Transcript of TRA/TPB
Increase the proportion of adolescents (12-17) who perceive great risk associated with substance abuse Theory of Reasoned Action/Planned Behavior Key Determinants: Personality Includes:
perceptions and expectations associated with substance use
Constitutional factors: genetics (family history, addictive and thrill seeking) Key Determinants: Environment Correlates to perceived models of social influence
competing peer influences
perceived expectations Key Determinants : Sociological Children who experience constant family disruption and/or divorce
Cultural Aspects Major Impacts of Adolescent Substance Abuse Measuring the Prevalence In 2006:
48.2% of high school seniors reported lifetime use of any kind of illicit drug
25.1% reported drinking alcohol on three or more occasions within the past 30 days
20% of youth reported using an illegal drug before finishing the eighth grade -Consuming five or more alcoholic drinks at a single
occasion or twice a week
-Smoking marijuana once per month
-Using cocaine once per month Theory of Planned Behavior Common Uses for TRA and TPB Commons Uses: involve controllable behaviors that can be deliberate and are perceived as under the individual's control
diet and exercise Implementation of the Theory Theory of Reasoned Action Developed by Martin Fishbein and Icek Ajzen in 1975
Originated from the field of social psychology
Was a result of attitude research from the expectancy value models
Focuses on Behavior Intentions as main predictors:
Subjective Norms The TRA is regarded to have strong predictive utility but..
lacking in explaining behavior of those who have or feel like they lack control over their behaviors
Icek Ajzen added the TPB in 1985 as an extension of TRA
perceived control with facilitating and inhibiting factors Implementation of Theory Simple mail in surveys -to have an initial idea of behavioral intent
More in-depth interviews conducted afterward over various periods of
time to create specific interventions
Belief patterns may differ between various groups: age, race, gender
Group of 12-14 perceive substance use as a low risk
Group of 15-17 perceive substance use as a higher risk Implementing Theory Theory could also be used to identify if there are high-risk groups
Addressing key determinants: environmental, sociological, interpersonal A series of in-depth interviews conducted in middle and high schools
Could involve a variety of simple questions :
how likely do you think your friends have used drugs in the past 12 months?
how sure are you that you can say no to drugs if you really wanted to?
1 2 3 4 5 6 7 Implementing Theory Use findings to analyze and identify behavioral intentions to determine strategies:
Ex: Community Opinion Leader Model
Ex: Strengthening Families Program
Ex: Social Development Rationale This theory works well together with adolescent substance abuse because:
adolescents put substantial weight on subjective norms
data will help create specific and more persuasive interventions - addressing specific concerns and beliefs
strong starting point to learn about the population Questions inquiring about:
Their substance use/experience within the past year
How much parental monitoring they experience Limitations of Theory Unreliable Information: anonymity may help avoid this
Overlooks emotional variables: threat, fear
Assumes people are rational and make systematic decision: adolescents may not be completely rational In Conclusion Using this theory can provide detailed information about the population and can predict their behavioral intent
Predict intent Apply suitable interventions
TRA/TPB can help increase the perception of risk associated with drug use by creating more effective interventions through:
identifying their perceptions and beliefs
targeting high risk factors more effectively
knowing the audience 90% of adults with current substance disorders started
using before the age of 18 - half began before 15 Costly social, physical, mental and public health problems teen pregnancy Domestic Violence Motor Vehicle Crashes Suicide Individuals: experience developmental impairments, deficits in learning ability, and other mental health issues Family Life: problems in school, strained relationships, poor work performance Communities: disrupts neighborhoods, increased violence and crime National Drug Control Budget: 25.2 Billion Can be used as a predictive model for explaining human behavior voting behavior
environmental psychology This theory can be used as a strong stepping stone
for more effective interventions Requesting 25.6 Billion for 2013 2012 Implementing the TRA/TPB this way is about using the data to know the audience and how to best approach their perceptions Crime Use it to figure out what adolescent perceptions
and beliefs A problem with D.A.R.E. They didn't know what their audience's perceptions and beliefs were
so they ended up glamorizing and demonizing drugs They were counterproductive are to create specific interventions :took the approach of "just say no" Attitude, subjective norm and perceived control are independent of each other
The relative weights of each of the three factors will vary according to the specific behavior and/or population Implementing TRA/TPB
