The effects of preoperative preparation on postoperative outcomes: The moderating role of control appraisals.

Objective: To test the proposal that external health locus of control and self-efficacy would moderate the effects of a psychological preparation for surgery on outcomes for surgical heart patients. Main Outcome Measures: Psychological distress, pain, serum cortisol, and tumor necrosis factor alpha. Design: A total of 80 coronary artery bypass graft patients were given standard care plus a psychological preparation or standard care alone using a single-blind methodology with random assignment. Data on psychological and biological functioning were collected at admission (baseline) and discharge. Results: As predicted, external health locus of control and self-efficacy moderated the effect of the preparation on all outcomes. Results indicated that for high external health locus of control, the preparation was related to lower distress for people with high self-efficacy compared with those with low self-efficacy. When external health locus of control was low, the preparation was related to lower distress for those with lower self-efficacy. Conclusion: These findings caution against the use of preparations and education for surgical patients without accounting for control appraisals.

Psychopathy and sexual assault: Static risk factors, emotional precursors, and rapist subtypes.

This study compared psychopathic and nonpsychopathic rapists on static risk factors and on emotional and motivational precursors. Sixty incarcerated rapists were assessed for psychopathy with the Psychopathy Checklist—Revised (R. D. Hare, 1991), and they were classified according to the Massachusetts Treatment Center: Revised Rapist Typology, Version 3 (R. A. Knight & R. A. Prentky, l990b). Psychopathy was positively associated with past nonsexual offenses and negatively associated with age onset for criminal offending, number of sexual victims, and the intensity of negative emotions experienced before sexual offending. However, psychopathy was not related to sexual offense history, age of onset for sexual offending, or victim harm. Last, psychopaths were most likely to be classified as opportunistic and pervasively angry rapists. The findings indicate that psychopathy should be considered when developing intervention strategies for rapists. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Social support, support groups, and the cancer patient.

Surveys the literature on social support and cancer and reports results from an empirical investigation of the factors that led cancer patients to join social support groups. Questionnaire data from 666 21–89 yr old cancer patients show that although most Ss received high levels of social support following cancer, some experienced isolated instances of rejection or did not receive the type of support they wanted from family, friends, and medical caregivers. This appeared to be 1 impetus for joining cancer support groups, although Ss reporting a lack of social support were not generally more likely to join support groups than were other Ss. The Profile of Mood States suggested that attenders were somewhat less likely to be depressed than were nonattenders. In addition, cancer support group attenders were more likely to be White middle-class females, to report having more problems, and to use social support resources of all kinds than were nonattenders. Implications for outreach to cancer patients are discussed, and it is concluded that while support groups may be beneficial for many cancer patients, current programs tend to be used largely by the same segment of the population that uses traditional mental health services.

A stitch in time: Self-regulation and proactive coping.

In a conceptual and temporal framework, derived from research on social cognition, social interaction, and stress and coping, the authors analyze the processes through which people anticipate or detect potential stressors and act in advance to prevent them or to mute their impact (proactive coping). The framework specifies five stages in proactive coping: (1) resource accumulation, (2) recognition of potential stressors. (3) initial appraisal, (4) preliminary coping efforts, and (5) elicitation and use of feedback concerning initial efforts. The authors detail the role of individual differences, skills, and resources at each stage. They highlight the unique predictions afforded by a focus on proactive coping and the importance of understanding how people avoid and offset potential stressors.

Low Temperature Water–Gas Shift Reaction Over Alkali Metal Promoted Cobalt Carbide Catalysts

Low temperature water–gas shift (LT-WGS) was performed over various group I alkali metal (Li, Na, K, Rb, Cs) promoted cobalt carbide (Co₂C) catalysts at temperatures ranging from 453 to 573 K and atmospheric pressure. Cobalt carbide (Co₂C) was found to be active for the WGS reaction. The stability of the catalyst is related to the stability of the cobalt carbide phases under reaction conditions. Potassium promoted cobalt carbide catalysts exhibited higher activity and stability compared to the other alkali promoted catalysts for LT-WGS. X-ray diffraction analyses of fresh and used catalysts suggest that the origin of deactivation of the catalysts is primarily due to the chemical transition of cobalt from carbide to metal during WGS.     

Self-awareness, probability of improvement, and the self-serving bias.

Evidence for the self-serving bias (attributing success internally and failure externally) is inconsistent. Although internal success attributions are consistently found, researchers find both internal and external attributions for failure. The authors explain these disparate effects by considering the intersection of 2 systems, a system comparing self against standards and a causal attribution system. It was predicted that success and failure attributions are moderated by self-awareness and by the ability to improve. When self-focus is high (a) success is attributed internally, (b) failure is attributed internally when people can improve, (c) failure is attributed externally when people cannot improve, and (d) these attributions affect state self-esteem. Implications for the self-serving bias are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Adjustment to threatening events: A theory of cognitive adaptation.

Proposes a theory of cognitive adaptation to threatening events. It is argued that the adjustment process centers around 3 themes: A search for meaning in the experience, an attempt to regain mastery over the event in particular and over life more generally, and an effort to restore self-esteem through self-enhancing evaluations. These themes are discussed with reference to cancer patients' coping efforts. It is maintained that successful adjustment depends, in a large part, on the ability to sustain and modify illusions that buffer not only against present threats but also against possible future setbacks.

Correlates of household smoking bans among Chinese Americans.

No population-based data are available on the degree to which Chinese Americans have adopted smoke-free household policies and whether these policies are effective in reducing environmental tobacco smoke (ETS) exposure. The present study examines the prevalence of smoke-free home rules among Chinese Americans living in New York City, describes predictors of adopting full smoking bans in the home, and explores the association between household smoking restrictions and ETS exposure at home. In-person interviews using a comprehensive household-based survey were conducted with 2,537 adults aged 18-74 years. Interviews were conducted in Mandarin, Cantonese, and other Chinese dialects. A total of 66% of respondents reported that smoking was not allowed inside the home, 22% reported a partial ban on smoking in the home, and 12% reported no smoking ban. Among current smokers, 38% reported a full household smoking ban. Current smoking status was the strongest predictor of less restrictive household smoking policies. Knowledge of the dangers of ETS, support of smoke-free air legislation, years in the United States, gender, income, and marital status also were associated with household smoking bans. Those living with a total household smoking ban were significantly less likely to report 30-day exposure to ETS than were those living in homes with a partial ban or no ban (7% vs. 68% and 73%, respectively). In homes of smokers and nonsmokers alike, exposure to ETS remains high. Smoke-free home rules and interventions among smokers and nonsmokers to raise awareness of the dangers of ETS have the potential to significantly reduce exposure to household ETS among this immigrant population.
