Peritraumatic dissociation and PTSD severity: do event-related fears about death and control mediate their relation?

Relations among peritraumatic dissociation, PTSD severity, event-related fear (i.e. fear experienced during traumatic event) about death, and event-related fear about losing control were examined in the current study. Particular emphasis was placed on testing whether or not fears about death and losing control mediate the relation between peritraumatic dissociation and PTSD severity in a sample of 146 nontreatment-seeking university women. Results indicated that event-related fears about death and losing control accounted for the relation between peritraumatic dissociation and PTSD severity; that is, the effect of peritraumatic dissociation on PTSD severity was eliminated after controlling for these fears. Speculations about findings are discussed.     

When plausibility manipulations work: An examination of their role in the development of false beliefs and memories

In the current study we examined whether prevalence information and imagery encoding influence participants' general plausibility, personal plausibility, belief, and memory ratings for suggested childhood events. Results showed decreases in general and personal plausibility ratings for low prevalence events when encoding instructions were not elaborate; however, instructions to repeatedly imagine suggested events elicited personal plausibility increases for low-prevalence events, evidence that elaborate imagery negated the effect of our prevalence manipulation. We found no evidence of imagination inflation or false memory construction. We discuss critical differences in researchers' manipulations of plausibility and imagery that may influence results of false memory studies in the literature. In future research investigators should focus on the specific nature of encoding instructions when examining the development of false memories.     

Family business: A fertile ground for research on time,teams and positive organizational study

Further reflecting on the study of organizational behaviour (OB) in family business (FB), this rejoinder piece discusses and integrates the points raised in the three thoughtful commentaries and our original article. We start by highlighting the general agreement between us and the commentators on three points: (1) that family firms are theoretically distinct from non-family firms due to significant involvement of kinship ties in the enterprise; (2) there is paucity of research at the interface of OB and FB and (3) there is an abundance of interesting research questions at this interface with the potential to benefit both domains of study. Next, we discuss and elaborate on the research possibilities on time, teams and positive organizational study, suggested by the commentators. An illustrative list of interesting research questions at the OB–FB interface that extend and enrich our agenda for future research is shared. We conclude that not only is FB a promising context for behavioural scholars to investigate, the timing is perfect for such investigations.     

Effects of Age and Control Beliefs on Resource Allocation During Reading Abstract

Past work suggests that a strong sense of control over one's cognitive ability is associated with higher levels of cognitive performance and that control beliefs may be even more important in later life, due to age-related declines in cognitive processes. However, less is known about the effects of control beliefs on encoding strategies, and whether these effects are comparable for younger and older adults. Participants were divided into high- (HC) and low- control (LC) beliefs groups based on their scores on the Personality in Intellectual-Aging Contexts Inventory. Participants then read relatively easy and difficult passages word-by-word on a computer for subsequent recall. The data suggest that among older, but not younger adults, control beliefs are particularly important when reading difficult passages. Findings as they relate to models of self-regulation and to implications for everyday functioning are discussed.     

To Follow Expert Advice When Making a Decision: An Examination of Reactive Versus Reflective Autonomy

The present study examined whether reactive and reflective autonomy moderated individuals' responses to expert influence. Participants were given the opportunity to win money at a racetrack betting task for which they were provided with objective information about horses' previous performances along with specific expert recommendations. The experts were made to look either credible or noncredible by manipulating information on the success rate of their previous predictions. The results showed that the two forms of autonomy led to exactly opposite behaviors in response to the advice of credible experts. Reflective autonomy was significantly positively associated with following the recommendations of credible experts whereas reactive autonomy was significantly negatively associated with following the recommendations. The results also showed that it was particularly after losing their first race that reactive autonomy was related to rejecting the advice of experts. These findings indicate that reactive and reflective forms of autonomy may yield opposite patterns of behavior in certain situations.     

The flexible application of a manualized treatment for PTSD symptoms and functional impairment related to the 9/11 World Trade Center attack

The purpose of this treatment effectiveness study was to evaluate the flexible application of a manualized cognitive behavioral treatment (CBT) for PTSD and related symptoms in survivors of the 9/11 terrorist attack on the World Trade Center. Treatment delivery ranged from 12 to 25 sessions; therapist experience ranged from no prior training to extensive training in CBT; and training and supervision of clinicians in the treatment manual was considerably less than that required in a randomized clinical trial (RCT). Paired t-tests demonstrated significant pre-post reductions in symptoms of PTSD and depression for the flexible application of the treatment. A benchmarking analysis revealed that the moderate-to-large effect sizes found for these variables were similar to those obtained in an RCT of the same treatment. Furthermore, effect sizes on measures of outcomes particularly relevant to this population of mass violence survivors such as functional impairment, use of alcohol and drugs to cope, and use of social support to cope, were also medium to large.     

The relationship between childhood abuse and adult personality disorder symptoms

This study assessed personality disorder symptomatology in a community sample of healthy adults without diagnosable DSM-IV-TR Axis I psychiatric disorders who reported a history of childhood abuse. Twenty-eight subjects with a history of moderate to severe physical, sexual, and/or emotional abuse according to the Childhood Trauma Questionnaire were compared to 33 subjects without an abuse history on symptoms of personality disorders. Subjects in the Abuse group were more likely to report subclinical symptoms of paranoid, narcissistic, borderline, antisocial, obsessive compulsive, passive-aggressive, and depressive personality disorders. These findings link reports of childhood abuse with symptoms of personality disorders in the absence of Axis I psychiatric disorders in a community sample of healthy adults.
