Interventions for safer sex behaviors among college students.
Abstract: Safer sex behaviors (monogamy, sexual abstinence, correct and consistent condom usage) are important for prevention of sexually transmitted diseases and HIV/AIDS among college students. The purpose of this article was to review studies addressing interventions for safer sex behaviors among college students. A search of seven databases (CINAHL, MEDLINE, ERIC, Academic Search Premier, Scopus, Web of Science, and Social Sciences Citation Index) was conducted for the time period between 1990 and February 2010. A total 11 intervention studies related to safer sex behaviors were extracted. Information-motivation-behavioral skills model was commonly used for interventions promoting safer sex.

Safer sex is important for protection against STDs (sexually transmitted diseases) and HIV/AIDS (Human Immunodeficiency virus/acquired immunodeficiency syndrome). Consistent and correct condom usage along with a monogamous relationship are two important aspects for STD and HIV/ AIDS prevention. The HIV/AIDS epidemic has grown to alarming proportions. At the start of 2010, there were an estimated 59 million HIV/AIDS cases in 194 reporting countries and territories. Of the 35 million living with HIV infection worldwide, about 3% live in the United States (Stine, 2010). Young adults continue to be a vulnerable population affected by HIV/AIDS. In 2009, about 22,000 adolescents aged 13-24 became infected with the HIV virus (Stine, 2010).

Determinants for engaging in HIV/AIDS related risky sexual behavior in college students are multiple such as low-self esteem and emotional distress (Ethier et al., 2006), gender along with improper social norms and inadequate condom use skills (Dilorio, Dudley & Soet, 2007), and various personality and demographic factors(Mehrotra, Noar, Zimmerman & Palmgreen, 2009). Some of the risk behavior pattern among adolescents' whites and blacks could be differentiated based on factors such as binge drinking, substance use, injection drug use and tobacco use (Hallfors, Iritani, Miller, & Bauer, 2007).

Behavioral interventions in the form of HIV/ AIDS prevention messages significantly improved the likeliness of condom usage among some Indonesian participants but didn't succeed in actual behavioral change (Turk, Ewing, & Newton, 2006). Harm-reduction approaches in HIV/AIDS counseling among adolescents address the barriers they have for engaging in safer sex, focus on perceptions that might affect risky behaviors, focus on safe sex planning and end in referral making (Pinto, 2000). It is in this backdrop that the purpose of this review article is to present studies addressing interventions for safer sex behaviors among college students.


In order to collect materials for this review a detailed search of CINAHL, MEDLINE, ERIC, Academic Search Premier, Scopus, Web of Science, Social Sciences Citation Index databases was carried out for the time period between 1990 and February 2010. A Boolean search strategy, where the key words entered for search were "HIV/AIDS prevention" and "interventions" and "college students" and "safer sex" and "interventions" and "college students" in differing orders was used to extract studies related to interventions for safer sex among college students.

The criteria for inclusion of studies were (1) publication in English language, (2) publication between 1990 and February 2010, (3) location of studies anywhere in the world, and (4) relating to interventions involving college students. Exclusion criteria were publications in languages other than English and studies published prior to 1990. A total of 11 studies met these criteria for interventions related to safer sex behaviors.


The studies that conducted interventions related to promotion of safer sex among college students are presented in Table I chronologically. The first interventional study (Turner, Korpita, Mohn, & Hill, 1993) was a randomized control trial which used a comprehensive health education intervention to alter risky behaviors towards safer sex behaviors which included increased condom usage and sexual abstinence. Te second study (Bryan, Aiken, & West, 1996) used a randomized experimental design to maintained greater sustainability of condom usage behaviors while the third interventional study (Ploem, & Byers, 1997) used information and communication skills training to enhance condom use sustainability. Information-motivation-behavioral skills model was used in the fourth study (Fisher, Fisher, Misovich, Kimble, & Malloy, 1998) for discussing AIDS preventative behaviors and in the fifth study (Singh, 2003) for enhancing self-efficacy towards condom usage. The sixth study (Chernoff, & Davison, 2005) used normative feedback with an unintended effect of decrease in number of sexual partners in women receiving the intervention. The seventh study (Kiene, & Barta, 2006) used computer-tailor based IMB (information-motivation-behavior skills) model to increase safer sex preparatory behaviors. The eight study (Sanderson, & Yopyk, 2007) used condom promotion videotape for enhancing self-efficacy towards condom usage and the ninth study (Labrie, Pederson, Thompson, & Earleywine, 2008) used decisional balance motivational enhancement intervention to increase condom use scores. The tenth study (Schmiege, Levin, Broaddus & Bryan, 2009) used group interventions to reduce HIV/STD risk. This randomized controlled study concluded that group--based psychosocial intervention with an added component of motivational enhancement therapy is better in reducing risky sexual behaviors. The last study (Kanekar, Sharma, Cottrell, Succop, & Bernard, 2010) addressed a vulnerable population of African-American college students. It concluded that there was no difference between a brief theory-based safer sex intervention and a comparison knowledge-based intervention in promoting safer sex behavior.

As shown in Table 2, effects sizes were calculated for all the 11 studies using G-Power analysis software 3.1.2(Erdfelder, Foul, & Buchner, 1996). Sample size, alpha values and power (0.80) were used to conduct the desired calculations.


The purpose of this article was to review studies addressing interventions for safer sex behaviors among college students and also to identify studies addressing interventions conducted among a target population of college students to promote safer sex behaviors (such as sexual abstinence, practicing monogamy and consistent and correct condom usage) between 1990 and February 2010.

Based on this review of intervention literature for safer sex among college students a total of 11 studies could be identified in last 20 years which used some kind of interventional strategy to change attitudes and behaviors of college students towards safer sex. The dearth of intervention literature in population of college students is surprising as we would expect a large number of interventions in these students. All the 11 studies used an experimental design in their interventional approach. A little less than 50 %(5 out of the 11) studies (Fisher, Fisher, Misovich, Kimble, & Malloy, 1998; Kiene, & Barta, 2006; Labrie, Pederson, Thompson, & Earleywine, 2008; Schmiege, Levin, Broaddus, & Bryan, 2009; Singh, 2003) identified, used the information-motivation-behavioral skills enhancement model and motivational component as a part of safer sex promotion tool. The remaining 6 studies used multicomponent (Bryan., Aiken, & West, 1996), normative feedback (Chernoff, & Davison, 2005), information about safer sex (Ploem, & Byers, 1997), condom promotion videotape (Sanderson, & Yopyk, 2007), and a comprehensive health education (Turner, Korpita, Mohn, & Hill, 1993), and theory-based components (Kanekar, Sharma, Cottrell, Succop, & Bernard, 2010).

It seems that the IMB (information-motivation-behavioral skills model has been the most popular model tried among college students to promote safer sex behaviors. This model has been well validated over 15 years of research with diverse populations and cross--cultural settings (Fisher, & Fisher, 2000). It has also shown promise in adults where it builds skills for risk reduction along with lower rates of unprotected intercourse and fewer sexually transmitted infections. Literature on using this model also supports a full model usage against a single component such as information only. (Cornman, Schmiege, Bryan, Benziger, & Fisher, 2007; Kalichman et al., 2005).

Also what was evident from this review was that despite use of theory based predictors for safer sex such as social cognitive variables (O'Leary, Goodhart, Jemmott, & Boccher-Lattimore, 1992 ; Raj, 1996) and health belief model constructs (Boone, & Lefkowitz, 2004), no theory-backed intervention for safer sex among college students could be extracted. Using a theoretical framework is essential when devising interventions as this provides a common language of views and ideas across researchers in safer sex and HIV prevention research. It is extremely important to examine interventions which emphasize key constructs of a theory (Glanz, Rimer, & Vishwanath, 2008). In promoting safer sex a meta-analyses of interventions conducted to increase condom use found that many key constructs of commonly used theories were changed by interventions. (Albarracin et al., 2005). These can be then further explored or rejected (Beaty, Wheeler, & Gaiter, 2004).


This review clearly establishes need for more interventions to promote safer sex behaviors among college students. Knowledge-behavior gap seems to be an important component to be addressed when researchers plan to devise a safer sex intervention. Theory-backed interventions should be seen more for promoting safer sex in the form of increasing condom usage, promoting sexual abstinence or sexual partner reductions (monogamous relationships).


There is a large need of conducting interventions which change the attitudes and behaviors of college students towards safer sex. These interventions should promote protective factors at the same time work towards minimizing risky factors for safe sex behaviors. Future interventions should be based on behavioral change theories which must measure the constructs before and after the intervention to give credence to a theoretical approach as opposed to an atheoretical approach. Intervention researchers use multiple theoretical approaches and it is important that they develop psychometrically robust instruments to measure changes in the theoretical constructs.

In models and theories of health behavior change, a linear relationship is often implied when one assumes that change in constructs of knowledge, attitude, and behavior would lead to a corresponding changed behavior outcome. Complex systems and chaos theory complement the linear effect of behavior change in terms of alternative approaches of addressing any health behavior problem such as quitting tobacco, engaging in physical activity or risk-reduction and substance abuse behaviors (Resnicow, & Page, 2008). Future studies should address this paradigm in a quantitative or a qualitative way to promote healthy behavior change especially in the context of safer sex promotion to prevent sexually transmitted infections including HIV/AIDS among college students.
