Fig 1.
Relationships between DASS subscales scores and resilience scores.
There was significant inverse correlation between resilience and Depression (A), Anxiety (B), Stress (C) and Total (D) DASS self-rating measures.
Fig 2.
Representative recording of heart rate, respiratory rate and skin conductance level in one subject before and during presentation of acoustic stimuli (Stim.) on the background of mental arithmetic task; shaded area corresponds to the task.
Note consistent SCL responses to startle stimuli, without accompanying cardiac or respiratory responses; and reduction of the respiratory sinus arrhythmia during the task.
Fig 3.
Relationships between sigh frequency during mental arithmetic task and resilience score (A) and habituation slope of startle responses F(B). Inset in (A) shows typical sigh morphology.
Fig 4.
Relationship between increase in skin conductance level during mental arithmetic task and the Anxiety score of the DASS scale.
Fig 5.
Habituation of skin conductance (sweating) responses to acoustic startle stimuli can discriminate between high- and low-resilient individuals.
A–raw data records of ECG, respiration and skin conductance level (SCL) during presentation of acoustic startle stimulus (sound; 50 ms, 95 dB). B–pattern of habituation of SCL responses in one high-resilient (CD-RISC score = 78; open circles) and one low-resilient (CD-RISC score = 39; closed circles) individual. Dashed lines represent habituation slopes determined by linear regression.
Fig 6.
Relationships between habituation of the SCL component of startle response and psychometric scores.
There was significant inverse correlation between the habituation slope and resilience score (A) and significant positive correlation between the habituation slope and Depression (B), Anxiety (C) and Total (D) scores of the DASS scale.
