Variables Associated With Adolescent Alcohol Use: A Multiethnic Comparison

Abstract

The authors examined the influence of sociodemographic variables on the frequency and intensity of alcohol use among a nationally representative sample of Black, Hispanic, and White adolescents who had participated in the 1991 National Household Survey on Drug Abuse (U.S. Department of Health and Human Services, 1993). The sample consisted of 8,756 U.S. adolescents aged 12 to 18 years. The authors found that (a) approximately 19% of the respondents had used alcohol in the last 30 days; (b) among the respondents who had used alcohol, 21% had consumed 1 or more drinks per drinking episode; and (c) there were important similarities as well as important differences in variables that promoted alcohol use among Black, Hispanic, and White adolescents.     

Death Goes to the Polls: A Meta‐Analysis of Mortality Salience Effects on Political Attitudes

Terror management theory posits that people are motivated to affirm cultural meaning systems, including political ideologies, to avoid the awareness of mortality. Accordingly, studies show that increasing mortality salience (MS) intensifies people's attitudes toward political issues and figures. However, whereas in some studies MS increases affirmation of preexisting political ideologies, be they liberal or conservative (supporting a “worldview‐defense hypothesis”), in other studies MS elicits a general shift toward conservatism, regardless of preexisting ideology (supporting a “conservative‐shift hypothesis”). The current study used meta‐analysis to assess the overall magnitude of MS effects on explicitly political attitudes and to clarify the nature of these effects by comparing effect sizes for these competing hypotheses. The overall effect of MS on political attitudes was large (r = .50). The effects of MS‐induced worldview defense (r = .35) and conservative shifting (r = .22) were significant and statistically equivalent. We discuss the conditions (e.g., contextual salience of political values) under which conservative shifting or worldview defense occurs.     

Existential function of babies: Babies as a buffer of death-related anxiety

The present study examined babies as death anxiety buffers with Chinese participants in three experiments. In Experiment 1, death-related thoughts increased college-aged participants' interest in human babies. In Experiment 2, images of newborn animals reduced the number of death-related thoughts recorded by college-aged participants. In Experiment 3, female factory workers who read news articles describing deaths of babies had pessimistic estimations of their own life expectancies. An explanation of these results is provided within a terror management theory framework, with a primary focus on how babies reinforce cultural worldviews and enhance self-esteem via the notion of symbolic immortality. Thus, the anxiety-buffering function of baby is subsumed under cultural worldviews validation and self-esteem enhancement.     

The effect of mortality salience and belief in afterlife on the manifestation of homonegativity

If derogation of out-groups serves the function of bolstering self-esteem, it is possible that this effect can be counteracted by means of existential relief. Two variables were presented in a 2 × 2 factorial to a population of primarily college students: a mortality salience (MS) variable and an afterlife variable, in which participants read “scientific” accounts that either supported or denied the existence of a literal afterlife. Homonegativity was utilised as a dependent measure of out-group derogation. In the predicted manner, mortality salience and afterlife variables interacted to predict significantly different levels of homonegativity. When participants were subconsciously primed with MS, their psychological need to derogate dissimilar others was significantly lowered if they were assured of an afterlife. These results demonstrate that the effects of MS can be attenuated by presenting existential relief through assurance of literal afterlife.     

死亡提醒效应：概念、测量及来自多领域的证据

死亡提醒效应是指由于死亡提醒而引起的世界观防御或自尊寻求。对死亡提醒效应的测量主要考察死亡提醒后,被试在世界观防御或自尊寻求上的反应。死亡提醒效应在健康、消费、司法、政治及和平领域均有所体现,并对现实生活富有启示作用。未来研究应细化世界观的概念,并借鉴本土文化中的生死观。     

When being far away is good: Exploring how mortality salience,regulatory mode,and goal progress affect judgments of meaning in life

Research indicates that death‐relevant thoughts (mortality salience) have a nuanced effect on judgments of life's meaningfulness. Thoughts of death diminish meaning in life only among people who lack or do not readily engage psychological structures that confer meaning. Building on this past research, the current research examined how an important source of meaning, long‐term goal progress, affects the ways that death‐relevant cognitions impact judgments of life's meaning. In Study 1 (N = 118), mortality salience decreased perceptions of meaning in life only among participants who were induced to feel closer to (vs. farther from) completing a long‐term goal. Study 2 (N = 259) extended these findings by demonstrating the moderating influence of individual differences in locomotion. Mortality salience again decreased perceptions of meaning in life among participants who felt closer to accomplishing a long‐term goal, but it only did so among people who do not quickly adopt new goals to pursue (i.e., those low in locomotion). The implications of these findings for better understanding how people maintain meaning in the face of existential concerns and how aspects of goal pursuit affect these processes are discussed.     

Mortality salience effects on reckless driving intentions in a motorcyclist sample: The moderating role of group riding

Campaigns against reckless driving often mention the risk of dying. Research on terror management theory indicates that death claims may backfire and foster reckless driving. Here, we studied such mortality salience effects in a motorcyclist sample. Two moderating variables, particularly interesting regarding the sample of motorcyclists, were considered: group riding (vs. riding alone) and driving‐related self‐esteem. Motorcyclists were exposed to a campaign, either highlighting mortality or not. Orthogonally, cyclists were primed with riding in a group (vs. riding alone). Driving‐related self‐esteem was assessed via a questionnaire. We predicted that reminders of riding in a group would buffer against ironic mortality effects. Supporting this hypothesis, mortality salience effects interacted with the group prime. The results indicate that death appeals are likely to backfire with cyclists riding alone rather than cyclists riding in a group, especially if motorcycling is relevant to the self.     

不确定感管理模型视角下的死亡凸显效应:争论与整合

死亡凸显效应(mortality salience effect)是恐惧管理理论(terror management theory,TMT)中一个最重要的假设,它认为与死亡有关的想法会加强个体的世界观防御。不确定感管理模型(uncertainty management model)对死亡凸显效应做出了新的解释,指出以往的研究忽视了个体的不确定感对防御行为的影响。将这种理论和TMT进行了整合与探讨,可以认为死亡凸显对个体具有双重影响,个体在思考自己的死亡后会启动双重防御体系。未来的研究,应该关注各种防御方式互相影响的关系等。     

Predictors of Self-Reported Anxiety and Panic Symptoms: An Evaluation of Anxiety Sensitivity, Suffocation Fear, Heart-Focused Anxiety, and Breath-Holding Duration

The purpose of this study was to examine the extent to which anxiety-related individual difference variables predict anxious responding when individuals experience aversive bodily sensations. Thus, we explore several psychological and behavioral predictors of response to a single 25-sec inhalation of 20% carbon dioxide-enriched air in 70 nonclinical participants. Predictor variables included anxiety sensitivity, suffocation fear, heart-focused anxiety, and breath-holding duration. Multiple regression analyses indicated that only anxiety sensitivity significantly predicted postchallenge panic symptoms, whereas both anxiety sensitivity and suffocation fear predicted postchallenge anxiety. These data are in accord with current models of panic disorder that emphasize the role of fear of fear in producing heightened anxiety and panic symptoms and help clarify specific predictors of anxiety-related responding to biological challenge.     

Terror mismanagement: evidence that mortality salience exacerbates attentional bias in social anxiety

Death anxiety is a basic fear underlying a range of psychological conditions, and has been found to increase avoidance in social anxiety. Given that attentional bias is a core feature of social anxiety, the aim of the present study was to examine the impact of mortality salience (MS) on attentional bias in social anxiety. Participants were 36 socially anxious and 37 non-socially anxious individuals, randomly allocated to a MS or control condition. An eye-tracking procedure assessed initial bias towards, and late-stage avoidance of, socially threatening facial expressions. As predicted, socially anxious participants in the MS condition demonstrated significantly more initial bias to social threat than non-socially anxious participants in the MS condition and socially anxious participants in the control condition. However, this effect was not found for late-stage avoidance of social threat. These findings suggest that reminders of death may heighten initial vigilance towards social threat.     

The Influence of Existential Threat and Tolerance Salience on Anti‐Islamic Attitudes in American Politics

Fierce public discussion has centered on anti‐Islamic attitudes and tolerance in America and the West more broadly. The present research explored whether the awareness of mortality (a common theme in politics, e.g., war/terrorism, health care, abortion, and so on) and tolerance salience might influence (1) the endorsement of anti‐Islamic attitudes in American politics and (2) political orientation. Study 1 (n = 79) was conducted in lab and Study 2 (preregistered, n = 396) replicated it online; both obtained the same results. In a neutral‐value‐prime condition, American participants reminded of mortality (vs. control topic) more strongly endorsed a Congressman’s anti‐Islamic statements about Rep. Ellison. However, in a tolerance‐value‐prime condition, participants reminded of mortality maintained their acceptance of Rep. Ellison’s beliefs and practices. Political orientation was not impacted. Implications for terror management theory (TMT), other theories of existential dynamics and motivated conservative political ideology, and both recent and contemporary American politics are discussed.     

Does the Awareness of Mortality Shape People's Openness to Violence and Conflict? An Examination of Terror Management Theory

Terror management theory (TMT) proposes that evoking death‐related thoughts (mortality salience; MS) in individuals or groups can lead to stronger worldview defence and greater support for extremist violence. In three experiments, we tested whether an MS manipulation, and associated moderators, increased support for extremist violence. In Australian university students, Study 1 found no statistically significant main or moderated effects for MS on measures of extremist violence. However, participants exposed to the MS manipulation reported increases in conservative religiosity (belief in divine power). In Study 2, the MS manipulation had no significant effect on support for extremist violence for Australian university students primed with an antiviolent extremism norm. And in young Australian Jewish people (Study 3), the MS manipulation did not increase support for violence against migrants. However, there was an increase in support for policies that act to fight against violent extremism in Iraq and Syria in those exposed to the MS manipulation. Across three studies, we find little support for the hypothesis that MS results in increased support for violent extremism. Larger more methodological sound studies are needed to address inconsistencies in the evidence surrounding TMT and the MS hypothesis, at least in regards to violence and extremism.     

Death and gratitude: Death reflection enhances gratitude

Although gratitude is important to the good life, little is known about factors that enhance gratitude. Some have suggested that traumatic events such as near-death experiences and life-threatening illnesses might enhance gratitude. If reflecting on death causes one to appreciate life as a limited resource, this might enhance gratitude. This study investigated this theory. Participants were randomly assigned to a death reflection condition, a traditional mortality salience condition, or to a control condition. Participants in the death reflection and the mortality salience conditions showed enhanced gratitude compared to individuals in the control condition, supporting the theory that becoming aware of one's mortal limitations enhances gratitude for the life that what one has.

Terror management among Chinese: Worldview defence and intergroup bias in resource allocation

Management of terror of death and its subsequent reactions has been held to be universal. However, with only a few exceptions empirical efforts have so far been focused on people from North American and European countries. Would Eastern philosophical traditions render differential management of the terror of death? The present research aimed at testing the generality of terror management in Hong Kong Chinese samples. Across four studies, we found robust and consistent mortality salience effects, which attest to the generality of terror management. As in previous studies, compared to control participants, mortality salient participants displayed a stronger ingroup bias in person evaluation (Studies 1, 3). Additionally, we found a robust mortality salience effect on intergroup bias in resource allocation (Studies 2A, 2B, 3), which has not been examined in previous terror management research.     

Fear and Anxiety in COVID-19: Preexisting Anxiety Disorders

The general population has experienced a significant elevation in fear and anxiety during COVID-19 both as a direct result of the virus but also due to measures taken to prevent it spreading, such as the need to stay inside and increase hand-washing. Lockdown has been used in many/most countries to prevent widespread infection. The advice and imposed actions are necessary to prevent the virus from spreading, but they might exacerbate the problems experienced by people with a preexisting anxiety-related disorder. The treatment of anxiety-related disorders can be provided while in quarantine. Staying at home in self-isolation does not preclude obtaining psychological treatment for anxiety-related disorders. Dealing with cognitive biases, over-estimations of threat, intolerance of uncertainty, inflated responsibility and excessive safety behavior, are useful clinical directions.
