Transcript Prediciting developmental change in risky driving.pptx

Risky driving
 Patterns of driving behavior that place
drivers at risk for mortality,
 Involve legal violations
 Do NOT involve alcohol or drug use.
Think About Risky Driving Practices
 Speeding
 Illegal turns
 Follow other vehicles too closely
Crashes & age

Motor vehicle crashes are generally resulted in death in US,

Common for people under 34,

Injuries are more than 40% among 16 to 19 years old

In this age group, the crash rate is at maximum level.
ALCOHOL


Older driver : alcohol ↑ driving ↓
Younger driver : alcohol ↑ driving↑
Risky Behaviour While Driving





Delinquent behavior
Problem drinking
Marjiuana use
Peer influence
As adolescents enter young adulthood;
More conventional
 Less involved in problem behaviors

How those risky behaviours can
diminish or discontinue?


With help of social roles/ responsibilities;

Marital Roles

Paretal Roles

Employment Roles
Self identication process as an ‘adult’
« expected to behave in the culturally prescribed manner»
Hypothesis

This study tries to examine;


Whether variation in risky driving can be explained by
variation in social role and psychosocial & behavioral
conventionality.
It is expected to find;
a. the occupancy of conventional adult roles and greater
psychosocial& behavioral conventionality should be related to less
involvement in risky driving
b. Also, result in a decline in risky driving behavior over time.
Method

Procedure;






A three wave annual mail survey
Including drink driving and risky driving
Consisting of young adults
A stratified random sample was used
Licensed drivers selected (18 to 25 yrs old)
Stratified by sex, age, area of the state and violation
status.
The Four Violation Status
1.
2.
3.
4.
No moving violations in the previous year
Three or more points for traffic violations
Conviction-suçlu- in previous year
Conviction in the past 3 months
Young Adult Driving Questionnaire

Consisting of,






A number of personality
Perceived social environment
Self-reported behavior measures
Competitive speed
Driving aggresion
After sending participation letters and getting signed
consent forms;



Questionnaire was sent to participants and completed
questionnaires was returned (wave 1)
A year later, a follow-up questionnaire was sent (wave 2)
Third questionnaire was mailed after a year again (wave 3)
a.Measurement of Driving Behaviors


Risky driving, drink driving and marijuana driving
In total, assessing by 28 items
o
Risky Driving;

o
Drink Driving;

o

Measured by 20 items
Measured by 5 items
Marjiuana Driving;
 Measured by 3 items
Asking frequency of engagement
b.Measurement of Social Role Statuses


Included 3 items
Whether the respondents;
Married
 Having children
 Working full time

c. Measurement of Conventionality

Psychosocial conventionality was measured by;
Two personality measures and
 Three perceived environment measures


Behavior conventionality was measured by;
 Deliquent
type behavior
 Church attendance
Results

It is found that;
Occupancy of young adult social roles and greater
conventionality = lower levels of risky behavior
Psychosocial Conventionality linked to less risky driving
Behavior Conventionality correlated with risky driving
Results (cont.)

A significant result in main hypothesis;
Change in social role statues and change in
psychosocial & behavioral conventionality = change in
risky behavior.
BUT change in behavioral conventionality has largest
impact.
What Happens Developmentally?

For the women;
 Changes

in social role statuses predicted maturing
For the men;
 Change
in behavioral conventionality predicted
maturing
Discussion


As participation in social roles, psychosocial and
behavioral conventionality , the involvement in
problem behaviors
As age increased from 18 to 25, a linear decline
occurs in levels of risky behaviors
Limitations



o
Analyses are based on self-reports
Measures of social role statues lack the known
reliability and validity
Sample is homogeneous
Future researches need to focus on and enhance
these limitations.
