A Corpus Linguistics Study of Text Message Interventions in Substance Use Disorder Treatment

Technology is being leveraged in numerous ways to improve client care. Health-related text messages aim to engage clients, assure treatment session attendance, and promote healthy habits. Research on the use of text messages in substance use disorder treatment demonstrates the efficacy of this intervention; however, research is lacking related to the linguistic composition of provider text messages. Text messages interventions were collected from previously published research on the treatment of substance use disorders. A corpus of 71 text messages was composed totaling 1,624 words. Using Linguistic Inquiry and Word Count software (LIWC), the corpora of text messages were examined for use of terminology thought to enhance client engagement. Results demonstrated statistical significance of six LIWC measures when compared against national blog norms (i.e., Twitter). Clout, a score that demonstrates writer expertise and confidence was higher than expected when compared to national norms, while Authenticity, writing that is both honest and personal in nature, was found to be significantly lower than expected. The Emotional Tone of text message communications from substance use disorder treatment providers was found to be neutral. The use of Biological terms and Leisure words were found to be more prevalent in substance use disorder treatment text messages than national norms. Informal terminology, however, was used at a lesser rate than expected.
