 Our Research Participants!
          Intro/Background (cont.)
 Workshop emphasis is participant recruitment
  and retention (R&R) in social work
 Goal: To increase success potential for clinical
  trial and other intervention research, avoiding
  studies underpowered to adequately test
       Objective: Tailor R&R to specific populations
       Objective: Tailor R&R to research design and sampling
        strategy plans
        Workshop Intro/Background
   Research education addresses issues
    of design, measurement,
    methodology (e.g., power analysis
    to determine sample sizes needed;
    randomization strategies)
   Doctoral training and research
    textbooks seem to offer LIMITED
    CONTENT on actual practices of
    participant recruitment & retention
    (R&R) in social work intervention
           Intro/Background (cont.)
   Study success is dependent on ability to recruit and
    retain appropriate, sufficient numbers and types of
   Under-powering in intervention studies has been
    termed “unethical” (Halpern, Karlawish, & Berlin,
   “Recruitment” is defined as a continuous process
    from initial recruitment activities through the act of
    randomizing subjects into a clinical trial (Spilker &
    Cramer, 1992) and retaining the representative
   Unfortunately, we too often overestimate our
    ability to recruit, especially since fewer participants
    qualify once eligibility criteria are applied (Spilker &
    Cramer, 1992)
         Intro/Background (cont.)
   Unfortunately, we too
    often overestimate our
    ability to recruit,
    especially since fewer
    participants qualify once
    eligibility criteria are
    applied (Spilker & Cramer,
          Intro/Background (cont.)
   Consequences of this training gap:
       Over-estimating recruitment potential
       Under-estimating recruitment & retention challenges
         • Insufficient financial resources to complete
           recruitment & retention activities
         • Staff numbers, time, effort limits for recruitment,
           retention, and screening out inappropriately
           recruited volunteers
         • Planning and monitoring efforts
         • Recruitment tools poorly adapted for target
          Intro/Background (cont.)
   Consequences (cont.)
       Generalizability of findings:
         • Diverse & representative samples are
           critical to generalizability of
           intervention research results,
         • Segments of the population differ in
           their willingness and ability to
           participate in intervention research
         • This affects both efficacy and
           effectiveness study implications
         Intro/Background (cont.)
For example:
 African Americans are less likely than majority population to
  respond to traditional recruitment approaches (e.g., Brown,
  et al., 2000).
 Among African Americans, those with knowledge of the
  Tuskegee Study were significantly less willing to participate
  in medical research than those with no knowledge of that
  study (e.g., Shavers, Lynch, & Burmeister, 2002)
 Women and older adults respond differently to recruitment
  approaches than men and younger adults
         Intro/Background (cont.)
Example (cont.):
 Positive correlation between responsiveness to recruitment
  and self-identified need for intervention (e.g., Winslow et
  al, 2009).
 Different strategies (proactive versus reactive recruitment)
  elicit individuals at different points in the readiness to
  change and level of problem experienced (e.g., Webb,
  Seigers, & Wood, 2009).
 Responses to recruitment are affected by individuals’ past
  experiences with research participation—especially
  suspicion engendered by “smash & grab” research style
  (presenters’ experience)
          Intro/Background (cont.)
   Consequences (cont.)
       Attrition affects fidelity of group and community level
        interventions (Lauby et al, 1996)
        Intro/Background (cont.)
 We will examine specific techniques for both
  Recruitment and Retention (R&R)
 We will NOT examine several strategies that
  are also important options to consider:
       Respondent-driven sampling (e.g., Tiffany, 2006)
       Community-driven model (e.g., Wyatt et al., 2003)
       Participant registries or “pools” (e.g., Harris, lane,
        & Biaggioni, 2005)
         Intro/Background (cont.)

We will examine R&R in context of IRB concerns
   NO recruitment before approval by IRB
   Human subjects protections
      Ethics and IRBs emphasize “distributive justice”
       aspect of intervention research
      Populations should not be unduly burdened by
       conduct of the research
      Populations should have equal access to the
       potential benefits of the research
   Consenting procedures can affect participant
    enrollment/retention over time
          Intro/Background (cont.)
   We will examine “Cost-effectiveness” of
    recruitment strategies as depending on:
       Financial costs of the media used
       Staff time/effort involved in the media efforts and
        screening of “false positive recruitment”
       Effectiveness in generating the participant types
        and numbers needed
       Effectiveness in generating participants who
        can/will be retained
       Effectiveness in generating participants who can
        provide valid, reliable data; adhere to the
        intervention and throughout follow-up data
        Intro Conclusion: Viewing
        Participant Recruitment as a 4 Phase
1.   Generating initial contacts
2.   Consenting
3.   Screening for eligibility
4.   Enrollment and retention
       Participant Recruitment:
       Phase 1
1. Generating initial contacts: Activities to identify
   and solicit potential participants
 Examples from “wide reach” media (television,
   radio, newspaper, movie theatre advertising,
   “ValPaks,” posters/flyers)
 Direct mailings (and cultural sensitivity)
 Personal face-to-face recruitment appointments
   (used in the jails)
 Agency/practitioner partners and referral
        Participant Recruitment (Phase 1
   Media methods with broad reach, increasing
    relative expense for campaign type:
       Press Releases/Public Service Announcements
       Posters/Flyers/Brochures
       Mail/Email/Print Campaigns
       Bus Placards
       Radio/Television
        Participant Recruitment (Phase 1
   Referral Systems:
       Letters to Practitioners
       Meetings with Practitioners
       Practitioner Reminders (after initial letters and
        Participant Recruitment (Phase 1
1a. Different approaches may be differentially
    effective with different populations
   women vs. men
   racial/ethnic groups (it is not just about
    translation into a familiar language)
   younger vs. older (technology included)
   “stigmatized” populations
   workers (time and day messages are delivered)
   “problem” types (e.g., cognitive)
   social networks (e.g., the jail “gossip” network)
          Press Releases/Public Service
   Purpose
       To attract favorable attention to the research center
        (i.e., Public Relations)
       Publicize opportunities being offered
       To educate the public about intervention research
        and research participation
          Press Releases/Public Service
          Announcements (cont.)
   Advantages
       Low to no direct cost
       Large audience
       Capitalize on something new or different (e.g., the start of a
        new trial)
   Disadvantages
       Press releases may not be considered newsworthy (not
        picked up by reporters)
       Poor planning can leave negative impressions (e.g., generate
        calls that no one is available to answer)

          Participant Recruitment Phase 2:
          IRB & Consent
2. Consenting: Informing potential participants about the
    study, including risks/benefits to themselves
•   Consent as an issue of recruitment and retention:
    •   Respect and truthfulness influence enrollment and retention in
        this study
    •   Influence enrollment in future studies (research infrastructure)
    •   Continuation of process begun with marketing; people can still
        refuse to enroll at this stage
         • Influence of “word of mouth”: barrier to participant access
•   Consent as a data quality issue
         Participant Recruitment Phase 2:
         IRB & Consent (cont.)
Consent as a PROCESS not a single, one-time
  event (i.e., a signed consent form)
     Truly informed consent
       • e.g. signing after each page
       • List of bullets at end of consent: client-
   Reiteration/reminder of consent at each
   Serial consent interviews
       • Rolling consent (“re-consenting”) throughout
         study period
          Participant Recruitment Phase 2:
          IRB & Consent (cont.)
   IRB Role in Review/Approval of
    Participant Advertising
       IRB reviews recruitment procedures
        and contents prior to approval and
        use of materials
       Are recruitment procedures coercive?
       Are benefits stated or implied beyond
        those in the protocol?
       Is access to benefits, risks shared
        equitably across populations?
          Participant Recruitment Phase 2:
          IRB & Consent (cont.)
   Payment may be mentioned but should
    not be emphasized (e.g., use of large or
    bold type)
       Arguments about whether any payment is
        consider coercive or “undue inducement” in
        targeting some populations
          • Distinctions between coercion and undue
       Participants in intervention research are paid
        for their time and effort in the completion of
         • Payment for treatment?
         • Appropriate payment schedule? Depends on
           population, time, participant burden…
         • Type of payment and safety issues
          Participant Recruitment Phase 3:
3. Screening for eligibility: Determining whether
   or not potential participants are eligible for
   study participation
    •   Screening as inoculation
   Maximizing diversity while minimizing
    unnecessary exclusion
       Avoiding “creamed” samples
   Flexible screening procedures
       Repeat screening of ‘ineligibles’ due to temporary
   Informing individuals who are study ineligible
             Participant Recruitment Phase 3:
             Screening (cont.)
   Cost Efficiency
       Prescreening potential participants (e.g. phone
         • For example, in one study, 359 potential
           participants were telephone prescreened.
           216/359 progressed to a scheduled screening
           appointment; eventually 133/216 were enrolled.
       Order of screening procedures
         • Cost-efficient: Measures that have most ability to
           discriminate between eligible and non-eligible
         • Must be careful if nature of study may encourage
           people to self-select out unnecessarily
            Participant Recruitment Phase 3:
            Screening (cont.)
   Relationship between screening as part of
    the recruitment process and the retention of
    intervention participants
       Often first “personal” encounter with potential
        participants: persuasive argument (but not too
         • Personal treatment: rapport and listening
         • Belief of how data will be handled based on staff
           conduct at screen
         • Potential participant may be picturing what it
           would be like to spend (a lot of) time with
           you/your staff: need to rise to the challenge…
         Participant Recruitment Phase 4:
         Enrollment & Retention
4. Enrollment and retention:
   Randomizing eligible participants
   to intervention conditions and
   retaining them in the study
     Identification and problem-solving
      of barriers to participation early in
      study involvement
     Minimize time between screen,
      enrollment and study participation
           Participant Recruitment Phase 4:
           Enrollment & Retention, cont.
   Setting up tracking (“locator”) systems
       Database
         • Multiple contacts identified by participant
         • Community-based organizations (access
            • Staff
            • Other clients of CBO
         • Subscription databases (e.g. Accurint)
   When participant “tracking” can
    become participant “harassment”
         Participant Recruitment Phase 4:
         Enrollment & Retention (cont.)
   Sample letters “from”
    participants for
    research team to give
    to their identified
    “significant others”
    giving their
    permission to provide
    team with contact

        Monitoring “Cost-effectiveness”
        of Recruitment Efforts
 Assessing, monitoring effectiveness
 2 Ratios (both have same denominator)
     Recruitment Yield Effectiveness: RYE
    RYE=(# of prescreened calls generated from each media
      method) divided by (number of participants actually
     Recruitment Yield Cost-Effectiveness: RYC
    RYC=(direct advertising US $ cost of each media method

          “Cost-Effectiveness” Case
          Example #1 (cont.)
   Findings/Conclusion #1:
       Local television news appearances, healthcare
        newsletter articles, referrals from providers, and
        press releases were low to no direct cost options for
        subject recruitment
         • television news appearances about the study by
           members of the investigative team and articles in
           healthcare newsletters were extremely effective.
         • Effective methods may still have high indirect costs
           (e.g., staff time in writing newsletters/articles and
           establishing provider referral networks higher than
           direct advertising; screening efforts may be more for
           some options than others)
          “Cost-Effectiveness” Case
          Example #1 (cont.)
   Findings/Conclusion #2:
       Television, newspaper, and radio ads were the most
        effective methods in terms of direct costs per
         • TV and radio are initially more expensive (up front
           production and airtime costs) but when used over
           time, they cost less per subject because of their
         • Newspaper ads also are effective and have lower start-

           Example 2 (cont.)
   Findings/Conclusions
       Referrals from AODA and non-AODA providers as well
        as word of mouth referrals served as low to no direct
        cost options for participant recruitment
         • Provider referrals consisted of staff time in developing
           and maintaining relationships (indirect costs)
       Flyers placed strategically in social services agencies
        were the most effective method in terms of direct
        costs per participant
          Conclusions and Tips:
          Developing a Strategic Plan
   Considerations
       Type and number of participants needed
       Stringency of eligibility criteria (more stringent
        requires more recruitment/retention resource
       Limit the geographic recruitment area (to enhance
        retention in longitudinal intervention studies—
        proximity to treatment sites)
       Ensuring adequate resources involves staff effort and
       Conclusions and Tips:
       Developing a Strategic Plan (cont.)
 Realistically estimate the number of subjects to
  be recruited, estimate attrition rates carefully &
 Have specific staff members dedicated to
  recruitment efforts
 Track/monitor recruitment efforts and set
  weekly/monthly recruitment goals
