Tenacious goal pursuit and flexible goal adjustment: explication and age-related analysis of assimilative and accommodative strategies of coping 总被引:6,自引:0,他引:6
Crises and critical life transitions activate 2 distinct but complementary modes of coping, (a) transforming developmental circumstances in accordance with personal preferences (assimilative tendency) and (b) adjusting personal preferences to situational constraints (accommodative tendency). Assimilative and accommodative tendencies were measured by a questionnaire comprising 2 independent scales (Tenacious Goal Pursuit and Flexible Goal Adjustment). Both scales predict high life satisfaction and low depression and are positively related to generalized internal control beliefs. The scales evinced an opposite relation to age: Cross-sectional analyses on a sample of 890 Ss in the age range from 34 to 63 years revealed a gradual shift from an assimilative to an accommodative mode of coping. Implications for theories of depression and successful aging are discussed. 相似文献

The purpose of this paper is twofold. First, it provides an historical overview of studies of risk, risk perception, and decision making under risk within the genetic counseling domain. Second, it proposes an alternative conceptualization and operationalization for the study of risk perception. The conceptualization involves probability, adversity, incompleteness, and ambiguity. Prior studies of risk perception focus on the recurrence risk and operationalize risk perception by asking for interpretations of the magnitude of the probability of the outcome. Their focus is on the probability of a particular outcome. We formulate the problem in terms of a gamble and suggest that risk perception be operationalized in terms of the riskiness of the gamble. Our focus is on the riskiness of a decision option which entails two or more outcomes. 相似文献

This study explored one mechanism through which acute disaster stress (injury, life threat, property damage, loss) may produce lasting psychological distress (depression, anxiety, somatization, hostility). More specifically, the study examined the mediating roles of seven domains of chronic stress (marital, parental, filial, financial, occupational, ecological, physical) within a sample of 930 disaster victims and controls. The results provided strong support for the hypothesis that chronic stress mediates the long-term effects of acute disaster stress on psychological distress. The main effects of loss, though limited in strength, were completely explained by victims’ higher financial, marital, filial, and physical stress. The effects of injury, though quite strong, were largely mediated by these same domains of chronic stress. Likewise, the effects of life threat were largely mediated by all these domains plus ecological stress. A mediational model was not appropriate for understanding the consequences of property damage because it did not exhibit a main effect on psychological distress. 相似文献

Because they were participating in a concurrent panel study, 222 older adults had been asked how much help they would expect to receive in a hypothetical emergency before experiencing two separate floods. For the subsample suffering losses or injuries during the floods, Study 1 examined the accuracy of their expectations, as well as possible changes in them, as a result of help actually received. Generally, victims received much less help than they had expected to receive prior to the floods. Preflood expectation of support predicted help from kin, whereas loss and education predicted help from nonkin sources. However, subsequent expectations did not change as a result of the level of help received. Using the total sample, Study 2 examined the broader issue of whether the disaster itself affected subsequent perceptions of support. Flood exposure, as measured at both individual and community levels, was associated with declines in perceptions of support and social participation. 相似文献
