Guidelines For Interpretive Interview Fidelity In Mixed Methods Research Within The Context Of A Randomized Controlled Trial, Amanda L. Garrett
Guidelines For Interpretive Interview Fidelity In Mixed Methods Research Within The Context Of A Randomized Controlled Trial, Amanda L. Garrett
College of Education and Human Sciences: Dissertations, Theses, and Student Research
Interviews fascinate and capture individuals’ attention. Researchers value the data they glean from interviews, while participants enjoy being asked to share their voices and opinions. Some of the most complex, stringent research designs are now being revised to include interviews, such as randomized controlled trials. But, how do we know that the interviews that are conducted are valid? We need to know more about how interviews are developed and delivered within the context of intervention research. Therefore, the aim of this methodological dissertation is to create a set of recommendations for interpretive interviews in a mixed methods randomized controlled trial. …

Validity Of Wearable Fitness Trackers On Sleep Measure, Alyssa Keill
Research Presentations
Wearable trackers that detect sleep offer users a way to track their sleep quality and patterns without the use of expensive equipment. Few studies have tested the validity of these trackers on sleep measure. PURPOSE: To examine the validity of the Actigraph GT9X (AG), SenseWear Mini Armband (SW), Basis Peak (BP), Fitbit Charge HR (FB), Jawbone UP3 (JU), and Garmin Vivosmart (GV) for estimating sleep variables as compared with a sleep diary. METHODS: 78 healthy individuals participated in the study. Group 1 (n= 38) and wore the AG, SW, BP, and FB or Group 2 (n = 40) …
Examining The Validity Of Fitbit Charge Hr Tm For Measuring Heart Rate In Free-Living Conditions, Jung-Min Lee, Hyun-Sung An, Seoung-Ki Kang, Youngdeok Kim
Examining The Validity Of Fitbit Charge Hr Tm For Measuring Heart Rate In Free-Living Conditions, Jung-Min Lee, Hyun-Sung An, Seoung-Ki Kang, Youngdeok Kim
Research Presentations
Optical blood flow sensors (i.e. photoplethysmographic techniques) have recently been utilized in wearable activity trackers. The Fitbit Charge HRTM (FBHR) is one of the widely recognized wearable activity trackers that utilizes Fitbit’s proprietary PurePulse optical heart rate (HR) technology to automatically measure wrist-based HR. Despite its increasing popularity, however, no study to date has addressed the validity of FBHR for measuring HR in free-living conditions. PURPOSE: The purpose of this study was to examine the validity of FBHR for measuring HR using a chest strap Polar HR monitor (PHR) as a reference measure in free-living conditions. METHODS: Ten …
