Comparing an interdependent and dependent group contingency to increase physical activity in students during recess

Physical activity produces important physiological, mental health, academic, and cognitive benefits in children and youth. Despite these advantages, a large proportion of this population does not meet the recommended amount of physical activity. Recent studies have shown that the interdependent (IGC) and dependent (DGC) group contingencies improve physical activity; however, no comparison of the effects of these contingencies on physical activity has been conducted. We used a multielement within a concurrent multiple baseline design across three classes to compare the effectiveness of group contingencies on physical activity. Both group contingencies increased physical activity, with the IGC producing slightly higher overall levels of physical activity at the classwide and individual levels of analyses. We also compared participants' positive and negative statements and found that, regardless of the group contingency in effect, participants emitted higher levels of positive statements about the contingency when they earned the reward than when they did not, suggesting that reward delivery influenced statements more so than the group contingency arrangement. Results are discussed within the context of treatment decisions and future research.

The Value of Strength-Based Approaches in SERE and Sport Psychology

During the past 2 decades, the psychosocial landscapes of the military and elite sport have drastically changed, with the presence of stress an increasing health and safety concern. For example, in modern warfare, fighters must have the psychological capabilities to counter terrorism and undertake extended deployments in extreme environments against enemies with increasing skills for rapid development and dissemination of information and weaponry via global communication networks. In sport, performers have also reported being affected by globalization, reporting a hazardous array of stressors (e.g., roles, relationships, development issues, and organizational structure and climate) associated with preparation for and performance at major international competitions. The result of such developments is the need for leaders in both the military and sport to better understand optimal performance, and in particular the preparation of their charges, the war fighter and athlete, for the demands of their respective competition arenas. Therefore, in this narrative review we identify strength-based concepts of common interest and potential knowledge transfer in the study of psychology of excellence in the face of adversity between sport and military domains. Specifically, we highlight a value of 6 strength-based concepts for elite performance environments in sport (i.e., Olympic performance) and the military (Survival, Evasion, Resistance, and Extraction: SERE); mental toughness, positive emotion, learned optimism, resilience, posttraumatic growth, and self- and emotion regulation. In line with this discussion we highlight commonalities and knowledge transfer considerations regarding interventions in these spheres of psychological practice, the potential value of humanism and existentialism, the importance of post career and rehabilitation intervention, and readiness to change and engagement in training.     

The effectiveness of positive psychology interventions in enhancing positive behaviors and family relationships in Hong Kong: A community-based participatory research project

This paper describes a program of brief, universal, positive psychology-based interventions to increase targeted behaviors that enhance family relationships, developed and delivered to over 1500 participants using a community-based participatory approach. The cluster-randomized design combined interventions based on one of three themes (gratitude, hope, or open-mindedness) in one of two structures (intervention, or intervention with planning). The latter structure supplemented with materials and exercises derived from the Health Action Process Approach model of behavior change. Planning was more effective in increasing attitude and intention to perform behaviors, frequency of the targeted behaviors, and family health and happiness (Cohen’s ds: 0.10–0.16, p < 0.05), particularly in the theme targeting open-mindedness. Qualitative data supported effectiveness. This project was a first effort to develop a large-scale preventive psychological intervention in an understudied culture with the goal of maximizing acceptability and utilization by involving community stakeholders in every stage of the design.     

Teaching happiness at school: Non-randomised controlled mixed-methods feasibility study on the effectiveness of Personal Well-Being Lessons

The paper presents an educational initiative to develop a separate well-being curriculum for a federation of schools in south-east London. A mixed-methods study was undertaken to evaluate the feasibility of the curriculum run biweekly in Year 7 (age 11–12, N = 96). The study utilised a non-randomised repeated measures design with a control group (N = 68) using general life satisfaction, domain life satisfaction and affect balance as outcome variables. In addition, semi-structured interviews were conducted with four students, two teachers and the principal of the intervention school. The results indicated significant buffering effect of the intervention in protecting students against the decline of satisfaction with self, satisfaction with friends, positive affect and the increase in negative affect throughout the first year of middle school. The qualitative data shed light on explicit learning, psychological outcomes and challenges associated with the programme. Overall, the data indicate a positive impact of the well-being curriculum.     

Resource diary: A positive writing intervention for promoting well-being and preventing depression in adolescence

Depression in adolescence is a widespread problem and leads to extensive psychosocial impairments. For these reason, a resource diary has been developed as a four-week positive writing intervention. The aims of this intervention were to enhance well-being, to promote emotion regulation and resource realization, as well as to prevent symptoms of depression in adolescence. Seventy-seven students of 8th form were randomized either to a positive writing group (n = 38) or to a neutral writing group (n = 39). At the post-test, the positive writing group showed a lower dysphoric mood, fewer worries and less rumination in comparison with the neutral writing group. No effects on resource realization were detected. This study provides the first evidence of the beneficial effects of positive writing on indicators of well-being and depressive symptoms. In conclusion, the resource diary represents an economical intervention for preventing depression in adolescence.     

Examining explanatory mechanisms of positive and expressive writing: Towards a resource-oriented perspective

This study tested the hypothesis that benefits of positive and expressive writing accrue when the intervention matches or activates the participant’s personal resources. Students were randomly assigned to keep a newly developed resource diary (RD, n = 114), which asked the participants to write about positive experiences and personal resources, or an expressive writing diary (ED, n = 114), which asked the participants to engage with negative emotional experiences, at home on three consecutive days per week for four weeks. Participants keeping the RD perceived significantly more social support and reported a significantly better mood at post-test than participants keeping the ED. Compared to a control group (n = 81) treatment effects of both writing interventions were higher for participants with lower pre-test values of well-being and brooding as well as for participants who wrote in an ‘atmosphere of activated resources.’ It is suggested that research should move away from testing deficit-compensating hypotheses towards a stronger resource orientation.     

Awe’s effects on generosity and helping

It is unclear whether positive emotionality in general, or some specific positive emotions (e.g. other-oriented ones), but not others (e.g. self-oriented and, possibly, stimulus-oriented ones), enhance prosocial thoughts, dispositions, and behavior. We focus here on awe and argue that, although being primarily stimulus-oriented and not necessarily social in its very nature, awe should enhance prosociality for several theoretical reasons. In replicating and extending previous initial research, we found in two online experiments that the induction of awe (video clip or recall), compared to the induction of amusement or a neutral condition, leads to increased prosocial behavioral intentions of generosity (spontaneous sharing of hypothetical gains) and help of a person in need – in hypothetical everyday life situations. Awe’s effect on prosociality was independent from participants’ religiosity (in both experiments) but seemed to be clearer for those in need of such affective stimulation, i.e. less agreeable participants (Experiment 2).     

Addressing the role of personality,ability, and positive and negative affect in positive psychology interventions: Findings from a randomized intervention based on the authentic happiness theory and extensions

The present study explores the role of personality, ability, and affect in a randomized, group-based positive psychology intervention program based on Seligman’s authentic happiness theory and extensions. A total of 100 adults (M = 45.7, SD = 12.8) were randomly assigned to the 12-week intervention program (five training sessions) or a waiting list control group. The intervention consisted of basic information, group activities, and homework assignments. Participants in the intervention group demonstrated higher levels of happiness, pleasure, and engagement after completion of the program. Baseline levels of psychometric intelligence moderated the intervention effectiveness (greater effects for those higher in reasoning, vocabulary, and general intelligence). There were no effects for the big five personality traits. Finally, increases in positive affect before and after the homework assignment were associated with greater levels of happiness after the program. The relevance of these findings for the development of new programs is discussed.     

Behavioral pharmacology of the odor span task: Effects of flunitrazepam,ketamine, methamphetamine and methylphenidate

The Odor Span Task is an incrementing non‐matching‐to‐sample procedure that permits the study of behavior under the control of multiple stimuli. Rats are exposed to a series of odor stimuli and selection of new stimuli is reinforced. Successful performance thus requires remembering which stimuli have previously been presented during a given session. This procedure has been frequently used in neurobiological studies as a rodent model of working memory; however, only a few studies have examined the effects of drugs on performance in this task. The present experiments explored the behavioral pharmacology of a modified version of the Odor Span Task by determining the effects of stimulant drugs methylphenidate and methamphetamine, NMDA antagonist ketamine, and positive GABA_A modulator flunitrazepam. All four drugs produced dose‐dependent impairment of performances on the Odor Span Task, but for methylphenidate and methamphetamine, these occurred only at doses that had similar effects on performance of a simple odor discrimination. Generally, these disruptions were based on omission of responding at the effective doses. The effects of ketamine and flunitrazepam were more selective in some rats. That is, some rats tested under flunitrazepam and ketamine showed decreases in accuracy on the Odor Span Task at doses that did not affect simple discrimination performance. These selective effects indicate disruption of within‐session stimulus control. Overall, these findings support the potential of the Odor Span Task as a baseline for the behavioral pharmacological analysis of remembering.
