Validation of a Brief Physical Activity Assessment Tool for Adults With Limited Resources
Objective
To validate a Brief Physical Activity Assessment Tool for the Expanded Food and Nutrition Program (EFNEP).
Design
Phase 1: test-retest reliability based on 2 survey administrations; Phase 2: concurrent validity triangulated with accelerometer data; Phase 3: sensitivity to change and responsiveness and secondary analysis of EFNEP national dataset.
Setting
Community centers and/or EFNEP classes across the US.
Test-retest reliability, concurrent validity, and sensitivity to change and responsiveness.
Analysis
Test-retest reliability: intraclass correlation, κ, and Spearman correlation coefficient (SCC); concurrent validity: SCC; sensitivity to change: standardized response mean, effect size, and paired t tests; responsiveness: minimal important difference.
Results
The Brief Physical Activity Assessment Tool's test-retest results were moderate (intraclass correlation = 0.77–0.84; κ = 0.55–0.61; SCC = 0.59–0.84). Concurrent validity differed by questions but was highest for the muscle-strengthening question (SCC = 0.87). All questions demonstrated moderate sensitivity to change and responsiveness. Patterns between non-Hispanics and Hispanics were similar.
Conclusions and Implications
The study resulted in a brief, validated, nationally tested questionnaire for evaluating physical activity changes for non-Hispanic adults with limited resources, which could be included in short surveys. It could be further validated among other populations.
期刊介绍:
The Journal of Nutrition Education and Behavior (JNEB), the official journal of the Society for Nutrition Education and Behavior, is a refereed, scientific periodical that serves as a global resource for all professionals with an interest in nutrition education; nutrition and physical activity behavior theories and intervention outcomes; complementary and alternative medicine related to nutrition behaviors; food environment; food, nutrition, and physical activity communication strategies including technology; nutrition-related economics; food safety education; and scholarship of learning related to these areas.
The purpose of JNEB is to document and disseminate original research and emerging issues and practices relevant to these areas worldwide. The Journal of Nutrition Education and Behavior welcomes evidence-based manuscripts that provide new insights and useful findings related to nutrition education research, practice and policy. The content areas of JNEB reflect the diverse interests in nutrition and physical activity related to public health, nutritional sciences, education, behavioral economics, family and consumer sciences, and eHealth, including the interests of community-based nutrition-practitioners. As the Society''s official journal, JNEB also includes policy statements, issue perspectives, position papers, and member communications.
