系列再生法:实验模拟文化动态(英文)

系列再生法是一种用来探讨文化动态中的社会心理过程之实验方法。所谓文化动态是指文化如何形成、维持,以及如何随着时间而变化。此方法特别有利于以下研究:文化讯息是如何透过社会网络被传播、什么类型的文化讯息较可能透过社会网络被传播,以及文化讯息由一个人传到另一个人的过程中,是如何转化的。本文概述了系列再生实验方法的优点及缺点,讨论此方法的理论架构,并举例展诉如何有系统地应用此法,做有关文化刻板印象的研究。最后,本文讨论未来的研究方向,如文化动态的潜在文化差异,以及文化动态与社会网络之间的互动过程。     

An Investigation of the Sample Performance of Two Nonnormality Corrections for RMSEA

The root mean square error of approximation (RMSEA) is a popular fit index in structural equation modeling (SEM). Typically, RMSEA is computed using the normal theory maximum likelihood (ML) fit function. Under nonnormality, the uncorrected sample estimate of the ML RMSEA tends to be inflated. Two robust corrections to the sample ML RMSEA have been proposed, but the theoretical and empirical differences between the 2 have not been explored. In this article, we investigate the behavior of these 2 corrections. We show that the virtually unknown correction due to Li and Bentler (2006) Li, L. and Bentler, P. M. 2006. “Robust statistical tests for evaluating the hypothesis of close fit of misspecified mean and covariance structural models.”. In UCLA Statistics Preprint #506. Los Angeles: University of California..  [Google Scholar], which we label the sample-corrected robust RMSEA, is a consistent estimate of the population ML RMSEA yet drastically reduces bias due to nonnormality in small samples. On the other hand, the popular correction implemented in several SEM programs, which we label the population-corrected robust RMSEA, has poor properties because it estimates a quantity that decreases with increasing nonnormality. We recommend the use of the sample-corrected RMSEA with nonnormal data and its wide implementation.     

A qualitative exploration of the health promotion effects of varying body size in photographs analyzed using Interpretative Phenomenological Analysis

As levels of obesity continue to rise worldwide so do the number of public health campaigns designed to help address this problem with advice and information on how to stabilize or decrease weight. However, few studies have explored the influence of visual images, and specifically photographs, in weight-related health materials despite their widespread use in publications and online. We carried out qualitative individual telephone interviews with eight women who were actively engaged in managing their weight. They viewed a series of photographs of slim and overweight women demonstrating healthy behaviors such as engaging in physical activity or reading a food label. Responses were analyzed using Interpretative Phenomenological Analysis. The two core themes that emerged were the motivating/de-motivating effect of body size representation on health behavior intentions, and the social implications of being overweight. Participants liked and appeared motivated by the images of larger women, actively seeking out social comparisons. Implications of these findings in the development of health promotion messages are discussed.     

Predictors of Diabetes Self‐care,Metabolic Control,and Mental Health in Youth with Type 1 Diabetes

The purpose of this study was to explore the psychosocial predictors of diabetes self‐care (adherence to care regimes), metabolic control (glycated haemoglobin), and mental health among rural‐ and urban‐dwelling youth with type 1 diabetes. One hundred and twenty three adolescents/young adults (aged 13?25 years, mean = 16 years, standard deviation = 3.8 years) with type 1 diabetes, 50 males and 73 females, completed questionnaires reporting on diabetes self‐care, metabolic control, mental health (negative affect, quality of life), risk‐taking behaviours and attitudes, diabetes self‐efficacy, community engagement, and perceived social support. No rural/urban differences were detected on key predictors or outcome variables. Structural equation modelling revealed that high diabetes self‐efficacy, lower risk behaviour, and more conservative attitudes to risk taking predicted better diabetes self‐care, which in turn predicted better metabolic control and mental health. Social support and engagement in community activities did not influence diabetes self‐care. The study has significance because both diabetes self‐efficacy and propensity towards risk behaviour are potential targets for educational and counselling interventions designed to improve diabetes self‐care regimes and resultant metabolic and mental health outcomes.     

Exploring the Spiritual/Religious Dimension of Patients: A Timely Opportunity for Personal and Professional Reflection for Graduating Medical Students

Teaching about spirituality in medical school training is lacking. Spirituality is a dimension of humanity that can put experiences of health and illness into a meaningful context. Medical students might benefit from understanding how spirituality is an important element in learning to care for patients. Spirituality also provides a context for medical students to explore their own motivations for doctoring. This article describes a longitudinal senior elective course at the end of their medical school training to delve into matters of religion/spirituality surrounding patient care. The authors pose their own perspectives on what both students and faculty gained from the experience.     

Self-Construction,Cognitive Conflicts,and Disordered Eating Attitudes in Young Women

The aim of this study is to identify cognitive variables that predict disordered eating attitudes in a nonclinical sample composed of 50 female university students. Repertory grid technique was used to assess cognitive features of self-construing and cognitive conflicts. Drive for Thinness and Body Dissatisfaction scales from the Eating Disorder Inventory–2 were used as dependent variables, as previous studies suggested that high scores on these scales are associated with the risk of developing or aggravating eating syndromes. Results suggest that drive for thinness can be associated with cognitive conflicts, whereas body dissatisfaction may be higher for those who construct themselves as inadequate and similar to others. In addition, both dependent variables were predicted by being younger and having a higher body mass index.
