This study examined the mechanism through which online support group (OSG) participation may promote patient empowerment among 340 individuals living with HIV/AIDS. Results from structural equation modelling revealed that greater use of OSGs was associated with more frequent occurrence of the empowering processes as measured by receiving useful information, receiving social support, finding positive meaning and helping others. Receiving useful information and finding positive meaning were related to higher levels of adaptive coping and lower levels of maladaptive coping, while receiving social support and helping others were related to higher levels of self-care self-efficacy, which in turn was related to higher levels of adaptive coping, and lower levels of maladaptive coping. Finally, higher levels of maladaptive coping were related to poorer quality of life, while higher levels of adaptive coping were related to better quality of life. Results suggest that OSG participation may offer some benefits for those living with HIV/AIDS.  相似文献

Although Linhares and Freitas (2010) have failed to characterize earlier experimental work in chess skill accurately, their conceptual approach of “experience-recognition”-driven problem solving points to the need to incorporate analogical reasoning mechanisms into explanations of how chess players choose the best move in chess. The Lane and Gobet (2011) commentary and the cognitive simulation models that they espouse consist of plausible mechanisms to support choosing a good move, but need additional development to incorporate abstract/semantic information. One possible avenue for future exploration will be to produce hybrid models that use both “piece-on-square” chunk and template representations and abstract high-level representations to guide search in chess.  相似文献

This study investigated the reciprocal relationship between perceptions of psychological contract fulfilment and employee performance (sales made and sales targets), and whether this was moderated by the quality and length of the social exchange relationship captured, respectively, through perceived organizational support (POS) and organizational tenure. We used a sample of 146 sales advisors and a four‐point longitudinal design and found support for reciprocal links where performance predicted subsequent psychological contract fulfilment and vice versa. The strength of the relationship between performance and psychological contract fulfilment increased over time. The quality of the social exchange relationship (i.e., POS) moderated reciprocal links between sales made and sales targets met and perceptions of psychological contract fulfilment at earlier, but not later, time points. One way to interpret the findings is the changing nature of the unfolding relationship between support, psychological contract fulfilment, and performance, where a supportive relationship buffers failing to deliver at earlier time points, but at later time points employee performance and psychological contract fulfilment associate more strongly as both parties prioritize delivery.  相似文献

This paper reports findings from a survey into applicant reactions of working adults in Saudi Arabia. A sample of 193 participants from four job functions was obtained, with measures of organizational attractiveness, core‐self evaluation, and applicant reactions to four popular selection methods in the country – interviews, résumés, work sample tests, and references – being included. Findings indicate a notably similar pattern of preference reactions to previous studies in other (Western) countries, affirming arguments for so‐called reaction generalizability. Work sample tests were rated the most favorably followed by interviews, résumés, and references. For specific procedural dimensions, résumés were perceived as the most favorable, followed by work sample tests, interviews, and references. Several significant differences were found across job functions, mostly for interviews and résumés. Significant effects were found between reactions and organizational attractiveness, and between reactions and core‐self evaluation, including some interaction effects. Implications for future research and for practice in employee selection are considered in the conclusion.  相似文献

This study examines the evaluation of innovation in a wider competency framework and within a 360‐degree rating procedure among managerial‐level job holders. The total sample of 2,979 individuals consisted of 296 target employees and their 318 bosses, 1208 peers, 828 direct reports, and 329 others who provided ratings on a competency framework. The results showed significant differences in innovation‐related competence ratings between different raters. Self‐ratings were significantly lower compared to the overall observer ratings and were correlated only with peer ratings. Different patterns of results were found for the lower and upper quartiles based on self‐ratings. For instance, no correlations were observed between self‐ratings and the ratings of any observers in the group of best self‐rated individuals. Implications for practice and future research in assessment and evaluation of innovation are discussed in conclusion.  相似文献

In 2 studies, we examined the use of validity screening items in adolescent survey data. In each study, adolescent respondents were asked whether they were telling the truth and paying attention in answering survey questions. In Study 1 (N = 7,801), the prevalence rates of student risk behaviors were significantly lower after inappropriate (invalid) responders were screened out of the sample. In addition, confirmatory and multigroup factor analyses demonstrated significant differences between the factor structures of school climate scales with valid versus invalid responders. In Study 2, student perceptions of school climate were correlated with teacher perceptions in 291 schools. A bootstrap resampling procedure compared the correlations obtained with valid versus invalid responding students in each school and found that valid responders had more positive views of school conditions and produced higher correlations with teacher perceptions. These findings support the value of validity screening items in improving the quality of adolescent survey data.  相似文献

Parkinson's disease (PD) is a progressive neurodegenerative disease primarily characterised by motor symptoms. However, another feature of PD which is receiving increasing attention is the phenomenon of impulse control disorders (ICDs), such as pathological gambling. To date, research into ICDs in PD has centred on a biomedical model of cause, related to the effects of dopamine replacement therapy. However, there are several areas of discrepancy in the current biomedical account of ICDs in PD. In addition, we argue that social and psychological factors also need to be considered to achieve a more complete understanding of the phenomenon. We present a novel conceptual model which combines biomedical and psychosocial factors in the genesis of ICDs in PD and use the model to identify a number of potential treatment intervention points and to highlight important outstanding questions concerning the inter-relationship between psychosocial and biomedical factors in the genesis of ICDs in PD.  相似文献

This study explored the basis of self-sacrificial prosocial behavior in small groups. Seventy-eight undergraduates (39M, 39F) filled out a thirty-item personality scale and then participated in a "group problem-solving study" in which the monetary success of a three-person group depended upon one of its members volunteering to endure pain (a cold stressor test) and inconvenience (being soaked in a dunk tank). There were 13 groups consisting of two females and one male, and 13 groups consisting of two males and one female. Across groups, the behavior of the altruist was judged to be more costly, challenging, and important and he/she was liked better, rewarded with more money, and preferred as a future experimental partner. Groups containing two males showed more evidence of competition to become altruists than groups containing two females, and personality traits were more effective predictors of altruistic behavior in males than in females. We conclude that competition between males and "showing off" are key factors in triggering self-sacrificial altruistic behavior.  相似文献
