BACKGROUND: There are several ways to determine psychological resilience. However, the correlation between each measurement is not clear. We explored associations of baseline relative "resilience" and risk with later self-reported trait resilience and other biological/mental health indices. METHODS: We utilized baseline and follow-up survey data from 500 participants aged 30-64 in the community cohort. Baseline "relative" resilience was defined by: (a) negative life events (NLEs) in the six months before baseline and (b) depressive symptoms at baseline, yielding four groups of individuals: i) "Unexposed and well," "Vulnerable (depression)," "Reactive (depression)," and "Resilient." "Trait" resilience at follow-up was self-reported using the Connor-Davidson Resilience Scale (CD-RISC). Associations between relative resilience at baseline, CD-RISC, and heart rate variability (HRV) indices at follow-up were assessed with generalized linear regression models after adjustments. Associations between baseline resilience and subsequent loneliness/depression indices were also evaluated. RESULTS: Overall trait resilience and its subfactors at follow-up showed strong negative associations with "Reactive" at baseline (adj-beta for total CD-RISC score: -11.204 (men), -9.472 (women)). However, resilience at baseline was not associated with later HRV, which was compared with the significant positive association observed between CD-RISC and HRV at the same follow-up time point. The "Reactive" exhibited significantly increased depressive symptoms at follow-up. The overall distribution pattern of CD-RISC subfactors differed by baseline resilience status by sex. CONCLUSIONS: The "relative" resilience based on the absence of depression despite prior adversity seems to be highly related with trait resilience at follow-up but not with HRV. The sub-factor pattern of CD-RISC was different by sex.
