An experiment is reported that attempts to distinguish between anxious and depressive future thinking in terms of anticipation of future positive and future negative experiences. Anxious, mixed (anxious-depressed), and control participants were given an adapted verbal fluency paradigm to examine the ease with which they could think of future positive and negative personal experiences. Anxious participants differed from controls only in anticipating more future negative experiences; mixed participants showed both greater anticipation of negative experiences and reduced anticipation of positive experiences. Self-report measures of hopelessness and worry followed a similar pattern to future positive and future negative anticipation, respectively. The results are discussed in terms of the distinction between positive affect and negative affect (D. Watson, L. A. Clark, & G. Carey, 1988).
Brief cognitive behaviour therapy is of limited efficacy in reducing self-harm repetition, but the findings taken in conjunctin with the economic evaluation (Byford et al. 2003) indicate superiority of MACT over TAU in terms of cost and effectiveness combined.
This experiment examines one component of worry, elevated subjective probabilities of negative events, and attempts to elucidate the cognitive processes on which this is based. The results suggest that the pessimistic subjective probabilities shown by chronic worriers can be understood using general theories of judgment, specifically, by the use of the availability heuristic (Tversky & Kahneman, 1973). However, it is the availability of a particular pattern of cognitions--an increased accessibility of explanations for why a negative event would occur, combined with a reduced accessibility of explanations for why it would not--that is important. The results are integrated within a description of the worry process, and possible clinical applications through the use of reason-generation techniques are discussed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
