Although they are often discussed together, they pertain to different aspects of the quality of a measurement tool or a process. It is important to identify and analyze reliability and validity and, in turn, ensure that results obtained through data collection are valid and accurate.Understanding ReliabilityReliability is the consistency or repeatability of measurement. A measure should be regarded as reliable whenever it yields constant results under the same conditions. Researchers account for many forms of reliability. Test-retest reliability determines the consistency over time of a test. If you give the same test to the same individuals on different occasions, the outcomes should be fairly the same (Vilagut, 2023). Inter-rater reliability concerns agreement among multiple observers, raters, or assessors; it is especially important in clinical assessment or in cases where you’re doing qualitative research. Internal consistency reliability is the extent to which items on a test measure the same construct. Internal consistency can be calculated using Cronbach’s alpha; generally, for it to be regarded as being all right, it needs to be above 0.70.Understanding ValidityIn contrast, validity is the extent to which an instrument measures what it is supposed to measure. A test can be reliable but invalid—always producing the same scores that fail to measure the true concept. Validity is divided into several types: content validity, construct validity, and criterion-related validity. Content validity checks if the measurement of the concept is exhaustive. Construct validity checks to see if the test measures the theoretical construct it is supposed to measure. Criterion-related validity checks how one measure predicts an outcome based on another validated measure. For example, a new depression inventory would be compared to an already validated one to check concurrent validity.Interplay Between Reliability and ValidityAlthough distinct, reliability and validity are interrelated. A measure must first be reliable to be valid. Without consistent results (reliability), one cannot trust that the measure is capturing what it is supposed to (validity) (Perni et al., 2021). However, reliability alone is not sufficient. A bathroom scale that always adds 10 pounds provides reliable but invalid data. Therefore, researchers strive for high reliability as a prerequisite but must also assess various forms of validity to confirm that their tools genuinely measure the target variables.Evaluating Measures in PracticeWhen working, professionals and experts assess the reliability and validity of a test using excellent statistical methods and knowledge about the subject. Steps like development include statistics, panels of subject matter experts, and pilot tests. In nursing and healthcare research, instrument reliability and validity are very important because they provide evidence for evidence-based decisions (Clemett & Raleigh, 2021). Poorly validated tools may lead to wrong diagnoses or inappropriate interventions, causing patients to be harmed.a month ago03.06.20258Report issueBids(47)Dr. Ellen RMMISS HILLARY A+Dr. Aylin JMProf Double Rfirstclass tutorMiss DeannaMUSYOKIONES A+Dr ClovergrA+de plusSheryl HoganProWritingGuruIsabella HarvardBrilliant GeekWIZARD_KIMPROF_ALISTERAshley ElliePremiumLarry Kellyabdul_rehman_miss AaliyahShow All Bidsother Questions(10)assignmentNR 361 Week 6 Discussions & Assignment Information Systems in HealthcareFunctionality DB Unit 4MGMT 597 Week 3 Homeworkstatistic problemHOMEWORK FOR KIM WOODS ONLYphilosophyCatherine Essay Due 8/36 Page Paper about The Needs Assessment (Sources must with past 10 years)Discussion question 5
