Verbal fluency and verbal comprehension abilities in synonym tasks

Generating different synonym candidates and evaluating these candidates with respect to their synonymy with the stimulus word are two components of solving an open synonym task, which requires giving synonyms for a given word (cf. Janssen, Hoskens, & De Boeck, 1993). Separate subtasks were designed to identify these components. It is shown in this study that the generation component ability is primarily related to verbal fluency abilities, whereas the evaluation component ability is primarily related to verbal comprehension abilities. Moreover, evidence is given that these two component abilities can account for the correlations of the open synonym task with other ability measures.     

The Impact of Social Influences in the Context of Attitude,Self-Efficacy,Intention, and Previous Behavior as Predictors of Smoking Onset1

Three different constructs for measuring social influence were utilized in the present study to explain adolescents' present and future smoking behavior at 6 (T2), 12 (T3), and 18 months (T4) after the first test. Social influence was assessed by measuring the social norms, perceived smoking behavior, and direct pressure. The impact of the social influence constructs was also assessed in the context of broader models, including attitudes and self-efficacy expectations, intention, and previous behavior. The three social influence measures correlated significantly with intention and behavior. Stepwise regression analyses showed that perceived behavior and pressure made significant contributions, after entering social norms, in explaining actual and future adolescent smoking behavior. Adding attitudes and self-efficacy increased the predictive power of the model significantly. In agreement with the theory of Fishbein & Ajzen (1975), intention was the most powerful predictor in explaining present and future smoking behavior. Attitudes, self-efficacy, and the social influences also made small unique contributions improving the explanatory power by approximately 5%. Previous behavior, however, had a substantial unique contribution in predicting future behavior after attitudes, social influences, self-efficacy, and intention were entered in the equations. Since social influences may exert their impact via different routes, it is recommended that smoking prevention programs discuss not only overt pressures such as direct pressure from peers, parents, and media, but also address the more covert social pressures such as modeling and the adolescents' ability to cope with these covert influences. Furthermore, norms on nonsmoking should be made explicit.     

A Review of Determinants of and Interventions for Proenvironmental Behaviors in Organizations

A review of empirical studies on proenvironmental behaviors in organizational contexts is presented. Twenty‐one studies met the inclusion criteria. Quantitative effect sizes were compared where statistics were available and research designs were comparable. Characteristics of the dependent variable and the targeted organizational (sub)populations were systematically examined. With respect to individual‐specific determinants, the results show relatively consistent effects for attitudinal determinants and past behavior. For organization‐specific influences, management and physical facilitation were frequently significant. Findings related to other factors are less conclusive. Given the available evidence and feasibility considerations, it is recommended that interventions focus on physical facilitation, tailored persuasive communication, and active engagement of middle management. It is further recommended that future research integrates the analysis of individual and organizational determinants.

Sixty years of fear appeal research: Current state of the evidence

Fear arousal is widely used in persuasive campaigns and behavioral change interventions. Yet, experimental evidence argues against the use of threatening health information. The authors reviewed the current state of empirical evidence on the effectiveness of fear appeals. Following a brief overview of the use of fear arousal in health education practice and the structure of effective fear appeals according to two main theoretical frameworks—protection motivation theory and the extended parallel process model—the findings of six meta‐analytic studies in the effectiveness of fear appeals are summarized. It is concluded that coping information aimed at increasing perceptions of response effectiveness and especially self‐efficacy is more important in promoting protective action than presenting threatening health information aimed at increasing risk perceptions and fear arousal. Alternative behavior change methods than fear appeals should be considered.     

Finding theory‐ and evidence‐based alternatives to fear appeals: Intervention Mapping

Fear arousal—vividly showing people the negative health consequences of life‐endangering behaviors—is popular as a method to raise awareness of risk behaviors and to change them into health‐promoting behaviors. However, most data suggest that, under conditions of low efficacy, the resulting reaction will be defensive. Instead of applying fear appeals, health promoters should identify effective alternatives to fear arousal by carefully developing theory‐ and evidence‐based programs. The Intervention Mapping (IM) protocol helps program planners to optimize chances for effectiveness. IM describes the intervention development process in six steps: (1) assessing the problem and community capacities, (2) specifying program objectives, (3) selecting theory‐based intervention methods and practical applications, (4) designing and organizing the program, (5) planning, adoption, and implementation, and (6) developing an evaluation plan. Authors who used IM indicated that it helped in bringing the development of interventions to a higher level.     

Differences in psychosocial factors and fat consumption between stages of change for fat reduction

Abstract

Differences in fat consumption and psychosocial factors between subjects in different trans-theoretical stages of change for fat reduction were studied. Data on fat consumption, self-rated fat intake, attitudes, social support and self-efficacy were collected among a sample of 507 adults. Analysis of variance with Scheffe's multiple-comparison test was used to study differences in these factors between stages of change. Attitudes and social support were most positive among subjects in preparation and action. Self-efficacy expectations were lowest among subjects in contemplation and preparation. Fat consumption was highest among precontemplators hut no substantial differences between other stages were found. It is concluded that subjects in different stages of change differ in psychosocial factors that are regarded as important determinants of behavioral change. Based on these differences it is recommended to develop stage-tailored nutrition education. A majority of subjects in maintenance consumed more fat than is recommended. Therefore, it is suggested that the usually applied staging algorithms might need adjustment for a valid application in nutrition research.     

Maternal and Paternal Perception of Child Vulnerability and Behaviour Problems in Very Preterm Born Children

Preterm born children have more behaviour problems than term born children. Perinatal risks, current child functioning, sociodemographic characteristics, parental psychological distress and parental perceptions of child vulnerability (PCV) have been shown to be risk factors for behaviour problems. However, the role of maternal and paternal PCV is unclear, as these have not been investigated as a risk factor for behaviour problems, with all other risk factors taken into account. Aim of this study is to investigate whether maternal and paternal PCV are independent risk factors for behaviour problems in very preterm (VP) and term born children. The present study is a single centre prospective cohort study. Preterm children (n = 104), born at <30 weeks' gestation and/or birth weight <1000 g, and term children (n = 95) were assessed at age 5. Results showed that risk factors for parent‐rated behaviour problems were low/middle parental education, VP birth, parental stress and, in VP children, maternal PCV. Risk factors for teacher‐rated behaviour problems were low/middle parental education, foreign parental country of birth, intrauterine growth restriction and objective child vulnerabilities. It can be concluded that maternal PCV is a risk factor for parent‐rated behaviour problems in VP children. When VP children are presented with behavioural problems, clinicians ought to be aware of the possibility that parents might still perceive their child as vulnerable. The neonatal history of the child, the way parents experienced that period, their perceptions of the child and possible consequences of these perceptions could be subjects for conversation during visits at follow‐up clinics.
