Behaviour Modification is the scientific application of psychological principles especially principles of learning so as to change undesirable behaviours to more desirable behaviours. This is because learning itself is a relatively permanent change in behavioural potentialities as a result of constant interaction with the environment. As a psychological concept, behaviour modification can be used to correct and prevent abnormal behaviour through the use of techniques such as reinforcement, aversive stimulus, modeling, systematic desensitization and relaxation method. Stress on the other hand, is an unpleasant state of emotional and physiological arousal that human being experience in situations that they view as challenging and/or threatening to their lives. Stress, if not well managed can lead to serious health problems such as anxiety disorder, mental illness, heart disease, hypertension (high blood pressure), stomach cramp, suicide, heart diseases and at times life threatening injuries. This paper strongly believes that the systematic application of psychological principles of behaviour modification is capable of reducing stress to the barest minimum and can lead to more harmonious healthful living and form the basis for better coping strategy. In conclusion, causes, prevention and coping strategies were recommended.
