Insights

The Cincinnati Fecal Incontinence Scale (CINCY-FIS) is a new, reliable tool to measure quality of life and stress in children with fecal incontinence. It is sensitive to changes, making it useful for clinical and research settings.

Area of Science:

  • Pediatric Gastroenterology
  • Psychometrics
  • Quality of Life Research

Background:

  • Fecal incontinence is common in children and significantly impacts their psychosocial well-being and family dynamics.
  • Existing measures may not fully capture the multifaceted impacts of pediatric fecal incontinence.
  • There is a need for a validated instrument to assess quality of life and caregiver burden.

Purpose of the Study:

  • To develop and psychometrically validate the Cincinnati Fecal Incontinence Scale (CINCY-FIS).
  • To assess the quality of life for children experiencing fecal incontinence.
  • To evaluate the impact of pediatric fecal incontinence on caregivers and parenting stress.

Main Methods:

  • Item generation involved literature review, expert consensus, and pilot testing with 8 families.
  • Confirmatory factor analysis was performed on data from 222 caregivers to reduce items to a final 18-item scale.
  • Validity (convergent and criterion) and reliability (internal consistency, test-retest) were rigorously assessed.

Main Results:

  • A five-factor first-order structure with two higher-order factors showed a good fit to the data.
  • The CINCY-FIS demonstrated established convergent and criterion validity across all scales.
  • High reliability was confirmed through internal consistency and test-retest measures.

Conclusions:

  • The CINCY-FIS is a psychometrically sound and dependable tool for assessing pediatric fecal incontinence.
  • It effectively measures disease-specific quality of life and parenting stress in this population.
  • The scale's sensitivity to change makes it valuable for both clinical practice and research applications.

Half-life of a Reaction02:42

Half-life of a Reaction

The half-life of a reaction (t1/2) is the time required for one-half of a given amount of reactant to be consumed. In each succeeding half-life, half of the remaining concentration of the reactant is consumed. For example, during the decomposition of hydrogen peroxide, during the first half-life (from 0.00 hours to 6.00 hours), the concentration of H2O2 decreases from 1.000 M to 0.500 M. During the second half-life (from 6.00 hours to 12.00 hours), the concentration decreases from 0.500 M to...

Characteristics of Life

Biology is a natural science that studies life and living organisms, including their structure, function, development, interactions, evolution, distribution, and taxonomy. The field's scope is extensive and divided into several specialized disciplines, such as anatomy, physiology, ethology, genetics, and many more. All living things share a few key traits, including cellular organization, heritable genetic material and the ability to adapt/evolve, metabolism to regulate energy needs, the...

Reliability and Validity01:29

Reliability and Validity

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.

Initiation of Translation02:33

Initiation of Translation

Initiating translation is complex because it involves multiple molecules. Initiator tRNA, ribosomal subunits, and eukaryotic initiation factors (eIFs) are all required to assemble on the initiation codon of mRNA. This process consists of several steps that are mediated by different eIFs.
First, the initiator tRNA must be selected from the pool of elongator tRNAs by eukaryotic initiation factor 2 (eIF2). The initiator tRNA (Met-tRNAi) has conserved sequence elements including modified bases at...

The Angiosperm Life Cycle02:39

The Angiosperm Life Cycle

Plants have a life cycle split between two multicellular stages: a haploid stage—with cells containing one set of chromosomes—and a diploid stage—with cells containing two sets of chromosomes. The haploid stage is the gamete-producing gametophyte, and the diploid stage is the spore-producing sporophyte.
