Long Description.

Appendix A

Focus Group Discussion Guide and Interview Guide

Focus Group Discussion Guide

The focus group discussions will be guided by the following sets of questions, depending on the particular group. Each group will start with goals, procedures and introductions.

1. Staff introductions

2. Goals of the group

  • To better understand the victims and perpetrators of assaults on transit, what type(s) of assaults are happening, and where they are occurring.
  • To identify successful strategies to mitigate assaults on transit and how to implement them.

3. Procedures

  • Has anyone been in a focus group before?
  • Our group time will be limited to 90 minutes.
  • No right or wrong answers.
  • Be respectful of other people’s opinions.
  • We want everyone to participate.
  • We will be recording the focus group and taking notes, but all information will be kept confidential.

4. Participant introductions

  • First name (or pseudonym)?
  • What city, agency, or group do you work for/represent?
  • What victim groups do you work with (if applicable)?
  • What is your role with that city, agency, or group?
  • What particular interest do you have regarding transit assaults?

This is followed by some introductory definitions for participants.

5. What is meant by assault? For the purposes of this focus group, we are defining assault as: An attack by one person on another without lawful authority or permission (NTD). We are including both physical and verbal assaults, as well as attempted assault.

Long Description.

Vulnerable Victim Advocates and Security Providers

In this group, the discussion questions will start by talking about the people involved.

1. Victims

  • Who are the victims of assaults?
  • How do the assaults impact the victims?

2. Perpetrators

  • Who are the perpetrators of assault?

Then the discussion will turn to the details of the assaults.

3. What type of assault is occurring?

4. Where are the assaults happening (e.g., on transit property, along the route, to/from bus stops/stations)?

Finally, the group will touch on possible solutions.

5. What are you (or your organization) doing to address assaults on transit?

6. What is the one thing you would like to see transit agencies do (or not do) to prevent assaults (ask each participant to provide a short answer)?

Large & Small Agency Representatives and Transit Labor Union Representatives

In this group, the session will start with a brief overview of what was discussed in the first two focus groups discussing vulnerable victims. Then, the discussion will open with:

1. What stands out to you from these discussions?
Possible follow-up questions: Do the details seem to follow what you have seen? Why or why not?

2. (Show of hands.) Does your agency make any special efforts to address the security concerns these vulnerable groups have?

  • Follow-up question: Tell us more.

3. Are there any vulnerable groups that we may have missed?

4. Has your agency experienced any of the issues discussed? Have you personally witnessed any of the issues discussed?

Next, the group will discuss the types of assault occurring and where the assaults are occurring.

5. What types of assault have been occurring?

6. Where are the assaults happening (e.g., on transit propertylike at stops/stations, on vehicles, or at other properties, on transit vehicles, on sidewalk or pathways to/from bus stops/stations)?

7. What support is being provided to survivors, both public and employees (non-operators)?

Then, the group will switch to talking about solutions.

8. What responses has your agency found to be effective in mitigating assaults?

If prompting is needed:

  • Training for transit employees and staff

    • Campaigns to encourage transit workers (other than vehicle operators) and passengers to report suspicious behavior and packages
    • Campaign to encourage the reporting of assaults
    • Public outreach campaigns to discourage inappropriate behavior
