3.3. Instrumentation
Characteristics of the instruments used in this study are as follows:
- Demographic checklist, including information on age, sex, marital status, level of education, employment status, duration of diagnosis and use of drugs, and having insurance. These data were collected only to report the demographic information of the research subjects.
- The criteria for the clinical stage of the disease: The Hoehn and Yahr scale, which divides the disease into five stages, was presented simply so the subjects could choose the option near to the Patient's condition;
- The Parkinson's Disease Quality of Life Questionnaire (PDQ-39), the gold standard tool for examining the quality of life in people with Parkinson’s disease is the one designed by Jenkinson et al. in 1997 in the UK, known as Parkinson’s Disease Quality of life Questionnaire, which includes 39 questions in 8 aspects: Mobility, Activities of daily living, emotional well-being, stigma, social support, cognition, relationships, bodily discomfort. As this questionnaire is on the Likert scale, the first option indicates the best conditions with a score of zero, and the fifth option indicates the worst conditions with a score of four. In the end, the total score is one hundred points, which indicates the worst state of health, and a score of zero means no problem. The calculation of the score of each dimension is also expressed as a percentage: The total raw score of that part, divided by the maximum score in that dimension, multiplied by 100 (

In a study by Dehghan et al. on assessing the validity and reliability of the Persian version of this tool, Co-efficiency (Cronbach’s alpha) varied from 0.64 to 0.92 and was obtained above 0.70. Convergent validity has varied from 0.38 to 0.83, and in general, the Persian version of this tool is appropriate and acceptable and can be used to examine the quality of life of people with this disease (

In this study, the consent form was completed by the client or a caregiver who was able to read and write. Questionnaires were sent via an online link to clients through social networks.
3.4. Intervention
The content related to self-management education provided by the Mobile Application was extracted from reliable, up-to-date, evidence-based medical, nursing, and rehabilitation references by the author (rehabilitation nurse). The accuracy, precision, and validity of this information were approved by three faculty members of the School of Nursing and Midwifery at the Iran University of Medical Sciences.
In order to design the Mobile application, with the ability to install it on a smartphone under the Android operating system, we consulted with an experienced software engineer. After checking the compatibility of the content placement with the proposed graphics and matching the software standards with the existing content, the initial software was designed. Parkinson’s disease patients have vision difficulties, so the ability to enlarge texts and photos has also been added. The graphic consultant team also did the logo design. With the approval of the mobile application by five professors of the nursing faculty of Iran University of Medical Sciences, the application was made available to the people under research.
This mobile application could be installed on a smartphone running the Android operating system and could be used offline. The main features were: educational content, in Persian, related to (1) familiarity with the disease and symptoms, treatment methods, follow-up and adherence to treatment recommendations; (general overview of the disease); (2) pharmacological treatments (name of the drugs frequently used in this disease, indications, complication, and advice); (3) self-management in Motor symptoms (imbalance, gait disturbance and freezing, bradykinesia, tremor, masked face) including exercise (balance and corrective exercises for whole body), and safety advice; (4) self-management in non-motor symptoms (stress management, living with Parkinson’s disease, relaxation, cardiovascular problems, blood pressure, sleep and fatigue, mood, memory and cognition); (5) general self-management (gastrointestinal symptoms, nutrition management, urinary symptoms, pain, pressure ulcer, speech therapy and swallowing problems, advice about decoration change and taking notes everyday); (6) talk to families and/or caregivers (to prepare and improve conditions, supporting the family in using the application and accompanying the patient in self-management; how to decrease the burden generally); (7) frequently asked questions, and contacting the caring nurse (researcher). This mobile application called "ParkinSeven," was divided into seven sections and presented seven recommendations in each part, providing self-management content to the client at once.
The researcher installed the application and taught us in person for about 20 minutes. They were asked to run the application for certainty. The demographic checklist, clinical stage criteria, and quality of life questionnaire in Parkinson’s disease (PDQ-39) were sent via online links to patients or a caregiver before, one month, and three months after the start of the intervention (12 weeks intervention). The author would support the subjects with a weekly phone call and answering online in order to use the application and check the subjects for keeping up with the intervention.
