BOCA RATON, Fla. -- Disciplining children is a very common problem for parents. According to a new survey, one-third of parents feel their methods are ineffective.

Miami television station WPLG talked to a Boca Raton psychologist who said discipline requires a team effort between parent and child.

Mary Lieberman, 42, of Boca Raton, found that disciplining her daughters, Ana and Rachel, was a challenge.

"Just more listening and respecting the first time you're told to do something is my biggest challenge," said Lieberman.

According to Lieberman, taking away privileges seems to work best.

"The things that I do with Ana is she loves the computer, like most kids. So she'll get grounded from that. She now has a cell phone that will get taken away from her," said Lieberman.

A recent survey, published in the Journal of Clinical Pediatrics, revealed that time outs and removal of privileges are the most popular methods of discipline among parents.

Nine percent of people surveyed spank their children.

Boca Raton psychologist Sharon Fried Buchalter is opposed to that method.

"Physical punishment and name calling, where you're putting somebody down is not effective," said Buchalter.

The author of "Children Are People Too" said the first thing a parent should do is find out what's causing the misbehavior. Then ask the child what can be done to change it.

"So, it's an approach as a team because children that are involved in their own goal setting in dealing with discipline have much higher self-esteem," said Buchalter.

Buchalter said parents should take into account the age and temperament of each child.

She also stressed that parents should:

Remain calm

Never punish in anger

Be fair

Not just discipline, but also teach acceptable behavior

"I think the most important thing is that you are consistent, that the child feels that they're part of the solution and that the family as a whole is functioning effectively," said Buchalter.

Lieberman has found the team approach to be a real winner.

"We talk about what can we do to fix this situation. (We ask) 'What do you think would be the best thing to do that we can work on together?'" said Liberman.

The latest research shows if your child is having discipline problems, he or she may not be getting enough sleep. Too much sugar and over-stimulation, such as video games before bedtime, could affect your child's ability to sleep well, the station reported.
