Questionnaire-Description

The PLQ-24 is a questionnaire consisting of 24 items related to key aspects of lifestyle. These questions are designed to assess specific health-related habits and behaviors, such as:

Diet: Frequency of healthy food consumption, balanced nutrition.

Physical activity: Levels of physical exercise, regular activity.

Stress management: Techniques and practices for reducing and coping with stress.

Sleep habits: Quality and duration of sleep.

Smoking and alcohol consumption: Frequency and amount of consumption.

The PLQ-24 provides an overall picture of health-related habits, helping health professionals and researchers understand how these behaviors affect well-being.

Data Analysis and Usage

Data from the PLQ-24 are collected through participants’ responses to a series of questions, typically scored on a Likert scale. The results offer a quantitative assessment of participants’ habits and behaviors in various lifestyle areas.

Analytical techniques applied include:

Descriptive statistics for calculating averages, frequencies, and percentages of various behaviors.

Reliability analysis, such as calculating Cronbach’s alpha, to estimate the internal consistency of the questionnaire.

Correlation and factor analysis to examine the relationships between different lifestyle dimensions and identify possible patterns.

The data can also be used to explore the impact of lifestyle habits on health and to develop intervention programs aimed at improving quality of life.

Purpose

The main goal of the Personal Lifestyle Questionnaire (PLQ-24) is to assess health-related behaviors and habits of an individual, providing insight into their lifestyle. In this way, the PLQ-24 helps:

Identify behaviors that can be improved to promote health.

Detect individuals who may be at risk for health problems due to unhealthy habits.

Provide a basis for developing intervention programs and evaluating their effectiveness.

Calibration

The calibration of the PLQ-24 includes:

Reliability analysis to ensure the questionnaire consistently measures the various lifestyle dimensions. Cronbach’s alpha is typically used to estimate internal consistency.

Factor analysis to examine the structure of the questionnaire and determine if its items group into distinct categories of behaviors.

Validation using data from different populations to ensure that the scale is appropriate and reliable for various groups.
