RESUMEN

OBJECTIVE: To evaluate the prospective relation between dispositional traits of optimism and pessimism and in vitro fertilization (IVF) treatment failure among women seeking medical intervention for infertility. METHODS: Among 198 women (aged 24-45 years, mean [standard deviation] = 35.1 [4.1] years; white, 77%), the outcome of each participant's first IVF treatment cycle was examined. Treatment outcome was classified as being successful (versus failed) if the woman either delivered a baby or was pregnant because of the cycle by the end of the 18-month study period. At baseline, optimism and pessimism were measured as a single bipolar dimension and as separate unipolar dimensions according to the Life Orientation Test total score and the optimism and pessimism subscale scores, respectively. RESULTS: Optimism/pessimism, measured as a single bipolar dimension, predicted IVF treatment failure initially (B = -0.09, p = .02, odds ratio [OR] = 0.917, 95% confidence interval [CI] = 0.851-0.988), but this association attenuated after statistical control for trait negative affect (B = -0.06, p = .13, OR = 0.938, 95% CI = 0.863-1.020). When examined as separate unipolar dimensions, pessimism (B = 0.14, p = .04, OR = 1.146, 95% CI = 1.008-1.303), not optimism (B = -0.09, p = .12, OR = 0.912, 95% CI = 0.813-1.023), predicted IVF treatment failure independently of risk factors for poor IVF treatment response and trait negative affect. CONCLUSIONS: Being pessimistic may be a risk factor for IVF treatment failure. Future research should attempt to delineate the biological and behavioral mechanisms by which pessimism may negatively affect treatment outcomes.

RESUMEN

OBJECTIVES: A core construct targeted by behavioural interventions is the perception that one is at risk for acquiring a sexually transmitted disease (STD). The objective of this analysis was to examine the role of intimacy on perceptions of risk for an STD (PRSTD) and condom use within late adolescent females' main relationships. METHODS: A clinical sample of African-American women aged 14-19 years at enrolment were followed prospectively for 3 years. At each semiannual interview, participants reported their partner-specific PRSTD, feelings of intimacy, perceptions of partner's concurrency and condom use at last sex for each of their main sex partners. RESULTS: A total of 285 individuals reported 724 main relationships. Using generalised estimating equations, intimacy was negatively associated with risk perception, after adjusting for perceptions of partner concurrency (OR: 0.68; 95% CI 0.60 to 0.76). PRSTD was no longer associated with condom use after adjusting for intimacy (OR: 1.30; 95% CI 0.83 to 2.02. CONCLUSIONS: Intimacy was found to be associated with risk perception and condom use within adolescent main relationships. Adolescents may not view their intimate partners as sources of infection. The success of individual-level STD prevention efforts, such as condom promotion, might be limited as condoms may be in conflict with adolescents' expectations about intimate relationships.

RESUMEN

OBJECTIVES: Early childhood caries (ECC) is very prevalent among young Hispanic children. ECC is amenable to a variety of preventive procedures, yet many Hispanic families underutilize dental services. Acceptability research may assist in health care planning and resource allocation by identifying patient preferences among efficacious treatments with the goal of improving their utilization. The purposes of this study were (a) to develop a culturally competent acceptability assessment instrument, directed toward the caregivers of young Hispanic children, for five preventive dental treatments for ECC and (b) to test the instrument's reliability and validity. METHODS: An instrument of five standard treatments known to prevent ECC was developed, translated, reviewed by focus groups, and pilot tested, then tested for reliability The instrument included illustrated cards, brief video clips, and samples of the treatments and was culturally appropriate for low-income Hispanic caregivers. In addition to determining the acceptability of the five treatments individually, the treatments were also presented as paired comparisons. RESULTS: Focus groups and debriefing interviews following the pilot tests established that the instrument has good face validity. The illustrated cards, product samples, and video demonstrations of the five treatments resulted in an instrument possessing good content validity. The instrument has good to excellent test-retest reliability, with identical time 1-time 2 responses for each of the five treatments 92 percent of the time (range 87 to 97 percent), and the same treatment of the paired comparisons preferred 75 percent of the time (range 61 to 90 percent). CONCLUSIONS: The acceptability instrument described is reliable and valid and may be useful in program planning efforts to identify and increase the utilization of preferred ECC preventive treatments for target populations.

RESUMEN

CONTEXT: Effective STD and pregnancy prevention efforts should benefit from knowledge of what motivates adolescents to have sex. Positive motivations, and how they differ by gender and sexual experience, are poorly understood. METHODS: A sample of 637 ninth graders were asked about their relationship goals, expectations of the degree to which sex would satisfy these goals and sexual experience. Three scales measured adolescents' goals for intimacy, sexual pleasure and social status within a romantic relationship. Another three scales measured expectations that sex would lead to these goals. Data were examined in analyses of variance and mixed models. RESULTS: Participants valued intimacy the most, then social status and, finally, sexual pleasure. These relationship goals differed significantly by gender and sexual experience. Females valued intimacy significantly more and sexual pleasure less than males. Sexually experienced adolescents valued both intimacy and pleasure more than sexually inexperienced adolescents. Among females, but not males, sexually experienced adolescents valued the goal of social status less than those with no sexual experience did. Adolescents expected that sex would most likely lead to sexual pleasure, then intimacy and, finally, social status. Females and sexually inexperienced adolescents reported lower expectations that sex would meet goals than did males and sexually experienced participants. CONCLUSIONS: Adolescents view intimacy, sexual pleasure and social status as important goals in a relationship. Many have strong positive expectations that sex would satisfy these goals. Prevention programs and providers should address the risks of sex in the context of expected benefits.

RESUMEN

BACKGROUND: African American female adolescents living in low-income urban areas are at increased risk for sexually transmitted diseases. OBJECTIVE: To determine if high levels of perceived parental supervision and communication were associated with reduced gonorrhea (GC) and chlamydia (CT) incidence in low-income, African American, sexually experienced female adolescents, aged 14 to 19 years, attending urban health clinics. DESIGN: A prospective cohort study was used to determine the predictive value for high levels of parental supervision and communication on GC and CT infection in 158 adolescent females. Multiple logistic regression analysis explored the association between incident infection and perceived parental supervision and perceived parental communication while controlling for relevant demographic and behavioral factors (age, religious involvement, school enrollment, a 2-parent household, having a main sex partner, and having concurrent sex partners). RESULTS: When adjusted for age and baseline GC and CT infection, high levels of perceived parental supervision were associated with reduced GC and CT incidence (adjusted odds ratio, 0.06; 95% confidence interval, 0.01-0.31). High levels of perceived parental communication were not associated with reduced GC and CT incidence (adjusted odds ratio, 0.55; 95% confidence interval, 0.21-1.42). CONCLUSIONS: The link between parental supervision and disease acquisition is particularly valuable because it provides evidence that parental supervision can result in lower sexually transmitted disease rates in urban high-prevalence populations. This is important for interventions designed to increase parental involvement as a strategy for promoting protective sexual behaviors in female adolescents because it indicates that increased parental involvement can also influence subsequent disease acquisition.

RESUMEN

BACKGROUND: Primary alcohol abuse-prevention services delivered to adolescents are inadequate, despite the fact that alcohol abuse is a major health problem. Physicians' attitudes and beliefs regarding primary prevention of adolescent alcohol abuse and appropriate onset ages of alcohol use may be useful in understanding why delivery of prevention services is inadequate, but as yet has not been investigated. OBJECTIVES: To examine (1) physicians' attitudes and beliefs regarding alcohol abuse prevention and practice, and (2) correlates of these attitudes and beliefs, including the delivery of primary alcohol abuse-prevention services to adolescents. METHODS: A national, stratified random sample of pediatricians and family practitioners was drawn from the American Medical Association's Masterfile Registry. Inclusion criteria included active medical practice and seeing at least one adolescent per week. The response rate was 63%, resulting in a final sample of 1842 physicians. Participants were queried about their practice, alcohol use, attitudes and beliefs, and delivery of alcohol-related screening and education to adolescents. RESULTS: On average, physicians reported providing alcohol-related screening to 40.3% (standard error [SE]=0.6) and education to 52.0% (SE=0.8) of their adolescent patients. Participants had positive attitudes toward adolescents, believed that prevention was important, and approved of alcohol screening early in adolescence, but did not feel very comfortable about their adolescent alcohol-management skills. Except for ceremonial use, most physicians did not believe in underage drinking. Attitudes and beliefs were significantly related to the delivery of alcohol screening (R(2)=0.34, p < 0.001) and education (R(2)=0.18, p < 0.001). Participants who delivered more screening and education had more positive beliefs in the importance of prevention (beta=0.14 and beta=0.13, respectively; p < 0.001); approved of early alcohol screening (beta=0.29 and beta=0.09, respectively; p < 0.001); and were more comfortable with their alcohol management skills (beta=0.31 and beta=0.28, respectively; p < 0.001). A profile of physicians with positive attitudes and beliefs is presented. CONCLUSIONS: Physician attitudes and beliefs are associated with variations in alcohol screening and education services delivered to adolescents. A better understanding of physicians' attitudes and beliefs can be useful in providing physician education and training aimed at improving primary alcohol-abuse prevention.

RESUMEN

Some investigators propose that adolescents engage in risky behaviors mainly because they perceive themselves to be invulnerable to risk. However, studies have typically not included perceived benefits. In the current study, 5th, 7th, and 9th graders were surveyed about their perceptions of and experience with alcohol and tobacco. Results indicated that perceptions of the benefits were significantly related to drinking and smoking 6 months later, over and above perceptions of the risks, age of the respondent, and experience level. Further, the importance of benefits was replicated across 3 separate analyses. Experience with alcohol alone, especially positive experience, was also related to perception and behavior. These findings are discussed in terms of how to improve messages and influence adolescents' decisions regarding risk-taking behaviors.

RESUMEN

CONTEXT: Understanding young adults' perceived risk of chlamydial and gonococcal infection can inform interventions to reduce the prevalence of these sexually transmitted diseases. METHODS: Bivariate and multivariate analyses, using data from Wave 3 of the National Longitudinal Study of Adolescent Health (2001-2002), were conducted to examine relationships between perceived risk and selected characteristics in two groups: a nationally representative sample of sexually experienced 18-26-year-olds and a subsample of those who tested positive for chlamydia or gonorrhea. The relationship between current infection and perceived risk was also evaluated. RESULTS: Only 14% of all respondents and 33% of infected participants reported some perceived risk of chlamydial or gonococcal infection. In the overall sample, the odds of perceiving risk were significantly elevated among blacks, Hispanics, unmarried respondents, inconsistent condom users and nonusers, respondents who reported multiple partners in the past year, those who had received a diagnosis of chlamydia or gonorrhea in the past year, and those reporting current symptoms (odds ratios, 1.5-3.3). Currently infected participants were significantly more likely than those who were not infected to perceive some risk of infection (2.4). Among infected respondents, the factors positively associated with perceived risk were being black or Hispanic, using condoms inconsistently or not using them, having exchanged money for sex, having been tested in the past year but with no diagnosis, having received a diagnosis, and reporting current symptoms (2.5-5.2). CONCLUSIONS: Interventions to increase the accuracy of young adults' risk perceptions may influence sexual and health care-seeking behaviors in a way that will reduce rates of chlamydia and gonorrhea.

RESUMEN

CONTEXT: Adolescents' dual use of condoms and hormonal contraceptives is low, and the motivations underlying their decisions to combine contraceptives are not understood. METHODS: To examine how pregnancy concerns, sexually transmitted disease (STD) concerns and type of sexual partner influence contraceptive use, we recruited 436 sexually experienced adolescents from two clinics. In structured interviews, we asked adolescents to describe their recent partners, their method use, and their pregnancy and STD concerns. Data were analyzed using logistic regression. RESULTS: The odds that adolescents used condoms with main partners were significantly lower among those who used hormonal contraceptives than among nonusers of these methods (odds ratios, 0.4 for young women and 0.3 for young men). With casual partners, no association existed between adolescents' condom and hormonal contraceptive use. Concerns about pregnancy and STDs influenced this association for women with main partners. Among young women who perceived pregnancy as more negative, hormonal contraceptive users had reduced odds of using condoms (0.1). No association existed between use of the two methods among young women whose view of pregnancy was less negative. Young women who perceived themselves to be less at risk of acquiring an STD had reduced odds of using condoms if they were using hormonal contraceptives (0.2). Among young women who perceived themselves to be more at risk of acquiring an STD, no association existed. CONCLUSIONS: Adolescents trade off between hormonal contraceptives and condoms according to partner type and perceived risks. Adolescents' dual-method use may improve if providers tailor counseling to adolescents' perceived risk of STDs and pregnancy, and if they address prevention of both as a related decision.

RESUMEN

Psychologists have an opportunity to offer their expertise at a time when health care settings are beginning to recognize the importance of behaviorally based interventions for improving health and health care. The authors review the changing patterns of health and illness that have led to an increased interest in the role of patient and provider behavior and discuss the many advantages of using health care settings as prevention sites. Examples of successful behaviorally based prevention programs are presented, along with the evidence supporting the cost-effectiveness of such programs. Challenges presented by working in health care settings are described. Throughout, the authors emphasize the multiple opportunities for psychologists' involvement across a wide variety of health care delivery sites.

RESUMEN

Adolescents assessed after the September 11, 2001 terrorist attacks perceived the risk of dying from general causes, a tornado, and an earthquake as dramatically higher than did adolescents assessed years before the attacks. Adolescents' heightened perceptions of vulnerability to death extended beyond the terrorist acts, and generalized to unrelated risks.

RESUMEN

PURPOSE: To examine how the relative power of adolescent sexual partners in the domain of emotional intimacy is related to condom use. METHODS: Interviewed 228 adolescents who visited an STD clinic in San Francisco. Adolescents were aged 14-19 years, 69% were female, and they were ethnically diverse. We developed a measure of relative power in the domain of emotional intimacy, by adapting five items from existing measures and developing three items ourselves. The partner who had less desire for emotional intimacy was considered to have more power in that domain. We also measured relative decision-making power. Data were analyzed using logistic regression and Student's t-tests. RESULTS: Adolescents who had more power than their partners in the domain of emotional intimacy were more likely to get their way about condom use than adolescents who had less power in this domain. Decision-making power was not related to whether adolescents got their way about condom use. Young men reported greater emotional intimacy power and greater decision-making power than young women. However, gender was not related to getting one's way about condom use. CONCLUSIONS: The results suggest the importance of assessing relative power in the sexual relationships of adolescents when predicting condom use.

RESUMEN

The purpose of this paper was to elicit attitudes, beliefs, and feelings about testing for curable STDs outside of clinic settings. Telephone interviews were conducted with 120 black, Latino, and white young adults aged 18 to 25 years. Data were analyzed with descriptive frequencies and content analyses. Most (73%) reported people their age would use self-test urine STD kits if available. Perceived advantages were privacy and convenience. Disadvantages included not having an immediate "face-to-face" discussion with a medical professional about positive tests. Young adults report a range of attitudes, beliefs, and feelings that may influence the success of efforts to screen for curable STDs in nonclinic settings.

RESUMEN

OBJECTIVE: To examine whether psychological distress predicts IVF treatment outcome as well as whether IVF treatment outcome predicts subsequent psychological distress. DESIGN: Prospective cohort study over an 18-month period. SETTING: Five community and academic fertility practices. PATIENT(S): Two hundred two women who initiated their first IVF cycle. INTERVENTION(S): Women completed interviews and questionnaires at baseline and at 4, 10, and 18 months' follow-up. MAIN OUTCOME MEASURE(S): IVF cycle outcome and psychological distress. RESULT(S): In a binary logistic model including covariates (woman's age, ethnicity, income, education, parity, duration of infertility, and time interval), pretreatment depression and anxiety were not significant predictors of the outcome of the first IVF cycle. In linear regression models including covariates (woman's age, income, education, parity, duration of infertility, assessment point, time since last treatment cycle, and pre-IVF depression or anxiety), experiencing failed IVF was associated with higher post-IVF depression and anxiety. CONCLUSION(S): IVF failure predicts subsequent psychological distress, but pre-IVF psychological distress does not predict IVF failure. Instead of focusing efforts on psychological interventions specifically aimed at improving the chance of pregnancy, these findings suggest that attention be paid to helping patients prepare for and cope with treatment and treatment failure.

RESUMEN

PURPOSE: National surveys have found that the percentage of female adolescents who report condom use at last sex differs by age group. Using longitudinal data, the authors examined whether there are longitudinal changes in condom use and whether these changes are due in part to developmental changes in the types of sexual relationships in which young women are involved. METHOD: A clinic sample of 298 African American female adolescents aged 14-19 years at enrollment were interviewed every 6 months for a period of 36 months. At each interview, participants were asked to name all their recent sex partners, to classify each partner as main or casual, and to report whether a condom was used at last sex with each of these partners. Hierarchical generalized linear modeling was used to analyze repeated measures within individuals. RESULTS: On average, there was no statistically significant change in condom use over time. The odds of having a single main partner increased by 4% for each 6 months spent in the study (odds ratio: 1.04%, 95% confidence interval: 1.02-1.05). Stratifying females by longitudinal relationship patterns resulted in three distinct condom use trajectories. CONCLUSION: Data suggest that longitudinal changes in condom use are a function of developmental changes in relationships, whereby young women trend toward monogamous relationships. As condoms are abandoned within these monogamous relationships, lowering infection rates in sex partners through broader sexually transmitted infections screening or through community-level interventions aimed at sex networks might prove to be a more effective approach to reduce sexually transmitted infections risk in young women.

RESUMEN

OBJECTIVE: To determine the relationship between number of fertility treatment cycles and pregnancy rates. DESIGN: Prospective cohort study. SETTING: Eight community and academic infertility practices. PATIENT(S): Four hundred eight (408) couples presenting for an infertility evaluation. INTERVENTION(S): Face-to-face and telephone interviews and questionnaires. MAIN OUTCOME MEASURE(S): Incidence of pregnancy. Cox regression analysis compared the efficacy of cycle-based fertility treatments with no cycle-based fertility treatment after multivariable adjustment. RESULT(S): Couples using one to two medications-only cycles had a significantly higher pregnancy rate (hazard ratio [HR] 4.7 [95% confidence interval 1.3-16.6]), a benefit that did not persist after three or more cycles (HR 0.6 [0.1-3.2]). Couples using IUI for one (HR 2.9 [1.4-5.8]), two (HR 2.0 [0.9-4.5]), and three cycles (HR 4.5 [1.8-10.9]) were more likely to achieve a pregnancy. No additional benefit was seen for couples using four or more IUI cycles (HR 1.0 [0.4-2.6]). In vitro fertilization was associated with significant benefit for couples using one (HR 2.8 [1.5-5.2]) and two cycles (HR 2.2 [1.2-4.1]). Couples using three or more IVF cycles had a non-statistically significant higher likelihood of pregnancy (HR 1.3 [0.7-2.4]). CONCLUSION(S): Cycle-based fertility treatments may offer a point of diminishing returns for infertile couples: two cycles of medications only, three cycles of IUI, and two cycles of IVF.

RESUMEN

OBJECTIVE: To determine the effect of income, education, and race on the use and outcomes of infertility care. DESIGN: Prospective cohort. SETTING: Eight community and academic infertility practices. PATIENT(S): Three hundred ninety-one women presenting for an infertility evaluation. INTERVENTION(S): Face-to-face and telephone interviews and questionnaires. MAIN OUTCOME MEASURE(S): Use of infertility services and odds of pregnancy. Linear and logistic regression used to assess relationship between racial and socioeconomic characteristics, use of infertility services, and infertility outcomes. RESULT(S): After adjustment for age and demographic and fertility characteristics, college-educated couples (ß = $5,786) and households earning $100,000-$150,000 (ß = $6,465) and ≥$150,000 (ß = $8,602) spent significantly more on infertility care than their non-college-educated, lower-income counterparts. Higher income and college-educated couples were much more likely to use more cycles of higher-intensity fertility treatment. The increased cost of infertility care was primarily explained by these differences in number and type of infertility treatment. Even after adjustment for these factors and total amount spent on fertility care, having a college degree was associated with persistently higher odds of achieving a pregnancy (OR = 1.9). CONCLUSION(S): Education and household income were independently associated with the amount of money spent on fertility care. This relationship was primarily explained by types and intensity of infertility treatments used. Having at least a college degree was independently associated with improved odds of pregnancy.

RESUMEN

PURPOSE: To determine whether the delivery of preventive services changes adolescent behavior. This exploratory study examined the trajectory of risk behavior among adolescents receiving care in three pediatric clinics, in which a preventive services intervention was delivered during well visits. METHODS: The intervention consisted of screening and brief counseling from a provider, followed by a health educator visit. At age 14 (year 1), 904 adolescents had a risk assessment and intervention, followed by a risk assessment 1 year later at age 15 (year 2). Outcomes were changes in adolescent behavior related to seat belt and helmet use; tobacco, alcohol, and drug use; and sexual behavior. Analysis involved age-related comparisons between the intervention and several cross-sectional comparison samples from the age of 14-15 years. RESULTS: The change in helmet use in the intervention sample was 100% higher (p < .05), and the change in seat belt use among males was 50% higher (p = .14); the change in smoking among males was 54% lower (p < .10), in alcohol use was no different, and in drug use was 10% higher (not significant [NS]); and the change in rate of sexual intercourse was 18% and 22% lower than cohort comparison samples (NS). CONCLUSIONS: The intervention had the strongest effect in the area of helmet use, shows promise for increasing seat belt use and reducing smoking among male adolescents, and indicates a nonsignificant trend toward delaying the onset of sexual activity. Participation in the intervention seemed to have no effect on the rates of experimentation with alcohol and drugs between the ages of 14 and 15 years.

RESUMEN

OBJECTIVE: To examine resource use (costs) by women presenting for infertility evaluation and treatment over 18 months, regardless of treatment pursued. DESIGN: Prospective cohort study in which women were followed for 18 months. SETTING: Eight infertility practices. PATIENT(S): Three hundred ninety-eight women recruited from infertility practices. INTERVENTION(S): Women completed interviews and questionnaires at baseline and after 4, 10, and 18 months of follow-up. Medical records were abstracted after 18 months to obtain details of services used. MAIN OUTCOME MEASURE(S): Per-person and per-successful-outcome costs. RESULT(S): Treatment groups were defined as highest intensity treatment use. Twenty percent of women did not pursue cycle-based treatment; approximately half pursued IVF. Median per-person costs ranged from $1,182 for medications only to $24,373 and $38,015 for IVF and IVF-donor egg groups, respectively. Estimates of costs of successful outcomes (delivery or ongoing pregnancy by 18 months) were higher--$61,377 for IVF, for example--reflecting treatment success rates. Within the time frame of the study, costs were not significantly different for women whose outcomes were successful and women whose outcomes were not. CONCLUSION(S): Although individual patient costs vary, these cost estimates developed from actual patient treatment experiences may provide patients with realistic estimates to consider when initiating infertility treatment.

RESUMEN

OBJECTIVE: To determine the views toward donor sperm and eggs of both men and women. The use of donor sperm or ova becomes an option for some infertile couples. DESIGN: Prospective cohort of infertile couples. SETTING: Eight California reproductive endocrinology practices. PATIENT(S): Infertile couples (n=377) were recruited after an initial infertility clinic visit. MAIN OUTCOME MEASURE(S): From questionnaires administered at recruitment, ratings concerning the impact of the use of donor gametes were assessed. Differences between men and women in attitudes toward donor gametes were compared with analysis of variance (ANOVA). Linear regression was used to identify independent predictors of attitudes toward gametes. RESULT(S): Women's attitudes toward donor sperm were significantly more negative than their attitudes toward donor eggs (5.1+/-1.4 vs. 4.7+/-1.6). Similarly, male donor gamete attitude scores were higher for donor sperm compared with donor eggs (4.9+/-1.6 vs. 4.1+/-1.6). Both men and women agreed that the use of donor sperm was more likely to have negative effects on their relationship and negative societal ramifications. Female donor gamete attitude scores were predicted by marital status, race, and education, whereas men's scores were independent of all measured factors. CONCLUSION(S): Both men and women view the use of donor sperm with more skepticism compared with the use of donor eggs, suggesting a unique underlying perception regarding the use of male donor gametes.
