The experience of stress can influence physical health. Suggest operational definitions for the variable of stress and the variable of physical Health.

Operational Definitions

1. Stress:

   • Definition: Stress can be operationally defined as a psychological and physical response to perceived challenges or threats.
   • Measurement: This can be measured using standardized instruments such as the Perceived Stress Scale (PSS), which assesses the level of stress based on subjective feelings of being overwhelmed, unable to cope, and feeling nervous or anxious over the past month. Biochemical markers such as cortisol levels measured through saliva or blood samples can also be used to quantify stress.

2. Physical Health:

   • Definition: Physical health can be operationally defined as a state of bodily well-being and the absence of disease.
   • Measurement: This can include several metrics such as:
     • Body Mass Index (BMI) to evaluate weight relative to height.
     • Frequency of doctor visits and reported medical conditions to identify any chronic illnesses.
     • Results from physical health assessments such as blood pressure, cholesterol levels, and fitness test outcomes (like VO2 max or endurance tests).

These operational definitions provide measurable ways to assess the variables of stress and physical health in research contexts.
