A preliminary examination of the role of psychotherapist fidelity on outcomes of cognitive processing therapy during an RCT for military sexual trauma-related PTSD

While cognitive processing therapy (CPT) is an effective evidence-based treatment for many veterans with military-related post-traumatic stress disorder (PTSD), not all veterans experience therapeutic benefit. To account for the discrepancy in outcomes, researchers have investigated patient- and research design-related factors; however, therapist factors (e.g. fidelity) have received less attention. The present study is a preliminary examination of the effect of psychotherapists’ fidelity during CPT on clinical outcomes during a randomized clinical trial (RCT) for military sexual trauma-related PTSD. PTSD symptoms, trauma-related negative cognitions (NCs), and depression symptoms were assessed for 72 participants at baseline, and 1-week, 2-month, 4-month, and 6-month posttreatment. Of the four CPT therapists, two were found to have significantly poorer (i.e. “below average”) treatment fidelity scores compared to the other two therapists who had “good” treatment fidelity scores. To examine possible therapist effects on outcomes, hierarchical linear modeling was utilized with therapist fidelity entered as a Level 2 predictor. Participants treated by a therapist with “good” treatment fidelity experienced significantly greater reductions in PTSD symptoms, NCs, and depression symptoms than patients treated by a therapist with “below average” treatment fidelity. Our preliminary findings highlight the importance of monitoring, maintaining, and reporting fidelity in psychotherapy treatment RCTs.     

Excitatory conditioning of individual Drosophila melanogaster

Testing individual animals from a heterogenic population of Drosophila melanogaster, we demonstrate conditioning of the proboscis extension reflex. The presentation of paired (conditioning) stimuli produced (a) an increase in the average number of conditioned responses over trials, (b) measured differences in performance levels among individual subjects, and (c) a sex difference, with more males conditioned than females, and those that did did so more quickly. The presentation of unpaired (control) stimuli produced significantly lower average levels of acquisition responding and a change in the distribution of individual response patterns. Neither central excitatory state nor sensitization induced by the conditioned or unconditioned stimuli directly affected the conditioned response, whereas unconditioned stimulus preexposure adversely affected performance levels. Presenting the unpaired (extinction) stimuli after conditioning produced less of a decline in responding than did an extinction procedure with removal of the unconditioned stimulus. With the ability to identify individual differences in acquisition and extinction patterns, and given the relatively large number of individuals that can be tested simultaneously on the automated stimulation apparatus, it is now possible to make precise behavioral measurements on samples large enough for the behavior-genetic analysis of D. melanogaster with conditioning as the phenotype.     

Selection for conditionability in Drosophila melanogaster.

Successful bidirectional selective breeding of Drosophila melanogaster for excitatory conditionability is reported, using the reliable measures of individual differences (first described by Holliday & Hirsch, 1984, 1986a, 1986b) to test 1,324 animals. Bidirectional selective breeding for good and poor conditioning has produced, respectively, one population in which the percentage of animals showing good conditioning has increased over 25 generations from 19% to 77% and another in which it has decreased over 23 generations to 0%-4%. No increase in a measure of sensitization induced by an unconditioned stimulus (the central excitatory state) accompanied the increase in the percentage of good conditioners in the population selected for good conditioning, whose level of conditioned responding exceeds that of the sensitization measure.     

Psychodynamic assessment of changes in children with autism under psychoanalytic treatment

In this article the authors report insights into autism developed through their extensive experience of psychoanalytic therapy with children with autism. The fi rst stages of body psychic development are seriously disrupted by this pathology, resulting in primitive anxieties of falling and of being liquefi ed. These anxieties are connected to the fragile development of body ego and of its related spatiotemporal organisation. The changes in children observed by the authors during the therapeutic process lead them to offer a psychodynamic assessment tool, which revolves principally around the development of body ego. After the initial state of 'severe autism', the authors describe three stages: the stage of 'recovery of the skin' (Bick); the established 'symbiotic phase', subdivided into 'vertical then horizontal splitting of the body ego'; and fi nally the stage of 'individuation'. First, the authors describe the principal psychoanalytic approaches to autism and refl ect on the links possible with nonpsychoanalytic work.     

Who Is a Good Organizational Citizen? Social Perception of Male and Female Employees Who Use Family Leave

In this study, we examined perceptions of the citizenship behaviors of male and female employees who took leave to care for a newborn, a sick child, a sick parent, or who did not take leave. In a 2 (employee gender) × 4 (reason for leave) × 2 (participant gender) experimental design, 242 undergraduate students read a mock personnel file and rated the employee on altruism and generalized compliance. Female employees were not rated differently whether they took leave or not. Male employees who took leave for birth or eldercare were rated less likely to be altruistic at work than their male counterparts who did not take leave and their female counterparts who took leave. There was also a bias against male leave takers for generalized compliance ratings, especially by male evaluators. Future research ideas and implications for organizational practice are discussed.     

Automatic and intentional processes in children's recognition memory: the reversed misinformation effect

This study investigated the contribution of automatic and intentional memory processes to 5‐ and 6‐year‐old children's suggestible responses in a reversed misinformation paradigm. The temporal order of the conventional eyewitness paradigm was altered such that children were initially presented with a pre‐event narrative containing misinformation that was either read to them or was self‐generated in response to semantic and linguistic cues, and the following day were presented with a witnessed event in the form of a picture story. Children then completed a standard forced‐choice recognition memory test under two instruction conditions. In the inclusion condition children were reminded about the presentations of the pre‐event narrative and the original story and asked to chose the witnessed event item. In the exclusion condition children were instructed to exclude pre‐event suggestions. Suggestibility effects were found with the magnitude of such effects differentially affected by the encoding of misleading suggestions and test instructions. In the exclusion condition, children were more likely to correctly reject suggestions that were ‘self‐generated’. Both automaticity and intentional recollection contributed to children's suggestible responding. Copyright © 2002 John Wiley & Sons, Ltd.     

Understanding developmental reversals in false memory: Reply to Ghetti (2008) and Howe (2008)

Replies to comments on the current authors' original article. S. Ghetti (2008) and M. L. Howe (2008) presented probative ideas for future research that will deepen scientific understanding of developmental reversals on false memory and establish boundary conditions for these counterintuitive patterns. Ghetti extended the purview of current theoretical principles by formulating hypotheses about how developmental reversals are controlled by the growth of phantom recollection and by the growth of false-memory editing. Some data are available on her hypotheses about phantom recollection, which distinguish phenomenology (vague or vivid) from memory representation (verbatim or gist). Howe introduced alternative theoretical principles that can be traced to the early work of Deese and Underwood. He argued that fuzzy-trace theory is subject to 3 limitations and that his alternative conception makes 3 predictions that contrast with fuzzy-trace theory's predictions. In the current reply, it is shown that the stated limitations do not apply to fuzzy-trace theory, that previously published research runs counter to the 3 predictions, and that the core difference between the 2 approaches is that fuzzy-trace theory is an opponent-processes model whereas the alternative conception is a 1-process model.

Attention to global gist processing eliminates age effects in false memories

Counterintuitive age increases have been reported for the Deese-Roediger-McDermott (DRM) false memory illusion. The current theoretical explanation of this effect assumes that it is due to age increases in spontaneous interconnection of DRM list words' meanings. To test this explanation, 11-year-olds and young adults studied DRM lists under conditions that (a) encouraged them to form such meaning-based connections or (b) discouraged them from doing so. In line with the explanation, the usual developmental increase in false memory disappeared in the first condition but was preserved in the second condition. Also in line with the explanation, conjoint recognition analyses revealed that encouraging participants to form meaning connections increased their reliance on gist-based similarity judgments.     

Enhancing the recall of young,young–old and old–old adults with cognitive interviews

Two studies examined whether a Cognitive Interview improves older witnesses' recall. Study 1 compared the quality and quantity of older adults' recall when given a typical UK police interview, the Enhanced Cognitive Interview (ECI), or a modified version of the Cognitive Interview (MCI). The MCI was identical to the ECI except that the change perspective technique was omitted. Old–old (75–95‐years) adults' recall was less complete and less accurate than that of young–old (60–74‐years) adults, which was less complete and accurate than that of young (17–31‐years) adults. The ECI and MCI increased the number of correct Person, Action, Object and Surrounding details reported across every age group, without increasing the number of incorrect or confabulated details recalled. In Study 2, it was found that these effects remained when interviews were re‐scored using a system that reflected police officers' decisions about the investigative relevance of details.
