Recalling what we thought we knew about recall periods: a qualitative descriptive study of how adults diagnosed with cancer use recall periods for patient-reported outcome items about physical function.

Objectives: In cancer studies, assessment of patients' physical function can provide insight into cancer-related symptoms and the side effects of treatment. Physical function can be assessed using patient-reported outcome measures (PROMs), which may or may not include a recall period-the amount of time the questionnaire asks the respondent to think back to answer the questions. More understanding is needed about how patients interpret and respond to items posed with different recall periods, and which recall period they actually use.

How do patients interpret and respond to a novel patient-reported eastern cooperative oncology group performance status (ECOG)?

Purpose: Performance status is an important concept in oncology, but is typically clinician-reported. Efforts are underway to include patient-reported measures in cancer care, which may improve patient symptoms, quality of life and overall survival. The purpose of this study was to gain a preliminary understanding of how patients determined their physical performance status based on a novel patient-reported version of the Eastern Cooperative Oncology Group Performance Status (ECOG) scale.

What facets of physical function are most important to adults diagnosed with cancer?

Purpose: Successful patient-focused drug development involves selecting and measuring outcomes in clinical trials that are important to patients. The U.S.

Facets of physical function assessed by patient-reported outcome measures in oncology research.

Purpose: The U.S. Food & Drug Administration has identified physical functioning (PF) as a core patient-reported outcome (PRO) in cancer clinical trials.

Health-related quality of life by race, ethnicity, and country of origin among cancer survivors.

Background: Typical cancer research studies of health-related quality of life (HRQOL) in the United States do not include country of origin when examining race and ethnic group differences. This population-based, cross-sectional study used an innovative methodology to examine how self-reported racial and ethnic groups, by country of origin, report differential HRQOL experiences after adjusting for clinical and demographic characteristics, including socioeconomic status.

Methods: Recruited from 4 cancer registries in California, Louisiana, and New Jersey, cancer survivors completed Patient-Reported Outcomes Measurement Information System measures of fatigue, pain interference, anxiety, depression, sleep disturbance, physical function, ability to participate in social roles, and cognitive function.

Investigating gender-based differential item functioning on the Kansas City Cardiomyopathy Questionnaire (KCCQ) using qualitative content analysis.

Purpose: The purpose of this study is to evaluate potential gender-based differences in interpreting the Kansas City Cardiomyopathy Questionnaire (KCCQ-23) and to explore if there are aspects of health-related quality of life (HRQOL) not captured by the KCCQ-23 that are important to assess in men and/or women with heart failure (HF).

Methods: Patients ≥ 22 years of age with clinician-diagnosed HF and left ventricular ejection fraction ≤ 40% were recruited from two academic medical centers to participate in semi-structured concept elicitation and cognitive debriefing interviews. Enrollment was stratified by patient-identified gender (half women/half men).

Do PRO Measures Function the Same Way for all Individuals With Heart Failure?

Women diagnosed with heart failure report worse quality of life than men on patient-reported outcome (PRO) measures. An inherent assumption of PRO measures in heart failure is that women and men interpret questions about quality of life the same way. If this is not the case, the risk then becomes that the PRO scores cannot be used for valid comparison or to combine outcomes by subgroups of the population.

Psychometric Evaluation of the Kansas City Cardiomyopathy Questionnaire in Men and Women With Heart Failure.

Background: The Kansas City Cardiomyopathy Questionnaire (KCCQ) has been psychometrically evaluated in multiple heart failure (HF) populations, but the comparability of its psychometric properties between men and women is unknown.

Methods: Data from 3 clinical trials (1 in stable HF with preserved ejection fraction, 1 each in stable and acute HF with reduced ejection fraction) and 1 prospective cohort study (stable HF with reduced ejection fraction), incorporating 6773 men and 3612 women with HF, were used to compare the construct validity, internal and test-retest reliability, ability to detect change, predict mortality and hospitalizations and minimally important differences between the 2 sexes. Interactions of the KCCQ overall summary and subdomain scores by sex were independently examined.

Association Between Public Knowledge About COVID-19, Trust in Information Sources, and Adherence to Social Distancing: Cross-Sectional Survey.

Background: The success of behavioral interventions and policies designed to reduce the impact of the COVID-19 pandemic depends on how well individuals are informed about both the consequences of infection and the steps that should be taken to reduce the impact of the disease.

Objective: The aim of this study was to investigate associations between public knowledge about COVID-19, adherence to social distancing, and public trust in government information sources (eg, the US Centers for Disease Control and Prevention), private sources (eg, FOX and CNN), and social networks (eg, Facebook and Twitter) to inform future policies related to critical information distribution.

Methods: We conducted a cross-sectional survey (N=1243) between April 10 and 14, 2020.
