The best way to find out if someone is experiencing gambling harm is to ask.
Make sure you choose a time when you can talk in private and are both calm.
Before you talk to the person, be prepared for the full range of responses you may encounter, from relief through to anger.
The person may deny, minimise, rationalise, or lie about their gambling or they may blame others.
Be aware that they may feel ashamed or embarrassed and may not want to talk.
Problem gamblers usually only seek formal assistance when there is no other choice.
Psychological distress, financial and relationship breakdowns appear to be the primary motivating factors.
The principal obstacles are reported to be shame and embarrassment, and a false hope in the ability to regain control, or win back losses.
