Gender is one of the social structures, along with social class and ethnicity, that shapes women's smoking behaviors. We examined how different responses to gender pressures (internalization and resistance) relate to smoking. We analyzed data from a national random digit dial survey of 945 women and found that never smokers scored high on resistance to gender pressure (indicated by high scores on feminist consciousness) and on education and Body Mass Index; current smokers had the reverse pattern. Ex-smokers scored high on one measure of resistance (advertising skepticism) and on two measures of internalization (embodied femininity and weight concern); they were also likely to have high household income and to be European American. Results are discussed in terms of their implications for smoking cessation programs and antismoking campaigns.  相似文献

Pharmacologic and Behavioral Withdrawal From Addictive Drugs   总被引:1,自引:0,他引:1  
ABSTRACT— Recent theories suggest that drug withdrawal does not motivate drug use and relapse. However, data now show that withdrawal produces complex changes over time in at least two symptoms (i.e., negative affect and urges) that are highly predictive of relapse. Evidence suggests that falling levels of the drug in the blood and interruption of the drug self-administration ritual both affect these symptoms. Both of these forms of withdrawal motivate renewed drug use in addicted individuals.  相似文献

Since active messaging to targeted extraterrestrial bodies is an ongoing practice, it is difficult to see how current scientific arguments have the ability to influence actions which have independent economic and institutional structures. The article analyzes what structures of argumentation might have an effect on on-going and future METI, as well as the type of theological reflection that would likely contribute to this discussion.  相似文献

The data for this study were collected in 2014 from widows in Eastern Sri Lanka whose spouses died in the civil war, tsunami, or from health‐related problems. Conservation of resources (COR) theory was used as a lens to examine the extent to which war and tsunami‐related damages and family problems predict variation in social support, family adjustment and a perception of self‐efficacy in caring for one's family as reported by widowed women. We also investigated whether social support from the community and social support from family and friends mediated those relationships. Results of a path model fit to the data suggested variation in family adjustment to be negatively predicted by war‐related family problems and positively predicted by the social support of friends and family. Additionally, a sense of self‐efficacy in caring for one's family was found to be inversely predicted by war‐related family problems and tsunami damages. Clinical, social and theoretical implications are discussed as well as directions for further research.  相似文献

Drinking and driving is a significant health risk behavior for adolescents. This study tested mechanisms by which disinhibited personality traits (impulsivity and sensation seeking) and aspects of the adolescent home/social environment (parental monitoring and alcohol accessibility) can influence changes in drinking and driving behavior over time. Two hundred two high school age youths were assessed at 2 time points, approximately 8 months apart. Zero-inflated Poisson regression analyses were used to test (a) an additive model, where personality and environmental variables uniquely predict drinking and driving engagement and frequency; (b) a mediation model, where Time 2 environmental variables mediate the influence of disinhibited personality; and (c) an interaction model, where environmental factors either facilitate or constrain the influence of disinhibited personality on drinking and driving. Results supported both the additive and interaction model but not the mediation model. Differences emerged between results for personal drinking and driving and riding with a drinking driver. Improving our understanding of how malleable environmental variables can affect the influence of disinhibited personality traits on drinking and driving behaviors can help target and improve prevention/intervention efforts.  相似文献

Economic stress greatly increases the likelihood of mental health issues occurring within a family. Although this is widely known within the mental health profession, there is a lack of literature that assists therapists in working effectively with low-income clients. As a result, marriage and family therapists may be ill equipped to meet the needs of those in poverty, and may even be conducting therapy that is ethically unsound. The authors of this article discuss several ethical and professional issues regarding therapy with families in poverty. A number of suggestions are presented for improving the effectiveness of therapy with low-income clients. Michele E. Grimes and Alyssa D. McElwain are masters students in Marriage and Family Therapy at Purdue University Calumet, Hammond, IN. Michele E. Grimes and Alyssa D. McElwain contributed equally to this article.  相似文献

Functional magnetic resonance imaging (fMRI) has identified distinct brain regions in ventral occipitotemporal cortex (VOTC) and lateral occipitotemporal cortex (LOTC) that are differentially activated by pictures of faces and bodies. Recent work from our laboratory has shown that the strong LOTC activation evoked by bodies in which the face is occluded is attenuated when the occlusion is removed. We hypothesized that this attenuation may occur because subjects preferentially fixate upon faces when present in the scene. Here, we experimentally manipulated subjects’ fixations while they viewed a static picture of a character whose face, hand, and torso were continuously visible throughout each run. The subject’s saccades and fixations were guided by a small fixation cross that made discrete jumps to a new location every 500 ms. Subjects were instructed to follow the fixation cross and make a button press whenever it changed size. In a series of blocks, the fixation cross shifted from locations on the face, on the hand, and to locations on a background image of a phase-scrambled face. In a second study, the fixation cross moved similarly, but the hand locations were changed to locations along the character’s body or torso. A localizer task was used to identify face- and body-sensitive regions of LOTC. Body-sensitive regions were strongly activated when the subjects’ saccades were guided over the character’s torso relative to when the saccades were guided over the character’s face. Little to no activity occurred in the body-sensitive region of LOTC when the subjects’ saccades were guided over the character’s hand. The localizer task was unable to differentiate body-sensitive regions in lateral VOTC from face-sensitive regions, or body-sensitive regions in medial VOTC from flower-sensitive regions. Guided saccades over the body strongly activated both lateral and medial VOTC. These results provide new insights into the function of body-sensitive visual areas in both LOTC and VOTC, and illustrate the potential confounding influence of uncontrolled eye movements for neuroimaging studies of social perception.  相似文献

Peer supervision groups have been studied in counseling fields including psychotherapy and social work. However, limited research exists regarding genetic counselor peer supervision groups. In the present study five major research questions were investigated: (1) How prevalent is peer group supervision among genetic counselors? (2) What motivates genetic counselors to join and continue to seek peer group supervision? (3) What comprises the content, agenda, and structure of group meetings? (4) What are participants’ perceptions of group dynamics, including conflicts, cohesion, and leadership? and (5) What are the perceived benefits and limitations of participating in peer group supervision? A total of 214 genetic counselors completed an online survey, and 70 (34.8%) reported being involved currently in peer group supervision. Fifteen of these 70 respondents were interviewed regarding their experiences in peer group supervision. Inductive analysis of their responses yielded 11 domains and 37 categories. Practice implications and research recommendations are discussed.  相似文献

Various theories have proposed mechanisms for drug motivation and relapse. For instance, negative reinforcement theories focus on the alleviation of withdrawal. However, other theories and some data cast doubt on the importance of withdrawal as a motivator of addictive drug use. Using data from a randomized double-blind placebo-controlled smoking cessation treatment study (N=608), this research examined the impact of withdrawal on drug motivation and the ability to maintain abstinence. Withdrawal was experimentally manipulated by randomly assigning participants to receive active bupropion versus placebo. Mediation analyses revealed that active bupropion reduced the amount of withdrawal and craving that individuals reported in the 1st week post quit; modest support was also found for smaller declines in positive affect. These effects, in turn, were all positively associated with posttreatment abstinence. These results implicate withdrawal as an important factor in motivating persistent tobacco use.  相似文献
