COMPARISON OF ESTABLISHED AND INNOVATIVE WEIGHT-REDUCTION TREATMENT PROCEDURES1

A central component of a commonly used weight-loss procedure developed by Stuart (1967), which emphasizes situational engineering (SE), was compared to eating behavior control (EBC), a treatment employing reinforcement of changes in eating habits. A third treatment encouraged development of individuals' own applications of a model of self-control and attempted to provide effective feedback regarding progress toward weight-loss goals. This self-initiated treatment (SI) was designed to be less directive than many behavioral treatment packages and to be more realistic about the expectations of subjects and the actual eating habits of overweight and normalweight people. Following baseline, treatment lasted six weeks and followup lasted 16 weeks. While all treatments produced weight losses, EBC surpassed SE during treatment. SI losses during treatment did not differ from SE or EBC, but SI was the only group that lost weight throughout followup, indicating the possible utility of more subtle, less directive interventions than those that have often been associated with behavioral approaches. The results of SE question the applicability to clinical procedures of the external cue hypersensitivity theory of obesity (Schachter and Rodin, 1974), to which SE is closely related.     

A company-based lottery to reduce the personal driving of employees

A company-based lottery was used to reduce the number of nonessential miles employees drove their personal cars each day and thereby save gasoline. Employees were divided into an experimental and a contrast group. The experimental design involved two conditions: (a) a baseline in which no consequences were attached to driving behavior, and (b) a month-long lottery in which the experimentals were rewarded for decreasing their percentage of average miles driven per day relative to their initial baseline average. The experimentals received an ABA order of conditions while the contrast group remained in baseline. The lottery condition consisted of four weekly lotteries and one grand drawing held at the end of the month. During the lottery condition, the experimentals reduced their average daily mileage by 11.6% relative to their initial baseline (7.85 miles per employee per day) while the contrast employees increased their average mileage by 21.2%. Both groups exceeded their initial baseline averages in the return to baseline. The study was almost cost-effective because the experimentals' gas savings ($75) was within $4 of the cost of motivating them to reduce their mileage ($79).     

Toleration and prejudice-reduction: Two ways of improving intergroup relations

While a large body of social psychological research has shed light on the nature of prejudice and how to reduce it, we argue that such work does not address situations of cultural or religious outgroup beliefs and practices that are considered incompatible with one's own. The present theoretical article contrasts a prejudice-reduction approach with a toleration-based approach to consider the differences each have with regard to the attitude object they focus upon, the perceived reasonableness of the attitude, and the behavioral consequences each may lead to. In doing so, we consider the psychological processes involved in whether the negative attitude leads to negative actions. We conclude by arguing that a toleration-based approach forms an important addition to the psychological thinking about cultural diversity and intergroup relations. Collectively, the present work makes a novel contribution to the social psychological literature by stimulating theory development and raising novel questions for empirical research.     

Helping behaviour among people who use drugs: Altruism and mutual aid in a harm reduction program

People who use drugs, and particularly people experiencing addiction, are rarely afforded the opportunity to have their voices heard when it comes to drug treatment or drug policy or even when attempting to define themselves and their life experiences. Of course, there is much more to a person than one area of their behaviour. The current study seeks to capture and understand the lived experiences of people who use drugs, with a focus on their relationships and helping behaviour. We interviewed 32 participants in a harm reduction program seeking to provide understanding beyond stigmatizing and criminalizing drug narratives, by exploring their motivation and context for helping behaviours. Grounded theory methodology was used to understand the patterns of helping behaviour, along with the contexts in which help is or is not given. We particularly focus on participants' distribution of syringes and carrying medicine to reverse overdose (naloxone). Participants shared stories of altruism and mutual aid, along with barriers and disincentives to helping others. We situate these behaviours within contrasting environments of a free harm reduction program and the competitive market system of the U.S. society. Implications for practice and public policy are discussed.     

记忆的前向测试效应对老年人学习新事物的作用

为检验前置测试是否可以有效地提升老年人学习新事物的能力,参与实验的老年人被随机分为有前置测试的实验组和无前置测试的对照组,在实验1中学习了5列单词,在实验2中记忆了5列日用品,在实验3中学习了4段讲座视频。结果表明,实验组老年人对新事物的记忆成绩均高于对照组的老年人。结论认为,前置测试能够显著提升老年人学习新事物的能力,干扰降低与学习参与相结合的“加减”理论能更好地解释提升老年人记忆的前向测试效应。     

Adolescent gambling and drug use

In this study, 4516 adolescents (aged 11–16 years) completed a questionnaire examining the relationship between underage National Lottery gambling, underage scratchcard gambling, cigarette smoking, drinking alcohol and drug use. It was found that these behaviours were closely linked. Adolescent gamblers reported that they were significantly more likely to drink alcohol (particularly ‘alcopops’), smoke tobacco and take drugs compared to non-gamblers. © 1998 John Wiley & Sons, Ltd.     

Cognitive-behavioral treatment of high anger drivers

Relaxation and cognitive-relaxation interventions were compared to a no treatment control in the treatment of high anger drivers. The cognitive portion of the cognitive-relaxation condition adapted the style of Beck's cognitive therapy, particularly use of Socratic questions and behavioral experiments and tryouts, to driving anger reduction. Both interventions lowered indices of driving anger and hostile and aggressive forms of expressing driving anger and increased adaptive/constructive ways of expressing driving anger. The cognitive-relaxation intervention also lowered the frequency of risky behavior. Both interventions lowered trait anger as well. Limitations and implications for treatment and research were discussed.     

感知的和实际的友伴吸烟行为对青少年吸烟行为的影响

选取北京市一所普通中学和一所重点中学初一至高三的学生为被试,采取自由参与研究和被试自我报告、被试报告友伴、友伴自我报告吸烟行为的方式,从认知发展理论的角度出发,探讨感知的与实际的友伴吸烟行为对青少年吸烟行为的影响。结果验证了认知发展理论,即感知的友伴吸烟行为对青少年吸烟行为具有明显的影响作用,而实际的友伴吸烟行为没有明显的影响作用。研究还发现,性别和友伴关系类型对感知的与实际的友伴吸烟行为之间的差异存在明显的主效应;友伴自我报告的吸烟行为超过被试自我报告的吸烟行为。讨论揭示了研究结果对预防和干预青少年吸烟行为的意义。
