  1. The 95% confidence interval is for the difference in means between the two groups. Two-sided t tests were conducted without corrections for multiple comparisons. Different adverse psychological states are abbreviated as follows (Supplementary Table 1): IntEmo, intensity of emotions/emotional reactivity (I feel emotions very intensely); Hopeless, hopelessness (I feel hopeless about the future); TimeRunOut, despair/entrapment (time is running out for me); TrappedProb, feeling trapped (I feel trapped by my problems); Anxious, anxiety (I am constantly anxious and on edge); LifeImpossible, desperation (life is impossible if things don't change); Impulsive, impulsivity (I often act without thinking when I am upset); Burden, burdensomeness (I am a burden to others); NotBelong, lack of belongingness (I feel like I don't belong); NotAfraidDeath, acquired capability for death (I am not afraid of death or injury); No SocSupport, social support (I have no social support); NoPurpose, purposefulness (I do not have a sense of direction and purpose in life). All group differences were significant at the ≤0.01 level. Standard deviations are reported in parentheses. All psychological state items range from 1 to 5. The explicit association with death score (ExplAssoDeath) ranges on a scale from 0 to 100, and the IAT D score (IatDScore) ranges from –2 to 2.
