THE boss of a parenting support programme has hit back at claims the system is ineffective, and defended a health chief against allegations she acted inappropriately.

Matt Buttery, chief executive of the Triple P scheme described the criticism by Aberdeen University professor Phil Wilson as "misleading".

Mr Wilson made the claims after he resigned from a steering group overseeing the use of the system by NHS Greater Glasgow and Clyde (NHSGGC) with pregnant mothers.

It came after the health board rejected the findings of a £190,000 study the professor co-authored.

It said Triple P had a limited effect for families from deprived background and suffered from a high drop-out rate.

In his resignation letter, Mr Wilson questioned the health board's investment of at least £8 million in the Triple P method, and its rejection of his team's research findings.

He has also queried the ­independence of Dr Linda de Caestecker, the city's head of public health.

In particular, he pointed out that she appears in promotional materials for Triple P.

Yesterday Mr Buttery said: "Triple P UK is concerned about a letter widely circulated by Prof Phil Wilson which includes gross inaccuracies.

"Prof Wilson's statement contains a number of misleading and unsubstantiated allegations and his claims are simply not supported by the facts."

Describing the recent study of Triple P as "incomplete", he said it was co-authored with the author of a rival parenting programme, understood to be Christine Puckering. The ­Glasgow-based psychologist has developed a system called Mellow Parenting.

Mr Buttery added: "Prof Wilson's claims have been refuted in a recent meta-analysis of Triple P, which has been published in a leading high-impact, peer-reviewed scientific journal.

"Triple P UK reiterates its support for the NHSGGC decision to reject the conclusion of a recently released evaluation into Triple P in Glasgow, led by Prof Wilson, because it lacked sufficient rigour and suffered from apparent bias.

"The NHS has said it is considering conducting an independent evaluation of its Parenting Support Framework. We strongly support this suggestion."

Mr Buttery also confirmed Dr Caestecker had appeared in promotional materials for the company, but defended the public health chief.

"We refute any allegation from Professor Wilson that Dr de Caestecker may have acted inappropriately in endorsing Triple P," he said.

"It was right that Dr De Caestecker would talk about why the programme was chosen."
