In this study, we aim evaluate reliability, internal consistency preliminary construct validity newly developed Dietary Intention Evaluation Tool In-hospital patients (DIETI) which based on TPB.An expert panel constructed item list DIETI. A total 312 admitted cardiology ward filled out Explanatory- confirmatory factor analysis showed that our adequately discerns five TPB-consistent factors regarding healthy diet hospitalized patients. (N = 312, CFA model χ2 313.072 (df 160, p < 0.001, CFI 0.939, RMSEA 0.058). Subsequent reliability satisfactory strong questionnaire as whole all subscales (Cronbach's alpha ranging between 0.65 0.88).We conclude DIETI an internally reliable behavioral intentions in-hospital Thus, can be aimed at
