Abstract
Hope is important in the rehabilitation of persons with schizophrenia, through scales to measure hope are not appropriate for this population. The purpose of this cross-sectional study was to identify the psychometric properties of the Schizophrenia Hope Scale-9 (SHS-9) using data from 83 people with schizophrenia in four mental health centers and 762 healthy persons from two universities in South Korea. The mean (standard deviation) SHS-9 score of the participants with schizophrenia and healthy participants was 11.24 (4.90) and 14.83 (3.10), respectively. Lower scores indicate a lower level of hope. The internal consistency alpha coefficient was 0.92 with a 4-week test-retest reliability of 0.89. Criterion-related construct validity was established by examining the correlation between the SHS-9 and the State-Trait Hope Inventory scores. Divergent validity was identified through a negative relationship of SHS-9 with the Beck Hopelessness Scale. The construct validity of the SHS-9 was confirmed through principal component analysis with extraction methods, which resulted in a one-factor solution, accounting for 49–60% of the total item variance.. This study provided evidence for the validity and reliability of the SHS-9; therefore, it could be used to measure hope in people with schizophrenia.
