Transdiagnostic thought processes (Harvey, Watkins, Mansell, & Shafran, 2006)
• Positive and negative metacognitive beliefs• Recurrent thinking
Transdiagnostic constructs
• A transdiagnostic examination of intolerance of uncertainty across anxiety and depressive disorders (Mahoney & McEvoy, 2012)
• Depressive rumination and co-morbidity: Evidence for brooding as a transdiagnostic process (Watkins, 2009)
• Rumination as a transdiagnostic factor in depression and anxiety (McLaughlin & Nolen-Hoeksema, 2011)
• Perfectionism as a transdiagnostic process: A clinical review (Egan, Wade, & Shafran, 2011)
The transdiagnostic approach

PERSEVERATION Repetitive and persistent thought or behavior, which the
individual finds difficult to control (Davey, 2006)
Catastrophising (Davey & Levy 1998)
Obsessions(Brown, Moras, Zinbarg & Barlow, 1993)
Compulsions (Tallis & de Silva, 1992)
Depressive rumination(Nolen-Hoeksema, 1991;
Watkins, 2008 )

What is mood-as-input?
• Model of task perseveration(Martin, Ward, Achee, & Wyer, 1993)Q: Why do people persevere at a task for longer than is useful? i.e. worrying, checking…
• Use mood to gauge if completed task goals • Positive moods = Progression • Negative mood = Lack of achievement
• Example: Negative and positive mood in different contexts

Mood-as-input and task perseveration (Martin, Achee, Ward, & Wyer, 1993)
Prediction: The informative properties of mood will change with the context
![Page 8: Dr Frances Meeten University of Sussex f.m.meeten@sussex.ac.uk MOOD-AS-INPUT THEORY A transdiagnostic model](https://reader037.vdocument.in/reader037/viewer/2022102805/5517e615550346cb568b4721/html5/thumbnails/8.jpg)
Stop Rules
• When we start an open-ended task we have ‘goals’
• ‘I must do this as well as I can’(performance focused) OR • ‘I will do this until I no longer feel like continuing’(task
focused)
• ‘As Many as Can’ (AMA) OR ‘Feel Like Continuing’ (FL)
![Page 9: Dr Frances Meeten University of Sussex f.m.meeten@sussex.ac.uk MOOD-AS-INPUT THEORY A transdiagnostic model](https://reader037.vdocument.in/reader037/viewer/2022102805/5517e615550346cb568b4721/html5/thumbnails/9.jpg)
AMA stop rules in psychopathology
• Why AMA?
• Individuals with common perseverative psychopathologies experience dispositional characteristics that are likely to give rise to the deployment of AMA stop rules
E.g. Inflated responsibilityIntolerance of uncertaintyClinical perfectionism Poor problem solving confidenceMetacognitive beliefs about the benefits of worrying, or
checking etc.

Predictions from the MAI model
• Psychopathology-relevant tasks are often conducted under conditions of ‘as many as can’ stop rules and negative mood
• Mood-as-input as applied to the generation of perseverative disorders
![Page 11: Dr Frances Meeten University of Sussex f.m.meeten@sussex.ac.uk MOOD-AS-INPUT THEORY A transdiagnostic model](https://reader037.vdocument.in/reader037/viewer/2022102805/5517e615550346cb568b4721/html5/thumbnails/11.jpg)
Experimental work
• Open-ended laboratory-based perseverative tasks
• Catastrophic worry• Perseverative checking• Depressive rumination

Common questionsHow do people ever stop?• Davey et al, 2007: Worriers shift from AMA to FL
Is mood always used as a source of information?• Discounting hypothesis • High level of expertise
![Page 17: Dr Frances Meeten University of Sussex f.m.meeten@sussex.ac.uk MOOD-AS-INPUT THEORY A transdiagnostic model](https://reader037.vdocument.in/reader037/viewer/2022102805/5517e615550346cb568b4721/html5/thumbnails/17.jpg)
Summary of findings
• Mood interacts with stop rules to generate perseveration at a number of psychopathology relevant tasks
• Dispositional characteristics of those who experience anxious psychopathologies indicate a likelihood to adopt AMA stop rule use
• Transdiagnostic mechanism? Negative mood and stop rule interaction reliably demonstrates task perseveration

Mood-as-input based intervention(Dash, Meeten, Davey, & Jones, in prep)
• Socialisation to the mood-as-input model as a method for reducing worry
• A brief 4-session experiment with high worriers (PSWQ > 62)
• Primary outcome measure: Penn State Worry Questionnaire
Predictions1. Socialisation to the model would improve worry as
compared to controls2. Applying techniques based on mood-as-input
theory would reduce worry

Primary outcome measure difference scoresDifference scores between Time 1 PSWQ scores and Time 6 PSWQ scores.Positive values indicate a decrease in PSWQ scores and negative values an increase in PSWQ scores.

Future directions
• Application to other areas of psychopathology
• One size is never going to fit all
• Addressing common underlying mechanisms is a useful tool in a treatment package
• A transdiagnostic mechanism of perseveration generation?
• Implications for treatment
