Validity and reliability of a ruler drop test to measure dual-task reaction time, choice reaction time and discrimination reaction time This study aimed to identify the validity, reliability, and usefulness of four newly developed RT testing protocols among athletes from agility-saturated (AG) and non-agility .The results showed that the relative reliability was good for the choice ruler drop (ICC = 0.81), moderate for the dual-task ruler drop test (ICC = 0.70) and discrimination ruler drop test (ICC = 0.72), and good for simple ruler drop test. However, the simple ruler drop test had poor reliability (ICC = 0.57).Although early research on the ruler-drop test revealed acceptable test-retest reliability 16, 17 and adequate criterion validity in collegiate athletes (r = 0.45), 18 a recent study by MacDonald et al, 11 in which clinical reaction times were compared with results obtained by computerized methods, indicated that reaction times obtained with .
Specifically, the measurements used so far include both computer-based and -independent protocols, where a subject’s fine motor control movement task has been used, such as to press a button or catch a dropped object in response to flashed light (e.g., “ruler drop test”), respectively (Carling et al., 2009; Eckner et al., 2015; Geiger et .
Background The aim of this study was to determine the absolute and relative reliability of the Ruler Drop Test (RDT) for assessing dual-task, choice, and discrimination reaction time. In addition, the construct validity of the RDT is examined in comparison to the Deary-Liewald reaction time (DLRT). Methods Tests were administered by the same .

test purpose: to measure reaction time, hand-eye quickness and attentiveness. equipment required: 1 meter long ruler or Yardstick, calculator. pre-test: Explain the test procedures to the subject. Prepare forms and record basic information such as age, gender and test conditions. Write down which is the preferred hand. Both tasks were adapted from the well-known ruler drop test of RT and involve manually grasping a falling vertical shaft upon its release, with the complex task employing a go/no-go paradigm based .
Reaction time (RT) is one of the key factors in combat sports. Its high level is a predictor of sporting success. Therefore, RT tests are an important diagnostic tool in combat sports. The implementation of some conventional psychomotor tests in virtual settings can facilitate research and improve the objectivity and standardization of the measurement .
Briefly, this test uses a 'ruler-drop' paradigm to measure simple reaction time, and go/nogo reaction accuracy under time pressure (i.e., the decision to grasp the stick or let it fall must occur .

Context: Researchers have confirmed that the ruler-drop test could be included as part of a multifaceted concussion-assessment battery and potentially as a way to track recovery from head injury. However, it is unclear if this clinical test of reaction time would be characterized by inconsistent performance because of practice effects.
These are some recommendations to ensure a test is valid: Clearly Define the Construct: Begin by clearly defining what the test is intended to measure.; Expert Review: Have subject matter experts review the test items to ensure they are appropriate and relevant to the construct being assessed.; Pilot Testing: Pilot test the items with a small sample of individuals .The results showed that the relative reliability was good for the choice ruler drop (ICC = 0.81), moderate for the dual-task ruler drop test (ICC = 0.70) and discrimination ruler drop test (ICC = 0.72), and good for simple ruler drop test. However, the simple ruler drop test had poor reliability (ICC = 0.57). The RDT shows construct validity .In evaluating a measurement method, psychologists consider two general dimensions: reliability and validity. Reliability. Reliability refers to the consistency of a measure. Psychologists consider three types of consistency: over time (test-retest reliability), across items (internal consistency), and across different researchers (inter-rater .The aim of this study was to determine the absolute and relative reliability and validity of two reaction time (RT) tests in older adults using long-term facility: the ruler drop test (RDT, a simple RT) and the Deary-Liewald RT task (DLRT, simple .
[9][10][11][12] Despite of having acceptable test-retest reliability, drop ruler test has certain limitations for example-it is tedious, require more attempts, less accurate, lack of hand-eye co . is the traditional ruler drop test (RDT) and, althoug h the RDT measures RT plus movement time, it continues to be an acceptable means of measuring simple RT (Del Rossi, Malaguti, & Del Rossi, 2014).Test reliability refers to the degree to which a test is consistent and stable in measuring what it is intended to measure. Reliability will depend upon how strict the test is conducted and the individual's level of motivation to perform the test. The following link provides various factors influencing the results and test reliability. Validity
Background Reduced cognitive function, particularly executive function (EF), is associated with an increased risk of falling in older people.
