Werner PD Green RJ Greenberg J Browne TL McKenna TE 《Journal of marital and family therapy》2001,27(4):459-471
In a 1996 article on family theory, we (Green & Werner) proposed that family enmeshment should not be equated with high cohesion and that the construct of enmeshment fails to discriminate between two distinct relationship processes: Closeness-caregiving and intrusiveness. In this study, our model of these two independent dimensions of family connectedness was tested by assessing spouses from 264 couples, using the California Inventory for Family Assessment (CIFA). The CIFA scales showed acceptable reliability. Significant interspouse validity correlations also were obtained. As predicted by our theory, factor analyses distinguished dimensions of intrusiveness (blurring of boundaries) from dimensions of closeness-caregiving (such as warmth and nurturance). On all but two factors, behaviors of only one spouse (but not of both) had interpretable loadings. That is, in most areas, the two spouses' behaviors did not load together to form meaningful factors. The latter finding suggests that family systems theory--with its central notion of reciprocally contingent behaviors between family members--may be useful in understanding only a few dimensions of spouses' behavior (such as reciprocal aggression) whereas personality-in-context theories may be better for understanding most other dimensions (such as warmth and nurturance). 相似文献

To investigate the role of alcohol expectancy, situational factors, and personality variables in predicting postdrinking aggression, two questionnaire studies were conducted. Subjects were randomly assigned to imagine themselves and their responses in a scenario situation, which was a combination of different beverages (soda vs. alcohol), instigation, and inhibition conditions. Both studies found significant 3-way interactions of personality aggression proneness (Buss-Durkee Hostility Inventory Assault scale) by beverage condition and by situational cue condition on subjects' reported likelihood of engaging in aggressive behavior. Expected aggression was strongly associated with greater aggression proneness in the nonalcoholic condition when there was a situational cue (low inhibition in Study 1, high instigation in Study 2) invoking aggression, but not when the situational cue was absent. This relationship between aggression proneness and expected aggression, however, was attenuated in the alcoholic drink conditions in both studies. In general, it was found that the effect of alcohol on expected aggression was minor relative to the large and significant effects of aggression proneness, instigation, and inhibition. 相似文献

Attitudinal acceptance of intimate partner violence (IPV) is an important correlate of violent behavior. This study examined acceptance of IPV using data collected from a nationally representative telephone survey of 5,238 adults. Multivariable logistic regression analyses were used to test for associations between sociodemographic characteristics, exposure to violence, question order, and acceptance of hitting a spouse or boyfriend/girlfriend under specific circumstances. Depending on the circumstance examined, acceptance of IPV was significantly higher among participants who were male and younger than 35; were non-White; were divorced, separated, or had never married; had not completed high school; had a low household income; or were victims of violence within the past 12 months. Participants were more accepting of women hitting men; they also were consistently more likely to report tolerance of IPV if they were asked first about women hitting men rather than men hitting women. Reports of IPV tolerance need to be interpreted within the context of the survey. Efforts to change IPV attitudes can be tailored to specific IPV circumstances and subgroups, and these efforts should emphasize that the use of physical violence is unacceptable to both genders. 相似文献

This prospective study examines the epidemiology of physical attack and rape among a sample of 171 not-in-treatment, crack-cocaine using women. Since initiating crack use, 62% of the women reported suffering a physical attack. The annual rate of victimization by physical attack was 45%. Overall, more than half of the victims sought medical care subsequent to an attack. The prevalence of rape since crack use was initiated was 32%, and the annual rate was 11%. Among those women having been raped since they initiated crack use, 83% reported they were high on crack when the crime occurred as were an estimated 57% of the perpetrators. Logistic regression analyses showed that duration of crack use, arrest for prostitution, and some college education were predictors of having experienced a physical attack. Duration of crack use and a history of prostitution were predictors of suffering a rape. Drug abuse treatment programs must be sensitive to high levels of violence victimization experienced by crack-cocaine using women. Screening women for victimization, and treating the problems that emanate from it, may help make drug abuse treatment more effective. 相似文献

This Issue Brief examines the 1999 contribution behavior of 1.7 million 401(k) plan participants drawn from the EBRI/ICI Participant-Directed Retirement Plan Data Collection Project. The findings in this paper build on previous academic research examining the contribution activity of 401(k) participants, by using a large sample of participants in a wide range of plan sizes and by examining in detail the factors that influence contribution activity. Eighty-five percent of participants in the sample only made before-tax contributions to their plans, and 97 percent of all dollars contributed by employees were contributed on a before-tax basis. On average, participants contributed 6.8 percent of their salaries on a before-tax basis. Before-tax contribution activity varied among participants. About 61 percent of participants contributed more than 5 percent of their salaries on a before-tax basis and about 21 percent set aside more than 10 percent of their salaries on a before-tax basis. Eleven percent of participants analyzed in this study earning more than $40,000 a year contributed at the $10,000 before-tax IRC limit in 1999. Thirteen percent of participants with salaries between $70,000 and $80,000 contributed at the cap, and 18 percent of those with salaries between $80,000 and $90,000 were at the limit. However, it appears that among participants not contributing at the IRC limit, 52 percent could not have done so because of formal plan-imposed contribution limits below the IRC limit. Older participants tended to contribute a higher percentage of their salaries to plans than did younger participants, even after factoring out differences in salary and job tenure. Participants tended to increase the share of their salary (and amounts) contributed to their 401(k) plan as their salaries rose until salaries reached $80,000. For individuals with salaries above $80,000, before-tax contribution rates (though not the amounts contributed) tended to fall as salaries rose because IRC, and possibly plan sponsor, contribution limits became binding for some participants. Giving employees the option of borrowing from their 401(k) accounts increased participant contribution rates. On average, a participant in a plan offering loans appeared to contribute 0.6 percentage point more of his or her salary to the plan than a participant in a plan with no loan provision. Total contributions--the sum of employee and employer contributions--were higher for participants who received an employer contribution as part of their 401(k) plan than for those who did not. The average total contribution rate was 10 percent of salary for employees in plans offering an employer contribution, compared with 7.4 percent for those in plans not offering an employer contribution. 相似文献

Internet use among college students: an exploratory study 总被引:36,自引:0,他引:36
Anderson KJ 《Journal of American college health : J of ACH》2001,50(1):21-26
The author and associates surveyed 1,300 college students in classrooms at eight academic institutions to identify how the students' use of the Internet has affected their social or academic lives. Although the typical Internet-using student uses the Internet for 100 minutes per day, a small group of students use the Internet to a degree that interferes with other aspects of their lives. Most of them are men and are found among the hard science academic majors. Some ideas for dealing with this problem are suggested. 相似文献
