Table 3. SEM Estimation Results.
The “To” columns and “From” rows represent the left-hand side and right-hand side variables in the structural equation model. Direct, indirect, and total effects (t-tests in parenthesis) for the endogenous variables (percent of weight loss, assessment of challenge for eating behavior, and assessment of challenge for physical activity behavior, adherence to eating behavior, adherence to physical behavior, and efficacy for activity and eating behavior) and exogenous variables (age, gender, SNAP, ILE-other, ILE-family, and PSS). Controls for site and community health worker using Huber-White standard errors.
