses were used to examine connectivity between the DMN and the whole brain, including regions from other networks (SN and CEN). The relationships of network properties with symptom dimensions (severity, anxiety and depression) and episodic memory were also examined. Analyses revealed decreased within-DMN connectivity (between PCC and occipital cortex) in patients compared to controls. Furthermore, within-DMN connectivity (between PCC and hippocampus) correlated negatively with symptom dimensions (severity and anxiety), while increased connectivity (DMN-SN and DMN-CEN) correlated positively with episodic memory measures. These abnormal network properties found in adolescent PTSD corroborate those previously reported in adult PTSD. Decreased within-DMN connectivity and disrupted DMN-SN and DMN-CEN coupling could form the basis for intrusive trauma recollection and impaired episodic autobiographical recall in PTSD.

•

Adolescent PTSD is linked to dysfunction in core neurocognitive networks.

•

Results show decreased within-DMN connectivity in patients compared to controls.

•

Within-DMN connectivity correlates negatively with severity and anxiety.

•

Increased DMN-SN connectivity correlates positively with episodic memory.

•

Disrupted connectivity may form the basis for intrusive trauma recollection in PTSD.

Reduced Autobiographical Memory Specificity Among Maltreated Preschoolers: The Indirect Effect of Neglect Through Maternal Reminiscing

Maternal reminiscing and preschoolers' (M = 5.00 years, SD = 1.11) autobiographical memory specificity (AMS) were examined among abusive (n = 24), neglecting (n = 78), emotionally maltreating (n = 32), and demographically similar nonmaltreating families (n = 74). Neglect was negatively associated with child AMS and the quantity of maternal elaborations. In a moderated mediation model, neglect was negatively associated with the quantity of maternal elaborations, which was positively associated with AMS when mothers reminisced in a coherent and sensitive manner (i.e., affective quality). In the context of high maternal affective quality, maternal elaborative quantity accounted for reduced AMS among neglected preschoolers. The findings extend observations of reduced AMS to neglected preschoolers and inform theoretical models of autobiographical memory development.

Posttraumatic Stress Disorder and Autobiographical Memories in Everyday Life

Evidence from self-reports and laboratory studies suggests that recall of nontrauma autobiographical memories may be disturbed in posttraumatic stress disorder (PTSD), but investigations in everyday life are sparse. This study investigated unintentional nontrauma and trauma memories in trauma survivors with and without PTSD (N = 52), who kept an autobiographical memory diary for a week. We investigated whether unintentional nontrauma memories show an overgeneral memory bias and further memory abnormalities in people with PTSD, and whether unintentional trauma memories show distinct features. Compared to the no-PTSD group, the PTSD group recorded fewer nontrauma memories, which were more overgeneral, more often from before the trauma or related to the trauma, were perceived as distant, and led to greater dwelling. Trauma memories were more vivid, recurrent, and present and led to greater suppression and dwelling. Within the PTSD group, the same features distinguished trauma and nontrauma memories. Results are discussed regarding theories of autobiographical memory and PTSD.

Child maltreatment, trauma-related psychopathology, and eyewitness memory in children and adolescents

Two experiments were conducted to examine eyewitness memory in children and adolescents (9- to 15-years-old) with and without known histories of maltreatment (e.g., physical abuse, exposure to domestic violence). In Experiment 1, participants (N = 35) viewed a positive film clip depicting a congenial interaction between family members. In Experiment 2, participants (N = 31) watched a negative film clip in which a family argument was shown. Younger age and higher levels of trauma-related psychopathology significantly predicted commission errors to direct questions when the positive family interaction had been viewed, but not when the negative family interaction had been shown. Maltreatment history was not a significant unique predictor of memory performance for the positive or negative film clip. Implications for a scientific understanding of the effects of child maltreatment on memory are discussed.

Recurrent headache and interpersonal violence in adolescence: the roles of psychological distress, loneliness and family cohesion: the HUNT study

Background

Recurrent headache is the most common and disabling pain condition in adolescence. Co-occurrence of psychosocial adversity is associated with increased risk of chronification and functional impairment. Exposure to interpersonal violence seems to constitute an important etiological factor. Thus, knowledge of the multiple pathways linking interpersonal violence to recurrent headache could help guide preventive and clinical interventions. In the present study we explored a hypothetical causal model where the link between exposure to interpersonal violence and recurrent headache is mediated in parallel through loneliness and psychological distress. Higher level of family cohesion and male sex is hypothesized to buffer the adverse effect of exposure to interpersonal violence on headache.

Methods

The model was assessed using data from the cross-sectional, population-based Young-HUNT 3 study of Norwegian adolescents, conducted from 2006–2008. A cohort of 10 464 adolescents were invited. The response rate was 73% (7620), age ranged from 12 and 20 years, and 50% (3832) were girls. The study comprised self-report measures of exposure to interpersonal violence, loneliness, psychological distress and family cohesion, in addition to a validated interview on headache, meeting the International Classification of Headache Disorders criteria. Recurrent headache was defined as headache recurring at least monthly during the past year, and sub-classified into monthly and weekly headache, which served as separate outcomes.

Results

In Conditional Process Analysis, loneliness and psychological distress consistently posed as parallel mediating mechanisms, indirectly linking exposure to interpersonal violence to recurrent headache. We found no substantial moderating effect of family cohesion or sex.

Conclusions

Loneliness and psychological distress seem to play crucial roles in the relationship between exposure to interpersonal violence and recurrent headache. To facilitate coping and recovery, it may be helpful to account for these factors in preventive and clinical interventions. Trauma-informed, social relationship-based interventions may represent a major opportunity to alter trajectories of recurrent headache.
