RESUMEN

Background: The current study examined the role of avoidance in behavioral activation treatment compared to a supportive counseling condition targeting depressive symptoms in a sample comprised of Latinx individuals. Method: Depressed Latinx individuals with Spanish-speaking preference (LSSP; N = 46) were randomized to receive 10-weekly sessions of Brief Behavioral Activation Treatment for Depression (BATD) or supportive counseling. Participants completed weekly self-report measures of depressive symptoms and avoidance. Results: Avoidance levels decreased over the course of both treatments. However, decreases in depressive symptoms were associated with decreases in avoidance over time only for individuals who were randomized to BATD. Greater change in avoidance levels was related to post-treatment depression score, only for those who received BATD. Finally, greater avoidance prior to commencing treatment predicted lower depressive symptom change over the course of both treatments. Conclusions: This study provides preliminary evidence that avoidance may be a specific proposed mechanism of depression change in BATD among LSSP with depression. Pretreatment avoidance appears to be a useful construct to identify the trajectories of depressive symptoms over the course of psychotherapy among LSSP.

RESUMEN

The objective of this study was to examine the accuracy of indexing for "Appalachian Region"[Mesh]. Researchers performed a search in PubMed for articles published in 2019 using "Appalachian Region"[Mesh] or "Appalachia" or "Appalachian" in the title or abstract. Only 17.88% of the articles retrieved by the search were about Appalachia according to the ARC definition. Most articles retrieved appeared because they were indexed with state terms that were included as part of the mesh term. Database indexing and searching transparency is of growing importance as indexers rely increasingly on automated systems to catalog information and publications.

RESUMEN

Past research supports the role of negative posttraumatic cognitions (NPCs) in the development and maintenance of posttraumatic stress disorder (PTSD). The relationship between NPCs and PTSD may be uniquely impacted by racial status and experiences of military sexual trauma (MST), both of which may have a unique impact on one's understanding of self, others, and the world. We explored racial differences in the association between NPCs and PTSD symptom clusters in a sample of veterans endorsing MST (N = 139; 74.8% White, 25.2% Black). A path model was created and analyzed both with the full sample and separately by racial group. In the full sample, NPCs about the self and world were significantly associated with intrusion, negative alterations in cognitions and mood (NACM), and arousal, but not avoidance. Self-blame was not a significant predictor of negative alterations in cognition in mood. This model was consistent in the White veteran model, whereas only negative cognitions about the self were associated with NACM in the Black veteran path model. NPCs about the self and world appear important to non-avoidance PTSD symptomatology related to MST and thus should be targeted in treatment. For Black veterans endorsing distress related to NACM symptoms, negative beliefs about the self should be specifically considered for intervention.

RESUMEN

Black Americans living in urban environments are disproportionately impacted by posttraumatic stress disorder (PTSD). Both racial discrimination and neighborhood poverty are factors that contribute to this health disparity. However, studies focused on the intersection of these two oppressive systems on PTSD symptoms are lacking. To address this gap in the literature, we assessed the interactive effects of racial discrimination and neighborhood poverty on PTSD symptoms in an urban sample of trauma-exposed Black women (N = 300). Simple moderation analysis was used to assess the main and interactive effects of racial discrimination and neighborhood poverty on PTSD symptoms. The overall model significantly predicted PTSD symptoms, with a main effect of racial discrimination (B = 1.87, p = .009) and neighborhood poverty rate (B = 0.29, p = .008), independent of prior trauma exposure and percentage of Black residents in the zip code. More frequent experiences of racial discrimination and higher rates of neighborhood poverty both predicted higher PTSD symptoms. There was also a trending interaction of racial discrimination and neighborhood poverty (B = -0.05, p = .054), where the effect of neighborhood poverty on PTSD symptoms was only present for those who reported fewer experiences of racial discrimination. Our results suggest that people who have experienced more instances of racial discrimination show high levels of PTSD symptoms regardless of neighborhood poverty rates and highlight the importance of considering multiple levels of oppression that Black individuals face while diagnosing and treating stress-related psychopathology.

RESUMEN

Protic ruthenium complexes using the dihydroxybipyridine (dhbp) ligand combined with a spectator ligand (N,N = bpy, phen, dop, Bphen) have been studied for their potential activity vs. cancer cells and their photophysical luminescent properties. These complexes vary in the extent of π expansion and the use of proximal (6,6'-dhbp) or distal (4,4'-dhbp) hydroxy groups. Eight complexes are studied herein as the acidic (OH bearing) form, [(N,N)2Ru(n,n'-dhbp)]Cl2, or as the doubly deprotonated (O- bearing) form. Thus, the presence of these two protonation states gives 16 complexes that have been isolated and studied. Complex 7A, [(dop)2Ru(4,4'-dhbp)]Cl2, has been recently synthesized and characterized spectroscopically and by X-ray crystallography. The deprotonated forms of three complexes are also reported herein for the first time. The other complexes studied have been synthesized previously. Three complexes are light-activated and exhibit photocytotoxicity. The log(Do/w) values of the complexes are used herein to correlate photocytotoxicity with improved cellular uptake. For Ru complexes 1-4 bearing the 6,6'-dhbp ligand, photoluminescence studies (all in deaerated acetonitrile) have revealed that steric strain leads to photodissociation which tends to reduce photoluminescent lifetimes and quantum yields in both protonation states. For Ru complexes 5-8 bearing the 4,4'-dhbp ligand, the deprotonated Ru complexes (5B-8B) have low photoluminescent lifetimes and quantum yields due to quenching that is proposed to involve the 3LLCT excited state and charge transfer from the [O2-bpy]2- ligand to the N,N spectator ligand. The protonated OH bearing 4,4'-dhbp Ru complexes (5A-8A) have long luminescence lifetimes which increase with increasing π expansion on the N,N spectator ligand. The Bphen complex, 8A, has the longest lifetime of the series at 3.45 µs and a photoluminescence quantum yield of 18.7%. This Ru complex also exhibits the best photocytotoxicity of the series. A long luminescence lifetime is correlated with greater singlet oxygen quantum yields because the triplet excited state is presumably long-lived enough to interact with 3O2 to yield 1O2.

RESUMEN

Nine ruthenium CNC pincer complexes (1-9) were tested for anticancer activity in cell culture under both dark and light conditions. These complexes included varied CNC pincer ligands including OH, OMe, or Me substituents on the pyridyl ring and wingtip N-heterocyclic carbene (NHC) groups which varied as methyl (Me), phenyl (Ph), mesityl (Mes), and 2,6-diisopropylphenyl (Dipp). The supporting ligands included acetonitrile, Cl, and 2,2'-bipyridine (bpy) donors. The synthesis of complexes 8 and 9 is described herein and are fully characterized by spectroscopic (1H NMR, IR, UV-Vis, MS) and analytical techniques. Single crystal X-ray diffraction results are reported herein for 8 and 9. The other complexes (1-7) are reported elsewhere. The four most lipophilic ruthenium complexes (6, 7, 8, and 9) showed the best activity vs. MCF7 cancer cells with complexes 6 and 9 showing cytotoxicity and complex 7 and 8 showing light activated photocytotoxicity. The distribution of these compounds between octanol and water is reported as log(Do/w) values, and increasing log(Do/w) values correlate roughly with improved activity vs. cancer cells. Overall, lipophilic wingtip groups (e.g. Ph, Mes, Dipp) on the NHC ring and a lower cationic charge (1+ vs. 2+) appears to be beneficial for improved anticancer activity.

RESUMEN

Dominant group members often are not aware of the privileges they benefit from due to their dominant group membership. Yet individuals are members of multiple groups and may simultaneously occupy multiple categories of dominance and marginality, raising the question of how different group memberships work in concert to facilitate or inhibit awareness of multiple forms of privilege. Examining awareness of privilege is important as awareness may be linked to action to dismantle systems of privilege that maintain oppression and inequality. Grounded in intersectional scholarship, in this study we examined how occupying intersecting categories of race/ethnicity, gender, and religion corresponded to an awareness of White, male, and Christian privilege. In a sample of 2321 Midwestern college students, we demonstrated that students from marginalized groups broadly reported greater awareness of all forms of privilege than students from dominant groups, and the difference between marginalized and dominant groups was most pronounced when the specific group category (e.g., gender) aligned with the type of privilege (e.g., male privilege). We also tested interactions among race/ethnicity, gender, and religion, only finding an interaction between race/ethnicity and religion for awareness of White and male privilege. These findings helped to clarify that multiple group memberships tended to contribute to awareness as multiple main effects rather than as multiplicative. Finally, we examined mean differences among the eight intersected groups to explore similarities and differences among groups in awareness of all types of privilege. Taken together, these findings quantitatively demonstrate the ways in which group memberships work together to contribute to awareness of multiple forms of privilege. We discuss study limitations and implications for community psychology research and practice.

RESUMEN

Scholars in the field of community psychology have called for more research dedicated to examining White privilege as part of a system of White supremacy in the United States. One branch of this work focuses on awareness of White privilege, yet to date, this research has typically investigated awareness of White privilege at individual levels of analysis instead of also focusing on neighborhoods, schools, and other levels of analysis beyond the individual. In this study, we combine survey and U.S. Census data to explore both individual- and community-level predictors of White privilege awareness. With a sample of 1285 White college students, we found that gender, modern racism, social dominance orientation, and subjective socioeconomic status (SES) significantly predicted White privilege awareness. After accounting for these individual-level variables, we found that characteristics of students' hometowns (defined by zip code) predicted White privilege awareness. Specifically, greater income inequality was associated with higher White privilege awareness, while greater White racial homogeneity was marginally associated with lower White privilege awareness. There was a significant interaction between community-level White racial homogeneity and individual-level subjective SES, such that students with high subjective SES and low White racial homogeneity had the highest White privilege awareness. This study highlights the importance of examining different facets of ecological context in relation to White Americans' racial attitudes.

RESUMEN

Scholars have proposed 2 separable dimensions of racial colorblind ideology: the first is centered on "not seeing color" (i.e., color evasion), and the second is centered on denying racism (i.e., power evasion). Yet, to date, there is no psychometric evidence for this distinction. In this article, we aim to fill this gap by establishing the presence of and characterizing differences between these 2 dimensions using both variable-centered and person-centered approaches. Study 1A (n = 707) provides exploratory factor analytic evidence supporting the separability of power and color evasion. Study 1B (n = 710) provides confirmatory evidence of this factor structure and evidence of discriminant validity. In Study 1B, 3 latent profiles based on power and color evasion were identified: acknowledgers (low color evasion, low power evasion), evaders (high color evasion, average power evasion), and deniers (average color evasion, average power evasion), which differed on relevant variables (e.g., modern racism, support for affirmative-action). In Study 2 (n = 546), these profiles were replicated and extended by examining differences in attitudes and desire to engage in campus diversity activities. Implications for racial colorblind ideology theory and practical applications are discussed. (PsycInfo Database Record (c) 2020 APA, all rights reserved).

RESUMEN

Although significant strides have been made for sexual and gender minority (SGM) rights in the United States, there continues to be opposition to SGM rights from many conservative Christians and political conservatives. In this study, we investigate this opposition by examining support for Christian hegemony (i.e., the idea that Christianity should be the norm and Christians should be in power in the United States) and unawareness of Christian privilege (i.e., unearned advantages for Christians) as religiopolitical variables that help to explain the association between Christian and political conservatism and opposition to a host of SGM rights (same-sex marriage, same-sex adoption, nondiscrimination policies in jobs and housing for SGMs, and bills regarding transgender public bathroom use). Based on structural equation modeling analysis with heterosexual cisgender Christian (n = 688) and Areligious (n = 327) students, we demonstrate that support for Christian hegemony and unawareness of Christian privilege help to explain the association between Christian and political conservatism and opposition to SGM rights. These findings advance our understanding of a new type of religious-based variable focused on religious power and privilege to help understand conservative religious and political opposition to SGM rights. Limitations, implications, and directions for future research also are discussed.

RESUMEN

Religious congregations are social settings where people gather together in community to pursue the sacred (Pargament, 2008). Such settings are important to understand as they provide a context for individuals to develop relationships, share ideas and resources, and connect individuals to larger society (Todd, 2017a). Yet, research to date has not deeply examined the inherently relational nature of religious congregations. Thus, in this study, we used social settings theory (Seidman, 2012; Tseng & Seidman, 2007) to develop and test hypotheses about relationships within one Christian religious congregation. In particular, we used social network analysis to test hypotheses about relational activity, popularity, and homophily for friendship and spiritual support types of relational links. Our findings demonstrate how relational patterns may be linked to participation in congregational activities, occupying a leadership role, a sense of community and spiritual satisfaction, stratification, socialization, and spiritual support. Overall, this advances theory and research on the relational aspects of religious congregations, and more broadly to the literature on social settings. Limitations, directions for future research, and implications for theory and religious congregations also are discussed.
