ASSESSMENT
Assessing the quantity of exercise alone is not indicative of the level of dysfunctional exercise, as it does not account for the thought patterns and compulsions driving the behaviour(1). To assess and monitor these, there are a range of questionnaires that can be beneficial. A few key questionnaires are:
Exercise dependence scale
Contains 21 statements which are rated on a scale of 1-6, from never to always, and takes approximately 5 minutes to complete(2)
Is based on the criteria for addiction which include the following factors(2):
Tolerance - a need for increased amounts of exercise or a diminished effect of the exercise over time
Withdrawal - presence of withdrawal effects when unable to exercise
Intention effect - engagement in a larger quantity or intensity than intended
Lack of control - difficulties cutting down or controlling exercise
Time - excessive time spent exercising
Reductions in other activities - decreased social, work or recreational activities due to exercise
Continuance - exercise is continued despite causing or exacerbating physical or psychological problems (e.g. running despite injury)
Compulsive exercise test (CET)
Specifically designed for use within the eating disorders domain(3)
Addresses 5 factors that maintain compulsive exercise(3):
Avoidance and rule-driven behaviour e.g. withdrawal effects of not exercising, compulsivity, exercising despite injury and illness
Weight control e.g. exercising to improve appearance, exercise to compensate for food intake
Mood improvement e.g. exercise to decrease anxiety and stress
Lack of exercise enjoyment e.g. finding exercise a chore, not enjoying exercise
Exercise rigidity e.g. set routine, organised and structured exercise
Exercise dependence questionnaire
Consists of 29 items(4)
Addresses the following 8 factors(4):
Interference with social / family / work life
Positive reward following exercise
Withdrawal symptoms
Exercise for weight control
Insight into problem
Exercise for social reasons
Exercise for health reasons
Stereotyped behaviour
Intuitive exercise scale
A 14-item questionnaire, based on 4 factors(5):
Emotional exercise - measures the use of exercise to manage unpleasant emotions
Body trust - assesses reliance on internal bodily cues to guide exercise type, intensity and frequency
Exercise rigidity - measure exercise variety
Mindful exercise - measures awareness of bodily cues and ability to discontinue exercise based on these
