Explore evolving conceptions of mind-body interactions in health research, focusing on stressors, pathogens, and internal processes. Delve into mediating models, individual differences, and health behaviors to understand outcomes. Discover how stress, behavior, and immunity influence overall health.

Stressor, pathogen Internal Process Health Outcome General Approaches to Health Research: Evolving conceptions of mind body Core construct: • General process: mediating models • What explains or accounts for a stress outcome effect • Basic theory development & testing • Individual differences: moderating models • Establish “boundary conditions” of effect or theory • Specify sub-population characteristics of an effect • Descriptive or theory-based: important to specify in advance for efficacy trials.
Other health behaviors: Diet, smoking… Mediating (and additive) models Environ-mental change, Adaptation syndrome Arousal, inflammation CHD • Ψ; distress, helplessness • Physiological: • Corticosteroids, pro-inflammatory cytokines, HPA activation • Lipids, insulin section & “metabolic syndrome” • Developmental changes • SES, culture, etc. • Infectious process • Individual stress
Health behavior: diet, exercise, smoking… Mediating (and additive) models Environ-mental change, Adaptation syndrome Psych. Process Arousal, inflammation CHD Self-efficacy Helplessness / depression Social resources
Negative health behavior Exposure to pathogens Arousal (coritco-steroids) • Basic mediating models in health behavior Immune function Stress Illness
Immune function Negative health behavior Stress Illness Socio-economic status Exposure to pathogens Structural & cultural barriers to health care • Health models with structural exogenous variables
Immune function Stress Interaction of stimulus by Ψ resources Health status “Optimism”, “hardiness”, social support Health behavior Basic moderating model
Direct effects of Ψ on health • Psychoimmunology; Adar’s work on affect, learning and immune function • Classical conditioning models: • immune status, tolerance, withdrawal, placebo effects • Etiology: arousal or affective effects on health • stress responses, arousal, and cardio-vascular health • bereavement and health: see House on social ties and mortality • affect (depression), self-concept, optimism, “sense of coherence” and immune function • Specific stressors and obesity Key issue: articulation of complex relations among CNS, ANS, Immune, and other systems.
Indirect effects of Ψ on health • “Health behaviors”: risks, protective behaviors [primary prevention] • Individual social / cognitive models of ... • Self-regulation (self-awareness, self-monitoring, self-efficacy) • Health information processing • Self-perception and decision making: • optimism (realistic or unrealistic) • readiness to (“stage of”) change • risk estimation (normative and non-normative) • change motivation, intrinsic – extrinsic motive • Affective state, • Alcohol & drug use • Social support
Indirect effects of Ψ on health; Health behaviors • Group-level variablescontrolling exposure, definition, and availability of (un)healthy behavior • social norms and/or socially structured rewards and punishments • gender, age, cultural group effects; “X”, smoking, etc. • models of (un)healthy behavior; processes of modeling influences • relations of individuals/groups with health “system”; providers, govt., schools, etc. • Cultural level variables • Economic / corporate incentives for (un)healthy behaviors • Main effects of socio-economic disparity • Main effects of ethnicity (“objective” status?)
Illness related behaviors2nd / 3rd prevention • Key steps: • Recognition of health problems • Definition of “disturbance” or problem • Treatment or help seeking • Recognition of a health threat • surveillance & early detection • basic health information approaches • Perceived vulnerability & susceptibility: Core precursor of virtually all health models • Weinstein: core Ψ variables (controllability) • Khaneman: Relative irrationality of risk perception • interpretation of symptoms or signs; implicit health models • Health belief model • Info about health threat • “Cues to action” • Health cognitions
Illness related behaviors2nd / 3rd prevention • Definition of “disturbance” or problem • interpretation of symptoms or signs; implicit health models • Health belief model • Info about health threat • “Cues to action” • Health cognitions • outcome expectancies for health / illness behavior • “adaptation level” and drifting criteria for diagnosis • Causal attribution models
Illness related behaviors2nd / 3rd prevention • Treatment or help seeking • Health belief / health barrier models: approach of treatment source • Individual and group differences in efficacy for behavior change • Coping models: instrumental v. affective coping • Socio-cultural variables in treatment response • adherence to treatments
