Looking forward to tomorrow: The buffering effect of a daily optimism intervention

This research demonstrates the effectiveness of a brief daily self-applied optimism intervention in an adult normal population. Participants completed Life Orientation Test-Revised, Positive and Negative Affect Scale, Satisfaction with Life Scale, and Burnout Measure scales before, immediately after, and one month after the intervention. At baseline, optimism intervention group (N = 36) and control group (N = 41) were statistically similar on the variables of interest. At post-test, and also one month later, the intervention group demonstrated reduced pessimism, negative affect, and emotional exhaustion, although optimism, positive affect, and life satisfaction did not increase. Higher initial optimism increased the intervention effect for the optimism group, but not for the control group, by diminishing negative affect and emotional exhaustion, and increasing optimism. Sixty-one percent of the activities mentioned by the control group participants focused on duties and work, compared to 28% in the optimism condition. No correlations were found between initial optimism or pessimism, and the type of activities mentioned.     

Spiritual Experiences of War Veterans Who Suffer from Combat-Related Post-Traumatic Stress Disorder: A Qualitative Study

Recognition of the spiritual experiences of patients with post-traumatic stress disorder may be helpful in their rehabilitation. Accordingly, the present study has been carried out to determine the spiritual experiences of Iranian Muslim warriors who suffer from the previously mentioned disorder. In this qualitative study, 22 patients were selected using an objective-based sampling method and underwent an individual, semi-structured thorough interview. The data were analyzed using content analysis. The spiritual experiences of the participants were divided into two main categories as follows: (1) religious attitude consisting of three sub-categories known as “religious beliefs,” “religious sentiments,” and “religious behaviors” and (2) a national sensibility that includes the two sub-categories of “patriotism” and “proud” of being injured for my homeland. The analysis of the participants’ spiritual experiences showed that their specific religious orientation and feelings of nationalism assisted with their improved ability to cope with the consequences of their disorder. Therefore, it is recommended that caregivers use patients’ spiritual values to help them cope more efficiently.     

Professional burnout and work stress among Israeli dental assistants

Professional burnout and work-related stress are known problems that have been the subject of in-depth examination among dentists. Nevertheless, these issues have not been widely studied among dental assistants. The aims of this study were threefold: to confirm the structure of a Work Stress Inventory (WSI) for Dental Assistants which was originally developed for Jordanian dental assistants (factor analysis); to evaluate work stress and burnout among Israeli dental assistants and to discover the factors predicting Israeli assistants’ burnout (regression analyses). The Maslach Burnout Inventory and the WSI were distributed by mail and in person. Varimax factor analysis revealed that the items which contribute to different aspects of work stress are similar among both Jordanian and Israeli populations. Among the 299 Israeli dental assistants who completed the questionnaires, the most stressful work-related factors were income, workload, and work hazards. Eighteen percent of the participants exhibited a high to very high level of burnout. Participants exhibited a moderate level of emotional exhaustion (EE), low level of depersonalization (DP), and high level of personal accomplishment (PA). Most WSI factors were found to correlate positively with EE and DP. Linear stepwise regression analyses revealed that the best predictor of EE was the dentist?assistant relationship, followed by workload, patient type, and salary. The best predictor of DP was patient suffering followed by dentist?assistant relationship, years of professional experience, and work hazards. Professional stress and burnout among dental assistants are important factors that can possibly affect the wellbeing of both dental personnel and their patients. Further studies are necessary to better understand these factors in addition to the effects of personal relationships on burnout among dentists and their assistants.     

Status conferral in intergroup social dilemmas: behavioral antecedents and consequences of prestige and dominance

Bridging the literatures on social dilemmas, intergroup conflict, and social hierarchy, the authors systematically varied the intergroup context in which social dilemmas were embedded to investigate how costly contributions to public goods influence status conferral. They predicted that contribution behavior would have opposite effects on 2 forms of status-prestige and dominance-depending on its consequences for the self, in-group and out-group members. When the only way to benefit in-group members was by harming out-group members (Study 1), contributions increased prestige and decreased dominance, compared with free-riding. Adding the option of benefitting in-group members without harming out-group members (Study 2) decreased the prestige and increased the dominance of those who chose to benefit in-group members via intergroup competition. Finally, sharing resources with both in-group and out-group members decreased perceptions of both prestige and dominance, compared with sharing them with in-group members only (Study 3). Prestige and dominance differentially mediated the effects of contribution behavior on leader election, exclusion from the group, and choices of a group representative for an intergroup competition. Taken together, these findings show that the well-established relationship between contribution and status is moderated by both the intergroup context and the conceptualization of status.     

Effectiveness of Primiparae and Multiparae at Soothing Their Newborn Infants

To examine the effectiveness of new parents at soothing their infants, the authors filmed primiparae (20 mothers, 20 fathers) and, for comparison, multiparae (25 mothers, 25 fathers) during an interaction with their crying 2- to 3-day-old infants. Data were derived from loudness ratings of the infants' distress signals and by measuring the time it took parents to quiet their infants. In addition, specific parental behaviors were coded by microanalysis. From these data, measures of soothing effectiveness and behavioral profiles were derived. Data analyses showed that most primiparae were effective at soothing their infants' cries and that there were no parity effects on measures of soothing effectiveness. However, mothers, regardless of parity, were more effective at quieting their infants than were fathers, and there were significant differences in mothers' and fathers' caregiving behaviors. These data suggest that primiparae are effective at quickly soothing their newborns and that their skill, as measured, does not depend on parenting experience. Moreover, the data point to significant differences in mothers' and fathers' competence at quieting their newborns whether or not they are experienced at parenting.

Using the model statement to elicit verbal differences between truth tellers and liars amongst Arab interviewees: A partial replication of Leal,Vrij, Deeb,and Jupe (2018)

Leal, Vrij, Deeb, and Jupe (2018) found—with British participants—that a model statement elicited (a) more information and (b) a cue to deceit: After exposure to a model statement, liars reported significantly more peripheral information than truth tellers. We sought to replicate these findings with Arabs living in Israel. Truth tellers and liars reported a stand‐out event that they had (truth tellers) or pretended to have (liars) experienced in the last 2 years. Half of the participants were given a model statement in the second phase of the interview. Replicating Leal et al. (2018a), (a) truth tellers reported more core details than liars initially and (b) a model statement resulted in more additional core and peripheral details in the second phase of the interview. Unlike in Leal et al. (2018a), a model statement did not have a differential effect on truth tellers in the current experiment.
