健康行为改变中的社会认知因素：HAPA模型述评

HAPA是健康行为领域研究的新取向。认为改变健康行为需要两个分离的过程:动机和意志。首先,基于自我信念的基础上形成改变的意图;随意,行为改变才会被计划、引发并维持。HAPA认为,动机阶段引起行为意图,而意志阶段则产生实际行为。以自我效能为代表的社会认知因素在两个阶段起重要作用,对于健康行为的采纳、引发和维持的产生重要的预测作用。

The role of risk perception and efficacy cognitions in the prediction of HIV-related preventive behavior and condom use

Abstract

Based on empirical findings on the central model variables of the Protection Motivation Theory, the influence of perceived susceptibility, perceived severity of the threat of AIDS, communicative and sexual self-efficacy, and outcome expectancy on various aspects of HIV-preventive behavior was examined. The study was based on a sample of 468 heterosexual adults between the ages of 20 and 45 years. The data were obtained by means of questionnaires filled out at various vacation sites that draw mass tourism or in the subjects' home town. The most significant predictor of behavior was found to be self-efficacy expectancy as regards assertiveness and use of HIV-related preventive measures. A high communicative self-efficacy expectancy, on the other hand, is associated with a higher level of risk behavior among certain subgroups and under certain behavioral aspects. This confirms the necessity of acknowledging the different forms of self-efficacy expectancy in sexual interactions. Perceived personal threat is also associated with risk behavior with respect to certain behavioral operationalizations. From this it can be concluded that one's own behavior is used as the basis for appraising one's susceptibility. The results also show that distinctions must be made when analyzing HIV-related risk behavior. In particular, a difference must be made between absolute behavior (degree of the risk behavior) and relative behavior (change - especially reduction - in risk behavior due to the danger of AIDS).     

From health beliefs to self-regulation: Theoretical advances in the psychology of action control

Abstract

The paper reviews the theoretical concepts included in a range of social cognitive models which have identified psychological antecedents of individual motivation and behaviour. Areas of correspondence are noted and core constructs (derived primarily from the theory of planned behaviour and social cognitive theory) are identified. The role of intention formation, self-efficacy beliefs, attitudes, normative beliefs and self-representations are highlighted and it is argued that these constructs provide a useful framework for modelling the psychological prerequisites of health behaviour. Acknowledging that intentions do not translate into action automatically, recent advances in our understanding of the ways in which prior planning and rehearsal can enhance individual control of action and facilitate the routinisation of behaviour are considered. The importance of engaging in preparatory behaviours for the achievement of many health goals is discussed and the processes by which goals are prioritised, including their links to self-representations, are explored. The implications of social cognitive and self-regulatory theories for the cognitive assessment of individual readiness for action and for intervention design in health-related settings are highlighted.     

Predicting adolescent health complaints by personality and Behaviors

Abstract

In a sample of 97 male adolescents, individual differences in health complaints were predicted by personality traits and by self-reported health/risk behaviors. Anxiety and loneliness were measured at Times 1 and 2, and health locus of control, various behaviors and health complaints were assessed at the end of the two-year study. A causal model was specified, employing anxiety and loneliness as distal predictors, health locus of control and behaviors as proximal predictors of health complaints. It turned out that anxiety was the most powerful single predictor, and that loneliness exerted a direct effect on health locus of control and behaviors and an indirect effect on health complaints. Risk behavior as well as health behavior were related to complaints. Social integration facilitated not only health behavior but also risk behavior.     

我国民众对SARS信息的风险认知及心理行为

采用分层抽样的调查方法,对全国17个城市的4231名市民进行了SARS疫情中风险认知特征和心理行为的研究。结果发现：（1）负性信息,包括患病信息和与自身关系密切的信息,更易引起民众的高风险认知; 正性信息,包括治愈信息和政府防范措施的信息,能降低个体风险认知水平。（2）我国民众5月中旬风险认知因素空间位置分析结果表明, SARS病因处于不熟悉和难以控制一端,“愈后对身体的影响和有无传染性”处于不熟悉一端,这是引起民众风险意识的主要因素。（3）结构方程分析结果表明,SARS疫情信息是通过风险认知对个体的应对行为、心理健康产生影响的, 并初步验证了风险评估、心理紧张度、应对行为和心理健康等指标对于危机事件中民众心理行为的预测作用     

Attention, Self-Control, and Health Behaviors

ABSTRACT— Past research has shown that limitations on attention can lead to loss of control. Our model of self-control suggests that when attentional resources are restricted, individuals can focus on only the most salient behavioral cues, to the neglect of more distal stimuli. Subsequent action is then likely to be under the near-exclusive motivational influence of those "central" cues. This state of narrowed attentional focus, which we term "attentional myopia," is predicted to lead to loss of control when salient cues serve to promote a behavior that violates self-standards. By contrast, limitations on attention can lead to more successful self-control when salient cues instead suggest restraint. We have investigated this model in the health domains of eating, smoking, and aggression, and we discuss its implications for individuals' efforts to respond to health-relevant messages.     

健康焦虑的产生、分型及其治理

健康焦虑来源于健康的不确定性风险和风险感知。伴随风险社会中健康不确定性风险的日渐增多,公众对健康风险的感知越来越强,健康焦虑普遍存在于各类群体。基于健康焦虑产生的不确定性风险来源发现,健康焦虑可以分为由生活和劳动环境变化产生的环境型健康焦虑,由外部社会发展变化产生的结构型健康焦虑,突发事件导致的应激型健康焦虑,身体机能变化而来的生理型健康焦虑。以健康优先为原则推动个体和社会发展,降低环境健康风险,提升公众健康素养是缓解健康焦虑的应对之策。

     

Goal-striving and the implementation of goal intentions in the regulation of body weight

Abstract

The enactment of relatively easy-to-implement and relatively difficult-to-implement goal intentions was investigated in a field study of body weight maintenance for 141 university students. Three appraisal processes were examined as mechanisms for implementing intentions: self-efficacy, outcome expectancy, and affect towards means. The results showed that goal-directed dieting behaviours for men and women and goal-directed exercising/sport activities for men were influenced by the appraisals in a linear compensatory manner, and goal-directed exercising/sport activities for women were influenced by the appraisals via a three-way interaction. Self-efficacy, in particular, was a strong, pervasive determinant of both dieting and exercising/sport activities for men and women.     

Temperament as Risk and Protective Factors in Obesogenic Eating: Relations Among Parent Temperament,Child Temperament,and Child Food Preference and Eating

Children’s food preferences and eating behaviors have implications for their health and weight status, serving as risk or protective factors for obesity. Although parent and child factors influence children’s eating, few studies have examined parent and child temperament simultaneously in relation to child food preference and eating behaviors. The authors addressed this research gap. Participants were 115 ethnically diverse children between 4 and 6?years old and their parents. Measures included parental temperament traits, parental anxiety, child temperament traits, and child food preference and eating behaviors observed using a laboratory procedure. Results show that children preferred candies over grapes, and that aspects of both child and adult temperament were related to child eating behaviors. Child surgency was linked to eating more candies, while child effortful control was linked to eating more grapes. Parent effortful control was related to children’s preference toward grapes. No relations were found between child eating behaviors and child or parent negative affectivity and parental anxiety. Overall, findings suggest that highly impulsive and poorly self-regulated children may be at risk for obesogenic eating habits.     

抚养困难与教养行为的关系及其调节因素

本研究考察了567名2-5岁幼儿母亲的抚养困难与教养行为的关系,并进一步探讨了在高抚养困难情景下母亲教养行为的可能调节因素.结果发现(1)幼儿母亲的抚养困难感受总分与其教养行为的各个侧面均有非常显著的相关,母亲抚养困难程度越高,则其敏感性、参与性、积极情感及对儿童发展的指导性均较低,而其对儿童的消极情感较多;(2)回归分析表明,来自儿童侧面的"积极强化缺乏"、"多动/注意分散"、"不良心境"与"过度要求"以及来自母亲侧面的"缺乏依恋"、"缺乏能力感"等方面的抚养困难是预测母亲教养行为的重要因素;(3)在母亲抚养困难较高的情况下,夫妻双方的受教育水平分别对母亲教养行为的一些侧面具有调节作用.     

Optimism,goals, and threats: How to conceptualize self-regulatory processes in the adoption and maintenance of health behaviors

Abstract

How individuals control themselves and their health behaviors can be better understood by examining their self-beliefs in terms of threats and goals. The distinction between self-regulatory threat appraisals and self-regulatory goal attainment may help to explain when individuals fall prey to defensive optimism and when they are guided by functional optimism. To underscore the notion of process-specific self-beliefs, a further distinction is made between goal-setting self-efficacy, action self-efficacy, coping self-efficacy, and recovery self-efficacy.     

How optimists face skin cancer information: Risk assessment,attention, memory,and behavior

The purpose of the present study was to investigate how optimists process health-related information. Sixty-five young adults (ages 18–35) reported skin cancer-related knowledge and behaviors, and read slides of information on skin and skin cancer. Visual attention to the slides was recorded using eye tracking, and their memory for the information was measured. Additionally, participants’ self-reported skin cancer-relevant behavior was assessed prospectively in the months following the lab component of the study. Results show that individuals low in dispositional optimism or high in health-related optimism paid more attention when they were at high objective risk of developing skin cancer; and individuals high in dispositional optimism or high in health-related optimism were more likely to perform adaptive, health-promoting behaviors. In addition, optimistic beliefs were found not to be related with unrealistic optimism. Dispositional and health-related optimism therefore appear to predict health-related cognition and behavior in distinct ways.     

Reducing the Risk for Preschool Expulsion: Mental Health Consultation for Young Children with Challenging Behaviors

Increasing numbers of young children are being expelled from child care settings because of their problem behavior. Access to mental health consultation is related to lower rates of expulsion, but additional data are needed to document the pathways through which mental health consultation reduces the risk of expulsion. We report on outcomes from a 4-year project designed to reduce the number of children expelled for problem behavior in a large suburban county in Maryland. Two master’s-level professionals provided behavioral consultation to child care providers who identified nearly 200 children at imminent risk for expulsion. Child care providers rated children’s social skills and problem behaviors at referral and discharge using the Preschool Kindergarten Behavior Scales and the Brief Infant Toddler Social Emotional Assessment. Statistically significant increases in social skills and reductions in problem behaviors were seen for children who received individualized consultation. More than three-quarters of the children who were at risk for expulsion were able to be maintained in their current child care placement; of those that changed placements, only half (n = 13) were removed involuntarily. These findings provide additional support for mental health consultation as a promising strategy to reduce the risk for expulsion for young children with problem behaviors.     

健康行动过程取向模型的发展与前景

健康行动过程取向(HAPA)模型的提出源于健康行为社会认知模型的发展和Bandura社会认知理论的应用。在HAPA中, 健康行为变化被视为一个包括行为产生、保持和恢复在内的连续过程; 结果预期、危险感知、三种自我效能感和两类计划被用来解释意图的形成及其向行动的转化; 两个阶段的划分有助于区分三类干预对象, 建议实施菜单式干预。HAPA模型具有明显的理论优势, 也引发了有关模型实质的争论。当前和未来的研究旨在考察更多的自我调节变量、检验因果模型, 在健康行为的多个领域开展应用和干预研究。
