The design and implementation of reliable and valid studies in the health sciences is a prerequisite for drawing safe conclusions, improving clinical practice, and implementing rational healthcare. This specific book aims exactly in this direction, as Research Methodology is the most necessary scientific field for conducting studies in a systematic, scientific, and logical way.

More specifically, the successive steps of designing and conducting a study are analyzed, from conceiving the research hypothesis to completing the study. Furthermore, each step is presented in a simple, clear, and detailed manner, using appropriate examples in each case. Specifically, the second revised edition of the book covers both qualitative and quantitative research, allowing readers to understand with simple examples how these two types of research are applied in everyday clinical practice.

The simplicity and clarity of this edition aim particularly to enable even researchers in their early stages, such as health science students, to initially understand the design of studies and then proceed with their implementation.
