Differencesbetween the Types of Study Theories

Fourdifferent theories define research studies. These study approachesinclude descriptive studies, explanatory studies, predictive studiesand prescriptive studies. Each of these is expounded below.


Thistype of research focuses on elucidating the central issues of thestudy. The steps taken involve looking for in-depth information thatcan provide a keen sense of the survey topic. Every informationcollected here has to be factual and not without proper evidence.This study research strategy helps in explaining what the topic underresearch is all about and ensures that any person conducting thestudy will have every detail of it on their fingertips (Yin, 2013).


Theresearch that is done in this section seeks to assess every aspect ofthe topic under study. All the steps that involved the situationbeing studied to come to light, the current impacts that the subjecthas brought about and even the future results that might affect thepeople are described here. The important part of this study is tocreate a deeper knowledge of anyone that might follow be keen on thestudy of what was under research. This study is more theoretical thanpractical (Yin, 2013).


Thetheory behind this study method is to provide a future outlook onwhat can happen if the issue that is being studied maintains itsstatus quo. This research assesses the current figures and data aboutthe underlying study then tries to project these numbers for someyears to see what the results will be like (Yin, 2013).


Thisstudy is more practical than theoretical. It looks into the currentsituation and provides working solutions that can help solve theproblem under research. The research involved here is to bring newways of dealing with the issue under discussion. The recommendationsprovided here are bound to work and permanently eradicate the innateproblem (Yin, 2013).

AnExample of a Predictive Study

Gillespieet al. in the Influence of Personal Characteristics on the Resilienceof Operating Room Nurses: A Predictory Study (2009) attempted to showwhether the flexibility of nurses that are in the operating roomdepends on their experience. The study involved around one thousandand one hundred registered experienced middle level and inexperiencednurses. These nurses underwent intense interviews to determinewhether their experience has played a role in building up theirresilience. The results showed that barely half of the experiencednurses managed to pass the study. The study showed that it was notexperienced that built up resilience or stamina, but the environmentthat the nurses were exposed to and the guidance they had.

Theindependent variable was the inexperienced nurses who were notaffected by the hypothesis of the study that stated that &quotExperiencedNurses had better Resilience than the other Nurses&quot.

Thedependent variable was the experienced nurses who were the mainsubjects of study. The middle level nurses were the median variablesthat gave the relationship between the two nurse distinctions basedon experience.
