In a recent study, researchers aimed to identify early indicators of who will remain in or leave treatment for substance use disorder (SUD) by analyzing linguistic markers in patients' Facebook posts before they entered a SUD treatment program.
By utilizing machine learning models known to have social-psychology relevance, the researchers extracted and analyzed linguistic features from participants' Facebook posts (N = 206, 39.32% female; 55,415 postings) over the two years before treatment entry. The features from theoretical domains of religiosity, affect, and temporal orientation via established AI-based linguistic models were also used.
Results showed that patients who stayed in SUD treatment for over 90 days used more words associated with religion, positive emotions, family, affiliations, and the present, and used more first-person singular pronouns. Patients who discontinued their treatment before 90 days discussed more diverse topics, focused on the past, and used more articles. These findings confirm the literature on protective and risk social-psychological factors linking to SUD treatment in language analysis, highlighting the importance of taking these linguistic features and markers into consideration when designing and recommending SUD treatment plans.
