Understanding patterns of real-world usage of mental health apps is key to maximizing their potential to increase public self-management of care. Although developer-led studies have published results ...on the use of mental health apps in real-world settings, no study yet has systematically examined usage patterns of a large sample of mental health apps relying on independently collected data.
Our aim is to present real-world objective data on user engagement with popular mental health apps.
A systematic engine search was conducted using Google Play to identify Android apps with 10,000 installs or more targeting anxiety, depression, or emotional well-being. Coding of apps included primary incorporated techniques and mental health focus. Behavioral data on real-world usage were obtained from a panel that provides aggregated nonpersonal information on user engagement with mobile apps.
In total, 93 apps met the inclusion criteria (installs: median 100,000, IQR 90,000). The median percentage of daily active users (open rate) was 4.0% (IQR 4.7%) with a difference between trackers (median 6.3%, IQR 10.2%) and peer-support apps (median 17.0%) versus breathing exercise apps (median 1.6%, IQR 1.6%; all z≥3.42, all P<.001). Among active users, daily minutes of use were significantly higher for mindfulness/meditation (median 21.47, IQR 15.00) and peer support (median 35.08, n=2) apps than for apps incorporating other techniques (tracker, breathing exercise, psychoeducation: medians range 3.53-8.32; all z≥2.11, all P<.05). The medians of app 15-day and 30-day retention rates were 3.9% (IQR 10.3%) and 3.3% (IQR 6.2%), respectively. On day 30, peer support (median 8.9%, n=2), mindfulness/meditation (median 4.7%, IQR 6.2%), and tracker apps (median 6.1%, IQR 20.4%) had significantly higher retention rates than breathing exercise apps (median 0.0%, IQR 0.0%; all z≥2.18, all P≤.04). The pattern of daily use presented a descriptive peak toward the evening for apps incorporating most techniques (tracker, psychoeducation, and peer support) except mindfulness/meditation, which exhibited two peaks (morning and night).
Although the number of app installs and daily active minutes of use may seem high, only a small portion of users actually used the apps for a long period of time. More studies using different datasets are needed to understand this phenomenon and the ways in which users self-manage their condition in real-world settings.
Outcomes of psychotic disorders are associated with high personal, familiar, societal and clinical burden. There is thus an urgent clinical and societal need for improving those outcomes. Recent ...advances in research knowledge have opened new opportunities for ameliorating outcomes of psychosis during its early clinical stages. This paper critically reviews these opportunities, summarizing the state‐of‐the‐art knowledge and focusing on recent discoveries and future avenues for first episode research and clinical interventions. Candidate targets for primary universal prevention of psychosis at the population level are discussed. Potentials offered by primary selective prevention in asymptomatic subgroups (stage 0) are presented. Achievements of primary selected prevention in individuals at clinical high risk for psychosis (stage 1) are summarized, along with challenges and limitations of its implementation in clinical practice. Early intervention and secondary prevention strategies at the time of a first episode of psychosis (stage 2) are critically discussed, with a particular focus on minimizing the duration of untreated psychosis, improving treatment response, increasing patients’ satisfaction with treatment, reducing illicit substance abuse and preventing relapses. Early intervention and tertiary prevention strategies at the time of an incomplete recovery (stage 3) are further discussed, in particular with respect to addressing treatment resistance, improving well‐being and social skills with reduction of burden on the family, treatment of comorbid substance use, and prevention of multiple relapses and disease progression. In conclusion, to improve outcomes of a complex, heterogeneous syndrome such as psychosis, it is necessary to globally adopt complex models integrating a clinical staging framework and coordinated specialty care programmes that offer pre‐emptive interventions to high‐risk groups identified across the early stages of the disorder. Only a systematic implementation of these models of care in the national health care systems will render these strategies accessible to the 23 million people worldwide suffering from the most severe psychiatric disorders.

All currently available antipsychotics work via essentially the same mechanism: by antagonizing the dopamine D2 receptor. However, schizophrenia is an extremely heterogeneous condition, and antipsychotics do not adequately control symptoms for all patients. Negative and cognitive symptoms are especially difficult to manage with existing medications. Therefore, antipsychotic agents with novel mechanisms of action are urgently needed. Recently, a phase 2 clinical trial and extension study demonstrated that, relative to placebo, the trace amine-associated receptor 1 (TAAR1) agonist ulotaront was effective at controlling the positive, negative, and cognitive symptoms of schizophrenia. In addition, ulotaront seems to lack the weight gain, metabolic issues, and extrapyramidal symptoms associated with traditional antipsychotics. This agent is currently undergoing multiple phase 3 trials for the treatment of schizophrenia. Another TAAR1 agonist, ralmitaront, is being investigated for the treatment of schizophrenia and schizoaffective disorders. Two phase 2 clinical trials are underway, evaluating ralmitaront both as a monotherapy and an add-on therapy to traditional antipsychotics. In this supplement, we review the biologic, preclinical, and clinical data available for TAAR1 agonists, so that if and when they are approved for the treatment of schizophrenia, psychiatry specialists will be ready to use them to optimize patient outcomes. We also briefly review other emerging therapies in late-stage development for the treatment of schizophrenia.
Acute and long-term objectives must be linked early in the treatment of schizophrenia. Maintenance therapy is pivotal in relapse prevention. Relapses are serious events that alter disease trajectory ...and are most often related to nonadherence. Patients with schizophrenia have a substantial risk of relapse, especially when they are nonadherent to antipsychotics. Because relapses are accompanied by structural brain changes, worsening symptoms, and increased treatment resistance when medication is resumed, clinicians must monitor nonadherence and offer strategies to avoid or improve it. Long-acting injectable (LAI) antipsychotics have the potential to reduce nonadherence, relapse, rehospitalization, and mortality, even among patients with first-episode schizophrenia and with comorbid substance use disorder. Long-acting formulations can be a very powerful strategy in helping to ensure that patients get the benefit of the medication they have been prescribed, as the use of LAIs is more easily monitored than oral medications due to the nature of their administration to patients. However, prescribers tend to believe that patients have negative attitudes about LAIs and avoid prescribing them. Patients should be offered the option of LAI antipsychotic treatment and should understand the logistics and the potential benefits of the regimen. LAIs differ regarding their initiation strategy, duration, and flexibility of injection intervals, in addition to the differences of the antipsychotic that the LAI formulation is based on. Presentation matters for LAI treatments to be accepted by patients and family members. Clinicians can use certain communication tools to improve their dialogue with patients about the benefits of switching from oral agents.
Abstract Objective Non-adherence is a major problem in the treatment of schizophrenia. Depot antipsychotic drugs are thought to reduce relapse rates by improving adherence, but a systematic review of ...long-term studies in outpatients is not available. Method We searched the Cochrane Schizophrenia Group's register, ClinicalTrials.gov, Cochrane reviews on depot medication, and the reference sections of included studies for randomised controlled trials lasting at least 12 months in outpatients that compared depot with oral antipsychotics in schizophrenia. Data on relapse (primary outcome), rehospitalisation, non-adherence, and dropout due to any reason, inefficacy of treatment and adverse events were summarised in a meta-analysis using a random-effects model. Study quality was assessed with the Cochrane collaboration's risk of bias tool, and publication bias with funnel plots. Results Ten studies with 1700 participants met the inclusion criteria. Depot formulations significantly reduced relapses with relative and absolute risk reductions of 30% and 10%, respectively (RR 0.70, CI 0.57–0.87, NNT 10, CI 6–25, P = 0.0009), and dropout due to inefficacy (RR 0.71, CI 0.57–0.89). Limited data on non-adherence, rehospitalisation and dropout due to any reason and adverse events revealed no significant differences. There were several potential sources of bias such as limited information on randomisation methods, problems of blinding and different medications in the depot and oral groups. Other studies reduced a potential superiority of depot by excluding non-adherent patients. Discussion Depot antipsychotic drugs significantly reduced relapse. Due to a number of methodological problems in the single trials the evidence is, nonetheless, subject to possible bias.
The literature suggests that the product design of self-guided electronic health (eHealth) interventions impacts user engagement. Traditional trial settings, however, do not enable the examination of ...these relationships in real-world use.
This study aimed to examine whether the qualities of product design, research evidence, and publicly available data predict real-world user engagement with mobile and Web-based self-guided eHealth interventions.
This analysis included self-guided mobile and Web-based eHealth interventions available to the public-with their qualities assessed using the Enlight suite of scales. Scales included Usability, Visual Design, User Engagement, Content, Therapeutic Persuasiveness, Therapeutic Alliance, Credibility, and Research Evidence. Behavioral data on real-world usage were obtained from a panel that provides aggregated nonpersonal information on user engagement with websites and mobile apps, based on a time window of 18 months that was set between November 1, 2016 and April 30, 2018. Real-world user engagement variables included average usage time (for both mobile apps and websites) and mobile app user retention 30 days after download.
The analysis included 52 mobile apps (downloads median 38,600; interquartile range IQR 116,000) and 32 websites (monthly unique visitors median 5689; IQR 30,038). Results point to moderate correlations between Therapeutic Persuasiveness, Therapeutic Alliance, and the 3 user engagement variables (.31≤rs≤.51; Ps≤.03). Visual Design, User Engagement, and Content demonstrated similar degrees of correlation with mobile app engagement variables (.25≤rs≤.49; Ps≤.04) but not with average usage time of Web-based interventions. Positive correlations were also found between the number of reviews on Google Play and average app usage time (r=.58; P<.001) and user retention after 30 days (r=.23; P=.049). Although several product quality ratings were positively correlated with research evidence, the latter was not significantly correlated with real-world user engagement. Hierarchical stepwise regression analysis revealed that either Therapeutic Persuasiveness or Therapeutic Alliance explained 15% to 26% of user engagement variance. Data on Google Play (number of reviews) explained 15% of the variance of mobile app usage time above Enlight ratings; however, publicly available data did not significantly contribute to explaining the variance of the other 2 user-engagement variables.
Results indicate that the qualities of product design predict real-world user engagement with eHealth interventions. The use of real-world behavioral datasets is a novel way to learn about user behaviors, creating new avenues for eHealth intervention research.
Treatment-resistant schizophrenia (TRS) occurs in approximately 30% of individuals diagnosed with schizophrenia. The identification and management of TRS in clinical practice are inconsistent and not ...evidence based. No established clinically relevant criteria for defining and treating TRS exist, although guidelines have been promulgated for clozapine use among TRS patients. This report summarizes the consensus from a roundtable that focused on defining and identifying TRS, pathways to treatment resistance, current treatments, unmet needs, and disease burden. Nine clinical experts in schizophrenia and TRS participated in a closed meeting on June 23, 2017, sponsored by Lundbeck, at which published literature in key areas of TRS research was reviewed. The findings from published studies were synthesized by experts in each area and presented to the group for review and discussion. It was agreed that inadequate response to 2 different antipsychotics, each taken with adequate dose and duration, is required to establish TRS. This recommendation is consistent with guidelines for clozapine use. For each trial, objective symptom measures should be used to assess treatment response, with medication adherence ensured. Once nonresponse is established (after ≥ 12 weeks for positive symptoms 2 trials of ≥ 6 weeks), the treatment plan should be reevaluated and alternative pharmacologic or nonpharmacologic treatments considered. With increased awareness, those involved in the care of patients with schizophrenia will be able to identify TRS earlier in its course, thus supporting more informed treatment decisions by clinicians, patients, and caregivers to reduce the overall disease burden.
While long-acting injectable antipsychotics (LAIs) are hoped to reduce high relapse rates in schizophrenia, recent randomized controlled trials (RCTs) challenged the benefits of LAIs over oral ...antipsychotics (OAPs).
Systematic review/meta-analysis of RCTs that lasted ≥ 6 months comparing LAIs and OAPs. Primary outcome was study-defined relapse at the longest time point; secondary outcomes included relapse at 3, 6, 12, 18, and 24 months, all-cause discontinuation, discontinuation due to adverse events, drug inefficacy (ie, relapse + discontinuation due to inefficacy), hospitalization, and nonadherence.
Across 21 RCTs (n = 5176), LAIs were similar to OAPs for relapse prevention at the longest time point (studies = 21, n = 4950, relative risk RR = 0.93, 95% confidence interval CI: 0.80-1.08, P = .35). The finding was confirmed restricting the analysis to outpatient studies lasting ≥ 1 year (studies = 12, RR = 0.93, 95% CI:0.71-1.07, P = .31). However, studies using first-generation antipsychotic (FGA)-LAIs (studies = 10, RR = 0.82, 95% CI:0.69-0.97, P = .02) and those published ≤ 1991 (consisting exclusively of all 8 fluphenazine-LAI studies; RR = 0.79, 95% CI: 0.65-0.96, P = 0.02) were superior to OAPs regarding the primary outcome. Pooled LAIs also did not separate from OAPs regarding any secondary outcomes. Again, studies using FGA-LAIs and those published ≤ 1991 were associated with LAI superiority over OAPs, eg, hospitalization and drug inefficacy.
In RCTs, which are less representative of real-world patients than naturalistic studies, pooled LAIs did not reduce relapse compared with OAPs in schizophrenia patients. The exceptions were FGA-LAIs, mostly consisting of fluphenazine-LAI studies, which were all conducted through 1991. Because this finding is vulnerable to a cohort bias, studies comparing FGA-LAI vs second-generation antipsychotics-LAI and LAI vs OAP RCTs in real-world patients are needed.
The long‐term benefit‐to‐risk ratio of sustained antipsychotic treatment for schizophrenia has recently been questioned. In this paper, we critically examine the literature on the long‐term efficacy ...and effectiveness of this treatment. We also review the evidence on the undesired effects, the impact on physical morbidity and mortality, as well as the neurobiological correlates of chronic exposure to antipsychotics. Finally, we summarize factors that affect the risk‐benefit ratio. There is consistent evidence supporting the efficacy of antipsychotics in the short term and mid term following stabilization of acute psychotic symptoms. There is insufficient evidence supporting the notion that this effect changes in the long term. Most, but not all, of the long‐term cohort studies find a decrease in efficacy during chronic treatment with antipsychotics. However, these results are inconclusive, given the extensive risk of bias, including increasing non‐adherence. On the other hand, long‐term studies based on national registries, which have lower risk of bias, find an advantage in terms of effectiveness during sustained antipsychotic treatment. Sustained antipsychotic treatment has been also consistently associated with lower mortality in people with schizophrenia compared to no antipsychotic treatment. Nevertheless, chronic antipsychotic use is associated with metabolic disturbance and tardive dyskinesia. The latter is the clearest undesired clinical consequence of brain functioning as a potential result of chronic antipsychotic exposure, likely from dopaminergic hypersensitivity, without otherwise clear evidence of other irreversible neurobiological changes. Adjunctive psychosocial interventions seem critical for achieving recovery. However, overall, the current literature does not support the safe reduction of antipsychotic dosages by 50% or more in stabilized individuals receiving adjunctive psychosocial interventions. In conclusion, the critical appraisal of the literature indicates that, although chronic antipsychotic use can be associated with undesirable neurologic and metabolic side effects, the evidence supporting its long‐term efficacy and effectiveness, including impact on life expectancy, outweighs the evidence against this practice, overall indicating a favorable benefit‐to‐risk ratio. However, the finding that a minority of individuals diagnosed initially with schizophrenia appear to be relapse free for long periods, despite absence of sustained antipsychotic treatment, calls for further research on patient‐level predictors of positive outcomes in people with an initial psychotic presentation.
Comparison of tardive dyskinesia (TD) prevalence during contemporaneous treatment with first-generation antipsychotics (FGAs) and/or second-generation antipsychotics (SGAs).
PubMed/MEDLINE/Google ...Scholar search (January 1, 2000-September 30, 2015) without language restriction using (tardive dyskinesia OR tardive) AND (antipsychotic*) plus specific names of SGAs.
Of 8,895 hits, we screened 203 full-text articles for cross-sectional, rating scale-based TD rates during SGA, FGA, or FGA+SGA treatment. Forty-one studies were used for random effects meta-analysis and meta-regression.
Two authors independently extracted data on overall and antipsychotic class-wise TD rates and on TD moderators.
The global mean TD prevalence was 25.3% (95% CI = 22.7%-28.1%) across all 41 studies (N = 11,493, mean age = 42.8 years, male = 66.4%, schizophrenia-spectrum disorders = 77.1%). TD prevalence varied greatly: Rates were lower with current SGA treatment (20.7%; 95% CI = 16.6%-25.4%, N = 5,103) vs current FGA treatment (30.0%; 95% CI = 26.4%-33.8%, N = 5,062; Q = 9.17, P = .002). This difference remained significant after controlling for moderators: higher age (Z = 2.85, P = .004; number of studies = 39 ) and region (39 studies; Asia vs Europe, Z = 1.55, P = .12; Asia lower than United States, Z = 2.6, P = .009; Asia lower than other regions, Z = 2.42, P = .015). Additional moderators of TD prevalence included longer illness duration (R² = 0.15; P = .03; 21 studies) and frequency of parkinsonism (R² = 0.23, P = .017; number of studies = 19). Particularly low TD prevalence (7.2%; number of studies = 4) was found in the treatment arms with FGA-naive subjects relative to SGA-treated cohorts with likely prior FGA exposure (23.4%; P < .001; 28 studies). Lower TD prevalence of SGA relative to FGA was also confirmed in the subgroup of studies reporting on ≥ 2 antipsychotic classes/combinations; this was found for both SGAs vs FGAs (risk ratio = 0.80; 95% CI = 0.67-0.95, Z = -2.55, P = .011) and FGA + SGA vs FGAs (risk ratio = 0.80, 95% CI = 0.71-0.90, Z = -3.56, P < .001). Reports on TD severity, provided by 10 studies, were of insufficient quality for meta-analysis.
Rating scale-based TD remains highly prevalent, with higher rates during FGA than during SGA treatment. However, TD severity was insufficiently reported to allow for interpretation of the clinical impact of identified TD cases with SGAs and FGAs. Reasons for high geographical variation warrant future research.
