This Intervention Review is primarily based on two systematic reviews and 16 primary studies, one of which was published across five documents.
The review draws on the best available impact evaluation evidence. The studies were selected against set selection criteria which is based on a rigorous and comprehensive search and screening process. This review includes impact evaluations of the intervention and therefore does not necessarily reflect all evidence on the intervention. Further materials on this intervention are listed under References and Further Reading.
See the Prevention Evidence and Gap Map to explore similar interventions. For details about the individual studies, see the Included Studies section. For further information about the methods informing this review, please see the Intervention Review Technical Report (forthcoming).
This Intervention Review is comprised of interventions with an educational and risk reduction focus, which often include verbal and physical tactics for resistance. It does not include sexual violence prevention programs that primarily focus on self-defence training without an educational component. Self-defence interventions will be the subject of a forthcoming Intervention Review.

What are the key characteristics of the intervention?
Sexual violence resistance education programs seek to provide women university students with information about sexual violence, the associated risks, and practical self-protective strategies to avoid victimisation or increase personal safety. They also focus on ways to decrease self-blame for women who may have experienced sexual violence. Nearly all programs focused their content on risk reduction of sexual violence perpetrated by “acquaintances” or those known to participants such as classmates, friends and ex- or current intimate partners, rather than strangers.
The programs share common core elements, and generally involve:
Programs often include a component on verbal and physical resistance for sexual violence and feminist self-defence. They generally develop skills in awareness and body language, verbal, and physical techniques for forceful resistance.
Some interventions integrate multiple components of risk reduction from previously tested programs with additional content on emancipatory and positive sexual education that teaches participants about healthy sexual relationships, sex positivity and empowering women’s sexuality.
Some argue that the focus on educating women on strategies to prevent or reduce their own risk of sexual violence victimisation amounts to programs being inherently “victim-blaming”. Others argue that this intervention forms part of a comprehensive approach to prevention to empower women with the knowledge and skills to reduce their potential risk of victimisation.
There has been a shift over time in this thinking, with earlier programs mostly covering content on women’s own resistance to sexual violence. Meanwhile, more recent programs have evolved to include a stronger emphasis on placing the blame firmly with the perpetrator , not victims and survivors.
Where is the intervention set? Tertiary education settings, including universities and colleges |
How is the intervention delivered? By a peer student facilitator or a professional (or both) who are women, in face-to-face groups of 15-30 participants. Often delivered via a presentation or video with interactive activities. |
How frequently is the intervention delivered? Varying frequency and duration, ranging from a single 1-hour session to multiple sessions (i.e., 3-4) up to 12 hours in length. |
What resources and costs are involved? None of the included studies commented on the costs associated with the intervention. |
How is the intervention designed or theorised to work?
The programs in this Intervention Review are based on a number of psychological and behavioural theories, such as: social learning theory, the elaboration likelihood model, the health belief model social cognitive theory, and the theory of planned behaviour. Importantly, the theory of change behind these interventions is firmly grounded in feminist principles and has a strong focus on gender, power and control.
The general premise of these interventions is that providing education about the risk of sexual violence posed to women in tertiary education settings and equipping them with resistance strategies (such as verbal and physical resistance) will reduce potential sexual violence as well as any subsequent self-blame from victimisation.
Most of the programs are based on a sexual assault resistance model called “Assess, Acknowledge, Act”, which encourages women to follow several steps to assess, acknowledge, and act in response to threatening sexual situations. It posits that perpetrators are responsible for sexual assault, but women can nonetheless reduce their risk and implement resistance strategies.
Interventions that include additional components like positive sexuality education or self-defence, focused on physical and verbal resistance tactics are underpinned by principles of empowerment.
This section speaks to the effectiveness of the studies.
The outcomes measured by the included studies include gender-based violence, health, behaviours, knowledge, beliefs and attitudes, wellbeing and emotions, and relationships.
Fifteen primary studies had available quantitative data and were assessed for risk of bias on the ANROWS-IRIS tool. Of these, one received a rating of moderate risk of bias, 11 received a rating of moderate-high, two received a rating of high, and one received a rating of very high.
This means only one study with moderate risk of bias and appropriate outcome data was used for the effectiveness estimate. This study examined the effectiveness of both an enhanced version of the Assess, Acknowledge, Act Sexual Assault Resistance program as well as a basic version of the same program. It conducted a 3-arm randomised controlled trial, comparing both the enhanced and basic programs to the same group of control participants. Results are reported for both versions of the program and across three time-points (immediately post-intervention, 3 months follow-up, and 6 months follow-up).
Although many of the critically appraised studies were randomised controlled trials or quasi-experimental studies, they tended to be rated as a high or moderate risk of bias on the ANROWS-IRIS domains of selection bias, withdrawals and drop-outs, confounders, and intervention fidelity.
In terms of selection bias, some studies included participants that self-selected into the intervention or were not likely to be representative of women university students broadly. Studies also tended not to assess equivalence between the intervention and control groups. Many studies provided no information about whether the students who dropped out of the intervention or control groups were different.
Some studies had cross-contamination, whereby some participants in an intervention group shared knowledge or skills gained via the program with participants in the control group, undermining the integrity of the intervention. Overall, these risks of bias hamper our ability to draw accurate conclusions about the effectiveness of interventions.
Two meta-analyses included in this intervention review were critically appraised on the AMSTAR 2 tool, of which one received a rating of moderate confidence, and one received a rating of critically low confidence.
The moderate rated meta-analysis examined educational programs for preventing violence among both adolescents and young adults in a range of settings (e.g., high schools, universities). It was not possible to include this meta-analysis in the Effectiveness Estimate Scale because the authors did not conduct subgroup analyses. That is, they did not analyse the impact of the intervention specifically by gender or setting to determine whether sexual violence resistance education programs designed for women university students specifically worked. While they intended to do these analyses, not enough studies presented results by gender for it to be possible.

Effectiveness rating | Outcome | Description |
---|---|---|
Fear of rape |
There was no effect of both programs on participants’ fear of rape. There was no significant effect between groups when comparing the enhanced Assess, Acknowledge, Act Sexual Assault Resistance program to the control group. This was true at all timepoints (post-test, 3 months and 6 months). There was no significant effect between groups when comparing the basic Assess, Acknowledge, Act Sexual Assault Resistance program to the control group. This was true at all timepoints (post-test, 3 months and 6 months). |
|
Perceived personal risk of sexual assault |
The study showed decreased perceived risk of rape or sexual assault. There was a positive significant effect of the enhanced Assess, Acknowledge, Act Sexual Assault Resistance program on perceived risk of rape compared to the control group. This was true at all timepoints (post-test, 3 months and 6 months). There was a positive significant effect of the basic Assess, Acknowledge, Act Sexual Assault Resistance program on perceived risk of rape compared to the control group. This was true at all timepoints (post-test, 3 months and 6 months). |
|
Sexual assertiveness |
There was no effect of both programs on participants’ sexual assertiveness. There was a significant effect between groups when comparing the enhanced Assess, Acknowledge, Act Sexual Assault Resistance program to the control group at the 3-month mark. However, this was not sustained at the 6-month mark, which had no effect between groups. There was no significant effect between groups when comparing the basic Assess, Acknowledge, Act Sexual Assault Resistance program to the control group. This was true at all timepoints (3 months and 6 months). |
|
Defence tactic: resistance |
The study showed increased use of direct resistance as a defence tactic. This was measured post-intervention only, so longer term (e.g., 3- or 6-month change) cannot be established. There was a positive significant effect of the enhanced Assess, Acknowledge, Act Sexual Assault Resistance program on use of direct resistance compared to the control group. There was a positive significant effect of the basic Assess, Acknowledge, Act Sexual Assault Resistance program on use of direct resistance compared to the control group. |
|
Defence tactic: forceful verbal tactics |
The study showed increased use of forceful verbal defence tactics. There was a positive significant effect of the enhanced Assess, Acknowledge, Act Sexual Assault Resistance program on use of verbal tactics compared to the control group. There was a positive significant effect of the enhanced Assess, Acknowledge, Act Sexual Assault Resistance program on use of verbal tactics compared to the control group. |
|
Defence tactic: forceful physical tactics |
The study showed increased use of forceful physical defence tactics. There was a positive significant effect of the enhanced Assess, Acknowledge, Act Sexual Assault Resistance program on use of physical tactics compared to the control group. There was a positive significant effect of the enhanced Assess, Acknowledge, Act Sexual Assault Resistance program on use of physical tactics compared to the control group. |
|
Self-defence efficacy |
The study showed increased self-defence efficacy, measured by asking participants about their confidence to take action in various scenarios. There was a positive significant effect of the enhanced Assess, Acknowledge, Act Sexual Assault Resistance program on self-defence efficacy compared to the control group. This was true at both 3-months and 6-months. There was a positive significant effect of the basic Assess, Acknowledge, Act Sexual Assault Resistance program on self-defence efficacy compared to the control group at 3-months. There was no effect at 6-months. |
|
Sexual assault risk detection in a hypothetical situation |
There was no effect of both programs on participants’ sexual assault risk detection in a hypothetical situation. There was no effect of either the enhanced or basic Assess, Acknowledge, Act Sexual Assault Resistance program on sexual assault risk detection in a hypothetical situation immediately post-intervention. |
|
Avoidance of ‘close calls’ for sexual assault |
The study showed increased avoidance of ‘close calls’ for sexual assault. This was not reported for the enhanced Assess, Acknowledge, Act Sexual Assault Resistance program. For the basic Assess, Acknowledge, Act Sexual Assault Resistance program, there was a positive significant effect observed between groups at post-test, 3-months, and 6-months follow-up. |
Has the impact of this intervention been tested with certain key populations?
This Intervention Review assessed the impact of sexual violence resistance education for women in tertiary education settings. Participants are cohorts of university or college students, mostly first-year students ranging in age from 18 to 21 years. Many participants were drawn from cohorts that were studying psychology courses. The interventions were not designed for any specific cultural or ethnic groups, or for people with physical or mental disabilities or health conditions. Many of the programs were delivered to students who were white, young and single.
The table below gives an overview of whether or not the intervention was examined with some key populations. The inclusion of these populations was guided by the National Plan to End Violence against Women and Children 2022-2032 and the Australian National Research Agenda to End Violence against Women and Children: 2023-2028.

All studies examined the effectiveness of the intervention with young women aged up to 25 years. |
|
Culturally and linguistically diverse (CALD) groups |
0 studies examine the effectiveness of the intervention with CALD groups. Therefore, we cannot confirm the applicability of this intervention to this population. |
|
Migrants and refugees |
0 studies examine the effectiveness of the intervention with migrant and refugee communities. Therefore, we cannot confirm the applicability of this intervention to this population. |
|
People with disability |
0 studies examine the effectiveness of the intervention with people with disability. Therefore, we cannot confirm the applicability of this intervention to this population. |
This section summarises factors that may contribute to study results, factors that may be considered to facilitate better outcomes, and the transferability of the intervention to an Australian context.
Available evidence considerations:
There are gaps in knowledge regarding the effect of the intervention on groups such as mature-aged and/or postgraduate, racially and ethnically diverse, and disabled students. Due to the inherent nature of the intervention being designed for tertiary education settings, it is unclear whether the intervention could be transferred to other settings (e.g., high schools or workplaces).
