Index-Description

The PGWBI-22 is a self-reported scale consisting of 22 questions that cover various aspects of psychological well-being. The questions are categorized into six dimensions:

Anxiety

Depressed mood

Self-control

Positive well-being

General health

Vitality

Responses are provided on a Likert scale, which allows the measurement of the degree to which an individual experiences positive or negative feelings in different situations. The total scores offer an indication of an individual’s overall psychological well-being.

Data Analysis and Usage

Data collected through the PGWBI-22 scale are analyzed to evaluate the mental and emotional state of individuals in various contexts, such as clinical psychology, health, and wellness. The primary analytical techniques include:

Reliability analysis, such as using Cronbach’s alpha, to measure the internal consistency of the scale.

Factor analysis to confirm the structure of the six dimensions.

Descriptive statistics to capture the level of well-being in a population.

Statistical analysis, such as analysis of variance (ANOVA) or regression, to study the relationships between the different dimensions of well-being and other psychological or social variables.

Purpose

The goal of the Psychological General Well-Being Index (PGWBI-22) is to provide an overall assessment of an individual’s psychological well-being. Specifically, the scale aims to:

Measure the positive and negative emotions that affect general well-being.

Assess levels of anxiety, depression, self-control, and positive well-being.

Study how various factors, such as social, environmental, or health variables, influence psychological well-being.

The scale can be used in clinical studies to evaluate the impact of therapeutic interventions or lifestyle changes on psychological well-being.

Calibration

The calibration of the PGWBI-22 scale involves the following stages:

Reliability analysis to check the consistency of responses in the six dimensions of the scale.

Confirmatory factor analysis to validate the theoretical structure of the dimensions.

Cross-validation in different populations to ensure that the scale is reliable and generalizable to various social and clinical settings.
