During middle adolescence, elevated stress and a greater presence of psychological disorders have been documented. The research has paid little attention to the regulation of positive affective states. Fredrickson's broaden‐and‐build theory suggests that cultivating positive emotions helps to build resources that boost well‐being. The current research aimed to examine the longitudinal associations between responses to positive affect (emotion‐focused positive rumination, self‐focused positive rumination, and dampening) and psychological adjustment (self‐esteem and life satisfaction) during middle adolescence. A longitudinal study with two waves separated by one year was conducted, assessing 977 adolescents (M = 13.81, SD = 0.79; 51.5% boys) with self‐report measures. A cross‐lagged panel analysis was performed by including within the same model the relationships between all of the variables in the two assessment points. The results indicated cross‐lagged positive relationships of self‐focused positive rumination with both self‐esteem and life satisfaction, while dampening showed a negative cross‐lagged relationship with self‐esteem. Moreover, higher self‐esteem predicted more emotion‐focused positive rumination, and more dampening predicted lower life satisfaction. Thus, the use of adaptive responses to positive affect and a better psychological adjustment were found to be prospectively interrelated at the one‐year follow‐up during middle adolescence. The discussion argues for the need to implement programmes to promote more adaptive responses to positive affect to enhance psychological adjustment in the adolescent transition to adulthood.  相似文献

Prospective memory (PM), remembering to remember, is crucial to everyday functioning. Understanding factors associated with PM impairments is thus important. One likely factor is rumination: a common cognitive process comprising repetitive self-focused thoughts. We investigated whether rumination is associated with impaired PM, and whether any associated impairment is exacerbated with negative stimuli. A sentence-rating task with sentences varying in valence was used with embedded PM cues in a non-clinical sample (N = 60). State rumination, two trait rumination subtypes (reflective pondering and brooding), and mood were measured in relation to PM cue detection and response times. Results showed that state rumination was associated with impaired PM cue detection and slower response times to PM cues embedded in negative sentences (not positive or neutral). Trait brooding (not reflective pondering) was associated with slower PM response times. These findings indicate that state rumination and trait brooding are associated with dissociable PM impairments.  相似文献

Risk behavior often seems ‘self-defeating’ to the observers. Most people understand the basic health-related knowledge, but some of them still choose to continue risk behaviors, especially for the young. This study aimed to examine time perspective, optimism bias and self control correlated with smoking behavior in Chinese college students. A cross-sectional survey enrolling 3016 university students in Chengdu City, Sichuan Province, China. Influence Factors were identified using multiple logistic regression analyses. Prevalence of current smoking was 20.92% (631 smokers), including 272 daily smokers (9.02%) and 359 non-daily smokers (11.90%). Future-oriented time perspective, general capacity for self-discipline, reliability and ethnicity were protective factors of smoking behavior. Possibility of self-suffering diseases and gender were risk factors of smoking behavior. Smoking in University of Chengdu, China is a severe problem. Results in this research have suggested that irrespective of the smoking level, improving health-related knowledge, time management awareness and self-control ability may contribute to reducing the prevalence of smoking behavior.  相似文献
