Self-Report Tests of Personality

Self-Report Tests of Personality

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.

Multimachine Stability

Multimachine Stability

Multimachine stability analysis is crucial for understanding the dynamics and stability of power systems with multiple synchronous machines. The objective is to solve the swing equations for a network of M machines connected to an N-bus power system.
In analyzing the system, the nodal equations represent the relationship between bus voltages, machine voltages, and machine currents. The nodal equation is given by:

Area of Science:

Occupational Health
Psychometrics
Workplace Safety

Background:

Work instability (WI) is a growing concern, impacting employee performance and increasing absenteeism.
Early identification of WI is crucial for mitigating its negative effects on individuals and organizations.

Purpose of the Study:

To develop and validate a screening questionnaire for measuring work instability.
The target population for this tool is manual workers.

Main Methods:

Qualitative interviews with manual workers informed item generation.
Rasch analysis was employed to refine the questionnaire and assess psychometric properties.
The draft survey was administered to a diverse group of manual workers.

Main Results:

110 potential items were generated from 17 interviews.
The final scale comprises 25 items, demonstrating good reliability (alpha = 0.86) and unidimensionality.
The scale met psychometric expectations with favorable item and person residual statistics.

Conclusions:

The Manual Work Instability Scale is a validated, psychometrically robust tool for assessing WI.
The scale integrates musculoskeletal and psychosocial factors relevant to manual occupations.
It shows potential for effectively screening and identifying work instability in physically demanding jobs.
