BEHAVIORAL RESEARCH IN SEXUALLY TRANSMITTED DISEASES NIH GUIDE, Volume 22, Number 32, September 3, 1993 PA NUMBER: PA-93-108 P.T. 34 Keywords: Behavioral/Social Studies/Service Sexually Transmitted Diseases Disease Prevention+ National Institute of Allergy and Infectious Diseases National Institute of Child Health and Human Development National Institute on Aging PURPOSE The National Institute of Allergy and Infectious Diseases (NIAID), the National Institute of Child Health and Human Development (NICHD), and the National Institute on Aging (NIA) invite applications for intervention-oriented behavioral research on sexually transmitted diseases (STDs). The prevention and control of STDs relies on several strategies: blocking transmission, seeking early diagnosis and treatment, utilizing available vaccines, and altering risk-associated behaviors over the life course. Each strategy has a behavioral component that is critical to the success of STD prevention and control. Behavioral research to reduce the incidence, prevalence, and severity of STDs should include multidisciplinary efforts that incorporate the measurement of microbiologic and/or disease outcomes as well as behavioral outcomes. HEALTHY PEOPLE 2000 The Public Health Service (PHS) is committed to achieving the health promotion and disease prevention objectives of "Healthy People 2000," a PHS-led national activity for setting priority areas. This program announcement, Behavioral Research in Sexually Transmitted Diseases, is related to the priority area of sexually transmitted diseases. Potential applicants may obtain a copy of "Healthy People 2000" (Full Report: Stock No. 017-001-00474-0) or "Healthy People 2000" (Summary Report: Stock No. 017-001-10473-1) through the Superintendent of Documents, Government Printing Office, Washington, DC 20402-9325 (telephone 202-783-3238). ELIGIBILITY REQUIREMENTS Applications may be submitted by domestic and foreign, non-profit and for-profit research institutions; public and private organizations such as universities, colleges, hospitals, laboratories, units of State and local governments, and eligible agencies of the Federal government. Applications from minority and female investigators are encouraged. Foreign institutions are not eligible for the First Independent Research Support and Transition (FIRST) award (R29). MECHANISM OF SUPPORT This program announcement will use the National Institutes of Health (NIH) investigator-initiated research project grant (R01) and the FIRST Award (R29). Responsibility for the planning, direction, and execution of the proposed project will be solely that of the applicant. The maximum duration of support for a given project period is five years. Investigators interested in collaborative and interactive research efforts around the central theme of behavioral research for the prevention and control of STDs may consider submission of interactive research project grants (IRPGs). Such investigators should first contact NIH program staff listed under INQUIRIES for advice on this mechanism and the method of application. RESEARCH OBJECTIVES Background In November 1989 and April 1990, the NIAID convened two interdisciplinary conferences on integrated behavioral research for the prevention and control of STDs to develop an intervention-oriented behavioral research agenda. The reports of these conferences are found in Appendix 1 of Research Issues in Human Behavior and Sexually Transmitted Diseases in the AIDS Era, Washington, DC: American Society for Microbiology, 1991, available from the publisher. The research objectives of this program announcement are based on the recommendations of those conferences. Magnitude and Impact of STDs Despite control efforts to prevent the spread of STDs, including human immunodeficiency virus (HIV) infection, both bacterial and viral STDs remain epidemic in many areas of the United States. Current estimates predict that there will be 10 to 13 million new cases of STDs this year, not including HIV infection. Associated costs are likely to exceed $5 billion. Complications of STDs include infertility, ectopic pregnancy, anogenital cancer, fetal wastage, low birth weight, and congenital/perinatal infection. Furthermore, recent studies indicate that ulcerative diseases as well as the more prevalent non-ulcerative STDs increase the risk of HIV transmission at least three- to five-fold. The long-term sequelae of STDs cause significant morbidity and mortality, and women and their infected infants bear much of the associated disease burden. Additionally, STDs disproportionately affect the health of several minority populations and a significant proportion of adolescents in the United States. Both the incidence of STDs and their long-term, potentially fatal sequelae are consistently higher among black and Hispanic Americans than among white Americans. Over 60 percent of all STD cases occur in people less than 25 years of age, and 3 million teenagers are infected with an STD each year. Transmission Dynamics The persistence, spread, and progression of STDs are related not only to biological factors but also to behavioral and social factors. According to May and Anderson's model on transmission dynamics, the reproductive rate of infection or the average number of sexually transmitted infections generated by an infected person is a function of (1) transmission probability, (2 contact rates, and (3) duration of infectiousness. In addition to biological factors, transmission probability is affected by the type and frequency of sexual behavior and the extent to which each behavior facilitates transmission. Contact rates are a function of the absolute number of partners as well as the characteristics of sexual partners encountered over a specified period of time. Duration of infectiousness, or the period of time during which an individual remains infectious, is determined by recognition of symptoms or risk and health-seeking behaviors, which lead to diagnosis and treatment. Behavioral interventions to prevent the acquisition, spread, and progression of STDs are associated with all three elements of May and Anderson's model. Decreasing transmission probability requires changing individuals' behaviors, including decreasing or eliminating sexual behaviors known to facilitate STD transmission and increasing condom use behavior. Decreasing contact rates calls for reduction in the number of sexual partners. Decreasing the period of infectiousness can be accomplished through symptom recognition, risk awareness, and increased health-seeking behavior as well as use of effective vaccines. STD Prevention and Control Strategies The ultimate outcome of behavioral research activities will be the design, implementation, and evaluation of interventions to decrease behaviors associated with STD risk and to increase health-seeking behaviors. The sequential research steps needed to build effective interventions are: 1. basic research to define antecedents associated with specific behaviors (including beliefs, perceptions, and motivations); 2. development of hypotheses derived from basic research concerning new approaches to STD prevention, treatment, and control; 3. pilot tests of intervention components on small, well defined samples; 4. experimental or quasi-experimental tests of complete interventions (formed from several components evaluated in pilot tests) to detect behavioral and microbiological effects. It should be noted that some of the behavioral research that has been conducted for HIV/AIDS prevention may augment or accelerate basic research or hypothesis development related to other STDs. For example, frequency of unprotected intercourse, number of sexual partners, and asymptomatic infection similarly affect the transmission dynamics of all STDs, including HIV infection. However, antecedents of preventive action may differ for STDs that are fatal (e.g., HIV infection), compared to those that incur long term consequences (e.g., pelvic inflammatory disease or genital herpes), or those that present only as an acute disease without long term sequelae (e.g., treatable bacterial STDs). Moreover, the factors that affect duration of infectiousness are different for HIV and many STDs. Infectiousness may be limited by curative therapy for bacterial STDs, and there is an available vaccine for one viral STD (hepatitis B). While the scientific areas covered in the following research objectives are very broad, it is not expected that any single application will cover the range of scientific areas described below. Applicants are encouraged to focus their investigations. A. Decrease Transmission Probability and Contact Rates The goal of research to decrease transmission probability and contact rates is to reduce risk of exposure to and acquisition of STDs through: (1) postponing coital debut; (2) reducing frequency of sexual practices associated with higher rates of transmission; (3) reducing numbers of sexual partners; and (4) increasing use of barrier contraceptives (e.g., condoms). While other NIH programs support research on these behaviors for HIV prevention (see addendum section), research targeted by this program announcement focuses on the reduction of the incidence, prevalence, and severity of STDs other than HIV and should include microbiologic and/or disease outcomes as well as behavioral outcomes. 1. Individual Factors: To change behaviors that put people at risk for STDs or their sequelae, individuals must recognize that there is a problem in their environment that is both serious and personally relevant; be motivated to act; and have the relevant knowledge, skills, and tools to undertake recommended action. Specific areas for research include, but are not limited to: o identification of antecedents and determinants of behaviors relevant to STD risk reduction in different populations (i.e., does the threat of PID and its sequelae motivate women to take preventive action against STDs); o ascertainment of optimal content, format, and venues for delivering information about acquisition and transmission of STDs and the serious consequences associated with these infections (i.e., what misperceptions about STDs are related to sexual risk taking, how is information concerning STDs conveyed through formal and informal networks of communication, and how can these networks be used to deliver programs that will result in a decrease in incident disease); o identification of skills needed to prevent STD transmission and optimal mechanisms to impart those skills (i.e., what is the best way to increase consistent condom use among individuals with genital herpes who may be asymptomatic but shedding virus). 2. Environmental Factors: In addition, impediments in the social environment must be identified and removed or diminished if individual behavioral change to reduce risk of STDs is to be initiated and sustained. Thus, research may focus on the individual as the target of the intervention or larger social structures. Specific areas of STD-related research on environmental factors may include: o determination of key norms that govern behaviors associated with STD transmission and development of strategies to modify them (i.e., what are the norms governing sexual intercourse during treatment for a bacterial STD, how do they vary by subpopulation, and what intervention strategies would be effective to modify them); o increase the adoption and diffusion of new and existing technologies to prevent STDs, such as barrier methods, that are compatible with human skills, dispositions, and perceptions related to STDs, including those technologies that can be controlled exclusively by women (i.e., what characteristics of vaginal suppositories enhance or discourage use among women, and which should be considered in the development of new topical microbicides to prevent STDs). On the basis of the findings of this research, STD interventions that target either individuals, groups, or the social environment will then be designed, implemented, and evaluated. B. Decrease the Duration of Infectiousness The goal of research in this area is to decrease the infectious period through increasing health-seeking behaviors leading to early diagnosis and treatment of STDs. 1. Diagnosis and Treatment: Behavioral research is needed to increase appropriate use of diagnostic tests. Given the high prevalence of asymptomatic disease, effective strategies should encourage individuals to seek STD screening on the basis of recognition of risk-related behavior rather than symptoms, which may not be present or recognized. For treatment to be effective, the patient must comply with the prescribed regimen. Optimal treatment for STDs includes taking medication, abstaining from sex during treatment (i.e., until the infection is no longer transmissible), referring partners for screening, and returning for follow-up screening or care after treatment, as necessary. Examples of research areas of interest include, but are not limited to, the following, and all should include both behavioral and microbiologic outcomes: o identification of antecedents and determinants of health-seeking behaviors that lead to STD diagnostic screening and medication compliance; o determination of level of current knowledge about benefits associated with screening, early treatment and medication compliance, and identification of misperceptions and other barriers to use; determination of optimal content, format, and venues for information delivery about screening and treatment; o development of behavioral instruments accompanied by microbiologic or disease measures that can (1) identify women at risk for repeat infection, (2) distinguish women with infection limited to the lower genital tract from those at risk for progression to upper genital tract infection, and (3) distinguish women with upper tract infection from those at risk for chronic sequelae; o determination of characteristics of health care provider-patient interaction that support and sustain diagnostic screening and compliance with treatment; o identification of barriers (from the perspective of both the patient and the health care provider) to appropriate use of screening and treatment; and o ascertainment of the impact of product characteristics (e.g., programmed timers to prompt pill taking) on medication compliance. 2. Vaccination: It is likely that vaccines for several STDs will be available by the end of this decade. To make full use of these powerful tools there is a critical need to dissect and understand the behavioral aspect of vaccine acceptance and compliance. Poor acceptance of the hepatitis B vaccine underscores this need. Immunization for hepatitis B has been available since 1982, yet the overall impact on incidence has been negligible. Rates of infection remain high even among high risk groups (i.e., homosexual men). Lack of use and poor compliance with the hepatitis B vaccine regimen underscore the need for research on the complex processes by which an individual arrives at a decision to either accept or decline immunization. This information will be essential in the development of clinical trial protocols and will be critical in increasing the likelihood of use of approved STD vaccines. Examples of research areas of interest include, but are not limited to: o identification of antecedents, determinants, and motivators of vaccine acceptance and compliance; o measurement of current knowledge about benefits associated with STD vaccine acceptance and identification of misperceptions and other barriers to use; o determination of optimal content, format, and venues for information delivery about vaccine availability; and o determination of characteristics of patient-provider interaction that support and sustain vaccine acceptance and compliance. Research to decrease the duration of infectiousness should produce detailed and specific information concerning increased use of diagnosis as well as acceptance of and compliance with treatment and vaccination. These findings will point to elements of interventions that are appropriate for pilot testing. Promising elements can then be folded into more complete interventions, which will be implemented and evaluated in experimental trials. Study Design Considerations In requiring investigators to measure both behavioral and disease or microbiologic outcomes, investigators will need to establish linkages to clinical settings where diagnostic capabilities are present. Treatment becomes an issue (1) if signs or symptoms make disease apparent, or (2) if infection is detected upon screening. In either case, consideration must be given to providing treatment. In addition, intervention research that results in significant benefit to cases should make provisions to provide a similar program to subjects who served as controls. However, other appropriate research designs may go beyond the clinical setting. For example, investigators may wish to consider epidemiologic research or add a component to an ongoing epidemiologic study (i.e., piggybacking an STD component on an existing survey that includes the collection of biologic samples). Epidemiologic research that expands beyond traditional demographic factors to include STD-related behaviors and infection status is integral and complementary to intervention-oriented research. Traditionally, epidemiologic surveys have focused on demographic and ecologic risk factors, such as age, race, sex, and population density. While these may be important indices of risk, they are not amenable to change. It is equally important that epidemiologic research monitor behaviors that may have a demonstrated relationship to STDs and are theoretically changeable. In this way, epidemiologic findings will identify which behaviors are important to consider in constructing pilot programs. Additional areas for research include, but are not limited to: o epidemiologic studies focused on factors associated with transmission probability and contact rates such as age of coital debut, number of partners, as well as factors influencing selection of partners from high risk populations; and o epidemiologic studies to identify sexual and other behaviors that increase risk of transmission or disease progression (e.g., douching or dry sex). Within the context of the research objectives of this program announcement, submission of applications that focus on methodologic research to improve data collected on sexual behaviors, creating valid and reliable indices of important outcome variables, and to probe factors that affect the quality of these data are encouraged. Clinical Assessment and Study Population As stated earlier, applicants are required to assess change in relevant behaviors and status of infection. Therefore, proposed projects must have ties to clinical facilities to characterize subjects with respect to sexually transmitted pathogens including, but not limited to, Chlamydia trachomatis, Neisseria gonorrhoeae, Treponema pallidum, human papillomavirus (HPV), herpes simplex virus type 2 (HSV-2), and human immunodeficiency virus (HIV). Although populations at risk for STDs are also at risk for HIV, studies that focus exclusively on HIV are not included under this program announcement. Certain populations continue to be at greater risk of STD acquisition, transmission, and progression, and they share a disproportionate burden of related disease; applicants are encouraged to investigate research questions in ethnic, racial, gender, and age groups as well as social environments in which risk is greatest. Special emphasis is placed on inner-city minorities, women, and adolescents. STUDY POPULATIONS SPECIAL INSTRUCTIONS TO APPLICANTS REGARDING IMPLEMENTATION OF NIH POLICIES CONCERNING INCLUSION OF WOMEN AND MINORITIES IN CLINICAL RESEARCH STUDY POPULATIONS NIH policy is that applicants for NIH clinical research grants and cooperative agreements are required to include minorities and women in study populations so that research findings can be of benefit to all persons at risk of the disease, disorder or condition under study; special emphasis must be placed on the need for inclusion of minorities and women in studies of diseases, disorders and conditions which disproportionately affect them. This policy is intended to apply to males and females of all ages. If women or minorities are excluded or inadequately represented in clinical research, particularly in proposed population-based studies, a clear compelling rationale must be provided. The composition of the proposed study population must be described in terms of gender and racial/ethnic group. In addition, gender and racial/ethnic issues must be addressed in developing a research design and sample size appropriate for the scientific objectives of the study. This information must be included in the form PHS 398 under Research Plan items 1-4 and item 5-Human Subjects. Applicants are urged to assess carefully the feasibility of including the broadest possible representation of minority groups. However, NIH recognizes that it may not be feasible or appropriate in all research projects to include representation of the full array of United States racial/ethnic minority populations [i.e., Native Americans (including American Indians or Alaskan Natives), Asian and Pacific Islanders, Blacks, Hispanics]. The rationale for studies on single minority population groups should be provided. For the purpose of this policy, clinical research is defined as human biomedical and behavioral studies of etiology, epidemiology, prevention (and preventive strategies), diagnosis, or treatment of diseases, disorders or conditions, including but not limited to clinical trials. The usual NIH policies concerning research on human subjects also apply. Basic research or clinical studies in which human tissues cannot be identified or linked to individuals are excluded. However, every effort should be made to include human tissues from women and racial/ethnic minorities when it is important to apply the results of the study broadly, and this should be addressed by applicants. For foreign awards, the policy on inclusion of women applies fully; since the definition of minority differs in other countries, the applicants must discuss the relevance of research involving foreign population groups to the United States' populations, including minorities. If the required information is not contained within the application, the application will be returned. Peer reviewers will address specifically whether the research plan in the application conforms to these policies. If the representation of women or minorities in a study design is inadequate to answer the scientific question(s) addressed AND the justification for the selected study population is inadequate, it will be considered a scientific weakness or deficiency in the study design and will be reflected in assigning the priority score to the application. All applications for clinical research submitted to NIH are required to address these policies. NIH funding components will not award grants that do not comply with these policies. APPLICATION PROCEDURES Applications are to be submitted on the grant application form PHS 398 (rev. 9/91) and will be accepted on the standard application deadlines for investigator-initiated applications: February 1, June 1, and October 1.

ADDENDUM The National Institute of Mental Health (NIMH) Office of AIDS Programs supports research to better understand, assess, and treat the neuropsychiatric, behavioral, and psychosocial aspects of HIV infection and AIDS. Preventing or changing high risk behaviors and maintaining low risk behaviors are the only available strategies to prevent the further spread of HIV infection. The NIMH supports both preintervention and intervention studies in its behavioral and psychosocial program which includes identification of determinants of high-risk sexual and drug-using behaviors; determinants of maintaining low-risk behaviors, especially for hard-to-reach and special populations; the social contexts in which risk-taking behaviors occur; the impact of affective states (e.g., depression, anxiety, social isolation) on risk behavior; the affects of cognitive impairment on adherence to risk-reduction guidelines; the design, testing, and evaluation of theory-driven behavioral interventions designed to prevent and reduce high-risk behaviors for HIV infection and maintain low-risk behaviors in children, adolescents, and adults; research on interventions targeted to populations for which current research data are not available; the promotion of help-seeking behaviors such as counseling, social support, and early intervention services; adherence to medical treatment for HIV infection among different populations; and the psychological and psychosocial impact of HIV and AIDS upon individuals, families, and communities.
