Efficacy of a modified digital unified protocol targeting both positive and negative emotion regulation: A randomized clinical trial.
Abstract
The Unified Protocol (UP) has proven effective for treating emotional disorders; however, its standard format primarily focuses on regulating negative emotions. While difficulties with negative emotion regulation are common across these disorders, difficulties with positive emotion regulation are often overlooked. This study evaluated the efficacy of a digitally adapted UP incorporating positive emotion regulation strategies (internet-delivered unified protocol+). In a randomized clinical trial, 120 adults (Mage = 34.0, SD = 12.0; 73% female; 75% White) with principal anxiety, depressive, or obsessive-compulsive disorders were assigned to the internet-delivered unified protocol+ (n = 80) or standard internet-delivered unified protocol (n = 40). Both 12-week programs occurred via an online platform with asynchronous clinical support through weekly messaging. Outcomes included anxiety, depression, and stress; positive/negative affect; functional impairment; savoring; positive mental health; and flourishing. Analyses included between- and within-group effect sizes, remission comparisons, and latent growth modeling. Both groups demonstrated statistically significant reductions in anxiety, depression, stress, negative affect, and functional impairment (standardized mean gain effect size ≈ -0.28 to -1.13) that were maintained across a 3-month follow-up. Statistically significant, small-to-moderate gains in positive mental health and flourishing (standardized mean gain effect size ≈ 0.31-0.37) were also observed and maintained. Positive affect and savoring significantly increased by Week 8 but diminished and were no longer significant at follow-up. No group differences emerged for any outcome. Digital UP interventions were associated with symptom reduction and improvements in flourishing, but adding positive emotion regulation content did not yield incremental benefits. Future research should explore whether increased intensity or duration of these strategies improves outcomes. (PsycInfo Database Record (c) 2026 APA, all rights reserved).
Clinical relevance
Does a digitally delivered, modified Unified Protocol augmented with positive emotion regulation strategies (iUP+) produce superior outcomes compared to a standard internet-delivered Unified Protocol (iUP) in adults with principal anxiety, depressive, or obsessive-compulsive disorders? __SNAPSHOT__ {"studyDesign":"Randomized clinical trial (parallel-group, unequal allocation)","setting":"Online platform; country not reported in abstract; clinical support delivered asynchronously via weekly messaging","sampleSize":"n = 120 (iUP+: n = 80; iUP: n = 40)","population":"Adults (mean age 34.0 years, SD = 12.0; 73% female; 75% White) with a principal diagnosis of an anxiety disorder, depressive disorder, or obsessive-compulsive disorder","intervention":"Internet-delivered Unified Protocol+ (iUP+): a 12-week digitally adapted Unified Protocol incorporating both negative and positive emotion regulation strategies, delivered via online platform with asynchronous weekly clinician messaging","comparator":"Standard internet-delivered Unified Protocol (iUP): a 12-week standard digital UP targeting primarily negative emotion regulation, delivered via the same online platform with asynchronous weekly clinician messaging","primaryOutcome":"Not explicitly labeled as a single primary outcome in the abstract; outcomes assessed included anxiety, depression, and stress; positive and negative affect; functional impairment; savoring; positive mental health; and flourishing.

Key findings
The abstract is truncated and does not provide complete outcome data. Based on the available text, both the iUP+ and the standard iUP groups demonstrated statistically significant reductions in anxiety (and presumably depression and stress, given the sentence structure), but the specific effect sizes, confidence intervals, p-values, between-group comparative statistics, remission rates, and results for positive affect outcomes (savoring, positive mental health, flourishing) are not reported in the provided abstract excerpt. No NNT or NNH can be calculated from the available data. Adverse events are not reported. All quantitative findings beyond the directional statement of within-group significance are not reported.
Practice implications
Based solely on the truncated abstract, both digital delivery formats of the Unified Protocol appear to produce statistically significant symptom reductions in adults with anxiety, depressive, and obsessive-compulsive disorders. Whether the iUP+ confers meaningful additional benefit over the standard iUP — particularly on positive affect outcomes such as savoring, flourishing, and positive mental health — cannot be determined from the available text, as comparative (between-group) results and all secondary outcome data are absent. The population studied was predominantly female (73%) and White (75%), which substantially limits generalizability to men, racial/ethnic minority populations, older adults, and those with severe or treatment-resistant presentations. The theoretical rationale for targeting positive emotion regulation as an overlooked mechanism in emotional disorders is sound and consistent with the broader UP literature, but clinical practice implications cannot be drawn until full between-group data are available. This summary is based on an abstract only; the complete publication should be consulted before applying findings to clinical decision-making. __LIMITATIONS__ Abstract is truncated — the full results section, including between-group comparisons, effect sizes, confidence intervals, p-values, remission rates, and secondary outcome data, are unavailable for review.,Unequal allocation (2:1 iUP+ to iUP) may reduce statistical power for between-group comparisons in the smaller control arm.,Sample is predominantly female (73%) and White (75%), limiting generalizability to diverse populations.,No waitlist or placebo control group; the active comparator design cannot establish superiority over no treatment or treatment as usual.,Asynchronous-only clinician support (weekly messaging) may not reflect real-world clinical practice, where synchronous therapeutic contact is standard.,The online, self-selected recruitment method introduces potential volunteer and selection bias.,Absence of a formal blinding procedure is inherent to psychotherapy trials and cannot be fully mitigated.,Follow-up duration beyond 12 weeks is not reported, leaving durability of gains unknown.,Inclusion of OCD alongside anxiety and depressive disorders may introduce diagnostic heterogeneity that complicates outcome interpretation.,Funding source not reported; potential conflicts of interest cannot be assessed.,The distinction between statistical significance and clinical meaningfulness of symptom changes cannot be evaluated without full effect size and threshold data. __BOTTOM_LINE_CATEGORY__ promising_but_preliminary __BOTTOM_LINE__ Both the augmented iUP+ and the standard iUP produced statistically significant reductions in anxiety in this 12-week randomized trial of adults with emotional disorders, but the truncated abstract precludes any conclusion about whether positive emotion regulation augmentation confers additional benefit. Clinicians should await the full publication — including between-group effect sizes, remission data, and positive affect outcomes — before considering the iUP+ over standard digital UP delivery.
