A Smartphone Application to Support Recovery From Alcoholism: A Randomized Clinical Trial
Open accessAbstract
IMPORTANCE: Patients leaving residential treatment for alcohol use disorders are not typically offered evidence-based continuing care, although research suggests that continuing care is associated with better outcomes. A smartphone-based application could provide effective continuing care. OBJECTIVE: To determine whether patients leaving residential treatment for alcohol use disorders with a smartphone application to support recovery have fewer risky drinking days than control patients. DESIGN, SETTING, AND PARTICIPANTS: An unmasked randomized clinical trial involving 3 residential programs operated by 1 nonprofit treatment organization in the Midwestern United States and 2 residential programs operated by 1 nonprofit organization in the Northeastern United States. In total, 349 patients who met the criteria for DSM-IV alcohol dependence when they entered residential treatment were randomized to treatment as usual (n = 179) or treatment as usual plus a smartphone (n = 170) with the Addiction-Comprehensive Health Enhancement Support System (A-CHESS), an application designed to improve continuing care for alcohol use disorders. INTERVENTIONS: Treatment as usual varied across programs; none offered patients coordinated continuing care after discharge. A-CHESS provides monitoring, information, communication, and support services to patients, including ways for patients and counselors to stay in contact. The intervention and follow-up period lasted 8 and 4 months, respectively. MAIN OUTCOMES AND MEASURES: Risky drinking days--the number of days during which a patient's drinking in a 2-hour period exceeded 4 standard drinks for men and 3 standard drinks for women, with standard drink defined as one that contains roughly 14 g of pure alcohol (12 oz of regular beer, 5 oz of wine, or 1.5 oz of distilled spirits). Patients were asked to report their risky drinking days in the previous 30 days on surveys taken 4, 8, and 12 months after discharge from residential treatment. RESULTS: For the 8 months of the intervention and 4 months of follow-up, patients in the A-CHESS group reported significantly fewer risky drinking days than did patients in the control group, with a mean of 1.39 vs 2.75 days (mean difference, 1.37; 95% CI, 0.46-2.27; P = .003). CONCLUSIONS AND RELEVANCE: The findings suggest that a multifeatured smartphone application may have significant benefit to patients in continuing care for alcohol use disorders. TRIAL REGISTRATION: clinicaltrials.gov Identifier: NCT01003119.

What the paper did — it cites no source for this, so there is none to check. The quote shows it is in the paper.
In the paper
“The study involved only 2 treatment organizations and 5 programs, and most patients were white males in their 30s and 40s.”

A conclusion the paper draws from its own results — it cites no other source for it, so there is none to check. The quote shows it is in the paper.
In the paper
“The promising results of this trial in continuing care for AUDs point to the possible value of a smartphone intervention for treating AUDs and perhaps other chronic illnesses.”

The paper relies on this without support.
No other large randomized trial has been reported about the effectiveness of mobile technology for continuing care of AUDs.
“To our knowledge, no other large randomized trial has been reported about the effectiveness of mobile technology for the continuing care of AUDs.”
The paper relies on this without support.
The missing outcome data in this trial are missing at random.
“provide unbiased estimates when data are missing at random.”
The paper relies on this without support.
The modified 8-item set derived from the SIP-R adequately captures negative consequences of drinking.
“Because of these departures from the established instrument, the 8 items were examined individually rather than as a single scale.”
Claims other papers make about this one
Each is checked against this paper’s own text: does it say what the citing paper says it does?
The source backs part of the claim, not all of it — or backs it for a different population, condition or comparison.
In the citing paper
“researchers using an application designed to provide support to people with alcoholism (Addiction—Comprehensive Health Enhancement Support System or A-CHESS) were able to partially predict the number of days of consumption based on the level of use of the application by the user (i.e., number of times spent on the application, number of pages viewed) (104).”

Self-check
Percentages, sums and reported differences re-computed from the paper’s own numbers.
Each contradiction between two passages listed here was confirmed by an independent check.
A-CHESS randomization count conflicts with the group totals
MinorThe results say 179 patients were assigned to A-CHESS, while the abstract assigns 179 to control and 170 to treatment.
“Although 179 patients were randomized to the A-CHESS group”
“179 were randomized to the control group and 170 to the treatment group.”
Pages-viewed estimate falls outside its confidence interval
MinorThe reported coefficient is positive, but both confidence-interval bounds are negative.
“per 100 pages: B = 0.036”
“95% CI [−0.069, −0.002)”
Replacement reasons exceed the stated total
MinorThe four listed replacement counts sum to 117, rather than the stated 113.
Reported 113 · recomputed 117
“113 phones were replaced: 56 did not work properly, 19 were stolen, 20 were damaged by patients, and 22 were lost.”
Mediation estimate falls outside its confidence interval
MinorThe reported path-b estimate is −0.969, but its interval runs from positive 1.650 to −0.289 and does not contain that estimate.
“b: −.969”
“[1.650, −.289]”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
A language model drew the claims from the paper on 2026-10-06, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).
A second model labelled each claim on 2026-10-06 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
