Lecture 25 Problems
PROBLEMS
• In general, adolescents do not develop serious psychological or
social problems
• For those that do have problems:
– Most problems reflect transitory experimentation, not enduring
patterns of bad behavior & most don’t persist into adulthood
– Not all problems begin in adolescence—issues were already
evident but becomes bigger during adolescent
– Problems during adolescence are not caused by biological
changes(not hormonal changes)
– Status offenses
• Offense according to the law but stops being a
problem when you are over 18
• Like underage drinking
TYPES OF PROBLEMS
• Internalizing disorders – problems are turned inward
– Comorbidity among internalizing problems
– Different expression of same underlying bio prob
– Temperament factor
– Underlying factor could be Negative Affectivity
– Negative Affectivity = How easily someone becomes distressed
• Externalizing disorders – problems are turned outward
– Comorbidity
– Substance abuse problems often with externalizing problems

Juvenile offending
• Delinquency in underage = criminal offenses in adults
• Index crimes (violent/property)
• Violent crimes
• Increase in frequency between the preadolescent and
adolescent years
• Peak during high school then declines in young adulthood (the
age-crime curve)
• Status offenses – behaviors that are not against the law for adults
(truancy, running away, drinking)
• Crime rates higher during adolescent (16-21 yrs) then declines with
age
• Same across world and history
• Antisocial behavior takes the form of:
• Authority conflicts – ODD
• Covert antisocial behavior – hidden
• Ex: lie/ hide/ stealing/ shoplifting/ vandalism/ burglarizing/
fraud
• Overt antisocial behavior- fighting
• Being violent face to face
• Attacking people with weapons- murder
