The Role of Conviction in Personal Disease Risk Perceptions: What Can We Learn From Research on Attitude Strength?

Perceived risk for disease is included as a predictor of intentions and behavior in many health behavior theories. However, perceived risk is not always a strong predictor of intentions and behaviors. One reason may be suboptimal conceptualization and measurement of risk perceptions; in particular, research may not capture the conviction and certainty with which a risk perception is held. The rich and independent literature on attitudes might be leveraged to explore whether conviction is an important moderator of the effects of risk perceptions on intentions and behavior. Attitudes are more predictive of intentions when they are high in multiple aspects of attitude strength, including attitude certainty and being more accessible and stable over time. Working from the assumption that risk perceptions have a similar structure and function to attitudes, we consider whether factors known to strengthen the attitude–behavior correspondence might also strengthen the risk perception–behavior correspondence. Although by strict definition risk perceptions are not evaluations (a critical component of attitudes), the predictive validity of risk perceptions may be increased by attention to one's “conviction” or certainty of perceived risk. We also review recent strategies designed to improve risk perception measurement, including affective and experiential assessments of perceived risk and the importance of allowing people to indicate that they “don't know” their disease risk. The aim of this paper is to connect two disparate literatures – attitudes and persuasion in social psychology with risk perceptions in health psychology and decision science – in an attempt to stimulate more work on characteristics and proper measurement of risk perceptions.     

Verbal memory deficits in children with less than 750 g birth weight.

Numerous studies have documented memory deficits in very low birthweight (VLBW, < 1500 g) children, yet we know little about the nature of these memory problems. To clarify memory sequelae and examine memory deficits in relation to the degree of low birth weight, we administered the California Verbal Learning Test-Children's Version (CVLT-C) to a regional sample of 57 < 750 g birthweight children and to groups of 53 750-1499 g birthweight children and 49 term-born controls. Group comparisons revealed significant differences between the < 750 g birthweight group and term-born children on measures of list learning, delayed recall, and inaccurate recall. In addition, the percentage improvement in correct recognitions relative to long-term delayed recall was greater in the < 750 g group than in the term-born controls. Similar differences were observed between VLBW children with and without abnormal neonatal cerebral ultrasounds (high- and low-risk groups). Differences in learning rate between the VLBW and term-born groups, and between high- and low-risk VLBW children, were evident even when vocabulary skill was covaried or when children with neurosensory deficits or IQ < 80 were excluded from analysis. The findings document deficits in verbal memory in the subset of VLBW children at greatest biological risk, and suggest that acquisition processes are selectively impaired.     

Health-Related Risk Perception and Decision-Making: Lessons from the Study of Motives in Social Psychology

Much research in the decision sciences has shown that risk perception and decision-making are influenced not only by cognitive processes – such as the use of statistical 'rules of thumb'– but also by motives such as loss aversion, ambiguity aversion, and regret aversion. The field of social psychology has long been interested in a variety of motives that influence self-judgment, social perception, and interpersonal relations. These include, among others, self-enhancement, social comparison, predictability/control, favorable self-presentation, effective resource management, preparedness for bad news, goal attainment, and existential meaning. We suggest that more attention to these motives would greatly strengthen our understanding of how people think about risk and how they make decisions. In this article, we consider the influence of motives on risk perception and decision-making in the context of health outcomes. We argue that theories relating to these various motives (e.g., social comparison theory) can be greatly enhanced by testing them in the context of health-related risk perception and decision-making.     

The effect of gaze on gaze direction while looking at art

In highly controlled cuing experiments, conspecific gaze direction has powerful effects on an observer’s attention. We explored the generality of this effect by using paintings in which the gaze direction of a key character had been carefully manipulated. Our observers looked at these paintings in one of three instructional states (neutral, social, or spatial) while we monitored their eye movements. Overt orienting was much less influenced by the critical gaze direction than what the cuing literature might suggest: An analysis of the direction of saccades following the first fixation of the critical gaze showed that observers were weakly biased to orient in the direction of the gaze. Over longer periods of viewing, however, this effect disappeared for all but the social condition. This restriction of gaze as an attentional cue to a social context is consistent with the idea that the evolution of gaze direction detection is rooted in social communication.

Memory and coping with stress: The relationship between cognitive–emotional distinctiveness,memory valence,and distress

Cognitive–emotional distinctiveness (CED), the extent to which an individual separates emotions from an event in the cognitive representation of the event, was explored in four studies. CED was measured using a modified multidimensional scaling procedure. The first study found that lower levels of CED in memories of the September 11 terrorist attacks predicted greater frequency of intrusive thoughts about the attacks. The second study revealed that CED levels are higher in negative events, in comparison to positive events and that low CED levels in emotionally intense negative events are associated with a pattern of greater event-related distress. The third study replicated the findings from the previous study when examining CED levels in participants’ memories of the 2004 Presidential election. The fourth study revealed that low CED in emotionally intense negative events is associated with worse mental health. We argue that CED is an adaptive and healthy coping feature of stressful memories.     

Distinctions Between Worry and Perceived Risk in the Context of the Theory of Planned Behavior

Worry and risk perception were integrated into the theory of planned behavior (TPB) within health and non-health domains (flossing and academic coursework, respectively). Models were estimated and replicated in 2 undergraduate samples ( n s = 191 and 309), with effects of worry and risk on intentions expected to occur primarily through attitudes. Past behavior was modeled through effects on all TPB constructs and through interactions with worry and risk. Worry positively predicted intentions and attitudes (and norms in the non-health domain) for those at the lowest levels of prior behavior. Risk perceptions negatively predicted intentions and self-efficacy (and attitudes in the health context) also for those at low levels of prior behavior. Implications for further theory development are discussed.     

A Multivariate Multilevel Approach to the Modeling of Accuracy and Speed of Test Takers

Response times on test items are easily collected in modern computerized testing. When collecting both (binary) responses and (continuous) response times on test items, it is possible to measure the accuracy and speed of test takers. To study the relationships between these two constructs, the model is extended with a multivariate multilevel regression structure which allows the incorporation of covariates to explain the variance in speed and accuracy between individuals and groups of test takers. A Bayesian approach with Markov chain Monte Carlo (MCMC) computation enables straightforward estimation of all model parameters. Model-specific implementations of a Bayes factor (BF) and deviance information criterium (DIC) for model selection are proposed which are easily calculated as byproducts of the MCMC computation. Both results from simulation studies and real-data examples are given to illustrate several novel analyses possible with this modeling framework.

The response to domestic violence in a model court: some initial findings and implications

This study utilized a non-experimental design to obtain information on a full range of domestic violence incidents brought before the Quincy, Massachusetts District Court, a model court. One limitation of previous research on spouse assaults using more sophisticated designs is that the target population has been restricted to specific subgroups of cases thereby limiting subsequent discussions of policy/practice implications of the findings vis-a-vis all spouse assault cases. To address this research “shortfall”, we obtained permission from the Quincy District Court to examine all the spouse assault cases brought before the court during a 7-month period (June, 1995, through February, 1996). The findings show that in a full enforcement environment, victims took out restraining orders only against the most violent, criminally abusive men. Most men who were arrested for domestic violence had prior criminal histories for a variety of offenses. Domestic violence offenders appeared to be of two types: those with extensive and diverse criminal histories and those with little or no such involvement. However, active criminal justice intervention against domestic violence offenders appears to be primarily directed toward offenders already active in the criminal justice system. © 1998 John Wiley & Sons, Ltd.
