This study examines coping in response to HIV infection, using longitudinal data from a nationally representative sample (n = 2,864) of HIV-infected persons. We investigated configurations of coping responses, the correlates of configuration membership, the stability of coping configurations, and the relationship of coping to emotional well-being. Four coping configurations emerged from cluster analyses: relatively frequent use of blame-withdrawal coping, frequent use of distancing, frequent active-approach coping, and infrequent use of all three coping strategies (passive copers). Passive copers had few symptoms, high levels of physical functioning, and high emotional well-being; blame-withdrawal copers had the opposite pattern. Of those completing a second interview 1 year after baseline, 46% had the same coping configuration. Increases in the number of HIV-related symptoms raised the probability of blame-withdrawal coping at follow-up, whereas decreases raised the probability of passive coping. Infrequent use of coping responses at baseline was related to greater emotional well-being 1 year later. This result, in conjunction with the high levels of emotional well-being in the passive cluster, suggests that high levels of distress can induce blame-withdrawal coping whereas coping efforts are minimal when social support and emotional well-being are high. Results highlight issues in ascertaining the causal direction between coping and psychological outcomes, as well as in specifying the nature of stressful situations with which people are coping.  相似文献

Conceptual (a priori) subgroups in obesity based on personality findings from the Rorschach Comprehensive System were suggested for 100 obese patients. The subgroups were further compared in terms of general anamnestic and behavioral data. The largest subgroup was Rorschach characterized by difficulties with emotions and a tendency towards depression. Demographic and behavioral data for this subgroup revealed intermediate or higher education, regular meals, eating disorders like binge eating, periodic variations in eating during the year and experiencing body size as having a psychological meaning. The other subgroup was characterized by coping liabilities and was further associated with a lower socio-economic level and irregular or chaotic meal patterns. For the group with emotional difficulties, the results suggest a more complex psychological pattern, where eating and emotions could be closely related. The group with coping liabilities could have difficulties other than emotional ones concerning food and eating, such as finding a structure for eating and making changes in lifestyle and habits.  相似文献

This study aimed to examine the effects of a career construction theory-oriented Career Adaptability Psycho-educational Programme on career adaptability and coping with career indecision in Turkish high school students. Twenty-six participants took part in the experimental design. A split-plot (mixed) design of 2 × 3 (experimental/control groups X pretest/posttest/follow-up test) was used. It was found that the Career Adaptability Psycho-educational Programme has a significant effect on coping with career indecision and career adaptability; the same effect was found for the follow-up measures completed 4 months later.  相似文献

The social distancing measures implemented to slow the spread of COVID-19 impacted many aspects of people's lives. Previous research has reported negative consequences of these measures for people's psychological well-being, and that people differed in the impact on their psychological well-being. The present study aimed to describe the different coping strategies Dutch people used to deal with these measures and to link these strategies to loneliness. In addition, the study aimed to examine mean-level changes in loneliness and to explore individual differences in loneliness change. We used data from 2009 participants of a panel study of representative Dutch households. We assessed coping strategies used during the first wave of the COVID-19 pandemic in May 2020 and examined changes in loneliness between October 2019 (before COVID-19) and May 2020 (during the first wave of COVID-19). First, results showed that most people employed specific coping strategies. The most frequently used social strategies were chatting and (video)calling; the most frequently used non-social strategies were going outside, doing chores, watching TV, reading and self-care. Second, people who used more coping strategies reported lower levels of loneliness. Third, analyses revealed an average increase in loneliness between October 2019 and May 2020. Fourth, we observed two significant interaction effects, showing a stronger positive link between the number of social coping strategies and initial loneliness levels among those with a partner or living with others than for those who were single or lived alone. Yet, no moderating effects on changes in loneliness were found: people using more coping strategies did not differ in loneliness changes from people using fewer coping strategies. Together, findings suggest that loneliness increased in the Netherlands during the first phase of COVID-19 and that, while people's coping strategies were related to loneliness levels, they did not buffer against loneliness increases.  相似文献

This research investigated how implicit theories of mental health (ITMH) influence people's experience of anxiety and depression symptoms during the COVID-19 pandemic in China. Two thousand and 44 Chinese completed the study during an emergent outbreak of the COVID-19 pandemic in Shaanxi, China. The results suggested that ITMH significantly influence people's experience of anxiety and depression symptoms. Both active and passive coping styles significantly mediated the relationship between ITMH and anxiety/depression, with active coping style as a stronger mediator than passive coping style. Implications of the current research for improving people's mental health during pandemics of infectious diseases and directions for future research are discussed.  相似文献

Numerous individuals have lost loved ones during the COVID-19 pandemic while millions of others have also experienced ongoing pervasive non-death loss. The understanding of how people deal with non-death loss is still relatively limited. Incorporating theory of coping and loss, this study examines the reciprocal relationship between non-death loss and acceptance coping. Based on the results of a cross-lagged panel model involving 314 participants in China, we found that before the end of the zero-Covid policy, non-death loss at Time 1 predicted less acceptance coping at Time 2, but in the opening up stage in late 2022, non-death loss at time 2 did not predict acceptance coping at time 3. The findings have significant implications for understanding the interplay between non-death loss and acceptance coping and highlights abrupt psychological changes during the COVID-19 pandemic.  相似文献

In China, there is an increasing demand for preschool children with autism spectrum disorder (ASD) enrolled in general education to learn English vocabulary. The purpose of this study was to evaluate the effect of foreign mand training in English on the acquisition of mand responses, and the emergence of tact and listener responses for three Chinese-speaking preschool children (boys; 4–5 years of age) with ASD. Echoic-to-mand training was implemented to teach mands in English. The study employed a concurrent multiple-probe design across behaviors. The results of the study indicated that the training was effective in the acquisition of mand responses. Moreover, untaught tacts and listener responses for the same vocabulary emerged without explicit training. Implications for small-group mand training in foreign language acquisition were discussed.  相似文献

Three experiments examined the performance of 4-year-old children in matching geometric stimuli. Performance was developed as a simulation in which all components of the behavior were overt and directly measured. A correct match depended on the state of an instructional stimulus: the background color of the display. In the first two experiments, on nonidentity trials (signified by a green background) the next longer length, larger size, or greater distance was correct. With a blue background, a comparison identical to the sample was correct. In Experiment 3, red was added for which shorter, smaller, or nearer was correct. Also here, on nonidentity trials, if a comparison of the correct length was not presented, the children adjusted their search target to the comparison of the next succeeding size (larger or smaller) so as to maintain a constant matching relation. Subsequently, when exposure to the instructional stimulus was reduced to presentation only at the beginning of each trial, performance simulated matching based on instructions about abstract relations. In all experiments, accurate matching generalized across novel stimuli and reduced exposure to the instructional stimuli.  相似文献

Interpersonally incomparable responses pose a significant problem for survey researchers. If the manifest responses of individuals differ from their underlying true responses by monotonic transformations which vary from person to person, then the covariances of the manifest responses tools such as factor analysis may yield incorrect results. Satisfactory results for interpersonally incomparable ordinal responses can be obtained by assuming that rankings are based upon a set of multivariate normal latent variables which satisfy the factor or ideal point models of choice. Two statistical methods based upon these assumptions are described; their statistical properties are explored; and their computational feasibility is demonstrated in some simulations. We conclude that is possible to develop methods for factor and ideal point analysis of interpersonally incomparable ordinal data.This research was begun in the supportive enviroment of the Survey Research Center at the University of California, Berkeley. Financial support was provided by Percy Tannenbaum, Director of the Center, by Allan Sindler, Dean of the Graduate School of Public Policy at Berkeley, by the Data Center of Harvard University, and by the National Science Foundation through grant number SES-84-03056. Chris Achen, Doug Rivers, and members of the Harvard-MIT econometrics seminar provided useful comments.  相似文献
