Knowledge, Attitude, Subjective Norm, Perceived Behavioral Control, Intention to Donate Breast Milk, Human Milk BankAbstract
This descriptive study aimed to examine the relationships among knowledge, attitude, subjective norms, perceived behavioral control, and intention to donate breast milk to the human milk bank. A purposive sample of 255 postpartum women were recruited at a hospital in Southern Thailand between August and November 2020. Data were collected using a questionnaire including: 1) knowledge regarding breast milk donation, 2) attitude towards breast milk donation, 3) subjective norms, 4) perceived behavioral control, and 5) intention to donate breast milk to the Human Milk Bank in Southern Thailand. Content validity of the questionnaire was examined by experts, obtaining a value of 1.0. In terms of knowledge regarding breast milk donation, the reliability of the questionnaire was tested using Kuder Richardson (KR-20), yielding a value of .71. The attitudes, subjective norms, perceived behavioral control, and intention to donate breast milk to the Human Milk Bank questionnaire were tested with Cronbach’s alpha coefficient, yielding a value of .95, knowledge regarding breast milk donation, attitude towards breast milk donation, subjective norms and perceived behavioral control yielding a value of .80, .94 and .90 respectively. Data were analysed using descriptive statistics, and Spearman's rank correlation.
The results showed that 54% of subjects had a moderate level of knowledge regarding breast milk donation. Subjects had a positive attitude towards breast milk donation to the human milk bank (M=32.50, SD=5.40). The mean score for subjective norm was a high level (M=33.16, SD=9.01). The mean score for perceived behavioral control to donate breast milk to the human milk bank was at a moderate level (M=35.27, SD=8.16). Seventy-two percent of subjects had a high level of intention to donate breast milk to the human milk bank. Knowledge regarding breast milk donation had no significant correlation with the intention to donate breast milk to the Human Milk Bank (rs=.08, p=.22). Attitudes, subjective norms, and perceived behavioral control had a moderate significant positive correlation with the intention to donate breast milk to the human milk bank (rs=.47; rs=.49 and rs=.42, p<.01 respectively).
The results of this study can be used to enhance the intention to donate breast milk to the human milk bank among postpartum women who have excess milk supply by promoting a positive attitude, increasing subjective norm, and perceived behavioral control.
