Culture and Quality Matter in Building Effective Mentorship Relationships with Native STEM Scholars.

Native peoples (Native American, Alaskan Native, Native Hawaiian) are underrepresented in academia; they represent 2% of the US population but 0.01% of enrolled undergraduate students. Native peoples share the experiences of colonization and forced assimilation, resulting in the loss of ancestral knowledge, language, and cultural identity. Recognizing history and the literature on social integration and mentorship, we followed 100 Native science and engineering scholars across a year of participation in the hybrid American Indian Science and Engineering Society mentorship program. The results showed that high-quality faculty mentorship predicted persistence a year later. Furthermore, mentors who shared knowledge of Native culture-through experience or shared heritage-uniquely contributed to the Native scholars' social integration and persistence through scientific community values in particular. Therefore, Native scholars may benefit from mentorship supporting the integration of their Native culture and discipline rather than assimilation into the dominant disciplinary culture.

Emotion regulation choice: a broad examination of external factors.

Emotion regulation choices are known to be profoundly consequential across affective, cognitive, and social domains. Prior studies have identified two important external factors of emotion regulation choice: stimulus intensity and reappraisal affordances. However, whether there are other external factors of emotion regulation choice and how these factors contribute to emotion regulation choice when considered simultaneously is not yet clear. The current studies addressed these gaps by examining the relations between emotion regulation choice (distraction vs. reappraisal) and self-reported stimulus intensity, reappraisal affordances, and several other factors including discrete emotions and distraction affordances. Across three studies using different databases of standardised images to enhance generalizability, our results showed that in the context of our experiments, reappraisal affordances were strongly associated with emotion regulation choice (greater reappraisal affordances predicted higher use of reappraisal). Further, stimulus intensity was independently associated with emotion regulation choice in each study. Our results also demonstrated that the discrete emotion of disgust (but not other discrete emotions) is a previously unidentified external factor of emotion regulation choice. We discuss the implications of the current findings.

Emotion regulation choice: the role of environmental affordances.

Which emotion regulation strategy one uses in a given context can have profound affective, cognitive, and social consequences. It is therefore important to understand the determinants of emotion regulation choice. Many prior studies have examined person-specific, internal determinants of emotion regulation choice. Recently, it has become clear that external variables that are properties of the stimulus can also influence emotion regulation choice. In the present research, we consider whether reappraisal affordances, defined as the opportunities for re-interpretation of a stimulus that are inherent in that stimulus, can shape individuals' emotion regulation choices. We show that reappraisal affordances have stability across people and across time (Study 1), and are confounded with emotional intensity for a standardised set of picture stimuli (Study 2). Since emotional intensity has been shown to drive emotion regulation choice, we construct a context in which emotional intensity is separable from reappraisal affordances (Study 3) and use this context to show that reappraisal affordances powerfully influence emotion regulation choice even when emotional intensity and discrete emotions are taken into account (Study 4).

Focusing the APA Ethics Code to Include Development: Applications to Abuse.

Extant ethics codes in psychological work generally are not sufficiently developmentally oriented. Here, we examine the American Psychological Association ethics code for its developmental sensitivity, find it lacking in this regard, and make recommendations. Our approach was to place children and youth at the forefront in forming developmentally-targeted principles, meta-principles, values, and rights. To further this aim, we consulted the one ethics code in the field that is developmentally-attuned, the ethics code of the American Academy of Child and Adolescent Psychiatry. We used a revised set of ethical principles for psychological work and developed a set of meta-principles. The five APA ethics code principles are: (a) beneficence and nonmaleficence; (b) fidelity and responsibility; (c) integrity; (d) justice; and (e) respect for people's rights and dignity. The set of ethical principles taken from Young (Revising the American Psychological Association ethics code, Springer International Publishing, 2017) includes: (a) life preservation, (b) caring beneficence/nonmaleficence, (c) relational integrity, (d) respect for the dignity and rights of persons and peoples, and (e) promoting and acting from justice in society. The major meta-principles proposed here include: (a) functioning from responsibility, (b) promoting personhood, and (c) promoting participation. In addition, we added meta-principles for working from appropriate (d) theory and (e) meta-theory (Neo-Maslovian and a combined relationism-empiricism, respectively). Secondary meta-principles in the text refer to (a) systems, (b) the person as unique, (c) the vulnerabilities of people, (d) autonomy, and (e) morality.

Judging emotions as good or bad: Individual differences and associations with psychological health.

People differ in their initial emotional responses to events, and we are beginning to understand these responses and their pervasive implications for psychological health. However, people also differ in how they think about and react to their initial emotions (i.e., emotion judgments). In turn, how people judge their emotions-as predominantly positive or negative-may have crucial implications for psychological health. Across five MTurk and undergraduate samples collected between 2017 and 2022 (total N = 1,647), we investigated the nature of habitual emotion judgments (Aim 1) and their associations with psychological health (Aim 2). In Aim 1, we found four distinct habitual emotion judgments that differ according to the valence of the judgment (positive or negative) and the valence of the emotion being judged (positive or negative). Individual differences in habitual emotion judgments were moderately stable across time and were associated with, but not redundant with, conceptually related constructs (e.g., affect valuation, emotion preferences, stress mindsets, meta-emotions) and broader traits (i.e., extraversion, neuroticism, trait emotions). In Aim 2, positive judgments of positive emotions were uniquely associated with better psychological health and negative judgments of negative emotions were uniquely associated with worse psychological health concurrently and prospectively, above and beyond the other types of emotion judgments, and above and beyond conceptually related constructs and broader traits. This research gives insight into how people judge their emotions, how these judgments relate to other emotion-related constructs, and their implications for psychological health.

In vitro antimicrobial studies of silver carbene complexes: activity of free and nanoparticle carbene formulations against clinical isolates of pathogenic bacteria.

OBJECTIVES: Silver carbenes may represent novel, broad-spectrum antimicrobial agents that have low toxicity while providing varying chemistry for targeted applications. Here, the bactericidal activity of four silver carbene complexes (SCCs) with different formulations, including nanoparticles (NPs) and micelles, was tested against a panel of clinical strains of bacteria and fungi that are the causative agents of many skin and soft tissue, respiratory, wound, blood, and nosocomial infections. METHODS: MIC, MBC and multidose experiments were conducted against a broad range of bacteria and fungi. Time-release and cytotoxicity studies of the compounds were also carried out. Free SCCs and SCC NPs were tested against a panel of medically important pathogens, including methicillin-resistant Staphylococcus aureus (MRSA), multidrug-resistant Acinetobacter baumannii (MRAB), Pseudomonas aeruginosa, Burkholderia cepacia and Klebsiella pneumoniae. RESULTS: All four SCCs demonstrated strong efficacy in concentration ranges of 0.5-90 mg/L. Clinical bacterial isolates with high inherent resistance to purified compounds were more effectively treated either with an NP formulation of these compounds or by repeated dosing. Overall, the compounds were active against highly resistant bacterial strains, such as MRSA and MRAB, and were active against the biodefence pathogens Bacillus anthracis and Yersinia pestis. All of the medically important bacterial strains tested play a role in many different infectious diseases. CONCLUSIONS: The four SCCs described here, including their development as NP therapies, show great promise for treating a wide variety of bacterial and fungal pathogens that are not easily killed by routine antimicrobial agents.

Development of the Pseudomonas aeruginosa mushroom morphology and cavity formation by iron-starvation: a mathematical modeling study.

We present a mathematical model of mushroom-like architecture and cavity formation in Pseudomonas aeruginosa biofilms. We demonstrate that a proposed disparity in internal friction between the stalk and cap extracellular polymeric substances (EPS) leads to spatial variation in volumetric expansion sufficient to produce the mushroom morphology. The capability of diffusible signals to induce the formation of a fluid-filled cavity within the cap is then investigated. We assume that conversion of bacteria to the planktonic state within the cap occurs in response to the accumulation or depletion of some signal molecule. We (a) show that neither simple nutrient starvation nor signal production by one or more subpopulations of bacteria is sufficient to trigger localized cavity formation. We then (b) demonstrate various hypothetical scenarios that could result in localized cavity formation. Finally, we (c) model iron availability as a detachment signal and show simulation results demonstrating cavity formation by iron starvation. We conclude that iron availability is a plausible mechanism by which fluid-filled cavities form in the cap region of mushroom-like structures.

Psychotherapeutic Change Mechanisms and Causal Psychotherapy: Applications to Child Abuse and Trauma.

The study of change mechanisms in psychotherapy needs to be integrated with the causality of behavior, which leads to the concept of causal psychotherapy. Causal psychotherapy is posited as a useful adjunct to standard, evidence based psychotherapies for child and youth victims of abuse and trauma. The article illustrates six processes that could be involved in causal psychotherapy in this context, from the distal to the proximal. They include the distal mechanism of activation-inhibition coordination. The most proximal one relates to executive function. The intermediate levels include ones related to co-regulation (e.g., self control), analysis-synthesis, objectivity-subjectivity, and psychological reserve, which is a new concept in the domain of psychological change mechanisms. Each of the variables can vary from high to low, with the low end being more problematic. Psychotherapy can aim to bring the patient toward adaptive levels. The literature review focuses on psychotherapeutic change mechanisms, and standard psychotherapies for child/youth abuse/trauma, especially trauma-focused cognitive behavior therapy (TF-CBT). Then, it considers causal aspects of child/youth abuse and trauma, including PTSD. The discussion relates causal therapy to the question of unifying psychology and psychotherapy under the rubric of causality as a core integrative mechanism.

Interpreting symptom validity test fails in forensic disability and related assessments: When the cry for help for one fail makes sense.

Dandachi-FitzGerald et al. (2022), published the article "Cry for help as a root cause of poor symptom validity: A critical note," in Applied Neuropsychology: Adult [Advance Online], arguing that the cry for help in forensic disability and related assessments is not a valid interpretation for poor symptom validity test results. This rebuttal contests the criticisms of the use of the cry for help in this context, as presented in Young (2019); "The Cry for help in a psychological injury and law: Concepts and review" that appeared in Psychological Injury and Law, Vol. 12, pp. 225-237. It calls for more programmatic research, for example, based on the cry for help questionnaire suggested by the author. In particular, it indicates, for example, that one SVT test failure in a test battery constitutes an assessment result that could allow for attributing the cry for help, everything else being equal. It suggests that the adaptational theory explains the cry for help as much as malingering. It suggests practice and court recommendations that will allow better rebuttals of unethical assessors who overuse/misuse/abuse the cry for help interpretation of poor symptom validity test results in forensic disability and related assessments.

Prospective associations between emotion regulation and depressive symptoms among Mexican-origin adolescents.

Reappraisal (reconstruing emotional experiences to alter their impact) and suppression (inhibiting emotionally expressive behavior) are emotion-regulation strategies with important implications for depression. While reappraisal generally predicts lower depressive symptoms, suppression generally predicts higher depressive symptoms. Because cultural factors can influence the processes involved in these links and because adolescence-especially for ethnic minority youth-brings particular emotional challenges, it's critical to investigate these links among Mexican-origin adolescents. However, research examining emotion regulation among Mexican-origin individuals is scarce and generally limited to cross-sectional designs. Thus, we examined prospective associations between reappraisal and suppression (assessed at age 17) and 2 facets of depressive symptoms (anhedonia and general distress) over 3 years (assessed at ages 16, 18, and 19) among 228 Mexican-origin adolescents. Latent growth curve models indicated that reappraisal was associated with lower anhedonia at baseline (age 16) and lower anhedonia over time, whereas suppression predicted greater anhedonia at baseline but not change over time. Consistent with the Mexican cultural value of simpatía, which emphasizes expressing positive emotions and inhibiting negative emotions, suppression of positive emotions was associated with greater anhedonia over time whereas suppression of negative emotions was associated with lower anhedonia over time. However, neither associated with anhedonia at baseline. Reappraisal and suppression were not associated with distress symptoms, and no effects were moderated by familism, household income, gender, or child nativity. The anhedonia results suggest that the benefits of reappraisal extend to Mexican-origin adolescents, but the effects of suppression may depend upon emotional valence in this group.

Content and Quality of Science Training Programs Matter: Longitudinal Study of the Biology Scholars Program.

Many science training programs are successful at supporting students in completing their degree programs. However, it is not clear which aspects of these programs meaningfully contribute toward achieving this goal. The current longitudinal study examined a well-established science training program, the Biology Scholars Program (BSP) at the University of California, Berkeley, to see whether social connections formed in BSP and/or enthusiasm about the BSP activities are key components in contributing to students' greater integration into their professional communities at 12 months and intentions to persist at 18 months into the program. Results indicated social connections and program enthusiasm at 6 months were unassociated with science efficacy, identity, and community values. However, social connections and program enthusiasm at 12 months were generally associated with higher levels of all these variables, with science identity and community values uniquely related to greater integration. Together, results show that students' connection to faculty, staff, and peers and enthusiasm for the program activities are both key components of successful, multiyear science training programs. Our results also suggest that, while connections and enthusiasm might develop quickly, their downstream consequences might only be observed after students build stronger social relations and enthusiasm for program activities in ways that foster greater integration.

Comparability and Validity of the Online and In-Person Administrations of the Inventory of Problems-29.

While the psychometric equivalence of computerized versus paper-and-pencil administration formats has been documented for some tests, so far very few studies have focused on the comparability and validity of test scores obtained via in-person versus remote administrations, and none of them have researched a symptom validity test (SVT). To contribute to fill this gap in the literature, we investigated the scores of the Inventory of Problems-29 (IOP-29) generated by various administration formats. More specifically, Study 1 evaluated the equivalence of scores from nonclinical individuals administered the IOP-29 remotely (n = 146) versus in-person via computer (n = 140) versus in-person via paper-and-pencil format (n = 140). Study 2 reviewed published IOP-29 studies conducted using remote/online versus in-person, paper-and-pencil test administrations to determine if remote testing could adversely influence the validity of IOP-29 test results. Taken together, our findings suggest that the effectiveness of the IOP-29 is preserved when alternating between face-to-face and online/remote formats.

Affective Benefits of Nature Contact: The Role of Rumination.

Mounting evidence shows that nature contact is associated with affective benefits. However, the psychological mechanisms responsible for these effects are not well understood. In this study, we examined whether more time spent in nature was associated with higher levels of positive affect in general, and lower levels of negative affect and rumination in general. We also conducted a cross-sectional mediation analysis to examine whether rumination mediated the association of nature contact with affect. Participants (N = 617) reported their average time spent in nature each week, as well as their general levels of positive and negative affect, and the degree to which they typically engaged in rumination in daily life. We then used structural equation modeling to test our hypotheses. Our results support the hypothesis that nature contact is associated with general levels of affect, and that rumination mediates this association for negative affect, and marginally mediates this association for positive affect.

Civil Forensic Evaluation in Psychological Injury and Law: Legal, Professional, and Ethical Considerations.

Psychologists who work as therapists or administrators, or who engage in forensic practice in criminal justice settings, find it daunting to transition into practice in civil cases involving personal injury, namely psychological injury from the psychological perspective. In civil cases, psychological injury arises from allegedly deliberate or negligent acts of the defendant(s) that the plaintiff contends caused psychological conditions to appear. These alleged acts are disputed in courts and other tribunals. Conditions considered in psychological injury cases include posttraumatic stress disorder, depression, chronic pain conditions, and sequelae of traumatic brain injury. This article outlines a detailed case sequence from referral through the end of expert testimony to guide the practitioner to work effectively in this field of practice. It addresses the rules and regulations that govern admissibility of expert evidence in court. The article provides ethical and professional guidance throughout, including best practices in assessment and testing, and emphasizes evidence-based forensic practice.

The Influence of Microaffirmations on Undergraduate Persistence in Science Career Pathways.

The present studies aimed to advance the measurement and understanding of microaffirmation kindness cues and assessed how they related to historically underrepresented (HU) and historically overrepresented (HO) undergraduate student persistence in science-related career pathways. Study 1 developed and tested the dimensionality of a new Microaffirmations Scale. Study 2 confirmed the two-factor structure of the Microaffirmations Scale and demonstrated that the scale possessed measurement invariance across HU and HO students. Further, the scale was administered as part of a longitudinal design spanning 9 months, with results showing that students' reported microaffirmations did not directly predict higher intentions to persist in science-related career pathways 9 months later. However, scientific self-efficacy and identity, measures of student integration into the science community, mediated this relationship. Overall, our results demonstrated that microaffirmations can be measured in an academic context and that these experiences have predictive value when they increase students' integration into their science communities, ultimately resulting in greater intentions to persist 9 months later. Researchers and practitioners can use the Microaffirmations Scale for future investigations to increase understanding of the positive contextual factors that can ultimately help reduce persistence gaps in science, technology, engineering, and mathematics degree attainment.

An investigation into the drivers of avolition in schizophrenia.

Over a century of research has documented that avolition is a core symptom in schizophrenia. However, the drivers of avolition remain unclear. Conceptually, there are at least two potential mutually compatible drivers that could cause avolition in schizophrenia. First, people with schizophrenia might have differences in preferences that result in less goal-directed behavior than non-clinical populations (preference-differences). Second, people with schizophrenia might have difficulty translating their preferences into manifest behavior at rates similar to non-clinical populations (psychological-inertia). In the present work, we modified and validated a well-validated paradigm from the motivation/decision making literature to compare levels of preference-differences and psychological-inertia. To measure preference-differences, people with and without schizophrenia choose between a lower-valenced and higher-valenced image. We measured the rate at which the normatively lower-valenced image was preferred. To measure psychological-inertia, both groups were given the opportunity to volitionally switch from a lower-valenced image and view a higher-valenced image. Contrary to expectations, people with schizophrenia did not differ on either preference-differences or psychological-inertia. Statistical analysis revealed that the possibility of a Type II error for even a weak effect was small. The present data suggest new avenues for research investigating mechanisms underlying avolition and clinical interventions targeting avolition in schizophrenia.

PTSD in Court II: Risk factors, endophenotypes, and biological underpinnings in PTSD.

The second article in the series of three for the journal on "PTSD in Court" especially concerns the biological bases that have been found to be associated with PTSD (posttraumatic stress disorder). The cohering concepts in this section relate to risk factors; candidate genes; polygenetics; "gene×environment" interactions; epigenetics; endophenotypes; biomarkers; and connective networks both structurally and functionally (in terms of intrinsic connectivity networks, ICNs, including the DMN, SN, and CEN; that is, default mode, salience, and central executive networks, respectively). Risk factors related to PTSD include pre-event, event- and post-event ones. Some of the genes related to PTSD include: FKBP5, 5-HTTLPR, and COMT (which are, respectively, FK506-binding protein 5 gene, serotonin-transporter linked polymorphic region, catechol-O-methyl-transferase). These genetic findings give an estimate of 30% for the genetic influence on PTSD. The typical brain regions involved in PTSD include the amygdala, hippocampus, and prefrontal cortex, along with the insula. Causal models of behavior are multifactorial and biopsychosocial, and these types of models apply to PTSD, as well. The paper presents a multilevel systems model of psychopathology, including PTSD, which involves three levels - a top-down psychological construct one, a bottom-up symptom connection one, and a middle one involving symptom appraisal. Legally, causality refers to the event at issue needing to meet the bar of being materially contributory to the outcome. Finally, this section of the article reviews empirically-supported therapies for PTSD and the dangers of not receiving treatment for it.

PTSD in Court III: Malingering, assessment, and the law.

This journal's third article on PTSD in Court focuses especially on the topic's "court" component. It first considers the topic of malingering, including in terms of its definition, certainties, and uncertainties. As with other areas of the study of psychological injury and law, generally, and PTSD (posttraumatic stress disorder), specifically, malingering is a contentious area not only definitionally but also empirically, in terms of establishing its base rate in the index populations assessed in the field. Both current research and re-analysis of past research indicates that the malingering prevalence rate at issue is more like 15±15% as opposed to 40±10%. As for psychological tests used to assess PTSD, some of the better ones include the TSI-2 (Trauma Symptom Inventory, Second Edition; Briere, 2011), the MMPI-2-RF (Minnesota Multiphasic Personality Inventory, Second Edition, Restructured Form; Ben-Porath & Tellegen, 2008/2011), and the CAPS-5 (The Clinician-Administered PTSD Scale for DSM-5; Weathers, Blake, Schnurr, Kaloupek, Marx, & Keane, 2013b). Assessors need to know their own possible biases, the applicable laws (e.g., the Daubert trilogy), and how to write court-admissible reports. Overall conclusions reflect a moderate approach that navigates the territory between the extreme plaintiff or defense allegiances one frequently encounters in this area of forensic practice.

PTSD in Court I: Introducing PTSD for Court.

The first part of the series of three articles on posttraumatic stress disorder (PTSD) in Court to appear in the journal reviews the history of the construct of PTSD and its presentation in the DSM-5 (Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition; American Psychiatric Association, 2013) and the ICD-11 (International Classification of Diseases, 11th Edition; World Health Organization, 2018). There are 20 symptoms of PTSD in the DSM-5. PTSD symptoms are arranged into a four-cluster model, which has received partial support in the literature. Other four-factor models have been found that fit the data even better than that of the DSM-5. There is a five-factor dysphoria model and two six-factor models that have been found to fit better the DSM-5 PTSD symptoms. Finally, research is providing support for a hybrid seven-factor model. An eighth factor on dissociation seems applicable to the minority of people who express the dissociative subtype. At the epidemiological level, individuals can expect trauma exposure to take place about 70% over one's lifetime. Also, traumatic exposure leads to traumatic reactions in about 10% of cases, with PTSD being a primary diagnosis for trauma. Once initiated, PTSD becomes prolonged in about 10% of cases. Polytrauma and comorbidities complicate these prevalence statistics. Moreover, the possibility of malingered PTSD presents confounds. However, the estimate for malingered PTSD varies extensively, from 1 to 50%, so that the estimate is too imprecise for use in court without further research. This first article in the series of three articles appearing in the journal on PTSD in Court concludes with discussion of complications related to comorbidities and heterogeneities, in particular. For example, PTSD and its comorbidities can be expressed in over one quintillion ways. This complexity in its current structure in the DSM-5 speaks to the individual differences involved in its expression.

Psychiatric/ psychological forensic report writing.

Approaches to forensic report writing in psychiatry, psychology, and related mental health disciplines have moved from an organization, content, and stylistic framework to considering ethical and other codes, evidentiary standards, and practice considerations. The first part of the article surveys different approaches to forensic report writing, including that of forensic mental health assessment and psychiatric ethics. The second part deals especially with psychological ethical approaches. The American Psychological Association's Ethical Principles and Code of Conduct (2002) provide one set of principles on which to base forensic report writing. The U.S. Federal Rules of Evidence (2014) and related state rules provide another basis. The American Psychological Association's Specialty Guidelines for Forensic Psychology (2013) provide a third source. Some work has expanded the principles in ethics codes; and, in the third part of this article, these additions are applied to forensic report writing. Other work that could help with the question of forensic report writing concerns the 4 Ds in psychological injury assessments (e.g., conduct oneself with Dignity, avoid the adversary Divide, get the needed reliable Data, Determine interpretations and conclusions judiciously). One overarching ethical principle that is especially applicable in forensic report writing is to be comprehensive, scientific, and impartial. As applied to forensic report writing, the overall principle that applies is that the work process and product should reflect integrity in its ethics, law, and science. Four principles that derive from this meta-principle concern: Competency and Communication; Procedure and Protection; Dignity and Distance; and Data Collection and Determination. The standards or rules associated with each of these principles are reviewed.
