The major causes of mortality and morbidity among U.S. teenagers have shifted from infectious to behavioral etiologies.
 

Risky behaviors:

Negative health outcomes:


Risk-taking Behavior in Adolescents: The Paradigm
by Charles E. Irwin, Jr., Vivien Igra, Stephen Eyre, and Susan Millstein, UCSF
 

Two assumptions drive the research on risk-taking in adolescents:

1) teenagers engage in a series of "risky " behaviors and feel invulnerable to the consequences of these behaviors as compared to adults.

2) All risk-taking behaviors occurring through the second decade of life are driven by similar mechanisms and the behaviors themselves are similar.

For later discussion: Views that challenge the paradigm:
"Risk behavior, the dominant construct explaining adolescent morbidity and mortality, is inadequate because it assumes that all adolescents develop similarly when, in fact, gender, race, and socioeconomic status force different developmental patterns and health outcomes." p. 126 Beyond Risk Taking (FS140R course reader)
 

The paradigm of risk is explained using 3 approaches:
1. dispositional
2. ecological
3. biological
 

Why do we need to explain risk using a distinct model?
Because these models have implications for intervention and prevention programs.
 

1. Risk-taking as a dispositional trait:

The paradigm:


Tenets:


 

Version One: deviance is a function of a character deficit:

Implications for intervention:
Direct education and intervention programs at improving self-esteem, reducing depression, decreasing impulsivity, etc. (address the individual behavior trait).

Counter arguments to this view:

Version two: dispositional model: sensation-seeking


Implications for intervention?...
 

 2. Risk-taking from an ecological perspective:

The paradigm:

Tenets:


Implications for intervention:
Change the social context
Give teens tools to navigate their environment.

Example of an ecological model:
from M. Brofenbrenner: The ecology of human development. Experiments by Nature and Design.  1979.

An ecological paradigm for adolescents' social world:

1. Microsystem: proximal contexts, direct interaction


2. Exosystems: more distal social contexts


3. Macrosystems: the most distant social contexts


1. Microsystems:
risk research traditionally focuses on peers and parents

Peers
 


Research documents a correlation between a teen's behavior and that of her peers.

Counterpoint: Maybe adolescents who are inclined to take risks just choose peers who are similarly inclined (disposition).
 

Implications for intervention:

Parents:
Risky behavior correlates to two dimensions of parenting style:
1. level of demand that parents place on their adolescents  (demanding vs. not demanding)
2. the degree of emotional responsibility parents place on their adolescents (responsive vs. not responsive)

Research shows:

least risky behavior  ------------------------------------------------------->most risky behavior
demanding, responsive                          demanding, unresponsive                 undemanding, unresponsive
                                                            undemanding, responsive

Other Parental Influences:
 

- Adolescents from single parent families are more likely to engage in intercourse and less likely to use contraception than peers from two-parent families.
- Younger adolescents who take care of themselves after school have a 2-fold increase in substance use.
  - Higher rates of smoking among teens whose parents smoke.
- children of substance abusers more likely to use substances.
- counterpoint: could be genetic predisposition

Implications for Intervention:
Focus more education campaigns on parental behavior change.
 

2. Exosystems:
Media and community are common examples.

Media
- studies link tv violence and childhood aggression
- media portrayals of body image and dieting behaviors correlate to unhealthy eating behaviors

Community
- environment controls availability to risks
(cigarettes, alcohol, drugs)
- how well communities "link the achievement of future goals to the absence of risk-behaviors" influences risk behavior
- decreasing access to health-care and lack of insurance
 

Implications for intervention:


 3. Macrosystems: the impact of culture.

Risk-taking behavior rates vary in different cultural, economic, and political contexts

examples:
- despite similar ages of sexual debut, the US has the highest rates of adolescent childbearing and abortion in the developed world.

- Rates of contraceptive use vary significantly by religious affiliation

- Eating behaviors vary by culture
 

Little research has explored the meaning of risk taking in different cultures.

Implications for intervention:?...
 

 3. Risk-taking from a biological perspective:

The paradigm:


Examples

direct influences of biology:

Indirect influences of biology:                     **decrements in self-esteem and depression in adolescent girls


Implications for Intervention:

Example: Sexual Risk-Taking:

behaviors:

 negative health outcomes:


Facts:


Biopsychosocial factors:
Risk co-variation:
Adolescents who are having unsafe sex are also engaging in other risk behaviors.

Predictable Temporal sequence of risk behaviors:
In one study, 5x as many females initiated substance use prior to sexual activity than initiated sexual activity prior to substance use.

Racial/ethnic differences:
In another study, the number of risk behaviors (substance use, dangerous vehicle use, etc.) correlated with intention to become sexually active in white, but not black women (intended sexual debut only correlated with age).
 

Timing of Pubertal events:
earlier maturing girls:


Risk Perception
Egocentrism

Knowledge doesn't imply action:

 Challenging the paradigm: points for discussion...

"Risk behavior, the dominant construct explaining adolescent morbidity and mortality, is inadequate because it assumes that all adolescents develop similarly when, in fact, gender, race, and socioeconomic status force different developmental patterns and health outcomes." p. 126 Beyond Risk Taking
 

"The implication of much of our research is that sexual behavior during adolescence is "risky" behavior that is unacceptable.  Erhardt points out that many developed countries of the world view adolescent sexual activity as normal and acceptable.  Intervention strategies are directed at preventing unintended negative consequences such as pregnancy but these interventions are framed within  a context of acceptance of sexual expression in adolescence."  (most other developed countries have lower pregnancy rates than the US).  p. 131 adolescent sexual risk-taking
 

"When gender has been considered in prevention efforts, it is typically to enhance the self-esteem, self-efficacy or decision-making skills of girls as opposed to challenging the social contexts that proscribe sexual roles and expectations for women and that create or support an imbalance of power in their relationships with men." p. 127 Beyond Risk Taking
