Examining the narrative roles in suicide notes

The present study examines suicide notes, using a sample of suicide notes from published corpora (N = 50), combined with a sample of recent suicide notes from a suicide website (N = 50). The present study proposes a model of differentiation in completed suicides. The characteristics of the suicide notes were analysed using a content dictionary developed by Giles in 2007, and the data subjected to smallest space analysis. Four themes of suicide completer were discovered: Egoistic Victim, Anomic Hero, Altruistic Professional and Fatalistic Revenger. The implications of these findings and the potential use in therapy work with suicide survivors and those with suicidal ideation are discussed, as well as suggestions for the direction of future research.     

Toward a social psychophysiology of vagally mediated heart rate variability: Concepts and methods in self‐regulation,emotion, and interpersonal processes

Theory and research on self‐regulation, emotional adjustment, and interpersonal processes focus increasingly on parasympathetic functioning, using measures of vagally mediated heart rate variability (vmHRV) or respiratory sinus arrhythmia (RSA). This review describes models of vmHRV in these areas, and issues in measurement and analysis. We propose a framework organizing theory and research as examining (a) vmHRV as an individual difference or a situational response, and (b) resting, reactive, or recovery levels. Evidence supports interpretation of individual differences in resting vmHRV as a broad biomarker for adaptive functioning, but its specificity and underlying mechanisms require elaboration. Individual differences in vagal reactivity (i.e., trait‐like differences in vmHRV decreases during challenge or stress) are less commonly studied in adults and results are mixed. Many stressors and challenges evoke temporary decreases in vmHRV, and in some research self‐regulatory effort evokes increases. In a smaller literature, positive interpersonal experiences and some restorative processes increase resting vmHRV, whereas depletion of self‐regulatory capacity through related effort decreases it. Greater attention to conceptual distinctions regarding vmHRV constructs and several methodological issues will strengthen future research. Importantly, researchers should exercise caution in equating vmHRV with specific psychosocial constructs, especially in the absence of converging assessments and precise experimental manipulations.     

Reappraising the link between peritraumatic dissociation and PTSD symptom severity: evidence from a longitudinal study of community violence survivors

Cross-lagged panel analysis of longitudinal data collected from young adult survivors of community violence was used to examine the relationship between recall of peritraumatic dissociation and posttraumatic stress disorder (PTSD) symptom severity. Recollections of peritraumatic dissociation assessed within days of exposure differed from recollections measured at 3- and 12-month follow-up interviews. Peritraumatic dissociation was highly correlated with PTSD symptoms within each wave of data collection. Baseline recollections of peritraumatic dissociation were not predictive of follow-up PTSD symptom severity after controlling for baseline PTSD symptom severity. This pattern of results replicates previous work demonstrating a correlation between peritraumatic dissociation and subsequent symptom severity. However, findings are not consistent with the prevailing view that peritraumatic dissociation leads to increased PTSD symptom severity.     

Putting the cart before the horse: the benefits of arbitrating before mediating

The authors examined the impact of 2 hybrid dispute resolution procedures (mediation-arbitration [med-arb] and arbitration-mediation [arb-med]) and 3 disputant dyadic structures (individual vs. individual, individual vs. team, and team vs. team) on various dispute outcomes. Consistent with W. H. Ross and D. E. Conlon (2000), the authors found that disputants in the arb-med procedure (a) settled in the mediation phase of their procedure more frequently and (b) achieved settlements of higher joint benefit than did disputants in the med-arb procedure. These results suggest that arb-med may be a dispute resolution procedure with broader applicability than originally imagined.     

Mental simulation inflates performance estimates for physical abilities

In five experiments, we examined how mental simulation of physical activities affected estimates of one's ability to perform the same activities. In Experiment 1, participants who simulated lifting aheavy object estimated that they could lift more weight than did participants who did not perform the simulation. In Experiment 2A, the frequency with which participants performed the simulation exercises was manipulated. In Experiments 2B and 2C, we manipulated the amount of weight that people simulated lifting in order to address potential alternative explanations of the inflation effect. In Experiment 3, mental simulations were manipulated within subjects. In all the experiments, the simulated events showed inflated estimates, as compared with nonsimulated events. These results were interpreted in the context of the misattribution-of-familiarity account of imagination inflation.     

Measuring self-efficacy among drug-involved probationers

Self-efficacy has been shown to be related to outcomes from interventions for alcohol and tobacco abuse but relatively little attention has been focused on it in evaluations of treatment for illicit drug abuse. Almost no research has examined offenders involved with drugs. The current study, therefore, adapted the Alcohol Abstinence Self-efficacy Scale of DiClemente, Carbonari, Montgomery, and Hughes and administered it to 250 probationers mandated to 6 months of residential treatment. With some modifications, confirmatory factory models replicated four previously reported dimensions, e.g., Negative Affect, Social/Positive, Physical and Other Concerns, Cravings and Urges. Findings also indicated high construct validity for the Alcohol Abstinence Self-efficacy Scale as adapted here. Studies are needed to examine the use of self-efficacy as a prospective measure of treatment progress and to explore its association with outcomes from corrections-based treatment.     

Age and emotional response to the Northridge earthquake: a longitudinal analysis

Cross-sectional studies have found older adults to have lower levels of emotional distress after natural disasters. The maturation hypothesis suggests that older adults are less reactive to stress events, whereas the inoculation hypothesis argues that prior experience with disaster is protective. One hundred and sixty-six adults aged 30 to 102 were interviewed regarding the 1994 Northridge earthquake. Longitudinal data were available on depressed mood before and after the earthquake. The maturation hypothesis was generally not supported. The young-old were least depressed; however, this age difference was present prior to the earthquake. The old-old showed lowest levels of earthquake-specific rumination, but age did not buffer the relationship between damage exposure and rumination. The inoculation hypothesis was supported for depressed mood. Prior earthquake experience was related to lower postearthquake depression scores.
