Perceived behavioral control, Intension to use donor human milk, Attitude, Subjective norm


This study was employed to describe level and relationship between attitude, subjective norm, perceived behavioral control, and intention to use donor human milk among mothers. A purposive sample of 220 mothers with newborn admitted in the NICU was recruited. Data were collected using the Attitude, Subjective Norm, Perceived Behavioral Control, and Intention to Use Donor Breast Milk Questionnaire. The content validity of the questionnaire was determined by experts yielding content validity index .95. The Cronbach’s alpha coefficients of the questionnaire was .89. Descriptive statistics were used for data analysis. Pearson's product moment correlation coefficient was examined for correlation between variables.
The results showed that (1) the mothers had positive attitude toward using donor human milk. Subjective norm toward using donor human milk, perceived behavioral control toward using donor human milk, and intention to use donor human milk were at a moderate level, and (2) attitude, subjective norm, and perceived behavioral control had a moderate significant positive correlation with intention to use donor human milk among mothers (r = .38, p < .01; r = .58, p < .01; and r = .36,
p < .01, respectively).
The findings of this study can be used as a guideline to explore strategies to enhance mothers’ positive attitude, subjective norm, and perceived behavioral control toward using donor breast milk, which in turn will increase mothers’ intention to use donor breast milk later.
