Adaptive disclosure: an open trial of a novel exposure-based intervention for service members with combat-related psychological stress injuries

We evaluated the preliminary effectiveness of a novel intervention that was developed to address combat stress injuries in active-duty military personnel. Adaptive disclosure (AD) is relatively brief to accommodate the busy schedules of active-duty service members while training for future deployments. Further, AD takes into account unique aspects of the phenomenology of military service in war in order to address difficulties such as moral injury and traumatic loss that may not receive adequate and explicit attention by conventional treatments that primarily address fear-inducing life-threatening experiences and sequelae. In this program development and evaluation open trial, 44 marines received AD while in garrison. It was well tolerated and, despite the brief treatment duration, promoted significant reductions in PTSD, depression, negative posttraumatic appraisals, and was also associated with increases in posttraumatic growth.     

Questionnaire of executive function for dancers: an ecological approach

There is a current debate about the ecological validity of executive function (EF) tests. Consistent with the verisimilitude approach, this research proposes the ballet executive scale (BES), a self-rating questionnaire that assimilates idiosyncratic executive behaviors of classical dance community. The BES was administrated to 149 adolescents, students of the Cuban Ballet School. Results present a Cronbach's alpha coefficient of .80 and a split-half Spearman-Brown coefficient r (SB) = .81. An exploratory factor analysis describes a bifactorial pattern of EF dimensions, with a self-regulation component, which explains more than 40% of variance, and a Developmental component, which accounts for more than 20% of variance. The questionnaire's total scores fit linear regression models with two external criteria of academic records, confirming concurrent validity. These findings support the hypothesis that the internalization of specific contextual cultural meanings has a mediating influence in the development of EF.     

Exploration of a factor mixture-based taxonic-dimensional model of anxiety sensitivity and transdiagnostic psychopathology vulnerability among trauma-exposed adults

The aim of this study was to evaluate the associations between a factor mixture-based taxonic-dimensional model of anxiety sensitivity (AS) and posttraumatic stress, panic, generalized anxiety, depression, psychiatric multimorbidity, and quality of life among a young adult sample exposed to traumatic stress (N = 103, n (females) = 66, M (age) = 23.68 years, SD (age) = 9.55). Findings showed support for the conceptual and operational utility of the AS taxonic-dimensional model with respect to concurrent transdiagnostic vulnerability among trauma-exposed adults. Specifically, relative to the low-AS group, the high-AS group demonstrated elevated levels of panic, depressive, and posttraumatic stress symptom severity as well as greater psychiatric multimorbidity and poorer quality of life. Furthermore, past-month MDD, GAD, PTSD, and panic attacks occurred nearly exclusively among the high-AS group. Continuous AS physical and psychological concerns scores were found to be significantly related to levels of panic and posttraumatic stress symptom severity, psychiatric multimorbidity as well as panic attack status only among the high-AS group and not among the low-AS group. Findings are discussed with respect to their implications for the conceptual and operational utility of the FMM-based taxonic-dimensional model of AS, related vulnerability for psychopathology in the context of trauma, and the clinical implications of these findings for assessment and intervention.     

Indiscriminability as Indiscernibility by Default

Most solutions to the sorites reject its major premise, i.e. the quantified conditional . This rejection appears to imply a discrimination between two elements that are supposed to be indiscriminable. Thus, the puzzle of the sorites involves in a fundamental way the notion of indiscriminability. This paper analyzes this relation and formalizes it, in a way that makes the rejection of the major premise more palatable. The intuitive idea is that we consider two elements indiscriminable by default, i.e. unless we know some information that discriminates between them. Specifically, following Rough Set Theory, two elements are defined to be indiscernible if they agree on the vague property in question. Then, a is defined to be indiscriminable from b if a is indiscernible by default from b. That is to say, a is indiscriminable from b if it is consistent to assume that a and b agree on the relevant vague property. Indiscernibility by default is formalized with the use of Default Logic, and is shown to have intuitively desirable properties: it is entailed by equality, is reflexive and symmetric. And while the relation is neither transitive nor substitutive, it is “almost” substitutive. This definition of indiscriminability is incorporated into three major theories of vagueness, namely the supervaluationist, epistemic, and contextualist views. Each one of these theories is reduced to a different strategy dealing with multiple extensions in Default Logic, and the rejection of the major premise is shown to follow naturally. Thus, while the proposed notion of indiscriminability does not solve the sorites by itself, it does make the unintuitive conclusion of many of its proposed solutions—the rejection of the major premise—a bit easier to accept.     

The Principle of Summation

The principle of Summation, which is a technically sharpened version of the familiar claim that a whole is a sum of its parts, is presented by Peter van Inwagen as a trivial truth. I argue to the contrary, that it is incompatible with the natural assumption that a whole may gain or lose parts non-instantaneously. For, as I show, the latter assumption implies that something can be determinately a whole without being determinately a sum of parts, and this, in turn, indicates the falsity of Summation. I point out that the tension between Summation and the possibility of non-instantaneous gain or loss of parts compels us to rethink the relations between the concepts of whole and sum, and may have far reaching consequences for the mereology of physical objects.

THE NATURE OF HOPE

Both traditional accounts of hope and some of their recent critics analyze hope exclusively in terms of attitudes that a hoper bears towards a hoped-for prospect, such as desire and probability assignment. I argue that all of these accounts misidentify cases of despair as cases of hope, and so misconstrue the nature of hope. I show that a more satisfactory view is arrived at by noticing that in addition to the aforementioned attitudes, hope involves a characteristic attitude towards an external factor, on whose operation the hoper takes the prospect's realization to depend causally.     

A Measure for the Reliability of a Rating Scale Based on Longitudinal Clinical Trial Data

A new measure for reliability of a rating scale is introduced, based on the classical definition of reliability, as the ratio of the true score variance and the total variance. Clinical trial data can be employed to estimate the reliability of the scale in use, whenever repeated measurements are taken. The reliability is estimated from the covariance parameters obtained from a linear mixed model. The method provides a single number to express the reliability of the scale, but allows for the study of the reliability’s time evolution. The method is illustrated using a case study in schizophrenia. The authors are grateful to J&J PRD for kind permission to use their data.

The Influence of Children on Their Parents’ Values

Many parents report that their values are influenced by their children. However, few studies provide direct evidence regarding child–parent value transmission. We review this evidence and propose five main processes of child influence: (i) Passive child influences, causing change in parental values by the mere presence or development of children; (ii) Active child influences, due to children directly attempting to influence their parents’ opinions or providing parents with relevant information; (iii) Differentiation, the emergence of a distinction between parents’ own personal values and their socialization values; (iv) Reciprocal influences; in which parents’ and children’ influences are intertwined; and (v) Counter‐influences, in which parental values change in a direction opposite to that of children's values. A study on child influence illustrates some of these processes. The roles of migration, aging, and parent and child characteristics in child‐to‐parent influences are discussed.     

Internalized transphobia: Exploring perceptions of social messages in transgender and gender-nonconforming adults

Background: Transgender and gender nonconforming (TGNC) individuals encounter a variety of minority stressors that have yet to be fully articulated or explored within the research literature. The purpose of this study is to better understand internalized stigma—the experience of accepting and internalizing negative social messages and experiences about one's identity—an underexplored minority stressor for TGNC people.

Method: We conducted in-depth interviews with 30 diverse TGNC participants using consensual qualitative research (CQR) methodology.

Results: Following data saturation and analysis, six distinct themes emerged across participants: (1) TGNC identities are regarded negatively by society; (2) social messages are perceived as originating from the media and religious ideology; (3) TGNC individuals report emotional distress; (4) negative self-perceptions in response to social messages; (5) TGNC individuals report resilience processes in response to negative social messages; and (6) social messages are perceived generally to differentially impact TGNC people of color.

Conclusion: Findings highlight the common experience of encountering social marginalization for TGNC individuals. Structural interventions that target pervasive sociocultural messages regarding TGNC identities are warranted.     

Prosocial behavior from early to middle childhood: genetic and environmental influences on stability and change

Prosocial behavior is important for the functioning of society. This study investigates the extent to which environment shared by family members, nonshared environment, and genetics account for children's prosocial behavior. The prosocial behavior of twins (9,424 pairs) was rated by their parents at the ages of 2, 3, 4, and 7 and by their teachers at age 7. For parent ratings, shared environmental effects decreased from .47 on average at age 2 to .03 at age 7, and genetic effects increased from .32 on average to .61. The finding of weak shared environmental effects and large heritability at age 7 was largely confirmed through the use of teacher ratings. Using longitudinal genetic analyses, the authors conclude that genetic effects account for both change and continuity in prosocial behavior and nonshared environment contributes mainly to change.
