It has also been observed that despite being effectively utilized in the management of mood disorders, such as, anxiety and depression, this approach can actually be very effective as a part of several care regimens in other psychotic illnesses such as schizophrenia (Zimmermann, Favrod, Trieu, & Pomini, 2005). Many studies have been conducted on the topic of efficacy and delivery modes of cognitive behavioural therapy in patients in a range of mental illnesses, and the consensus now is that many such illnesses of diverse etiologies have a cognitive-behavioural component that can be delivered even at the level of community through the mental health professionals who are in close contacts with such individuals across the time spectrum of the care delivery (Wykes, Steel, Everitt, & Tarrier, 2008).
Mental health nurses are in a unique position to deliver such care if they are appropriately informed and trained on the modes of delivery and can drastically alter the care outcomes in these clients. Due mainly to their ongoing relationships with such patients, they can teach them to control distortions of thoughts that may prevent development and maintenance of these mood disorders or alter the consequences of these thought patterns on the processes of other psychotic illnesses.
(Chan & Leung, 2002) In relation to the theoretical context of cognitive behavioural therapy, studies (Hurley et al, 2006) have indicated that all mental illnesses, apart from having other etiological factors involved in clinical presentations, can be modeled according to the basic propositions of cognitive-behavioural theories. It is known that in anxiety disorders, the individual experiences interfere with the ability to function in social, occupational, and vocational areas, and in many cases, these are responsible for the physiological symptoms related to the classical fight-or-flight response (Hurley, Barrett, & Reet, 2006).
This is more so important in cases where medications or other approaches fail to produce desired outcomes leading to severe interference and distress in the lives of the individuals in the social and personal milieus. As far as nursing care is concerned, cognitive impairment needs to be addressed in all such care plans, and the literature in this area suggests that nursing interventions to improve cognitive domain also positively modifies thought and behaviour patterns leading to better therapeutic outcomes (Schneider & Cook, 2008). As Bradshaw and colleague (2004) described, in order to be able to deliver cognitive-behavioural nursing care, the nursing assessment must establish the cognitive-behavioural status through standard assessment tools prior to care planning.
