A community-based sample of disadvantaged African American women (n = 445) was recruited to participate in 1 of 3 theoretically driven experimental interventions based on either the theory of gender and power, social learning theory, or cognitive behavioral theory. Intervention outcomes were compared with a waiting list control condition. From baseline to postintervention, women in the experimental interventions showed differential change on cognitive indices (knowledge and attitudes) and skill acquisition (partner negotiation skills, correct condom application, lubricant selection, and information-provision to social networks) whereas control participants were unchanged. Women in the 3 experimental interventions also completed follow-up assessments for 1 year following the interventions. In all 3 experimental conditions, condom use increased relative to the control group and there were no differences between the experimental interventions. Women who participated in one of the theoretically grounded interventions continued to increase condom use over the following year. Women entering new relationships reported significantly more condom use than did women who remained in ongoing relationships. The findings suggest that intervention models that have proven effective for women who engage in high-risk behavior may be less effective for women in established relationships for whom risk is primarily derived from the extrarelationship behavior of their partners.  相似文献

OBJECTIVE: To examine the long-term efficacy of both fear-inducing arguments and HIV counseling and testing at encouraging and maintaining knowledge about HIV transmission and prevention, as well as condom use. DESIGN: Analyses were conducted with a sample of 150 treatment groups and 34 controls and included measures of change at an immediate follow-up and a delayed follow-up. MAIN OUTCOME MEASURES: The main outcome measures were perceived risk of HIV infection, knowledge about HIV, and condom use. RESULTS: Results indicated that receiving fear-inducing arguments increased perceptions of risk at the immediate follow-up but decreased knowledge and condom use, whereas resolving fear via HIV counseling and testing decreased perceptions of risk and increased knowledge and condom use at both the immediate and delayed follow-ups. The effects on perceived risk [corrected] decreased over time, but the effects on knowledge [corrected] condom use became more pronounced. CONCLUSION: Inducing fear is not an effective way to promote HIV-relevant learning or condom use either immediately following the intervention or later on. However, HIV counseling and testing can provide an outlet for HIV-related anxiety and, subsequently, gains in both knowledge and behavior change immediately and longitudinally.  相似文献

OBJECTIVE: Most models of health behavior change applied to condom use behavior have focused on individual differences in theoretical constructs to explain condom use or nonuse, while ignoring the possibility that day-to-day within-person changes in these constructs may contribute to understanding behavior. The goal of the present study was to investigate day-to-day variability in condom use attitudes, self-efficacy, and behavioral intentions and assess the utility of this variability in predicting the likelihood of condom use each day. DESIGN: A 30-day Web-based structured daily diary was used to collect daily reports of sexual behaviors and data on theoretical predictors of condom use behavior from sexually active college students (N = 116). MAIN OUTCOME MEASURES: The authors investigated whether condom use attitudes, self-efficacy, and behavioral intentions vary day to day; whether this within-person variability predicts condom use behavior; and whether negative affective states explain this variability. RESULTS AND CONCLUSIONS: Within-person variability was found for each of the constructs. Within-person day-to-day changes in behavioral intentions and attitudes predicted the instances in which an individual used a condom and daily negative affect partially explained within-person day-to-day changes in behavioral intentions and self-efficacy. Implications for models of health behavior change and for behavior change interventions are discussed.  相似文献

This meta-analysis examined the validity of various theoretical assumptions about cognitive and behavioral change following a communication recommending condom use. The synthesis comprised 82 treatment and 29 control groups included in 46 longitudinal reports with measures of perceived severity and susceptibility, attitudes and expectancies, norms, perceptions of control, intentions, knowledge, behavioral skills, or condom use. Results indicated that across the sample of studies, communications taught recipients about facts related to HIV and also induced favorable attitudes and expectancies, greater control perceptions, and stronger intentions to use condoms in the future. Moreover, messages that presented attitudinal information and modeled behavioral skills led to increased condom use. Results are discussed in the context of theories of human behavior and change and in reference to HIV-prevention interventions.  相似文献

Theories are needed to explain and predict health behavior, as well as for the design and evaluation of interventions. Although there has been a history of developing, testing, applying, and refining health behavior theories, debates and limitations in evidence exist: The component of theories which, for example, predicts change should be better elaborated so that we can more easily understand what actually drives behavior change. Theories need to be empirically testable in two ways. Theories need to specify a set of changeable predictors to describe, explain, and predict behavior change, and they should enable us to design an effective intervention that produces exactly those changes in behavior that are predicted by the relevant theory. To make this possible, theories need to be specified in such a way that they can be rigorously tested and falsified. Moreover, for the design of theory-based interventions it must be possible to derive change techniques from the theory and to use them to generate changes in behavior. Based on eight state-of-the-science articles that make conceptual and empirical contributions to the current debate on health behavior theories, various approaches are discussed to gain further insights into explaining and changing health behaviors and the iterative process of theory development.  相似文献

OBJECTIVE: To examine the effectiveness of 2 condom promotion videotapes on self-efficacy, intentions, and behavior. DESIGN: Two hundred twenty college students completed social-cognitive and behavioral measures and were then randomly assigned to receive one of two 30-min condom promotion videotapes (male or female student presenters) or to a wait-list control condition. Participants who watched 1 of the videotapes completed immediate posttest measures, and 85% of participants completed a 4-month follow-up. MAIN OUTCOME MEASURES: Self-efficacy for condom use, intentions to use condoms, use of condom during last sex, and consistent condom use over the last month. RESULTS: Participants who received either video reported greater self-efficacy to refuse to have unprotected sex and intentions than controls at follow-up. Individuals who received either video were more likely than controls to report using a condom during last sex with a regular partner, and those who watched the female presenter were more likely to report consistent condom use. CONCLUSION: Participants benefited in terms of self-efficacy and intentions from receiving either video, but both men and women benefited more in terms of condom use behavior from receiving the female video. Future research is needed to determine whether opposite-sex speaker videos could be beneficial with a larger (and more sexually active) sample and whether these effects are maintained over time.  相似文献

The highest rates of sexually transmitted infections in the U.S. occur among adolescent females. One prevention strategy promoted for sexually active adolescents is condom use: therefore, influences on correct and consistent condom use are worth examining. Because interventions and observational research into predicting and increasing condom use have yielded mixed results, we hypothesized that a theoretically driven model incorporating female adolescents' perceptions about partner sentiments along with their own perceptions, intentions, and behaviours would improve condom use predictions. We also measured condom use errors and consistency for a more precise estimate of effective use than is common in the literature. In three structural equation models tested on a sample of 519 female adolescents, we found that intentions were associated with both correct and consistent condom use; that females' expectancy beliefs about condom use were associated with intentions; and that females' expectancy beliefs about partners' sentiments reduced the impact of their expectancy beliefs about condom use. The implications of these relations upon condom use correctness and consistency are discussed with respect to informing interventions, among other future research.  相似文献

Risk reduction interventions that promote condom use, a vital component of most HIV prevention interventions, have been successful in increasing condom use among African American adolescents. Understanding theoretical components that lead to behavior change and selecting relevant risk reduction messages remain important considerations for targeting new interventions and tailoring existing interventions. The present study sought to (1) identify the most important theoretical determinants of condom use intention in African American adolescent males and females, separately, using the integrative model of behavior prediction, and (2) identify underlying beliefs within the determinants that were good candidates for message development in similar interventions. Using 446 African American adolescents, multi‐group SEM indicated that the gender‐specific IM exhibited a better fit than the overall model. Specifically, the IM had a stronger capacity for predicting condom use intention and condom use behavior for adolescent boys. Using a specific criteria for message selection, specific condom use beliefs were discussed as potential candidate messages for both African American males and females.  相似文献

The authors assessed the relative impact of structural and social influence interventions on reducing sexually transmitted infections (STIs) and HIV risk behavior among female sex workers in the Philippines (N = 897). Four conditions included manager influence, peer influence, combined manager-peer influence, and control. Intervention effects were assessed at the establishment level in multilevel models because of statistical dependencies among women employed within the same establishments. Control group membership predicted greater perceived risk, less condom use, less HIV/AIDS knowledge, and more negative condom attitudes. Combination participants reported more positive condom attitudes, more establishment policies favoring condom use, and fewer STIs. Manager-only participants reported fewer STIs, lower condom attitudes, less knowledge, and higher perceived risk than peer-only participants. Because interventions were implemented at the city level, baseline and follow-up city differences were analyzed to rule out intervention effects due to preexisting differences.  相似文献

Examined factors associated with condom use in a community-based sample of 423 sexually active African American women. Measures were selected to reflect the components in prevailing models of health behavior. Condom users were higher on AIDS health priority, prevention attitudes, stage of change, behavioral intentions, reported more frequent and comfortable sexual communication with partners, perceived greater partner and peer approval for condom use, and reported that peers also used condoms. Women in exclusive relationships evidenced earlier stage of change, lower intentions to use condoms, fewer peers who engaged in preventive behaviors, perceived themselves to have lower risk, and had lower rates of condom use, higher education, and family income. Women in fluid relationships were at particularly high risk, with lower rates of condom use relative to women not in a relationship and greater sexual risk for HIV. Implications for HIV-risk reduction interventions with African American women are discussed.  相似文献

In 1990, psychologists compared data on 42 student teachers at the University of Zimbabwe who underwent an information-based health education session designed to increase condom use with data on 42 other student teachers who underwent a skills-based health education session. They wanted to determine whether skills-based, participative interventions are more effective in changing attitudes toward AIDS and practices than are information interventions. Mean age for all student teachers was 23.1 years. All participants completed a questionnaire before the interventions and the same questionnaire 4 months after the interventions. The 1-hour information-based intervention included a talk about HIV transmission and prevention and a question and answer period after the talk. A condom fitting demonstration, individual practice, group formulation of behavioral self-management approaches, sketches of social and assertiveness skills used to negotiate condom use, pair role plays, group psychodrama about effects of AIDS, and a video about a popular African musician with AIDS comprised the 90-minute skills-based, participative intervention. The skills-based group exhibited more knowledge about condoms and their correct use (p.001), higher self-efficacy (p.05), fewer obstacles to condom use (p,05), and fewer acts of intercourse without condom use in the last 30 days (p.05) than the information-based group. These results were especially encouraging because risk reduction behaviors were maintained over 4 months. Thus more skills-based interventions and skilled AIDS educators are needed in Africa. The few psychologists in Africa can train educators, design training programs and manuals, and develop effective support and supervision systems.  相似文献

This prospective study examined how the feelings of regret and self-blame one anticipates after engaging in unsafe sex affect condom use in new sexual relationships. The central theoretical question is whether self-efficacy perceptions can moderate the relationship between anticipated feelings and actual condom use. Consistent with theories of anticipated regret and social cognitive learning, participants were most likely to use condoms between the first and second waves of data collection when they anticipated negative feelings as a result of not using condoms (and positive feelings after having used condoms), particularly when they also believed that they had the power to exercise control over the sexual situation (high self-efficacy). The implications for interventions aimed at promoting safer sex are discussed.  相似文献

This study examined the effects of 2 HIV prevention interventions on condom use and mediators of condom use. College students were randomly assigned to a control condition or an intervention (communication skills or technical skills). Those who received either intervention had greater condom use self-efficacy, more positive condom use attitudes, and stronger intentions to use condoms than did controls. Furthermore, 3-month follow-up data revealed that students in either intervention who were not in a steady dating relationship reported more consistent condom use than did those in the control condition, whereas students who were in either intervention and in a relationship reported somewhat less consistent condom use than did those in the control condition. Analyses suggested that effects of the interventions on condom use were mediated by increased intentions to use condoms.  相似文献

According to prospect theory (A. Tversky & D. Kahneman, 1981), messages advocating a low-risk (i.e., easy, low-cost) behavior are most effective if they stress the benefits of adherence (gain framed), whereas messages advocating a risky behavior are most effective if they stress the costs of nonadherence (loss framed). Although condom use is viewed as a low-risk behavior, it may entail risky interpersonal negotiations. Study 1 (N = 167) compared ratings of condom use messages advocating relational behaviors (e.g., discussing condoms) or health behaviors (e.g., carrying condoms). As predicted, loss-framed relational messages and gain-framed health messages received higher evaluations. Study 2 (N = 225) offers a replication and evidence of issue involvement and gender as moderators. Results are discussed with reference to the design of condom use messages.  相似文献

This meta-analysis tested the major theoretical assumptions about behavior change by examining the outcomes and mediating mechanisms of different preventive strategies in a sample of 354 HIV-prevention interventions and 99 control groups, spanning the past 17 years. There were 2 main conclusions from this extensive review. First, the most effective interventions were those that contained attitudinal arguments, educational information, behavioral skills arguments, and behavioral skills training, whereas the least effective ones were those that attempted to induce fear of HIV. Second, the impact of the interventions and the different strategies behind them was contingent on the gender, age, ethnicity, risk group, and past condom use of the target audience in ways that illuminate the direction of future preventive efforts.  相似文献

An integrated theoretical model using constructs from multiple behavioral models was applied to understand and predict condom use among a sample of injecting drug users, commercial sex workers, men who have sex with men, and multipartnered heterosexuals. Elicitation interviews were conducted to develop a questionnaire to measure model constructs that may be predictive of condom use for sex with vaginal, anal, and oral regular and casual partners. A prospective survey design was used, with 993 participants interviewed at Time 1, and 686 returning for Time 2 interviews 3 months later. Regression analyses were conducted using Time 1 measures to predict intention and Time 2 behavior. Strong support was found for a model that includes attitude, social norm, and facilitators/constraints as predictors of behavior, with multiple correlations in the 0.20 to 0.40 range. Findings also indicate perceived control and facilitators/constraints are distinct constructs and both, along with attitude and social norm, contribute to explaining behavioral intention. Implications for intervention development are discussed.  相似文献

The present study used two social-psychological theories of attitude-behavior relationships to investigate condom use by college undergraduates. One purpose of the present research is to provide information for public health practitioners to better design theory-based interventions to reduce the incidence of STD's by increasing the use of condoms. Another purpose is to compare the relative usefulness of two attitude-behavior models in predicting condom use. The Fishbein and Ajzen theory of reasoned action (Ajzen, 1988; Fishbein & Ajzen. 1980) was compared with a version of Triandis' theory of attitude-behavior relations (Triandis, 1977). Of major interest was whether variables in this version of the Triandis model increased the explanatory power of the Fishbein and Ajzen model in the prediction of condom use intention and behavior. In addition, specific outcome beliefs and normative beliefs held by subjects were used to predict condom use. One hundred and ninety college undergraduates were given a questionnaire designed to measure the components of the two models. Three months after completing the questionnaire, subjects were contacted by phone to record the subject's frequency of condom use (if the subject reported having had intercourse) during the 3-month period between initial assessment and follow-up. In the prediction of intention to use a condom, results indicate that one variable from the Triandis model, personal normative beliefs, increases the explanatory power offered by the expectancy value and normative belief components of the Fishbein and Ajzen model. In the prediction of reported condom use during the 3-month follow-up period, two variables from the Triandis model—perceived susceptibility and AIDS fear—significantly increased the predictive power of the Fishbein and Ajzen model. Based on these results, the authors propose an alternative model to explain undergraduate condom use. The implications of these findings for public health interventions to encourage the use of condoms is discussed.  相似文献

For those planning interventions based on social cognition models, it is usually not clear what impact on behaviour will follow from attempts to change the cognitions specified in these models. We describe a statistical simulation technique to assess the likely impact of health promotion targeting Theory of Reasoned Action (TRA)-based predictors of condom use. We apply regression-based simulation techniques to data from the SHARE project (n?=?756 Scottish adolescents) to assess the potential impact of changes in cognitions on condom use. Results support the predictive utility of TRA-based models of psychological antecedents of condom use but also provide a cautionary warning about the magnitude of behaviour change likely to be achieved by interventions based on such models.  相似文献

Women are becoming infected with HIV via heterosexual activity at an accelerating rate, both in the United States and globally. Although a number of evaluations of behavioral risk-reduction interventions for women have been reported, many suffer from methodological problems that weaken confidence in their findings, and furthermore it is clear that many women are unable to respond to the interventions that have been tested. Most women infected through heterosexual activity are infected by their primary partner, yet achieving consistent condom use with this partner can be highly challenging for women. The present article presents recent work and innovative ideas for intervention strategies that may be more feasible, and thus more effective, for women at risk for HIV infection by their primary male partner.  相似文献

Behavior analysis has produced a robust theoretical analysis of the contingencies involved in cultural evolution. Yet, thus far, the empirical yield of this work remains quite limited. With this paper, I attempt to provide specific examples of the ways to advance an experimental analysis of the contingencies involved in cultural evolution. I begin with a review of the theoretical analyses developed by behavior analysts and other contextually oriented scientists. Next, I submit that, if the goal of our science is both predicting and influencing cultural phenomena, we must produce experimental analyses of the impact of meta-contingencies on organizations’ practices. There is no more pressing reason for doing this than the threat of climate change posed by the continuing growth in human use of fossil fuels. Therefore, the paper provides an analysis of the contingencies influencing organizational practices now affecting continued use of fossil fuels and the contingencies for organizations seeking to prevent their use. One concrete step to advance a science of cultural change relevant to climate change would be to create a database of organizations that are promoting vs. working to prevent fossil fuel consumption and the consequences that seem to maintain their practices. I call for experimental analysis of the impact of altering consequences for these practices and for experimental analyses of interventions intended to change the norms, values, and behavior of organizational leaders who can influence fossil fuel consumption. I then discuss the role of prosocial behavior and values in affecting behavior relevant to reducing fossil fuel consumption because the empirical evidence shows that prosociality favors more “green” behavior. Recent advances in prevention research have identified interventions to promote prosociality, but we need experimental analyses of how advocacy organizations can be more effective in getting these interventions widely adopted.  相似文献
