This NS 1400 Test 2 2026/2027 Exam Questions and Answers study document provides an 11-page exam-focused review of social ecology, the Social Ecological Model (SEM), nutrition and food-choice determinants, childhood eating behavior, COM-B, and behavior-change principles. The material is organized as direct questions with answers, making it suitable for rapid Test 2 revision, concept recall, and practice with terminology used throughout NS 1400.
A central focus is the Social Ecological Model and the relationship between individuals and their environments. The document defines ecology and social ecology and examines the multiple levels at which health behavior can be understood, including intrapersonal/individual, interpersonal, institutional/organizational, community, and societal influences. It also discusses microsystems, mesosystems, exosystems, and macrosystems, emphasizing the interaction among the individual, environment, and behavior. Personal attributes such as values, attitudes, knowledge, experiences, beliefs, and social identity are considered alongside family, friends, coworkers, institutions, communities, cultural contexts, and public policies.
The nutrition section provides detailed review of the determinants of food choice and diet-related behavior. These are organized around biological predispositions, experiences with food, person-related determinants, and social and environmental determinants. Specific influences include taste, pleasure, hunger, fullness, sensory-specific satiety, food availability, cost, culture, family, personal beliefs, attitudes, values, emotions, knowledge, skills, social relationships, the built environment, and public policy. The material emphasizes that simply providing nutritional knowledge is not necessarily sufficient to produce lasting behavioral change.
The document also examines how food preferences and eating behaviors develop from childhood through adolescence. Topics include prenatal and early food experiences, physiological and psychological responses, learned and conditioned responses, food neophobia, picky eating, diminished self-regulation during middle childhood, and increasing food autonomy during adolescence. Social conditioning is explored through role modeling, parenting practices, parenting styles, mealtime practices, labeling foods as good or bad, and portion sizes. The material additionally considers childhood obesity and the influence of family, community, demographic, and broader societal characteristics.
Another major component is the COM-B Model of behavior change, which explains behavior through the interaction of Capability, Opportunity, and Motivation. Capability is divided into psychological and physical components, motivation into reflective and automatic processes, and opportunity into physical and social components. The document connects these concepts with personal, social, and environmental contexts and distinguishes information intended to motivate change from information intended to facilitate change.
The final section reviews the five stages of change: precontemplation, contemplation, preparation, action, and maintenance. Combined with SEM and COM-B, these concepts provide a structured framework for understanding why people adopt particular health and nutrition behaviors, what may prevent behavioral change, and how supportive social and physical environments can contribute to maintaining healthier behaviors over time.
