Note. N = 677. Time 1 = intake; Time 2 = 12-month follow-up; Time 3 = 24-month follow-up; DASS-D = Depression scale of the Depression Anxiety Stress Scales; ADIS-D = Anxiety Disorders Interview Schedule for DSM-IV (ADIS-IV) ratings of major depression; BDI = Beck Depression Inventory; APPQ = Agoraphobia scale of Albany Panic and Phobia Questionnaire; ADIS-Ag = ADIS-IV ratings of agoraphobia; ADIS-A = ADIS-IV ratings of DSM-IV panic disorder/agoraphobia criterion A (recurrent panic attacks); ADIS-B = ADIS-IV ratings of DSM-IV panic disorder/agoraphobia criterion B (worry/change in behavior); λ = factor loading; τ = indicator intercept. All loadings are significant at p < .001. Model fit as shown below is for the final longitudinal invariance models.

^aModel fit: χ²(21) = 25.24, p = .24; CFI = 1.00; TLI = 1.00; RMSEA = 0.02; SRMR = .02.

^bModel fit: χ²(46) = 299.74, p < .001; CFI = .96; TLI = 0.95; RMSEA = 0.09; SRMR = .06.

^cModel fit: χ²(121) = 208.92, p < .001; CFI = .97; TLI = 0.96; RMSEA = 0.03; SRMR = .05.
