Abstract
Background and objectives
Mind-wandering, and specifically the frequency and content of mind-wandering, plays an important role in the psychological well-being of individuals. Repetitive negative thinking has been associated with a high risk to develop and maintain Major Depressive Disorder. We here combined paradigms and techniques from cognitive sciences and experimental clinical psychology to study the transdiagnostic psychiatric phenomenon of repetitive negative thinking. This allowed us to investigate the adjustability of the content and characteristics of mind-wandering in individuals varying in their susceptibility to negative affect.
Methods
Participants high (n = 42) or low (n = 40) on their vulnerability for negative affect and depression performed a Sustained Attention to Response Task (SART) after a single session of positive fantasizing and a single session of stress induction in a cross-over design. Affective states were measured before and after the interventions.
Results
After stress, negative affect increased, while after fantasizing both positive affect increased and negative affect decreased. Thoughts were less off-task, past-related and negative after fantasizing compared to after stress. Individuals more susceptible to negative affect showed more off-task thinking after stress than after fantasizing compared to individuals low on this.
Limitations
In this cross-over design, no baseline measurement was included, limiting comparison to ‘uninduced’ mind-wandering. Inclusion of self-related concerns in the SART could have led to negative priming.
Conclusions
Stress-induced negative thinking underlying vulnerability for depression could be partially countered by fantasizing in a non-clinical sample, which may inform the development of treatments for depression and other disorders characterized by maladaptive thinking.
期刊介绍：
The publication of the book Psychotherapy by Reciprocal Inhibition (1958) by the co-founding editor of this Journal, Joseph Wolpe, marked a major change in the understanding and treatment of mental disorders. The book used principles from empirical behavioral science to explain psychopathological phenomena and the resulting explanations were critically tested and used to derive effective treatments. The second half of the 20th century saw this rigorous scientific approach come to fruition. Experimental approaches to psychopathology, in particular those used to test conditioning theories and cognitive theories, have steadily expanded, and experimental analysis of processes characterising and maintaining mental disorders have become an established research area.
