Respondent
Universe:
The
respondent universe for this collection will be all
Hispanic/Latino adults (18 years old and older) who are
year-round residents of Tucson, or Pima County, AZ.
According
to the 2010 U.S. Census, 265,000 individuals living in Pima
County self-identified themselves and family members (living in
the household) as Hispanic or Latino. Allowing for those younger
than 18 years old, the target population for this study is
estimated to be 120,000 individuals.
Sampling
Plan/Procedures:
The
study will be introduced by a series of meetings with key leaders
of the Hispanic community in Pima county, AZ. These key leaders
will be church leaders, community organizers, youth group
leaders, and other influential individuals in the community.
Contact information for these individuals will be obtained
through the outreach programs at the Environmental Education
Exchange, the University of Arizona, and the Juan Bautista de
Anza NHT. The purpose of these contacts is to gain community
support for this study. It is likely that individuals contacted
to participate will ask their community leaders if they know
about this project. An affirmative response and support from
community leaders will lead to fuller participation.
Focus
group participants will be recruited by telephone using a list of
1,260 names obtained from Survey Sampling International (SSI).
To increase our chances of success, we will use a Random Digit
Dial Sample (RDD) frame that will provide landline and wireless
telephone numbers. This will be used to create one of the most
projectable and methodologically sound sampling frames possible.
We will also request a target sample to be based on census data
sample that includes all residents in the county who
self-described themselves as Hispanic or Latino.
From
the list names and phone numbers a bilingual interviewer will
start at the 1st
number and then call every 4th
number on the list. If there is no answer, the number will be
called twice at different times within the next two days. Upon
contact, the interviewer will ask to speak to an adult in the
household (at least 18 years old) with the nearest birthday. If
that person is not Hispanic/Latino it will be noted on the call
data sheet and the next number will be selected.
The
goal is to recruit 40 people to participate in 5 focus groups of
8 persons per group. If a target of 40 participants is not met,
the interviewer return to the beginning of the list and start
with the 2nd
name and phone number and call every 4th
number that follows. This process will continue until a target of
40 eligible individuals who agree to participate in a focus group
can be reached.
To
encourage participation, we will offer $20 incentive to serve as
reimbursement for traveling expenses to attend the focus group
session. A small gift from the Juan Bautista de Anza NHT will
also be presented to all participants as an expression of
appreciation. The Environmental Education Exchange will provide
refreshments. The travel reimbursement and gift will be
specified in the recruitment materials. To be eligible to receive
the reimbursement and gift, each participant will have to fully
complete a focus group session.
Instrument
Administration:
Initial
contacts will consist of a 5 minute telephone call to invite
individuals to participate in the focus group study. A call data
sheet for each contact will be maintained and each person
contacted will be asked to provide their age, gender, and zip
code. We will also ask each person called (whether they agree or
decline to participate) to answer the following questions similar
to those used in the focus group sessions.
Name
at least two National Parks sites you’ve ever visited.
If
you have never visited, please tell me at least two that you’ve
heard of.
Do
you ever use the word “Hispanic” to describe
yourself?
Have
you ever heard of the Juan Bautista Anza National Historic
Trail?
The
individuals accepting the invitation to participate in the focus
groups will be asked to come to one of 5 meetings in the Tucson
area. The meeting will be limited to 8 participants. There will
be 5 focus groups consisting of 8 participants per group with a
total of 40 individuals for the program.
A
set of questions will be used to guide the focus group
discussions. Each
session will take approximately 90 minutes to complete. Focus
groups will be held at either the Environmental Education
Exchange, local libraries, or local community centers. The
sessions will be voice-recorded, transcribed and analyzed. The
responses will be coded in such a way to protect participants’
privacy.
Expected
Response Rate:
It
is expected that each focus group will include approximately 8
participants. It is estimated that 268 individuals will be
contacted to recruit 40 focus group participants. There will be
no attempt to generalize the findings to all Hispanic/Latino
visitors to any of the parks mentioned in this collection. The
findings will be used to provide NPS staff with information that
can be used to develop outreach materials and to understand any
possible barriers that limit Hispanic visitation from the
communities surrounding the park. The
results may also be combined with other preliminary indicators
that could be used to develop a future survey in Hispanic
communities to obtain generalizable data.
A
total of 315 numbers will be randomly selected and called from
the list of 1,260 names purchased from SSI. We anticipate that
47 (15%) of the numbers will be unusable (out of service, wrong
number, etc.); and that 161 (60%) of those contacted will decline
to participate in the survey. All of the individuals refusing to
participate will be asked three non-response bias questions that
will be recorded in a survey log. We are expecting that we can
recruit at least 40 people to participate in one of the five
focus groups. This response rate was estimated based a previous
focus group conducted in an African American community in South
Carolina near Congaree National Park.
