Article Synopsis
  • The study examined how adverse childhood experiences (ACEs) and shared religious/spiritual practices affect relationship satisfaction among 374 distressed couples seeking therapy.
  • Males' ACEs negatively impacted both their and their partners' satisfaction, while females' ACEs only affected their own satisfaction.
  • Shared religious/spiritual practices positively influenced satisfaction, but only for females; also, relationship satisfaction changes were more significant in the early therapy sessions and then tapered off over time.

We investigated insecure attachment in relation to how actively romantic partners expect to participate in couple therapy (role expectations for self and partner) and, consequently, how much they expect to benefit from doing so (outcome expectations). Specifically, we used the mediated actor-partner interdependence model (Ledermann et al., 2011) with archived data from 297 heterosexual couples in a research-practice network (L.

The global impact of the SARS-COV-2 pandemic necessitated a rapid shift to online/teletherapy psychotherapy services. While research suggests the feasibility and efficacy of teletherapy, there is limited investigation into couple teletherapy's impact on satisfaction and therapeutic alliance. This study aimed to address this gap by examining changes in couple satisfaction during tele- and in-person therapy sessions over 12 sessions and exploring whether therapeutic alliance development mediates these changes.

Monitoring the therapeutic alliance throughout treatment can improve client outcomes and lead to improved care. The individual, couple, and family versions of the intersession alliance measure (IAM) were developed to facilitate routine monitoring of the expanded therapeutic alliance. Psychometric properties of the three versions of the IAM were examined using a clinical sample.

As chronic wasting disease (CWD) continues to spread across North America, the relationship between CWD and host genetics has become of interest. In Rocky Mountain elk (Cervus elaphus nelsoni), one or two copies of a leucine allele at codon 132 of the prion protein gene (132L*) has been shown to prolong the incubation period of CWD. Our study examined the relationship between CWD epidemiology and codon 132 evolution in elk from Wyoming, USA, from 2011 to 2018.

Two recent studies of eye closure triggered by intense luminance increase suggest that this behavior reflects the melanopsin-based retinal activity known to underlie photophobia, the pathological aversion to light (Kardon, 2012; Kaiser et al., 2021). Early studies of the photic blink reflex (PBR) are reviewed to help guide future research on this possible objective index of photophobia.

Hepatitis C virus (HCV) infection can have serious consequences when untreated and diagnosis is the first step in any treatment regimen. In the Unites States a 2-step algorithm consisting of HCV antibody screening and HCV RNA testing of HCV antibody-reactive specimens is recommended for detection of current HCV infection. We conducted a survey of HCV diagnostic practices in US public health laboratories and convened a meeting of HCV subject matter experts to identify opportunities for improvement in HCV diagnosis.

Recent efforts to improve marital therapy interventions have begun investigating psychophysiologic processes in therapy. These studies are novel and represent initial investigations into relevant phenomena associated with the therapy process. Grounded in Polyvagal Theory, this study introduces an on-going multimethod couple therapy process research (CHAMPS) and highlights the importance of establishing norms among distressed couples in therapy, which can provide context for other studies' results and instigate further investigation of physiology in marital therapy.

Despite the pivotal role that emotion regulation is thought to occupy for individual and relational wellbeing, emotion regulation in couples has been surprisingly understudied. With a clinical sample consisting of 275 couples starting therapy from 2017 to 2022, this study sought to clarify the actor and partner effects of clinical couples' emotion dysregulation on relationship satisfaction. Our results showed that, for partners' emotion dysregulation dimensions, while impulse control difficulties, lack of emotional awareness, and limited emotion regulation strategies were negatively predictive of couple relationship satisfaction, nonacceptance of negative emotions had a positive association with relationship satisfaction.

The Systemic Clinical Outcome and Routine Evaluation version 15 (SCORE-15) is a measure used to assess family-level change in family therapy. The SCORE-15 has been demonstrated to be a reliable and valid measure, with high clinical utility; however, the SCORE-15 lacks the ability to determine whether the change in family functioning during the course of therapy is clinically significant. This study aimed to establish a reliable change index (RCI) and clinical cutoff score so that researchers and clinicians can determine clinically significant change in family therapy.

The duodenum can be affected by a variety of abnormalities because of its development during embryogenesis and its dual intra- and retroperitoneal location. If small bowel embryogenesis is disturbed, congenital errors occur. Although some congenital variants may be asymptomatic and inconsequential to the patient, other anomalies can result in life-threatening emergencies such as malrotation, leading to midgut volvulus.

Infectious diseases play an important role in wildlife population dynamics by altering individual fitness, but detecting disease-driven natural selection in free-ranging populations is difficult due to complex disease-host relationships. Chronic wasting disease (CWD) is a fatal infectious prion disease in cervids for which mutations in a single gene have been mechanistically linked to disease outcomes, providing a rare opportunity to study disease-driven selection in wildlife. In Wyoming, USA, CWD has gradually spread across mule deer () populations, producing natural variation in disease history to evaluate selection pressure.

Background: Noninvasive and cuffless approaches to monitor blood pressure (BP), in light of their convenience and accuracy, have paved the way toward remote screening and management of hypertension. However, existing noninvasive methodologies, which operate on mechanical, electrical, and optical sensing modalities, have not been thoroughly evaluated in demographically and racially diverse populations. Thus, the potential accuracy of these technologies in populations where they could have the greatest impact has not been sufficiently addressed.

Routine outcome monitoring (ROM) is an important component of evidence-based practice. To implement ROM in their practice, couple therapists need a brief measure that can quickly assess the relevant aspects of a couple's relationship. The Couple Relationship Scale (CRS) is a 10-item measure of relational functioning that assesses emotional intimacy, commitment, trust, safety, cohesion, acceptance, conflict, physical intimacy, overall happiness, and personal well-being.

Article Synopsis
  • Invasive species often carry limited genetic diversity from their native populations due to factors like founder events, which can affect their ability to adapt and thrive in new environments.
  • The study analyzes the genetic diversity of the invasive termite species Reticulitermes flavipes, comparing data from native and introduced populations across the globe to understand its invasion history.
  • Findings indicate a complex invasion process featuring numerous introduction events, with substantial gene flow likely facilitated by human activity, suggesting that increased genetic diversity in both native and introduced ranges may enhance invasion success.

Background: The standard in vivo diagnostic imaging technique for cerebral amyloid angiopathy (CAA) is costly and thereby of limited utility for point-of-care diagnosis and monitoring of treatment efficacy. Recent recognition that retinal changes may reflect cerebral changes in neurodegenerative disease provides an ideal opportunity for development of accessible and cost-effective biomarkers for point-of-care use in the detection and monitoring of CAA. In this pilot study, we examined structural and angiographic retinal changes in CAA patients relative to a control group, and compared retinal and cerebral pathology in a group of CAA patients.

Marriage and family therapy scholars have argued that therapists play a crucial role in successful couple therapy, yet little research has empirically documented that the therapist in couple therapy has a significant impact on outcomes. Known as the study of therapist effects, this study sought to assess the amount of variance attributed to the therapist in couple therapy outcomes. Using dropout as the outcome variable, this study analyzed data from 1,192 couples treated by 90 masters and doctoral student therapists at a university-based training clinic.

Bayesian modeling is becoming increasing popular as a method for data analyses in the social sciences and can move couple, marriage, and family therapy (C/MFT) research forward. Bayesian modeling helps researchers better understand the uncertainty of findings and incorporate previous research into analyses. Other benefits of Bayesian modeling are the straightforward interpretation of findings, high-quality inferences even with small samples (in combination with an informative prior), and the ability to work with complex data structures (observations nested in relationships and time points) which are common in C/MFT research.

African Americans, compared with all other racial/ethnic groups, are more likely to contract coronavirus disease 2019 (COVID-19), be hospitalized for it, and die of the disease. Psychosocial, sociocultural, and environmental vulnerabilities, compounded by preexisting health conditions, exacerbate this health disparity. Interconnected historical, policy, clinical, and community factors explain and underpin community-based participatory research approaches to advance the art and science of community engagement among African Americans in the COVID-19 era.
