摘要：
Anhedonia, the experience of diminished pleasure, is a core feature of major depressive disorder and is often present long before the diagnosis of depression. Most previous studies have investigated anhedonia with self-report measures of trait anhedonia or with behavioral paradigms using laboratory stimuli, and the real-time characteristics of hedonic processing in subclinical depression remain under-investigated. We used the experience sampling method to evaluate momentary experience of hedonic feelings in the context of daily life. Dysphoric (n = 49) and non-dysphoric (n = 51) college students completed assessments of their current positive affect (PA), as well as state anticipatory and consummatory pleasure, 3 or 4 times a day every day for 2 weeks. The results showed that dysphoric individuals reported less state anticipatory and consummatory pleasure compared with non-dysphoric individuals. Moreover, significant time-lagged associations between anticipatory pleasure and follow-up consummatory pleasure were found in the whole sample, after adjustment for current PA. The current findings thus hold considerable promise in advancing our understanding of anhedonia as well as the important role of state anticipatory pleasure in relation to depression.
摘要：
Previous studies have documented that mindfulness was positively correlated with favorable sleep quality, however, the underlying mechanisms are largely unknown. The present study examined the mediating role of rumination and the moderating role of self-control in the association between mindfulness and sleep quality. A sample of 1196 adolescents completed a battery of self-report questionnaires measuring mindfulness, rumination, self-control and sleep quality as well as demographic information. Results showed that, in addition to the negative link between mindfulness and poor sleep quality, mindfulness was negatively associated with rumination, which in turn was positively associated with poor sleep quality. The direct link between mindfulness and poor sleep quality and the indirect link through rumination were both moderated by self-control. These two effects were stronger for adolescents with low self-control than for those with high self-control. These results coincide with the antagonistic interaction hypothesis of the protective-protective model, and indicate that mindfulness and self-control, as two important protective factors of adolescents, may mutually compensate. Limitations and implications are discussed.

摘要：
With the popularity of social networking sites (SNSs), the problems of SNS addiction have been increasing. Research has revealed the association between SNS addiction and irrational procrastination. However, the mechanism underlying this relation is still unclear. The present study aimed to examine the mediating role of social networking site fatigue and the moderating role of effortful control in this link among Chinese undergraduate students. The Social Networking Site Addiction Scale, Social Networking Service Fatigue Scale, Effortful Control Scale and Irrational Procrastination Scale were completed by 1,085 Chinese undergraduate students. Results indicated that SNS addiction, SNS fatigue and irrational procrastination were positively correlated with each other, and negatively correlated with effortful control. Further analyses revealed that, SNS addiction has a direct effect on irrational procrastination. SNS fatigue mediated the relationship between SNS addiction and irrational procrastination. Both direct and indirect effects of SNS addiction on irrational procrastination were moderated by effortful control. Specifically, this effect was stronger for people with lower effortful control. These findings help clarify the mechanism underlying the association between SNS addiction and irrational procrastination, which have potential implications for intervention.

摘要：
Background: Social networking sites (SNSs), which provide abundant social comparison opportunities, are ubiquitous around the world, especially among adolescents. In China, Qzone stands out as the most popular SNS. Due to the opportunity it provides for meticulous self-presentation, SNS may give the impression that others are doing better, which is detrimental to individuals' well-being. Based on social comparison theory, the current study aimed to investigate the association between Chinese adolescents' SNS (Qzone) use and depression, as well as the mediating role of negative social comparison and the moderating role of self-esteem. Method: A total of 764 adolescents (aged 12-18 years, M = 14.23, SD = 1.75), who had an active Qzone account, were recruited voluntarily to complete questionnaires on Qzone use intensity, negative social comparison on Qzone, self-esteem, and depression. Results: More intense Qzone use was associated with higher level of negative social comparison on Qzone, which fully mediated the association between Qzone use and depression. Moreover, the mediating effect of negative social comparison on Qzone was moderated by self-esteem. The specific link between Qzone use and negative social comparison was weaker among adolescents with high self-esteem than those with low self-esteem. Limitations: As all the data in this study were self-reported and cross-sectional, causal associations cannot be identified. Additionally, the specific activities on SNS were not identified. Conclusions: Negative social comparison may be a key factor and mechanism accounting for the positive association between SNS use and depression, while self-esteem could protect adolescents from the adverse outcome of SNS use.
