Summary
A refined Male Body Dissatisfaction Scale (MBDS) shows good psychometric properties in Brazilian and Portuguese students. A new scoring method improves accuracy in assessing male body image concerns.
Area of Science:
- Psychology
- Men's Health
- Psychometrics
Background:
- Body dissatisfaction is a growing concern among men.
- Existing scales may require validation or refinement for specific populations.
- Understanding male body image is crucial for mental health interventions.
Purpose of the Study:
- To evaluate the psychometric properties of the Male Body Dissatisfaction Scale (MBDS) in Brazilian and Portuguese university students.
- To develop a reduced, more robust version of the MBDS.
- To compare scoring methods and estimate the prevalence of male body dissatisfaction.
Main Methods:
- Confirmatory Factor Analysis (CFA) and multi-group analysis were used on data from 932 male students.
- The MBDS was refined by item exclusion and factor combination.
- Two methods for calculating body dissatisfaction scores were compared.
Main Results:
- A 12-item, 2-factor reduced MBDS model demonstrated adequate psychometric properties and cross-cultural invariance.
- The mean scoring method overestimated body dissatisfaction compared to a refined method.
- Prevalence rates for musculature and general appearance dissatisfaction were 11.2% and 5.3% respectively.
Conclusions:
- The reduced MBDS is a valid and reliable measure for assessing male body dissatisfaction in Brazilian and Portuguese student populations.
- The proposed scoring method offers a more accurate assessment of body dissatisfaction.
- Findings contribute to understanding and addressing male body image issues in higher education.

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.

01:09Clearance Models: Physiological Models
374
Drug clearance is a critical pharmacokinetic process involving the irreversible removal of drugs from the body through various organs over a specified time period. Physiological models are indispensable in determining organ-specific clearance, defined by the proportion of the drug eliminated per unit of time from the organ's blood volume.
The organ's clearance rate depends on the blood flow to the organ and the extraction ratio (E). The extraction ratio describes the organ's...

01:29Self-Discrepancy and Its Effects
362
Self-discrepancy theory explains how people compare their actual self to their ideal and ought selves and how mismatches between these self-guides can lead to emotional distress. Developed by E. Tory Higgins, the theory distinguishes among three components of self-concept: the actual self, the ideal self, and the ought self. These refer respectively to how individuals perceive themselves, how they aspire to be, and how they believe they are obligated to be. Emotional well-being, self-esteem,...

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...

2.5K
In classical mechanics, the two-body problem is one of the fundamental problems describing the motion of two interacting bodies under gravity or any other central force. When considering the motion of two bodies, one of the most important concepts is the reduced mass coordinates, a quantity that allows the two-body problem to be solved like a single-body problem. In these circumstances, it is assumed that a single body with reduced mass revolves around another body fixed in a position with an...
