The Spectrum of Prevention is a framework designed to address public health issues by guiding efforts to prevent harmful behaviors across multiple levels of society. It was created by Larry Cohen, the founder of the Prevention Institute, in the 1990s. The Spectrum emphasizes the importance of comprehensive, multi-level strategies to prevent problems like sexual violence, substance abuse, and other public health concerns, rather than focusing on just one intervention or level of society.

The Spectrum consists of six key strategies (adapted below):

1. Strengthening Individual Awareness and Skills: Empowering individuals with the information and tools needed to prevent harm, including raising awareness of resources, interpersonal effectiveness skills, and conflict negotiation.
2. Promoting Community Education: Increasing collective capacity and educating the broader community to build understanding of the issue and create a culture of prevention.
3. Educating Providers and Professionals: Training institution/organization members (e.g., educators, healthcare workers, counselors) to identify warning signs and provide the necessary support to those affected.
4. Fostering Coalitions and Networks: Building alliances among community groups, agencies, and organizations to create a unified approach to prevention.
5. Improving Organizational Practices: Altering norms and practices within institutions (e.g., schools, workplaces, or hospitals) to support prevention and improve responses to issues like violence or harassment.
6. Shaping Policies: Advocating for improvements to policies and regulations that affect public health and safety, such as fair and humane regulations, procedures, and protocols.

This framework is used to guide comprehensive prevention efforts across multiple sectors, addressing root causes and fostering long-term change. The Spectrum of Prevention has been widely applied in public health, including efforts to reduce sexual violence on college campuses, promoting both individual and systemic change.

Power-based interpersonal harm, including discrimination, harassment, and violence, is a serious and pervasive issue that requires a comprehensive, multi-tiered approach to prevention. It also demands that we look at contributing factors upstream as well as downstream. Additionally, it is critical to look at underlying conditions that may be less visible but nevertheless contribute to harm and its impact.

You might be wondering where our actions fall in the spectrum of prevention. It’s never too early or too late to consider where we can make a difference in preventing and reducing harm.

The concepts of primary, secondary, and tertiary prevention come from public health frameworks, with each level targeting different stages of risk and intervention. These approaches are integral to creating a safer campus environment and addressing violence and harm at multiple levels.

Primary Prevention: Addressing Root Causes and Promoting Healthy Behaviors Upstream

Primary prevention aims to stop sexual violence before it occurs by addressing its root causes and changing systems, structures, attitudes, and norms that create conditions that give rise to violence. This approach focuses on creating a culture of care, consent, and equity. 

Secondary Prevention: Early Intervention and Addressing Conditions Midstream

Secondary prevention addresses issues that might already be present in the environment, due to historical inequities, existing factors that normalize harm, or a need for education and awareness around how to reduce harm among communities. This level of prevention focuses on early detection, intervention, and support to reduce harm and prevent further escalation of the problem.

Tertiary Prevention: Supporting those Impacted and Reducing Recurrence Downstream

Tertiary prevention focuses on ensuring support for those impacted by violence harm. This can include counseling healing spaces for those impacted by harm, accountability-related measures and support for those who may have caused harm, and space for those who may have witnessed harm or who are supporting those directly impacted. Tertiary prevention aims to reduce the long-term impact of violence on survivors and seeks to end harmful cycles and ensure a safer and more equitable future.

Team Psychological Safety is the shared belief that the environment is safe for interpersonal risk-taking (Edmondson, 2018). What does this mean? When a team environment is psychologically safe, members are more likely to be able to:

• Speak up with questions
• Express ideas and concerns
• Being able to say “I don’t know” or ask for help
• Take accountability when mistakes or errors were made

Why does Team Psychological Safety Matter?

• When people feel safe speaking up and sharing concerns in a team, they are more likely to be active bystanders and intervene when potential harm arises
• Teams that prioritize and practice team psychological safety are likely to have shared understandings of team and community values and norms, making it easier to be more active bystanders and to role model active bystander intervention for others

What do psychologically safe leaders do?

• Acknowledge one’s own mistakes. Showing vulnerability encourages teams to be transparent with their mistakes too.
• Use a Learning Mindset: Treating tasks as learning opportunities and being open and responsive to feedback.
• Establish norms: Make behavioral norms explicit and develop clear roles and processes. Ask and respect how your employees prefer receive feedback.
• Model curiosity: Ask questions, and express genuine interest in the answers. Thank those who ask questions encourage participation.
• Strengths-based approach: Ask “What can we count on each other for?” Help each member understand what they bring to the team.
• Take care of each other: Check in on teammates. Assume positive intent. Use inquiry to understand challenges and mistakes.

Everyone at Harvard deserves to feel safe, valued, and capable of contributing to a caring community. We can show care by speaking up and seeking support when we notice situations that seem inconsistent with community values. These include instances of possible discrimination, bullying, sexual harassment, or other sexual misconduct. One way we can take part in prevention is by being active bystanders. Active bystanders are individuals who:

1. Notice situations where harm may be occurring or may be likely to occur
2. Takes some kind of action to diffuse, disrupt, or discourage the situation from continuing. Bystanders who notice harm may improve the outcome of the situation by actively intervening

By being active bystanders, we are taking part in a shared movement, alongside other collective efforts, to reduce harm in our communities.

How each of us intervenes is influenced by the sense of safety and power we have in a given moment. Therefore, context plays a significant role in whether and how we intervene.

Being an active bystander is most effective when the surrounding environment treats violence and harm prevention as a multipronged effort that also requires structural transformation and culture change. Together, these approaches form the pieces of the prevention puzzle.

So, how can you be an active bystander? Check out the 4D’s Framework below!

Your consent matters, and how we talk about consent matters, too. Consent is a critical part of our everyday lives, and consent is a value we can practice in nearly all of our interactions with others. 

We practice consent when we:

• Are conscious of how we are using our power and influence with others
• Consider another person’s needs
• Honor a person’s agency
• Offer choice where possible
• Respect our own and others’ boundaries
• Lead with inquiry in our interactions with others

Consider how you might practice consent across personal, social, academic, and professional areas of your life. What other areas of your life involve consent? 

• Reflection: Consider the first few hours of your day today. In what ways have you already practiced consent? For example:
  • If you ordered coffee or tea this morning, were you given a choice about how you drink it?
  • If you posted a photo or video of a friend on social media, did you ask for their permission first?
  • If you needed to borrow something from a peer or colleague on campus, did you ask before taking it? Think of as many examples as you can.

When a person’s consent is ignored or violated, their choice and power have been taken away. Every person deserves safety and dignity, and every person deserves to be able to access support if they have experienced interpersonal harm. We can be a community of consent by practicing these values every day and being active bystanders when we notice instances that do not align with our shared values.
