Factor Structure of the Dissociative Experiences Scale: An Examination Across Sexual Assault Status

The Dissociative Experiences Scale (DES) has a long history within the literature, with conflicting reports concerning its underlying components and stability across different samples. This study examined the DES factor structure using advanced analytic procedures. Additionally, the impact of sexual victimization on the underlying components of the DES was explored, in order to examine whether sexual trauma influenced the scale’s structure. In Study 1, exploratory factor analysis suggested the possibility of either a 1- or 2-factor structure in DES data obtained from an unselected sample of college females. Comparison of these models using an independent validation sample in Study 2 observed a clear advantage of a 2-factor structure. Study 3 explored whether sexual assault status influenced the structure of the 2-factor DES model, using samples drawn from Studies 1 and 2. A multiple group confirmatory factor analysis supported a robust 2-factor structure for the DES irrespective of sexual assault status.     

Exploring the Clinical Implications of the International CS Reference Data for Children and Adolescents (Meyer,Erdberg, & Shaffer, 2007)

As part of an ongoing study on the prediction of suicide, a replication study was carried out on the Neuropsychiatric Hospital Suicide Potential Scale (NPHSPS), a recently constructed schedule for prediction of potentiality for committed suicide among hospitalized neuropsychiatric patients at the time of release from the hospital. The population consisted of 54 patients who had committed suicide and 50 patients who had not. Overall accuracy of the scale was 81.7 percent, with 95.2 percent accuracy for prediction of the high risk group and 80.0 percent accuracy for prediction of nonsuicidal controls. By computation of posterior probability, the scale is shown to increase accuracy of prediction more than five-fold over use of the base rate (or prior probability) alone, but it is also evident the level of prediction of suicide is still too minimal to permit individual clinical application.     

Inequality and the Altruistic Life: A Study of the Priestly Vocation Rate

This article takes the rate of new incorporations into the Catholic priesthood within national societies as a social fact revealing underlying societal tendencies of broad theoretical relevance extending well beyond the study of religion. Our emphasis lies on the impact of income inequality on the prevalence of altruistic life options. We examine cross‐national and time‐series variation in the priestly vocation rate as the empirical foundation to theorize social dynamics underpinning a life option that entails the renunciation of opportunities for individual material advantage alongside the commitment to serve a broader community. The article elaborates why we view the vocation rate as resting on a combination of piety and altruistic dispositions, and provides a theoretical rationale for expecting inequality to diminish this—and other—altruistic life options. We also examine the impact of other variables that have been theorized to influence the prevalence of Catholic clerical vocations and elaborate the broader theoretical relevance of our empirical findings.     

Testing Our Quasi‐Statistical Sense: News Use,Political Knowledge,and False Projection

Although widely studied, previous research of projection in the context of public opinion did not incorporate the distinction between adequate and false projection developed in the cognitive studies: Adequate projection contributes to accurate perceptions of public opinion while false projection impairs it. The analysis presented in this study includes the above distinction, building on two case studies: (1) a dataset comprised of 25 surveys conducted over a period of 10 years (N = 11,313) and (2) a panel study of the 2013 Israeli general election. Relying on the assumptions of the Bayesian model, we tested if frequent news exposure and factual political knowledge reduce false projection. We found that false projection is a highly persistent psychological tendency with little variance. Although news exposure and political knowledge did contribute to a more accurate perception of public opinion, they did not reduce false projection. Conversely, knowledge increased false projection among moderates and had no effect in this respect among proponents of a more extreme ideology. These findings align better with the motivated reasoning model than with the Bayesian model.     

The Probability of Iterated Conditionals

Iterated conditionals of the form If p, then if q, r are an important topic in philosophical logic. In recent years, psychologists have gained much knowledge about how people understand simple conditionals, but there are virtually no published psychological studies of iterated conditionals. This paper presents experimental evidence from a study comparing the iterated form, If p, then if q, r with the “imported,” noniterated form, If p and q, then r, using a probability evaluation task and a truth‐table task, and taking into account qualitative individual differences. This allows us to critically contrast philosophical and psychological approaches that make diverging predictions regarding the interpretation of these forms. The results strongly support the probabilistic Adams conditional and the “new paradigm” that takes this conditional as a starting point.     

Unnoticed intrusions: Dissociations of meta-consciousness in thought suppression

The current research investigates the interaction between thought suppression and individuals’ explicit awareness of their thoughts. Participants in three experiments attempted to suppress thoughts of a prior romantic relationship and their success at doing so was measured using a combination of self-catching and experience-sampling. In addition to thoughts that individuals spontaneously noticed, individuals were frequently caught engaging in thoughts of their previous partner at experience-sampling probes. Furthermore, probe-caught thoughts were: (i) associated with stronger decoupling of attention from the environment, (ii) more likely to occur under cognitive load, (iii) more frequent for individuals with a desire to reconcile, and (iv) associated with individual differences in the tendency to suppress thoughts. Together, these data suggest that individuals can lack meta-awareness that they have begun to think about a topic they are attempting to suppress, providing novel insight into the cognitive processes that are involved in attempting to control undesired mental states.     

Combat-Related Killing: Expanding Evidence-Based Treatments for PTSD

Despite its prevalence, killing in war is an experience that may not fit neatly into existing models of posttraumatic stress disorder (PTSD) and its treatment. The context in which killing occurred may be complex. Furthermore, while killing may certainly be fear based, an individual may have also killed in response to losing someone close and experiencing sadness and anger, as opposed to fear. While evidence-based treatments for PTSD may be a good starting point for killing-related trauma, we argue that existing treatments need to be expanded. Complex killing-related cognitions that may not be anticipated or identified, moral injury, self-forgiveness, and loss are all important issues that arise that may need to be addressed in greater detail. Consequently, we have developed a 6- to 8-session individual treatment module for those impacted by killing in war, expressly designed for use with existing evidence-based treatments for PTSD, currently being validated for use in clinical practice. We see this module as supplementary, rather than as a replacement, building on the skills that veterans have already learned within these treatments. By expanding the types of treatments we offer those who have killed in war, we can ensure that we are providing veterans with comprehensive treatment that takes the complexities of war and its aftermath into account.     

Suicide Crisis Syndrome: A review of supporting evidence for a new suicide‐specific diagnosis

Suicide is a major public health problem, and suicide rates are still on the rise. Current strategies for identifying individuals at risk for suicide, such as the use of a patient's self‐reported suicidal ideation or evidence of past suicide attempts, have not been sufficient in reducing suicide rates. Recently, research groups have been focused on determining the acute mental state preceding a suicide attempt. The development of an acute suicidal diagnosis, the Suicide Crisis Syndrome (SCS), is aimed at capturing this state to better treat individuals. The SCS has five main evidence‐based components—entrapment, affective disturbance, loss of cognitive control, hyperarousal, and social withdrawal. The SCS may provide clinicians with the ability to identify individuals who are experiencing an acute pre‐suicidal mental state, regardless of their self‐reported suicidal ideation. Future research leading to the incorporation of this diagnosis into clinical practice could improve the quality of care and reduce the personal, societal, and legal burden of suicide.
