The WAGER, Vol. 18(1) – Disorder or distraction? Experiential Avoidance and problem gambling behaviors

avoidance (EA) refers to an individual’s attempt to avoid internal experiences related
to an event, such as thoughts,
feelings, and physical sensations, by engaging in some other activity (Riley
2012). Researchers have suggested that people can engage in EA through a number
of activities, including sex, drug use, exercise, and gambling (Riley 2012). EA
might therefore be related to the development of gambling problems. This week’s
WAGER reviews a study that explored the relationship between EA and
problem gambling, as well as the relationships between these constructs and
related constructs: thought suppression and mindfulness (Riley 2012).  


convenience sample of 103 treatment-seeking problem gamblers from an outpatient
facility in South Australia
completed a battery of measures to assess their levels of problem gambling and
mindfulness, their tendency to suppress difficult thoughts, and their inability
to take action when faced with “negatively evaluated private events.” Participants
completed the following measures:

  • Dispositional
    EA: Acceptance and Action Questionnaire (AAQ-II; Bond et al. 2011)[1]

    • In this scale, higher scores indicate lower levels of EA.
  • Dispositional
    thought suppression: White Bear Suppression Inventory (WBSI; Wegner and Zanakos
  • Dispositional
    mindfulness: Mindfulness and Attention Awareness Scale (MAAS; Brown and Ryan
  • Problem
    gambling symptomology: Problem Gambling Severity Index (PGSI; Ferris and Wynne

researchers completed multiple regression analyses to explore the relationships
among problem gambling, thought suppression, and mindfulness; and, to examine
whether EA mediated a relationship between thought suppression and problem


Table 1 below shows the relationship (zero order
correlations) between the variables in question. Thought suppression and experiential
avoidance were positively associated with problem gambling
(r’s = .33 and -.43; both p’s < .01). Mindfulness, on the other
hand, was negatively associated with problem gambling (-.39; p < .001).

researchers conducted linear regression analyses to examine potential mediating
relationships. As shown in Tables 2 and 3, EA appears to mediate the
relationships between both thought suppression and mindfulness with problem
gambling. When controlling for EA, the standardized regression coefficients
between the other variable (mindfulness or thought suppression) and problem
gambling decreased and became non-significant.

  • The study may not be generalizable to other populations.
    • 103 is a relatively small sample size and all individuals came from the
      same outpatient facility in South Australia
    • The researchers used a convenience
      sample so the results may not be applicable to all problem gamblers

      • The participants were treatment seeking problem
        gamblers, perhaps those individuals for whom EA functions differently
        would not be seeking treatment.
  • Due
    to the cross-sectional nature of the analysis it is not possible to determine causal
    relationships between EA, thought suppression, and mindfulness and problem


article suggests that pathological gambling is related to experiential
avoidance and thought suppression. The mediational findings suggest a model
whereby people experience intrusive thoughts and attempt to cope with the
distress these thoughts cause by gambling. A more mindful state, however, might
decrease the urge to escape distress and gamble. These models can be applied to
more targeted, and therefore more effective, gambling treatments. Specifically,
incorporating mindfulness-based therapies and acceptance practices into
gambling recovery might help counteract experiential avoidance and draw into
focus the underlying problem that is leading to the problematic behavior.
