Positive mental health,positive affect and suicide ideation

Background/ObjectivePositive mental health (PMH) has been shown to confer resilience against suicide ideation. However, the mechanisms underlying the positive effect of PMH on suicide ideation/behavior are largely unknown. The current study aimed to determine whether positive affect mediates the association between PMH and suicide ideation.MethodA total of 150 adult outpatients (65.3%; female; age: M(SD)=37.79(13.50), range:18–77) completed measures on PMH, positive and negative affect, as well as suicide ideation. Data were collected using self-report questionnaires. Linear hierarchical regression analysis was used to analyze the data. Positive affect was considered to mediate the association between positive mental health and suicide ideation.ResultsWhile positive affect fully mediated the significant negative association between PMH and suicide ideation, negative affect did not reveal to be a significant mediator of this relationship.ConclusionsThe protective influence of PMH against suicide ideation is due to heightened positive affect: If positive mental health translates into positive affect, then suicide ideation becomes less likely.     

Obsessive-Compulsive and Depressive Symptoms: The Role of Depressive Cognitive Styles

Obsessive-compulsive disorder (OCD) commonly co-occurs with depression, resulting in heightened severity and poorer treatment response. Research on the associations between specific obsessive-compulsive symptoms (OCS) and depressive symptoms has utilized measures that have not fully considered the relationship across OCS dimensions. Little is known about which factors explain the overlap between OCS and depressive symptoms. OCS and depressive symptoms may be related via depressive cognitive styles, such as rumination or dampening (i.e., down-regulating positive emotions). We evaluated the associations of OCS dimensions with depressive symptoms and cognitive styles. We also examined the indirect effects of rumination and dampening in the relationship between OCS and depressive symptoms. Participants (N = 250) completed questionnaires online. Greater depressive symptoms, rumination, and dampening were associated with greater levels of all OCS dimensions. Path analysis was utilized to examine a model including the direct effect of depressive symptoms on overall OCS and two indirect effects (through rumination and dampening). There was a significant indirect effect of depressive cognitive styles on the relationship between OCS and depressive symptoms, through rumination and dampening. Replication in a clinical sample and experimental manipulations may bear important implications for targeting depressive cognitive styles in treatments for OCD and depression.     

Behavioral and Nondirective Guided Self-Help for Parents of Children with Externalizing Behavior: Mediating Mechanisms in a Head-To-Head Comparison

Parent training (PT) delivered as a guided self-help intervention may be a cost- and time-effective intervention in the treatment of children with externalizing disorders. In face-to-face PT, parenting strategies have repeatedly been identified as mediating mechanisms for the decrease of children’s problem behavior. Few studies have examined possible mediating effects in guided self-help interventions for parents. The present study aimed to investigate possible mediating variables of a behaviorally oriented guided self-help program for parents of children with externalizing problems compared to a nondirective intervention in a clinical sample. A sample of 110 parents of children with externalizing disorders (80 % boys) were randomized to either a behaviorally oriented or a nondirective guided self-help program. Four putative mediating variables were examined simultaneously in a multiple mediation model using structural equation modelling. The outcomes were child symptoms of ADHD and ODD as well as child externalizing problems, assessed at posttreatment. Analyses showed a significant indirect effect for dysfunctional parental attributions in favor of the group receiving the behavioral program, and significant effects of the behavioral program on positive and negative parenting and parental self-efficacy, compared to the nondirective intervention. Our results indicate that a decrease of dysfunctional parental attributions leads to a decrease of child externalizing problems when parents take part in a behaviorally oriented guided self-help program. However, none of the putative mediating variables could explain the decrease in child externalizing behavior problems in the nondirective group. A change in dysfunctional parental attributions should be considered as a possible mediator in the context of PT.     

Traumatology Trends: A Content Analysis of Three Counseling Journals From 1994 to 2014

A content analysis of the Journal of Counseling & Development, Journal of Mental Health Counseling, and Counselor Education and Supervision from 1994 to 2014 was conducted to determine traumatology topics and trends. The frequency of trauma articles was low, and the largest category focused on sexual abuse. Few articles addressed terrorism or mass violence. Emerging topics included shared trauma and trauma supervision. Development of consistent nomenclature, trauma training, and specialized trauma journals are recommended to increase publications.     

Attempts to prime intellectual virtues for understanding of science: Failures to inspire intellectual effort

Strategies for effectively communicating scientific findings to the public are an important and growing area of study. Recognizing that some complex subjects require recipients of information to take a more active role in constructing an understanding, we sought to determine whether it was possible to increase subjects’ intellectual effort via “priming” methodologies. In particular, we asked whether subconsciously priming “intellectual virtues” (IVs), such as curiosity, perseverance, patience, and diligence might improve participants’ effort and performance on various cognitive tasks. In the first experiment, we found no significant differences in either effort or understanding between IV-primed and neutrally-primed individuals across two different priming techniques. The second experiment measured the effect of IV-priming on intellectual effort in simpler, shorter-duration puzzles and exploration activities; here, we observed an effect, but given its low strength and short duration, we do not believe that priming of IVs is a promising strategy for science communication.     

The role of chronic physical exercise and selective attention at encoding on implicit and explicit memory

Despite the evidence revealing benefits of chronic cardiovascular exercise on executive functions, little research has been conducted on long-term memory. We aimed to investigate the effect of physical exercise on implicit and explicit memory when attention was modulated at encoding in two groups of active and sedentary participants. With this purpose, attention was manipulated in a similar way in the implicit and explicit memory tasks by presenting picture outlines of two familiar objects, one in blue and the other in green, and participants were asked to pay attention only to one of them. Implicit memory was assessed through conceptual priming and explicit memory through a free recall task followed by recognition. The results did not reveal significant differences between groups in conceptual priming or free recall. However, in recognition, while both groups had similar discrimination for attended stimuli, active participants showed lower discrimination between unattended and new stimuli. These results suggested that exercise may have effects on specific cognitive processes, that is, that active participants may suppress non-relevant information better than sedentary participants, making the discrimination between unattended and new items more difficult.     

Primate vocal production and the riddle of language evolution

Trying to uncover the roots of human speech and language has been the premier motivation to study the signalling behaviour of nonhuman primates for several decades. Focussing on the question of whether we find evidence for linguistic reference in the production of nonhuman primate vocalizations, I will first discuss how the criteria used to diagnose referential signalling have changed over time, and will then turn to the paradigmatic case of semantic communication in animals, the alarm calls of vervet monkeys, Chlorocebus pygerythrus. A recent in-depth analysis of the original material revealed that, while the alarm calls could be well distinguished, calls of similar structure were also used in within- and between-group aggression. This finding is difficult to reconcile with the idea that calls denote objects in the environment. Furthermore, nonhuman primates show only minimal signs of vocal production learning, one key prerequisite for conventionalized and symbolic communication. In addition, the structure of calls in different populations or closely related species is highly conserved. In conclusion, any continuity between nonhuman primate and human communication appears to be found at the level of the processing of signals. Why and how the ancestors of our own species one day began to talk to each other continues to be an enigma. Future research should focus on changes in the neural structure supporting volitional control over vocalizations, the gene networks associated with vocal production, and the developmental processes involved in the integration of production and perception of vocalizations.     

Keeping up day-specific effects of transformational leadership: the role of followers’ emotion regulation

This diary study examines the role of day-specific transformational leadership for followers’ personal initiative. Building on Affective Events Theory, we proposed a direct effect of day-specific transformational leadership on followers’ personal initiative on the same day. Furthermore, we took a closer look at lagged effects of day-specific transformational leadership. More specifically, we hypothesized that positive effects of one day’s transformational leadership can endure until the next day for followers who apply beneficial emotion regulation strategies. We conducted a diary study over five consecutive working days among 97 employees. Two-level hierarchical linear modelling supported our hypotheses. As expected, day-specific transformational leadership positively predicted followers’ personal initiative on the same day. Furthermore, concerning the association between day-specific transformational leadership and followers’ personal initiative on the following day, there was a positive relation for followers applying beneficial emotion regulation strategies in terms of high cognitive reappraisal and low expressive suppression, respectively.     

Triadic awareness predicts partner choice in male–infant–male interactions in Barbary macaques

Social knowledge beyond one’s direct relationships is a key in successfully manoeuvring the social world. Individuals gather information on the quality of social relationships between their group companions, which has been termed triadic awareness. Evidence of the use of triadic awareness in natural contexts is limited mainly to conflict management. Here we investigated triadic awareness in wild Barbary macaques (Macaca sylvanus) in the context of bridging interactions defined as male–infant–male interactions whereby a male (initiator, holder) presents an infant to another male (receiver, non-holder) in order to initiate an affiliative interaction with that male. Analyses based on 1263 h of focal observations on ten infants of one wild social group in Morocco supported the hypothesis that males use their knowledge of the relationship between infants and other adult males when choosing a male as a partner for bridging interactions. Specifically, (i) the number of bridging interactions among holder–infant–receiver triads was positively affected by the strength of the infant–receiver relationship and (ii) when two males were available as bridging partners, a male was more likely to be chosen as the receiver the stronger his social relationship with the infant relative to the other available male. This demonstrates that non-human primates establish triadic awareness of temporary infant–male relationships and use it in a naturally occurring affiliative context. Our results contribute to the discussion about the mechanism underlying the acquisition of triadic awareness and the benefits of its usage, and lend support to hypotheses linking social complexity to the evolution of complex cognition.     

Brief training in mindfulness may normalize a blunted error-related negativity in chronically depressed patients

The error-related negativity (ERN), an evoked-potential that arises in response to the commission of errors, is an important early indicator of self-regulatory capacities. In this study we investigated whether brief mindfulness training can reverse ERN deficits in chronically depressed patients. The ERN was assessed in a sustained attention task. Chronically depressed patients (n = 59) showed significantly blunted expression of the ERN in frontocentral and frontal regions, relative to healthy controls (n = 18). Following two weeks of training, the patients (n = 24) in the mindfulness condition showed a significantly increased ERN magnitude in the frontal region, but there were no significant changes in patients who had received a resting control (n = 22). The findings suggest that brief training in mindfulness may help normalize aberrations in the ERN in chronically depressed patients, providing preliminary evidence for the responsiveness of this parameter to mental training.
