0 = attachment anxiety and avoidance below the mean Group 1 = attachment anxiety and avoidance above the mean Study 4: 1. Partners’ practical support and perceived partner control and criticism (top figures) for groups low (group = 0) and high (group = 1) in attachment avoidance (left) and low and high in attachment anxiety (right) 2. Partners’ emotional support and perceived partner control and criticism (bottom figures) for groups low (group = 0) and high (group = 1) in attachment avoidance (left) and low and high in attachment anxiety (right) 0 = attachment anxiety and avoidance below the mean Group 1 = attachment anxiety and avoidance above the mean Study4: 1. Partners’ practical support and distancing (top figures) for groups low (group = 0) and high (group = 1) in attachment avoidance (left) and low and high in attachment anxiety (right) 2. Partners’ emotional support and distancing (bottom figures) for groups low (group = 0) and high (group = 1) in attachment avoidance (left) and low and high in attachment anxiety (right) Group 0 = attachment anxiety and avoidance below the mean Group 1 = attachment anxiety and avoidance above the mean
1. Partners’ practical support (top figures, M = 3.75, SD = 1.13) for groups low (group = 0) and high (group = 1) and in attachment avoidance (left) and low and high in attachment anxiety (right) 2. Partners’ emotional support (bottom figures, M = 1.80, SD = 1.03) for groups low (group = 0) and high (group = 1) and in attachment avoidance (left) and low and high in attachment anxiety (right) 0 = attachment avoidance and anxiety below the mean Group 1 = attachment anxiety and avoidance above the mean Study 2: 1. Partners’ practical support (top figures, M = 4.31, SD = 1.13) for groups low (group = 0) and high (group = 1) and in attachment avoidance (left) and low and high in attachment anxiety (right) 2. Partners’ emotional support (bottom figures, M = 3.05, SD = 1.14) for groups low (group = 0) and high (group = 1) and in attachment avoidance (left) and low and high in attachment anxiety (right) Group 0 = attachment avoidance and anxiety below the mean Group 1 = attachment anxiety and avoidance above the mean
(2) Second, we took the partial derivative with respect to and solved for = 0 = = = for = 0 If ≠ 0 (3) Finally, we solved by substituting values for (i.e., -1 SD and +1 SD values for z or recipients’ attachment avoidance) and re-centered the x values (partners’ practical support) against the true mean value.
