Efficacy of a Workbook to Promote Forgiveness: A Randomized Controlled Trial with University Students

Objective The present study investigated the efficacy of a 6-hour self-directed workbook adapted from the REACH Forgiveness intervention. Method Undergraduates (N = 41) were randomly assigned to either an immediate treatment or waitlist control condition. Participants were assessed across 3 time periods using a variety of forgiveness outcome measures. Results The 6-hour workbook intervention increased forgiveness, as indicated by positive changes in participants’ forgiveness ratings that differed by condition. In addition, benchmarking analysis showed that the self-directed workbook intervention is at least as efficacious as the delivery of the REACH Forgiveness model via group therapy. Conclusion A self-directed workbook intervention adapted from the REACH Forgiveness intervention provides an adjunct to traditional psychotherapy that could assist the mental health community to manage the burden of unforgiveness among victims of interpersonal harm

Efficacy of REACH Forgiveness across Cultures

Across cultures, most people agree that forgiveness is a virtue. However, culture may influence how willing one should be to forgive and how one might express forgiveness. At a university in the United States, we recruited both foreign-extraction students and domestic students (N = 102) to participate in a six-hour REACH Forgiveness intervention. We investigated the efficacy of the intervention overall as well as whether foreign-extraction and domestic students responded differently to treatment. Forgiveness was assessed using two measures—decisional forgiveness and emotional forgiveness. The six-hour REACH Forgiveness intervention improved participants’ ratings of emotional forgiveness, but not decisional forgiveness, regardless of their culture. Thus, the REACH Forgiveness intervention appears equally efficacious for participants from different cultural backgrounds when conducted in the United States with college students

Forgiveness of In-group Offenders in Christian Congregations

Religious communities, like other communities, are ripe for interpersonal offenses. We examined the degree to which group identification predicted forgiveness of an in-group offender. We examined the effects of a victim’s perception of his or her religious group identification as a state-specific personal variable on forgiveness by integrating Social Identity Theory into a model of Relational Spirituality (Davis, Hook, & Worthington, 2008) to help explain victim’s responses to transgressions within a religious context. Data were collected from members of Christian congregations from the mid-west region of the United States (Study 1, N = 63), and college students belonging to Christian congregations (Study 2, N = 376). Regression analyses demonstrated that even after statistically controlling for many religious and transgression-related variables, group identification with a congregation still predicted variance in revenge and benevolence toward an in-group offender after a transgression. Additionally, mediation analyses suggest group identification as one mechanism through which trait forgivingness relates to forgiveness of specific offenses. We discuss the importance of group identity in forgiving other in-group members in a religious community

Genetic mechanisms of critical illness in COVID-19.

Host-mediated lung inflammation is present1, and drives mortality2, in the critical illness caused by coronavirus disease 2019 (COVID-19). Host genetic variants associated with critical illness may identify mechanistic targets for therapeutic development3. Here we report the results of the GenOMICC (Genetics Of Mortality In Critical Care) genome-wide association study in 2,244 critically ill patients with COVID-19 from 208 UK intensive care units. We have identified and replicated the following new genome-wide significant associations: on chromosome 12q24.13 (rs10735079, P = 1.65 × 10-8) in a gene cluster that encodes antiviral restriction enzyme activators (OAS1, OAS2 and OAS3); on chromosome 19p13.2 (rs74956615, P = 2.3 × 10-8) near the gene that encodes tyrosine kinase 2 (TYK2); on chromosome 19p13.3 (rs2109069, P = 3.98 ×  10-12) within the gene that encodes dipeptidyl peptidase 9 (DPP9); and on chromosome 21q22.1 (rs2236757, P = 4.99 × 10-8) in the interferon receptor gene IFNAR2. We identified potential targets for repurposing of licensed medications: using Mendelian randomization, we found evidence that low expression of IFNAR2, or high expression of TYK2, are associated with life-threatening disease; and transcriptome-wide association in lung tissue revealed that high expression of the monocyte-macrophage chemotactic receptor CCR2 is associated with severe COVID-19. Our results identify robust genetic signals relating to key host antiviral defence mechanisms and mediators of inflammatory organ damage in COVID-19. Both mechanisms may be amenable to targeted treatment with existing drugs. However, large-scale randomized clinical trials will be essential before any change to clinical practice

The (not so) controversial role of DNA methylation in epigenetic inheritance across generations.

It has been demonstrated originally in plants that phenotypic traits, such as floral symmetry, can be caused by changes of methylation patterns of specific genes. Such traits can be transgenerationally inherited for multiple generations and remain associated with cytosine methylation patterns. Whether genomic methylation may also contribute to epigenetic inheritance across generations in vertebrates and notably in mammals is still more controversial. One reason for this tentativeness is the dual occurrence of global genomic de-methylation first in pre-implantation embryos and subsequently in primordial germ cells (PGCs) of mammals. Although gene focused cases of epigenetic inheritance associated with genomic DNA methylation have been well studied mostly in rodents (such as imprinted genes and the Agouti viable yellow, Avy, allele), it is still a matter of debate whether genomic DNA methylation may provide a more general mechanism for the epigenetic inheritance of acquired traits across generations. We review the current literature on this topic with a focus on the potential role of DNA methylation for epigenetic inheritance across generations in mammals
