Study summary

This study tests the effectiveness of using a new mobile application (Bingocize®) to improve older adults' (a) adherence to an engaging exercise program, and (b) aspects of functional performance, health knowledge, dietary habits, and cognition.

Read the detailed description

Health-promoting interventions designed to improve physical and mental fitness can help reduce health care costs; they can also help maintain, or even improve, older adults' quality of life. However, getting older adults to adhere to health-promoting exercise interventions remains difficult because such programs are often perceived as being time-consuming, painful, or unenjoyable. The present study's objective is to investigate the effectiveness of a novel technological exercise intervention program for older adults (Bingocize); in doing so, the program has the potential to improve older adults' independence and quality of life. Older adults will participate in a pre/post-intervention design with random assignment to either the experimental or one of three comparison/control groups; each group will play Bingocize in a social setting with other older adults. Participants in the experimental group will use the app to engage in twice-weekly Bingocize sessions for twelve weeks (i.e., Bingo+Exercise+Health Education); control groups will also use the app for twelve weeks but for either health education-only, exercise-only, or bingo-only.

What researchers measure

Primary outcomes

  1. Executive Function Inhibition Measure 1: Flanker Task

    Flanker Task designed to measure inhibition, part of the EXAMINER Battery (for scoring method, see References section). EXAMINER generates a score that combines reaction time and accuracy data from the incongruent trials. This scoring method generates accuracy and reaction time sub-scales that range in value between 0 and 5, and the ultimate composite score ranges in value between 0 and 10. Minimum=0, Maximum=10, higher = better.

    Time frame: Baseline and 12 Weeks

  2. Executive Function Measure: Updating Verbal Working Memory

    Dot Counting Task designed to measure verbal working memory, part of the EXAMINER Battery (for scoring method, see References). EXAMINER generates a score is the total number of items correctly recalled across all six trials. Minimum=0, Maximum=27, higher = better.

    Time frame: Baseline and 12 Weeks

  3. Executive Function Measure: Set Shifting Task

    Set Shifting Task designed to measure attention during task switching, part of the EXAMINER Battery (for scoring method, see References). EXAMINER generates a score that combines reaction time and accuracy data from the incongruent trials. This scoring method generates accuracy and reaction time sub-scales that range in value between 0 and 5, and the ultimate composite score ranges in value between 0 and 10. Minimum=0, Maximum=10, higher = better.

    Time frame: Baseline and 12 Weeks

  4. Executive Function Measure: Verbal Fluency

    Verbal Fluency Task designed to measure fluency, part of the EXAMINER Battery (for scoring method, see References). EXAMINER generates a score that represents the total number of words correctly recalled in two tasks: phonemic (letter) and semantic (category). Minimum=0, Maximum=unlimited, higher = better.

    Time frame: Baseline and 12 Weeks

  5. Chair Stands: Change in Lower-body Muscular Strength

    number of completed chair stands in 30 seconds, minimum=0, higher = better

    Time frame: Baseline and 12 Weeks

  6. Change in Dynamic Balance: 360 Degree Turns

    360 degree turns: time to complete. No minimum or maximum value set. Lower = better.

    Time frame: Baseline and 12 Weeks

  7. Executive Function Measure of Inhibition: Continuous Performance Test

    Continuance Performance Task is classic response inhibition task, part of the EXAMINER Battery (for scoring method, see References). The score here represents the number of trials out of 100 that the participant responded correctly (i.e., either successfully responded or successfully inhibited a response).

Limitations and caveats
COVID-19 Pandemic began in the Middle of this Intervention, resulting in the loss of approximately 35-40% of the overall participant sample who were in the middle of the clinical trial intervention and had to withdraw from the study. Other data collection waves were started and completed before the pandemic, or started and completed after the pandemic, which introduces the possibility of history effects impacting interpretations of the data from participants who did complete the trial.
