Positive health behaviours such as physical activity can prevent or reverse many chronic conditions, yet a majority of people fall short of leading a healthy lifestyle. Recent discoveries in ...affective science point to promising approaches to circumvent barriers to lifestyle change. Here, we present a new theoretical framework that integrates scientific knowledge about positive affect with that on implicit processes. The upward spiral theory of lifestyle change explains how positive affect can facilitate long-term adherence to positive health behaviours. The inner loop of this spiral model identifies nonconscious motives as a central mechanism of behavioural maintenance. Positive affect experienced during health behaviours increases incentive salience for cues associated with those behaviours, which in turn, implicitly guides attention and the everyday decisions to repeat those behaviours. The outer loop represents the evidence-backed claim, based on Fredrickson's broaden-and-build theory, that positive affect builds a suite of endogenous resources, which may in turn amplify the positive affect experienced during positive health behaviours and strengthen the nonconscious motives. We offer published and preliminary evidence in favour of the theory, contrast it to other dominant theories of health behaviour change, and highlight attendant implications for interventions that merit testing.

Collaborations among researchers and across disciplinary, organizational, and cultural boundaries are vital to address increasingly complex challenges and opportunities in science and society. In ...addition, unprecedented technological advances create new opportunities to capitalize on a broader range of expertise and information in scientific collaborations. Yet rapid increases in the demand for scientific collaborations have outpaced changes in the factors needed to support teams in science, such as institutional structures and policies, scientific culture, and funding opportunities. The Science of Team Science (SciTS) field arose with the goal of empirically addressing questions from funding agencies, administrators, and scientists regarding the value of team science (TS) and strategies for successfully leading, engaging in, facilitating, and supporting science teams. Closely related fields have rich histories studying teams, groups, organizations, and management and have built a body of evidence for effective teaming in contexts such as industry and the military. Yet few studies had focused on science teams. Unique contextual factors within the scientific enterprise create an imperative to study these teams in context, and provide opportunities to advance understanding of other complex forms of collaboration. This review summarizes the empirical findings from the SciTS literature, which center around five key themes: the value of TS, team composition and its influence on TS performance, formation of science teams, team processes central to effective team functioning, and institutional influences on TS. Cross-cutting issues are discussed in the context of new research opportunities to further advance SciTS evidence and better inform policies and practices for effective TS.

Background
Individual variability in response to multiple modalities of obesity treatment is well documented, yet our understanding of why some individuals respond while others do not is limited. The ...etiology of this variability is multifactorial; however, at present, we lack a comprehensive evidence base to identify which factors or combination of factors influence treatment response.
Objectives
This paper provides an overview and rationale of the Accumulating Data to Optimally Predict obesity Treatment (ADOPT) Core Measures Project, which aims to advance the understanding of individual variability in response to adult obesity treatment. This project provides an integrated model for how factors in the behavioral, biological, environmental, and psychosocial domains may influence obesity treatment responses and identify a core set of measures to be used consistently across adult weight‐loss trials. This paper provides the foundation for four companion papers that describe the core measures in detail.
Significance
The accumulation of data on factors across the four ADOPT domains can inform the design and delivery of effective, tailored obesity treatments. ADOPT provides a framework for how obesity researchers can collectively generate this evidence base and is a first step in an ongoing process that can be refined as the science advances.

Despite the abundance of research on negative intrusive thoughts, far less is known about their positive counterparts. In two studies, we explored how positive spontaneous thoughts are related to ...people’s favorite activities (i.e., their passions, Vallerand et al. in J Pers Soc Psychol 85(4):756–767. doi:

), and how passions and associated thoughts contribute to mental health. In Study 1, 170 participants reported on the valence and frequency of the spontaneous thoughts they tend to have about several activities. Harmonious and obsessive passion both predicted more frequent spontaneous thoughts, but only harmonious passion predicted thought positivity. In Study 2, 232 participants completed measures pertaining to physical activity, spontaneous thoughts, and mental health. As predicted, positivity of spontaneous thoughts about physical activity predicted frequency of physical activity. Further, positivity of spontaneous thoughts about physical activity mediated the relationship between harmonious passion and indices of mental well-being.

Objective: Prior research has documented the influence of social norms on health-related behaviors, though social norms may affect behaviors in more complex ways than have conventionally been ...modeled. The present research evaluates parent norms and teens' own attitudes as moderators of associations between perceived peer norms and diet and physical activity behaviors (both health-promoting and health-impairing) in a national sample of U.S. adolescents. Methods: Adolescent participants (N = 1,859; ages 12-17) from the 2014 Family Life, Activity, Sun, Health, and Eating study reported on the extent to which their friends eat fruits and vegetables; eat junk food or drink sugary drinks; exercise; and watch TV, play on the computer, or play electronic games most days of the week. They also reported on their own attitudes and behaviors as well as their parents' corresponding behaviors and rules. Results: Perceived peer norms were associated with teens' own health-promoting behaviors such as fruit and vegetable consumption and physical activity as well as health-impairing behaviors such as junk food consumption and sedentary habits. Teens who reported liking fruits and vegetables or physical activity or perceiving congruent descriptive parental norms demonstrated the strongest positive associations between peer norms and their own behavior. Conclusions: Perceived social norms may play a significant role in both health-impairing and health-promoting behaviors, particularly when congruent with attitudes or descriptive parental norms about those behaviors. The findings may inform interventions such as social norms marketing campaigns that aim to change perceptions of peer norms for health-promoting behavior.

The present work explores the theoretical relationship between positive spontaneous thoughts and incentive salience-a psychological property thought to energize wanting and approach motivation by ...rendering cues that are associated with enjoyment more likely to stand out to the individual when subsequently encountered in the environment (Berridge, 2007). We reasoned that positive spontaneous thoughts may at least be concomitants of incentive salience, and as such, they might likewise mediate the effect of liking on wanting. In Study 1, 103 adults recruited via Amazon's Mechanical Turk reported on key aspects of 10 everyday activities. As predicted, positive spontaneous thoughts mediated the relationship between liking an activity in the past and wanting to engage in it in the future. In Study 2, 99 undergraduate students viewed amusing and humorless cartoons and completed a thought-listing task, providing experimental evidence for the causal effect of liking on positive spontaneous thoughts. In Study 3, we tested whether positive spontaneous thoughts play an active role in energizing wanting rather than merely co-occurring with (inferred) incentive salience. In that experiment involving 80 undergraduates, participants who were led to believe that their spontaneous thoughts about a target activity were especially positive planned to devote more time to that activity over the coming week than participants who received no such information about their spontaneous thoughts. Collectively, these findings suggest that positive spontaneous thoughts may play an important role in shaping approach motivation. Broader implications and future directions in the study of positive spontaneous thoughts are discussed.

The present research evaluated the social, affective, and cognitive processes underlying sustained patterns of health behavior as articulated by the upward spiral theory of lifestyle change. ...Specifically, we tested whether positive affect experienced during physical activity changes over time in tandem with perceived social integration (PSI), and whether PSI is associated with future activity indirectly through sociality during physical activity, positive affect during physical activity, and positive spontaneous thoughts about physical activity. Adult participants (N = 226) reported daily on their PSI, physical activity behavior, and affect during physical activity for 11 weeks. Once every 2 weeks, they also reported on features of a specific bout of physical activity, including how social it was, positive affect during the activity, and positivity of spontaneous thoughts about physical activity. Multilevel modeling of daily reports over the 11 weeks revealed that as participants' PSI increased, so did their positive affect during physical activity. Further, structural equation modeling of specific reports revealed a significant indirect effect of PSI on future activity through sociality during an intervening instance of physical activity, positive affect experienced during that activity, and positive spontaneous thoughts about physical activity. The findings reported herein provide evidence consistent with the upward spiral theory of lifestyle change and reveal affective and cognitive mechanisms by which social processes may contribute to positive health behavior change and maintenance: namely, positive affect during physical activity and spontaneous thoughts about physical activity. Beyond its utility for evaluating theory, the present study may inform subsequent research aimed at developing sustainable behavior-change interventions.

Background
Within the Accumulating Data to Optimally Predict obesity Treatment (ADOPT) Core Measures Project, the psychosocial domain addresses how psychosocial processes underlie the influence of ...obesity treatment strategies on weight loss and weight maintenance. The subgroup for the psychosocial domain identified an initial list of high‐priority constructs and measures that ranged from relatively stable characteristics about the person (cognitive function, personality) to dynamic characteristics that may change over time (motivation, affect).
Objectives
This paper describes (a) how the psychosocial domain fits into the broader model of weight loss and weight maintenance as conceptualized by ADOPT; (b) the guiding principles used to select constructs and measures for recommendation; (c) the high‐priority constructs recommended for inclusion; (d) domain‐specific issues for advancing the science; and (e) recommendations for future research.
Significance
The inclusion of similar measures across trials will help to better identify how psychosocial factors mediate and moderate the weight loss and weight maintenance process, facilitate research into dynamic interactions with factors in the other ADOPT domains, and ultimately improve the design and delivery of effective interventions.

Illicit drug preparations often include more than one pharmacologically active compound. For example, cocaine and synthetic cathinones e.g., 3,4-methylenedioxypyrovalerone (MDPV) are often mixed with ...caffeine before sale. Caffeine is likely added to these preparations because it is inexpensive and legal; however, caffeine might also mimic or enhance some of the effects of cocaine or MDPV. In these studies, male Sprague-Dawley rats were trained to discriminate 10 mg/kg cocaine from saline, and the discriminative stimulus effects of cocaine, caffeine, and MDPV were evaluated alone and as binary mixtures (cocaine and caffeine, MDPV and caffeine, and cocaine and MDPV) at fixed-dose ratios of 3:1, 1:1, and 1:3 relative to the dose of each drug that produced 50% cocaine-appropriate responding. Dose-addition analyses were used to determine the nature of the drug-drug interactions for each mixture (e.g., additive, supra-additive, or subadditive). Although additive interactions were observed for most mixtures, supra-additive interactions were observed at the 50% effect level for the 1:1 mixture of cocaine and caffeine and at the 80% effect level for all three mixtures of cocaine and caffeine, as well as for the 3:1 and 1:3 mixtures of cocaine and MDPV. These results demonstrate that with respect to cocaine-like discriminative stimulus effects, caffeine can function as a substitute in drug preparations containing either cocaine or MDPV, with enhancements of cocaine-like effects possible under certain conditions. Further research is needed to determine whether similar interactions exist for other abuse-related or toxic effects of drug preparations, including cocaine, synthetic cathinones, and caffeine.
Behavior change research to promote health and prevent disease increasingly relies on a complex set of interacting characteristics across levels of influence such as biological, psychological, ...behavioral, interpersonal, and environmental. How to best develop health-related interventions that incorporate the individual, the macro-environment, and their interactions remains a challenge. This article considers a set of key dimensions that constitute what we refer to as the ecology of research across a broad context of multilevel research (MLR), spanning fundamental multilevel research (FMLR), multilevel intervention research (MLIR), and multilevel implementation science (MIS). With the goal of promoting improvements in MLIR, we describe the inherent interdependencies among aspects of research and consider how the growth and development of evidence and resources influence the cross-talk among researchers from different perspectives (e.g., disciplines and domains). We propose a framework that highlights opportunities to reduce barriers and address gaps in areas critical to generating an evidence base through MLR, MLIR, and MIS. Overall, we aim to support strategic decisions that can accelerate our understanding of ML health outcomes and interactions among factors within and across levels, with the goal of strengthening the effectiveness of ML interventions across health-related outcomes.
