Medical information can improve health, and there is an enormous amount of health information available on the Internet. A randomized clinical trial tested the effectiveness of an intervention based on social- cognitive theory to improve information use among people living with HIV/AIDS. Men and women (N = 448) were placed in either (a) an 8-session intervention that focused on Internet information consumer skills or (b) a time-matched support group and were followed to 9 months postintervention. The Internet skills group demonstrated greater Internet use for health, information coping, and social support compared with the control group. The authors conclude that people with HIV infection may benefit from increased access to health information on the Internet and that vulnerability to misinformation and fraud can be reduced through behavioral interventions.

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.

The National Institute of Mental Health Multisite HIV Prevention Trial was a trial of an intervention to reduce sexual HIV risk behaviors among 3,706 low-income at-risk men and women at 7 U.S. research sites. The intervention, based on social- cognitive theory and designed to influence behavior change by improving expected outcomes of condom use and increasing knowledge, skills, and self-efficacy to execute safer sex behaviors, was effective relative to a control condition in reducing sexual risk behavior. At 3 months after completion of the intervention, measures of these potential mediators were higher in the intervention than in the control condition. Although the effect of the intervention on sexual risk behavior was significantly reduced when the variables were controlled statistically, supporting the hypothesis of their mediation of the intervention effect, most of the effect remained unexplained, indicating the influence of unmeasured factors on outcome.

Objective: Emotions are key predictors of sexual risk behavior but have been largely ignored in theory-based intervention development. The present study aims to evaluate whether the addition of an emotional education intervention component to a traditional social–cognitive safer sex intervention increases intervention efficacy, compared with both a social–cognitive only intervention and a no intervention control condition. Methods: Young adults were randomized in small groups to receive the social–cognitive–emotional (SCE) intervention, the social–cognitive (SC) intervention, or standard of care. Results: Analyses of data from 176 participants indicated that intervention arms reported similar increased condom use compared with the no intervention control arm at 3 months' postintervention (β = .06, p = .41, d = 0.08). However, at 6 months' postintervention, individuals in the SCE intervention arm reported increased condom use compared with both the SC intervention (β = .27, p = .04, d = 0.38) and control arms (β = .37, p  相似文献

Objective: This study sought to articulate pathways between constructs from the theory of gender and power and their associations with sexual behavior. Design: The data were collected preintervention during a randomized controlled HIV prevention trial. Participants were 701 sexually active, unmarried African American females, aged 14–20, who were not pregnant, and were recruited from three health clinics in a southeastern US city. Structural equation modeling was used for the analyses. Main Outcome Measure: Self-reported condom use. Results: Theoretical associations yielded a well-fitting structural model across initial and cross-validation samples. A significant amount of variance was explained for the variables of condom use (R2 = .31, .18), partner communication (R2 = .30, .26), substance use during sex (R2 = .32, .51), and negative personal affect (R2 = .36, .48). Partner communication (.35, .38) was the strongest predictor of condom use, negative personal affect (?.41, ?.37) was the strongest predictor of partner communication, and physical risk (.54, .54) was the strongest predictor of negative personal affect. Conclusion: This model provides evidence to support both direct and indirect associations between social and behavioral risk factors and condom use. Associations between theory of gender and power constructs and condom use can facilitate future development and analyses of interventions based on this theory.

The theory of reasoned action (TRA) provides useful information when designing health education interventions. In this study, 703 heterosexual STD clinic clients responded to a TRA-based survey. With steady partners, social norms and attitudes toward condom use were significant predictors of intention for both men and women. The interaction of attitude and norm increased prediction for men (R = .64, p < 0.001) and women (R = .70, p < 0.001). With casual partners, attitude was a predictor for men and social norm was a predictor for women. Prior use of condoms increased prediction for men (R = .38, p < 0.001) and women (R = .47, p < 0.001). Findings suggest that, in addition to traditional TRA model variables, the relationship between sexual partners and the individual's prior experience with condom use should be incorporated into attempts to understand this complex, dyadic behavior. Examining specific outcome and normative beliefs also provides important information for intervention design.  相似文献

Based on the tenets of parental investment theory, the authors postulate that there was greater pressure to inhibit potentially maladaptive emotional, social, and sexual responses on prehistoric women than men in some contexts, resulting in enhanced inhibitory abilities in women in some domains. They reviewed studies whose researchers examined gender differences on social, behavioral, and cognitive tasks involving inhibition and found gender differences favoring female humans most consistent for social tasks (e.g., control of emotions), somewhat less pronounced for behavioral tasks (e.g., delay of gratification), and weak and inconsistent for cognitive tasks (e.g., conceptual tempo). This pattern was interpreted as being consistent with the position that gender differences in inhibition are relatively domain specific in nature, with women demonstrating greater abilities on tasks related to reproduction and childrearing, which is consistent with parental investment theory.

This study compared a sample of low-income African American women in the southeastern United States who had and had not yet undergone HIV counseling and testing on risk-related cognitive mediating variables and self-reported sexual behaviors. Four hundred sixty (N = 460) African American women were recruited from health clinics and community settings in a southern city. Forty-five percent of the women (n = 207) had undergone HIV counseling and testing, whereas 55% (n = 253) had never been tested. Women who were seropositive were excluded from the analyses. After providing informed consent, the women completed a battery of cognitive mediating measures assessing AIDS knowledge, attitudes theoretically relevant to risk reduction, and self-reported sexual behavior. In addition, each participant demonstrated condom application skills using a penile model. Women who had undergone testing were younger, rated HIV disease as more serious, considered AIDS a greater health concern, had more positive attitudes toward HIV prevention, expressed greater intentions to use condoms, and evidenced a greater commitment to self-protective behavior than women who were not yet tested. Women who had undergone HIV antibody testing, however, showed no differences in sexual behavior from women who were never tested. Sexual behavior, including numbers of partners, frequency of unprotected intercourse, and inconsistent condom use, left women in both groups at significant and comparable risk for HIV and sexually transmitted disease infection. HIV counseling and testing alone may not be effective primary prevention strategies for promoting risk reduction among African American women.  相似文献

The present meta-analysis integrates the effects of randomized controlled trials that focus on promoting effective parenting in the transition to parenthood. We included 142 papers on interventions which started during pregnancy or in the first 6 months after birth. Computations were based on random-effects models. On average, interventions had small to very small significant effects on parenting (d = .35 SD units), parental stress (d = .20), child abuse (d = .13), health-promoting behavior of parents (d=.15), cognitive development (d = .24), social development (d = .30), motor development of the child (d = .15), child mental health (d = .40), parental mental health (d = .31), and couple adjustment (d = .13). Most of the effects were maintained at follow-up. Effects varied by onset of the intervention, delivery mode, qualification of the intervener, length of intervention, intervention goals, and gender distribution. In addition, we found that older studies reported greater effect sizes. We conclude that parenting-focused interventions are effective and should be made accessible to more expectant and new parents.

Substance-dependent adolescents (N?=?34) in a residential drug treatment facility received either a 6-session behavior skills training HIV-risk reduction intervention or standard HIV education. After the intervention, adolescents who received behavior skills training exhibited increased knowledge about HIV-AIDS, more favorable attitudes toward prevention and condom use, more internal locus of control, increased self-efficacy, increased recognition of HIV risk and decreases in high-risk sexual activity. Self-report data were corroborated by records for the treatment of sexually transmitted diseases. The results from this pilot demonstration effort suggest that skills training based on cognitive–behavioral principles may be effective in lowering high-risk adolescents' vulnerability to HIV infection and warrant evaluation in a controlled comparison with a larger sample.

Counseling by health care providers has the potential to increase physical activity in sedentary patients, yet few studies have tested interventions for physical activity counseling delivered in health care settings. The Activity Counseling Trial (ACT) is a 5-yr randomized clinical trial to evaluate the efficacy of two primary care, practice-based physical activity behavioral interventions relative to a standard care control condition. A total of 874 sedentary men and women, 35-75 yr of age, have been recruited from primary care physician offices at three clinical centers for 2 yr of participation. They were randomly assigned to one of three experimental conditions that vary, in a hierarchical fashion, by level of counseling intensity and resource requirements. The interventions, which are based on social cognitive theory and the transtheoretical model, are designed to alter empirically based psychosocial mediators that are known to be associated with physical activity. The present paper describes the theoretical background of the intervention, the intervention methods, and intervention training and quality control procedures.  相似文献

Objective: To test a cognitive mediation model examining whether cognitive appraisals mediate alcohol consumption effects on condom request and unprotected sex intentions. Design: Female social drinkers (N = 173) participated in an experiment comparing four beverage conditions: control, placebo, target BAL = .04%, and target BAL = .08%. Subjects projected themselves into a hypothetical sexual encounter with a new sex partner. Measures: Appraisals of the situation's sexual potential, impelling and inhibiting cognitions, and behavioral intentions were assessed at several points. Results: Findings support the theoretical model, indicating that alcohol's effects on direct condom request and unprotected sex intentions were mediated through cognitive appraisals. Conclusion: Prevention interventions should include information about alcohol's effects on cognitions that may lead to ineffective condom negotiation and unprotected sex.

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. (PsycINFO Database Record (c) 2010 APA, all rights reserved)  相似文献

For 4 decades, vigorous efforts have been based on the premise that early intervention for children of poverty and, more recently, for children with developmental disabilities can yield significant improvements in cognitive, academic, and social outcomes. The history of these efforts is briefly summarized and a conceptual framework presented to understand the design, research, and policy relevance of these early interventions. This framework, biosocial developmental contextualism, derives from social ecology, developmental systems theory, developmental epidemiology, and developmental neurobiology. This integrative perspective predicts that fragmented, weak efforts in early intervention are not likely to succeed, whereas intensive, high-quality, ecologically pervasive interventions can and do. Relevant evidence is summarized in 6 principles about efficacy of early intervention. The public policy challenge in early intervention is to contain costs by more precisely targeting early interventions to those who most need and benefit from these interventions. The empirical evidence on biobehavioral effects of early experience and early intervention has direct relevance to federal and state policy development and resource allocation.

This randomized clinical trial evaluated an HIV-risk reduction (HIV-RR) intervention based on the information–motivation–behavioral skills model. At baseline, 102 women (M age?=?29 years; 88% African American) completed a survey regarding HIV-related knowledge, risk perceptions, behavioral intentions, and risk behavior. Participants were then assigned to either the HIV-RR intervention or a health-promotion control group. Postintervention and follow-up data indicated that women in the HIV-RR program enhanced their knowledge and strengthened their risk reduction intentions relative to controls. Moreover, HIV-RR women who expressed "imperfect" intentions also increased their condom use, talked more with partners about condom use and HIV testing, and were more likely to have refused unprotected sex.

Two hundred forty-six African American adolescents were randomly assigned to an educational program or an 8-week intervention that combined education with behavior skills training including correct condom use, sexual assertion, refusal, information provision, self-management, problem solving, and risk recognition. Skill-trained participants (a) reduced unprotected intercourse, (b) increased condom-protected intercourse, and (c) displayed increased behavioral skills to a greater extent than participants who received information alone. The patterns of change differed by gender. Risk reduction was maintained 1 year later for skill-trained youths. It was found that 31.1% of youths in the education program who were abstinent at baseline had initiated sexual activity 1 year later, whereas only 11.5% of skills training participants were sexually active. The results indicate that youths who were equipped with information and specific skills lowered their risk to a greater degree, maintained risk reduction changes better, and deferred the onset of sexual activity to a greater extent than youths who received information alone.

A meta-analysis examined the extent to which socio-structural and psycho-cultural characteristics of societies correspond with how much gender and ethnic/racial groups differ on their support of group-based hierarchy. Robustly, women opposed group-based hierarchy more than men did, and members of lower power ethnic/racial groups opposed group-based hierarchy more than members of higher power ethnic/racial groups did. As predicted by social dominance theory, gender differences were larger, more stable, and less variable from sample to sample than differences between ethnic/racial groups. Subordinate gender and ethnic/racial group members disagreed more with dominants in their views of group-based hierarchy in societies that can be considered more liberal and modern (e.g., emphasizing individualism and change from traditions), as well as in societies that enjoyed greater gender equality. The relations between gender and ethnic/racial groups are discussed, and implications are developed for social dominance theory, social role theory, biosocial theory, social identity theory, system justification theory, realistic group conflict theory, and relative deprivation theory.

This study investigated the efficacy of a 10-session, HIV-risk-reduction intervention with 221 women and 187 men receiving outpatient psychiatric care for a mental illness. Patients were randomly assigned to the HIV intervention, a structurally equivalent substance use reduction (SUR) intervention, or standard care; they were assessed pre- and postintervention and at 3- and 6-month follow-ups. Patients receiving the HIV-risk-reduction intervention reported less unprotected sex, fewer casual sex partners, fewer new sexually transmitted infections, more safer sex communications, improved HIV knowledge, more positive condom attitudes, stronger condom use intentions, and improved behavioral skills relative to patients in the SUR and control conditions. Patients receiving the SUR intervention reported fewer total and casual sex partners compared with control patients. Exploratory analyses suggested that female patients and patients diagnosed with a major depressive disorder were more likely to benefit from the HIV-risk-reduction intervention.

Effectiveness of HIV interventions among women drug users   总被引:1,自引:0,他引:1  
A prospective cohort study was conducted among chronic injecting and crack cocaine drug using women. The hypothesis tested was that participation in a standard-plus-innovative intervention was more likely to produce behavior change than participation in a standard intervention. Standardized intervention protocols and corresponding instruments were designed. Data were collected on drug and sex risk behaviors at baseline and six-month follow-up intervals. The level of behavioral change in two intervention arms--standard and a standard-plus-innovative intervention--was measured by composite sex risk and drug risk scores using the generalized estimating equation approach. The results show that on four risk measures the enhanced intervention was significantly associated with positive change in both drug use and sexual behavior: less frequent drug use, less drug use during sex, and more frequent condom use during particular frequencies for specific types of sexual activities. Public health interventions are effective when targeting specific risk behaviors through interventions tailored to prevent HIV and reduce risk behaviors among specific cultural and gender groups.  相似文献

Only one prior study has examined why adolescent smoking cessation interventions are effective. To address this understudied and important issue, we examined whether a large adolescent smoking cessation intervention trial's outcomes were mediated by social cognitive theory processes. In a randomized trial (N = 2,151), counselors proactively delivered a telephone intervention to senior year high school smokers. Mediators and smoking status were self-reported at 12-months postintervention eligibility (88.8% retention). At least 6-months abstinence was the outcome. Among all enrolled smokers, increased self-efficacy to resist smoking in (a) social and (b) stressful situations together statistically mediated 55.6% of the intervention's effect on smoking cessation (p p  相似文献
