Predictors of Condom Use in Mexican Migrant Laborers   总被引:5,自引:0,他引:5  
The purpose of this study was to explore predictors of condom use with occasional sex partners and regular sex partners, as well as carrying condoms in a new high-risk group for HIV infection, Mexican migrant laborers. This study extends previous findings by (1) exploring additional predictors not previously examined, (2) utilizing a large sample of male and female Mexican migrant laborers, (3) carefully controlling for the effects of various demographic and lifestyle variables related to condom use, and (4) assessing the interactive effects of gender on predictors of condom use. Snowball sampling was used to survey 501 adult Mexican migrant laborers. Results revealed that condom use with occasional sex partners was predicted by carrying condoms and condom self-efficacy and that women were more likely to use condoms with occasional partners when both men and women knew someone with HIV/AIDS. Condom use with regular sex partners was predicted by procondom social norms, less negative attitudes toward condoms, not knowing someone with HIV/AIDS, and condom self-efficacy. Carrying condoms was predicted by procondom social norms, less negative attitudes toward condoms, condom self-efficacy, worry about contracting HIV/AIDS, and women were more likely than men to carry condoms when both men and women were married. Understanding these findings, future research directions, and implications for condom promotion strategies with Mexican migrant laborers are discussed.  相似文献

Four experiments were conducted to explore the mechanism of reinstatement in human causal learning. After a retroactive interference treatment in which a stimulus was first followed by an outcome (A+) and then followed by a different outcome (A*), simple exposure to the original outcome (+) in the interference-test context produced partial reinstatement of the first-learned information (A+). When exposure to the outcome took place in a context different from the interference-test context, reinstatement was not observed (Experiment 1). Equivalent results appeared when the outcome presented during reinstatement was different from the one originally related to the stimulus affected by interference, independent of whether the interfering outcome (Experiments 2, 3, and 4) or a new outcome (Experiments 3 and 4) was presented before the test. These results suggest an interpretation of reinstatement in terms of a context change between interference and testing.  相似文献

This study examined the characteristics of probabilistic classification learning, a form of implicit learning previously shown to be impaired in patients with basal ganglia dysfunction (e.g., Parkinson's disease). In this task, subjects learn to predict the weather using associations that are formed gradually across many trials, because of the probabilistic nature of the cue-outcome relationships. Patients with Parkinson's disease, both before and after pallidotomy, and age-matched control subjects, exhibited evidence of probabilistic classification learning across 100 training trials. However, pallidotomy appears to hinder the learning of associations most implicit in nature (i.e., weakly associated cues). Although subjects were most sensitive to single-cue associations when learning the task, there is evidence that cue combinations contribute significantly to probability learning. The utility of multiple dependent measures is discussed.  相似文献

The analysis of speech error corpora in various gender-marked languages has shown that noun substitutions tend to preserve grammatical gender. This result has been taken as an indication that grammatical gender could play a constraining role during the process of lexical selection. To gain insights on the status of grammatical gender in the speech production system, we discuss this hypothesis and we report three picture naming experiments. We attempted to observe gender-marked context effects in the course of error-free speech production. Participants named pictures shortly after processing a prime that was or was not gender marked and that was or was not congruent with the name of the picture. A clear congruency effect was observed, involving both facilitation in the gender congruent conditions and inhibition in gender incongruent conditions. Different interpretations of this effect and of previously reported gender context effects are discussed in the context of current models of speech production.  相似文献

Three studies found support for the notion that immigrants' acculturation to the host culture is interactively determined by their need for cognitive closure (A. W. Kruglanski & D. M. Webster, 1996) and the reference group they forge on their arrival. If such reference group is fashioned by close social relations with coethnics, the higher the immigrants' need for closure, the weaker their tendency to assimilate to the new culture and the stronger their tendency to adhere to the culture of origin. By contrast, if the reference entry group is fashioned by close relations with members of the host country, the higher their need for closure, the stronger their tendency to adapt to the new culture and the weaker their tendency to maintain the culture of origin. These findings obtained consistently across 3 immigrant samples in Italy, 1 Croatian and 2 Polish, and across multiple different measures of acculturation.  相似文献

Endogenous temporal-orienting effects were studied using a cuing paradigm in which the cue indicated the time interval during which the target was most likely to appear. Temporal-orienting effects were defined by lower reaction times (RTs) when there was a match between the temporal expectancy for a target (early or late) and the time interval during which the target actually appeared than when they mismatched. Temporal-orienting effects were found for both early and late expectancies with a detection task in Experiment 1. However, catch trials were decisive in whether temporal-orienting effects were observed in the early-expectancy condition. No temporal-orienting effects were found in the discrimination task. In Experiments 2A and 2B, temporal-orienting effects were observed in the discrimination task; however, they were larger when temporal expectancy was manipulated between blocks, rather than within blocks.  相似文献

In a continuation of work by Marjoribanks (2003), using a sample of 150 seventh grade students, relationships among Parent Involvement as defined by factor scores of four measures of parents' involvement completed by teachers: teacher-parent contacts, teacher-parent communication, parents' involvement at home, and parents' participation in school, Intellectual Ability as defined by Verbal Intelligence using the Yuste's Differential and General Aptitudes Battery-M, and Academic Grades as defined by the average grade for all subject matter were examined. Analysis showed different predictive models for children's academic achievement as a function of social status. For children of low and middle social status, Intellectual Ability was the single predictor. For children of high social status the predictors were Parents' Involvement and the interaction of Parents' Involvement and Intellectual Ability.  相似文献

The complexity of homeless service users’ characteristics and the contextual challenges faced by services can make the experience of working with people in homelessness stressful and can put providers’ well‐being at risk. In the current study, we investigated the association between service characteristics (i.e., the availability of training and supervision and the capability‐fostering approach) and social service providers’ work engagement and burnout. The study involved 497 social service providers working in homeless services in eight different European countries (62% women; mean age = 40.73, SD = 10.45) and was part of the Horizon 2020 European study “Homelessness as Unfairness (HOME_EU).” Using hierarchical linear modeling (HLM), findings showed that the availability of training and supervision were positively associated with providers’ work engagement and negatively associated with burnout. However, results varied based on the perceived usefulness of the training and supervision provided within the service and the specific outcome considered. The most consistent finding was the association between the degree to which a service promotes users’ capabilities and all the aspects of providers’ well‐being analyzed. Results are discussed in relation to their implications for how configuration of homeless services can promote social service providers’ well‐being and high‐quality care.  相似文献

We replicated and extended studies showing that contextual cues for matching stimuli from 2 separate equivalence classes control the same derived relations as contextual cues for opposition frames in RFT studies. We conducted 2 experiments with 6 college students. In Phase 1, they received training in a conditional discrimination AB. Then, they received training for maintaining AB with X1 as context, and for reversing the sample–comparison relations of AB, with X2. In Phase 2, X1 functioned as context for matching same-class stimuli, and X2 functioned as context for matching separate-class stimuli. In Phase 3, X2 controlled the same derived arbitrary relations as cues for opposition frames in RFT studies. This functional equivalence may suggest that X2 functioned as a cue for opposition frames. In Phase 4, participants matched different stimuli with X2 as context, instead of matching most different (opposite) stimuli. In addition, Different, a cue for matching different stimuli, controlled the same derived arbitrary relations as X2. These results are incompatible with X2 being a cue for opposition frames. Contextual control over equivalence and responding by exclusion can explain these outcomes. The implications of these findings for RFT studies on opposition frames are discussed.  相似文献
