Insights

The EValuation of INtervention Scale (EVIN) effectively measures non-pharmacological pain management for neonates. This validated scale ensures reliable assessment of interventions for reducing infant pain and stress during procedures.

Area of Science:

  • Neonatal care
  • Pain management
  • Evidence-based practice

Background:

  • Neonatal infants experience significant pain and stress during medical procedures.
  • Effective pain management is crucial to prevent adverse short- and long-term outcomes.
  • Non-pharmacological strategies are recommended for neonatal pain and stress reduction.

Purpose of the Study:

  • To validate the content of the EValuation of INtervention Scale (EVIN).
  • To test the reliability of the EVIN for evaluating non-pharmacological interventions.
  • To assess the suitability of EVIN in neonatal care settings.

Main Methods:

  • Content validation involved 80 multidisciplinary participants.
  • Inter-rater reliability was tested on preterm infants (N=12) during interventions.
  • The revised scale was assessed during invasive (N=16) and noninvasive (N=18) procedures using intraclass correlation coefficients (ICC).

Main Results:

  • High intraclass correlation coefficients (ICC) were achieved for both invasive (0.962) and noninvasive (0.970) procedures.
  • The results demonstrate excellent inter-rater reliability for the EVIN.
  • The scale showed strong consistency in evaluating interventions.

Conclusions:

  • The EValuation of INtervention Scale (EVIN) is a reliable tool.
  • EVIN is suitable for evaluating non-pharmacological support during painful neonatal procedures.
  • The scale supports evidence-based pain management in neonatal intensive care units.

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.

Self-Report Tests of Personality01:22

Self-Report Tests of Personality

Self-report inventories are objective personality assessments that use multiple-choice items or numbered scales, typically ranging from 1 (strongly disagree) to 5 (strongly agree). They are often called Likert scales after Rensis Likert. These inventories are widely used due to their ease of administration and cost-effectiveness. One of the most prominent examples is the Minnesota Multiphasic Personality Inventory (MMPI), initially developed in the 1940s to assess abnormal personality traits.

Measures of Intelligence01:29

Measures of Intelligence

Psychologists measure intelligence by using standardized tests that produce a score known as the intelligence quotient or IQ. To understand IQ tests, it's important to recognize the key principles behind their construction: validity, reliability, and standardization.
Validity refers to how well a test measures what it claims to measure. An intelligence test should accurately assess intelligence rather than another characteristic, like anxiety. Criterion validity is one way to evaluate this;...
