NOTE. HARS = Hamilton Anxiety Rating Scale; ASImental =Fear of Mental Dyscontrol subscale of the Anxiety Sensitivity Index; ASItotal = Anxiety Sensitivity Index total score; STAI-T = Spielberger State-Trait Anxiety Inventory – Trait Scale; PANAS-N = Negative Affect Scale of the Positive and Negative Affect Schedule; DRS-2= Mattis Dementia Rating Scale total raw score; MFQ frequency = the Memory Functioning Questionnaire general frequency of forgetting subscale. χ² = chi-square statistic reflecting overall model fit (p > .05 indicates a good fit); CFI = Comparative Fit Index (≥ .90 indicates a good fit); TFI = Tucker-Lewis Index (≥ .90 indicates a good fit); RMSEA = Root Mean Square Error of Approximation (≤ .05 is considered a very close fit; .05 – .10 is considered a moderate fit); SRMR = Standardized Root-Mean-Square Residual (used for continuous outcomes, ≤ .08 is considered a good fit). β = fully standardized coefficient. Statistical significance is based on z-score transformations of raw estimates. Estimates reported are standardized coefficients, and statistical significance (p) is based on z-score transformations of raw estimates.

Significance of the indirect effect was determined by examining bootstrapped bias corrected 95% confidence intervals.
