The current study examined whether an individualized motivational general-mastery MG-M imagery intervention consisting of daily imagery practice and weekly one-on-one guided imagery sessions could enhance self-efficacy in youth squash athletes (N = 5; M age = 10.80; SD = 1.93). A single-subject multiple-baseline design was employed spanning 13–18 weeks. Measures included the Sport Imagery Questionnaire for Children (Hall, Munroe-Chandler, Fishburne, & Hall et al., 2009) and a squash-specific self-efficacy questionnaire. Results indicated improvements in self-efficacy for 3 of the 5 athletes. The results from this study help inform researchers and practitioners regarding the use of MG-M imagery as a means to improve young athletes’ self-efficacy.  相似文献

We use longitudinal multilevel modeling to test how exposure to community violence and cognitive and behavioral factors contribute to the development of aggressive and prosocial behaviors. Specifically, we examine predictors of self-, peer-, and teacher-reported aggressive and prosocial behavior among 266 urban, African American early adolescents. We examine lagged, within-person, between-person, and protective effects across 2 years. In general, results suggest that higher levels of violence exposure and aggressive beliefs are associated with more aggressive and less prosocial peer-reported behavior, whereas greater self-efficacy to resolve conflict peacefully is associated with less aggression across reporters and more teacher-reported prosocial behavior. Greater knowledge and violence prevention skills are associated with fewer aggressive and more prosocial teacher-reported behaviors. Results also suggest that greater self-efficacy and lower impulsivity have protective effects for youth reporting higher levels of exposure to community violence, in terms of teacher-reported aggressive behavior and peer-reported prosocial behavior. Differences among reporters and models are discussed, as well as implications for intervention.  相似文献

Using multisource data, this article examined the relationship of two types of employee perceptions of overall fairness (i.e., fairness of the organization and fairness of the department), with supervisor ratings of in-role task performance and organizational citizenship behaviors (OCB). We also examined whether high-quality leader-member exchange (LMX) relationships compensate for negative effects of fairness on job performance and citizenship behaviors. Focusing on a sample of 154 health care workers, we found that only employee perceptions of overall fairness regarding the department were related to supervisory ratings of OCB and in-role task performance. Moreover, LMX moderated the relationships between fairness perceptions and (a) task performance, (b) organization-focused OCB, but not (c) individual-focused OCB. We discuss implications for research and the potential for reducing negative effects of low fairness perceptions on job performance through positive LMX.  相似文献

Distress tolerance (i.e., perceived or actual capacity to tolerate aversive internal states) has received considerable research attention as a transdiagnostic risk-factor underlying the development and maintenance of psychopathology. Lower levels of emotional distress tolerance have been linked to psychopathology (e.g. Posttraumatic Stress Disorder) within Military populations; however, the association of physical distress tolerance to psychopathology in this population has been under-researched. This research gap may be due in part to a paucity of comprehensive, temporally stable and brief measures of distress tolerance that have been validated within Military populations, which may hinder further examination and refinement of the construct. Addressing this problem, the current study evaluates the psychometric properties of a novel and brief measure of emotional and physical distress tolerance in a sample of United States post-9/11 Veterans. Participants were 307 Veterans (Mage = 38.9, 67.7% male) who completed the 10-item Distress Tolerance Inventory at baseline and annual follow-up. Exploratory structural equation modeling was used to examine the optimal latent factor structure and longitudinal invariance of the DTI measurement model, along with correlational analyses to examine the convergent properties of the DTI subscales. The DTI reflected a longitudinally invariant two-factor structure (emotional and physical distress tolerance), with excellent internal consistency and preliminary evidence of convergent validity. Thus, the DTI represents a brief, reliable and temporally stable measure of physical and emotional distress tolerance.  相似文献

In two experiments, 2.5‐year‐old children spontaneously used geometric information from 2D maps to locate objects in a 3D surface layout, without instruction or feedback. Children related maps to their corresponding layouts even though the maps differed from the layouts in size, mobility, orientation, dimensionality, and perspective, and even when they did not depict the target objects directly. Early in development, therefore, children are capable of noting the referential function of strikingly abstract visual representations.  相似文献

Social support is important in managing HIV and AIDS. Some people living with HIV or AIDS (PLWHA) have sought support from churches, despite their reputation for stigmatising PLWHA. Semi-structured interviews were conducted with 21 PLWHA and 21 church leaders to identify ways that churches can effectively enact support for PLWHA through improved communication about HIV, AIDS, and related issues. Church leaders also were asked about the institutional barriers to enacting support for PLWHA. Implementing these strategies consistently and holistically will require intentional efforts to address the barriers within church organisations to create environments that are welcoming to and supportive of PLWHA.  相似文献

Abstract

Conventional growth models assume that the random effects describing individual trajectories are conditionally normal. In practice, this assumption may often be unrealistic. As an alternative, Nagin (2005) Nagin, D. 2005. Group-based modeling of development, Cambridge: Harvard University Press. [Crossref] [Google Scholar] suggested a semiparametric group-based approach (SPGA) which approximates an unknown, continuous distribution of individual trajectories with a mixture of group trajectories.

Prior simulations (Brame, Nagin, &; Wasserman, 2006 Brame, R., Nagin, D. and Wasserman, L. 2006. Exploring some analytical characteristics of finite mixture models.. Journal of Quantitative Criminology, 22: 3159. [Crossref], [Web of Science ®] [Google Scholar]; Nagin, 2005 Nagin, D. 2005. Group-based modeling of development, Cambridge: Harvard University Press. [Crossref] [Google Scholar]) indicated that SPGA could generate nearly-unbiased estimates of means and variances of a nonnormal distribution of individual trajectories, as functions of group-trajectory estimates. However, these studies used few random effects—usually only a random intercept. Based on the analytical relationship between SPGA and adaptive quadrature, we hypothesized that SPGA's ability to approximate (a) random effect variances/covariances and (b) effects of time-invariant predictors of growth should deteriorate as the dimensionality of the random effects distribution increases. We expected this problem to be mitigated by correlations among the random effects (highly correlated random effects functioning as fewer dimensions) and sample size (larger N supporting more groups).

We tested these hypotheses via simulation, varying the number of random effects (1, 2, or 3), correlation among the random effects (0 or .6), and N (250, 500). Results indicated that, as the number of random effects increased, SPGA approximations remained acceptable for fixed effects, but became increasingly negatively biased for random effect variances. Whereas correlated random effects and larger N reduced this underestimation, correlated random effects sometimes distorted recovery of predictor effects. To illustrate this underestimation, Figure 1 depicts SPGA's approximation of the intercept variance from a three correlated random effect generating model (N < eqid1 > 500). These results suggest SPGA approximations are inadequate for the nonnormal, high-dimensional distributions of individual trajectories often seen in practice.

The following is a sermon preached by Nathan Carlin at St. John’s Church (United Church of Christ) in Houston, Texas, on January 27, 2013. In line with the conference theme—body/soul, spirit/flesh, self/other—the sermon focuses on several verses in Paul’s first letter to the church in Corinth in which Paul discusses the Church as the Body of Christ. The sermon text (1 Cor. 12:12–27) was not chosen because the author was still thinking about the conference theme (the conference, as noted, took place on October 17–19, 2012); this text simply happened to be the lectionary passage assigned to the date. In the sermon, the biblical text, the psychological concept of “the narcissism of minor differences,” and a story from the author’s childhood (a story about Bible quiz competitions) are interwoven. The author felt that such a topic was appropriate for St. John’s Church because the church, on the day that the sermon was delivered, was scheduled to meet about the topic of confirmation classes for youth. All of this is to say that sermons are often expressions of pastoral theology because sermons, while inherently theological, are also pastoral in that they are addressed to specific audiences and focus on matters that the preacher discerns to be of existential concern, both collectively and individually, for those whom the preacher is addressing. In terms of method and style, this sermon was written following the technique of Robert Dykstra as articulated in his Discovering a Sermon: Personal Pastoral Preaching.  相似文献
