  FIGURE 1. Parallel mediation model linking Type D personality with HbA1c. People with Type D personality were coded as 1 and others were coded as 0. a 1: Regression coefficient for Type D personality predicting diabetes distress; a 2: regression coefficient for Type D personality predicting social isolation; b 1: regression coefficient for diabetes distress predicting HbA1c while holding Type D personality and social isolation constant; b 2: regression coefficient for social isolation predicting HbA1c while holding Type D personality and diabetes distress constant; c′: regression coefficient for Type D personality predicting HbA1c while holding diabetes distress and social isolation constant (direct effect); and c: total effect.

  FIGURE 2. Parallel mediation model linking Type D personality with HRQOL while controlling for covariates. People with Type D personality were coded as 1 and others were coded as 0. a 1: Regression coefficient for Type D personality predicting diabetes distress; a 2: regression coefficient for Type D personality predicting social isolation; b 1: regression coefficient for diabetes distress predicting HRQOL while holding Type D personality, social isolation, gender and education level constant; b 2: regression coefficient for social isolation predicting HRQOL while holding Type D personality, diabetes distress, gender and education level constant; c′: regression coefficient for Type D personality predicting HRQOL while holding diabetes distress, social isolation, gender and education level constant; c: total effect while controlling for gender and education level.
