The testing procedure being one, [21,24] where the reliability between raters (i.e. Reliability and validity are two very important qualities of a questionnaire. $\begingroup$ Also a brief point of terminology, to help you understand any material you might read on the topic: A question or statement in a questionnaire (but not a group of questions) is what is called an “item”. Yes (N–A)! In the present investigation, fourteen of the reviewed tests as listed in Table 2 were not considered valid for any of the military tasks. These tasks correspond unanimously to the duties of all soldiers during their first 12 weeks of basic military training in the Swedish Armed Forces, regardless of their future military occupational speciality (MOS). 0000005706 00000 n Some statistical procedures such as regression analysis will not work as well, or at all on data set with missing values. Internal Reliability If you have a scale with of six items, 1–6, 1. The absolute intra-rater reliability measured as SEM, was acceptable with the exception of the side-bridge with a SEM% value >15%, Table 4. https://doi.org/10.1371/journal.pone.0132185.t004. Like face validity, content validity is based on subjective judgement. The overhand grip was considered more relevant in different military situations. ��/��iE��7� �Bk���#VL5�d����3����q@���uG�5C�s��^��� �/���M 0 ]pZ� endstream endobj 60 0 obj 243 endobj 38 0 obj <<

PLOS ONE promises fair, rigorous peer review, Time is the amount of time in seconds it takes them to complete the test. Data Availability: All relevant data are within the paper and its Supporting Information files. Reliability sets the limits of validity of any test [21]. Although research has shown that data obtained from physical tests can be used independently to predict future injury occurrence [2,15–17] or physical performance [14,18–20], the content validity of these tests are often not reported. 0000009534 00000 n After we explain procedures, we provide short Questionnaire Reliability. During the second test, the raters were blinded to the results of the first test. You will find links to the example dataset, and you are encouraged to replicate this example.

Fourteen of the tests were considered valid for measuring lifting tasks. The SEM% for the side-bridge (left side) was 17%, with an SRD of 50 seconds. Yes We analyzed how nurse researchers have defined and calculated the CVI, and found considerable consistency for item-level CVIs (I-CVIs). Conceived and designed the experiments: HL MT LB. It is most commonly used when you have multiple Likert questions in a survey/questionnaire that form a scale and you wish to determine if the scale is reliable.
