ABSTRACT
OBJECTIVE:
To validate an electronic nutrition literacy assessment tool (e-NutLit).DESIGN:
Cross-sectional.SETTING:
An Australian teaching hospital obesity clinic (clinical cohort) and university (dietetic cohort).PARTICIPANTS:
A convenience sample of patients with obesity (body mass index > 35 kg m-2) (obese participants [OP]) and dietetic interns (DI).INTERVENTIONS:
The e-NutLit was administered to OP and scores were compared with performance on the Newest Vital Sign and e-NutLit scores of the DI to establish construct validity. A subset of OP completed the e-NutLit again to examine instrument temporal stability. Internal consistency was assessed using Cronbach α. MAIN OUTCOMEMEASURES:
Construct validity, temporal stability, and internal consistency.ANALYSIS:
Parametric and nonparametric tests and general linear modeling were used as appropriate.RESULTS:
A total of 103 participants completed the study (OP nâ¯=â¯59; 64.4% female; DI nâ¯=â¯44; 86.4% female). Newest Vital Sign and e-NutLit scores were significantly and positively associated (rsâ¯=â¯0.66; P <.001). The DI performed significantly better than the OP (OP 59.7 ± 13.1 percentage points; DI 83.9⯱â¯5.5 percentage points; P <.001), further supporting construct validity. The e-NutLit Cronbach α was >0.9 indicating a good level of internal consistency. The OP test and retest scores were not significantly different, supporting instrument temporal stability. CONCLUSION AND IMPLICATIONS The results support the validity of the e-NutLit, for both clinicians and researchers.Palavras-chave
