Summary
This study validated the seven-item Servant Leadership (SL) scale using Confirmatory Factor Analysis and Rasch analysis. Findings confirm its psychometric properties for measuring servant leadership behaviors in organizations.
Area of Science:
- Organizational Psychology
- Educational Leadership
Background:
- Servant leadership is increasingly recognized across diverse organizations.
- Existing scales for servant leadership require psychometric validation.
- Understanding servant leadership behaviors is crucial for organizational effectiveness.
Purpose of the Study:
- To psychometrically characterize the Servant Leadership (SL) scale.
- To validate the SL scale using Confirmatory Factor Analysis (CFA) and Rasch analysis.
- To provide a reliable measure for servant leadership behaviors.
Main Methods:
- Confirmatory Factor Analysis (CFA) was employed to assess the scale's structure.
- Rasch analysis was utilized for detailed item and scale evaluation.
- Data were collected from 461 teachers internationally.
Main Results:
- The one-factor structure of the SL scale was confirmed via CFA.
- Rasch analysis supported the scale's reliability, unidimensionality, and local independence.
- One item showed differential item functioning (DIF) favoring females; another item did not fit the Rasch model.
Conclusions:
- The seven-item SL scale demonstrates strong psychometric properties.
- The validated SL scale is suitable for measuring servant leadership.
- Further research may refine the scale by addressing identified item issues.

The Self-Evaluation Maintenance (SEM) model offers a psychological framework to understand how individuals’ self-esteem is influenced by the achievements of others, particularly those with whom they share close personal bonds. The SEM model operates when personal rather than social identity guides individuals.

Obedience to authority is classically demonstrated in a more famous series of social psychology experiments performed by Stanley Milgram. He was a social psychology professor at Yale who was influenced by the trial of Adolf Eichmann, a Nazi war criminal.

Often, psychologists develop surveys as a means of gathering data. Surveys are lists of questions to be answered by research participants, and can be delivered as paper-and-pencil questionnaires, administered electronically, or conducted verbally. Generally, the survey itself can be completed in a short time, and the ease of administering a survey makes it easy to collect data from a large number of people.

Self-report inventories are objective personality assessments that use multiple-choice items or numbered scales, typically ranging from 1 (strongly disagree) to 5 (strongly agree). They are often called Likert scales after Rensis Likert. These inventories are widely used due to their ease of administration and cost-effectiveness. One of the most prominent examples is the Minnesota Multiphasic Personality Inventory (MMPI), initially developed in the 1940s to assess abnormal personality traits.
