### Model Response Outline

#### 1. Introduction
- **Definition**: Define health-compromising behavior (actions that threaten or undermine physical/psychological health, such as smoking, alcohol abuse, or poor diet/overeating).
- **Focus**: Select one specific health-compromising behavior, such as **smoking/nicotine addiction**.
- **Cognitive Explanations**: Introduce the key cognitive frameworks to be discussed, such as **Cognitive Dissonance Theory** (Festinger, 1957) and **Outcome Expectancies / Cognitive Bias**.
- **Thesis**: Cognitive factors play an essential role in the initiation, maintenance, and rationalization of health-compromising behaviors, though they are best understood when integrated with biological and sociocultural factors.

#### 2. Explanation 1: Cognitive Dissonance Theory
- **Theoretical Framework**: Festinger (1957) proposed that when individuals hold conflicting cognitions (e.g., 'I smoke' and 'Smoking causes cancer'), they experience psychological discomfort (dissonance). To resolve this, they either change the behavior or change their beliefs/cognitions (rationalization).
- **Application**: Smokers often minimize the perceived risks of smoking, overestimate their personal immunity, or emphasize benefits (e.g., 'it relieves my stress') to resolve dissonance.
- **Supporting Study**: **McMaster and Lee (1991)**
- *Aim*: To investigate cognitive dissonance in smokers compared to non-smokers and ex-smokers.
- *Method*: Survey measuring knowledge of smoking risks, personal risk perception, and rationalizations.
- *Results*: Smokers acknowledged the general dangers of smoking but consistently underestimated their personal risk compared to average smokers. They also endorsed more rationalizations (e.g., 'I smoke light cigarettes, so it is safer') to justify their habit.
- *Link*: This supports the idea that cognitive dissonance leads to distorted risk perceptions, helping maintain health-compromising behavior.

#### 3. Explanation 2: Cognitive Expectancy Theory
- **Theoretical Framework**: Suggests that behavior is driven by the expectations of the outcomes of that behavior. Positive expectancies (e.g., 'drinking alcohol will make me confident and relaxed') lead to higher rates of initiation and maintenance of the behavior.
- **Supporting Study**: **Smith and Goldman (1994)** (or similar research on alcohol expectancies)
- *Aim*: To evaluate how expectancies influence adolescent drinking behavior.
- *Findings*: Positive outcome expectancies about alcohol's social and emotional benefits predicted subsequent alcohol consumption levels in adolescents, demonstrating that cognitive beliefs act as a precursor to physical behavior.

#### 4. Critical Evaluation (Discussion / Synthesis)
- **Methodological Issues**: Much of the research is correlational, making it difficult to establish a causal relationship. Do expectancies cause the behavior, or does the behavior shape the expectancies (bidirectional ambiguity)? Self-report measures are susceptible to social desirability and memory bias.
- **Strengths**: Cognitive theories explain why individuals in identical environments make different health choices. They have high practical application in therapy—specifically Cognitive Behavioral Therapy (CBT), which targets and restructures faulty beliefs and irrational rationalizations.
- **Limitations**: Cognitive explanations can be reductionist if they ignore biological factors (such as physical nicotine dependence, genetic predisposition to addiction, and dopamine pathway activation) and sociocultural factors (such as peer pressure and socioeconomic status).

#### 5. Conclusion
- Conclude by summarizing that while cognitive models like cognitive dissonance and expectancy theories provide valuable insight into how individuals justify and sustain unhealthy choices, a holistic biopsychosocial model is required to fully address health-compromising behaviors.

### Assessment Criteria Breakdown (Max 22 Marks)

#### Criterion A: Focus on the question (2 marks)
- **2 marks**: The essay is consistently focused on the question, clearly addressing cognitive explanations of one specific health-compromising behavior throughout.
- **1 mark**: The essay addresses the question but fluctuates in focus or discusses multiple behaviors without a clear focal point.
- **0 marks**: The response is completely irrelevant to the prompt.

#### Criterion B: Knowledge and understanding (6 marks)
- **5-6 marks**: Detailed and accurate knowledge and understanding of cognitive explanations (e.g., cognitive dissonance, expectancies) and how they explain health-compromising behaviors are demonstrated.
- **3-4 marks**: Relevant knowledge is demonstrated but contains minor inaccuracies, omissions, or lacks depth in theoretical concepts.
- **1-2 marks**: Minimal or superficial knowledge of cognitive theories in health psychology is present.

#### Criterion C: Use of research to support knowledge (6 marks)
- **5-6 marks**: Relevant psychological research (e.g., McMaster and Lee, 1991; Smith and Goldman, 1994) is introduced, described accurately, and effectively used to support the cognitive explanations.
- **3-4 marks**: Relevant research is used, but there are omissions in details (e.g., aims, methods, or findings) or the link between the study and the cognitive explanation is weak.
- **1-2 marks**: Research is either absent, highly inaccurate, or descriptive with no clear link to the prompt.

#### Criterion D: Critical thinking (6 marks)
- **5-6 marks**: The response exhibits well-developed critical evaluation. It evaluates the cognitive explanations and research studies by highlighting strengths, limitations, methodological issues (e.g., self-reports, correlational design), and alternative approaches (e.g., biological/biopsychosocial model).
- **3-4 marks**: Critical evaluation is present but limited, superficial, or tends to rely on generic evaluation points without deep connection to the topic.
- **1-2 marks**: Critical thinking is absent or extremely limited.

#### Criterion E: Clarity and organization (2 marks)
- **2 marks**: The essay is well-structured, logical, and easy to follow. Psychological terminology is used effectively.
- **1 mark**: There is some structure, but the organization is disorganized, or terminology is used incorrectly.
- **0 marks**: The response lacks structure and is difficult to comprehend.
