In Vitro Drug Release Testing: Overview, Development and Validation01:10

In Vitro Drug Release Testing: Overview, Development and Validation

324
In vitro dissolution and drug release tests assess how quickly and how much of a drug is released from its dosage form into an aqueous medium under standardized laboratory conditions. These tests are essential tools in pharmaceutical development and quality assurance, offering insight into the drug's performance before clinical use.During formulation development, dissolution testing identifies incomplete or inconsistent drug release issues. It also supports decisions on selecting the optimal...

Reliability and Validity01:29

Reliability and Validity

13.8K
Reliability and validity are two important considerations that must be made with any type of data collection. Reliability refers to the ability to consistently produce a given result. In the context of psychological research, this would mean that any instruments or tools used to collect data do so in consistent, reproducible ways.

Data Validation01:03

Data Validation

6.4K
Data validation is an essential part of a comprehensive assessment. Validation is confirming or verifying and opening the door to gathering more assessment data as it clarifies vague or unclear data. The process of checking and verifying the collected information is called data validation. The primary purpose of data validation is to ensure data is as free from error, bias, and misinterpretation as possible.
Nursing assessment guides are generally based on holistic models rather than medical...

Data Validation01:15

Data Validation

732
Method validation is a crucial process in analytical chemistry designed to confirm that a given method consistently produces reliable and high-quality results. This process is essential when a method is applied to different sample matrices or when procedural modifications are made, ensuring that the results meet acceptable standards across various applications.
Key parameters for method validation include:

Body Temperature01:07

Body Temperature

1.4K
Body temperature reflects the equilibrium between heat production and heat loss within the body. Most heat is generated by metabolically active tissues, particularly the liver, heart, brain, kidneys, and endocrine organs. At rest, skeletal muscles contribute 20–30% of total heat production, but during vigorous exercise, this can increase up to 30–40 times.
The average body temperature is approximately 37°C (98.6°F) and typically ranges from 36.1–37.2°C...

Body Temperature01:25

Body Temperature

4.1K
The body's temperature, measured in degrees, is determined by the balance between heat production and dissipation to the surrounding environment. For instance, if exercising vigorously, the body will produce more heat, causing sweat and dissipating that heat. Despite extreme environmental conditions and physical exertion, the human temperature-control system maintains a constant core body temperature (the temperature of deep tissues, which are the tissues located beneath the skin and other...

Area of Science:

  • Psychiatry
  • Adolescent Psychology
  • Clinical Psychology

Background:

  • Body Dysmorphic Disorder (BDD) significantly impacts adolescent mental health.
  • Existing measures may not adequately capture the nuances of BDD symptoms in youth.
  • Early identification of BDD symptoms in adolescents is crucial for timely intervention.

Purpose of the Study:

  • To develop and psychometrically evaluate a new measure, the Multidimensional Youth Body Dysmorphic Inventory (MY BODI), for assessing BDD symptoms in adolescents.
  • To provide a reliable tool for identifying adolescents at risk for or experiencing BDD.
  • To align the assessment with DSM-5 diagnostic criteria for BDD.

Main Methods:

  • Development of the Multidimensional Youth Body Dysmorphic Inventory (MY BODI) with expert review.
  • Administration of the MY BODI and validation measures to 582 Australian secondary school students (ages 11-18).
  • Factor analysis to determine the measure's structure and convergent validity assessed through correlations with existing BDD symptom measures.

Main Results:

  • Factor analysis supported a 3-factor, 21-item structure for the MY BODI: Impairment/avoidance, Preoccupation/repetitive behaviours, and Insight/distress.
  • The MY BODI total and sub-scale scores demonstrated significant correlations with established measures of BDD symptoms (AAI, BDDQ-A), supporting convergent validity.
  • Preliminary validation indicates the MY BODI is a reliable self-report measure for BDD symptoms and severity in adolescents.

Conclusions:

  • The MY BODI is a psychometrically sound instrument for assessing BDD symptoms in adolescents.
  • This measure can aid clinicians and researchers in identifying youth who may benefit from BDD interventions.
  • The MY BODI contributes to the accurate assessment of BDD symptomology and severity in a vulnerable population.
