Self Defense Efficacy Research—A Bibliography

This excellent summary of sources on self defense instruction’s benefits and its place in public policy  was compiled by  Katy Mattingly, MSW, instructor of “Violence Prevention in College and Beyond” at the University of Michigan-Ann Arbor. She is also the author of Self-Defense: Steps to Survival.

Prevention Experts & Federal Recommendations

Personal Safety Education is a key recommendation of numerous national experts in violence prevention, public health, sexual violence, criminology, and trauma studies.

Alan Berkowitz recommends that programs for women, in particular, include the following elements of PSE: discussion of effective responses to coercive behavior, overcoming of social norms that reduce self-efficacy, understanding protective and risk behaviors, and learning physical self-defense techniques and skills (Berkowitz, 2001, pp. 85-86).

Judith Herman recommends self-defense in the newest edition of her seminal work Trauma and Recovery, in which she notes that self-defense training can empower survivors to “face their world more confidently” (1997, p. 198).

National prevention expert Gavin De Becker recommends IMPACT Personal Safety Education and further readings on self-defense in his best-seller The Gift of Fear (1997).

Teaching PSE skills has been identified as a promising practice in the same category as Bystander Intervention Education; both are “supported by a preponderance of the evidence” for changing knowledge, attitudes, beliefs, or behavioral intentions and for reducing… victimization,” (Schewe, 2007, p. 227.)

Further, self-defense training has been labeled “one of the most promising interventions to prevent violence against women, particularly sexual assault committed by strangers or acquaintances” (Hollander, 2009, p. 575).

Various federal U.S. institutes, grant-makers and departments recommend that people at high risk for violence practice PSE. In a recent report commissioned by the National Institute of Justice, researchers examined various types of assault against women. They found that certain actions reduce the risk of rape more than 80 percent compared to nonresistance and did not significantly increase the risk of serious injury to the defender (Kleck & Tark, 2005).

The most effective actions, according to survivors, are attacking or struggling against their attacker, running away, and verbally warning the attacker (all actions which are taught and practiced in Personal Safety Education).

Further, while the Department of Justice once identified self-defense-styles of PSE as an example of victim-blaming programming which would not be funded, in recent years they have moved from such a stance. Their 2012 solicitation for Campus Grants no longer disallows such programming, but cautions only that any funded self-defense programs must not be mandatorynor the sole Prevention program available for students on campus.[1]

Academic Literature

A number of studies have found evidence that self-defense training, specifically, may decrease a woman’s chances of experiencing future sexual victimization as compared to women without training; and that forceful verbal and physical resistance and fleeing (all taught and practiced in PSE) have a proven association with rape avoidance in both reported and unreported crimes (Bart & O’Brien, 1993; Brecklin & Ullman, 2005; Ullman & Knight, 1993; Orchowski, Gidycz & Raffle, 2008; Peri, 1991; Zoucha-Jensen & Coyne, 1993).

Low utilization of self-protective dating behaviors (including those taught and practiced in PSE) is associated with more frequent sexual victimization (Orchowski, Untied, & Gidycz, 2011).

Additionally, self-defense has been empirically proven to decrease a number of psychological attributes that are associated with victimization (Brecklin, 2008; Ozer & Bandura 1990; Sochting, Fairbrother & Koch, 2004; Ullman, 2007).

PSE programs may increase assertiveness, perceived control, self-efficacy, risk avoidance behaviors, confidence, and self-esteem, and may also lower anxiety and fear (Brecklin, 2008; Hollander, 2004). Importantly, low self-esteem and low assertiveness have been found to be predictive of victimization (Brecklin & Ullman, 2005).

Unfortunately, crime prevention effectiveness is a difficult topic to quantify, as successful risk reduction or escape from violent situations is rarely reported as such. Experts believe women successfully resist at least 75% of all attempted sexual assaults (Bart & O’Brien, 1993; Gordon & Riger, 1989; Ullman 1997). Such was the case during the well-publicized Ann Arbor attacks of 2011; 5 out of 6 of the assailant’s intended victims successfully employed Personal Safety strategies to end the assault.[2]

Survivors of intimate partner violence similarly employ many different active and creative self-protective strategies both to resist and to escape violence (Campbell, Rose, Kub, & Nedd, 1998; Cook, Woolard, & McCollum, 2004; Gondolf, 1988; Jones, 1994; Hollander, 2005).

Case Study — University of Oregon

One well-known and widely respected academic PSE class reveals additional important supporting research. This upper level, 4-credit Women’s Studies class was taught by the author of Self-Defense from the Inside Out. Nadia Telsey is a national expert on non-violence and personal safety, and a founder of the National Women’s Martial Arts Federation[3] who taught at the University of Oregon for 17 years. Her course included 45 hours of instruction in PSE over a 10 week academic quarter. This women-only class included 3 hours per week of physical and verbal PSE training plus a required weekly 1.5 hour discussion section.

Deep and broad learning outcomes for students were revealed in a qualitative, longitudinal study. Researchers identified five areas in which changes were most striking: “interactions with strangers, interactions with known others (acquaintances, friends, employers, teachers, and intimates), feelings about one’s body, perceived self-confidence, and beliefs about women, men, and gender” (Hollander, 2004, p. 212).

Risk Reduction

Self-defense programs may increase assertiveness, perceived control, self-efficacy, risk avoidance behaviors, confidence, and self-esteem, and may also lower anxiety and fear (Brecklin, 2008; Hollander, 2004). Importantly, low self-esteem and low assertiveness have been found to be predictive of sexual victimization (Brecklin & Ullman, 2005).
