Detection of Feigned Posttraumatic Stress Disorder: A Comparison of the MMPI-2 and PAI

The Minnesota Multiphasic Personality Inventory-2 (MMPI-2) and Personality Assessment Inventory (PAI) were compared for detecting feigned posttraumatic stress disorder (PTSD) in a simulation research design. Participants were 85 undergraduates in one of three groups: PTSDs (n = 23), Fakers (n = 31), and Controls (n = 31). As expected, both the MMPI-2 and PAI discriminated PTSDs and Controls, with PTSDs scoring significantly higher on fake-bad validity scales and PTSD-relevant clinical scales. However, only the MMPI-2 discriminated Fakers and PTSDs, with Fakers scoring significantly higher on all MMPI-2 scales considered, but on only one PAI scale. Further, in logistic regression analyses the MMPI-2 demonstrated higher overall correct classification of PTSDs and Fakers than did the PAI. Although the MMPI-2 outperformed the PAI in detecting feigned PTSD, a substantial proportion of Fakers avoided detection by MMPI-2 fake-bad validity scales, suggesting that both tests are vulnerable to feigning of PTSD by motivated respondents with relatively limited coaching.     

Participatory practices and political knowledge: how motivational inequality moderates the effects of formal participation on knowledge

Democracies rely upon politically knowledgeable citizens for their legitimacy and to sustain themselves. In Australia, policy initiatives have addressed concerns about the low levels of political knowledge among young people. Yet research about how young Australians acquire political knowledge, beyond schools, is scarce. The present study referring to the concepts of situated learning, self-determination and knowledge gap, asks whether young adult’s participatory practices (e.g., participation in politics, prior involvement in decision-making at school) predict political knowledge. Analyses that control for multiple predictors of political knowledge suggest differential associations between political knowledge and different participatory practices. Motivational inequality, as defined by interest in politics, moderates the associations with party-political participation and participation at school; the conditional effect of party-related political participation is further moderated by educational resources. Gendered differences are identified for some participatory practices. Directions for future research and the importance of participatory experiences and how to establish a foundation of young citizens’ political knowledge are discussed.

     

The Comprehensive Resource Model®: Overview of basic affects in adversity & effective treatment for complex reactions to trauma

Much of the theoretical focus in post‐traumatic stress disorder has been on the role of the amygdala, the hippocampus and the prefrontal cortex. Crucially, in unresolved traumatic experiences that underlie clinical presentations, this focus misses the brain areas key to the defence responses of fight, flight and freeze—and the associated affects of anger, fear and grief. The periaqueductal gray in the midbrain, with the hypothalamus, is essential for these somatic and emotional responses to traumatic experiences. We argue that when treatment approaches thought to work at the higher brain levels have been ineffective, it is because they have failed to engage the midbrain and hypothalamic sources of the affective responses to the trauma and to the memory of it. Basic affects have been so overwhelming that dissociation, or a similarly protective neurochemical capping mechanism, has prevented full resolution of the affective content of the adversity. Treatment with the Comprehensive Resource Model^® (CRM) aims to clear the clinically relevant residues of adverse experiences by resolving the emotional responses accessed through the body memories. When the trauma has led to overwhelming distress, and/or dissociation, there is a necessity for robust resourcing to be in place before the emotional intensity of that distress is accessed. Resourcing needs to be as proximal to the re‐experience as possible to promote complete resolution and in some psychotherapy modalities, the supports provided are somewhat remote from the crucial moments of processing. Therefore, we describe how the CRM seeks to have robustly resourced states present concurrently with traumatised states to avoid overwhelming emotional distress. This allows safe entry into the deepest pain residual from the traumatic event so that it is not overwhelming during processing of the memory, and does not lead to further dissociation, allowing the individual to remain fully present throughout. This “stepping into the affect” can then be so rapidly effective that we also argue that CRM is not an exposure treatment; re‐orientation to the deepest content of the experience resolves the residual distress quickly and permanently through memory reconsolidation. Re‐learning at upper brain levels will then follow from the revoking of the affective power, which has previously driven stimulus/context and response learning in the amygdala, hippocampus and prefrontal cortex.

A balanced time perspective: Is it an exercise in empiricism,and does it relate meaningfully to health and well‐being outcomes?

Time perspective research assesses the degree to which thoughts and feelings about the past, present and future influence behaviour, and a balanced time perspective profile has been posited as being ideal. Although this area of research has seen a move towards person‐centred analyses, using either cluster analyses or a deviation from balanced time perspective (DBTP) approach, there are a number of theoretical and methodological issues that must be addressed. Using data from diverse samples in four countries, the present study used both cluster analyses and the DBTP approach to assess how cluster membership and DBTP scores related to a range of health and well‐being outcomes. As in previous studies, a balanced profile only emerged once in cluster analyses, and positive‐oriented profiles were associated with optimal outcomes. The study also found evidence of a relationship between DBTP scores and scores on well‐being indicators. However, results gained after manipulating the DBTP equation in two different ways again indicated that higher than expected positive past and present or past and future scores were responsible for the positive outcomes. As such, these findings raise concerns regarding the use of the DBTP construct within clinical settings.     

Unequally into “Us”: Characteristics of Individuals in Asymmetrically Committed Relationships

This study examined characteristics of individuals that are associated with being in asymmetrically committed relationships (ACRs), defined as romantic relationships in which there was a substantial difference in the commitment levels of the partners. These ACRs were studied in a national sample of unmarried, opposite‐sex romantic relationships (N = 315 couples). Perceiving oneself as having more potential alternative partners was associated with increased odds of being the less committed partner in an ACR compared to not being in an ACR, as was being more attachment avoidant, having more prior relationship partners, and having a history of extradyadic sex during the present relationship. Additionally, having parents who never married was associated with being the less committed partner in an ACR but parental divorce was not. Although fewer characteristics were associated with being the more committed partner within an ACR, more attachment anxiety was associated with increased odds of being in such a position compared to not being in an ACR. We also address how some findings change when controlling for commitment levels. Overall, the findings advance understanding of commitment in romantic relationships, particularly when there are substantial asymmetries involved. Implications for both research on asymmetrical commitment as well as practice (e.g., therapy or relationship education) are discussed.     

Optimal Item Calibration for Computerized Achievement Tests

Item calibration is a technique to estimate characteristics of questions (called items) for achievement tests. In computerized tests, item calibration is an important tool for maintaining, updating and developing new items for an item bank. To efficiently sample examinees with specific ability levels for this calibration, we use optimal design theory assuming that the probability to answer correctly follows an item response model. Locally optimal unrestricted designs have usually a few design points for ability. In practice, it is hard to sample examinees from a population with these specific ability levels due to unavailability or limited availability of examinees. To counter this problem, we use the concept of optimal restricted designs and show that this concept naturally fits to item calibration. We prove an equivalence theorem needed to verify optimality of a design. Locally optimal restricted designs provide intervals of ability levels for optimal calibration of an item. When assuming a two-parameter logistic model, several scenarios with D-optimal restricted designs are presented for calibration of a single item and simultaneous calibration of several items. These scenarios show that the naive way to sample examinees around unrestricted design points is not optimal.

     

The League

About painting, cybernetics, and shared purpose, this article is partly a story, in part a memoir, an adventure in cybernetics, happening 30 years ago, in snow, in the small Swiss city of St. Gallen. A conference of the American Society for Cybernetics meets there. It is 1987. The author, a painter, searching for a new understanding of painting, encounters a convergence of the art of painting and the art of cybernetics through principles of second-order cybernetics in Pask, von Foerster and Maturana, dissolved in Kathleen Forsythe’s poetry. The form, as well as the content of this article, reflects cybernetics.     

The language of lies: a preregistered direct replication of Suchotzki and Gamer (2018; Experiment 2)

Is lying in a different language easier or more difficult? The Emotional Distance and the Cognitive Load hypothesis give competing answers. Suchotzki and Gamer measured the time native German speakers needed to initiate honest and deceptive answers to German and English questions. Lie-truth differences in RTs were much smaller for the foreign compared to the native language. In our preregistered replication study in native Dutch speakers, we found that lie-truth differences in RTs were moderately smaller when participants were tested in English than when tested in Dutch. These findings indicate that people struggle with quickly retrieving the truth in another language, and that foreign language use may diminish lie-truth differences.
