Test Information Function (TIF) and Standard Error of Measurement (SEM) Curve for the subscales of rumination and distraction/problem-solving separately. Note: Upper panel: Solid lines; left y-axis = total information aggregated across all items assessing rumination along the latent trait (θ, theta) ranging from −3 to 3. Dashed lines; right y-axis = standard error of measurement for the scale of rumination along the latent trait (θ, theta) ranging from −3 to 3. Lower panel: Solid lines; left y-axis = total information aggregated across all items assessing distraction/problem-solving along the latent trait (θ, theta) ranging from −3 to 3. Dashed lines; right y-axis = standard error of measurement for the scale of distraction/problem-solving along the latent trait (θ, theta) ranging from −3 to 3
