Developmental phases
Slide 5-

Drug use is a developmental problem
Slide 6-

Developmental Phases Each stage of development, from infancy to early adulthood, is associated with a certain expected range of: intellectual ability language development cognitive, emotional and psychological functioning social competency skills Each needs attention to prevent the onset of drug use and dependence!!!
Slide 7-

Infancy
Slide 8-

Infancy Protective Traits, Skill Sets & Experiences: Responsiveness to the environment and caregivers’ interactions Caregivers who are responsive Surroundings that provide stimulation Learning how to be effective in having needs met Easy to soothe Not temperamental
Slide 9-

Early Childhood Factors Predictive of Later Social Competence: Language Cooperation Control of emotions Collective conscience Social and emotional skills (including perception of others’ emotions) Problem solving
Slide 10-

Milestones in Middle Childhood Emerging Executive Cognitive and Emotional Regulatory Functions: Maintaining attention Controlling emotions Social inclusivity Effective communication Receptivity to others Accurate perception of emotion in self and others
Slide 11-

Adolescence
Slide 12-

Adolescence Integral to self-regulation of emotion and behavior to prepare for adulthood: Social and emotional skills to establish stable relationships Sensitivity to feelings & needs of others Conflict resolution Prosocial skills Impulse control Decision making Problem solving

Even under normal conditions, the adolescent prefrontal cortex is not completely connected! Under Construction
Slide 15-

The “Imbalanced” Adolescent Brain Emotional responses are heightened Cognitive controls are immature Double Jeopardy!
Slide 16-

Executive cognitive function (ECF)A multi stage process
Slide 17-

Executive cognitive function (ECF)A multi stage process Developmental milestones reflect extent to which executive cognitive functions (ECFs) are maturing: They begin to form in early childhood and coalesce in late 20s. Based on development of the prefrontal cortex (PFC) that regulates regions responsible for processing emotion and reacting to stress (limbic system). Poor PFC control over limbic regions increase rewarding aspects of novelty seeking behaviors and addictive properties of drugs ECF integrity thus forms the basis for behavioral self-regulation.
Slide 18-

Significance of Developmental Phases for Prevention Behavioral problems underlying drug use all involve poor self-regulation. Social and physical environmental risk factors impact on executive-cognitive functions and emotion regulation. This impact depends on: Personal characteristics (e.g., depression, high activity levels, attention deficit disorder, etc.) which develop and evolve over time. Developmental period of exposure to risk factors. Not only adolescence!!! Developmental phase determines what program components and policies will be understandable and executable.
Slide 19-

Interaction of Personal Characteristics and the Micro- and Macro-Level Environments
Slide 20-

Primary Developmental Outcomes and their Environmental and Personal Influences
Slide 21-

Types of Influences on Behavior Personal Characteristics Neurological delays Stress reactivity Mental health and personality traits Micro-Level Factors Family School Peer Macro-Level Factors Income and resources Social environment Physical environment
Slide 22-

Neurological Deficits and Delays When the prefrontal cortex is slow to develop or not functioning properly: Inability to accurately interpret social cues Negative emotions dominate Impulsivity & low self control Insensitivity to consequence But…heightened sensitivity to rewards Sensation-seeking Poor stress reactivity Inattention
Slide 23-

Implications of Delays in Brain Development for Behavior The signs of poor self-regulation due to deficits and delays vary as a function of developmental stage: In younger children: language delays, poor school readiness and academic achievement, conduct problems, negative affect, insensitivity to consequences, and impulsivity. In late childhood and early adolescence: aggression, sensation-seeking, delinquency, negative affect, and poor decision making and coping skills. Detrimental environmental conditions (stress, maltreatment, poor nutrition, and other adversities) further compromise brain development and increase risk for drug use and addiction.
Slide 24-

Stress Exposures and Reactivity Stress compromises development of brain systems that are at the basis of social, behavioral, cognitive, and emotional functioning Stress disrupts hormones that regulate these functions
Slide 25-

Stress, drug use and addiction
Slide 26-

Stress, drug use and addiction Stress activates the same brain [reward] systems responsible for the positive reinforcing effect of drugs It may damage and cause further delays to the brain & ECFs It increases physiological sensitivity to drugs It increases desire to improve mood with drugs after exposure to stress Stress more strongly predicts drug use when there is a psychiatric disorder, poor parenting, family dysfunction, and adverse neighborhood characteristics. Stress, lack of social supports, and poor coping skills predict early onset and escalation of drug use, relapse, and treatment resistance.
Slide 27-

Sex Differences in Stress Responses Girls report more negative life events during adolescence than boys and are more adversely affected by them, especially interpersonal stressors. Depression and anxiety are more common in girls starting in early adolescence. Interestingly, Post-Traumatic Stress Disorder (PTSD) often precedes drug use in girls, but occurs more often after drug use in boys. Girls are at increased risk for substance abuse when exposed to the stressors of family violence and alcoholism. Preventive Implications: Sex differences should be taken into account in identifying factors that contribute to drug use and in the development of a prevention or treatment plan.
Slide 28-

Mental Health Problems (1/2) Mental Health Disorders are strongly linked to drug use and dependence. Internalizing Disorders (PTSD, Depression, Anxiety disorders, Bipolar disorder) Brain responses are heightened in response to stress. Tendency to self-medicate the anxiety & depression this process causes.
Slide 29-

Mental Health Problems (2/2) Externalizing Disorders (Conduct Disorder, Attention Deficit Hyperactivity Disorder, Oppositional Defiant Disorder, Antisocial Personality Disorder) Low level of arousal in these disorders is related to an insensitivity to consequences and a need for more stimulation. Heightens risk for continued drug use to relieve symptoms Tend to be resistant to substance abuse treatment Exacerbates stress reactivity problems
Slide 30-

Personality & Temperament A difficult temperament and certain personality characteristics are consistently related to heightened risk for drug use. Impulsivity Aggressiveness Sensation or novelty-seeking Negative affect Impaired judgment High activity level Risk taking tendencies Lack of regard for negative consequences Lack of pain avoidance responses Abnormal levels of arousal in response to stress.
Slide 31-

Importance of Personality in Adolescence Normal adolescence is characterized by greater reward anticipation, sensitivity, and sensation seeking—particularly social rewards (e.g., peer regard, gains in social status). It follows that adolescence is the period during which drug use onset is most common. And, therefore, that adolescents with especially high levels of any combination of these traits are at heightened risk. Preventive Implications: These traits can be redirected through psychosocial means to decrease risk for drug use. Prevention programs must be designed to specifically redirect this developmental track.
Slide 32-

Interaction of Personal Characteristics and the Micro- and Macro-Level Environments Personal Characteristics Micro-Level Environments Macro-Level Environments Beliefs Attitudes Behaviors
Slide 33-

Micro-Level Influences: family, school, peers
Slide 34-

Micro-Level Influence: Parents and Family The home environment is the single most profound influence on every aspect of child development Effects of poor parenting are longstanding Parents need to instill social and emotional regulatory skills early in life to resist substance use Parenting and family continue to be important through adolescence when youth have more autonomy and opportunities for risky behaviors Preventive Implications: Intervening at the parent level is crucial to improve child outcomes.
Slide 35-

Parenting Styles That Interfere with Healthy Child Development Negative influences Insecure attachment Lack of warmth & affection Lack of supervision & monitoring Poor disciplinary tactics Inconsistent Reinforcements for negative behaviors Severely negative influences Harsh Restrictive Domestic violence Abuse & neglect Hostile High in conflict Emotionally triggered Caregivers who are not responsive
Slide 36-

Links to Aggressive Behavior & drug use Children exposed to stress and conflict in the home are more likely to: Become more behaviorally and emotionally maladjusted Have high levels of mental and physical health issues Manifest high levels of aggressive behavior, the strongest predictor of later drug use and other risk behaviors Characteristics of the family (e.g., cohesion, supportive, communicative) influence the ability to develop resiliency skills. Preventive Implications for Exposed Children: Training in parent skills, relieving the stressors and mental health problems of caregivers, and trauma prevention and treatment strategies.
Slide 37-

Micro-level influences: school and education Lack of education or poorly equipped schools and teachers: Slows child development, particularly cognitive functioning Interferes with development of self-regulatory and social skills Increases levels of stress, perceptions of inadequacy and failure Related to lack of parental involvement in schooling Compromises attachment to school (a resiliency factor) Prevents us from availing ourselves of opportunities for early detection, intervention and treatment Compromises children’s ability to succeed in life Preventive Implications: Quality of schools, its teachers, curriculum, and students’ social networks in school are major socializing influences to be taken advantage of.
Slide 38-

Micro level influences: peers
Slide 39-

Micro-level influence: peers (1/2) Peer relationships are influential socializing experiences that affect attitudes, skills, and “normative” behaviors: Can supersede parent influences. Presence of peers undermines executive decision making. Time spent in unstructured settings (e.g., on street) heightens this effect.
Slide 40-

Micro-level influence: peers (2/2) Social networking technology removes parents from interactions with the child, further reducing their influence Preventive Implications: Parents’ use of rules to monitor adolescents’ activities and encouraging healthy outside-the-home activities are critical to reducing negative peer influence.
Slide 41-

Sex differences in peer influences
Slide 42-

Sex differences in peer influences Girls are influenced by peers differently than boys: More likely to use drugs if friends & partners are using or introduces drugs to them. Concerns about peer approval, depression and body image – all interrelated – increase susceptibility to drug use in girls. Early onset of puberty increases risk for risky behaviors. Tend to date at younger ages and be with older risk taking males More conflict with parents around issues like dating, selection of friends, and shifting behavioral expectations. Higher levels of conduct problems Living in a poor community exacerbates the effect of peers on drug use risk for both sexes.
Slide 43-

Macro level influences:poverty, social and physical environment
Slide 44-

Macro-level influences of poverty (1/2)Societal level Affects the quality of the environment Limits choices and opportunities for adults to help children Places a strain on social systems and supports Increases conflict Has adverse effects on parent and child health Breaks down cooperation among residents and between community organizations Consequences for children: Difficult to teach children effective social skills they will need to interact with peers and other adults Poor children are much more likely to grow up to be poor adults and raise children who suffer the same problems
Slide 45-

Macro-level influences of poverty (1/2)Harming individual child and youth development Increases stress in caregivers Less able to attend to basic and emotional needs of the child Child maltreatment and neglect is more common Reduces ability to invest in learning & educational opportunities in school and day care Compromises ability to be involved, patient, responsive and nurturing parents to their children throughout development. The caregiving environment is more disorganized and lacking in appropriate stimulation and support Creates conditions that are stressful for children Interferes with growth, ability to respond adaptively to stress, development of psychological health and self-regulatory skills
Slide 46-

The Good News! High quality parenting has potential to mitigate the effects of poverty, particularly for girls! This is one important target for preventive interventions!
Slide 47-

Implications for Impoverished Children Prevention strategies to develop skills to improve chances of success in school and life: Increase availability of badly-needed services Political and health care involvement Increase efforts to reduce poverty and to avoid detrimental consequences on child development Particularly with respect to learning the skills needed to escape poverty and succeed in life Facilitate the implementation of comprehensive programs Enact programs to alleviate the sources of poverty.
Slide 48-

Macro-Level Influences of the Social Environment The social environment of the larger community influences drug use risk through: Shaping social norms Enforcing patterns of social control Influencing beliefs about the risks and consequences of using drugs Effecting stress responses Critical to maintain neighborhood viability and cohesiveness Peers during adolescence are especially influential
Slide 49-

Social cohesion Social Cohesion = attachment to and satisfaction with the neighborhood Involves trust and support for one another in a community Maintains norms for positive social behavior Associated with lower drug use and lower drug-related mortality
Slide 50-

Discrimination Discrimination and social exclusion have profound negative effects: Physical and mental health disorders, including drug use and dependence Poor educational attainment & lower levels of employment Restricted access to services and social supports Effects are compounded for immigrants.
Slide 51-

Political instability Disrupts basic services; housing, sanitation, water, & health care Orphaned, living alone on the street, or forced to be soldiers Violence, unhealthy conditions, traumatized, and victimized Deficits and delays in numerous functional domains Preventive solutions could be found in governments that: Protect child welfare Prohibit them from entering war zones Meet rehabilitation needs Provide shelter, food and clean water Provide psychosocial support to overcome damage
Slide 52-

Macro influences of the physical environment
Slide 53-

Many aspects of the physical environment harm child development Affects social relations, crime and drug use: Decayed and abandoned buildings Ready access to alcohol and drugs Neighborhood disorder: vandalism, graffiti, noise, and dirt Urbanization of the area Neighborhood deprivation Neurotoxins: lead, cadmium, mercury, arsenic, second-hand smoke Prenatal exposure to drugs, alcohol, toxins, and nicotine Negative [pro-drug] media messages
Slide 54-

Some conclusions
Slide 55-

Implications of the researchfor drug prevention (1/2) Behavioral problems underlying drug use all involve poor self-regulation and are preventable if appropriately addressed. Evidence-based programs are designed according to information on etiology Programs that target mechanisms underlying self regulation and, in turn, drug use is the key to prevention Vast brain plasticity in childhood means there is great potential to improve functioning Targeting socio-emotional and cognitive skills can redirect and normalize the developmental pathway.
Slide 56-

Implications of the researchfor drug prevention (2/2) Appropriately targeted interventions may be particularly impactful for disadvantaged children who experience social ills. A comprehensive evidence-based set of solutions to prevent drug use operates to enhance multiple domains of brain function.
Slide 57-

Take away message 1The earlier, the better The earlier the intervention, the more effectively we can… Redirect behavioral pathways Increase resiliency Reduce exposure to the potentially long-term adverse effects of the above etiological conditions, including the early use of drugs itself.
Slide 58-

Take away message 2Prevention is timeless Even very young children can manifest early signs of future mental, emotional, and behavioral disorders that increase risk for later drug use. A great deal is known about how to prevent, monitor, and treat these problems to ensure children reach their highest potential. In all cases and ages, an enriched environment, external supports, and high quality education is essential.
Slide 59-

Take away message 3It’s never too late! Many mental health, emotional, and behavioral problems stem from impulsive, sensation-seeking activities in adolescence Problems important to monitor and prevent include: Early alcohol, tobacco, and other drug use Violent and delinquent behaviors Depression and suicide Risky sexual behaviors In adulthood, influences persist and require address to prevent further escalation of use, addiction and relapse. Fortunately, there is tremendous brain plasticity and maturation of functions through adolescence and early adulthood Provides a solid window of opportunity to improve outcomes
