Summary
Definitions for skin quality attributes lack consistency across studies. This inconsistency hinders treatment comparisons and may impact patient outcomes in aesthetic medicine.
Area of Science:
- Dermatology and Aesthetic Medicine
- Medical Literature Analysis
Background:
- Skin quality is a comprehensive term for skin's appearance, texture, and health.
- Assessing skin quality involves various objective and subjective measures.
Purpose of the Study:
- To evaluate the consistency of definitions for skin quality attributes.
- To assess treatment outcomes related to skin quality attributes.
Main Methods:
- Conducted two systematic reviews of literature from PubMed, MEDLINE, and Embase.
- Searched for articles and abstracts assessing skin quality using objective or subjective instruments.
- Performed a supplemental search for meta-analyses on treatment outcomes.
Main Results:
- Analyzed 903 studies with 4,668 observations, 87% of which were subjective.
- Identified significant inconsistencies in attribute definitions, with 7-17 different definitions per attribute.
- Found no clear consensus on the definition of skin quality attributes.
Conclusions:
- The aesthetic medicine literature lacks consensus on skin quality attribute definitions.
- This absence of standardized definitions impedes comparative analysis of treatments.
- Inconsistent definitions may influence physician recommendations and patient outcomes.

Behavior is a product of both the situation (e.g., cultural influences, social roles, and the presence of bystanders) and of the person (e.g., personality characteristics). Subfields of psychology tend to focus on one influence or behavior over others. Situationism is the view that our behavior and actions are determined by our immediate environment and surroundings. In contrast, dispositionism holds that our behavior is determined by internal factors (Heider, 1958).

12.7K
Sampling is a technique to select a portion (or subset) of the larger population and study that portion (the sample) to gain information about the population. Data are the result of sampling from a population. The sampling method ensures that samples are drawn without bias and accurately represent the population. Because measuring the entire population in a study is not practical, researchers use samples to represent the population of interest.

01:14Fundamental Attribution Error
13.7K
According to some social psychologists, people tend to overemphasize internal factors as explanations—or attributions—for the behavior of other people. They tend to assume that the behavior of another person is a trait of that person, and to underestimate the power of the situation on the behavior of others. They tend to fail to recognize when the behavior of another is due to situational variables, and thus to the person’s state. This erroneous assumption is...

In social interactions, individuals frequently seek to understand the motivations and causes behind others' behaviors. This fundamental aspect of social perception, known as attribution, plays a crucial role in shaping interpersonal relationships and guiding future actions. Attribution refers to the cognitive process through which people infer the reasons behind others' behaviors, allowing them to assess character traits, intentions, and situational influences.Attribution Theory and Its...

In statistics, several tools are used to interpret the data. Measures of central tendency represent the characteristics of the data, such as mean, median, and mode. Additionally, measures of variance like standard deviation and range are used to find the spread of data from the mean. Relative standing measures the distance between data locations. Commonly used measures of relative standings are percentile, z score, and quartiles.

Data are individual items of information obtained from a population or sample. Data may be classified as qualitative (categorical), quantitative continuous, or quantitative discrete. Because it is not practical to measure the entire population in a study, researchers use samples to represent the population. A random sample is a representative group from the population chosen by using a method that gives each individual in the population an equal chance of being included in the sample. Random...
