Longitudinal associations between people's cessation-related experiences and their satisfaction with cessation

We sought to determine whether different social, psychological, emotional, and physiological experiences associated with quitting smoking related to people's satisfaction with cessation systematically, and whether the strength of the relations changes at different points during the cessation process and for different people (e.g., optimists). Using data from smokers enrolled in a cessation program, we used mixed models to assess the average longitudinal relation between people's experiences and satisfaction measured at seven time points and whether the relations were moderated by key variables. Eight of nine experiences were related to people's satisfaction (ps < 0.05) and the models accounted for 39–44% of the within-person variance in satisfaction. Current smoking behavior was more strongly related to people's satisfaction during their early efforts to quit, whereas some experiences (e.g., feedback from others) had a stronger relation with satisfaction during people's later efforts to quit or maintain abstinence (ps < 0.05). Individual differences in optimism and prior cessation experience moderated some of the relations (ps < 0.05). The findings mark the first evidence of factors that might influence how people determine their satisfaction with smoking cessation. The implications for tailoring interventions and potentially increasing the likelihood that people maintain abstinence are discussed.     

The effects of message framing and ethnic targeting on mammography use among low-income women.

The authors examined the effects that differently framed and targeted health messages have on persuading low-income women to obtain screening mammograms. The authors recruited 752 women over 40 years of age from community health clinics and public housing developments and assigned the women randomly to view videos that were either gain or loss framed and either targeted specifically to their ethnic groups or multicultural. Loss-framed, multicultural messages were most persuasive. The advantage of loss-framed, multicultural messages was especially apparent for Anglo women and Latinas but not for African American women. These effects were stronger after 6 months than after 12 months.     

Color and intensity discrimination in <Emphasis Type="Italic">Xenopus laevis</Emphasis> tadpoles

Investigations into the physiology of Xenopus laevis have the potential to greatly accelerate biomedical research, especially concerning neural plasticity and sensory systems, but are limited by the lack of available information on behavioral learning in this species. Here, we attempt to lay the foundations for a behavioral assay in Xenopus that can be used in conjunction with biological manipulations. We tested cohorts of Xenopus tadpoles across four light-mediated active-avoidance experiments, using either wavelength or intensity as the salient discriminative cue. In the wavelength task, we determine a baseline learning rate and characterize retention of learning, identifying active extinction effects as far more potent than the passage of time in the loss of behavior. In the intensity task, we examine the effects of varying differences between the discriminative stimuli on acquisition and extinction and identify a critical range of intensity differences where learning changes. The results of our experiments demonstrate that Xenopus is a tractable model organism for cognitive research and can learn a variety of associative tasks in the laboratory settings. These data reveal new aspects of the Xenopus larval visual processing system and facilitate future research between cognitive methods and biological/chemical manipulations to study mechanisms of brain structure and function.     

The interplay between relationship effectiveness,life stress,and sleep: A prospective study

Research has shown that greater stress responses predict worse sleep and that the quality of one's current romantic relationship predicts one's sleep. Despite these established links, research has not examined connections between ongoing patterns of interpersonal experiences and competencies (relationship effectiveness) and stress exposure on sleep. Participants in the Minnesota Longitudinal Study of Risk and Adaptation (MLSRA) completed measures assessing relationship effectiveness and stress exposure at ages 23 and 32 years, as well as sleep quality/duration at age 37 years. Analyses demonstrate that relationship effectiveness at age 23 years positively predicts sleep quality—but not sleep duration—at age 37 years via reduced stress exposure at age 32 years. These findings highlight the effects of relationship effectiveness and stress exposure across early to middle adulthood on sleep.     

Absolute and Relative Biases in Estimations of Personal Risk1

Two studies examined the accuracy of personal risk estimates, as determined by comparing mean estimates made by college students with population statistics for college-educated individuals. Study 1 suggested that optimistic biases (the tendency for people to think they are less at risk than the average person) arise more because people overestimating the average person's risk than because they underestimate their own risk. In Study 2, subjects rated their risk after being presented with risk statistics that were 150%, 100%, or 50% of the true values. Subjects' estimates decreased with decreases in the comparison statistics, as if subjects attempted to preserve their “below-average” status, but they changed less than did the statistics and were actually pessimistic in comparison to the 50% values. Implications for interventions designed to influence risk perceptions are discussed.     

Designing work environments to influence productivity

Features of the work environment can be designed to contain cues for performance standards, thereby influencing productivity on the job. This paper explores the importance of normative information for motivation and how it can be designed into the workplace in order to promote more efficient job behaviors.The author gratefully acknowledges the helpful comments of Terence R. Mitchell and J.H. Kerr Inkson on an earlier draft of this paper.     

Health Message Framing: Moderators,Mediators, and Mysteries

Health message framing is an important aspect of health communication. Over the past 20 years, researchers have sought to identify the contexts in which gain‐framed and loss‐framed health messages are most likely to motivate healthy behavior. Two major approaches have emerged: One approach focusing on matching the frame of the message to how people perceive the risks and uncertainties of the advocated health behavior and the other approach focusing on matching the frame of the message to the motivational orientation of the recipient. In this review, we describe these two major approaches to health message framing, identify the most likely psychological mediators that explain why these approaches motivate behavior, suggest a way to integrate these two approaches, and outline several key future directions for both basic and applied research in health message framing.     

“How Many Partners Is Too Many?” Shaping Perceptions of Personal Vulnerability1

The effectiveness of interventions that directly inform people of the risks posed by their own behavior is frequently undermined by people's ability to defend themselves against unwanted information. In response to this difficulty, an alternative approach to shaping people's perceptions of personal vulnerability in which people remained unaware of the intervention was tested. As part of a survey on sexual issues, college undergraduates reported the total number of sexual partners they had had on a response scale that systematically framed their sexual behavior as being either above average or below average. Participants in the 2 conditions reported the same absolute number of sexual partners. However, those who received a response scale that implied they had had more partners than the average student reported greater concern about their sexual behavior than did those who received a scale that implied they had had fewer partners than average. The implications of this approach for influencing perceptions of personal risk are discussed.     

Business students' evaluation of their internships

An 8-item evaluation of a business internship was completed by 363 junior and senior undergraduates. Students agreed or strongly agreed that the internship met the following goals and criteria of the for-credit course: adequacy of orientation, clarity of expectations, helpfulness of supervision, adequacy of feedback, application of business education, development of new knowledge and skills beneficial to career exploration, value of the placement and recommendation of employer for other interns. The importance of outcome assessment is discussed within the context of internship programs.     

Evolution of the biopsychosocial model: prospects and challenges for health psychology.

Although advances have been made in specifying connections between biological, psychological, and social processes, the full potential of the biopsychosocial model for health psychology remains untapped. In this article, 4 areas that need to be addressed to ensure the continued evolution of the biopsychosocial model are identified and a series of recommendations concerning initiatives directed at research, training, practice and intervention, and policy are delineated. These recommendations emphasize the need to better understand and utilize linkages among biological, psychological, social, and macrocultural variables. Activities that facilitate the adoption of a multisystem, multilevel, and multivariate orientation among scientists, practitioners, and policymakers will most effectively lead to the kinds of transdisciplinary contributions envisioned by the biopsychosocial perspective.
