Comparing thought suppression and acceptance as coping techniques for food cravings.

Handling food cravings seems to play a major role in weight management. Many try to simply avoid cravings. However, avoidance based techniques like thought suppression can make attempts to deal with cravings more difficult. Recent research suggests that acceptance based techniques, such as defusion, may be a plausible alternative. The current study aimed to compare these two techniques. Participants were instructed in either a thought suppression or defusion technique at the beginning of a week-long period of attempted chocolate abstinence. A control group was given no instruction. It was predicted that the participants given the defusion intervention would eat less chocolate during six days and during a final taste test. It was found that participants in the defusion group ate significantly less chocolate during the taste test than other groups. However, no difference was found in the amount of chocolate eaten throughout the duration of the experiment. The results are discussed in terms of the possible utility of acceptance based techniques in promoting weight management.

Mindful maths: Reducing the impact of stereotype threat through a mindfulness exercise

Individuals who experience stereotype threat - the pressure resulting from social comparisons that are perceived as unfavourable - show performance decrements across a wide range of tasks. One account of this effect is that the cognitive pressure triggered by such threat drains the same cognitive (or working-memory) resources that are implicated in the respective task. The present study investigates whether mindfulness can be used to moderate stereotype threat, as mindfulness has previously been shown to alleviate working-memory load. Our results show that performance decrements that typically occur under stereotype threat can indeed be reversed when the individual engages in a brief (5 min) mindfulness task. The theoretical implications of our findings are discussed.

The derived generalization of thought suppression

Thought suppression appears to be a relatively ineffective and even counterproductive strategy for dealing with unwanted thoughts. However, the psychological processes responsible for unsuccessful suppression are still underspecified. One process that may be implicated is derived stimulus relations, which may underlie the formation of unintentional relations that act to hamper suppression attempts. To test this prediction, participants were trained and tested for the formation of three derived equivalence relations using a match-to-sample procedure. Subsequently, they were instructed to suppress all thoughts of a particular target word that was a member of one of the three relations and were also allowed to selectively remove words that appeared on a computer screen in front of them by pressing the space bar. Results showed, as predicted, that participants not only removed the to-be-suppressed stimulus, but also removed words in derived relations with that stimulus, thus showing transformation of suppression/interference functions via derived equivalence. The theoretical implications of this demonstration, including its potential as a model for a key psychological process involved in unsuccessful thought suppression, are discussed.

Experiential Avoidance as a Common Psychological Process in European Cultures

Experiential avoidance, the tendency to rigidly escape or avoid private psychological experiences, represents one of the most prominent transdiagnostic psychological processes with a known role in a wide variety of psychological disorders and practical contexts. Experiential avoidance is argued to be based on a fundamental verbal/cognitive process: an overextension of verbal problem solving into the world within. Although cultures apparently differ in their patterns of emotional expression, to the extent that experiential avoidance is based on a fundamental verbal/cognitive process, measures of this process should be comparable across countries, with similar relationships to health outcomes regardless of the language community. This research tests this view in European countries. The psychometric properties of the Acceptance and Action Questionnaire-II, a measure of experiential avoidance, are compared across six languages and seven European countries, for a total of 2,170 nonclinical participants. Multiple group analysis showed that the instrument can be considered invariant across the language samples. The questionnaire constitutes a unidimensional instrument with similar relationships to psychopathology, and has good and very similar psychometric properties in each assessed country. Experiential avoidance reveals not just as transdiagnostic, but also as a transcultural process independent of a specific language community.

Comparing thought suppression and mindfulness as coping techniques for spider fear

The current study compared thought suppression, focused attention (mindfulness) and unfocused attention as strategies for managing spider fear. Spider fearful participants were exposed to a strategy induction before completing a Behavioural Approach Test (BAT). The BAT is a 10 step measurement of how close participants are willing to move towards a spider. Participants were instructed to use what they learned in the pre-BAT induction to help them advance through the steps of the BAT. The results of the study indicated that participants given the thought suppression or the unfocused attention induction moved through significantly less steps of the BAT than did those given the focused attention (mindful) induction. Additionally, the thought suppression group felt significantly more anxious than the focused and unfocused attention groups following completion of the BAT. These results are discussed in terms of the impact of thought suppression on avoidance behaviour in phobias.

Using Brief Cognitive Restructuring and Cognitive Defusion Techniques to Cope With Negative Thoughts

Negative thoughts, experienced by 80% to 99% of the non-clinical population, have been linked to the development of psychopathology. The current study aimed to compare a cognitive restructuring and cognitive defusion technique for coping with a personally relevant negative thought. Over a 5-day period, participants used either a restructuring, defusion, or control strategy to manage a negative thought. Pre- and post-intervention participants reported (a) believability of the thought, (b) discomfort associated with the thought, (c) negativity associated with the thought, and (d) willingness to experience the thought. Daily online questionnaires assessing the total frequency of negative thought intrusions and their level of willingness to experience the negative thought were also used. Also, 10 positive and negative self-statements were rated on the same scales, and self-report measures of mood and psychological flexibility were completed. Findings indicated that defusion lowered believability, increased comfort and willingness to have the target thought, and increased positive affect significantly more than the control and cognitive restructuring. Within groups, cognitive restructuring also made significant gains in target thought discomfort, negativity, and “willingness to have” in the same direction as defusion but the no-instruction control did not. Negative thought frequency was reduced in the defusion group, maintained in the restructuring group, and increased in the no-instruction control group. Similar trends emerged from the secondary outcome measures, that is, the effects of the strategies on the positive and negative self-statements. The current findings support the efficacy of using defusion as a strategy for managing negative thoughts.

Mindfulness reduces the correspondence bias

The correspondence bias (CB) refers to the idea that people sometimes give undue weight to dispositional rather than situational factors when explaining behaviours and attitudes. Three experiments examined whether mindfulness, a non-judgmental focus on the present moment, could reduce the CB. Participants engaged in a brief mindfulness exercise (the raisin task), a control task, or an attention to detail task before completing a typical CB measure involving an attitude-attribution paradigm. The results indicated that participants in the mindfulness condition experienced a significant reduction in the CB compared to participants in the control or attention to detail conditions. These results suggest that mindfulness training can play a unique role in reducing social biases related to person perception.

The Three Waves

While the dominant psychoanalytical model of the early 20th century developed mostly from the clinical interactions of Freud and his patients, behaviour therapy emerged from the experimental psychology of John Watson. Watson had come into contact with the work of Ivan Pavlov and, although he was initially of the opinion that Pavlov’s results were more physiological than psychological, he came to employ similar experimental conditions with his work in the USA. Watson viewed psychology as “a purely directive experimental branch of natural science” (Watson, 1913, p. 158) in reaction to the psychoanalytical models of the time. His manifest states that psychology should look at covert behaviour, and not bother itself with introspection and the experience of consciousness (Watson, 1913). The predominant interpretation of Watson’s manifest, which has been debated over time (Barrett, 2012), was that he refused to allow any sort of information not available to the outside observer to be used in psychology. Watson’s importance for behaviour therapy, beyond a first formulation of behaviourism, is in his experiment with “Little Albert” (Watson & Rayner, 1920), a nine-month-old child who was experimentally conditioned to fear a white rat.

Acceptance and Commitment Therapy: Applications for Educational Psychologists within Schools

ABSTRACT Guidance for schools regarding the promotion and enhancement of psychological wellbeing represents an invitation to intervene to promote effective, evidence-informed, whole-school approaches for school staff, students and parents. With its transdiagnostic approach and evidence from empirical literature, Acceptance and Commitment Therapy (ACT) is asserted as a coherent psychological model that has potential to support schools in developing effective and sustainable practices to promote psychological wellbeing. Three ways of applying ACT within educational contexts are discussed, demonstrating potential utility of the model: supporting school staff wellbeing; targeted interventions for children and young people; and a potential universal application, through the development of an ACT-based emotional health and wellbeing curriculum.

Cognitive defusion versus experiential avoidance in the reduction of smoking behaviour: an experimental and preliminary investigation

Abstract Background: Brief procedures that reduce smoking behaviour may be useful in reaching the many people that do not seek help for smoking addiction. Objectives: The current study aimed to determine if one component of Acceptance and Commitment Therapy (ACT), cognitive defusion, could be useful in reducing smoking behaviour in a sample of students. Methods: The study employed a between-subjects three-arm design. For one week, participants were asked to reduce their cigarette consumption. To aid them in their reduction, participants were randomly allocated to one of three conditions: the first received a defusion procedure, the second received an experiential avoidance procedure and a control condition received no procedure. For a second week, the instruction to reduce cigarette consumption was lifted. During both weeks participants were required to monitor their smoking behaviour via a tally diary system. Results: The defusion condition smoked significantly less than the control condition during week one and significantly less than the control and experiential avoidance conditions during week two. Conclusion: Results are discussed in terms of the potential utility of defusion in this domain, and the limitations of this preliminary research that would need to be addressed in future investigations.
