Doctors have expressed concern about young women drinking large amounts of soda and about their decreased consumption of milk ("Teenaged Girls, Carbonated Beverage Consumption, and Bone Fractures," Archives of Pediatric and Adolescent Medicine [2000]: \(610-613\) ). In parts (a)-(d), construct two questions that might be included in a survey of teenage girls. Each question should include possible responses from which the respondent can select. (Note: The questions as written are vague. Your task is to clarify the questions for use in a survey, not just to change the syntax!) a. How much "cola" beverage does the respondent consume? b. How much milk (and milk products) is consumed by the respondent? c. How physically active is the respondent? d. What is the respondent's history of bone fractures?

Step by step solution

01

Construct Question Regarding Cola Beverage Consumption

The question could be phrased as: 'How frequently do you consume cola or similar carbonated beverages?' Possible responses could be categorized based on consumption frequency, like: 'Never', 'Once a month', 'Once a week', 'Several times a week', 'Once a day', or 'Several times a day'.

02

Construct Question Regarding Milk Consumption

The question can be stated as: 'How frequently do you consume milk or milk products (e.g., cheese, yogurt)?' Responses can again be segregated based on frequency like: 'Never', 'Once a month', 'Once a week', 'Several times a week', 'Once a day', 'Several times a day'.

03

Construct Question Regarding Physical Activity

The question would refer to physical activity, such as: 'How often do you participate in physical activity that makes you sweat and breathe hard (e.g., running, basketball, etc.)?' Responses could be provided as: 'Never', 'Once or twice a month', 'Once a week', '2-3 times a week', '4-5 times a week', 'Everyday'.

04

Construct Question Regarding History of Bone Fractures

The question might be something along these lines: 'Have you ever had a bone fracture?' The responses to this can be simpler as: 'Yes' or 'No'. If 'Yes', then follow-up question can be: 'If yes, how many times?' with numeric answers

Key Concepts

These are the key concepts you need to understand to accurately answer the question.

Questionnaire Construction

Creating a questionnaire is a crucial step in survey design. It directly influences the quality of the data collected. A well-constructed questionnaire ensures that respondents can understand and answer the questions accurately. Here are several factors to consider in questionnaire construction:

• Clarity: Each question should be clear and concise, avoiding any ambiguity. This helps reduce misinterpretations and ensures consistent responses.
• Specificity: Be specific in your questions. For instance, instead of asking "How often do you drink cola?", specify the time frame to "How many times a week do you drink cola?"
• Response Options: Providing predefined responses can make it easier for respondents to answer and helps in quantifying the data. Options like "Never", "Once a month", etc., are examples of categorized responses.
• Logical Flow: Organize questions in a logical sequence that feels natural to the respondent. This can improve the overall flow and response rate.

By focusing on these elements, you can create an effective questionnaire that yields high-quality, reliable data.

Data Collection Methods

Data collection in surveys can be done using various methods, each with its advantages and limitations.
When deciding on a data collection method, some key points to consider include:

• Surveys: These can be administered online, by phone, or in person. Online surveys are cost-effective and time-efficient, while in-person ones can yield detailed insights.
• Interviews: Structured or semi-structured interviews provide more in-depth data but require more time and resources.

Regardless of the method chosen, it's important to ensure the data collection process maintains a high level of reliability and validity.
This involves training data collectors, ensuring questions are asked in a consistent manner, and minimizing any biases that may affect responses.

Health Surveys

Health surveys are essential tools used in public health research. They gather data on different health indicators, which can inform policy and health interventions.
When designing health surveys, consider the following:

• Target Population: Define who the survey is intended for. In this case, teenage girls are the focus due to concerns about their beverage and milk consumption habits.
• Relevant Topics: Select topics that directly relate to health outcomes, such as dietary habits, physical activity, and history of bone fractures. This ensures the data collected are actionable and valuable.
• Ethical Considerations: Ensure that participants are informed about the survey’s purpose, and their consent is obtained. Privacy and confidentiality should be prioritized to protect participants' personal health information.

Health surveys can lead to significant insights that shape future health strategies and promote healthier behaviors among target populations.
