Note. All like effects (e.g. W1 to W3; W3 to W7) were set to be equal, giving us an overall test of whether previous scores influenced subsequent scores, as shown with the unstandardized estimates (B). We also reported the standardized betas (β) for W1 to W3 and W3 to W7.
p<.05,
p<.01.
The following parameters were set to covary in the model; husbands and wives W1 physical activity, husbands and wives W1 depressive symptoms, husbands W1 physical activity and depressive symptoms, wives W1 physical activity and depressive symptoms, all possible combinations of husbands and wives W1 age, W1 disability, W1 perceived support, W1 physical activity, and W1 depressive symptoms. Husbands and wives error terms for W1 depressive symptoms and for W1 physical activity were also set to covary. The same was done for the W3 error terms.
