Trial Outcomes & Findings for Caminamos: A Smartphone App for Latinas to Connect With Walking Partners (NCT NCT03854916)
NCT ID: NCT03854916
Last Updated: 2023-07-14
Results Overview
The Community Healthy Activities Model Program for Seniors (CHAMPS) is a 41-item PA questionnaire that measures self-reported minutes-per-week of PA calculated as total weekly caloric expenditure for all PA. It was developed for underactive populations and validated among older adults. However, CHAMPS has been used with younger and racially/ethnically diverse populations; it is sensitive to change specifically in Latino and other populations including ones younger than senior age. The CHAMPS asks about activities undertaken for exercise, daily activities that are physical in nature, and physically active recreational activities during "a typical week in the past 4 weeks."

The Community Healthy Activities Model Program for Seniors (CHAMPS) is a 41-item physical questionnaire that measures self-reported minutes-per-week of physical activity calculated as total weekly caloric expenditure in all physical activity. Hours and minutes per week were assessed for different types of physical activity. Using body weight and minutes of physical activity (by type), total caloric expenditure was calculated. Data is presented as a T-score with higher values (positive) indicating more calories expended at 8 weeks compared to baseline. Range = 2.5-145.2 kilocalories/kg/hr in the World Walking App condition; range = 6.9-120.1 kilocalories/kg/hr in the Caminemos condition. This measure was administered at 8 weeks to measure changes in physical activity.

The Social Support for Exercise Survey is a 10-item self-report measure that assesses perceived receipt of social support for exercise, i.e., how often their friends or family members (separately rated) encouraged their exercise behaviors during the previous 3 month. Each question uses a likert-type scale ("1/none, 2/rarely, 3/a few times, 4/often, 5/very often") with higher mean score indicating more support from family and friends. Minimum mean score for the scale = 10; maximum mean score = 50.

The 12-Item Short Form Health Survey (SF-12) is a 12-item questionnaire that measures functional health and well-being (i.e., health-related quality of life; HRQOL). Answer scales include likert-type scales and dichotomous answer choices. The validated scoring for SF-12 was used; scoring is done by linear transformation with the mean score in the general US population being set to 50. Mean scores above 50 indicate better than average self-reported health. Range = 30.7-61.3 units in the physical component in Caminemos condition; range = 28.2-62.2 units in the physical component in the World Walking App condition. For the mental component, range = 14.8-60.7 in Caminemos condition; range = 18.9-62.9 in the World Walking App. Raw scores are provided.

Ten likert-type questions assessing user-friendliness of technology. Each question has five answer options that range from 1="Strongly Disagree" to 5="Strongly Agree". Scores range from 0-100. The participant's scores for each question are converted to a new number, added together and then multiplied by 2.5 to convert the original scores of 0-40 to 0-100. A score above 68 is considered above average. Higher scores indicate a more usable technology compared to lower. Raw scores are presented. Range = 20-100 for Caminemos; range = 15-95 for World Walking App. All scores averaged.
