Adolescent Development Stage – Adolescence is one of the periods in human life. It is one of the transitional stages from childhood to adulthood. The adolescent phase is one of the crucial periods that must be accompanied and guided by adults.

The adolescent period itself is grouped into three stages, namely early adolescence, middle adolescence, and late adolescence. Before recognizing the stages of adolescence, it is better for Grameds to first understand the meaning and characteristics of adolescents.

According to the World Health Organization (WHO), adolescents are people in the age range of 10 to 19 years. Meanwhile, according to RI Health Regulations Number 25 of 2014, youth is defined as residents in the age range of 10-18 years and according to the Population and Family Planning Agency (BKKBN) the age range of adolescents is 10-24 years and unmarried.

Meanwhile, the Ministry of Health defines youth as a period of human life in which rapid physical, psychological and intellectual growth and development occurs. He has the characteristics of high curiosity, tends to dare to take risks from his actions without considering them carefully, and likes things that smell of adventure.

Meanwhile, according to Monks and Haditono, a teenager is someone who is in the age range of 12-21 years. Adolescence is also a transition from childhood to adulthood. Therefore, the mindset will change and proceed towards adulthood.
