Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Community Healthy Activities Model Program for Seniors (CHAMPS) Physical Activity Questionnaire for Older Adults | Baseline and 4 months (follow up) .The 4-month post-intervention follow-up assesses average physical activity over the past 4 weeks. | Report minutes of moderate to vigorous level physical activity per week. Weekly frequency and duration of physical activity is used to calculate minutes of moderate to vigorous level physical activity (MVPA) per week. |
| Activity Counts Per Minute (CPM). | Baseline and 4 months (follow up) | Measured through a wrist-worn accelerometer (ActiGraph Model GT3X) worn for 7 days. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Stroop C-W (Color-word Test) of the Stroop Neuropsychological Screening Test | Baseline and 4 months (follow up) | Measure of executive function. The Stroop test assesses the ability to inhibit cognitive interference. Color-words are printed in inconsistent color ink. Subjects are asked to name the color of the ink and not read the word. Score range is the number of words named correctly minus errors in 30 seconds and ranges from 0-77. Higher scores reflect better performance and less interference on reading ability. Raw scores were converted to z-scores utilizing baseline means and standard deviations. Z-scores were then combined into composite scores of executive function. |
| Verbal Fluency Test - Animals | Baseline and 4 months (follow up) | This is a widely used measure of verbal fluency (or semantic memory) in which the participant is asked to generate exemplars of each of two categories (animals, fruits and vegetables) within a 60-second time limit. The primary measure of performance is the number of unique exemplars generated within the time limit. The score is the total number of animals (Animal Total) and vegetables (Vegetable Total) named within the time limit. A higher score means a better outcome. Scores range from 0 with no upper limit. |
| Symbol Digit Modalities Test | Baseline and 4 months (follow up) | Measure of the speed of perceptual processing in which the participant is asked to identify and name the numbers which belong with consecutively presented symbols for 90 seconds. The score is the number of digits correctly identified within the 90-second time limit - a higher score means a better outcome. Scores range from 0 to 110. |
| Digit Span Test - Forward | Baseline and 4 months (follow up) | This is a widely used measure of working memory (or attention) in which the participant is read number sequences of increasing length and then asked to repeat each sequence forward (Digits Forward) or backward (Digits Backward). The primary measure of performance is the number of digit sequences correctly recalled in each subpart (Digits Forward, Digits Backward). Each sequence for Digits Forward and Digits Backward is scored as error (0) or correct (1) - a higher score means a better outcome. |
| Digit Ordering Test | Baseline and 4 months (follow up) | This is a measure of working memory in which the participant is read number sequences of increasing length and is then asked to reorder the digits and say them in ascending order. Score range is 0 - 12 with a higher score meaning a better outcome. |

Measure of executive function. The Stroop test assesses the ability to inhibit cognitive interference. Color-words are printed in inconsistent color ink. Subjects are asked to name the color of the ink and not read the word. Score range is the number of words named correctly minus errors in 30 seconds and ranges from 0-77. Higher scores reflect better performance and less interference on reading ability. Raw scores were converted to z-scores utilizing baseline means and standard deviations. Z-scores were then combined into composite scores of executive function.

Stroop C-W (Color-word Test) of the Stroop Neuropsychological Screening Test
Measure of executive function. The Stroop test assesses the ability to inhibit cognitive interference. Color-words are printed in inconsistent color ink. Subjects are asked to name the color of the ink and not read the word. Score range is the number of words named correctly minus errors in 30 seconds and ranges from 0-77. Higher scores reflect better performance and less interference on reading ability. Raw scores were converted to z-scores utilizing baseline means and standard deviations. Z-scores were then combined into composite scores of executive function.
Time frame: Baseline and 4 months (follow up)
Population: Pre to post change within group for participants that completed pre and post data collection.

Symbol Digit Modalities Test
Measure of the speed of perceptual processing in which the participant is asked to identify and name the numbers which belong with consecutively presented symbols for 90 seconds. The score is the number of digits correctly identified within the 90-second time limit - a higher score means a better outcome. Scores range from 0 to 110.

Trail Making Test (TMT) Part A
Measure of executive function. In part A, the subject connects a series of encircled numbers in numerical order. In part B, the subject connects encircled numbers and letters in numerical and alphabetical order, alternating between the numbers and letters. TMT score is the time in seconds it takes the subject to complete the test. A lower score/time is better. TMT A scores range from 0-180 seconds and TMT B scores range from 0-300 seconds. Raw scores were converted to z-scores utilizing baseline means and standard deviations. Z-scores were then combined into composite scores of executive function.

Verbal Fluency Test - Animals
This is a widely used measure of verbal fluency (or semantic memory) in which the participant is asked to generate exemplars of each of two categories (animals, fruits and vegetables) within a 60-second time limit. The primary measure of performance is the number of unique exemplars generated within the time limit. The score is the total number of animals (Animal Total) and vegetables (Vegetable Total) named within the time limit. A higher score means a better outcome. Scores range from 0 with no upper limit.
