Leading figures in the child protection sector are warning of deep concerns that the sexual abuse of children is no longer a priority for many councils and social work departments.

Eight national abuse experts claim a change of emphasis towards other types of abuse such as emotional and physical neglect and away from Child Sexual Abuse (CSA) is misguided.

In a letter to The Herald, they suggest a lack of basic awareness and a shortage of resources may be contributing to the problem.

Martin Henry, manager of national abuse prevention charity Stop It Now Scotland and Laurie Matthew – manager of Dundee-based charity 18 and Under – are among signatories.

Other high-profile figures putting their name to the letter include Anne Houston, chief executive of the charity Children 1st.

Sarah Nelson, of Edinburgh University, is a co-author. She wrote in The Herald's Society page last week that social workers had told her CSA was seen as yesterday's issue.

She said they were "right back to the 1980s in terms of training and awareness" and staff are "afraid to ask families at risk about it because they would have to do something".

In the joint letter they write: "At the very time the Savile revelations have rightly raised expectations for better protection of children in future, we are deeply concerned that sexual abuse is being allowed to disappear off the statutory radar."

The experts blame a trend away from giving social workers the time to listen and form relationships with clients, and say that this makes it difficult to build up a trusting relationship.

As a result, the letter says, it is hard for victims who might otherwise reveal claims of past or current abuse to do so, and to feel confident they will be taken seriously if they do. They add it is misguided to treat CSA in isolation and argue a history of such abuse has been linked to many other social problems –including mental illness, crime and alcohol and drug abuse – that it should not be neglected.

They say: "Different types of child maltreatment should not be in competition with each other for resources, but approached on the basis of need."

The letter calls on the Scottish Government to reverse a decline in prominence for CSA and ensure frontline social workers have sufficient time built into their working day to listen to those who may have suffered child sexual abuse.

Peter MacLeod, president of the Association of Directors of Social Work said: "I don't believe children in Scotland are not being listened to by social work professionals or that allegations of sexual abuse are not being dealt with appropriately.

"But I'm committed to ensuring we do anything we can to make children in Scotland as safe as possible, and as part of that to listen to concerns outlined in this letter."
