Craving
Powerful subjective experience that motivates individualsto seek out and achieve a craved target in order to reach
its desired effects (Marlatt, 1987)
The experience of craving is qualitatively similar across a
range of targets and only quantitavely different fromeveryday desires. (e.g. Castellani & Rugle, 1995; Field et al., 2008; May et al., 2004;Moreno et al., 2009)
This construct has been central to analyses of addictive
behaviour and relapse for decades and is a key focus inCBT treatment for addiction (Skinner & Aubin, 2010; OMalley et al., 2002)
It can be the result of the combination of automatic
(conditioned) and voluntary processes (Kavanagh et al., 2005, Caselli &
Spada 2010).

Elaborated-Intrusion Theory of Desire
(Kavanagh et al., 2005)
1. Target- or negative affect-related
cues exposure and associations
2. Break over the awareness
treshold (e.g. intrusive thoughts,
memories, sense of deprivation)
3. Cognitive rigid, perseverative
elaboration of intrusions (desirethinking)
4. Escalation and persistence of
subjective craving and deprivation

Desire Thinking
DTis a voluntary thinking process orienting to prefigure images, information andmemories about positive target-related experience and anticipating how to reach it(Caselli & Spada, 2010; 2011)
I anticipate the sensations I would feel practicing the desired activity
I imagine how I could realize my urges
How could I obtain it?
How could I hide my behaviour?
In the short-term DThelps to manage negative internal states by shifting attention awayfrom them and focusing on positive target related sensations
However in medium-term DT Increases levels of craving and perception of being out of control
Increases accessibility of target-related information
Hinders with down-regulation of desire and craving

Desire Thinking and
Psychopathology Findings on significant structural differences between the construct of
desire thinking and craving (Caselli & Spada, 2011)
DT is associated to level of alcohol use, nicotine dependence, problematic
gambling and internet addiction independently from craving, negativeaffect and gender (Caselli et al., 2011; 2012, 2013, 2014)
The manipulation of desire thinking has a direct effect on craving accross a
range of addictive behaviors (Caselli, Soliani & Spada, 2013).
What make desire thinking becomes perseverative and
poorly regulated?

S-REF Theory(Wells & Matthews, 1994)
A set of metacognitive beliefs act as control components of
information processing modes
They are responsible for psychological disturbance by
developing and maintaining a maladaptive mode of
processing
This maladaptive mode of processing (Cognitive-Attentional
Syndromeor CAS) is constituted by perseverative thinking,
threat monitoring, avoidance or safety behaviours)

The Application of S-REF to Desire Thinking
and Craving
Desire Thinking as a part of the CAS (addiction)
Individuals with addiction disorders would possess both
positive and negative meta-beliefs about desire thinking
(Caselli & Spada, 2010; Spada Caselli & Wells, 2013):
Positive Meta-Beliefs: it helps not to be overhelmed by my
worries, it helps to have a greater control over my
decisions)
Negative Meta-Beliefs:(I cannot stop thinking about my desires,thinking about my desires bring me out of control)

Metacognitions and Addiction
PMB predict desire thinking over and above craving
and negative affect (Caselli & Spada, 2013)
NMB predict addiction severity over and abovecraving, negative affect and desire thinking (Caselli &
Spada, 2013).
Need to Control Thoughts prospectively predict
relapse in alcohol abusers over and above baseline
alcohol use (Spada, Caselli & Wells, 2011)

Aim and Participants
The aim was to test the statistical fit of the metacognitive model of craving
in clinical samples across a range of addictive behaviours: alcohol use
disorder (AUD), Gambling Disorder (GD), Problematic Internet Use (PIU),
Tobacco users (TU)

Discussion
Preliminary cross-sectional support for the validity of the
central structure of the model across four different addictive
behaviors: alcohol, gambling, internet and tobacco.
Absence of the link between PMDT and DT-VP in non-
psychoactive substance related addiction (GD and PIU).
Impact of withdrawal symptoms?
Shortened pathway

Implications
Desire thinking and associated meta-beliefs may be a core
process that discriminate slight experience of
desire/deprivation from excessive craving
Key messages:
1. Desires dontmatter, response to the does
2. We cannot crave less by thinking more about our desires
3. Itsnot good to think too much about a target we do notwant to achieve.

Implications
Improving on-line meta-awareness about (1) desire thinking,
(2) personal goals and decisions
Improving metacognitive control (e.g. postponing any further
elaboration of target-related information)
Modify Meta-Beliefs about uncontrollability, utility and need
to control target-related intrusions

verbal reattribution (Metacognitive Therapy, Wells, 2008).
