Abstract
It is suggested that worry has not been given serious academic attention due to problems of definition, and a prevailing belief that it is an unnecessary addition to the theorists vocabulary given the term “anxiety”. However, an increasing awareness of the importance of cognitive factors in emotional disorders makes the study of worry a necessary endeavour. Furthermore, inclusion of worry in DSM III-R as the principle diagnostic index of Generalised Anxiety Disorder has given the term clinical credibility. Three theoretical approaches to the subject of worry are considered: the test anxiety literature, which has focused on the effects of worry on performance, and two largely clinical accounts, a tripartite theory of worry and anxiety proposed by Borkovec, Metzger, and Pruzinsky (1986), and the model of anxious apprehension proposed by Barlow (1988). All approaches are critically evaluated, and suggestions made for future formulations.
