The study examined the relationship between perceived usefulness of smartphones and parenting practices in Mende Sub-County, Wakiso District, Uganda. The research employed a cross-sectional survey design, collecting data from 205 parent respondents through structured questionnaires. Data were analyzed using descriptive and inferential statistics including Pearson correlation and simple linear regression analysis. The findings revealed a strong positive relationship between perceived usefulness of smartphones and parenting practices (r = 0.68, p < 0.01). Parents' perception of smartphones as helpful tools for coordination with schools demonstrated the highest mean score (M = 4.25, SD = 0.88), followed by improved school-parent communication (M = 4.20, SD = 0.91) and enhanced parental involvement (M = 4.15, SD = 0.92). Regression analysis indicated that perceived usefulness explained 46% of the variance in parenting practices (R² = 0.46, β = 0.68, t = 9.00, p < 0.001). The unstandardized coefficient (B= 0.72) demonstrated that for every one-unit increase in perceived usefulness, parenting practice scores increased by 0.72 units. Overall, 82.4% of parents perceived smartphones as useful tools for supporting parenting responsibilities, while variations in digital literacy influenced the degree of benefit realized. Perceived usefulness of smartphones significantly influenced parenting practices in Mende Sub-County. Parents who recognized smartphones as beneficial tools demonstrated more active monitoring, effective communication with schools, and supportive parenting behaviors. The Technology Acceptance Model was validated, confirming that perceived usefulness constituted a primary driver of technology adoption and application in parenting contexts.The study recommended implementing digital literacy training programs for parents focusing on educational applications and monitoring tools, establishing school-parent communication platforms that leveraged smartphone capabilities, developing contextually appropriate parenting applications addressing local needs, conducting awareness campaigns highlighting smartphone benefits for child development, providing technical support services assisting parents in utilizing educational technologies, creating parent peer support groups facilitating knowledge sharing about effective smartphone use, partnering with telecommunications companies to offer subsidized data packages for educational purposes, and integrating digital parenting education into community development programs.
