This study examined the variables that predicted completion of an AMEND-Emerge-based program designed to treat men (n = 202) who had engaged in intimate partner violence and the rates of recidivism among those who completed versus those who failed to complete the program. Data were collected from an archival database that housed historical and demographic data on each participant; recidivism was determined by accessing publicly available court records, and was defined very broadly as any charges filed within a year after participating in the program. Overall recidivism for this sample was low (22.28%). Demographic factors demonstrated to correctly classify post-treatment recidivism included age, race, and relationship status. Whereas those who completed the program had lower recidivism than non-completers, the differences between those groups in age, race, and relationship status suggest that features of the program may not address the needs of younger African Americans who are not married.  相似文献

Using an experimental design that measures participants’ actual behavior, this study tests the inclusion of a perceived outgroup in an advertisement for a well-established brand to determine if political orientations interact with an advertisement’s content to predict consumption of that product. The results indicate that an advertisement’s activation of one’s political orientation can either change or reinforce brand loyalty. Specifically, more conservative individuals responded to the presence of Muslim and Arab individuals in a Coca-Cola advertisement by selecting Pepsi products despite their initial preference for Coca-Cola; whereas, more liberal individuals maintained their initial brand loyalty to Coca-Cola.  相似文献

Although factors shaping sibling relationships and the developmental dynamics of such consanguinity have been addressed by various scholars, investigations questioning how the risky behaviors of one sibling, specifically substance abuse, may impact brothers versus sisters are few. The current study explored non–substance-abusing siblings’ reports of their mood, attitudes, feelings of social support, and emotions if one of their brothers or sisters was perceived to be a substance abuser. Surprisingly, 22% of a college-aged convenience sample (N = 312) described one or more of their siblings as a substance abuser and reported being exposed to drugs at an earlier age than their non–substance-abusing counterparts, in addition to other differences. Sisters, more than brothers, were also affected. These exploratory findings, although limited by potential sampling bias, highlight potential areas for future research that could clarify and perhaps improve the experience of the “forgotten” siblings in a risky family constellation.  相似文献

In Memory: A Philosophical Study, Bernecker argues for an account of contiguity. This Contiguity View is meant to solve relearning and prompting, wayward causation problems plaguing the causal theory of memory. I argue that Bernecker’s Contiguity View fails in this task. Contiguity is too weak to prevent relearning and too strong to allow prompting. These failures illustrate a problem inherent in accounts of memory causation. Relearning and prompting are both causal relations, wayward only with respect to our interest in specifying remembering’s requirements. Solving them requires saying more about remembering, not causation. I conclude by sketching such an account.  相似文献

Objectives: Attribution of symptoms as medication side effects is informed by pre-existing beliefs about medicines and perceptions of personal sensitivity to their effects (pharmaceutical schemas). We tested whether (1) pharmaceutical schemas were associated with memory (recall/recognition) for side effect information (2) memory explained the attribution of a common unrelated symptom as a side effect.

Design: In this analogue study participants saw the patient leaflet of a fictitious asthma drug listing eight side effects.

Main outcome measures: We measured recall and recognition memory for side effects and used a vignette to test whether participants attributed an unlisted common symptom (headache) as a side effect.

Results: Participants who perceived pharmaceuticals as more harmful in general recalled fewer side effects correctly (rCorrect Recall = ?.273), were less able to differentiate between listed and unlisted side effects (rRecognition Sensitivity = ?.256) and were more likely to attribute the unlisted headache symptom as a side effect (rside effect attribution = .381, ps < .01). The effect of harm beliefs on side effect attribution was partially mediated by correct recall of side effects.

Conclusion: Pharmaceutical schemas are associated with memory for side effect information. Memory may explain part of the association between pharmaceutical schemas and the attribution of unrelated symptoms as side effects.  相似文献

Objective: The aim of this study was to investigate whether problem-solving skills and perceived personal control over cancer recovery mediated the intervention effects on depression and fatigue of a web-based computer-tailored intervention for cancer survivors – the Kanker Nazorg Wijzer (Cancer Aftercare Guide).

Design: Patients were recruited through 21 Dutch hospitals (November 2013–June 2014). The mediation model was tested in a randomised controlled trial with an intervention group (n = 231) and a waiting list control group (n = 231).

Main outcome measures: Hypothesised mediators problem-solving skills (SPSI-R) and personal control (IPQ-R) were measured at baseline and 3 months from baseline. Outcomes depression (HADS) and fatigue (CIS) were measured at baseline and 6 months from baseline.

Results: The intervention effects in decreasing depression and fatigue were mediated by personal control. Problem-solving skills did not mediate the intervention effects on depression and fatigue.

Conclusion: While personal control in the control group decreased in the first three months after baseline, levels of personal control within the intervention group were maintained. This effect partially explained the intervention effects on depression and fatigue. The results provide evidence for the relevance of addressing personal control in web-based interventions in order to improve psychosocial well-being in early cancer survivors.  相似文献

This study investigated how personal goals influence age differences in episodic future thinking. Research suggests that personal goals change with age and like autobiographical memory, future thinking is thought to be organised and impacted by personal goals. It was hypothesised that cueing older adults with age-relevant goals should modulate age differences in episodic details and may also influence phenomenological characteristics of imagined scenarios. Healthy younger and older adults completed the Future Thinking Interview [Addis, D. R., Wong, A. T., & Schacter, D. L. (2008). Age-related changes in the episodic simulation of future events. Psychological Science, 19(1), 33–41. doi:10.1111/j.1467-9280.2008.02043.x] adapted to activate age-appropriate goals. Narratives were scored with an established protocol to obtain objective measures of episodic and semantic details. Subjective features such as emotionality and personal significance showed age differences as a function of goal domain while other features (e.g., vividness) were unaffected. However, consistent with prior reports, older adults produced fewer episodic details than younger adults and this was not modulated by goal domain. The results do not indicate that goal activation affects level of episodic detail. With respect to phenomenological aspects of future thinking, however, younger adults show more sensitivity to goal activation, compared with older adults.  相似文献

The State of Hawai‘i, like many other areas across the United States, has large numbers of individuals and families experiencing homelessness, many of whom seek support through statewide shelters and services. This study explored the diversity of ways in which individuals and families moved through Hawai‘i's homeless service system. Using administrative data, a cohort of new service users was tracked across time to trace the developmental trajectories of their homeless service use. The sample consisted of adults who had entered the service system for the first time in the fiscal year (FY) of 2010 (= 4655). These individuals were then tracked through the end of FY 2014, as they used emergency shelter, transitional shelter, and outreach services. A latent class growth analysis was conducted and identified four distinct patterns of service use: low service use (= 3966, 85.2%); typical transitional shelter use (= 452, 9.7%); atypical transitional use (= 127, 2.7%), and potential chronic service use (= 110, 2.4%). Multinomial logistic regression models were then used to determine if select demographic, family, background experience (e.g., education, employment), or health variables were associated with class membership. The distinct profiles for class membership are discussed.  相似文献

This comprehensive review synthesizes findings from 29 studies in which students with disabilities utilized behavioral self‐management techniques in inclusive settings. Findings suggest that consistent with 2 earlier reviews of these types of studies, most behavioral self‐management techniques continue to be adaptable in inclusive settings with moderate to strong efficacy. This review identifies strengths as well common limitations of the studies, provides recommendations for future research and practice, and includes behavioral self‐management resources.  相似文献

This study investigates the relationship between political consumerism and core political values (CPVs) among university students in Brazil (N = 414) and Germany (N = 222). Despite the prerequisite to endorse values that are compatible with political consumerism, contextual features of one's immediate environment might affect overall levels of political consumerism. Our results show that political consumerism is significantly associated with higher income in Brazil (but not in Germany). After controlling for income, political consumerism was practised more frequently in Germany than in Brazil, in urban compared with rural areas, and was not dependent on gender. The urban–rural split was stronger in Brazil than in Germany. These results confirm our hypothesis that contextual features are associated with political consumerism. Furthermore, the political value Equality positively predicted political consumerism in both countries. In contrast, Traditional Morality and support of Free Enterprise negatively predicted political consumerism, although the effect sizes of these relationships were only small. These results suggest that political consumerism among university students is widespread in Germany but not in Brazil. Interestingly, regardless of its low prevalence in Brazil, political consumerism is positively associated with the CPV of Equality among university students in both countries.  相似文献
