Acculturative Stress and Latino Depression: The Mediating Role of Behavioral and Cognitive Resources

Although research has found that acculturative stress is significantly associated with adverse psychological adjustment among Latinos, the mechanism by which this relationship exists is not clearly understood. The purpose of this study was to investigate the role of behavioral and cognitive resources—active coping and self-efficacy, respectively—as mediators of the relationship between acculturative stress and depression among a sample of Latina/o adults (N = 469). Multiple mediator analysis indicated that active coping partially mediated the relationship between acculturative stress and depression symptom severity. The indirect relationship of acculturative stress to depression symptom severity through self-efficacy was not significant. The results suggest that acculturative stress directly relates to Latino psychological adjustment, and lower behavioral active coping partially accounts for this relationship. Results are discussed in the context of culturally based stress and coping models, wherein the relationship between stressors and subsequent psychological adjustment is influenced by the degree of fit between stressor demands and individuals’ resources. Implications for treatment and theory are discussed

Discrimination, Acculturation, Acculturative Stress, and Latino Psychological Distress: A Moderated-Mediational Model

Prior research has found that perceived discrimination is associated with adverse mental health outcomes among Latinos. However, the process by which this relationship occurs remains an understudied area. The present study investigated the role of acculturative stress in underlying the relationship between perceived discrimination and Latino psychological distress. Also examined was the ability of acculturation to serve as a moderator between perceived discrimination and acculturative stress. Among a sample of Latino adults (N = 669), moderated mediational analyses revealed that acculturative stress mediated the perceived discrimination-psychological distress relationship, and that the link between perceived discrimination and acculturative stress was moderated by Anglo behavioral orientation but not Latino behavioral orientation. The findings are discussed within a stress and coping perspective that identifies the psychological consequences associated with perceived discrimination and acculturative stress

Microaggressions and Psychological Functioning among High Achieving African-Americans: A Mixed-Methods Approach

Racial microaggressions and their influence on mental health were examined among African American doctoral students and graduates of doctoral programs. Using a mixed-methods approach, the current study first identified the types of microaggressions reported by African American participants (N = 97) and then investigated the mechanism by which these experiences influence mental health over time with a separate sample of African Americans (N = 107). The qualitative findings revealed three categories of microaggressions including Assumption of Criminality/Second-Class Citizen, Underestimation of Personal Ability, and Cultural/racial Isolation. The quantitative analyses found support for a moderated-mediational model by which Underestimation of Personal Ability was associated with greater perceived stress at one-year follow-up, which in turn was related to greater depressive symptoms. Active coping was found to moderate the racial microaggression-perceived stress link such that individuals who endorse active coping behaviors reported lower perceived stress. These findings are discussed in terms of practical and theoretical implications regarding the role of racial micro-aggressions in the lives of high-achieving African Americans and the mechanisms by which these experiences contribute to mental health problems

Validation of the Implementation Climate Scale (ICS) in substance use disorder treatment organizations.

BackgroundOne critical factor in the implementation of evidence-based practice (EBP) in substance use disorder treatment organizations is an inner organizational context that clearly supports implementation efforts. The Implementation Climate Scale (ICS) has been developed to allow researchers and organizations to assess climate for EBP implementation in health and allied health service organizations. The ICS consists of 18 items and measures six dimensions of implementation climate: focus on EBP, educational support for EBP, recognition for EBP, rewards for EBP, selection for EBP, and selection for openness. The ICS was initially developed in a mental health context; thus, the goal of this study was to provide initial validation of the ICS in substance use disorder (SUD) treatment settings.MethodsConfirmatory factor analysis (CFA) was used to assess the psychometric functioning of the ICS using survey data from 326 providers in 65 teams in SUD treatment programs. Cronbach's alpha was examined to assess internal consistency of the ICS, and individual and team level construct-based validity was examined by comparing its correlations with service climate, molar climate, and organizational change.ResultsWe found evidence for the reliability, factor structure, and validity of the ICS in SUD services. The psychometric functioning of the ICS in SUD treatment settings was comparable to that found in mental health contexts.ConclusionsThe ICS is a brief and pragmatic tool for researchers to better understand a critical antecedent for implementation effectiveness in SUD treatment and for organizational leaders in SUD treatment organizations to evaluate the extent to which providers perceive that their organization supports EBP implementation

Low-Cost Oil Quality Sensor Based on Changes in Complex Permittivity

Real time oil quality monitoring techniques help to protect important industry assets, minimize downtime and reduce maintenance costs. The measurement of a lubricant’s complex permittivity is an effective indicator of the oil degradation process and it can be useful in condition based maintenance (CBM) to select the most adequate oil replacement maintenance schedules. A discussion of the working principles of an oil quality sensor based on a marginal oscillator to monitor the losses of the dielectric at high frequencies (>1 MHz) is presented. An electronic design procedure is covered which results in a low cost, effective and ruggedized sensor implementation suitable for use in harsh environments

The Protective Roles of Latinx Intercultural Competence and Acculturation on Acculturative Stress and Depression: A Brief Longitudinal Study

This study examined the ability of cognitive schemas of culturally based skills, or Latinx intercultural competence (LIC), and acculturation to influence later acculturative stress and depression symptom severity. Latinx adults (final n 98), recruited from national e-mail listings and organizations with a predominant Latinx cultural base, completed online self-report measures of Latinx and Anglo acculturation, acculturative stress, LIC, and depression symptom severity at baseline (T1) and 6-month follow-up (T2). Path analysis indicated that T1 LIC was significantly related to greater T1 Latinx and T1 Anglo acculturation, and that T1 LIC was significantly, indirectly related to lower T2 acculturative stress through greater T1 Latinx acculturation. Greater T1 Latinx acculturation, but not T1 Anglo acculturation, was significantly, indirectly related to lower T2 depression through lower T2 acculturative stress. For Latinx adults, LIC may guide the expression of culturally sanctioned behavior through greater Latinx and Anglo acculturation. Heritage-culture acculturation may be crucial in protecting against later acculturative stress and depression. Findings are discussed in the context of the person-environment fit for effective intercultural exchange, and the potential importance of strengthening ties to cultural heritage in promoting Latinx mental health

Long-term storage and age‐biased export of fluvial organic carbon: field evidence from West Iceland

Terrestrial organic carbon (OC) plays an important role in the carbon cycle, but questions remain regarding the controls and timescale(s) over which atmospheric CO₂ remains sequestered as particulate OC (POC). Motivated by observations that terrestrial POC is physically stored within soils and other shallow sedimentary deposits, we examined the role that sediment storage plays in the terrestrial OC cycle. Specifically, we tested the hypothesis that sediment storage impacts the age of terrestrial POC. We focused on the Efri Haukadalsá River catchment in Iceland as it lacks ancient sedimentary bedrock that would otherwise bias radiocarbon‐based determinations of POC storage duration by supplying pre‐aged “petrogenic” POC. Our radiocarbon measurements of riverine suspended sediments and deposits implicated millennial‐scale storage times. Comparison between the sample types (suspended and deposits) suggested an age offset between transported (suspended sediments) and stored (deposits) POC at the time of sampling, which is predicted by theory for the sediment age distribution in floodplains. We also observed that POC in suspended sediments is younger than the predicted mean storage duration generated from independent geomorphological data, which suggested an additional role for OC cycling. Consistent with this, we observed interparticle heterogeneity in the composition of POC by imaging our samples at the microscale using X‐ray absorption spectroscopy. Specifically, we found that particles within individual samples differed in their sulfur oxidation state, which is indicative of multiple origins and/or diagenetic histories. Altogether, our results support recent coupled sediment storage and OC cycling models and indicate that the physical drivers of sediment storage are important factors controlling the cadence of carbon cycling

Mindfulness Meditation Activates Altruism.

Clinical evidence suggests that mindfulness meditation reduces anxiety, depression, and stress, and improves emotion regulation due to modulation of activity in neural substrates linked to the regulation of emotions and social preferences. However, less was known about whether mindfulness meditation might alter pro-social behavior. Here we examined whether mindfulness meditation activates human altruism, a component of social cooperation. Using a simple donation game, which is a real-world version of the Dictator's Game, we randomly assigned 326 subjects to a mindfulness meditation online session or control and measured their willingness to donate a portion of their payment for participation as a charitable donation. Subjects who underwent the meditation treatment donated at a 2.61 times higher rate than the control (p = 0.005), after controlling for socio-demographics. We also found a larger treatment effect of meditation among those who did not go to college (p < 0.001) and those who were under 25 years of age (p < 0.001), with both subject groups contributing virtually nothing in the control condition. Our results imply high context modularity of human altruism and the development of intervention approaches including mindfulness meditation to increase social cooperation, especially among subjects with low baseline willingness to contribute
