Meta-analysis of the relationship between risk perception and health behavior: the example of vaccination.

Abstract: Background: Risk perceptions are central to many health behavior theories. However, the relationship between risk perceptions and behavior, muddied by instances of inappropriate assessment and analysis, often looks weak. Method: A meta-analysis of eligible studies assessing the bivariate association between adult vaccination and perceived likelihood, susceptibility, or severity was conducted. Results: Thirty-four studies met inclusion criteria (N 15,988). Risk likelihood (pooled r .26), susceptibility (pooled r .24), and severity (pooled r .16) significantly predicted vaccination behavior. The risk perception behavior relationship was larger for studies that were prospective, had higher quality risk measures, or had unskewed risk or behavior measures. Conclusions: The consistent relationships between risk perceptions and behavior, larger than suggested by prior meta-analyses, suggest that risk perceptions are rightly placed as core concepts in theories of health behavior.

Perceived Discrimination and the Adjustment of African American Youths: A Five-Year Longitudinal Analysis With Contextual Moderation Effects

Abstract: Longitudinal links between perceived racial discrimination and later conduct problems and depressive symptoms were examined among 714 African American adolescents who were 10-12 years old at recruitment. Data were gathered 3 times over a 5-year period. Hypotheses were tested via latent curve modeling and multiple-group latent growth modeling. Increases in perceived discrimination were associated with increased conduct problems and depressive symptoms. This association was weaker when youths received nurturant-involved parenting, affiliated with prosocial friends, and performed well academically. For conduct problems, the association was stronger for boys than for girls; for depressive symptoms, no gender differences emerged. The findings thus identify contextual variables that moderate the contribution of perceived discrimination to African American youths' adjustment.

Reasoned action and social reaction: Willingness and intention as independent predictors of health risk.

Abstract: Three studies are described that assess elements of a new model of adolescent health-risk behavior, the prototype/willingness (P/W) model (F. X. Gibbons & M. Gerrard, 1995, 1997). The 1st analysis examined whether a central element of the prototype model, behavioral willingness, adds significantly to behavioral expectation in predicting adolescents' smoking behavior. The 2nd set of analyses used structural-equation-modeling procedures to provide the 1st test of the complete model in predicting college students' pregnancy-risk behavior. Finally, the 3rd study used confirmatory factor analysis to assess the independence of elements of the model from similar elements in other health behavior models. Results of the 3 studies provided support for the prototype model and, in particular, for 2 of its primary contentions: (a) that much adolescent health-risk behavior is not planned and (b) that willingness and intention are related but independent constructs, each of which can be an antecedent to risk behavior.

Predicting young adults' health risk behavior.

Abstract: A prototype model of risk behavior is described and was tested in a longitudinal study of 679 college students, beginning at the start of their freshman year. Perceptions of the prototype associated with 4 health risk behaviors (smoking, drinking, reckless driving, and ineffective contraception) were assessed along with self-reports of the same behaviors. Results indicated that prototype perception was related to risk behavior in both a reactive and a prospective manner. That is, perceptions changed as a function of change in behavior, and perceptions predicted those behavior changes as well. This prospective relation was moderated by social comparison, as the link between perception and behavior change was stronger among persons who reported frequently engaging in social comparison.

Subjective well-being: Three decades of progress

Abstract: W Wilson's (1967) review of the area of subjective well-being (SWB) advanced several conclusions regarding those who report high levels of "happiness" A number of his conclusions have been overturned: youth and modest aspirations no longer are seen as prerequisites of SWB E Diener's (1984) review placed greater emphasis on theories that stressed psychological factors In the current article, the authors review current evidence for Wilson's conclusions and discuss modern theories of SWB that stress dispositional influences, adaptation, goals, and coping strategies The next steps in the evolution of the field are to comprehend the interaction of psychological factors with life circumstances in producing SWB, to understand the causal pathways leading to happiness, understand the processes underlying adaptation to events, and develop theories that explain why certain variables differentially influence the different components of SWB (life satisfaction, pleasant affect, and unpleasant affect) In 1967, Warner Wilson presented a broad review of subjective well-being (SWB) research entitled, "Correlates of Avowed Happiness" Based on the limited data available at that time, Wilson concluded that the happy person is a "young, healthy, welleducated, well-paid, extroverted, optimistic, worry-free, religious, married person with high self-esteem, job morale, modest aspirations, of either sex and of a wide range of intelligence" (p 294) In the three decades since Wilson's review, investigations into SWB have evolved Although researchers now know a great deal more about the correlates of SWB, they are less interested in simply describing the demographic characteristics that correlate with it Instead, they focus their effort on understanding the processes that underlie happiness This trend represents a greater recognition of the central role played by people's goals, coping efforts, and dispositions In this article, we review research on several major theoretical approaches to well-being and then indicate how these theories clarify the findings on demographic correlates of SWB Throughout the review we suggest four directions that researchers should pursue in the decades ahead These are by no means the only questions left to answer, but we believe they are the most interesting issues left to resolve First, the causal direction of the correlates of happiness must be examined through more sophisticated methodologies Although the causal priority of demographic factors such as marriage and income is intuitively appealing, it is by no means certain Second, researchers must focus greater attention on the interaction between internal factors (such as personality traits) and external circumstances As we shall see, demographic factors have surprisingly small effects on SWB, but these effects may depend on the personalities of those individuals being studied Thus, future research must take Person X Situation interactions into account Third, researchers must strive to understand the processes underlying adaptation Considerable adaptation to both good and bad circumstances often occurs, yet the processes responsible for these effects are poorly understood Research that examines how habituation, coping strategies, and changing goals influence adaptation will shed much light on the processes responsible for SWB Finally, theories must be refined to make specific predictions about how input variables differentially influence the components of SWB In the past, many researchers have treated SWB as a monolithic entity, but it is now clear that there are separable components that exhibit unique patterns of relations with different variables In each section of this article we discuss progress and opportunities in these four areas

Risk as Feelings

Abstract: Virtually all current theories of choice under risk or uncertainty are cognitive and consequentialist. They assume that people assess the desirability and likelihood of possible outcomes of choice alternatives and integrate this information through some type of expectation-based calculus to arrive at decision. The authors propose an alternative theoretical perspective, the risk-as-feelings hypothesis, that highlights the role of affect experienced at the moment of decision making. Drawing on research from clinical, physiological, and other subfield of psychology, they show that emotional reactions to risky situations often drive behavior. The risk-as-feelings hypothesis is shown to explain a wide range of phenomena that have resisted interpretation in cognitive-consequentialist terms.

Risk as feelings.

Abstract: Virtually all current theories of choice under risk or uncertainty are cognitive and consequentialist. They assume that people assess the desirability and likelihood of possible outcomes of choice alternatives and integrate this information through some type of expectation-based calculus to arrive at a decision. The authors propose an alternative theoretical perspective, the risk-as-feelings hypothesis, that highlights the role of affect experienced at the moment of decision making. Drawing on research from clinical, physiological, and other subfields of psychology, they show that emotional reactions to risky situations often diverge from cognitive assessments of those risks. When such divergence occurs, emotional reactions often drive behavior. The risk-as-feelings hypothesis is shown to explain a wide range of phenomena that have resisted interpretation in cognitive-consequentialist terms.

ASSESSING "NEIGHBORHOOD EFFECTS": Social Processes and New Directions in Research

Abstract: ▪ Abstract This paper assesses and synthesizes the cumulative results of a new “neighborhood-effects” literature that examines social processes related to problem behaviors and health-related outcomes. Our review identified over 40 relevant studies published in peer-reviewed journals from the mid-1990s to 2001, the take-off point for an increasing level of interest in neighborhood effects. Moving beyond traditional characteristics such as concentrated poverty, we evaluate the salience of social-interactional and institutional mechanisms hypothesized to account for neighborhood-level variations in a variety of phenomena (e.g., delinquency, violence, depression, high-risk behavior), especially among adolescents. We highlight neighborhood ties, social control, mutual trust, institutional resources, disorder, and routine activity patterns. We also discuss a set of thorny methodological problems that plague the study of neighborhood effects, with special attention to selection bias. We conclude with promising ...
