                                                     Roy’s Adaptation Model

There are nursing theorists who have formulated models that have guided nursing research for years. Many of these models present theories on how humans beings behave and adapt and how nursing is tied in to it all. For this discussion post, this writer explored Roy’s Adaptation Model which explains that humans are viewed as biopsychosocial adaptive systems who cope with who cope with environmental change through the process of adaptation (Polit & Beck, 2017). The systems that Roy refers to in human beings are the four subsystems of physiological/physical, self-concept or group identity, role function and interdependence These subsystems provide mechanisms on how humans deal with stimuli from our environment. This model is broken down to show how each change in our environment affects us and how the body deals with it. 

The Physiological subsystem

            This writer, researched how to apply Roy’s Adaptation Model to pregnant women who experience nausea vomiting. Many people were never able to explain how this process occurs and why does it happen to more than a few pregnant women in their first trimester of pregnancy. This article obtained from (Davis, 2014), utilized Roy’s theory to explain how the woman’s body deal with this change during pregnancy. The Physiological subsystem states that nausea and vomiting is related to the increased level of the Human Chorionic Gonadotropin hormone in the body when the woman is pregnant (Davis, 2014). The prolonged nausea and vomiting will subsequently affect the woman’s food intake as the inability to keep the food down deters women away from eating. This ultimately will lead the body into metabolic acidosis from the decreased intake in glucose, and the body now has to burn fat stores for energy (Davis, 2014). As a result of this pregnant women many times end up losing weight.


Nausea and vomiting in pregnancy as it relate to self-concept reflects more on the mother having to spend time nursing themselves back to a healthy state and not spending enough time bonding with their unborn child (Davis, 2014). At this stage many women, may feel the need to end their pregnancy because it is causing them so much discomfort (Davis, 2014). If the woman tries to remedy the problem by taking medications the feeling of guilt may arise as they feel that they have done something to harm their baby. The mother, if she experienced nausea and vomiting throughout the pregnancy may experience some bonding issue with the baby as she was ill throughout most of the pregnancy.

Role Function

Role function as it pertains to nausea and vomiting during pregnancy is explained as the woman feeling that she has lost self-control due to the inability to live up to her roles (Davis, 2014). For example, the woman may not be able to take care of household and career duties which may ultimately affect the control she has over her life.


Roy’s interdependence subsystem explains that while experiencing nausea and vomiting the pregnant woman’s relationship with her mother and spouse are many times disrupted. The cause of this is related to their unwillingness to believe her inability to cope with the ill feelings of nausea and vomiting (Davis, 2014). At many times, her family may believe her symptoms are not as severe as she portrays and this will affect the way they engage with each other.

Basing research off an established model

Basing research off an established model directs the researcher into an area that provides much support for their topic of interest. It provides information that support or offer a base on which the researcher can make comparisons. In addition, it opens up fresh and new perspectives that can enlighten the researcher.  Many of these theorists have tested these theories and applied these models to areas in real life. There is tested evidence available for the researcher to use in support of their research.

In conclusion, Roy’s Adaptive theory provided a new approach on viewing and interpreting many disease states or illnesses. This writer supports this theory, because much of what we experience as humans are rarely just physiological. Most of our illnesses can be explained thoroughly on how it affects our bodies physically but in addition to that, illnesses also affect us psychologically, emotionally, and socially.
