Children's perceptions and experiences of care giving: A focus group study

The stress of care giving for spouses and adult children has been extensively documented in the empirical literature. More recently attention has been paid to children's involvement in family care giving. Qualitative studies in the social welfare field have highlighted the social restrictions caring places upon children. There remains a need, however, to understand what children are thinking and feeling in an effort to cope with their care-giving demands. This study used a focus group methodology and individual interviews to explore the experiences of 17 young carers aged between 10 and 16. Thematic analysis was employed to identify themes relating to the nature of stressors, their appraisal of them, and the coping strategies they use to manage the task of caring.     

Regulatory Focus Strategies Scale: A measure of individual differences in the endorsement of regulatory strategies

Regulatory focus theory proposes that people can have a promotion or a prevention focus when pursuing goals and choosing strategies. The Regulatory Focus Strategies Scale (RFSS), a scale that assesses the endorsement of promotion and prevention strategies for goal pursuit, is developed and validated in three studies. Exploratory and confirmatory factor analyses in Australia and Japan showed that promotion- and prevention-focused strategic endorsement formed two largely uncorrelated factors. The RFSS exhibits adequate reliability, and discriminant and convergent validity. A cross-cultural comparison showed that Australians were more promotion- but less prevention-focused than Japanese students. The RFSS provides an additional measure that is useful in future research on self-regulatory strategies.

通过问卷调查与结构方程建模分析组织信任对于员工工作绩效的影响途径。203名被试和他们的上司参与了问卷调查。结果分析采用潜变量路径分析方法。我们构建多组模型与构思模型,通过两个阶段的检验,分析了组织信任的作用机制。结果表明：组织信任作用于心理安全感,而心理安全感通过两条独立途径影响工作绩效,分别是工作聚焦与工作改进。心理安全感能够促进员工针对工作的不断改进的行为和探索新工作方法的意愿,同时也有利于员工集中精力在工作上,从而提高个人工作业绩     

Regulatory focus as a predictor of omission bias in moral judgment: Mediating role of anticipated regrets

Omission bias occurs when people are more reluctant to accept negative consequences caused by their actions than by their inaction. Recent research on omission bias in decision‐making has found evidence for individual differences, thus indicating that some people are more likely to show omission inclination than others. The present research aims to explore the role of regulatory focus as individual difference variables in omission bias. Moreover, we examine whether anticipated regret mediates the relationship between regulatory focus and moral judgement. Moral judgement tasks utilized include: (i) moral dilemma scenarios (Study 1); and (ii) ethical scenarios embracing apparent legal rule violations (Study 2). The results of both studies show that only prevention focus is significantly related to omission bias in moral judgement. Specifically, this relationship holds regardless of the nature of the ‘omission’ (whether they are deontological or utilitarian). In addition, anticipated regret/guilt for action was found to mediate the relationship between prevention focus and omission bias. Implications and limitations are discussed based on the results of the current study.     

The influence of attentional focus on the development of skill representation in a complex action

ObjectivesRecent research has indicated that performers' mental representation of a motor skill changes over the course of learning. In the present study, we sought to ascertain whether the type of instructions (instructions that emphasize either an internal or external focus of attention) influences the development of skill representation during motor learning.DesignParticipants without golf experience were recruited to practice a golf putting task over the course of three training days. Participants were randomly assigned to either an internal focus (focus on the swing of the arms; n = 10) or external focus (focus on the speed of the ball roll; n = 10) learning group. Changes in putting performance and mental representation structure were assessed over the course of learning, as well as during a follow-up retention test two days after practice.MethodsMental representation structure was measured employing the structural dimensional analysis of mental representations (SDA-M), which provided psychometric data on the structure of the mental representation in long-term memory. Additionally, the change in putting accuracy and consistency was recorded over the course of learning.ResultsFindings indicated that the external focus group performed with greater accuracy and consistency during training, and revealed a larger degree of development in their mental representation of the putting task.ConclusionsOverall, our findings suggest that facilitating the link between an action and its effect by means of an external focus is crucial for motor performance as well as the development of skill representation.     

The network of conscientiousness

According to the network perspective, the coalescence of several personality characteristics into major personality dimensions results from a pattern of complex interactions that can be modeled as a network. We focused on one personality dimension, conscientiousness, and on its main facets. We administered a large battery of questionnaires to two samples (N = 210 and N = 230) and analyzed them by means of network analysis. The results showed that some elements of the network, such as general self-control and orientation toward the future, characterized all facets. These “shared” elements could be responsible for the facets to clump into one major dimension. Other elements of the network uniquely characterized different facets. These “unique” elements could underlie the main differences among conscientiousness facets.     

Enhanced retention of drop vertical jump landing technique: A randomized controlled trial

External focus instructions have been shown to result in superior motor performance compared to internal focus instructions. Using an EF may help to optimize current anterior cruciate ligament (ACL) injury prevention programs. The purpose of the current study was to investigate the effects of instructions on landing technique and performance by comparing an external focus (EF), internal focus (IF), video (VI) and control (CTRL) group. Subjects (age 22.50 ± 1.62 years, height 179.70 ± 10.43 cm, mass 73.98 ± 12.68 kg) were randomly assigned to IF (n = 10), EF (n = 10), VI (n = 10) or CTRL group (n = 10). Landing was assessed from a drop vertical jump (DVJ) in five sessions: pretest, two training blocks (TR1 and TR2) and directly after the training sessions (post test) and retention test 1 week later. Group specific instructions were offered in TR1 and TR2. Landing technique was assessed with the Landing Error Scoring System (LESS) and jump height was taken as performance measure. The results show that males in the VI group and females both in the VI and EF groups significantly improved jump-landing technique. Retention was achieved and jump height was maintained for males in the VI group and females both in the VI and EF groups. It is therefore concluded that EF and VI instructions have great potential in ACL injury prevention.     

Regulatory focus and adherence to self-care behaviors among adults with type 2 diabetes

The aims of this study were, first, to test the association between regulatory focus of adults with type 2 diabetes and their adherence to two types of self-care behaviors – lifestyle change (e.g. physical activity and diet) and medical care regimens (blood-glucose monitoring, foot care and medication usage). Second, to explore whether a fit between the message framing and patients’ regulatory focus would improve their intentions to adhere specifically when the type of behavior fits the patients’ regulatory focus as well. A cross-sectional study was conducted among 130 adults with type 2 diabetes who were hospitalized in an academic medical center. The patients completed a set of questionnaires that included their diabetes self-care activities, regulatory focus, self-esteem and demographic, socioeconomic and clinical data. In addition, participants were exposed to either a gain-framed or a loss-framed message, and were then asked to indicate their intention to improve adherence to self-care behaviors. A multivariable linear regression model revealed that promoters reported higher adherence to lifestyle change behaviors than preventers did (B = .60, p = .028). However, no effect of regulatory focus on adherence to medical care regimens was found (B = .46, p = .114). In addition, preventers reported higher intentions to adhere to medical care behaviors when the message framing was congruent with prevention focus (B = 1.16, p = .023). However, promoters did not report higher intentions to adhere to lifestyle behaviors when the message framing was congruent with promotion focus (B = ?.16, p = .765). These findings justify the need to develop tailor-made interventions that are adjusted to both patients’ regulatory focus and type of health behavior.     

How religiosity shapes health perceptions and behaviors of Latina immigrants: is it an enabling or prohibitive factor?

The study examines how religiosity shapes the health perceptions and health-related behaviors of 50 Latina immigrants from El Salvador, Guatemala, Mexico and Bolivia. Between May and August 2011, focus groups were conducted with participants representing each country of origin. Qualitative content analysis was the analytic strategy adopted in the study. The meta-theme, Religiosity Contributes to Positive Perceptions of Health and Health-Promoting Behaviors, is associated with six emerging themes: (1) Religiosity promotes a sense of personal responsibility for one’s health; (2) Religiosity promotes a holistic view of health; (3) Religiosity promotes the view that health is a priority; (4) Religiosity promotes the view that health enables one to perform necessary tasks; (5) Religiosity promotes health-seeking behavior; and (6) Religiosity provides intrinsic health benefits. Findings do not follow the clear-cut dichotomy of the health locus of control model and challenge simplified notions that Latinas hold a purely external health locus of control toward their health and health care. Latinas rely on both God and themselves in managing their health and engaging in health-promoting actions, which are prompted in large part by their religiosity. Implications for culturally appropriate health communication and interventions are discussed.
