CONTEXT: Hopelessness is a clinically important construct in patients with advanced illness.
OBJECTIVES: To evaluate the dimensionality, stability, and validity of the Beck Hopelessness Scale (BHS) in cancer patients receiving either curative or palliative treatment.
METHODS: Following a longitudinal design, we assessed a sample of cancer patients receiving either curative or palliative treatment (N = 315) at baseline and at follow-up after 12 months (N = 158). In addition to hopelessness, we measured depression (Patient Health Questionnaire-9), anxiety (General Anxiety Disorder-7), and health-related quality of life (Short-Form Health Survey-8). We analyzed dimensionality, stability, and construct validity of the BHS using confirmatory factor analysis, exploratory factor analysis and correlational analysis.
RESULTS: Independent of treatment intention, confirmatory factor analyses resulted in unsatisfactory model fits. Exploratory factor analysis yielded a two-factor solution in both groups receiving curative or palliative treatment. Factor 1 reflected pessimistic/resigned beliefs (Cronbach alpha ≥ 0.85), Factor 2 reflected positive beliefs toward the future (Cronbach alpha = 0.73). Both subscales showed significant associations with anxiety, depression, and decreased health-related quality of life. The factorial structure was partially replicated in patients being reexamined after 12 months (CMIN/DF = 2.130, Standardized Root Mean Square Residual = 0.0716, Comparative Fit Index = 0.904, Tucker-Lewis-Index = 0.883, Root Mean Square Error of Approximation = 0.085). Hopelessness scores were significantly higher in patients reporting suicidal ideation according to the Patient Health Questionnaire-9.
CONCLUSION: Our study demonstrates psychometric limitations of the BHS in patients receiving both curative and palliative treatment, suggesting reduced utility in cancer populations. Given the clinical importance of the construct, a cancer-specific approach to capture the unique meaning of hopelessness in patients with severe medical illness is recommended.
