Brief Summary

Following the realisation that many aspects of the way we live our life, such as our diet, activity levels, and amount of screen time, can have a potent impact on mental health and brain functioning 'lifestyle' based interventions have become topical in medical research. In particular, much scientific attention has been devoted to the impact of physical exercise and various stress reduction techniques on mood disorders. We aim to extend this work and investigate their impact on compulsivity. We will do this by conducting a pilot proof-of-principal intervention study. The study will compare the impact of eight-weeks of:

  • drinking alcohol
  • gambling
  • eating
  • washing or cleaning
  • checking
  • ordering or arranging objects

Study Arms (3)

Physical exercise + stress management activity A

ACTIVE COMPARATOR

Eight week program of concurrent exercise and stress management training.

Behavioral: Physical ExerciseBehavioral: Stress management training A

Physical exercise + stress management activity B

ACTIVE COMPARATOR

Eight week program of concurrent exercise and stress management training.

Behavioral: Physical ExerciseBehavioral: Stress management training B

Lifestyle as usual

NO INTERVENTION

Eight weeks period with no alteration of usual lifestyle. Participants randomized to this arm are eligible for re-randomisation to one of the active conditions at the conclusion of week eight.

Interventions

Physical exercise: Amount of time exercising gradually titrated from 90-minutes in week one to 180-minutes in week eight. Intensity titrated concurrently from 40 - 60% VO2 max in week one to 40 - 90% VO2 max in week eight. Eight week gym membership provided to all participants to facilitate engagement in exercise.

Physical exercise + stress management activity APhysical exercise + stress management activity B

Stress management training A: Daily stress management training for eight weeks with training activity delivered via app. Session lengths titrated from 10-minutes per day in the first week to 20-minutes per day in week eight.

Stress management training B: Daily stress management training for eight weeks with training activity delivered via app. Session lengths titrated from 10-minutes per day in the first week to 20-minutes per day in week eight.
