<p>The study investigates factors contributing to the low level of skill in the adoption of quantitative approaches in clinical social work aligned students’ thesis. We collected the data over a five-year period, spanning from 2019 to 2023. The data was collected from a sample of (<i>n</i> = 264) social work students who had completed a Bachelor of Social Work with Honors Degree or a Master of Social Work, all with research topics related to clinical social work. A self-administered questionnaire was used as a research instrument to measure the influence of four major items: attitudes and beliefs, knowledge and skills, institutional factors, and confidence, in predicting the adoption of quantitative approaches in clinical social work aligned students’ thesis. A bivariate Pearson’s correlation analysis showed that knowledge and skills had a moderately negative correlation at ρ &lt; 0.05 with the use of quantitative approaches in social work students’ thesis, while attitudes and beliefs, institutional factors, and confidence had a strong positive correlation (ρ &lt; 0.01). A regression analysis showed that all major dimensions-attitudes and beliefs and knowledge and skills were both statistically significant at (ρ &lt; 0.05), while institutional factors and confidence at ρ &lt; 0.01. The 5th regression model combined all four factors, and the model was statistically significant at ρ &lt; 0.01. The study called for clinical social work education and training to empower students to adopt a positive attitude towards quantitative research, foster a culture of institutional support and collaboration, and enhance students’ confidence in conducting quantitative research.</p>
