The purpose of this research was to develop and evaluate psychometrically an abbreviated instrument to assess hope in adults in clinical settings The Herth Hope Index (HHI), a 12‐item adapted version of the Herth Hope Scale (HHS), was tested with a convenience sample of 172 ill adults Alpha coefficient was 0 97 with a 2‐week test‐retest reliability of 0 91 Criterion‐related validity was established by correlating the HHI with the parent HHS (r = 0 92), the Existential Well‐Being Scale (r = 0 84) and the Nowotny Hope Scale (r = 0 81) Divergent validity with the Hopelessness Scale was established (r= ‐ 0 73) Construct validity was supported through the factorial isolation of three factors (a) temporality and future, (b) positive readiness and expectancy, (c) interconnectedness These three factors accounted for 41% of the total variance in the measure
