ABSTRACT
Few studies have examined how spiritual well-being changes over time in patients with heart failure. We conducted a secondary analysis of data from the Collaborative Care to Alleviate Symptoms and Adjust to Illness (CASA) trial (N = 314). Spiritual well-being was measured using the Functional Assessment of Chronic Illness Therapy-Spiritual Well-Being Scale (FACIT-Sp) at baseline and 12-month follow-up. Of the 165 patients with spiritual well-being data at follow-up, 65 (39%) experienced probable clinically meaningful changes (> 0.5 SD) in spiritual well-being (35 improved, 30 declined). Increased pain (p = 0.04), decreased dyspnea (p < 0.01), and increased life completion (p = 0.02) were associated with improvement in overall spiritual well-being. Exploratory analyses found different predictors for FACIT-Sp subscales.
ABSTRACT
BACKGROUND: Understanding patients' preferred role in decision making can improve patient-centered care. This study aimed to determine change and the predictors of change in preferred decision-making roles over time in patients with heart failure. METHODS AND RESULTS: During the CASA (Collaborative Care to Alleviate Symptoms and Adjust to Illness) trial, patients' preferred roles in decision making were measured using the Control Preferences Scale (range 1-5; higherâ¯=â¯less active; nâ¯=â¯312) at 4 timepoints over 1 year. The effect of the CASA intervention on preferred decision-making roles was tested using generalized linear mixed models. Whether preferences changed over time in the whole population was determined using linear regression. Demographic and health-related factors were examined as predictors of change using multiple linear regression. At baseline, most participants preferred active (score 1-2, 37.2%) or collaborative (score 3, 44.9%) roles. The CASA intervention did not influence preferred decision-making roles (P > 0.1). Preferences significantly changed over 1 year (P < 0.01), becoming more active (82.1%, 84.2%, 89.0%, 90.1% active/collaborative at each timepoint). Among all models and covariates, there were no significant predictors of change (P > 0.1). CONCLUSIONS: Patients' preferred roles in decision making change over time, but changes are not well predicted. Clinicians should frequently and directly communicate with patients about their preferred decision-making roles.

BACKGROUND: Dyspnea is a common and debilitating symptom that affects many different patient populations. Dyspnea measures should assess multiple domains. OBJECTIVE: To evaluate the reliability, validity, and responsiveness of an ultra-brief, multi-dimensional dyspnea measure. DESIGN: We adapted the DEG from the PEG, a valid 3-item pain measure, to assess average dyspnea intensity (D), interference with enjoyment of life (E), and dyspnea burden with general activity (G). PARTICIPANTS: We used data from a multi-site randomized clinical trial among outpatients with heart failure. MAIN MEASURES: We evaluated reliability (Cronbach's alpha), concurrent validity with the Memorial-Symptom-Assessment-Scale (MSAS) shortness-of-breath distress-orbothersome item and 7-item Generalized-Anxiety-Disorder (GAD-7) scale, knowngroups validity with New-York-Heart-Association-Functional-Classification (NYHA) 1-2 or 3-4 and presence or absence of comorbid chronic obstructive pulmonary disease (COPD), responsiveness with the MSAS item as an anchor, and calculated a minimal clinically important difference (MCID) using distribution methods. KEY RESULTS: Among 312 participants, the DEG was reliable (Cronbach's alpha 0.92). The mean (standard deviation) DEG score was 5.26 (2.36) (range 0-10) points. DEG scores correlated strongly with the MSAS shortness of breath distress-or-bothersome item (r=0.66) and moderately with GAD-7 categories (ρ=0.36). DEG scores were statistically significantly lower among patients with NYHA 1-2 compared to 3-4 [mean difference (standard error): 1.22 (0.27) points, p<0.01], and those without compared to with comorbid COPD [0.87 (0.27) points, p<0.01]. The DEG was highly sensitive to change, with MCID of 0.59-1.34 points, or 11-25% change. CONCLUSIONS: The novel, ultra-brief DEG measure is reliable, valid, and highly responsive. Future studies should evaluate the DEG's sensitivity to interventions, use anchor-based methods to triangulate MCID estimates, and determine its prognostic usefulness among patients with chronic cardiopulmonary and other diseases.

CONTEXT: The Functional Assessment of Chronic Illness Therapy-Spiritual Well-Being Scale (FACIT-Sp) is a 12-item measure of spiritual well-being in chronic illness originally developed in patients with cancer. The overall scale, a two-factor model (meaning/peace, faith), and a three-factor model (meaning, peace, faith) have been proposed for the FACIT-Sp, and consensus on the best factor structure has not been reached. In addition, the factor structure of the FACIT-Sp has not been considered in patients with heart failure. OBJECTIVES: To examine the factor structure of the FACIT-Sp in heart failure patients. METHODS: A confirmatory factor analysis framework was used to test three competing models on 217 patients with heart failure using data from the CASA (Collaborative Care to Alleviate Symptoms and Adjust to Illness) trial. The overall scale (single factor), two-factor, and three-factor models were tested using baseline data, then confirmed with 12-month data. Model modifications were made based on empirical inspection of baseline data and replicated using 12-month data. Cronbach's alpha and correlations with measures of quality of life and psychological health were examined. RESULTS: All three models had strong factor loadings on all items except the negatively worded items. The two-factor and three-factor models fit reasonably well after modifications, but the single factor did not fit well (1/2/3-factor: RMSEA 0.14/0.09/0.06, CFI 0.85/0.93/0.97, SRMR 0.09/0.05/0.04). Internal consistency was sufficient for all factors. CONCLUSION: The two-factor and three-factor models were supported in heart failure patients. The three-factor model demonstrated better statistical fit but was not more interpretable. KEY MESSAGE: This study investigated the factor structure of the FACIT-Sp in patients with heart failure. The two-factor and three-factor models were supported, but the single factor model was not. Negatively worded items did not perform well.
