In a developmental stage marked by intense physical, emotional, and intellectual changes, it's no surprise that adolescence often causes confusion and upheaval for the parent as well as the young person. The transitional period from child to adult is a difficult time for most, and the complexity of the modern world can serve to complicate the process.

In a developmental stage marked by intense physical, emotional, and intellectual changes, it's no surprise that adolescence often causes confusion and upheaval for the parent as well as the young person. The transitional period from child to adult is a difficult time for most, and the complexity of the modern world can serve to complicate the process.

A vast array of often conflicting opinions, ideas and news are only a few clicks of the button away in this Information Age. All too often, violence and dangerous behaviors are given flattering and undeserved attentions by the media. Many parents are rightly concerned about the availability of drugs, alcohol and other harmful choices that their children are exposed to at this trying age.

Adolescent depression, drug or alcohol dependency, and other mental health issues in both teenagers and pre-teens seem to be increasingly prevalent problems. Independence is greatly sought after at this age, yet coping skills and judgment are still developing. This makes it difficult for parents to decide when their child's behavior is par for the course, or when they may benefit from the guidance of a mental health professional to resolve potentially serious issues.

Major events in the young person's life often trigger such problems. These can include relationship problems, the death of a loved one, divorce, serious injury to the adolescent themselves or a family member or friend, or a national tragedy. It is critical that parents pay attention to any changes in their child's behavior, especially during and following such events. Here are a few behaviors to watch for that may indicate a need to call on a professional:

1. Increased defensiveness and secrecy. While it is not uncommon for teens and preteens to desire extra privacy, if the young person starts locking his or her bedroom door at all times and takes more time than expected to answer it, this may warrant concern.

2. Taking money from a parent's purse or wallet without asking. While stealing itself is a major issue, the need for additional money could also point to a drug habit or other problem.

3. Unexpected or extreme mood swings, moving from elation to outbursts of anger that are disproportional to whatever triggered the anger.

4. Unexplained cuts on the body.

5. Being exceptionally defiant toward parents or other authority figures, frequently missing curfew, chronic lateness or lying about plans and locations.

6. A sudden change in friends, especially if the child doesn't bring new friends home so the parents can meet them. Coinciding changes in behavior, attitude and clothing preferences are additional reason for concern.

7. A lack of interest in things the teen or pre-teen used to enjoy, or a significant drop in grades.

These aren't the only warning signs, but they're a good starting place. Every child is different, and parents know their children better than anyone else. Some of these behaviors may be more "normal" for a given teen than others; the most important thing is for parents to remain sensitive to their adolescents' immediate worlds and be alert to any behavior changes. The bottom line is that parents should trust their gut and consult with a psychologist or other qualified mental health professional if they suspect a serious problem.

Keeping the lines of communication open is critical to fostering a healthy relationship at any age. A trained professional can greatly assist both parents and adolescents in improving communication skills and strengthening family bonds during this challenging phase.
