The "Families Matter" campaign has been launched by Families Against Stress and Trauma (FAST), a community organisation which provides support to vulnerable families and individuals across the country.
It is designed to help young people considering travelling to the region to understand the fear and distress felt by those they leave behind.
FAST also hopes the campaign will encourage concerned families to reach out and seek help.
"While many may be motivated by a desire to help the country, the result and impact on these people, their families and often on the communities they are trying to support is very destructive indeed," he added.

The campaign centres on a short film produced by FAST, which features testimonies from three individuals who talk candidly about the pain and anguish they felt when a family member left the UK bound for Syria.
The Home Office will also be raising awareness of FAST's initiative among community support organisations and women's networks across the UK.
Over 400 UK-linked individuals have now travelled to Syria since the uprising began.
The UK government has stressed that it believes the best way to help Syrians is to donate or volunteer with UK registered charities that have ongoing relief operations.
It has committed over 600million pound worth of aid to alleviate the humanitarian crisis in Syria.
This is being used to provide essential food, clothes and medical supplies.
