RESUMEN
Message frames are often used to communicate about invasive species due to the additional meaning they provide. They appear in calls to action like "join the battle against invasive species," "unwelcome exotics," or "Stop Aquatic Hitchhikers." However, little is known about how stakeholders respond to these message frames. This research tested five common message emphasis frames used in invasive species communication. These message frames were placed in social media advertisements about zebra mussels to determine the impact each message frame had on user online behavior. For cost-per-click (CPC), ANOVA showed effects for framing and gender. Model coefficients revealed that Hitchhiker and Protective had significantly higher CPC than Science, and that women had a higher CPC. For comments, ANOVA showed effects for framing and gender. Model coefficients revealed that no frame had a significantly different effect on comments than Science, and that women commented on posts less. For shares, ANOVA showed effects for framing. Model coefficients revealed that Hitchhiker was shared more than Science. It is important to note that neither Militaristic nor Nativist outperformed Science on any measured outcome. Coupled with ethical considerations, our results suggest the use of Nativist and Militaristic frames are not necessary to influence online behavior. Message frames without ethical issues can be used to achieve the outcomes we tested without compromising message effectiveness. Within this article, we provide background on commonly used invasive species message frames, explain our methods for testing how they impact user behavior, and suggest limitations and applications of this work.

BACKGROUND: Psychological correlates of blood lipid levels have been previously evaluated mostly in cross sectional studies. However, prospectively measured psychological factors might also predict favorable blood lipid profiles, thereby indicating a healthy mind/body interplay that is associated with less disease, better health and longer lives. METHODS: This paper examined whether longitudinal profiles of psychological well-being over 9-10 years are predictors of blood lipid profiles. Using the MIDUS (Midlife in the U.S.) biological subsample (n = 1054, aged 34 to 84, 55% female), cross-time trajectories of well-being were linked with three lipid outcomes (i.e., HDL cholesterol, triglycerides, and LDL cholesterol), measured for the first time at the 2nd wave of the study. RESULTS: Most adults showed largely stable profiles of well-being, albeit at different levels. Some showed persistently high well-being over time, while others revealed persistently low or moderate well-being. After adjusting for the effect of demographics, health behaviors, medications, and insulin resistance, adults with persistently high levels of environmental mastery and self-acceptance-two components of psychological well-being-had significantly higher levels of HDL as well as significantly lower levels of triglycerides compared to adults with persistently low levels of well-being. Converging with prior findings, no association was found between well-being and LDL cholesterol. CONCLUSIONS: Over 9-10 years, persistently high levels of psychological well-being measures predicted high HDL cholesterol and low triglycerides. These findings add longitudinal evidence to the growing body of research showing that positive psychological factors are linked with better lipoprotein profiles. A better blood lipid profile, particularly higher HDL-C, may be key in mediating how psychological well-being positively impacts health and length of life. Additional research is required to further validate this hypothesis as well as to establish potential underlying mechanisms.

Eudaimonic well-being-a sense of purpose, meaning, and engagement with life-is protective against psychopathology and predicts physical health, including lower levels of the stress hormone cortisol. Although it has been suggested that the ability to engage the neural circuitry of reward may promote well-being and mediate the relationship between well-being and health, this hypothesis has remained untested. To test this hypothesis, we had participants view positive, neutral, and negative images while fMRI data were collected. Individuals with sustained activity in the striatum and dorsolateral prefrontal cortex to positive stimuli over the course of the scan session reported greater well-being and had lower cortisol output. This suggests that sustained engagement of reward circuitry in response to positive events underlies well-being and adaptive regulation of the hypothalamic-pituitary-adrenal axis.

Objectives: This study describes a major effort to reinstate dropouts from the MIDUS longitudinal study and compare baseline characteristics among subgroups of participants to better understand predictors of retention, attrition, and reinstatement. Methods: All living dropouts were contacted, and 651 reinstated participants were interviewed in person (31.4% response rate). Age, gender, education, marital status, parental status, and physical and mental health were compared among the following groups: longitudinal sample, reinstated sample, those fielded for reinstatement who did not return, and those who dropped out at the 2nd or 3rd wave. Results: Multivariate analyses revealed that reinstated participants were younger, male, unmarried, and less educated and had children at baseline compared to longitudinal participants. Reinstatement was unsuccessful among those with poorer mental health at baseline compared to longitudinal participants. Discussion: This study informs reinstatement efforts, adjustment for attrition bias, and use of post-baseline data to examine aging consequents of early life vulnerability.

A landmark article published in the American Psychologist (Adler et al., 1994) encouraged psychologists to engage in research on socioeconomic inequality and health. Numerous contributions followed to fill in psychosocial and behavioral pathways. Specifically, we review advances on health inequalities research from a large public-use study (Midlife in the United States [MIDUS]). The Great Recession of 2007 to 2009 and its lingering effects are then reviewed to underscore widening inequality in access to education, employment, and income. Two MIDUS national samples of same-aged adults recruited 2 decades apart are then compared to assess historical changes in socioeconomic, physical health, and well-being profiles from the 1990s to postrecession. Despite historical gains in educational attainment over time, we show that indicators of socioeconomic status, health, and well-being are more compromised in the postrecession sample relative to the 1990s sample. Building on these preliminary findings, we elaborate opportunities for further inquiry by the scientific community to examine whether widening socioeconomic inequalities exacerbated by the Great Recession translate to widening health inequalities.

Psychological well-being has been linked with better health, but mostly with cross-sectional evidence. Using MIDUS, a national sample of U.S. adults (N = 4,963), longitudinal profiles of well-being were used to predict in cross-time change over a 9-10 years in self-reported health. Well-being was largely stable, although adults differed in whether they had persistently high versus persistently low or moderate levels of well-being. After adjusting for sociodemographic factors, those with persistently high well-being reported better health (subjective health, chronic conditions, symptoms, functional impairment) across time compared to those with persistently low well-being. Further, persistently high well-being was protective of improved health especially among the educationally disadvantaged. The findings underscore the importance of intervention and educational programs designed to promote well-being for greater segments of society.
RESUMEN
Midlife in the United States (MIDUS) is a national longitudinal study of health and well-being (http://midus.wisc.edu/). It was conceived by a multidisciplinary team of scholars interested in understanding aging as an integrated bio-psycho-social process, and as such it includes data collected in a wide array of research protocols using a variety of survey and non-survey instruments. The data captured by these different protocols (comprising around 20,000 variables) represent survey measures, cognitive assessments, daily stress diaries, clinical, biomarker and neuroscience data which are contained in separate flat or stacked data files with a common ID system that allows easy data merges among them. All MIDUS datasets and documentation are archived at the ICPSR (http://www.icpsr.umich.edu/) repository at the University of Michigan and are publicly available in a variety of formats and statistical packages. Special attention is given to providing clear user-friendly documentation; the study has embraced the Data Documentation Initiative (DDI) metadata standard and produces DDI-Lifecycle compliant codebooks. Potential for secondary use of MIDUS is high and actively encouraged. The study has become very popular with the research public as measured by data downloads and citation counts (see Reuse Potential below).
RESUMEN
This study investigated age differences in multiple aspects of psychological well-being among midlife and older adults in Japan (N = 482) and the United States (N = 3,032) to test the hypothesis that older Japanese adults would rate aspects of their well-being (personal growth, purpose in life, positive relations with others) more highly that older U.S. adults. Partial support was found: older adults in Japan showed higher scores on personal growth compared to midlife adults, whereas the opposite age pattern was found in the United States. However, purpose in life showed lower scores for older adults in both cultural contexts. Interpersonal well-being, as hypothesized, was rated significantly higher, relative to the overall well-being, among Japanese compared to U.S. respondents, but only among younger adults. Women in both cultures showed higher interpersonal well-being, but also greater negative affect compared with men. Suggestions for future inquiries to advance understanding of aging and well-being in distinct cultural contexts are detailed.

OBJECTIVE: This article uses data from MIDUS (Midlife in the United States), a national study of Americans (N = 7,108), to investigate factors that predict longitudinal retention. With its extensive age range (25-75 at Time 1) and long-term design (9- to 10-year survey interval), MIDUS is useful for investigating common sociodemographic and health predictors of continuing participation. METHOD: The authors conducted logistic regression analyses of baseline sociodemographic and health variables predicting retention. Select interaction terms examined the interplay between targeted variables. RESULTS: Consistent with prior research, higher retention rates were found among Whites, females, and married individuals as well as those with better health and more education. Interaction analyses further clarified that (a) health status better predicted retention among older compared to younger respondents and among women compared to men, (b) marital status better predicted retention among Whites compared to non-Whites and among women compared to men, and (c) economic status better predicted retention among those with poorer functional health status. DISCUSSION: The authors' analyses clarify that longitudinal retention varied depending on respondents' sociodemographic characteristics and their health status. The unique contribution of this article is that factors predicting nonparticipation can be offset by, or compensated for, other factors.
