Distracted pedestrians in crosswalks: An application of the Theory of Planned Behavior

Thousands of adult pedestrians are killed or injured each year. In spite of ever growing knowledge of correlates of risk pedestrian behavior, much remains to be learned. A small body of research has applied the Theory of Planned Behavior (TPB) to the problem of risky crossing decisions. We employed TPB to examination of intentions to cross under varying types of distraction. Eighty adults completed measures of injury exposure, followed by a questionnaire structured around TPB assessing intentions to cross streets under common conditions of self-imposed distraction. Results were similar to other research, suggesting attitude and perceived behavioral control predicted intentions to cross streets while distracted. Results are discussed in the context of similar studies, and with regard to future directions and injury prevention efforts.     

Test–retest reliability of the Brunel Lifestyle Physical Activity Questionnaire

ObjectivesTo establish the test–retest reliability of planned physical activity (PPA) and unplanned physical activity (UPA) components of the Brunel Lifestyle Physical Activity Questionnaire (BLPAQ). To provide evidence of the BLPAQ's stability using the proportion of agreement (PoA) method over a 5-week period.DesignTest–retest over a 5-week period using three diverse samples of adults.MethodsThe 277 participants were subdivided into three adult samples: gymnasium users (n = 80), undergraduate students (n = 111), and university staff members (n = 86). They were asked to complete the test–retest measure in their places of exercise, study, or work respectively.ResultsCorrelation coefficients between test–retest administrations were calculated for each participant group and intraclass correlations were calculated for each item. Pearson's product-moment correlations ranged from r = 0.95 to r = 0.96 for the PPA subscale and r = 0.93 to r = 0.98 for the UPA subscale. Intraclass correlations ranged from R = 0.52 to R = 0.99 for PPA and R = 0.87 to R = 0.99 for UPA. Fisher's z tests indicated that the test–retest correlation coefficients for the BLPAQ subscales were, on the whole, significantly stronger than those of older, comparable subscales from lifestyle physical activity questionnaires. The PoA analysis for each item revealed that the test–retest administrations were in high agreement (>95%).ConclusionsOverall, the PPA and UPA factors of the BLPAQ demonstrated high reliability and stability. The present study also illustrates the utility of PoA analysis in establishing the stability of physical activity measures.     

Dual imputation model for incomplete longitudinal data

Missing values are a practical issue in the analysis of longitudinal data. Multiple imputation (MI) is a well‐known likelihood‐based method that has optimal properties in terms of efficiency and consistency if the imputation model is correctly specified. Doubly robust (DR) weighing‐based methods protect against misspecification bias if one of the models, but not necessarily both, for the data or the mechanism leading to missing data is correct. We propose a new imputation method that captures the simplicity of MI and protection from the DR method. This method integrates MI and DR to protect against misspecification of the imputation model under a missing at random assumption. Our method avoids analytical complications of missing data particularly in multivariate settings, and is easy to implement in standard statistical packages. Moreover, the proposed method works very well with an intermittent pattern of missingness when other DR methods can not be used. Simulation experiments show that the proposed approach achieves improved performance when one of the models is correct. The method is applied to data from the fireworks disaster study, a randomized clinical trial comparing therapies in disaster‐exposed children. We conclude that the new method increases the robustness of imputations.     

Accounting for the Theory of Planned Behaviour in departure time choice

Motivating people to change their departure time could play a key role in reducing peak-hour congestion, which remains one of the most prevalent transport problems in large urban areas. To achieve this behavioural change, it is necessary to better understand the factors that influence departure time choice. So far departure time choice modelling focussed mainly on objective factors, such as time and costs as main behavioural determinants. In this study, we derived psychological factors based on the Theory of Planned Behaviour, estimated them based on structural equation modelling, and included them into a discrete choice model. The psychological factors were measured based on an online questionnaire addressed to car commuters to the city centre of Copenhagen (N = 286). The questionnaire additionally included a travel diary and a stated preference experiment with nine departure time choice scenarios. All psychological factors had a significant effect on departure time choice and could improve the model as compared to a basic discrete choice model without latent constructs. As expected, the effects of the psychological factors were different depending on framework conditions: for people with fixed starting times at work, the intention to arrive at work on time (as estimated by subjective norm, attitude, perceived behavioural control) had the strongest effect; for people with flexible working hours, the attitude towards short travel time was most relevant. Limitations, the inclusion of additional psychological factors and their possible interactions are discussed.     

Intention to Participate in Predictive Genetic Testing for Hereditary Cancer: The Role of Attitude toward Uncertainty

This study aimed to identify factors predictive of intentions to participate in genetic testing for hereditary cancer. Measures of the psychosocial influences on intention were based on the theories of reasoned action (TRA) and planned behaviour (TPB) and a new measure of Attitude toward Uncertainty. The participants (the breast cancer sample, n = 124; the colon cancer sample, n = 168) were recruited via a general practitioner's patient database and asked to complete postal questionnaires. The overall response rate was 57.4% (54.7% in the colon cancer sample, 61.4% in the breast cancer sample). In the colon cancer sample, 72% of respondents stated that they would choose to participate in genetic testing for colon cancer susceptibility. In the breast cancer sample, 77% of respondents stated that they would choose to participate in genetic testing for breast cancer susceptibility. The TRA components (attitudes and subjective norms) and Attitude toward Uncertainty emerged as the strongest predictors of intention. The Attitude toward Uncertainty appears to moderate intention in that participants with more negative attitudes toward uncertainty are more likely to undergo the test than those seeking more certainty.     

Prospective Study on the Determinants of Repeat Attendance and Attendance Patterns in Breast Cancer Screening Using the Theory of Planned Behaviour

This prospective study, using the Theory of Planned Behaviour (TPB) as a theoretical framework, was carried out to identify the determinants of repeat attendance and attendance patterns in organised breast screening. A group of 2657 women filled out a baseline questionnaire, approximately 8 weeks after having been invited for an initial screening in the Dutch Breast Cancer Screening Programme. Data on actual attendance in second and third screening round were subsequently collected. Personal variables such as family history of breast cancer, breast cancer in someone close and fear of breast cancer were not related to repeat attendance. The TPB variables could explain approximately 17% of the variance in attendance in the second and third round. Maintenance behaviour (consistent attendance vs. dropout) was related to the TPB variables, but the amount of variance explained was only 6%. Initiation of behaviour (consistent refusal vs. delayed attendance) also was related to TPB variables, with a substantially higher amount of explained variance than with maintenance behaviour. Results indicate that the TPB variables are more related to the initiation of screening behaviour than to the maintenance of screening behaviour. Implications of these findings for breast cancer screening are discussed.     

Intergenerational occupational transmission: Do offspring walk in the footsteps of mom or dad,or both?

The purpose of this research was to apply the Theory of Planned Behavior (TPB) in order to investigate intergenerational occupational transmission between parents and their children. A sample of 260 undergraduate students completed a questionnaire measuring TPB variables, and congruence was calculated between the parents' occupations and their offspring's chosen profession. Intention to work in the parents' occupations was predicted by attitude, subjective norm and perceived behavioral control. Congruence between parents' and their children's occupational choice was predicted by intention and perceived behavioral control. The findings provide support to the relational approach in career choice. Implications of the findings for career counselors and young people's career choices are discussed.     

集体主义与贿赂

贿赂是指财物由行贿者向受贿者转移, 公共权力由受贿者向行贿者的暂时转移, 并涉及到为私利而滥用公共权力的过程。研究者认为集体主义是影响贿赂的文化心理根源, 而实证研究发现集体主义与贿赂的关系受到两个方面因素的影响。一方面贿赂的研究视角影响集体主义与贿赂的关系。研究一致证明集体主义促进贿赂行为意向。然而虽然大部分研究表明集体主义与贿赂感知和贿赂态度正相关, 但仍有少量不一致结果。另一方面集体主义类型也影响着集体主义和贿赂的关系。前人关于集体主义对贿赂的作用机制仍以理论探讨为主, 实证研究主要以道德卷入和计划行为理论为基础。未来可以从澄清不同贿赂研究视角的区别与联系、区分不同类型集体主义与贿赂的关系以及关注集体主义对贿赂的作用机制这三个角度进行深入探索。     

Socioeconomic status as a moderator between social cognitions and physical activity: Systematic review and meta-analysis based on the Theory of Planned Behavior

BackgroundHealth inequalities are to a substantial degree due to socioeconomic status (SES) related differences in health behaviors such as physical activity. However, little is known about the role SES plays in the self-regulation of physical activity.PurposeThis systematic review with meta-analysis examines whether a comprehensive set of indicators of SES (income, education, occupational status) impacts on the behavioral self-regulation by moderating the relationships between social cognitions in the Theory of Planned Behavior (TPB) and physical activity.MethodsA systematic literature search identified 99 studies from 88 articles that provided information on sample SES and correlations between TPB variables and physical activity. Random-effects meta-analyses were used to pool correlations corrected for sampling and measurement error. Random-effects meta-regression was used to examine moderating effects of study-level SES on these correlations.ResultsEducation moderated the relationship between intentions and physical activity, such that studies with better educated samples reported stronger intention-physical activity relationships.ConclusionsThese results suggest that education might play a major role in the self-regulation of physical activity, with better educated samples more likely to translate intentions into behavior. This can both help to explain heterogeneity in the relation between intentions and physical activity as well as support the development of more effective interventions targeting intentions and physical activity.     

品牌社区的形成与发展:社会认同和计划行为理论的视角

品牌社区是指一种特定的,不受地域限制的,基于某一品牌崇拜者之间结构化的社会关系而建立的社区。大量研究围绕社会认同理论、计划行为理论等相关理论,试图揭示品牌社区的形成、发展及作用机制。现有研究发现消费者对品牌的态度及其所感受到的主观行为规范等因素会影响个体的社区参与水平,而参与品牌社区有助于社区成员产生品牌认同,进而有效地维持并提高其品牌忠诚度。未来研究应该更多地关注自尊、自我意识以及社会认同威胁等变量。此外,国内研究者还应当考虑到东西方文化差异,促进相关理论及概念的本土化。
