Resilience has been associated with a markedly decreased chance for risky behaviors following a trauma or other negative life event. This study examined the factor structure and psychometric properties of a self-report measure of resilience, the Suicide Resilience Inventory-25 (SRI-25; Osman et al., 2004 ), among psychiatric inpatient adolescents. In Study 1, we conducted confirmatory factor analysis to provide additional empirical support for the structure and invariance of the 3-factor model of the SRI-25 in youth samples, ages 14 to 17 years (N = 152 boys, 220 girls). Scale reliability analyses provided good evidence for internal consistency reliability of scores on the SRI-25 total and scales. In Study 2 (N = 30 boys, 40 girls), we presented data in support for the concurrent validity (i.e., known groups) of scores on the SRI-25. Additionally, we identified potential correlates for the SRI-25 total scale scores.  相似文献

Benefits and costs on prospective memory performance, of enactment at encoding and a semantic association between a cue-action word pair, were investigated in two experiments. Findings revealed superior performance for both younger and older adults following enactment, in contrast to verbal encoding, and when cue-action semantic relatedness was high. Although younger adults outperformed older adults, age did not moderate benefits of cue-action relatedness or enactment. Findings from a second experiment revealed that the inclusion of an instruction to perform a prospective memory task led to increments in response latency to items from the ongoing activity in which that task was embedded, relative to latencies when the ongoing task only was performed. However, this task interference 'cost' did not differ as a function of either cue-action relatedness or enactment. We argue that the high number of cue-action pairs employed here influenced meta-cognitive consciousness, hence determining attention allocation, in all experimental conditions.  相似文献

In many nondeterministic planning domains, an agent whose goal is to achieve φ may not succeed in finding a policy that can guarantee that all paths from the initial state lead to a final state where φ holds (strong solution). Nevertheless, if the agent is trying its best to achieve φ, it cannot give up. Instead, it may be inclined to accept weaker guarantees, such as having a path leading to φ from any intermediate state reached by the policy (strong-cyclic solution), or even less, such as having at least one path leading to φ from the initial state (weak solution). But the agent should choose among such different options based on their availability in each situation. Although the specification of this type of goal has been addressed before, in this paper we show how a planner based on the branching time temporal logic α-ctl can be used to plan for intuitive and useful goals of the form “try your best to achieve φ”.  相似文献

The purpose of the present study was to examine the psychometric properties of the FACES-IV in Portuguese caregivers of cancer patients. In this cross-sectional study, a sample of 214 adult children caregivers of cancer patients receiving chemotherapy, completed FACES-IV, Family Communication Scale (FCS), Family Satisfaction Scale (FSS), and Satisfaction with Social Support Scale (SSSS). Internal consistencies above .70 were found for all FACES-IV scales, except for Enmeshed and Rigid scales, as well as for the FCS, FSS, and SSSS (except for Intimacy). Strong correlations between FACES-IV and the validation scales FCS and FSS were found except for the Enmeshed and Rigid scales. Confirmatory analysis yielded an acceptable model for the six theoretical subscales. The discriminant analysis between problematic and non-problematic family systems showed results similar to the original study. These findings suggest that FACES-IV is a valid measure of family functioning in oncological family caregiving’s contexts.  相似文献

The glass-forming ability (GFA) of metallic alloys is associated with a topological instability criterion combined with a new parameter based on the average electronegativity difference of an element and its surrounding neighbours. In this model, we assume that during solidification the glassy phase competes directly with the supersaturated solid solution having the lowest topological instability factor for a given composition. This criterion is combined with the average electronegativity difference among the elements in the alloy, which reflects the strength of the liquid. The GFA is successfully correlated with this combined criterion in several binary glass-forming systems.  相似文献

Integrating insights from research examining the effect of being seen through the lens of stereotypes on academic performance and the social identity perspective, we examine the effect of perceived affirmative action admission at college entry on academic performance at the end of the first year. We propose that stereotype threat plays a crucial moderating role in determining when performance is affected. A longitudinal study of Black and Latino students at a large multiethnic university showed that perceptions of affirmative action admission negatively affected achievement among high stereotype-threatened individuals but not among low stereotype-threatened individuals. Furthermore, the results show that stereotype threat can have its effects because of concerns for the self (personal identity stereotype threat) or because of concerns for the group (social identity stereotype threat). As expected, social identity stereotype threat negatively affected the performance of individuals high in ethnic identification, whereas personal identity stereotype threat negatively affected the performance of individuals low in ethnic identification.  相似文献

Fixed-role therapy has primarily been seen as a form of individual therapy. However, Kelly 0955) suggested that it would provide an interesting and useful way of approaching group psychotherapy. This article illustrates the feasibility of Kelly's suggestion in a clinical setting. The group had 5 participants, all of whom had been referred for help with social anxiety or social phobia. Self-report measures were administered before and after group therapy, and the outcome was positive.  相似文献

What do material goods intended for personal consumption mean to community? We use the extreme example of natural disaster recovery in a community to explore this question. Our work describes how members make sense of material objects that transition from private to public possessions (damaged goods) and public to private possessions (donated goods). By blending consumer and community psychology perspectives with our narratives, we employ a three-dimensional framework for analyzing object meanings: (1) material objects as agents of communitas (a shared sense of “we”), (2) material objects as agents of individualism (a focus on “me”), and (3) material objects as agents of opposition (the “we” that speaks for “me” and “us” versus “them”). This theoretical frame allows us to show how different conceptions of identity lead to conflicting meanings of objects within community, and to explain how and why object meanings shift as objects move across time and space from private to public and from scarcity to abundance. We also provide implications for coping with disasters that consider collective and individual identities as well as oppositional stances in between.  相似文献

Scientific discoveries about the dangers of smoking and antismoking actions carried out in Western countries over recent decades have progressively helped create an antismoking social norm. Nevertheless, many smokers still refuse to quit. We conducted two studies to investigate smokers' resistance to this norm as a function of their personal self‐esteem (PSE) and group‐based self‐esteem (GBSE). An initial correlational study assessed smokers' perception of the antismoking social norm, their PSE, and their antismoking attitudes. Smokers with low PSE had lower antismoking attitudes than those with high PSE when the antismoking norm was strong. The second study assessed GBSE (i.e., smokers' satisfaction as smokers) and manipulated both the strength of the antismoking norm and PSE (i.e., focus on personal weaknesses or strengths). Smokers with low PSE displayed the lowest antismoking attitudes when the antismoking norm was strong and their GBSE was high. These results show that the antismoking norm can produce paradoxical effects and suggest that the way individuals cope with stigmatization is affected by the interplay between PSE and GBSE.

In this research, we have analysed the role played by the scope of justice and belief in a just world (BJW) in discrimination against immigrants. In Study 1 (n = 185), we found that the relationship between prejudice and discrimination is mediated by a restricted view of the scope of justice. In addition, the results also showed that this mediation is moderated by BJW insofar as the mediation occurred in participants with a high level of BJW but not in participants with a low level of BJW. Studies 2 and 3 experimentally tested our prediction that the legitimising role played by the scope of justice is guided by a justice motive such as BJW. In both studies, the results showed a greater degree of discrimination against immigrants when a restricted scope of justice was considered but only when the BJW was made salient. In sum, these results introduced an innovation into the literature on the legitimation of social inequalities by demonstrating the relevant role played by the justice perceptions in discrimination against immigrants.
