Question: What is your understanding of what the ‘Vulnerable Stress Model’ postulates? Name: Simone Townsend Course Title: Abnormal Psychology (DGC 411) Facilitator: Miss Caroline Campbell Due Date: November 23, 2015 “… as long as the stress induced by challenging events stays below the threshold of vulnerability, the individual, remains well within the limits of normality. When the stress exceeds the threshold, the person is likely to develop a psychopathological episode of some sort; when the stress abates and sinks below the vulnerability threshold, the episode ends” (Zubin & Spring 1977) The Stress-Vulnerable model (Zubin et al. 1977) is an extremely useful model for identifying and treating relapses of mental illness. It is accepted that humans carry genetic and other predisposition to mental illness. However, the question arises as to how stress impacts on a person in order to cause mental illness to develop. Furthermore, this brings forth the issues of what effects such stress has on the human body beyond the human brain. As the name suggest there are two keys terms involved in this model; ‘Vulnerable’ and ‘Stress’. The term vulnerable refers to our basic susceptibility to mental health disorders. This is determined by our genetic makeup and our early life experiences. It is affected by our use of different kinds of medications and our likelihood of using alcohol or drugs. “Stress” refers to the challenges faced in our lives. It is affected by our coping skills, social support and involvement in meaningful activities. It may also refer to events and experiences that may cause psychological distress. Stress can influence mechanisms that help to maintain the stability of an individual’s cognition, physiology and emotion. (Cindy Goh & Mark Agius) Vulnerability and stress are influenced by many factors that people have some or little control over. Some of these factors include: alcohol, medication use, coping skills, social support, and meaningful activities. When these factors are addressed people can reduce symptoms and relapses and improve the course of their co-occurring disorders. Some people are biologically vulnerable to certain psychiatric disorders, such as: bipolar disorder, major depression, schizophrenia, or anxiety disorders (panic, post-traumatic stress). This vulnerability is determined early in life by a combination of factors, including genetics, prenatal nutrition and stress, birth complications and early experiences in childhood. It is worth noting that the greater a person’s vulnerability to a particular disorder, the earlier it is likely to develop, and more severe it may become. (Stephen W. Porges, PhD) Stress in the environment can worsen biological vulnerability, symptoms and even cause relapses. Stress is anything that challenges a person, to the point where they require some type of adaptation. Serious stressful events include losing a loved one, getting fired from a job, being the victim of a crime or having conflicts with family members or close friends. Stress is often associated with negative events, but positive events and experiences may also be stressful. Take for instance, a student who performs well in school or becoming a parent for the first time; these are two examples of positive stress which later results in negative stress. Stress may also be caused from not having anything to do. When people with cooccurring disorders have nothing purposeful or interesting to do, they tend to have worse symptoms and are more prone to face certain stressors that will lead to using substances that will help to rid the stressful feelings. Stress is a normal part of life. Effective coping enables people to be engaged in interesting, rewarding activities that may involve stress, such as working or being a parent. Coping efforts can make it possible for someone with co-occurring disorders to live a normal life without suffering the negative effects of stress. (Cindy Goh & Mark Agius) Based on the understanding of the stress-vulnerability model, there are many ways to help people manage their psychiatric illness. In the broadest terms, the severity and course of a co-occurring mental health disorder can be improved by reducing biological vulnerability and increasing resiliency against stress. It is impossible to live a life that is free of stress. However, there are many ways people can learn how to deal with stress more effectively and to protect themselves from the effects of stress on worsening symptoms which later results in relapses. Those who do not have high levels of vulnerability are less likely to develop psychological problems when high stress levels are present. When stress levels increase, those individuals who are more vulnerable might be more likely to experience problems. The more vulnerable someone is and the more stress they experience then the more likely they are to experience more distressing symptoms. The stress-vulnerability model explains why it is that some people might experience mental disorders and others do not. To conclude the concept of the relationship between vulnerability and stress seems plausible. The stress-vulnerability model can assist clients as a method of understanding why levels of stress should be monitored. Reference Page Zubin J. & Spring B.
