Maintaining a satisfying heterosexual relationship is important to many individuals?? happiness and physical health. Evolutionary theories on the formation of relationships suggest that adult attachment and relationship commitment are universal mechanisms for securing and maintaining such mating relationships. This study sought to understand how these two mechanisms may link to each other and how they in turn contribute to relationship satisfaction with one??s current partner in Hong Kong Chinese and American cultures. Similarities in the model for relationship satisfaction were found among young dating couples in the United States and Hong Kong. Specifically, attachment anxiety was positively linked to structural commitment, whereas attachment avoidance was negatively related to personal commitment. Both dimensions of attachment (anxiety and avoidance) and both components of commitment (personal and structural) were found to predict current relationship satisfaction significantly and equivalently across cultures, with the pathway from attachment avoidance to current relationship satisfaction similarly mediated by personal commitment in both cultural groups. These results were interpreted in terms of a probable universal logic informing the interpersonal dynamics involving attachment and relationship commitment.  相似文献

This is the second of two articles that describe the development and evaluation of three component-specific instructional systems for improving critical reading skills. The skill components that were the focus of training have been shown in prior research to represent particular sources of processing difficulty for young adult, poor readers and, based on a model of component interaction, were predicted to have a potentially strong impact on the performance of other component processes. Part 1 presented the evaluation of SPEED, a system designed to develop automaticity in the ability to perceptually encode multiletter units that appear in words. Part 2 describes the evaluation of the RACER and SKI JUMP systems, which focus respectively on developing automaticity in phonological decoding of orthographic information in words and the use of context frames in retrieving and integrating word meanings. In both the RACER and SKI JUMP training studies, all subjects achieved highly accurate and efficient levels of performance in the skill that was the focus of training. Furthermore, SKI JUMP training had an impact on word analysis components and on a measure of inferential comprehension. An analysis of the patterns of transfer of skills acquired in training is presented, and conditions for optimizing skill integration are discussed.  相似文献

Many studies have revealed that individual differences in coping responses to the diagnosis and treatment of breast cancer are associated with psychological adjustment. The vast majority of these studies, however, focus exclusively on urban breast cancer survivors despite that rural breast cancer survivors are likely to have distinct experiences both in general and in relation to breast cancer. The current study quantitatively examined the coping strategies employed by both rural and urban breast cancer patients while they were undergoing radiation therapy. Further, the influence of these coping behaviours on concurrent as well as subsequent depressive symptoms (3 and 6 months later) was examined. The results revealed that the rurality of breast cancer patients was unrelated to the ways in which they coped, but did influence the relationships between some coping responses and depressive symptoms. Specifically, active coping and positive reinterpretation were negatively related to depressive symptoms for more rural breast cancer patients, but not their relatively urban counterparts. Similarly, behavioural disengagement was more strongly related to depressive symptoms for more rural patients. Possible reasons for this pattern of results and implications are discussed.  相似文献

Effects of behaviour change on cognitions are rarely examined within the Theory of Planned Behaviour. We tested whether increases in physical activity resulted in more positive beliefs about further change among a cohort of sedentary adults participating in a behavioural intervention trial (ProActive). At baseline, 6 and 12 months, 365 adults completed questionnaires assessing physical activity and cognitions about becoming more active over the coming year. Objective activity was assessed at baseline and 12 months. Participants reporting larger increases in activity were no more positive about making further increases than those reporting less behaviour change (p-values > 0.05). Participants with larger increases in objective activity reported weaker perceived control (β?=??0.342; p?=?0.001) and more negative instrumental attitudes (β?=??0.230; p?=?0.017) at 12 months. Participants may have felt that they had changed enough or measures of perceived success may be more sensitive to behaviour change. Alternatively, long measurement intervals may have missed immediate cognitive and affective consequences of behaviour change, or such effects may require participants to consistently self-monitor or receive feedback on performance. Future studies could test the effect of such techniques on physical activity and a wider range of cognitive, affective and physiological consequences, using more frequent measurement intervals.  相似文献

We examined whether self-affirmation would facilitate intentions to engage in colorectal cancer (CRC) screening among individuals who were off-schedule for CRC screening and who were categorised as unrealistically optimistic, realistic or unrealistically pessimistic about their CRC risk. All participants received tailored risk feedback; in addition, one group received threatening social comparison information regarding their risk factors, a second received this information after a self-affirmation exercise and a third was a no-treatment control. When participants were unrealistically optimistic about their CRC risk (determined by comparing their perceived comparative risk to calculations from a risk algorithm), they expressed greater interest in screening if they were self-affirmed (relative to controls). Non-affirmed unrealistic optimists expressed lower interest relative to controls, suggesting that they were responding defensively. Realistic participants and unrealistically pessimistic participants who were self-affirmed expressed relatively less interest in CRC screening, suggesting that self-affirmation can be helpful or hurtful depending on the accuracy of one's risk perceptions.  相似文献

Although African-Americans (Blacks) smoke fewer cigarettes per day than European-Americans (Whites), there is ample evidence that Blacks are more susceptible to smoking-related health consequences. A variety of behavioural, social and biological factors have been linked to this increased risk. There has been little research, however, on racial differences in smoking-related knowledge and perceived risk of lung cancer. The primary goal of the current study was to evaluate beliefs and knowledge that contribute to race disparities in lung cancer risk among current smokers. Data from two separate nationally representative surveys (the Health Information National Trends surveys 2003 and 2005) were analysed. Logistic and hierarchical regressions were conducted; gender, age, education level, annual household income and amount of smoking were included as covariates. In both studies, Black smokers were significantly more likely to endorse inaccurate statements than were White smokers, and did not estimate their lung cancer risk to be significantly higher than Whites. Results highlight an important racial disparity in public health knowledge among current smokers.  相似文献
