Insights

The Spanish (Peru) Child-OIDP is a validated tool for assessing oral health

Area of Science:

  • Oral Health Research
  • Psychometrics
  • Pediatric Dentistry

Background:

  • Assessing the impact of oral conditions on children's quality of life is crucial.
  • The Oral Impacts on Daily Performance (Child-OIDP) is a key instrument, but requires robust validation in different cultural contexts.
  • Previous validation studies may not have fully explored its psychometric properties.

Purpose of the Study:

  • To validate the psychometric properties of the Spanish (Peru) version of the Child-OIDP.
  • To assess content, face, criterion, and construct validity.
  • To evaluate internal and external reliability of the Child-OIDP in a Peruvian child population.

Main Methods:

  • A cross-cultural adaptation of the Child-OIDP into Spanish was performed.
  • The study involved 903 children aged 11-12 years from public schools in Lima, Peru.
  • Psychometric properties were evaluated through pilot and main studies, including validity and reliability assessments.

Main Results:

  • The Child-OIDP demonstrated strong criterion validity, correlating significantly with self-perceived oral health, treatment needs, and satisfaction.
  • Exploratory factor analysis identified three underlying constructs: physical, psychological, and social health.
  • Internal consistency (Cronbach's alpha 0.62-0.65) and test-retest reliability (ICC 0.85) were found to be adequate.

Conclusions:

  • The Spanish (Peru) Child-OIDP is a reliable and valid instrument for measuring the impact of oral conditions on quality of life in children.
  • This study provides further evidence supporting the psychometric robustness of the Child-OIDP.
  • The findings support its use as an interviewer-administered tool in pediatric populations.

Oppositional Defiant Disorder01:30

Oppositional Defiant Disorder

A persistent pattern of angry or irritable mood, defiant behavior, or vindictiveness characterizes Oppositional Defiant Disorder (ODD). Symptoms must occur over at least six months, involve interactions with individuals beyond siblings, and meet specific diagnostic criteria to be clinically significant. The disorder affects emotional regulation, social interactions, and behavior, often manifesting early in life and influencing long-term development and functioning.

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.
Revisionist Views of Adolescent and Adult Cognition01:24

Revisionist Views of Adolescent and Adult Cognition

A revisionist approach to Jean Piaget's theory of cognitive development has brought new insights that challenge and reinterpret his established ideas. Piaget proposed that the formal operational stage, emerging in adolescence, represents the culmination of cognitive maturity. During this stage, individuals are said to develop abstract thinking, engage in systematic problem-solving, and show a form of egocentrism, believing others are as preoccupied with their behavior as they are themselves.
Parenting Styles01:27

Parenting Styles

Diana Baumrind's four parenting styles — authoritarian, authoritative, neglectful, and permissive — each influence children's socio-emotional development differently.
Authoritarian Parenting
This style is strict and controlling, with little room for open dialogue. Authoritarian parents demand obedience and often enforce rules with minimal warmth. Children raised this way may lack social skills and initiative, usually comparing themselves to others unfavorably.
Authoritative Parenting

Observational Studies01:11

Observational Studies

Observational studies are a type of analytical study where researchers observe events without any interventions. In other words, the researcher does not influence the response variable or the experiment's outcome.
There are three types of observational studies – Prospective, retrospective, and cross-sectional.
Prospective Study
Prospective studies, also known as longitudinal or cohort studies, are carried out by collecting future data from groups sharing similar characteristics. One example of...
Conduct Disorder01:28

Conduct Disorder

Conduct disorder is a complex mental health diagnosis characterized by a repetitive and persistent pattern of behavior that violates societal norms, the rights of others, or age-appropriate rules. The diagnostic criteria for conduct disorder require the presence of at least three problematic behaviors within the past 12 months, with at least one occurring in the past six months. These behaviors are grouped into four categories: aggression toward people and animals; destruction of property;...
