Using Mindfulness- and Acceptance-Based Treatments With Clients From Nondominant Cultural and/or Marginalized Backgrounds: Clinical Considerations,Meta-Analysis Findings,and Introduction to the Special Series: Clinical Considerations in using Acceptance- and Mindfulness-based Treatments With Diverse Populations

A growing body of research suggests that mindfulness- and acceptance-based principles can increase efforts aimed at reducing human suffering and increasing quality of life. A critical step in the development and evaluation of these new approaches to treatment is to determine the acceptability and efficacy of these treatments for clients from nondominant cultural and/or marginalized backgrounds. This special series brings together the wisdom of clinicians and researchers who are currently engaged in clinical practice and treatment research with populations who are historically underrepresented in the treatment literature. As an introduction to the series, this paper presents a theoretical background and research context for the papers in the series, highlights the elements of mindfulness- and acceptance-based treatments that may be congruent with culturally responsive treatment, and briefly outlines the general principles of cultural competence and responsive treatment. Additionally, the results of a meta-analysis of mindfulness- and acceptance-based treatments with clients from nondominant cultural and/or marginalized backgrounds are presented. Our search yielded 32 studies totaling 2,198 clients. Results suggest small (Hedges' g = .38, 95% CI = .11 – .64) to large (Hedges' g = 1.32, 95% CI = .61 – 2.02) effect sizes for mindfulness- and acceptance-based treatments, which varied by study design.     

Women’s Reporting of Physical Assaults to Police in a National Sample: A Brief Report

Research examining reporting decisions of women physically assaulted by any type of perpetrator is scarce. This study used data from the National Violence Against Women Survey (NVAWS) to examine how victim characteristics, assault characteristics, emotions during the assault, and postassault disclosure to informal social support sources affect victim and third-party reporting decisions in physical assault incidents. Results showed that victim education, race and ethnicity, victim–offender relationship, crime severity, perceived life threat, and disclosure to informal social support sources were related to victim reporting, whereas victim employment and marital status were associated with third-party reporting.     

Sticking to the Evidence? A Behavioral and Computational Case Study of Micro‐Theory Change in the Domain of Magnetism

Constructing an intuitive theory from data confronts learners with a “chicken‐and‐egg” problem: The laws can only be expressed in terms of the theory's core concepts, but these concepts are only meaningful in terms of the role they play in the theory's laws; how can a learner discover appropriate concepts and laws simultaneously, knowing neither to begin with? We explore how children can solve this chicken‐and‐egg problem in the domain of magnetism, drawing on perspectives from computational modeling and behavioral experiments. We present 4‐ and 5‐year‐olds with two different simplified magnet‐learning tasks. Children appropriately constrain their beliefs to two hypotheses following ambiguous but informative evidence. Following a critical intervention, they learn the correct theory. In the second study, children infer the correct number of categories given no information about the possible causal laws. Children's hypotheses in these tasks are explained as rational inferences within a Bayesian computational framework.     

CD4 Count and Physical Symptoms Among Urban African American Mothers with HIV: An Examination of the Role of Optimism and Depressive Symptoms

The current study examined the link between immune functioning (CD4 count) and physical symptoms, as well as the moderating role of optimism and depressive symptoms, in a sample of 99 low income, inner city African American women with HIV. Although there was no main effect of CD4 count on physical symptoms, depressive symptoms moderated the association between CD4 count and physical symptoms. More compromised immune functioning (lower CD4 count) was associated with more physical symptoms under conditions of higher levels of depressive symptoms, but not lower levels of depressive symptoms. This finding was observed using both a self-report measure and a clinician-rating of women’s depressive symptoms. There were no main or interactive effects for optimism. Clinical implications and future research directions are presented.     

Emotional content of true and false memories

Many people believe that emotional memories (including those that arise in therapy) are particularly likely to represent true events because of their emotional content. But is emotional content a reliable indicator of memory accuracy? The current research assessed the emotional content of participants' pre-existing (true) and manipulated (false) memories for childhood events. False memories for one of three emotional childhood events were planted using a suggestive manipulation and then compared, along several subjective dimensions, with other participants' true memories. On most emotional dimensions (e.g., how emotional was this event for you?), true and false memories were indistinguishable. On a few measures (e.g., intensity of feelings at the time of the event), true memories were more emotional than false memories in the aggregate, yet true and false memories were equally likely to be rated as uniformly emotional. These results suggest that even substantial emotional content may not reliably indicate memory accuracy.     

The persistence of false beliefs

Do false beliefs last? To explore this question, this study planted false beliefs or memories of a childhood experience with asparagus. We found that these false beliefs had consequences for subjects, when assessed directly after the suggestive manipulation. Moreover, subjects were brought back two weeks later to see if their false beliefs persisted. After two weeks, subjects' confidence in their new memories, and the consequences of those memories were diminished, but not extinguished. These false beliefs were found to be somewhat weaker than other subjects' true beliefs for the same events. Another novel finding was that the manipulation was sufficiently powerful to affect actual food choices.
