Risk Factors for Attempting Suicide in Prisoners

We wished to examine determinants of suicidal behavior in prisoners. 903 male prisoners had a psychiatric interview which included various psychometric tests. Suicide attempters were compared with prisoners who had never attempted suicide. Significantly more of the attempters had a history of psychiatric disorder, substance abuse, a family history of suicidal behavior, convictions for violent crime, had exhibited aggressive behavior in jail, and had higher BGLHA aggression scores. A similar pattern of risk factors was found for prisoners with suicidal ideation. A lifetime history of attempting suicide, or of having suicidal ideation, is frequent in prisoners. Risk factors include family, developmental, aggression, personality, psychiatric, and substance abuse factors.     

When worlds collide: Engineering students encounter social aspects of production

To design effective and socially sensitive systems, engineers must be able to integrate a technology-based approach to engineering problems with concerns for social impact and the context of use. The conventional approach to engineering education is largely technology-based, and even when additional courses with a social orientation are added, engineering graduates are often not well prepared to design user- and context-sensitive systems. Using data from interviews with three engineering students who had significant exposure to a socially-oriented perspective on production systems design, this paper argues that engineering students may have difficulty integrating in their own practice the technology-based and the socially-oriented perspectives on production. To enhance engineering students' ability to create systems that integrate both perspectives, and to relieve the intense cognitive and emotional pain that can be experienced by students exposed to both perspectives but unable to reconcile them, this paper reinforces the importance of teaching students the meta skill, design. A design perspective can help students integrate varied, sometimes conflicting, perspectives, and reach beyond customer-defined constraints to consider workplace and social impact.     

Go with the flow: How children's persuasion knowledge is associated with their state of flow and emotions during advergame play

This study investigates children's persuasion knowledge towards an advergame. Based on the theory of limited capacity and the PAD dimensions of emotions (i.e. pleasure, arousal and dominance), we propose a model in which persuasion knowledge is associated with game flow, and in which game flow is subsequently related to self‐reported player emotions. To test this model, 200 respondents between 7 and 12 years old were asked to play an advergame and to complete a survey addressing self‐reported emotions, persuasion knowledge and game flow. Structural equation modelling partially confirms our model. Both managerial and ethical implications are discussed in the paper. Copyright © 2015 John Wiley & Sons, Ltd.     

Comparison of the Effects of Telephone Suicide Prevention Help by Volunteers and Professional Paid Staff: Results from Studies in the USA and Quebec,Canada

Research since the 1960s has consistently found that lay volunteers are better at helping suicidal callers than professionals. Yet, professional degrees are increasingly becoming requirements for helpline workers. In our first study, we conducted post hoc comparisons of U.S. helplines with all professional paid staff, all lay volunteers, and a mix of both, using silent monitoring and standardized assessments of 1,431 calls. The volunteer centers more often conducted risk assessments, had more empathy, were more respectful of callers, and had significantly better call outcome ratings. A second study of five Quebec suicide prevention centers used silent monitoring to compare telephone help in 1,206 calls answered by 90 volunteers and 39 paid staff. Results indicate no significant differences between the volunteers and paid employees on outcome variables. However, volunteers and paid staff with over 140 hours of call experience had significantly better outcomes. Unlike the United States, Quebec paid employees were not required to have advanced professional degrees. We conclude from these results and previous research that there is no justification for requiring that suicide prevention helpline workers be mental health professionals. In fact, the evidence to date indicates that professionals may be less effective in providing telephone help to suicidal individuals when compared to trained lay volunteers.     

Coping with type 1 diabetes through emerging adulthood: Longitudinal associations with perceived control and haemoglobin A1c

Objective: This study, which is part of a larger longitudinal study focusing on the biopsychosocial functioning of emerging adults with type 1 diabetes, examined how perceived personal control, coping and HbA_1c relate to one another over time.

Design and main outcome measures: Emerging adults with type 1 diabetes (18–30 years old) participated in a two-wave longitudinal study spanning five years (N = 164 at Time 1). At both times, patients completed questionnaires on perceived control and coping (i.e. diabetes integration, avoidant coping and passive resignation). HbA_1c values were obtained from treating clinicians. We investigated the directionality of effects using cross-lagged path analysis.

Results: Higher HbA_1c values predicted relative decreases in diabetes integration and increases in avoidant coping five years later. Feeling less in control over diabetes predicted the use of passive coping over time. Passive coping predicted a relative decrease in perceived control five years later.

Conclusion: These findings indicate that tackling poor glycaemic control is not only important to avoid medical complications but also to prevent patients from resorting to more avoidant coping strategies. Furthermore, given the longitudinal interplay between perceived control and passive coping, it is important that intervention efforts include both cognitive and behavioural components to be effective.     

Recollection,not familiarity,decreases in healthy ageing: Converging evidence from four estimation methods

Although it is generally accepted that ageing is associated with recollection impairments, there is considerable disagreement surrounding how healthy ageing influences familiarity-based recognition. One factor that might contribute to the mixed findings regarding age differences in familiarity is the estimation method used to quantify the two mnemonic processes. Here, this issue is examined by having a group of older adults (N = 39) between 40 and 81 years of age complete remember/know (RK), receiver-operating characteristic (ROC) and process dissociation (PD) recognition tests. Estimates of recollection, but not familiarity, showed a significant negative correlation with chronological age. Inconsistent with previous findings, the estimation method did not moderate the relationship between age and estimates of recollection and familiarity. In a final analysis, recollection and familiarity were estimated as latent factors in a confirmatory factor analysis that modelled the covariance between measures of free recall and recognition, and the results converged with the results from the RK, PD and ROC tasks. These results are consistent with the hypothesis that episodic memory declines in older adults are primary driven by recollection deficits, and also suggest that the estimation method plays little to no role in age-related decreases in familiarity.     

The effects of post-encoding stress on recognition memory: examining the impact of skydiving in young men and women

Prior studies have indicated that post-encoding stress can protect memories from the effects of forgetting, and this has been taken as evidence that stress facilitates memory consolidation. However, it is not known whether stress acts by directly influencing the strength of the underlying memories or whether it influences the generation process that plays a critical role in tests such as free recall. To address this issue, we examined the effects of stress produced by skydiving on recognition memory for negative and neutral pictures. Relative to a non-stress control condition, post-encoding stress in males was found to increase recognition memory for neutral pictures. However, stress was not found to improve recognition for emotional pictures, nor was it found to influence recognition memory in female participants. Additional analysis of recognition performance suggested that stress increased familiarity-based recognition rather than recollection. This study indicates that stress can improve familiarity-based recognition, thus showing that stress directly increases the strength of the underlying memories.     

The role of consumer ethical beliefs in product‐harm crises

The purpose of this paper is to investigate the consumer reaction during a product‐harm crisis by examining the interdependencies that exist among their ethical beliefs as consumers, their attributions of blame, their feelings of anger and finally their purchase intentions towards the affected company. To test the five research hypotheses, a questionnaire containing a hypothetical crisis scenario of a fictitious company was distributed to 277 consumers. Respondents were asked to read the scenario and answer questions regarding their attribution of responsibility to the company, their feelings of anger and their purchase intentions. In order to investigate consumers' ethical beliefs, a Consumer Ethics Scale was also included in the questionnaire. Structural equation modelling revealed a significant, positive correlation between attributions of blame, anger and ethical beliefs. Moreover, anger negatively affects purchase intentions, whereas the attribution of blame was not found to be significantly connected to purchase intentions. In spite of the rational connection between ethics and crisis, there is lack of research correlating these two concepts. Based on this gap in the literature, the current research attempts to connect ethical beliefs with consumer reactions and emotions during product‐harm crises.

Process demands of rejection mechanisms of recognition memory

A surge of research has been conducted to examine memory editing mechanisms that help distinguish accurate from inaccurate memories. In the present experiment, the authors examined the ability of participants to use novelty detection, recollection rejection, and plausibility judgments to reject lures presented on a recognition memory test. Participants studied a list of word pairs that were arranged in a category relationship (both words from the same category) or an unrelated relationship (both words from different categories) under full or divided attention. At test, participants were given a yes/no recognition test in which they were to respond after seeing the test items for 400 ms or 2,800 ms. Some of the test items were rearranged word pairs that were consistent with the study relationship, whereas others were inconsistent with the study relationship. The results demonstrate that the participants required full attention at study to use novelty detection, recollection rejection, and plausibility judgments to reject lures. Moreover, the results indicate that a long response deadline at test was needed for participants to use both recollection rejection and plausibility judgments to reject lures.
