Negative Life Stress Research Articles

Dementia Disorders: A Narrative Review

This narrative review of research includes summaries of 40 papers on dementia disorders that were published during 2023. The publications of this period are primarily randomized controlled trials and systematic reviews/ meta-analyses of randomized controlled trials. A few of these are focused on the prevalence of dementia which approximated one per cent of the world’s population. Only a few studies focused on effects of dementia disorders including memory loss, discrimination, pain, depression and suicidality. Most of the studies addressed predictors of dementia disorders including neurotic personality, frequent tv/computer use and excessive exposure to metals. Loss of short-term memory and other negative experiences including negative life events, loneliness, stress and depression were also significant predictor variables in this recent literature. Physical conditions that were predictive of dementia included pain, hypertension, atrial fibrillation, multi-morbidities, inflammation, encephalitis and neuropathology. Potential underlying mechanisms included dysfunctional neurotransmitter systems (serotonergic, noradrenergic and dopaminergic) and gray matter loss in prefrontal, temporal and other regions associated with memory. Several research groups reported on effective interventions including a Mediterranean diet, plant-based diets, medicinal plants, psychedelics, second generation antidepressants, blood pressure medication, music therapy, aromatherapy and other alternative therapies. Methodological problems relate to the variability in the assessments of dementia disorders, the self-report measures and the cross-sectional data that are not definitive about directionality of predictors and effects of dementia disorders.

Young people’s happiness in the context of negative life events and coping strategies: a latent profile and latent class analysis

Young people have to cope with many negative life events and stress factors to maintain their happiness. Although there are studies on how they benefit from different coping strategies and their results, there is no study that profiles/groups young people according to negative life events and coping styles. From this point of view, the study aims to determine different life events classes and stress coping profiles in young people, and to examine the differences in happiness among the new groups created according to the discovered classes and profiles. Participants consisted of 1093 young people (M = 21.08) from different state universities in Turkey. Latent profile analysis (LPA) was conducted, resulting in a 3 profile solution characterizing coping strategies: Positive-oriented (26.8%), slightly positive-oriented (50%), and negative-oriented (23.2%) coping strategy profiles. Latent class analysis (LCA) was conducted, resulting in a 2 class solution characterizing negative life events: More negative (40.1%) and less negative (59.9%) life events classes. For the purpose of the study, the profiles created with the latent profile analysis and the latent class analysis were considered together and the participants were divided into 6 groups. These groups differed significantly in terms of happiness. The group with the highest level of happiness is the group with positive-oriented coping strategies and less negative life conditions (μ = 4.35, p < .001), and the group with the lowest level of happiness is the group with negative-oriented coping strategies and more negative life conditions (μ = 3.48, p < .001). However, the findings indicated that a positive-oriented coping strategy profile (the profile that scored high on positive coping strategies and low on negative coping strategies) offers the most promising route to happiness whether experienced negative life events are less or more.

Do yoga and meditation moderate the relationship between negative life events and depressive symptoms? Analysis of a national cross-sectional survey of Australian women.

This study aims to examine the role of yoga/meditation in the relationship between negative life events, stress and depression. The Australian Longitudinal Study on Women's Health (ALSWH) surveyed 7,186 women aged 36-43 years (mean age 39.2 years; 57.2% university degree) in 2015. Mediation and moderation analyses were conducted to examine whether yoga/meditation practice moderated those relationships. Yoga/meditation was practiced by 27.5% of participants, 33.2% reported negative life events in the past 12 months, and 24% had clinical depression. Perceived stress partially mediated the association between negative life events and depressive symptoms (B = 6.28; 95%CI 5.65; 6.92). Social support (B = -0.38; 95%CI -0.54; -0.23) and optimism (B = -0.25;95%CI -0.31; -0.18) moderated the association between stress and depressive symptoms. Yoga/meditation practice moderated the direct association between negative life events and depressive symptoms (B = -0.92; 95%CI -1.67; -0.18). Yoga/meditation use was a significant moderator of the relationship between negative life events and depression. Yoga/mediation use did not act via reducing perceived stress, but instead was found to dampen the influence of negative life events on depression directly. More research on how yoga has an impact on depression is warranted.

Negative life events and stress sensitivity in youth’s daily life: an ecological momentary assessment study

PurposeNegative life events (LEs) are associated with mental health problems in youth. However, little is known about underlying mechanisms. The aim of the study was to investigate whether exposure to LEs modifies stress sensitivity in youth’s daily life.MethodsEcological Momentary Assessment (EMA) was used to assess stress sensitivity (i.e., association of momentary stress with (i) negative affect and (ii) psychotic experiences) in 99 adolescents and young adults (42 service users, 17 siblings, and 40 controls; Mage 15 years). Before EMA, exposure to LEs (e.g., intrusive threats, experience of loss, serious illness) was assessed.ResultsLifetime as well as previous-year exposure to LEs modified stress sensitivity in service users: they experienced more intense negative affect and psychotic experiences in response to stress when high vs. low exposure levels were compared. In contrast, controls showed no differences in stress sensitivity by exposure levels. Looking at specific types of LEs, controls showed less intense negative affect in response to stress when high vs. low exposure levels to threatening events during the last year, but not lifetime exposure, were compared. In siblings, no evidence was found that LEs modified stress sensitivity.ConclusionStress sensitivity may constitute a putative risk mechanism linking LEs and mental health in help-seeking youth, while unfavourable effects of LEs on stress sensitivity may attenuate over time or do not occur in controls and siblings. Targeting individuals’ sensitivity to stress in daily life using novel digital interventions may be a promising approach towards improving youth mental health.

Validation of the German Benefit Finding Scale for Youth with chronic conditions

BackgroundBenefit finding, defined as perceiving positive life changes resulting from adversity and negative life stressors, gains growing attention in the context of chronic illness. The study aimed at examining the psychometric properties of the Benefit Finding Scale for Children (BFSC) in a sample of German youth facing chronic conditions.MethodsA sample of adolescents with various chronic conditions (N = 304; 12 – 21years) completed the 10-item BFSC along with measures of intra- and interpersonal resources, coping strategies, and health-related quality of life (hrQoL). The total sample was randomly divided into two subsamples for conducting exploratory and confirmatory factor analyses (EFA/CFA).ResultsEFA revealed that the BFSC scores had a one-dimensional factor structure. CFA verified the one-dimensional factor structure with an acceptable fit. The BFSC exhibited acceptable internal consistency (α = 0.87 – 0.88) and construct validity. In line with our hypotheses, benefit finding was positively correlated with optimism, self-esteem, self-efficacy, sense of coherence, and support seeking. There were no correlations with avoidance, wishful thinking, emotional reaction, and hrQoL. Sex differences in benefit finding were not consistent across subsamples. Benefit finding was also positively associated with age, disease severity, and social status.ConclusionsThe BFSC is a psychometrically sound instrument to assess benefit finding in adolescents with chronic illness and may facilitate further research on positive adaptation processes in adolescents, irrespective of their specific diagnosis.

Negative life stress, sleep disturbance, and depressive symptoms: The moderating role of anterior insula activity in response to sleep-related stimuli

BackgroundThis study investigated the effects of anterior insula (AI) activation on the association between stress and sleep disturbance as a neurobiological basis of the trait-like degree of sleep reactivity to stress. Additionally, it examined the effects of AI activity on the association between sleep disturbance and depression. MethodsThe participants were 48 adults. To assess AI activation in response to sleep-related stimuli (SS) compared to neutral stimuli (NS), we extracted mean AI parameter estimates for the SS–NS contrast. We examined whether the interaction between life stress and AI activation would predict sleep disturbance and whether the interaction between sleep disturbance and AI activation would predict depression. ResultsAt higher levels of bilateral AI activation in response to SS, higher levels of stress were associated with greater sleep disturbance (left AI x stress: b = 1.07, SE = 0.44, p < 0.05; right AI x stress: b = 1.05, SE = 0.48, p < 0.05). In addition, at higher levels of right AI activation, higher levels of sleep disturbance were associated with more severe depressive symptoms (right AI x sleep disturbance: b = 2.55, SE = 1.10, p < 0.05). LimitationThis study assessed sleep quality and depressive symptoms based on self-reported questionnaires. ConclusionThis study revealed moderating effects of AI activation on the association between negative life stress and sleep disturbance. Additionally, AI activation strengthened the association between sleep disturbance and depression. AI activation may reflect a crucial etiological diathesis for insomnia and stress-related disorders.

Psychological risk profile for overuse injuries in sport: An exploratory study

ABSTRACT Overuse injuries account for a substantial part of sport injury incidence among athletes of various sports and levels. Despite the gradual onset of symptoms, athletes often persevere in training and competing. The present exploratory study aimed to identify a psychological risk profile for overuse injury. One hundred and forty-nine athletes competing in various sports responded to a range of questionnaires measuring the following psychological variables: negative life stress, perfectionistic concerns, perfectionistic strivings, athletic identity, and the coach-athlete relationship. Participants subsequently answered the OSTRC Overuse Injury Questionnaire on a weekly basis during a 10-week period. Using a latent profile analysis, athletes were classified into three latent profiles regarding their psychological characteristics. Athletes in the second profile, characterized by a combination of high athletic identity, perfectionistic concerns and negative life stress and poor coach-athlete relationship, were found to be significantly more often affected by overuse injuries (74% of the time) than individuals in the two other profiles (52% and 48% of the time, respectively). In conclusion, psychological factors may contribute to the risk of overuse injuries through complex interactions (i.e. accounting for interdependencies within a specific configuration of variables) rather than through their independent influences.

Barriers and facilitators to CDH1 carriers contemplating or undergoing prophylactic total gastrectomy.

Hereditary diffuse gastric cancer (HDGC) is an inherited cancer syndrome associated with high lifetime risk of diffuse-type gastric cancer. Current guidelines recommend individuals with HDGC undergo prophylactic total gastrectomy (PTG) to eliminate this risk. However, PTG is associated with significant lifestyle changes, post-surgical recovery, and symptom burden. This study examined factors related to decision-making about PTG in three groups of individuals who: (1) underwent PTG immediately after receiving genetic testing results; (2) delayed PTG by ≥ 1year or; (3) declined PTG. Participants were recruited from a familial gastric cancer registry at a tertiary care hospital. Patients with CDH1 pathogenic or likely pathogenic variants who contemplated and/or underwent PTG were eligible. 24 individuals contemplated PTG: 9 had immediate surgery (within a year), 8 delayed surgery, and 7 declined surgery. Data on PTG barriers and facilitators were obtained on all participants using quantitative surveys (n = 7), qualitative interviews (n = 8) or both methods (n = 9). PTG barriers included age, positive beliefs about screening, close relatives with negative PTG experiences, fertility-related concerns, and life stress. Facilitators included social support, trust in healthcare providers, understanding risk, negative beliefs about screening, family-related factors, positive or abnormal screening results, and positive attitude toward PTG. This study highlights factors related to the PTG decision-making process among individuals with HDGC from three distinct groups. Future research should explore educational interventions aimed at addressing surgery-related concerns and the limitations of screening, and might also consider incorporating close relatives as informational supports.

An individual differences investigation of the relations among life event stress, working memory capacity, and mind wandering: A preregistered replication-extension study.

Klein and Boals (2001a, Applied Cognitive Psychology, 15[5], 565-579, Experiments 1 and 2) found that working memory capacity correlated negatively with perceived negative life event stress and speculated the relation may be driven by thoughts produced from these experiences. Here, we sought to replicate the association between working memory capacity and perceived negative life experience and to assess potential mediators of this association such as mind wandering propensity, rumination propensity, and the sum of negatively valenced mind wandering reports. In this preregistered replication and extension study, with data collected from 356 subjects (ns differ among analyses), we found no evidence suggesting that perceived negative life stress is associated with working memory capacity. Additionally, we found evidence consistent with the claim that negatively valenced mind wandering is uniquely detrimental to cognitive task performance, but we highlight a potential confound that may account for this association that should be addressed in future work.

THE IMPORTANCE OF EMOTIONAL CAPITAL ACROSS THE LIFESPAN: WHY THE LITTLE MOMENTS IN MARRIAGE MATTER

Throughout a marriage, couples will share countless ordinary moments together, such as laughing together or engaging in leisure activities. Although these moments may seem trivial in isolation, research suggests that accumulating small positive moments together helps couples build emotional capital, which serves as an essential resource for protecting marriages from the harmful consequences of relationship challenges. This study explored whether emotional capital may buffer couples not only from the negative effects of relational stressors, but also from the negative effects of life stressors encountered outside the relationship in a sample of younger (age 30-45) and older (age 60+) married couples. Drawing from theories of socioemotional expertise, we also examined whether the buffering effects of emotional capital may be stronger for older adults. One hundred forty-five couples completed a 21-day daily diary task assessing shared positive experiences with the partner, negative partner behaviors, marital satisfaction, life stress, and mood. Spouses who generally accrued more shared positive moments with their partner across the diary days maintained greater marital satisfaction on days of greater partner negativity compared to spouses who accrued fewer positive moments. Moreover, spouses who generally accrued more shared positive moments with their partner across the diary days also reported lower levels of negative mood on days in which they experienced more life stress compared to spouses who accrued fewer shared positive moments; in both cases, the buffering role of emotional capital was significantly stronger for older adults. All results held when adjusting for relationship length and general marital happiness.

Association between psychosocial stress and obesity among migrant and non-migrant Ghanaians

Abstract Background Psychosocial stress is associated with obesity in some populations, but it is unclear whether the association is related to migration. Aim This study explored associations between psychosocial stress and obesity among Ghanaian migrants in Europe and non-migrant Ghanaians in Ghana. Methods Cross-sectional data from the RODAM study were used, including 5898 Ghanaians residing in Germany, the UK, the Netherlands, rural Ghana, and urban Ghana. Perceived discrimination, negative life events and stress at work or at home were examined in relation to body mass index (BMI) and waist circumference (WC). Linear regression analyses were performed separately for migrants and non-migrants stratified by sex. Results Perceived discrimination was not associated with BMI and WC in both migrants and non-migrants. However, negative life events were positively associated with BMI (β = 0.78, 95% CI, 0.34 to 1.22) and WC (β = 1.96, 95% CI, 0.79 to 3.12) among male Ghanaian migrants. Among non-migrant Ghanaians, in contrast, stress at work or at home was inversely associated with BMI and WC in both males (β=-0.66, 95% CI, -1.03 to -0.28; β=-1.71 95% CI, -2.69 to -0.73, respectively) and females (β=-0.81, 95% CI, -1.20 to -0.42; β=-1.46, 95% CI, -2.30 to -0.61, respectively). Conclusions Negative life events are associated with increased body weight among Ghanaians in European settings, whereas stress at work or at home is associated with reduced body weight among Ghanaians in Ghana. More work is needed to understand the underlying factors driving these differential associations in order to assist prevention efforts. Key messages Negative life events are associated with increased body weight among Ghanaians in European settings, whereas stress at work or at home is associated with reduced body weight among Ghanaians in Ghana. More work is needed to understand the underlying factors driving these differential associations in order to assist prevention efforts.

Social support from friends predicts changes in memory specificity following a stressful life event

ABSTRACTExposure to negative life stress has been associated with difficulty retrieving memories for specific autobiographical events, with important consequences for the emergence of emotional disorders. We examined whether social support can protect against the effects of negative events on memory specificity. University students (N = 143) were assigned to groups based on whether or not they experienced a negative stressor, operationalised as whether or not their recent exam performance was in line with their expectations. After receiving their exam results (T1), and one month later (T2), participants completed measures of memory specificity, their attitudes towards themselves and the occurrence of other stress-related events. Participants also completed a general measure of perceived social support from friends, family, and significant others, and an equivalent measure for social support related to performance. For participants who experienced an exam-related stressor, reduced performance-specific social support from friends was associated with reduced memory specificity at T2, even when accounting for T1 memory specificity, individual differences in attitudes towards self, the experience of additional stressors, and gender. No such relation was present for participants who did not experience a stressor. These findings provide new understanding of the influence of social variables on autobiographical memory specificity.

Differential associations between psychosocial stress and obesity among Ghanaians in Europe and in Ghana: findings from the RODAM study

Similarly, stress at work or at home was positively associated with BMI (β = 0.28, 95% CI 0.00–0.56) and WC (β = 0.84, 95% CI 0.05–1.63) among male Ghanaian migrants. Among non-migrant Ghanaians, in contrast, stress at work or at home was inversely associated with BMI and WC in both males (β = − 0.66, 95% CI − 1.03 to − 0.28; β = − 1.71 95% CI − 2.69 to − 0.73, respectively) and females (β = − 0.81, 95% CI − 1.20 to − 0.42; β = − 1.46, 95% CI − 2.30 to − 0.61, respectively).ConclusionsNegative life events and stress at work or at home are associated with increased body weight among male Ghanaians in European settings, whereas stress at work or at home is associated with reduced body weight among Ghanaians in Ghana.

Affective Forecasting Bias: Liability or Protective Factor?

We examined whether affective forecasting biases prospectively predict depression and anxiety symptoms in the context of life stress. Participants (n = 72) completed- baseline measures of depression, anxiety, and mood predictions, followed by one week of ecological momentary assessments of mood. Three months later, they completed measures of depression, anxiety, and life stress. Neither positive nor negative mood prediction biases at baseline were associated with follow-up anxiety scores. Positive mood prediction biases were not associated with follow-up depression scores. However, the interaction between negative mood prediction bias and life stress predicted follow-up depression scores. Under conditions of greater life stress, stronger negative mood prediction biases predicted lower follow-up depression scores. Under conditions of positive life change, stronger negative mood prediction biases predicted higher follow-up depression scores. Negative mood prediction bias might serve as a protective or liability factor, depending on levels of stress. Clinical implications and future directions are discussed.

Risk factors for challenging behaviour and psychopathology in adults with Down syndrome.

This study explored the role of demographic, psychosocial, stress and life event-related risk factors for psychopathology and challenging behaviour in a clinical sample of adults with Down syndrome. A convenience sample of adults with Down syndrome seen through a specialised clinic was assessed through interviews and questionnaires specifically designed for use in people with intellectual disabilities. Recent negative life events and stressors were significantly correlated with mental and behavioural health, and significantly predicted irritability, lethargy and depressed mood. Social avoidance was predicted by stress related to anticipation and social-environmental stressors, and negatively predicted by verbal ability. Ritual-related stress predicted obsessive-compulsive behaviour. Participants who did not have a job or vocational placement were significantly more depressed than participants who did. Adults with Down syndrome should be provided increased supports for coping with negative life events and stressors. Interventions should also emphasise community engagement, such as employment, and access to psychosocial supports that teach coping and self-regulation skills when faced with stressors and negative life events.

Inter-Relationships Among Cultural Identity, Discrimination, Distress, Agency, and Safety Among Indigenous People in Custody

ABSTRACTA strong cultural identity has been shown to protect against psychological distress prompted by discriminatory experiences. However, these associations are scientifically unknown for people who have contact with the criminal justice system. Examining the relationships between cultural identity and mental health could enlighten efforts to improve the wellbeing of offenders, many of whom have experienced numerous negative life events and stressors. This study aimed to address these concerns by assessing the influence of cultural identity on distress, agency, community safety and discrimination for 78 Indigenous prisoners in custody in Australia. Findings revealed that possessing a stronger cultural identity effected lower levels of distress. Participants with weaker cultural identities had higher levels of distress and lower levels of agency. Furthermore, a reduced feeling of safety in the broader community appeared to have a greater negative impact on participants with weaker cultural identities. Levels of distress increased as perceptions of discrimination increased, immaterial to one's degree of cultural identity. However, results suggest that high identifiers were potentially able to alleviate this distress, perhaps through enhanced agency and engagement in cultural activities. Findings underscore the need for forensic clinicians to consider notions of cultural identity when engaging with, assessing and treating Indigenous clients.

Associations of Positive Affect and Negative Affect With Allostatic Load: A Lifelines Cohort Study.

Allostatic load (AL) reflects the deteriorating influences of stress on the body and comprises a selection of biological markers. AL is associated with negative life events, stress, and negative affect (NA), as well as poor health outcomes. However, whether AL is also associated with positive affect (PA) is not clear. The present study therefore explores the association between PA and AL, accounting for age, sex, NA, and health behaviors. Data of 45,225 individuals from the first wave of the multidisciplinary prospective population-based cohort study Lifelines were used. AL was operationalized as the sum of 12 inflammatory, cardiovascular, and metabolic markers. The association between PA and AL was tested in a cross-sectional study design using multiple linear regression analysis, adjusting for NA, confounders, and health behaviors. In addition, we explored whether the relation was moderated by age, sex, and NA. The AL profile was inversely associated with PA (B = -0.083, p < .001) when adjusted for NA, age, and sex. The association between AL and PA remained significant after adjusting for health behaviors (B = -0.076, p < .001). A significant moderating effect was found for sex (PA by sex: B = 0.046, p = .001), indicating that the association between PA and AL was stronger in women than in men. PA was associated with a more favorable AL profile, especially in women. These results add to the evidence that PA might be of relevance to the etiology of disease.

Stress and reward processing in bipolar disorder: a functional magnetic resonance imaging study.

A link between negative life stress and the onset of mood episodes in bipolar disorder (BD) has been established, but processes underlying such a link remain unclear. Growing evidence suggests that stress can negatively affect reward processing and related neurobiological substrates, indicating that a dysregulated reward system may provide a partial explanation. The aim of this study was to test the impact of stress on reward-related neural functioning in BD. Thirteen euthymic or mildly depressed individuals with BD and 15 controls performed a Monetary Incentive Delay (MID) task while undergoing functional magnetic resonance imaging during no-stress and stress (negative psychosocial stressor involving poor performance feedback and threat of monetary deductions) conditions. In hypothesis-driven region-of-interest analyses, a significant group-by-condition interaction emerged in the amygdala during reward anticipation. Relative to controls, while anticipating a potential reward, subjects with BD were characterized by amygdalar hyperactivation in the no-stress condition but hypoactivation during stress. Moreover, relative to controls, subjects with BD had significantly larger amygdala volumes. After controlling for structural differences, the effects of stress on amygdalar function remained, whereas groups no longer differed during the no-stress condition. During reward consumption, a group-by-condition interaction emerged in the putamen due to increased putamen activation in response to rewards in participants with BD during stress, but an opposite pattern in controls. Overall, findings highlight possible impairments in using reward-predicting cues to adaptively engage in goal-directed actions in BD, combined with stress-induced hypersensitivity to reward consumption. Potential clinical implications are discussed.

Understanding the Stress Process of Chinese- and Korean-American Breast Cancer Survivors.

Guided by the stress process model (SPM), this study investigated the direct and indirect pathways of primary (negative self-image and life stress), secondary stressors (family communication strain) and family coping (external and internal) on mental health outcomes among Chinese- and Korean-American breast cancer survivors (BCS). A total of 156 Chinese- and Korean-American BCS were surveyed. Results showed primary and secondary stressors had a negative effect on better mental health outcomes. External coping was associated with better mental health. Family communication strain mediated the relationship between life stress and mental health outcomes. External coping mediated the relationship between family communication strain and mental health outcomes. Multi-group analysis revealed the stress process did not differ across ethnic groups. Findings suggest the SPM may be applicable to understand the stress process of Chinese- and Korean-American BCS and provide valuable insight into the role of family communication and external coping on mental health outcomes.

PROTOCOL: Predictors of youth gang membership in low‐ and middle‐income countries: A systematic review

BACKGROUND The Problem There is evidence of gang violence in low- and middle-income countries in Africa and Asia, and the prevalence of gangs is particularly well documented throughout Central and South America (Decker & Pyrooz, 2010; Gatti et al., 2011). Official estimates of gang membership in Central America estimate approximately 69,000 members, while academic estimates believe this figure to be closer to 200,000 (UNODC, 2007). Some estimates are as high as 500,000 gang members in the region including South America and the Caribbean, and gangs have been identified as “the primary threat to regional stability and security” (Muggah & Aguirre, 2013). While reporting and recording issues make it difficult to estimate rates of gang violence, the homicide rate in Colombia, Brazil, El Salvador and Guatemala are substantially higher than those of European and North American countries (Decker & Pyrooz, 2010; UNODC, 2007). Gangs are also active in South Africa, with an estimate of 100,000 members in Western Cape alone (Reckson & Becker, cited in Decker & Pyrooz, 2010); however, to date, there is limited research examining gangs in Africa and Asia...
