Comment on 'Measuring Machiavellianism with Mach V: a psychometric investigation'
Journal of Personality Assessment
|February 1, 1984
Summary
This study challenges criticisms of the Mach V scale, finding that the arguments do not support replacing this measure of Machiavellianism. The article questions the validity and reliability of the Mach V.
Area of Science:
- Psychological Measurement
- Social Psychology
Background:
- The Mach V scale is a widely used instrument for assessing Machiavellianism.
- A recent critique by Shea & Beatty (1983) questioned the reliability, format, and validity of the Mach V.
Discussion:
- The critique raised issues concerning meaningful versus statistical criteria in scale evaluation.
- Differing perspectives on bias and the independence of reliability and validity were also discussed.
Key Insights:
- While acknowledging potential construct validity issues with the Mach V, this analysis argues against the necessity of a new measure.
- The critique's arguments are deemed insufficient to warrant the abandonment of the Mach V.
Outlook:
- Further research may be needed to refine the construct validity of the Mach V.
- The debate highlights the complexities in evaluating psychological measurement tools.

Self-Discrepancy Theory
One influential perspective on what motivates people's behavior is detailed in Tory Higgin's self-discrepancy theory (Higgins, 1987). He proposed that people hold disagreeing internal representations of themselves that lead to different emotional states.
Measures of Intelligence
Psychologists measure intelligence by using standardized tests that produce a score known as the intelligence quotient or IQ. To understand IQ tests, it's important to recognize the key principles behind their construction: validity, reliability, and standardization.
Validity refers to how well a test measures what it claims to measure. An intelligence test should accurately assess intelligence rather than another characteristic, like anxiety. Criterion validity is one way to evaluate this; it...

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.
Self-Evaluation Maintenance Model
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. Central to this model is the notion that individuals have an inherent desire to preserve a favorable self-image, which is continuously shaped by interpersonal comparisons and...
Strategies of Self-Presentation III: Self-Monitoring
Self-monitoring is a central construct in understanding individual differences in self-presentation strategies across social contexts. It refers to how individuals observe, regulate, and control their expressive behavior and self-presentation following situational cues. Self-monitoring reflects a person's sensitivity to social appropriateness and willingness to adapt behavior to fit varying interpersonal demands.High vs. Low Self-Monitoring IndividualsIndividuals high in self-monitoring are...
Dark Triad and Person Perception
Person perception is influenced by both external behaviors and the observer’s internal characteristics, including personality traits. Individuals with dark personality traits, comprising psychopathy, Machiavellianism, and narcissism — collectively known as the dark triad – exhibit manipulative and exploitative tendencies in social contexts. These traits affect how they perceive others and how they are perceived.The Role of Dark Personality Traits in Person PerceptionBlack et al. (2014) explored...
