This article provides insight related to the internal validity threat of measurement reactivity in RCTs and gives suggestions to reduce its effects.

Specifically, the frequent interviews exposed participants to catheter-related concerns and provided them with ideas as to how to better manage them.

The calendar and interview questions were reactive by increasing participants' self-monitoring of catheter problems. Our belief that the calendar was the probable cause of reactivity was not fully supported as the control group also learned about paying attention to urinary catheter problems by the questions asked through the seven bimonthly interviews. At the end, each item was recoded into eight categories and minor codes. The data were discussed and coded iteratively until three researchers reached consensus. The data analyzed were from the participants' brief responses to the final study question concerning their perceived study participation value. The original sample consisted of 202 community-living adults with long-term indwelling urinary catheters. Measurement reactivity is a phenomenon that occurs when the fact of participating in a study that is aimed to measure certain behaviors influences the way in which the participant displays these. The study involved a secondary data analysis of responses from 145 participants who completed a 12-month long RCT. The implications of measurement reactivity on self-monitoring and suggestions for minimizing its effect will be discussed. They should know the definition of an element and be able to identify metals and non-metals using the periodic table. The reactivity series is also known as the activity series of metals. Learners should be familiar with the periodic table of elements. The starting materials are always pure elements, such as a pure zinc metal or hydrogen gas, plus an aqueous compound.

The objective of this article is to describe how self-monitoring contributed to measurement reactivity in a randomized clinical trial (RCT). The reactivity series is an ordering of metals from most reactive to least reactive. In order to identify poor responders to an antiplatelet drug, laboratory tests of platelet function that specifically explore the platelet activation pathway that is targeted by the drug should be utilised. A single replacement reaction, sometimes called a single displacement reaction, is a reaction in which one element is substituted for another element in a compound.
