Population-level administrative data: A resource to advance psychological science.

Population-level administrative data-data on individuals' interactions with administrative systems, such as healthcare, social-welfare, criminal-justice, and education systems-are a fruitful resource for research into behavior, development, and wellbeing. However, administrative data are underutilized in psychological science. Here, we review advantages of population-level administrative data for psychological research, with examples of advances in psychological theory arising from administrative-data studies.

Perceptions of Multicancer Detection Tests Among Primary Care Physicians and Laypersons: A Qualitative Study.

Introduction: Multicancer detection tests (MCDs) are blood-based tests designed to detect multiple cancer types. It is currently unclear whether these cancer screening tests improve mortality. To understand awareness of MCDs among providers and patients, as well as explore how they perceive the benefits, harms, and acceptability of MCDs, we have undertaken a focus group study in primary care physicians (PCPs) and laypersons to explore knowledge, attitudes, and expectations of cancer screening using MCDs.

Primary care physicians and laypersons' perceptions of multicancer detection clinical trial designs.

Background: The National Cancer Institute Cancer Screening Research Network is launching a pilot study (Vanguard) to determine feasibility of successful completion of a clinical trial of multicancer detection tests. This focus group study reports perceptions of primary care physicians and laypersons of different clinical trial designs and willingness to participate in a multicancer detection clinical trial.

Methods: We undertook 14 focus groups with 88 laypersons and 6 focus groups with 45 primary care physicians.
