Abstract
Objective
To examine the mediating effects of food resource management skills (FRM) on the relationship
between participation in a Supplemental Nutrition Assistance Program Education (SNAP-Ed) nutrition education program and diet quality.
Design
Secondary analysis of data from a propensity score-matched sample of participants
(n = 396) and nonparticipants (n = 111) in a SNAP-Ed nutrition education program.
Analysis
Independent-samples t tests were used to compare entry, exit, and gain scores in FRM
and diet quality between participants and nonparticipants. Structural equation modeling
was used to examine direct and mediated relationships among participation, FRM, and
diet quality.
Main Outcome Measures
Food resource management was measured as a summated rating scale, and diet quality
measured as Healthy Eating Index and program participation.
Results
Mediated effect of FRM on the relationship between participation in a SNAP-Ed program
and diet quality was statistically significant (P < 0.01). The effect size for the mediation effect indicated that about 70% of program
participation on diet quality was transferred by FRM skills. The hypothesized model
had acceptable fit indices as model χ2 was nonsignificant (P = 0.31), all fit indices were above 0.9, and the root mean square of error approximation
was low at 0.02.
Conclusions and Implications
Participation in a SNAP-Ed program enhanced participants’ FRM, which in turn enhanced
their diet quality.
