Mindfulness training for loneliness among Chinese college students: A pilot randomized controlled trial

Loneliness has been found to predict a wide range of physical and mental health problems. It is suggested that China's One‐Child Policy places young Chinese people at a particularly high risk for loneliness. Although loneliness is most prevalent in late adolescence and early adulthood, interventions have primarily targeted children or older adults with limited success. The current study examines a pilot randomized controlled trial of a mindfulness training program among Chinese college students. Participants with elevated loneliness (N = 50, ages 17–25) were randomized into either an 8‐week mindfulness training or a control group. Self‐reported measures of loneliness and mindfulness were administered at baseline and posttest. The training group also completed a program evaluation form and a 3‐month follow‐up assessment. Results provided preliminary evidence indicating that the intervention was feasible and effective at reducing loneliness among Chinese college students. Limitations and future directions were discussed. 相似文献

Process factor analysis (PFA) is a latent variable model for intensive longitudinal data. It combines P-technique factor analysis and time series analysis. The goodness-of-fit test in PFA is currently unavailable. In the paper, we propose a parametric bootstrap method for assessing model fit in PFA. We illustrate the test with an empirical data set in which 22 participants rated their effects everyday over a period of 90 days. We also explore Type I error and power of the parametric bootstrap test with simulated data. 相似文献

Considering self‐interests and symbolism together: How instrumental and value‐expressive motives interact to influence supervisors’ justice behavior

Drawing upon functional theories of attitudes and the organizational justice literature, the current research suggests that people's attitudes toward justice likely serve an instrumental function (grounded in self‐interest, rewards maximization, and punishment minimization) as well as a value‐expressive function (grounded in the expression of self‐concept and values). Importantly, these two functions co‐exist and interact to influence supervisors’ justice behavior and the consistency of such behavior via supervisors’ justification for unjust behavior. Findings from a set of experimental and correlational studies confirmed these predictions. The positive effects of supervisors’ value‐expressive function on justice behavior and its consistency were stronger when their instrumental function was lower (vs. higher), and justification for unjust behavior mediated these effects. Also, supplementary analyses showed that the consistency of supervisors’ justice behavior positively predicted subordinates’ overall justice perceptions beyond the effects of the overall level of justice behavior. We conclude by discussing the theoretical and practical implications of these findings. 相似文献

The relationship between risk-taking and creativity is critical to understanding social harmony and innovation. Although some studies have assessed the link between risk-taking and divergent thinking, the association between risk-taking and convergent thinking remains unclear. Two studies were conducted to systemically investigate whether risk-taking is linked to convergent thinking. In Study 1, a sample of 127 healthy participants performed a Chinese remote associate test (RAT) and completed a risk-taking questionnaire. As predicted, risk-taking was negatively correlated with RAT performance, implying that risk-taking has a negative association with convergent thinking. Study 2 was an online survey study that replicated Study 1 and extended the measures to include self-rated risk and a measure of divergent thinking (the alternate uses task). The findings were fully replicated, showing that low risk-taking goes with better convergent thinking and risk-taking was not significantly correlated with divergent thinking. Furthermore, the risk-taking/convergent-thinking relationship was best described by a linear regression model in both studies. Taken together, these results suggest that appropriate reductions in risk-taking can boost convergent thinking. 相似文献

Observers perceive objects in the world as stable over space and time, even though the visual experience of those objects is often discontinuous and distorted due to masking, occlusion, camouflage, or noise. How are we able to easily and quickly achieve stable perception in spite of this constantly changing visual input? It was previously shown that observers experience serial dependence in the perception of features and objects, an effect that extends up to 15 seconds back in time. Here, we asked whether the visual system utilizes an object’s prior physical location to inform future position assignments in order to maximize location stability of an object over time. To test this, we presented subjects with small targets at random angular locations relative to central fixation in the peripheral visual field. Subjects reported the perceived location of the target on each trial by adjusting a cursor’s position to match its location. Subjects made consistent errors when reporting the perceived position of the target on the current trial, mislocalizing it toward the position of the target in the preceding two trials (Experiment 1). This pull in position perception occurred even when a response was not required on the previous trial (Experiment 2). In addition, we show that serial dependence in perceived position occurs immediately after stimulus presentation, and it is a fast stabilization mechanism that does not require a delay (Experiment 3). This indicates that serial dependence occurs for position representations and facilitates the stable perception of objects in space. Taken together with previous work, our results show that serial dependence occurs at many stages of visual processing, from initial position assignment to object categorization. 相似文献
