Case Study

Which measurement scale should the researcher select to align with their study's goals, and why? Explain how the selected scale operationally defines stress compared to the alternative option.

Case context: A researcher is studying stress among undergraduate students. They want to investigate how daily, minor annoyances (such as misplacing keys or worrying about body weight) accumulate and affect academic performance. The researcher is deciding between using a major life events checklist or the Hassles and Uplifts Scale.

Question: Which measurement scale should the researcher select to align with their study's goals, and why? Explain how the selected scale operationally defines stress compared to the alternative option.

Sample answer: The researcher should select the Hassles and Uplifts Scale. This is because the Hassles and Uplifts Scale is specifically designed to operationally define stress by evaluating the impact of minor, everyday irritations (daily stressors like misplacing items or worrying about weight). In contrast, the major life events checklist focuses on major life changes, which would fail to capture the daily micro-stressors the researcher is interested in studying.

Key points:

  • Selects the Hassles and Uplifts Scale as the appropriate measure.
  • Explains that the scale measures the impact of daily, minor stressors (irritations).
  • Provides examples of daily stressors such as misplacing items or worrying about weight.
  • Contrasts daily stressors with the major life changes assessed by other scales.

Rubric: The student must recommend the Hassles and Uplifts Scale, explain that it measures minor daily irritations (with examples like misplacing items or worrying about weight), and explain that major life events checklists measure major life changes instead of daily stressors.
