Direct care workers (DCW), working in the small assisted living home (ALH), is the population of interest. I am exploring the feasibility of a random sample for interviewing DCWs. My aim is to recruit a variation of participants believed to offer information rich perspectives. For this study, preferred participants are those that may be interested in learning or attending work-related educational events.  I have access to a state database of ALH (10 or less licensed beds) (two attachments). There is no database available for DCWs working in the small assisted living home.  There is no way of knowing how many DCWs work in each ALH.  We do know that there are 304 small ALHs in Pima County acknowledged by DHS (as of 9/1/2019) .  Recognizing that some of the direct care may be performed by ALH direct care managers, this subpopulation will not be included in the initial recruitment activities. 

I am exploring  a random sample strategy in order to identify DCWs working in ALHs in Pima County. This is the area I am requesting guidance.  Not sure how to go about identifying my population of interest.  I have included two databases and a document with more in-depth information about my area of interest.

Initial Meeting

I.  Who:

Client:  Christina Wyles (see above)

Consultants: Lisa, Jason, Gabe, Liyun


II.  When:  23 September, 2019, 3:00pm

III.  Summary of client's problem

Christina is researching the needs of Direct Care Workers (DCW's) in small Assisted Living Homes (ALH's) in Pima County.  Due to very low levels of regulation, little is known about the education and technology needs of this labor segment.  Lack of training and technology negatively impacts quality of care, a problem which will increase as the numbers of seniors needing hands-on care continues to grow.  Christina's ultimate goal is intervention in small ALH's to improve training and increase avaialbility of technology.  She intends to survey DCW's in Pima County, analyze the results, and use the findings to build support for her project.  Desiring to conduct a persuasive and statistically sound analysis, she asked us for help selecting an appropriate population sample of DCW's.  

IV.  Discussion

  • Some difficulties arise in choosing a sample
    • ALH owners/managers are hesitant to submit to surveys of their employees
    • DCW’s are often reluctant to be surveyed
    • Difficult to know which ALH’s to approach, because practical data is unknown (e.g. # licensed homes & beds is known, but #residents per home and level of care per resident is unknown)
  • Christina wants to perform a quantitative analysis of what she considers qualitative information
  • It is important to Christina to interview DCW’s—not managers
  • She wants her data to appropriately represent both urban and rural settings
  • Her main interests are:
    • What are the working conditions of DCW’s in small ALH’s?
    • What is expected of DCW’s who lack training and have low access to technology?
    • “How scared are they?”


V.  Next Steps

We suggested the following:

  • We will recommend sample size proportions for ALH capacity level (#beds) and geographic location
  • If she will share her survey questions with us, we can help formulate them to facilitate coding answers for quantitative analysis
  • A balanced block design might be appropriate, and her survey questions can be geared toward providing factors for subsequent analysis as such
  • We will discuss the problem in class on Wednesday and get back to her with any further questions, and provide our final recommendations within the next two weeks.
