Predictors of Smoking Status After Eight Years: The Interaction of Stages of Change and Addiction Variables

Abstract

With a smoking rate of 30% of the population Switzerland has one of the highest rates of all industrialised countries. Changes in smoking status over eight years are examined by analysing the course of non-smokers, former smokers and current smokers between 1987 and 1995. Stages of change and addiction variables, as well as their interaction, are analysed for 1987 as predictors of smoking status in 1995.A sample of 953 non-smokers and former and current smokers was interviewed in 1987 and followed up in 1995. Between 1987 and 1995 every fifth non-smoker (20.9%) began smoking. The higher one is in the stage hierarchy the higher the probability of forward than of backward movement. Within the stages of change the likelihood of cessation is moderated by addiction variables. Thus, in the case of contemplating smokers in 1987, the more cigarettes they smoked daily at that time the less likely they were to be former smokers by 1995, but for preparating smokers who had already made an attempt to quit the converse holds - the more they smoked in 1987, the more likely they were to be non-smokers eight years later. The same holds for former smokers in 1987: former moderate smokers then were more likely to relapse than former heavy smokers. The implications for prevention and intervention are discussed.     

Birth Order Position and Prosocial Tendencies

This study investigated the relationship between psychological birth order position and different types and levels of prosocial tendencies. An ex postfacto, between-family research design was used. Data on prosocial tendencies were obtained from 888 college students (females = 80.4%, mean age = 20.94 yrs, SD = 2.83; males = 19.6%, mean age = 21.62 yrs, SD = 2.44). Participants completed a biographical questionnaire as well as the Prosocial Tendencies Measure (Carlo & Randall, 2002). Data were analysed to compare and contrast prosocial tendencies between demographics using parametric ANOVAs, t tests and the Mann-Whitney Test. Significant differences in prosocial tendency scores were only found between middle-borns and last-borns on altruism, with middle-borns scoring significantly higher in prosocial tendencies than last-borns. There is no evidence to suggest that a definitive link between prosocial tendencies and birth order exists in this study.     

Improving responding to questioning using a brief retrieval training

This research examined the effect of a brief training procedure for enhancing responding to questions about witnessed events. The training was based in research on metacognition and memory, and emphasized: attending to questions, searching for multiple responses, and weighing confidence in and considering the source of responses. In the main study, adult participants viewed a video of a burglary and after a 25 min delay half received the training. All participants were then asked answerable and unanswerable questions about the video. The training resulted in fewer errors and more rejections to unanswerable questions. Analysis of response diagnosticity indicated that responses made by the trained group were more likely to be correct responses to answerable questions. A second study showed that these findings were not due to awareness of the presence of unanswerable questions. The procedure has potential as a supplement when questioning is pursued.     

Hearing Impairment, Coping Strategies, and Anxiety Sensitivity

The aim was to study coping strategies among hearing-impaired individuals by using a validated coping instrument—The Ways of Coping Questionnaire (WOCQ; S. Folkman & R. Lazarus, 1988)—and to relate the use of coping with anxiety sensitivity and experience of hearing impairment. A questionnaire booklet was sent out to the members of the local branch of the Swedish Hard of Hearing Association. Ninety-four members responded to the questionnaire, yielding a 53% response rate. Primary outcome measures were the WOCQ, the Anxiety Sensitivity Index, and visual analogue scale rating of discomfort from hearing impairment. Repeated measures analysis of WOCQ subscales showed that the participants used planful problem solving and self-controlling coping strategies whereas escape/avoidance responses were less frequently used than the other coping strategies. Anxiety sensitivity was associated with escape/avoidance coping (r = .63, p < .0001). In conclusion, hearing-impaired individuals do not use escape/avoidance coping more than other coping strategies. However, escape/avoidance coping is associated with anxiety sensitivity, suggesting that sensitivity to anxiety sensations is an important associated factor. Coping strategies were not associated with discomfort from hearing impairment in any meaningful way.     

Terrorism as Collective Communication: The Collective Communication Model of Terrorism (CCMT)

This paper proposes that the psychological and behavioral effects of terrorist threat can be understood as a collective communication process that occurs between terrorists and their potential victims. Based on classic communication theory, terrorists are regarded as the senders of a specific collective message (such as ‘stop oppressing our culture’); a terrorist incident as the collective message itself (through its performance, modality and targets); and the potential victims as its collective receivers (who interpret the intention of the attack as a function of their pre-existing attributes, such as traits or salient social identities). The perception of terrorism as a dynamic and interactive process between collective senders, messages and receivers opens new theoretical perspectives regarding whether (a) terrorism can be successful in reaching its collective aim; (b) if it is interpreted as rational or irrational; and (c) how to counteract the vicious, cyclical relationship between terrorism and counter-terrorism. Previous findings on the psychology of terrorism can be organized within this theoretical framework, and the psychological impact of varying attributes of the perpetrators (senders), incident (message), and the reactions of the potential victims (receivers) systematically investigated. A series of self-conducted studies are also reviewed and found to provide direct support for the collective communication model of terrorism.     

Episodic Learner Modeling

Modeling the learner is a central aspect of intelligent tutoring systems and knowledge-based help systems that support learners in complex problem-solving domains. In this article, the episodic learner model ELM is introduced as a hybrid system that analyses novices' solutions to programming tasks based on both rule-based and case-based reasoning. ELM behaves like to a human tutor. Initially, ELM is able to analyze problem solutions based only on its domain knowledge. With increasing knowledge about a particular learner captured in a dynamic episodic case base, it adapts to the learner's individual problem-solving behavior. Two simulation studies were performed to validate the system. The first study shows that the system can learn which rules are applied successfully to diagnose code produced by programmers and that using this information reduces the computational effort of diagnoses. Using information from the episodic learner model additionally speeds up the diagnostic process. The second study shows that ELM is able to predict individual solutions. Finally, correspondences and differences to related systems are discussed.
