Work Profile Inventory [WPI-12]

Description

The Work Profile Inventory (WPI-12) is a brief 12-item instrument designed to record essential characteristics of an individual’s job and subjective work experience.

It examines different aspects of the work environment, including job content and demands, autonomy, employment security, career-development opportunities, remuneration, relationships with colleagues, and managerial support.

The WPI-12 should not be confused with the Work Preference Inventory developed by Amabile and colleagues, which is a different instrument assessing intrinsic and extrinsic work motivation.

Thematic Areas

The 12 items may cover the following aspects of work:

• Satisfaction with job content.
• Working hours and employment organization.
• Autonomy and decision-making opportunities.
• Job demands and workload.
• Employment stability and security.
• Training and career-development opportunities.
• Satisfaction with remuneration.
• Relationships with colleagues.
• Managerial support and communication.
• Physical and organizational working conditions.
• Recognition of professional contributions.
• Overall evaluation of the work experience.

These areas should not automatically be treated as independent psychometric subscales without supporting factor-analytic evidence.

Aim

The WPI-12 aims to provide a concise assessment of how employees evaluate their position and working environment. It may be used:

• In job-satisfaction research.
• In organizational employee surveys.
• To identify areas requiring improvement.
• To evaluate organizational interventions.
• To investigate associations with occupational stress, burnout, and turnover intention.
• In human-resource management and career counseling.

The questionnaire is intended for descriptive and research assessment rather than clinical or individual diagnosis.

Data Analysis and Use

Frequencies, percentages, means, medians, and standard deviations may be calculated for each item. Item-level analysis is particularly useful because it can identify specific strengths and weaknesses within the working environment.

A total mean or sum score may be calculated if empirical analysis confirms that all 12 items measure a sufficiently coherent construct. Otherwise, results should be reported separately for the relevant thematic areas.

Statistical analysis may include:

• Internal-consistency assessment using Cronbach’s alpha or McDonald’s omega.
• Exploratory and confirmatory factor analysis.
• Correlations with job satisfaction and organizational commitment.
• Comparisons between occupational or demographic groups.
• Regression analysis predicting burnout or turnover intention.
• Comparisons before and after organizational interventions.

Scoring

Responses are recorded on a five-point Likert scale:

1. Not at all satisfied
2. Slightly satisfied
3. Moderately satisfied
4. Very satisfied
5. Completely satisfied

If all items are positively oriented and calculation of a total score is psychometrically justified, the theoretical range is 12–60. Higher values represent a more positive evaluation of the work experience.

No validated universal cut-off scores are available for classifying results as low, moderate, or high. Interpretation should therefore be based on the distribution of scores in the study sample or appropriate normative data.

Psychometric Documentation

The original text states that the instrument was developed in 2021 and reports a Cronbach’s alpha of .84 and a four-week test–retest coefficient of r = .76. However, these claims are not accompanied by an identifiable primary publication.

These values should not be presented as established psychometric properties without access to the relevant manual or scientific article. Before the WPI-12 is used in formal research, its content validity, factor structure, internal consistency, and relationships with established occupational measures should be examined.
