Exploring the efficacy of memory specificity training on depression among Iranian adolescents: a comparative analysis of online vs. in-person delivery

Depression in adolescence is common worldwide, with the burden being highest in low- and middle-income countries. This study assessed the efficacy of in-person Memory Specificity Training (MeST) and computerized MeST (c-MeST) as cognitive training programs aimed at addressing depression among Iranian adolescents. A secondary aim was to evaluate the efficacy of MeST and c-MeST on autobiographical memory specificity, emotion regulation and cognitive control. Ninety Iranian male adolescents (aged 13–18 years) with depression were randomly assigned to three groups; MeST group (n = 30), c-MeST group (n = 30) and the non-active control group (n = 30). Participants completed the Beck Depression Inventory-II, Autobiographical Memory Test, Cognitive Emotion Regulation Questionnaire, Wisconsin Card Sorting Test and Stroop Color and Word Test. The groups underwent either MeST and c-MeST. All the assessments were re-conducted after the intervention (post-intervention) and at 1-month post-intervention (follow-up). The in-person MeST group exhibited significantly higher autobiographical memory specificity at post-intervention and follow-up compared to the c-MeST group. Both groups demonstrated significantly lower levels of depression at post-intervention and follow-up. Both groups showed improvements in emotion regulation and cognitive control, which were found to mediate improvements in depression symptomatology. c-MeST and MeST appear promising brief interventions for the treatment of depression among adolescents in Iran.

Cognitive vulnerabilities and depressed mood in acquired brain injury

ABSTRACT Acquired Brain Injury (ABI), an important cause of long-term disability, is associated with increased rates of depression in addition to common cognitive and physical consequences. Past research has linked post-ABI depression to injury severity (e.g., extent of physical or cognitive impairment) and premorbid mood problems. In the general (non-ABI) population, depression is associated with cognitive vulnerabilities that have informed the development of psychological interventions. In this observational study in a heterogeneous sample of individuals with chronic stage ABI, we examine two cognitive vulnerabilities – dysfunctional attitudes (DAs) and autobiographical memory specificity – and explore whether these are linked to depression symptoms and ongoing cognitive difficulties as in the general population. Compared to control participants, individuals with an ABI demonstrated increased endorsement of DAs and reduced specificity of autobiographical memory recall. Within the ABI group, cognitive vulnerability–depression symptom correlations were detected for an explicit measure of DAs, but not for a more implicit DA measure or for autobiographical memory specificity. While individual differences in injury severity and other factors likely obscured subtle relationships between mood and cognitive vulnerabilities, evidence of these vulnerabilities may be relevant to changes in identity and psychological interventions that target low mood in ABI.

Specificity and integration of meaning in self-defining memories of breast cancer survivors: clinical reflections to promote a narrative identity integration.

Potential traumatic events, such as breast cancer, can influence autobiographical memory (AM), interrupting the continuity of narrative identity. AM is based on a hierarchical search across different levels of specificity that are indexed from top to bottom when a memory is retrieved. In the breast cancer field, non-specific AMs are an observed clinical phenomenon. In particular, breast cancer survivors report issues related to self-defining memories (SDMs), specific and significant AMs that evoke strong emotions and sensory details at the time of memory. SDMs are linked to life goals and facilitate adaptation to critical experiences, preserving the continuity of identity. This study explored the narrative identity integration process of breast cancer survivors, analyzing themes, specificity, and integrative meaning in SDMs. Ten women participated in an online group support program centered on the integration of AMs linked to the cancer journey. Participants were asked to assess their body image perceptions, filling out an online survey three times, in which they had to report three SDMs each time. A reflexive thematic analysis of the SDMs identified three main themes: the onset of breast cancer; the labeling of negative emotions, and changes in the body. The results indicated inhibited retrieval of specific episodes, fostering a progressive failure in memory characterization and the concurrent meaning-making process. Participants struggled with connecting the memories to insights regarding their self and life, as well as relating the memories to external conditions and other individuals. Further studies might examine the impact of these difficulties on the psychological adjustment of BC long-term survivors. They could also explore cognitive reconstruction by reframing the memories and re-evaluating their traumatic meanings.

Direct access to specific autobiographical memories is lower in healthy middle‐aged to older adult Apolipoprotein E ε4 carriers compared to non‐carriers

AbstractRecent research suggests that the retrieval of autobiographical memories among cognitively healthy middle‐aged and older adults is sensitive to the Apolipoprotein E ε4 (APOE4) allele, a genetic marker that increases the risk of Alzheimer's disease (AD) dementia. However, whether the APOE4‐associated alteration in autobiographical memory retrieval encompasses rapid (i.e. direct retrieval) or iterative (i.e. generative retrieval) processes remains unclear. In the present study, 39 APOE4 carriers and 45 non‐carriers (ages 60–80) who scored within normal limits on neuropsychological testing were cued to generate specific autobiographical events. We examined group differences in direct and generative retrieval and correlated direct and generative retrieval rates with performance on neuropsychological tests. Direct retrieval rates were lower in the APOE4 carriers compared to non‐carriers. Episodic memory positively correlated with direct retrieval rates across the sample, though this relationship became non‐significant when factoring in age and sex. There were no significant findings related to successful generative retrieval rates and its efficiency. In summary, compared to non‐carriers, cognitively unimpaired middle‐aged to older adult APOE4 carriers demonstrated greater difficulty, rapidly reconstructing specific autobiographical events without the support of semantic memory, suggesting that early autobiographical memory retrieval processes demonstrate vulnerability to AD‐related risk factors.

Evaluation of autobiographical memory specificity during psychodynamic psychotherapy in patients with depression: A longitudinal study

Evaluation of autobiographical memory specificity during psychodynamic psychotherapy in patients with depression: A longitudinal study

Language and autobiographical memory development from 5 to 12 years: A longitudinal perspective

The main aim of this study, with two repeated measurements, was to analyze the development of autobiographical memory in a sample of 78 Spanish participants at ages 5 (Time 1; M = 62.43 months, range: 50–74 months) and 12 (Time 2; M = 142.71 months, range: 132–155 months). Data were collected on autobiographical memory and verbal functions. We analyzed the relation between language and autobiographical memory specificity from a longitudinal perspective and assessed the indirect effect of vocabulary in the relationship between age and specific memory at both temporal moments. The results showed that language skills were positively related with autobiographical memory specificity at preschool age, but not at the second measurement. Furthermore, vocabulary scores appear to mediate the relationship between age and autobiographical specificity when children are in the preschool years, but not later. These findings agree with previous research that consider preschool age to be a crucial period for the development of autobiographical memory and its relations with language, but once basic command of language is acquired, linguistic differences impact much less on individual differences in autobiographical specificity.

Meta-memory (prediction) of specific autobiographical recall: An experimental approach using a modified autobiographical memory test.

Autobiographical memory specificity is known to contribute to better mental health, social problem-solving, and episodic future thinking. While numerous studies have addressed variables that affect autobiographical memory specificity, little is known regarding the meta-memory processes that underpin memory retrieval. In this study, we introduced two meta-memory constructs, ease of retrieval judgments and anticipation of negative emotion evoked, which potentially affect autobiographical memory specificity. Participants (N = 109) first rated the ease of retrieval and anticipated emotions for positive and negative words used in a subsequent autobiographical memory test. We used the Optional Instructions of the Autobiographical Memory Test, in which participants were instructed that "specific memories are better, but other memories are permissible," allowing them to adjust how much cognitive effort they spent on generative retrieval after a failure of direct retrieval. They also self-judged whether each retrieval was generative (using additional cues with cognitive effort) or direct (immediate recall without much cognitive effort). Results showed that for generative retrieval, ease of retrieval was associated with greater specific and general memories and fewer omissions. A more negative anticipated emotion was associated with fewer specific memories and greater omissions, but was not with general memories. These results suggest that low retrievability and anticipated negative emotion prevent individuals from devoting efforts to generative retrieval. The lack of association between anticipated negative emotion and general memory calls into question the functional avoidance hypothesis regarding autobiographical memory specificity. We discussed how participants judged these meta-memories and directions for future research.

Recall of Autobiographical Memories Following Odor vs Verbal Cues Among Adults With Major Depressive Disorder

Major depressive disorder (MDD) is associated with deficits in autobiographical memory (AM) recall, which is thought to stem from disruptions in effortful recall. Understanding whether these deficits are mitigated when recall is stimulated more directly, such as by odor cues, could inform therapeutic interventions for MDD. To evaluate whether deficits in specific AM recall in MDD are mitigated when odor cues vs word cues are used to prompt memory. This cross-sectional study assessed recall of specific AMs in response to both odor cues and word cues (in a randomized, counterbalanced order) in a repeated measures design. Data were collected between September 2021 and November 2022. The study took place at the University of Pittsburgh School of Medicine in Pennsylvania and included adults with a primary diagnosis of MDD, according to the Mini International Neuropsychiatric Interview. Data were analyzed from January to June 2023. The primary outcome measure was the percentage of specific AMs recalled in response to odor-cued memories vs word-cued memories. Additional outcome measures included ratings of arousal, vividness, repetition, and recall response time for odor-cued memories vs word-cued memories. Thirty-two adults (mean [SD] age, 30.0 [10.1] years; 26 [81.3%] female; 6 [18.8%] male) with a primary diagnosis of MDD completed the study. Participants recalled more specific AMs for odor cues than word cues (mean [SD], 68.4% [20.4%] vs 52.1% [23.3%]; Cohen d, 0.78; P < .001). Additionally, odor-cued recall was rated more arousing (mean [SD], 3.0 [0.8] vs 2.6 [0.7]; Cohen d, 1.28; P < .001) and vivid (mean [SD], 3.3 [0.7] vs 3.0 [0.7]; Cohen d, 0.67; P < .001), and was slower than word-cued recall (mean [SD], 14.5 [3.6] vs 8.9 [3.4] seconds; Cohen d, 1.18; P < .001). When compared with the population mean for word cues in healthy controls (80%), participants recalled fewer specific memories in response to words (Cohen d, 1.18; P < .001), supporting the presence of overgenerality. Notably, the percentage of specific memories recalled in response to odor cues did not differ from the healthy control population mean (Cohen d, 0.26; P = .15). In this cross-sectional study, adults with MDD recalled more specific AMs in response to odor cues compared with word cues. This study suggests that AM deficits may only be observed when verbal cues are used and provides a potential new method for increasing specific AM recall in patients with MDD.

Relationship between personal recovery, autobiographical memory, and clinical recovery in people with mental illness in the acute phase

AimNarratives are important in psychiatric rehabilitation. People with a psychiatric diagnosis find it difficult to recall specific autobiographical memories of events that lasted less than a day. Although personal narratives play a central role in personal recovery, the factors influencing personal and clinical recovery, such as psychiatric symptoms and cognitive function, have not been fully explored. Therefore, this study examined the associations between personal recovery and autobiographical memory, age, psychiatric symptoms, and neurocognitive function. MethodThe Self-Identified Stage of Recovery, Parts A and B (SISR-A, SISR-B), Autobiographical Memory Test (AMT), Japanese version of the Brief Assessment Scale of Schizophrenia Cognitive Function, and Brief Psychiatric Symptom Rating Scale were administered to 40 individuals with psychiatric disorders who were undergoing psychiatric rehabilitation. ResultsA significant positive correlation was found between the total number of specific memories in the AMT and total SISR-B scores. A binary logistic regression analysis revealed that the total number of specific memories, especially high responsiveness to negative cue words, significantly predicted greater personal recovery. Age, psychiatric symptoms, and neurocognitive function did not significantly predict higher personal recovery. ConclusionIn psychiatric rehabilitation, negative episodes should be treated with caution; however, they may also facilitate personal recovery.

Neural substrates of specific and general autobiographical memory retrieval in younger and older adults

Healthy aging is associated with a shift away from the retrieval of specific episodic autobiographical memories (AMs), towards more general and semanticized memories. Younger adults modulate activity in the default mode network according to the episodic specificity of AM retrieval. However, little is known about whether aging disrupts this neural modulation. In the current study we examine age-related changes in the modulation of whole-brain networks in response to three tasks falling along a gradient of episodic specificity. Younger and older adults retrieved specific (unique) AMs, general (routine) AMs, and semantic (general knowledge) memories. We found that both younger and older adults modulated default mode regions in response to varying episodic specificity. In addition, younger adults upregulated activity in several default mode regions with increasing episodic specificity, while older adults either did not modulate these regions, or downregulated activity in these regions. In contrast, older adults upregulated activity in the left temporal pole for tasks with higher episodic specificity. These brain activation patterns converge with prior findings that specific AMs are diminished in episodic richness with age, but are supplemented with conceptual and general information. Age-related reductions in the modulation of default mode regions might contribute to the shift away from episodic retrieval and towards semantic retrieval, resulting in reduced episodic specificity of personal memories.

Specific autobiographical memories are a resource for identity strength among mature but not emerging adults

ABSTRACT Four studies, three pre-planned on Open Science Framework, with 2296 participants explored the potential role of recollecting autobiographical memories in enhancing the sense of identity. Among emerging adults (college students under age 25), recollecting important autobiographical memories did not strengthen sense of identity. Autobiographical memories failed to strengthen identity among emerging adults despite inducing low self-clarity first; despite attempts to prime self-consistent memories by having emerging adults report their stable self-aspects first; and despite attempts to inspire self-event connections by asking emerging adults to explain how the memories exemplified something enduring about the self. Among mature adults (age 25 and older), recollecting important autobiographical memories strengthened sense of identity. Identity was strengthened regardless of whether mature adults were asked to explain how the memories exemplified something enduring about the self. Differences in types of memories or motivation did not account for the differential effects of recollecting autobiographical memories in identity. In short, mature adults appear to readily use autobiographical memories as a resource for identity in a way that emerging adults have not yet mastered.

When having photographs of events influences the visual perspective of autobiographical memories

AbstractPhotographs are frequently taken to preserve memories of events from the personal past, but they can also bias how we remember. For example, photographs often capture events from a novel visual perspective (e.g., seeing ourselves in the image). Here, we examined how the presence of the self in photographs influences autobiographical memories. Participants provided subjective ratings for specific autobiographical memories, and then, following the retrieval phase, they were asked to indicate whether they had photographs for these memories and the nature of these images. Across three studies (N = 378), we found that autobiographical memories that participants reported the presence of photographs containing the self were more likely to be remembered from an observer‐like perspective than memories with photographs in which the self was not visible. These findings have important implications for understanding how the growing number of photographs taken in everyday life biases the perspective of our memories.

Autobiographical memory in chronic schizophrenia: A follow-up study

Chronic schizophrenia is a very disabling disease and patient’s social integration remains difficult. One important aspect is autobiographical memory (AM) as it is impaired in schizophrenia and highly correlated to patient’s outcome, since its closely linked to self and identity. Reduced specificity and lack of details are characteristics of patients′ AM, but its longitudinal course in schizophrenia remains unclear. We examined 21 patients who underwent our protocol twice with an interval of 7 years. AM was assessed using a semi-structured interview, covering four periods of life and addressing semantic knowledge and autobiographical episodes as well as their details. The results can be divided into three parts, separating semantic memories, specific autobiographical memories and details describing the latter. While a significant deterioration of semantic AM over time could be revealed, the specificity of the free recalled autobiographical episodes remained rather stable – albeit on a low level. In contrast, unique events were remembered with significantly less details at follow-up than at the first examination. While floor-effects given a relatively small number of unique events have to be considered, semantic AM and episodic details seem to be a valuable target for AM remediation given their further deterioration over time.

P101 Brain Amyloid Burden and Autobiographical Memory in Obstructive Sleep Apnoea: A Cross-sectional Study.

Abstract Introduction Emerging literature reports an increased risk of Alzheimer’s disease in individuals with obstructive sleep apnoea (OSA). Established characteristics of Alzheimer’s disease include increased brain amyloid burden and impairment to episodic and autobiographical memory. Investigating these constructs in individuals with clinically confirmed OSA will contribute to understanding of OSA and neuronal implications. Aim The aim of the study was to explore the relationship between brain amyloid burden and autobiographical memory in cognitively-healthy individuals with OSA. Methods Thirty-four participants with OSA (mean age=57.7, SD=8.5, 19 males), and 12 controls (mean age=57.1, SD=8.1, 6 males) participated in the study. Participants underwent a 11C-PiB positron emission tomography (PET) scan to quantify amyloid burden, and an assessment of autobiographical memory. Brain amyloid burden was quantified using the standardised uptake value ratio (SUVR), and the Autobiographical Memory Test (AMT) was used to assess the ability of participants to recall specific memories from their life. Results Individuals with OSA recalled significantly fewer specific autobiographical memories (M=6.66, SD=2.91) compared to controls (M=10.25, SD=2.09, t(45)=-3.930, p&amp;lt;.001). There was no significant difference in SUVR between groups, t(44)=1.465, p=.150. Recall of non-specific memories was significantly positively correlated with SUVR, r=.331, p=.026. Discussion Levels of brain amyloid burden did not differ significantly between groups however the results support existing literature suggesting amyloid burden is associated with autobiographical memory in individuals with OSA. Longitudinal studies investigating the trajectory of these constructs in the context of disease development should be conducted to further explore the impacts of OSA.

Future thinking and anticipatory pleasure in adolescents with major depression: Association with depression symptoms and executive functions.

Impairments in episodic future thinking and anticipatory pleasure were noted to explain the depressive symptoms in adults however similar studies are not there in adolescents. This study examined whether there are impairments in episodic future thinking and anticipatory pleasure in clinically-depressed adolescents as compared to non-depressed adolescents, and their association with depression when controlled for executive functions and anxiety symptoms among the depressed adolescents. The study included 29 adolescents with major depression and 29 adolescents from local schools through convenient sampling technique. All the participants were assessed with standardized measures of depression and anxiety, episodic future thinking, anticipatory pleasure and executive functioning. Depressed adolescents significantly differed from the non-depressed adolescents in autobiographical memory specificity, anticipatory pleasure, and specific dimensions of executive functions. The ANCOVAs indicated executive function slightly attenuated group differences on future specificity which were still non-significant (all p's > .05). For memory specificity and for anticipatory pleasure, group differences were still significant at p < .05 level. Adolescents with major depressive episode may display similar, but less pronounced, impairments in future thinking than what is previously reported in adults. Though, autobiographical specificity is prominent. The deficits are attributable to depression than executive functioning deficits.

The influence of induced dysphoria on autobiographical memory specificity and social problem solving: Examining the role of executive function

Negative mood induction leads to reductions in autobiographical memory specificity (AMS) and social problem-solving (SPS). The aim was to establish if executive function contributes to changes in AMS and SPS following negative mood induction. Forty-four participants (study 1) completed the autobiographical memory test and measures of executive function (letter & category fluency) before and after a positive or negative mood induction (MI). Forty participants (study 2) completed the means-end problem solving task (MEPS) and (letter & category) fluency tasks before and after a positive or negative MI. In study 1, participants exhibited impaired AMS and fluency performance following a sad MI. Decrease in memory specificity pre-to post-MI was related to reductions in happy mood and letter fluency. In study 2, participants exhibited poorer performance on the MEPS and fluency tasks following a sad MI. Decreases in the number of relevant solutions generated on the MEPS pre-to post-MI was linked to increases in sad mood and decreases in letter fluency. In both studies, the influence of mood became non-significant once the effect of executive function was accounted for, which suggests that changes in AMS and SPS in response to induced mood were related to concomitant changes in executive function.

Social operant conditioning of autobiographical memory sharing

The memories for past autobiographical experiences that we share can influence relationship formation and consolidation with important implications for our mental health. However, little is known about how people's responses to our memories can influence subsequent memory sharing. Previous research examined how operant processes (i.e., punishment with aversive sounds) influence the sharing of memories for specific events from our past. Understanding the (social) mechanisms associated with difficulty sharing specific autobiographical memories is important given the association between these difficulties and a range of psychiatric diagnoses. We investigate the effects of verbal and non-verbal social operants on the willingness to share specific autobiographical memories. Participants shared memories with a confederate who coded their memories as specific or non-specific and responded in either an engaged/attentive, dismissive manner or gave no feedback depending on participants' assigned condition. Participants who were reinforced for sharing specific memories and punished for sharing non-specific memories, were more likely to share specific than non-specific memories compared to those who received no feedback. Reinforcement alone was not sufficient for modifying specificity. The ways that we respond to people when they share memories with us can influence their subsequent willingness to share specific events from their past.

Improving older adults' autobiographical memory through video-conferencing intervention during COVID-19.

Autobiographical memory (AM) is valuable not only as an indicator of mental health and cognitive function, but also as a target of therapeutic intervention for older adults. In the context of the COVID-19 pandemic, the demand for online psychosocial interventions and assessment services has sharply increased. Thus, the present study examined the effectiveness of videoconferencing AM (vAM) intervention using the Ecological Momentary Assessment (EMA) method in addition to the traditional paper-and-pencil assessment among samples of community dwelling older adults. Twenty-seven older adults (aged 66-86years) participated in a vAM intervention composed of 4 weekly 90-min sessions. The primary outcome was AM specificity, with secondary outcomes as depressive symptom and cognitive function, measured before and after the intervention. In addition, daily emotions were measured through EMA over 4weeks of intervention. The EMA data were analyzed using a multilevel analysis. The results showed low dropout rates (7%) and high EMA response rates (85%). Autobiographical memory specificity increased (Cohen's d=0.678), and the level of depression declined significantly (Cohen's d=0.375) after the program. Additionally, measures assessing cognitive function, such as Seoul Verbal Learning Test and DSC (Digit Symbol Coding), showed significant improvements. The EMA results indicated a decrease in the intensity and proportion of negative emotions experienced during the program. This study is the first to utilize videoconferencing and EMA to deliver an AM intervention targeting older adults. The intervention was effective in improving mental health and cognitive function, including AM in older adults. Additionally, EMA was found to be a feasible tool for use in older adults.

A Meta-Analysis of the Influence of Cue Valence on Overgeneral Memory and Autobiographical Memory Specificity Among Youth.

Overgeneral memory (OGM), or difficulty recalling specific memories when recounting autobiographical events, is associated with psychopathology. According to functional avoidance theory, OGM-or reduced autobiographical memory specificity (AMS)-may serve as an emotion regulation strategy that aids in the avoidance of painful, negative memories (Sumner,2012; Williams et al., 2007). Some researchers argue that there may be a valence effect for OGM, such that there is a higher frequency of overgenerality when recalling negative memories compared to positive memories. Although not supported among adults, valence effects may be present among children and adolescents if OGM initially develops in response to negative cues and then generalizes to all memory recall over time. This meta-analysis examined differences in child and adolescent OGM and AMS based on cue valance; standardized mean differences between negative and positive valence cues for OGM and AMS indices were calculated. Following PRISMA guidelines, a systematic literature search resulted in 26 studies assessing OGM and 30 assessing AMS. There was a significant effect of valence on OGM (d = 0.17, p = 0.01) and AMS (d = -0.20, p = 0.01). There was a higher frequency of overgeneral responses to negative cue words than positive cue words. Similarly, there was a higher frequency of specific responses for positive cue words than negative cue words. Subgroup analyses considering differences in valence effects by participant age (childhood vs. adolescence), sample type (clinical vs. community), and task instructions (verbal vs. written) were not significant. Theoretical advancements for our understanding of OGM and AMS and clinical implications are discussed.

Autobiographical memory specificity and restrained eating: examining the influence of priming with images of healthy and unhealthy foods

BackgroundDietary restraint has been linked to deficits in the ability to recall detailed memories of personally experienced events (referred to as autobiographical memory specificity). As priming with healthy foods increases the salience of restraint it would be expected to lead to greater deficits in memory specificity.ObjectiveTo determine if priming word cues with images of healthy or unhealthy foods would influence the specificity of memory retrieval, and if deficits in memory specificity would be more evident in those reporting higher levels of dietary restraint, or currently dieting.MethodsSixty female undergraduates self-reported if they were currently dieting and completed measures of mood, restraint, and disinhibition, and a modified version of the autobiographical memory task. Participants were presented with positive and negative words (unrelated to eating concerns) and asked to retrieve a specific memory in response to each cue. A food image was shown prior to each word cue; half of the participants were primed with images of healthy foods and half with images of unhealthy foods.ResultsAs expected, participants primed with healthy foods retrieved fewer specific memories than did those primed with unhealthy foods. However, neither restraint nor current dieting behaviour was associated with memory specificity.ConclusionsDifferences in memory specificity between the priming conditions cannot be explained in terms of increased salience of restraint. However, it is plausible that unhealthy images led to an increase in positive affect, which in turn improved memory specificity.Level of evidenceLevel I: Evidence obtained from: at least one properly designed experimental study.
