This paper is a single-subject design evaluation of my work with a woman known as Paula Cortez. She is a 43-year old Latina woman infected with HIV. This case a complex case which involves a lot of factors such as physical illness, social isolation, mental illness, pregnancy, emotional trauma and limited resources. The single-system subject study aims at investigating Paula’s case and the strategies of intervention to assess the effectiveness of treatment on Paula Cortez.
Problems which are focused on in the treatment
The problems which are focused on in the treatment are critical focus issues that have to be addressed. They include HIV, mental illness, the decision whether to keep the baby or abort, physical health and addressing domestic violence. Another issue of focus is that the baby does not get infected and gets born healthy.
The approach of the intervention
The different approaches of intervention that one can use include giving open-ended questions, recognizing the problems, planning of treatment, gathering information, engagement and collaborating with community resources. Self-evaluation is evident, and outcomes will develop using data collected in one year and two months.
Summary of Reviewed literature
The first single-subject trial paradigm was presented by Fisher in 1945 despite his association with multiple designs. The design has since then been used generally within the educational and social disciplines (DH, 1984). This design has stood out as one to be used to examine medication. For example, gastroenterology, medical treatment, pediatrics, cardiology, family solutions and more. The use of this design in medical treatment encouraged me to select this intervention approach on Paula’s case.
Purpose of conducting single Research Evaluation
Single-system designs can be utilized in the study of behavioral change individuals display as a result of treatment. In the case of Paula Cortez, we use the single-system design to get an analysis of how Paula responds to the treatment given. Data is collected twice when she is not under treatment and when she is under treatment.
Measures used to evaluate the outcome and observe a change
Nature of these measures
There are measurements that are repeated. Before beginning and through medication one should have the ability to estimate the subject’s position on the problem at constant time intervals (Gharebaghy, 2015). These repeated measurements occur at gaps of one month in the case of Paula Cortez. There is also the Baseline Phase which is the phase where the intervention to be examined is not provided to the subject. These measures reflect the status of the customer on the constant variable before the beginning of the medication (Gharebaghy, 2015). The baseline phase in Paula’s case took a few days. There is also the treatment phase. It is the age and day that actual medication takes place. Paula Cortez’s treatment phase is three weeks to four weeks.
Reliability and validity of the measures
Measures are recorded with careful observation thereby being dependable. Information is gathered over particular time episodes and must meet all requirements to form the data of both the baseline and treatment phase.
Obtaining baseline measures
When Paula stops taking her medicine, she takes around two weeks to go back to normal schedule and timely taking of medicines. Her HIV condition got into control right after she received treatment and was able to move the formerly paralyzed limbs. She later delivers a healthy baby girl.
To check Paula’s speed of recovery, follow up measures are essential. I followed up on her by calling her and checking her health condition. There was positive feedback as she was capable of managing her ailment. She gave birth to a healthy baby and made wise and better decisions for her future.
Criteria that was used to determine the success and effectiveness of Intervention
The criteria used to define the efficiency of the intervention were determined by Paula’s response or reaction to intervention. For instance, her HIV got into control upon getting the HAART. This was a positive response. The negative response was that even after medication her ulcers did not improve. When she stopped received HAART, her condition deteriorated. At a certain time when she stopped her medication, she was locked in a hospital room for fifteen days. She was well monitored during these fifteen days, and her medication resumed.
