Based on my experience, I have never collected data related to patients or clients before, only studying with the hospital staff, which was less complicated than with the clients. Moreover, my project used paper-based questionnaires without the need for technical skills. However, there are several steps that I want to go back and correct.
First, the protocol discussion. Since all my documents needed to be translated into Portuguese before starting the project, even though I understood the context of my study, participants still misunderstood some questions when filling out the form. Therefore, the questionnaires might need to be revised to collect data more accurately and avoid missing data. Moreover, if I have an opportunity to have the meeting with advisor and the unit representatives (who help me gathering the questionnaires) at the same time, the respondents might understand better about the questionnaires and be able to fill out the form correctly.
Second, regarding the timing of data collection, if I had given participants more time, there would have been fewer missing responses. So, I think I need to improve the data design and work flow to collect the data.
Finally, data manipulation. I analyzed the data myself using SPSS software, even though I had been trained to use it as it was a part of the master program. It would be better to have a deeper understanding of statistical knowledge (statistician was not involve in my project), which would allow me to analyze data more quickly.
