This study identified the moderated mediation relationship among age, Internet self-efficacy, and statistics anxiety on student satisfaction after controlling for demographics and technology experiences in research methods courses in a blended professional doctoral program. One hundred and thirty-one students in a three-year Ed.D. Program participated in the study. The results show that after controlling for gender, ethnicity, and technology experiences, age was negatively associated with Internet self-efficacy and Internet self-efficacy mediated the relationship between age and course satisfaction as well. Although the moderation effect of statistics anxiety between self-efficacy and student satisfaction was not supported, there was still partial evidence that the group with statistics anxiety behaved differently from the group without statistics anxiety in terms of the conditional indirect effect of age on course satisfaction. The authors call for future studies to focus on online or blended research courses in professional doctoral programs and test the proposed conceptual model.
