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.     

The agony of victory and thrill of defeat: Mixed emotional reactions to disappointing wins and relieving losses

Because of counterfactual comparisons, good outcomes that could have been better (i.e., disappointing wins) and bad outcomes that could have been worse (i.e., relieving losses) elicit relatively middling ratings on bipolar emotion scales. We conducted two experiments with gambles to examine whether such outcomes elicit neutral emotions, sequentially mixed emotions of positive and negative affect, or simultaneously mixed emotions. In Experiment 1, static unipolar measures of positive and negative affect revealed that disappointing wins and relieving losses elicit mixed emotions, rather than relatively neutral emotions. In Experiment 2, participants provided continuous unipolar measures of positive and negative affect by pressing one button whenever they felt good and another button whenever they felt bad. Results revealed that disappointing wins and relieving losses elicit positive and negative affect simultaneously, rather than in alternation.     

A controlled trial of cognitive-behavior therapy combined with vestibular rehabilitation in the treatment of dizziness

Dizziness is a common and often untreated symptom in the general population. The aim of this study was to investigate the effects of a combined cognitive-behavioral/vestibular rehabilitation (VR) program, using a randomized control design. A total of 29 participants were randomized to treatment consisting of psychoeducation, vestibular exercises, relaxation and cognitive interventions, or to serve as waiting list controls. Measures of dizziness-related handicap, dizziness-provoking movements, and daily diary registrations of dizziness symptoms at pre- and post-treatment showed statistically significant improvements in many domains, which translated to moderate effect sizes. These findings provide preliminary support for the combination of Cognitive-behavioral therapy (CBT) and VR methods in the treatment of dizziness.     

Being bad isn't always good: affective context moderates the attention bias toward negative information

Research has demonstrated that people automatically devote more attention to negative information than to positive information. The authors conducted 3 experiments to test whether this bias is attenuated by a person's affective context. Specifically, the authors primed participants with positive and negative information using traditional (e.g., subliminal semantic priming) and nontraditional (e.g., social interactions) means and measured the amount of attention they allocated to positive and negative information. With both event-related brain potentials (Experiment 1) and the Stroop task (Experiments 2 and 3), results suggest that the attention bias to negative information is attenuated or eliminated when positive constructs are made accessible. The implications of this result for other biases to negative information and for the self-reinforcing nature of emotional disorders are discussed.     

Quantifying Idiodynamics: A Process Approach to Personality Psychology

Rosenzweig's (1950) concept of idiodynamics is presented, and the importance of time in applied idiodynamics is stressed. Time-series analyses are proposed as one method for realizing the potential of idiodynamics for understanding and modeling individual lives. Building on this, and incorporating Cattell's (1966) notion of the data box, a process approach to personality research is proposed. This approach begins with idiodynamic analyses at the level of individual lives in an effort to identify patterns or themes, then proceeds to examine individual differences in the patterns or themes so identified. Examples of applying this process approach to personality questions are provided. These include identification of cycles in daily moods, assessing the link between each individual's moods and the events in his/her daily life, and the relation between repressive coping style and the experience of and memory for affect-charged life events. Conclusions emphasize how this approach can retain the appeal of the dynamic while maintaining the precision and rule-governed discourse afforded by quantification.     

Obscene telephone calls to children: a retrospective field study

Studied a sample of 24 Danish children selected from a larger group of 56 children who had received obscene telephone calls from a single adult offender to ascertain the psychological consequences of this form of sexual abuse. The sample is unusual in that the source of the abuse was the same for all of the children, and none of them had records of prior or concurrent abuse from other sources. Almost all children suffered significant psychological consequences from these calls, those who obeyed the caller's demands experiencing more serious consequences than those who did not. A comparison was made with the consequences suffered by an additional group of 7 children who had experienced direct physical sexual abuse by the same offender.     

Substance P is involved in terminating the hypothalamo- pituitary-adrenal axis response to acute stress through centrally located neurokinin-1 receptors

The neurokinin substance P (SP) has been previously shown to inhibit basal hypothalamo-pituitary-adrenal (HPA) axis activity. This study was designed to investigate the effects of central injection of the specific neurokinin-1 receptor antagonist RP67580 on the HPA axis response to acute restraint stress. In non-restrained rats injected with RP67580, plasma ACTH and corticosterone levels were elevated at 30 and 60 min compared to rats injected with vehicle, but there were no differences between vehicle and RP67580 groups at 4h. In restrained rats injected with vehicle, plasma ACTH and corticosterone levels were significantly elevated at 30 min and 60 min following initiation of the stress but had returned to basal levels at 4h. In restrained rats injected icv with RP67580, plasma corticosterone and ACTH levels were significantly elevated at 30 min and 60 min, with no significant differences compared to the restraint stressed vehicle-injected group. However, in the RP67580-injected group, corticosterone and ACTH levels remained significantly elevated at 4h following onset of restraint compared to those in the restraint stressed vehicle-injected group. Corticotrophin-releasing factor mRNA levels in the parvocellular subdivision of the paraventricular nucleus of the hypothalamus and POMC mRNA levels in the anterior pituitary were significantly increased in the stressed group 4h following injection with RP67580 compared to the stressed group injected with vehicle alone. These data show that endogenous SP does not inhibit the initial magnitude of the HPA axis response to restraint stress, but does act through neurokinin-1 receptors at a central level to reduce the duration of the response to stress. This suggests that SP may be an important central agent controlling the transition between acute and chronic stress.     

Susceptibility to Affect: A Comparison of Three Personality Taxonomies

This study had three major goals: to clarify the relationships between Eysenck's, Gray's, and Cloninger's personality taxonomies, to show that traits from these taxonomies predict differential sensitivities to emotional states, and to explore the relationship between sensitivity to an emotional state and how much that state is actually experienced. A factor analysis of traits from Eysenck's, Gray's, and Cloninger's personality taxonomies resulted in three factors that were named reward sensitivity, impulsivity-thrill seeking, and punishment sensitivity. These factors predicted a global measure of affect, emotional reactions to a laboratory mood induction, and self-reported affect in daily life. Generally, reward sensitivity predicted positive, but not negative emotions, whereas punishment sensitivity predicted negative, but not positive emotions. Impulsivity-thrill seeking predicted few emotions in either context. Coherence among the relationships found across methodological contexts suggests that the traits that predict emotion susceptibilities in the laboratory similarly predict emotional experience in ongoing daily life.     

Remembering experienced and reported events

Reported events are distinguished from personally experienced (autobiographical) events by being known from reports provided from some person or agency—for example, news reports. Memory for reported events has usually been ignored theoretically, or classified as ‘semantic’, though it is clearly concerned with specific, dated episodes. We discuss a number of differences between the information available to specify experienced and reported events, and the possible implications of such differences for remembering the events. A study of retrieval of the two types of events, prompted by cue words, showed that reported events take much longer time to retrieve but are dated as being equally old as experienced events. Effects of using emotion words as cues were similar for the two event types. These results suggest that reported events are forgotten (or become inaccessible) at the same rate as experienced events, but that memories are organized in such a way that reported events often have to be accessed indirectly through memories of associated autobiographical events.
