Assessment of DSM-IV personality disorders in obsessive-compulsive disorder: comparison of clinical diagnosis, self-report questionnaire, and semi-structured interview

In patients with obsessive-compulsive disorder, personality disorders are not many times assessed according to DSM-IV criteria. The purpose of the present study is to examine the prevalence of personality disorders diagnosed according to the DSM-IV in a severely disordered OCD population (n=65) with three different methods of assessing personality disorders (structured interview, questionnaire, and clinical diagnoses). Furthermore, correspondence between these different methods was investigated and their construct validity was examined by relating the three methods to external variables. Each method resulted in a predominance of Cluster C personality disorders, and obsessive-compulsive personality disorder had the highest prevalence. However, there was generally low correspondence regarding which patient had which personality disorder. Results concerning the relation of external variables were the most promising for the structured clinical interview.     

Interelectrode distance and warning signal interval and the evaluation of clinical electrical shock

Contingent shock is used on a small scale for behaviors that may lead to severe damages to one's body or to others. Research efforts focus on exploring variables that control the evaluation of electrical shocks. This study focuses on two practical questions, that is, whether the distance between the electrodes would influence the evaluation of shock and whether using a variable time interval in the administration would influence the evaluation of shock. Results reveal that both investigated variables control the evaluation of shock. Multiple shocks appear to produce a stronger sensation than single shocks, a phenomenon that was also revealed in previous studies. Copyright © 2009 John Wiley & Sons, Ltd.

EMDR: eye movements superior to beeps in taxing working memory and reducing vividness of recollections

Posttraumatic stress disorder (PTSD) is effectively treated with eye movement desensitization and reprocessing (EMDR) with patients making eye movements during recall of traumatic memories. Many therapists have replaced eye movements with bilateral beeps, but there are no data on the effects of beeps. Experimental studies suggest that eye movements may be beneficial because they tax working memory, especially the central executive component, but the presence/degree of taxation has not been assessed directly. Using discrimination Reaction Time (RT) tasks, we found that eye movements slow down RTs to auditive cues (experiment I), but binaural beeps do not slow down RTs to visual cues (experiment II). In an arguably more sensitive “Random Interval Repetition” task using tactile stimulation, working memory taxation of beeps and eye movements were directly compared. RTs slowed down during beeps, but the effects were much stronger for eye movements (experiment III). The same pattern was observed in a memory experiment with healthy volunteers (experiment IV): vividness of negative memories was reduced after both beeps and eye movements, but effects were larger for eye movements. Findings support a working memory account of EMDR and suggest that effects of beeps on negative memories are inferior to those of eye movements.     

Validation of the DynaPort MiniMod during sleep: a pilot study

To measure activity during sleep, polysomnography and actigraphy are often used. The DynaPort MiniMod measures movement intensity and body position day and night. The goal was to examine the validity of the DynaPort MiniMod in assessing physical activity and body posture during sleep. In Study A, 10 healthy participants slept with the DynaPort MiniMod and the Actiwatch for one night. In Study B, 8 participants suspected of having Obstructive Sleep Apnoea Syndrome slept for one night with the DynaPort MiniMod and underwent complete polysomnography as part of the typical care protocol. In Study A, there was a significant moderate correlation (r = .70) between the movement scores of the Actiwatch and the DynaPort MiniMod. In Study B, a high intraclass correlation (r = .84) between body posture scores of the DynaPort MiniMod and the polysomnography position sensor was observed. The DynaPort MiniMod is a valid measurement device for physical activity during sleep.     

Temporary and Long-Term Consequences of Bereavement on Happiness

In this article, we examine the temporary and long-term consequences of the death of a parent or child on happiness. According to set-point theory external conditions are expected to only have a short-term or limited influence on happiness. This directly contradicts the basic assumption of affective theories on happiness, which states that major life-events have a lasting influence on well-being. Moreover, we test whether the association between bereavement and happiness is equally strong across the life course. To test our hypotheses we make use of the fourth wave of the European Values Study. Our research findings demonstrate that people who lost their father, mother or child are more likely to feel unhappy than people without this experience. Ten years after the death of a parent or child we still find a significant difference in happiness between people who have and have not experienced this loss. The assumption of set-point theory, that major life evens only have a temporary impact on SWB, is not supported by our data. Moreover, the association between bereavement and SWB strongly differs across the life-course. We might even conclude that the age at which the loss occurred is more decisive for the strength of the association between bereavement and SWB than the duration of the loss.     

Pre-stressor cognitive control is related to intrusive cognition of a stressful film

It has been suggested that relatively weak cognitive control existing prior to a stressful event may be associated with intrusive memories of that stressor afterwards. We explored this in two analog studies employing unselected participants who saw an emotional film fragment and completed behavioral (i.e., color-naming interference [CNI]) and self-report indices of intrusions. Prior to film presentation, several cognitive control tests were administered. Study 1 showed that better updating/monitoring was linked to less CNI from negative film-related words. However, better updating/monitoring was associated with more diary reports of intrusive memories. Study 2 showed that a better resistance to pro-active interference (PI) predicted less self-reported film-related intrusive cognition after 24h. However, after this delay, both self-reported intrusions and CNI were not related to updating/monitoring. Taken together, the results suggest that a specific pre-existing cognitive control function (i.e., resistance to PI) may be involved in the regulation of post-stressor intrusive memory phenomena.     

Portable Myoelectric Brace Use Increases Upper Extremity Recovery and Participation But Does Not Impact Kinematics in Chronic,Poststroke Hemiparesis

The authors examined the efficacy of an 8-week regimen combining repetitive task-specific practice (RTP) with a myoelectric brace (RTP+Myomo) on paretic upper extremity (UE; use in valued activities, perceived recovery, and reaching kinematics) in 12 subjects (4 men; M age = 53.5 years; mean time poststroke = 61.7 months). Seven subjects were administered RTP+Myomo therapy, and 5 were administered RTP only. Both groups participated in individualized, 45-min therapy sessions occurring 3 days/week over an 8-week period. The arm, hand ability, activities of daily living, and perceptions of recovery subscales of the Stroke Impact Scale (SIS), as well as UE reaching kinematics, assessed before and after the intervention. Subjects in the RTP+Myomo group showed greater improvements on all SIS subscales, with the recovery scale reaching statistical significance (p = .03). Subjects in the RTP-only group showed a greater increase in hand velocity in the reach up task (p = .02), but no changes were observed in the range of shoulder flexion or elbow extension during reaching. None of the changes in kinematic outcome measures significantly correlated with any of the changes in SIS subscales. RTP integrating myoelectric bracing may be more beneficial than RTP only in improving self-reported function and perceptions of overall recovery. The authors observed no changes in the range of elbow extension, and no relationship between self-reported improvements and changes in reaching kinematics.     

Appropriateness of decisions as a moderator of the psychology of voice

This paper focuses on the psychology of the voice effect (the effect that people show more positive reactions when they are allowed an opportunity to voice their opinion in the decision‐making process than when they are denied such an opportunity). It is argued that it is important to ask about what decisions people are allowed voice. More specifically, results of two experiments suggest that when participation in decision making is appropriate (i.e. voice is allowed about decisions that are relatively important to participants) the voice effect is found: People's procedural judgements and other reactions are more positive following voice as opposed to no‐voice procedures. However, when participation in decision making is inappropriate (i.e. voice is allowed about decisions that are unimportant to participants) no effect or even a reversal of the voice effect is found. These people do not react differently or even react more negatively following voice as opposed to no‐voice procedures. It is concluded that these results further our insights into the psychology of procedural justice in general and voice in particular. Copyright © 2002 John Wiley & Sons, Ltd.
