  1. Abbreviations: IPAQ-SF International Physical Activity Questionnaire Short Form, NPAQ-Short Nordic Physical Activity Questionnaire Short, EQ-VAS EuroQol Visual Analogue Scale, UCLA University of California, Los Angeles, Data for four participants were imputed for average daily steps. Data for six participants was imputed for IPAQ-SF MVPA and minutes of sedentary time per day, NPAQ-Short MVPA minutes per day, EQ-VAS, UCLA Loneliness Scale Sum Score, and SEE Sum Score. Data for seven participants was imputed for IPAQ-Short minutes of walking per day and OEE-2 Sum. End point scores are unadjusted. Primary analysis is the multiple linear regression model adjusted for baseline score, baseline steps, age and sex. Coefficients > 0 means higher value in the PAM+MI group. Negative coefficients for IPAQ-SF Sedentary Time and UCLA Loneliness Scale Sum Score means less sedentary time and loneliness in the PAM+MI group. P-values < 0.05 is considered significant
