Perceived Vulnerability to Illness
BCS (stress question only), PCS1
To assess the individual’s perceptions of his or her vulnerability to illness
Type of Measure
Created for study
Using a 6-point response scale, respondents rate the extent to which they agree with three self-referent statements regarding their likelihood of becoming sick when stressed; their tendency to feel mentally and physically exhausted at the end of the day; and their likelihood of becoming sick relative to other persons. In PCS1, the scale was administered on two occasions, separated by one week, during the pre-quarantine baseline period (see PCS1 Trial Outline). In BCS, the single vulnerability to illness item was administered during the pre-challenge quarantine period (see BCS Trial Outline)1.
6-point response scale with no neutral option (range: 1 = I disagree very much to 6 = I agree very much). Higher values indicate greater perceived vulnerability to illness.
Number of Items
For PCS1, a total perceived vulnerability score can be derived by taking the sum across the three items.
1 Because this item was added to the BCS questionnaire battery after data collection had begun, perceived vulnerability to illness data are available for only 261 of the 399 BCS participants.
