The HSE has confirmed that the support offered to people in the aftermath of the tragedy in Creeslough last month has now been upgraded to focus on the provision of more targeted therapeutic services.
Ten people died in the explosion at a service station and apartment building in the Co Donegal village on 7 October.
In the immediate aftermath of the tragedy, the HSE said that a "Psychological First Aid Support Service" was established on 8 October, which offered support sessions on the phone and in the community (in Letterkenny and Creeslough).
The HSE said this is a WHO recommended response in the immediate aftermath of such an event.
In a statement, it said: "Whilst this service is still available via the Support line (087 140 5138) and in person in Creeslough as required, the response has now been upgraded to focus on the provision of more targeted therapeutic services, by facilitating referrals to clinical services for counselling, trauma therapy (where indicated) and mental health services."
"As is appropriate the psychosocial response to tragedy is multifaceted, with the Psychological First Aid Support Service being only one part of the comprehensive response.
"The nature of the response will changes over time in line with the needs of the community and in line with international best practise "
The HSE said its Primary Care counselling services remain available in Creeslough, Dunfanaghy, Falcarragh and Letterkenny.
