The field of applied linguistics is becoming increasingly transdisciplinary as recognition for the need to approach empirical questions from a variety of epistemological and theoretical perspectives grows (Douglas Fir Group, 2016). One methodological approach that holds promise for advancing sophisticated inquiry into complex issues of applied linguistics is mixed methods research (MMR); however, studies adopting MMR to its fullest potential remain infrequent. Employing an exploratory sequential mixed methods design that includes a focus group and survey questionnaire, this empirical study investigates the internal and external factors that may lead applied linguistics researchers to avoid conducting and/or publishing MMR. Integrated analyses revealed that participants' methodological and publishing decisions were influenced by factors such as their socialization into research practices in graduate school, the pressure to publish, and the considerations of the research journal industry. Implications for future applied linguistics researcher education programs and the impact of the publishing industry on research agendas are discussed.
