There are so many things that can affect a child's success, including socioeconomic status, the environment they live in, and their parents’ education level.
Though it can be difficult for studies to determine what parenting techniques are ideal since researchers usually don't follow families long-term, there are certain parental behaviors that scientists have found could be linked to problems in children, like depression and anxiety, later in life.
1. They don't encourage their kids to be independent.

In 1997, a study at Vanderbilt University found that parents who psychologically controlled their children created to a host of negative outcomes for kids, including low self-confidence and self-reliance.
Encouraging children — especially teens — to be independent can be a good thing, especially in enhancing their ability to resolve conflict and have interpersonal relationships, according to this study in the Journal of Research on Adolescence.
Additionally, this study found evidence that more independence could lead to an increase in teens' ability to resist peer pressure.
2. They yell at their kids — a lot.
A 2013 study out of the University of Pittsburgh found evidence that harsh verbal discipline like shouting, cursing, or using insults may be detrimental to kids' well-being in the long-term.
The two-year study also found that harsh verbal discipline had comparable negative effects — such as behavioral problems and depressive symptoms — to studies that focused on physical discipline.
“It's a tough call for parents because it goes both ways: problem behaviors from children create the desire to give harsh verbal discipline, but that discipline may push adolescents toward those same problem behaviors," the study's author said in a press release.
3. They're 'helicopter parents.'

While being an involved parent is a good thing, being a "helicopter parent," or a parent who is over-controlling, could result in higher levels of anxiety and depression in children.
"Students who reported having over-controlling parents reported significantly higher levels of depression and less satisfaction with life," researchers wrote in a 2013 study of nearly 300 college students in the Journal of Child and Family Studies.
It's one in a number of other studies that point to a possible connection between over-controlling parents and depression in college-aged young adults, including a 2011 study from the University of Tennessee at Chattanooga.
The researchers found that children with so-called "helicopter parents" were less open to new ideas, more self-conscious, and happened to use more pain pills recreationally.
4. They let their children decide their bed times.

Researchers from the UK found a link between irregular bedtimes and worsening behavior scores, which included hyperactivity, conduct problems, peer issues, and emotional difficulties.
Plus, irregular bedtimes could affect the developing brain.
"We know that early child development has profound influences on health and wellbeing across the life course. It follows that disruptions to sleep, especially if they occur at key times in development, could have important lifelong impacts on health," one of the study's authors, Yvonne Kelly, told Medical News Daily.
5. They let them watch TV when they're really young.

Though screen time has been a parental boogieman for decades, it seems there may be cause for concern.
A 2007 study published in The Journal of Pediatrics indicates that heavy television viewing for kids before three years of age affects vocabulary, participation, and made them more likely to bully other classmates when they enter kindergarten.
Heavy television usage has also been associated with attention problems as well as impaired reading and math proficiency.
Some studies have indicated that educational programs like "Sesame Street" or "Barney" are beneficial, but only for kids between two-and-a-half and five years old.
