ConclusionsĪutomated SMS systems offer a feasible and acceptable means of monitoring depression within clinical research. Overall, the single item SMS scale also appeared more responsive to changes in depression, resulting from treatment, than the PHQ-9. SMS depression scores over the 15 weeks differed significantly between trial arms (p = 0.007), with participants allocated to the acupuncture and counselling arms reporting improved depression outcomes compared to usual GP care alone, which reached statistical significance ten weeks after randomisation. Comparison of PHQ-9 and SMS responses at 3 months demonstrated a moderate to high degree of agreement (Kendall’s tau-b = 0.57, p < 0.0001, n = 220). The automated SMS system was quick to set-up, inexpensive, and well received. Invalid responses accounted for 1.1% of texts. Participants provided a valid response to an average of 12.5 messages. Resultsĥ27 (69.8%) trial participants consented to the texting sub-study, of whom 498 (94.5%) responded to at least one message. SMS responses were compared between groups over time to explore treatment effects. Concurrent validity was estimated by correlating SMS responses with the Patient Health Questionnaire (PHQ-9). Feasibility and acceptability of the automated SMS system were evaluated according to cost, ease of implementation, proportion consenting, response rates, and qualitative feedback. ![]() Texts were a single question asking, on a scale from 1 to 9, the extent to which they felt depressed. ![]() Two weeks following random allocation, trial participants were sent a weekly text message for 15 weeks. Methodsħ55 depressed patients (BDI-II score ≥20) were recruited from primary care into a randomised trial of acupuncture versus counselling or usual care, and invited to opt into a repeated-measures text messaging sub-study. This paper reports on the development, feasibility, acceptability, validity, and discriminant utility of a single item depression rating scale, delivered weekly via an automated SMS system, as part of a large randomised controlled trial. Despite widespread popularity, text messaging has rarely been used for data collection in clinical research. ![]()
