Scale Analysis

The Personal Values Inventory (PVI), also known as L’Inventaire des Valeurs Personnelles (SPV), is a psychometric assessment tool developed to study the core values that guide individuals’ behavior and decision-making. The scale is based on theories of social psychology and personality, aiming to explore the multidimensional nature of values.

Purpose

The main purpose of the PVI is to capture and rank an individual’s personal values and to examine their influence on personal, social, and professional choices. The tool is used for research in psychology and the social sciences, for personal development and career programs, as well as in clinical applications such as counseling and psychotherapy.

Description

The PVI assesses six core categories of values through a series of statements. These are:
Social Justice (4 items)
Freedom & Autonomy (3 items)
Security & Stability (5 items)
Personal Growth (4 items)
Solidarity & Cooperation (3 items)
Spirituality & Conceptual Inquiry (3 items)
Participants respond using a 5-point Likert scale (1 = “Strongly Disagree” to 5 = “Strongly Agree”), based on how representative each statement is of their personal values.

Sample

The PVI has been administered to adults aged 18+ from different social and cultural backgrounds, professionals such as educators and administrative staff, as well as groups with special needs, including individuals in transitional life phases.

Scoring Method

Each response is scored from 1 to 5. The mean scores for each value category are calculated to determine the individual’s personal hierarchy of values. The analysis may also include comparisons between groups or across different points in time, such as before and after an intervention.

Validity

The PVI has been validated through comparative studies with other value scales, such as the Schwartz’s Value Survey, confirming its construct and criterion validity.

Reliability

The scale demonstrates high internal consistency (Cronbach’s α > 0.85 for all subscales) and stability (test-retest reliability r = 0.82).
