A Correlational study to investigate the relationship between stress and physical illness | |

Life transitions and stress

The assignment aim is to investigate the relationship between stress and physical illness, stress is the body’s reaction to a change that requires a physical, mental or emotional adjustment or response. It can be a difficult term to define; it is both a psychological and physiological response to the environment. The research study carried out by Holmes and Rahe (1967), used the Social Readjustment Rating Scale (SRRS) and believed that the degree of stress was related to both physical and psychological illness. People who have symptoms of being ill follow a period of stress, and the greater the stress the more serious the nature of the illness will be. They surveyed more than 5,000 medical patients and asked them to say whether they had experience any of a series of 43 life events in the previous two years.

The alternative hypothesis:
There will be a positive correlation between stress and physical illness will be found The Null hypothesis:
There will not be a positive correlation between stress and physical illness and the result will be due to chance

The design for this research is a positive correlation study based on two questionnaires; Stress questionnaire (see appendix I) and a physical illness (see appendix II) questionnaire to produce quantitative data. Stress is the amount of time it takes to recover from an event, this is adapted based on Holmes and Rhayes (SRRS) ideas of stress. Physical illness

The British psychology society code of ethics and conduct was followed and all participants were provided with guidelines of codes of conducts to ensure the research study is fully protected from any harm it may cause people. Participates were given a

The study was carried out from adult students attending a rural FE college, 33 participates both male and female, 17 being male and 16 being females . No participants were rejected. Apparatus:
The two scales will be carried out in the college library/
* Physical illness questionnaire
* Stress questionnaire
* Pens
* Participant information sheet
* Consent form
* Debrief form
* Stop watch
An information poster was displayed at college offering students to participate in a research study that needed to be carried out. Participants are picked at random from reply emails asking if they over eighteen and were sent a consent form to sign, participants information form with an information sheet. If participates agreed to take part after explaining the ethical information they emailed the address given within 7 days. Once consent form was signed agreeing to take part they were given the date of the study. The two questionnaires were carried out in the college library. On the day participants were asked individually if they had any questions and to check through the participants information form, they had ten minutes to complete each questionnaire. The questionnaire was carried out using standardised instructions which were given to the participants (see Appendix VI) After the questionnaires were completed all participants were thanked for taking part and giving a debriefing form.

A correlation coefficient was calculated and the value of r = 0.23 with degrees of freedom (n-2) being 31 this is not significant at the 95% certainty level. The results show that there is not a significant positive correlation between life change unit scores and physical illness scores. Therefore the alternative hypothesis can be rejected and the null hypothesis should be accepted.
