SedentaryMood-Study (Part VII)

The following article is part of a series about the "SedentaryMood-Study".

In the last article the practical implementation of the study was described. In the following and last blog post the result of the study is presented.

Result

The results indicate that there is a significant negative influence on the mood dimension alertness-fatigue and on the good-bad mood. In general terms, this means that sedentary behaviour contributes to higher fatigue. Sedenary units (≥ 30 minutes) in which no interruption took place have a particularly negative effect compared to interrupted units.
With regard to the good-bad mood, the results also point to a significant negative influence of sedentary time. This means that the sedentary time can contribute to a worse mood. Especially negative is the effect of the sedentary units (≥ 30 minutes), in contrast to interrupted sedentary units, on the good-bad mood.

Digital Media and Developing Minds Conference

Posted on

We're delighted to attend the "Digital Media And Developing Minds" conference on the 15th.-18th. October in Long Island, New York, USA. We'll debut our research solutions, with a strong focus on the mobile sensing capabilities of our experience sampling app movisensXS. Our platform offers researchers excellent data collection capabilities to capture on screen behaviour through tracking the use of multiple devices concurrently to get a complete view of participant mobile usage.

We invite delegates to take advantage of our experience and talk with us about our other Behavioural monitoring solutions. Including physiological activity monitoring that provides a complete overview of daily activity over extended durations. Our interactive solutions allow the development of intervention studies, with our activity sensors capable of assessing activity levels, sedentary behaviour time, and even such elements as outdoor exposure and using these parameters to trigger interventions within the app. Combining this with an understanding of the regular mobile phone app use and behaviour promises to offer a detailed insight in this nascent field.
We're looking forward to meeting you all for the first time!

Society for Psychophysiological research 2018

Posted on

movisens heads abroad to Canada for the 58th annual meeting of the Society for Psychophysiological Research. The meeting takes place in the Quebec convention centre from the 3rd to the 7th of October. We'll display our unique combination of physiological sensors and experience sampling software, with a key focus on the integration of the two platforms. We look forward to seeing some of our existing customers there, and meeting researchers keen to explore this nascent field.

Amongst a whole array of interesting talks, we're particularly looking forward to the Heart Rate Variability symposium from Julian Thayer on Saturday the 7th. We'd like to extend a warm welcome to all the delegates, and invite them to drop by our table and have a chat about what psychophysiological solutions we can provide for their research.

The practical implementation of the SedentaryMood-Study

In the last article the applied investigation plan was explained. The following article describes the practical implementation of the study.


Step by step

  • Preparation of the ethics proposal
  • Preparation of the respondent information and questionnaires
  • Creation of the study concept via the Ambulatory Assessment Platform movisensXS








  • Preparation of the necessary research equipment and the associated materials
  • Configuring and Starting Sensors











  • Install TriggerApp
  • Bluetooth low energy Establish connection between sensor and smartphone and select algorithm (Sedentary)








  • Pair the smartphone with movisensXS and load the created design on the smartphone
  • Instruction and instruction of test persons at the workplace
  • Start study!

    SedentaryMood-Study (Part V)

    The following article is part of a series about the "SedentaryMood-Study".

    Measurement times of the real-time study

    In the last article, the sedentary sedimentary triggered e diaries and the randomly selected queries were described. In the next step, the study plan used for the SedentaryMood-Study is explained. Here, the frequency of the mood polls during the course of a day plays an important role.

    The exact number of queries depends on the individual participant's level of activity and thus, as in this study, up to 12 queries per day can be expected. More mood queries per day over a longer period of time are not to be recommended in order not to overstrain the associated willingness of the test persons to participate and thus not to endanger the data quality.

    On the basis of study results, about three to five days - of which at least one weekend day - are necessary for a representative recording of sedentary behaviour. In view of this, the survey period, the SedentaryMood Study, lasted five days (three working days and two weekend days).

    The sample was recruited from the University of Newcastle (UoN, Australia) and the Karlsruhe Institute of Technology (KIT, Germany). Participation in the study was linked to the following inclusion criteria: official co-worker of the institution, no illness or injury, and the work was performed predominantly in a sedentary body position.

    SedentaryMood Study (Part IIII)

    The following article is part of a series about the "SedentaryMood-Study".

    Sedentary Triggered e-Diaries

    The methodical core of the "SedentaryMood-Study" is the use of Sedentary Triggered e-Diaries. As far as is known, no comparable technical solution has been implemented in any study to date.

    In this case, the application aims to capture psychological parameters precisely during long sitting phases. Sedentary behaviour is recorded, analysed in real time and mood queries are generated when defined thresholds are reached. The threshold for long sedentary behaviour is 30 minutes. The communication between smartphone (e-Diary) and accelerometer takes place via a Bluetooth low energy (BLE) connection.
    In the practical implementation of this study, Sedentary Triggerd e-Diaries as well as random time points in the daily routine were selected. In addition, at the end of a study day, the test persons were encouraged to subjectively indicate the entire duration of the completed day.

    Sedentary Mood Study (Part III)

    The following article is part of a series on the "SedentaryMood Study".

    Preparations to determine the body position

    As part of the "SedentaryMood Study," the Move 3 activity sensor was used for the first time to capture sedentary behavior as a primary target variable. Thus, some preparatory work was necessary in the run-up to the study. These were aimed primarily at the detection of the body position.

    In order to determine the most suitable carrying position for the activity sensor and thus to differentiate between sitting and upright body positions, two video studies were carried out. On the one hand in everyday life with different activities and body positions and on the other hand during office work in everyday working life.

    The evaluations of both measurements show that a carrying position of the activity sensor Move 3 between the sagittal axis and the longitudinal axis, an upright body position is assumed. If the sensor is in a position that exceeds the angular range of < 20° between the sagittal axis and the longitudinal axis, an upright body position is assumed. If the sensor is in a position that exceeds the angular range of > to the sagittal axis, then a seated / lying body position is specified.

    As the measured data of the activity sensor Move 3 analyzed, coupled with the e-Diary movisensXS and triggered with the SensorTrigger you will learn in the next article ...
