Self-compassion is related to psychological well-being and can improve mental health problems. The present study aimed to examine the relationship of self-compassion with anxiety and depression symptoms considering the mediating effects of shame and guilt. Two hundred forty-three participants in Iran completed the measures of Depression, Anxiety, Stress Scale (DASS), self-compassion Scale-Short Form (SCS-SF), and personal feelings questionnaire-2 (PFQ-2 Brief). The result showed that there was a significant negative correlation between self-compassion and shame, guilt, depression, and anxiety. The correlation between shame and guilt with depression and anxiety was also positive and significant. Mediation analysis was used to examine whether self-compassion predicted decreased symptoms of depression and anxiety through decreased shame and guilt. The results showed that self-compassion has a negative direct effect on depression symptoms. The direct effect of self-compassion on anxiety symptoms was not significant. Moreover, we found that shame and guilt mediate the relationship between self-compassion and depressive symptoms. However, the indirect effect of guilt on anxiety symptoms was not significant. The findings of the current study demonstrate that Self-compassion is linked to more psychological strengths and efficient emotional regulations, leading to less self-conscious emotions (shame and guilt) and decreased depression and anxiety symptoms.

This study aimed to characterize the network structure of pandemic grief symptoms and suicidal ideation in 2174 people from eight Latin American countries. Pandemic grief and suicidal ideation were measured using the Pandemic Grief Scale and a single item, respectively. Network analysis provides an in-depth characterization of symptom-symptom interactions within mental disorders. The results indicated that, "desire to die," "apathy" and "absence of sense of life" are the most central symptoms in a pandemic grief symptom network; therefore, these symptoms could be focal elements for preventive and treatment efforts. Suicidal ideation, the wish to die, and the absence of meaning in life had the strongest relationship. In general, the network structure did not differ among the participating countries. It identifies specific symptoms within the network that may increase the likelihood of their co-occurrence and is useful at the therapeutic level.

This study examined whether employee stances of hostile attribution, perceived hostile climate, attitudes toward aggression, subjective norms, and perceived control affected workplace aggression and victimization in departments of social services. We also explored differences in workplace aggression and victimization in social services in Israel and compared departments of social services of mixed and nonmixed cities (Arabs and Jews). A sample of 470 social workers employed by social services in Israel completed self-report measures. We used regression analysis to explore levels of aggression and victimization in general and specifically within social services departments in both mixed and nonmixed cities. We also investigated the differences in workplace aggression and victimization between these departments. Stances related to both aggression and victimization were perceived control and perceived hostile climate. No statistically significant differences were found in aggression or victimization levels between mixed and nonmixed cities. However, the relationship between hostile climate and victimization was found to be weaker in mixed cities than in nonmixed cities, suggesting a more complex interaction of organizational climate in different urban contexts. This study shed light on similar stances between aggression and victimization and explicated the phenomenon of workplace aggression using two important aspects of aggression and victimization. Furthermore, the study revealed important differences in victimization patterns between mixed and nonmixed cities' social services departments, particularly regarding the role of hostile climate in these different settings.

The results from clinical trials have indicated that the tau aggregation inhibitor hydromethylthionine mesylate (HMTM) produces disease-modifying effects in Alzheimer's disease (AD) patients when administered alone, but less of an effect when administered in conjunction with cholinesterase inhibitors (ChEIs). The use of ChEIs for AD has been supported by their ability to reverse scopolamine-induced cognitive impairments in rodents reminiscent of those seen in AD patients. We have previously shown that another tau aggregation inhibitor, methylthionine chloride (MTC), is able to reverse scopolamine-induced deficits in spatial learning and memory. The objective here was to determine the symptomatic efficacy of HMTM and rivastigmine, alone or in combination, in a scopolamine model of AD. Female NMRI mice were treated systemically with scopolamine (0.5 mg/kg) or vehicle in combination with ChEI rivastigmine (0.5 mg/kg) or HMTM (5 or 15 mg/kg) daily before assessment of spatial learning and memory performance in a reference memory task in the water maze. Systemic administration of scopolamine induced significant impairments in the spatial learning of the mice compared to vehicle treatment. These deficits were reversed by treatment with HMTM at both doses and with rivastigmine when given alone. Furthermore, coadministration of rivastigmine with HMTM ameliorated the impairments induced by scopolamine. These findings extend our previous observations with MTC and confirm that HMTM also has a dual mode of action, disease modification through tau aggregation inhibition, but also having symptomatic effects through its normalisation of cholinergic activity.

Older adults often exhibit reduced performance in visual search tasks and more exploitation in foraging tasks. Target-distractor similarity-a common difficulty manipulation in visual search-can offer insight into age-related differences in visual attention and foraging strategies. However, this manipulation has rarely been assessed with categorical information or been implemented in foraging tasks, which could enhance the ecological validity of such paradigms. This study investigated age-related differences in a foraging task using a categorical target-distractor similarity manipulation. Younger adults (aged 18-35 years, n = 65) and older adults (aged 55-80 years, n = 66) without cognitive impairment completed an online foraging task, where they searched for multiple target objects belonging to a specific category (e.g., "bed") among distractors from either high similarity categories (e.g., "furniture") or low similarity categories (e.g., "clothes"). Older participants were generally slower, collected fewer targets, and showed less search efficiency in the high similarity condition. However, both age groups demonstrated similar foraging strategies, showing slightly more exploitation in the high similarity condition. Target-distractor similarity appeared to increase demands on attentional control, especially for older participants. Nonetheless, exploration-exploitation behavior was less affected, suggesting that older participants attempted to mitigate the cognitive demands of target-distractor similarity by strategies such as collecting fewer targets. These findings indicate age-related differences in categorical search and highlight how older adults can adapt to increased cognitive control demands to maintain optimal foraging behavior.

Subjective age-the age people feel-fluctuates considerably across days and even within days. We investigated how subjective age fluctuations are intertwined with experiences of momentary pain and how the within-person couplings of subjective age and pain are shaped by long-term changes in physical health using data from 139 older individuals participating in the Berlin Aging Study II (age 67-88, 41.3% women). After providing long-term longitudinal data across on average 7 years on central facets of physical health (pain severity, pain interference, chronic diseases) study participants completed repeated daily-life assessments of subjective age and pain up to six times per day across one full week. Results from dynamic structural equation models that combine latent change score models with location scale models of intraindividual variability indicate that in moments when individuals report pain that is 10 points above their overall average pain (on a scale from 0 = no pain to 100 = most intense pain), they feel a third of a year older than their average subjective age. Individuals who experienced steeper long-term 7-year increases in both pain severity and pain interference exhibited a stronger subjective age reactivity to momentary pain (i.e., within-person couplings of elevated momentary pain with an older subjective age) and greater subjective age systemic noise (i.e., nonpain-related momentary fluctuations in subjective age). Our findings suggest that moment-to-moment fluctuations in older adults' subjective age in daily life are shaped both by moment-to-moment fluctuations in pain and cumulative long-term physical health trajectories.

Social media offers numerous advantages, yet the dark side of it haunts youth. One of the several potential detrimental aspects appears as social media addiction (SmA), which poses risks to the psychological well-being (PW) of youth. Among university students, excessive social media use can lead to SmA and a subsequent decrease in PW. This study scrutinizes the mediating effects of techno-invasion (TI) and techno-overload (TO), instigated by SmA, on students' psychological well-being, a relationship that previous research has not conclusively explored. Our research constructs a model to examine the moderating effects of social capital, specifically through the lenses of social bonding and social bridging, on the nexus between social media-induced challenges and psychological well-being. This investigation examines the associations between SmA, TO and TI through self-esteem among students. Data collected through a three-wave time-lagged design from 991 university students in Abu Dhabi, UAE, were analyzed with the PROCESS macro. The findings reveal that SmA is significantly negatively related to students' self-esteem, which in turn is associated with increased levels of TI and TO, ultimately reducing psychological well-being. Moreover, the study verifies the moderating roles of social bonding and social bridging in the TI-PW and TO-PW relationships. The paper concludes by addressing the broader implications of these findings and suggesting avenues for future research in this domain. This study demonstrates how SmA reduces self-esteem, which in turn increases TO and TI, ultimately leading to a decline in PW. The findings suggest that improving self-esteem and enhancing social capital through stronger connections with family and friends can help alleviate the negative consequences of SmA on students' well-being, offering valuable contributions to the literature on digital stress and mental health.

Negative emotional stimuli are associated with increased recognition accuracy but decreased memory for the associative context, an effect coined as "tunnel memory" (Steinmetz & Kensinger, 2013). Recently, Stewardson et al. (2023) found that social cues enhance both recognition and associative memory and weaken the effects of negative emotion on memory, suggesting potentially distinct mechanisms underlying how adaptively relevant information is processed and retained when social cues are present. In this study (conducted in 2023-2024), we sought to replicate these findings and use eye tracking to explore attention as a mechanism underlying this divergence. As predicted, both negative images and social cues enhanced recognition memory, with differential effects on associative memory (diminishing for negative, enhancing for social). Negative pictures with few social cues were associated with a "tunneling" of both memory and attention, that is, better recognition but poorer associative memory alongside more frequent, longer fixations on the picture and reduced picture-object saccades. By contrast, social cues led to a partial tunneling of attention-that is, more frequent but shorter fixations and fewer linking saccades-and yet enhanced both picture recognition and associative memory. Perhaps most striking, negative emotion's effects on memory and attention were significantly attenuated when social cues were present. These findings suggest that differences in how negative versus neutral content is processed and retained depend on the social context. (PsycInfo Database Record (c) 2026 APA, all rights reserved).

Child maltreatment has been linked to numerous psychopathology outcomes throughout life, with emotion regulation proposed as a transdiagnostic mechanism. However, it remains relatively unknown how childhood abuse and neglect may differentially predict the development of emotion regulation during later years vulnerable to psychopathology. We examined the impact of early abuse and neglect experiences on the developmental trajectories of emotion regulation throughout adolescence and into young adulthood. The sample consisted of 167 adolescents who completed questionnaires assessing emotion regulation difficulties and emotion regulation strategies (cognitive reappraisal and expressive suppression) approximately annually across six time points, from ages 14 to 20 (2014-2021). Information on maltreatment experienced from ages 1 to 13 was collected at 18-19 years. Conditional growth curve models examining the effects of both abuse and neglect from ages 1 to 13 on the initial levels and growth rates of emotion regulation difficulties and strategies from ages 14 to 20. Abuse predicted developmental changes in emotion regulation difficulties, such that greater childhood abuse was associated with larger increases in emotion regulation difficulties from ages 14 to 20. Neglect predicted the initial levels of emotion regulation difficulties such that greater childhood neglect was associated with greater difficulties in emotion regulation at age 14. The findings suggest developmental consequences of childhood abuse and neglect evidenced by impaired development of emotion regulation abilities throughout adolescence and into young adulthood, whereas emotion regulation strategy is relatively unaffected by childhood abuse and neglect.
