Rural and Urban Variation in Mobile Health Substance Use Disorder Treatment Mechanisms and Efficacy.
Article in Rural mental health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Residents of rural areas face significant barriers to substance use disorder (SUD) treatment, including poor access, stigma, lack of confidentiality, and distrust of mental health services, which may inhibit treatment engagement. Mobile health (mHealth) approaches offer personalized, private, and easily accessible SUD treatment for rural residents, but differences in treatment mechanisms and efficacy across rural and urban regions are unknown. The present study investigates rural versus urban differences in the efficacy an mHealth SUD treatment via the theorized treatment mechanisms: protective behavioral strategies, readiness to change, and peer network health. The study leverages the results of a randomized clinical trial of an mHealth SUD treatment called Peer Network Counseling-txt (PNC-txt) conducted among a sample of young adults (age 18-25) with cannabis use disorder (CUD). We hypothesize that the impact of PNC-txt treatment on the treatment mechanisms will be stronger in rural, as compared to urban, regions, consequently leading to significantly greater reductions in cannabis use among rural residents. Results indicate that while PNC-txt reduces past 30-day cannabis use at 6 months via 1-month increases in both protective behavioral strategies and readiness to change, these indirect effects of treatment do not differ significantly between rural and urban residents. Our findings suggest that readiness to change and protective behavioral strategies are effective treatment targets for reducing the frequency of young adult cannabis use and support mHealth as an important SUD treatment approach for addressing treatment barriers in rural regions.
