The effects of being a latchkey child differ with age. Loneliness, boredom and fear are most common for those younger than ten years of age. In the early teens, there is a greater susceptibility to peer pressure, potentially resulting in such behavior as alcohol abuse, drug abuse, sexual promiscuity and smoking. The behaviors might stem from "unspent energy, peer pressure to misbehave, or hostility because of the lack of appropriate adult attention". However, some children experience other effects, such as an early development of self-reliance, adaptation to difficult situations, and a desire to contribute to a visible need in the household.
