The effect of low social support on short-term prognosis in patients following a first myocardial infarction

The objectives of the current study were (1) to assess adjustment in patients following a first myocardial infarction (MI) at 9 months compared with 4-6 weeks post-MI, (2) to examine the availability of and satisfaction with social support over time, and (3) to determine separate baseline psychosocial predictors of recurrent cardiac events. A questionnaire assessing post-traumatic stress disorder, anxiety, depression, health complaints, and social support, was distributed to consecutive patients 4-6 weeks and 9 months post-MI. Prior to assessment at follow-up, 8 (7%) of 112 patients had dropped out, and two had died due to cardiac causes. Objective clinical measures were obtained from medical records. There was an improvement in somatic and cognitive symptoms at follow-up, but no change in symptoms of arousal, depression, and anxiety. Half of the patients were afraid of a recurrent MI. There was a significant decrease in social support between baseline and follow-up, and lower social support at baseline was associated with a 10% increased risk of recurrent cardiac events at follow-up (OR: 0.90; 95% CI: 0.84 to 0.97) adjusting for all other variables. Some patients still experienced difficulties with psychosocial adjustment 9 months post-MI despite a reduction in somatic and cognitive symptoms. Social support decreased over time, which may have serious prognostic implications; lower social support at baseline was an independent predictor of recurrent events at 9 months. An important step for future research will be to investigate how social support can be enhanced in patients at risk.     

Is sense of coherence a mediator or moderator of relationships between violence at work and stress reactions?

The relationships between exposure to violence at work, sense of coherence, and stress reactions were analysed in a large sample of the Danish workforce. The results showed that employees subjected to violence have a weaker sense of coherence than the rest of the respondents. Sense of coherence acted as a mediator and not as a moderator of relationships between exposure to violence and psychological, psychosomatic and cognitive stress reactions. The stability of the sense of coherence construct is discussed. With respect to the relation between sense of coherence and violence, preventative measures at the individual and organizational level are suggested.     

Social network as a moderator in the relation between trauma exposure and trauma reaction: a survey among UN soldiers and relief workers

Social network as a moderator between trauma exposure and post-trauma symptomatology was studied. Two samples--relief workers and UN soldiers--were assessed on trauma exposure, social network and three dependent measures related to post-trauma reactions. Regression analysis and interaction plots were used to determine the presence of interaction effects between trauma exposure and social network. All four network variables moderated the relationship between trauma exposure and post-trauma reactions among relief workers, while among UN soldiers only two such buffer effects were found. Furthermore, among UN soldiers one of these interaction effects was reversed, indicating social support to be important for those low on trauma exposure, while among relief workers support was important in the high-exposure condition. The results indicate a difference with respect to the importance of social network as a moderator between groups exposed to different kinds of war trauma. Differences in motivational systems may also exist. However, further research will have to establish this.     

Cross-validation of a minnesota multiphasic personality inventory (MMPI) subscale for the assessment of combat-related post-traumatic stress disorder

We have examined the Minnesota Multiphasic Personality Inventory (MMPI) scores of 80 carefully diagnosed veterans with post-traumatic stress disorder (PTSD) in an attempt to cross-validate the PTSD subscale and three-point MMPI code of Keane, Malloy, and Fairbank (1984). In general, although we replicated Keane and co-workers'cutoff scores, our hit rates were slightly lower than those reported originally.This research was supported in part by NIMH Grant MH-37839 to Dr. Kolb.     

Psychoanalysis and Diplomacy Part II: Large-Group Rituals

This paper focuses on the predominant repetitive activities in which a large group engages to maintain and/or repair its identity. These repetitive activities constitute large-group rituals and can be divided into two general categories: (1) rituals that occur within a society that do not involve an active relationship with a contemporary other large group; and (2) rituals that occur through and depend upon the interaction with an opposing or enemy large group, usually a neighbor. Because others are used as reservoirs for unwanted parts, both at individual and group levels, and are needed to support aspects of identity and a shared sense of sameness, the first type of ritual may also include reference to shared images of others from the large group's past. They therefore may not be strictly domestic or indigenous. Furthermore, the intensity and content of both types of rituals occur across a spectrum depending on whether a large group is at peace, in a hot conflict with an enemy group, or otherwise destabilized due to crises.     

On the Origins of Children's Compliance and Opposition: Family Context, Reinforcement, and Rules

Interactional synchrony and context dependent reinforcement are presented as similar phenomena in this discussion of children's dispositions to comply with or to oppose parental instructions. I argue that consistent and appropriate parental reactions to the full range of a child's response repertoire will establish a family context conducive to positive reinforcement of child compliance. In contrast, inconsistent parental reactions appear to create a chaotic family context conducive to the negative reinforcement of child opposition. Depending on these two forms of context, the parents and children seem to generate distinctive personal rules which outline the functional arrangements of context, behavior and reinforcement. The importance of these personal rules in helping parents and children to improve the lawfulness of family context is highlighted.     

Perceived unpleasantness and facial reactions to auditory stimuli

This study examined whether facial electromyographic (EMG) reactions differentiate between identical tone stimuli which subjects perceive as differently unpleasant. Subjects were repeatedly exposed to a 1000 Hz 75 dB tone stimulus while their facial EMG from the corrugator and zygomatic muscle regions were measured. Skin conductance and heart rate responses were also measured. The subjects rated the unpleasantness of the stimulus and based on these ratings they were divided into two groups, High and Low in perceived unpleasantness. As predicted the facial EMG activity reflected the perceived unpleasantness. That is, the High group but not the Low group reacted with an increased corrugator response. The autonomic data, on the other hand, did not differ between groups. The results are consistent with the proposition that the facial muscles function as a readout system for emotional reactions and that facial muscle activity is intimately related to the experiential level of the emotional response system.     

The development and validation of the Privacy and Data Security Concerns Scale (PDSCS)

This study describes the development and validation of the Privacy and Data Security Concerns Scale (PDSCS), designed to assess job applicants’ privacy and data security concerns. Validity evidence for the PDSCS was established with four steps including: item generation and content validation, item reduction, confirmatory factor analysis, and construct and criterion validity. Our findings supported the content and proposed factor structure of the nine‐item PDSCS. Specifically, the proposed three‐factor structure (with the subdimensions: Secure connection, inappropriate use of information, and mistrust in employer security practices) as well as a second‐order factor, (termed privacy and data security concerns) were confirmed. Additionally, evidence is presented for the criterion validity of the PDSCS and its subdimensions.     

Overgeneral autobiographical memory predicts higher prospective levels of depressive symptoms and intrusions in borderline patients

Overgeneral memory (OGM), the tendency to retrieve categories of events from autobiographical memory instead of single events, is found to be a reliable predictor for future mood disturbances and post-traumatic symptom severity. Patients with borderline personality disorder (BPD) often report co-morbid episodes of major depressive disorder (MDD) and post-traumatic stress disorder (PTSD). Therefore, we investigated whether OGM would predict depression severity and (post-traumatic) stress symptoms in BPD patients. At admission (N?=?54) and at six-month follow-up (N?≥?31), BPD patients completed the Structured Clinical Interview for DSM-IV Disorders, the Assessment of DSM-IV Personality Disorders, the Autobiographical Memory Test, the Beck Depression Inventory—2nd edition (BDI-II), and the Impact of Event Scale. OGM at baseline predicted (a) higher levels of depressive symptoms at follow-up and (b) more intrusions related to a stressful event over and above baseline levels of borderline symptoms, depressive symptoms, and intrusions, respectively. No association was found between memory specificity and event-related avoidance at follow-up. Despite previous findings suggesting that OGM in BPD is less robust than in MDD and PTSD, our results suggest that memory specificity in BPD patients may have some relevance for the course of depressive and stress symptomatology in BPD.
