Study Description

Brief Summary:

Gambling Disorder (GD) is defined as the recurrent and persistent act of betting which leads to clinical impairments,. The latest edition of the Diagnostic and Statistical Manual of Mental Disorders (5th edition) conceptualizes GD as a behavioral addiction due to the similarities between GD and substance addictions in clinical presentation, association with personality factors, genetic transmission and treatment options. Previous studies found potential benefits of physical activity in treatment of addictions in general and GD in particular, such as reducing desire to play, betting and depressive and anxious symptoms.

Condition or disease	Intervention/treatment	Phase
Gambling Disorder	Other: Aerobic; Other: Stretching	Not Applicable

Detailed Description:

Detailed Description: The purpose of this study is to investigate the effects of regular physical activity controlled and supervised in the treatment of gambling disorder with focus on gambling severity, psychiatric comorbidity and impulsiveness. Patients will undergo physical activity either running (experimental) or stretching (control) groups,. Physical activity sessions will be lead by a physical educator., Both groups will receive treatment for psychiatric comorbidities and cognitive behavioral psychoeducation.

Arms and Interventions

Arm	Intervention/treatment
Experimental: Group aerobic activity (experimental); Group aerobic exercise (experimental). Patients perform aerobic exercise per 30 minutes (moderate intensity: 70% to 85% of estimated maximum heart rate), more 10 minutes stretching, once a week monitored and once without monitoring and patients have medical appointment with psychiatrist and make psychotherapy sessions.	Other: Aerobic; Aerobic exercise Patients performs 8 sessions of aerobic exercise (walking / running),with monitoring and 8 sessions without monitoring totaling 16 sessions and patients have medical appointment with psychiatrist and make psychotherapy sessions.
Active Comparator: Group stretching (control); Group stretching (control). Patients perform stretching per 30 minutes, once a week monitored and once without monitoring and patients have medical appointment with psychiatrist and make psychotherapy sessions	Other: Stretching; Stretching Patients performs 8 sessions of stretching, with monitoring and 8 sessions without monitoring totaling 16 sessions and patients have medical appointment with psychiatrist and make psychotherapy sessions.

Outcome Measures

Primary Outcome Measures :

1. Gambling Follow-up scale (GFS) [ Time Frame: Eight weeks ]
   This questionnaire is meant to assess gambling severity and it investigates financial issues, family relationships, emotional distress, and satisfaction with leisure, in addition to gambling behavior.
2. International Neuropsychiatric Interview [ Time Frame: Eight weeks ]
   The MINI is a brief psychiatric interview that has strong psychometric properties including reliable diagnoses as compared to the Composite International Diagnostic Interview and the Structured Clinical Interview for the DSMpsychiatric disorder in axis I of Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) of American Psychiatric Association in 1994. International Neuropsychiatric Interview takes approximately 15 minutes.

Secondary Outcome Measures :

1. Gambling Symptom Assessment Scale (GSA-S). [ Time Frame: Eight weeks ]
   The G-SAS is a 12-item instrument which was designed to evaluate gambling symptoms. Each item is scored on a 5-point Likert scale from 0 'none' or 'complete' to 4 'extreme' or 'no control'. Scores range from 0 to 48 with four severity categories: mild (8-20), moderate (21-30), severe (31-40), and extreme (41-48).
2. Barratt Impulsiveness Scale (BIS-11) [ Time Frame: Eight weeks ]
   It is a self-report scale consisting of 30 questions that provides a total score (minimum of 30 and maximum of 120) resulting from the sum of three sub-factors, namely: lack of attention, that is, cognitive impulsivity (i.e., decisions made in haste), motor impulsivity (i.e., acts without thinking) and non-planning (i.e., behaviors performed without future perspective).
3. GoStop Impulsivity Paradigm. [ Time Frame: Eight weeks ]
   GoStop Impulsivity Paradigm evaluates the capacity of inhibitory control. GoStop Impulsivity Paradigm is a "stop task" designed to measure response inhibition. The primary response of interest here is the failure to inhibit responding when a "go" cue is unexpectedly accompanied by a "stop" cue.
4. Delay DiscountingTask (DDT). [ Time Frame: Eight weeks ]
   In the Delay Discount Test (DDT) the subject is faced with a hypothetical choice, for example receiving US$ 1,000.00 in 6 hours, or US$ 999.00 now. The value of the present reward is presented in descending order until the subject chooses to wait for the delayed reward. The value immediately prior to this change is called the point of indifference.
5. The Rey-Osterrieth Complex Figure Test [ Time Frame: Eight weeks ]
   The Rey-Osterrieth Complex Figure Test assesses visuospatial organization and planning abilities. The subject has to copy a complex geometric figure. A score is calculated for the drawing taking into account number of details, reproduction strategy, and drawing organization.
