RESUMEN
BACKGROUND AND PURPOSE: Migraine is a common and costly neurological disorder. The aims of this study were to quantify the costs of chronic (CM) and episodic migraine (EM) in Spain, evaluating the impact of psychiatric comorbidities and disability, and to estimate the economic savings associated with reducing the number of migraine-days by 50%. METHODS: This was an observational, cross-sectional analysis of data from migraine patients who participated in the Spanish Migraine Atlas. The participants were invited to complete a structured questionnaire including the following scales: the Headache Needs Assessment, the Hospital Anxiety and Depression Scale, and the Migraine Disability Assessment Scale (MIDAS). RESULTS: A total of 475 patients were included, of whom 187 had CM (39.4%). Total costs per patient/year were: 16 578.2 ± 34 568.1 for CM and 6227.8 ± 6515.7 for EM. A higher degree of disability, according to MIDAS, significantly increased the total cost of migraine, while the presence of psychiatric comorbidity increased costs for EM patients only. A reduction of 1 migraine-day per month decreased average total costs by 744.14 per patient/year for EM and 663.20 per patient/year for CM, while a reduction in the number of migraine-days by 50% would result in economic savings of 2232.44 per patient/year (R2 = 0.927) for EM and 6631.99 per patient/year (R2 = 0.886) for CM. CONCLUSIONS: The costs associated with migraine were driven by migraine frequency and the degree of disability, whereas psychiatric comorbidity only influenced the cost of EM. These results highlight the need to optimize migraine management to reduce the economic migraine burden. Future studies are needed to confirm our results.

BACKGROUND AND PURPOSE: Chitinase 3-like 1 (CHI3L1) and neurofilament light chain (NF-L) are promising biomarkers of disability in multiple sclerosis (MS). However, their role in cognitive dysfunction remains elusive. Here, we aimed to correlate cerebrospinal fluid (CSF) levels of CHI3L1 and NF-L with cognitive status in MS. METHODS: Fifty one recently diagnosed patients were cognitively evaluated and CSF was collected. Levels of CHI3L1 and NF-L were determined by ELISA. Spearman's partial correlation coefficient was performed. RESULTS: After adjusting cognitive scores by age, anxiety and EDSS, association was detected between CHI3L1 levels and Trail Making Test A (rs = 0.348; p = 0.016) and between NF-L levels and Word List Generation (rs = -0.324; p = 0.025). CONCLUSION: High levels of CSF CHI3L1 and NF-L are associated with cognitive impairment in the early phases of MS.

A novel scheme for the focusing of high-energy leptons in future linear colliders was proposed in 2001 [P. Raimondi and A. Seryi, Phys. Rev. Lett. 86, 3779 (2001)]. This scheme has many advantageous properties over previously studied focusing schemes, including being significantly shorter for a given energy and having a significantly better energy bandwidth. Experimental results from the ATF2 accelerator at KEK are presented that validate the operating principle of such a scheme by demonstrating the demagnification of a 1.3 GeV electron beam down to below 65 nm in height using an energy-scaled version of the compact focusing optics designed for the ILC collider.
RESUMEN
OBJECTIVE: Antimicrobial stewardship programs (ASP) have become a key tool in the adaptation of these drugs to the health system. The information available on the application and indicators used in these programs in emergency departments is scarce. The objective of this study is to know the extent of ASP implementation in the emergency departments, as well as the use of antimicrobials in these units. METHODS: Multicenter retrospective study. An invitation was sent to all participants of the REDFASTER-SEFH emergency pharmacist working group. A questionnaire was used consisting of 21 items, answered by a team made up of a pharmacist, emergency room specialist, infectious disease specialist and microbiologist. RESULTS: Eighteen hospitals completed the survey. Fourteen (77.8%) had an ASP manager. The DDD value per 1000 admissions ranged between 36.5 and 400.5 (median: 100.4 [IQR:57.2-157.3]). Both carbapenem and macrolide group presented wide variability in use. Six (33.3%) hospitals had an annual report on the specific resistance profile for urine and blood cultures. The percentage of multi-drug resistant strains in urine cultures was 12.5% and in blood cultures 12.2%. The percentage of adequacy in the bacteremia treatment was 81.0% (IQR:74.6-85.0%), while in urinary tract infections was 78.0% (IQR:71.5-88.0). CONCLUSIONS: Despite the existence of ASP members in emergency services, as well as the training activity and local guidelines is common. knowledge of the use of antimicrobials and resistances is limited. Future activities must be aimed at improving information about the ASP results in these units.

INTRODUCTION: Brolucizumab is a novel anti-vascular endothelial growth factor (anti-VEGF) drug administered in a fixed regimen of 8 or 12 weeks which, in the HAWK and HARRIER studies, was shown not to be inferior to aflibercept with respect to the best corrected visual acuity, with a less burdensome treatment regimen. The aim of the analysis was to compare the direct healthcare costs of both anti-VEGF as a treatment in patients with neovascular age-related macular degeneration. MATERIAL AND METHODS: A cost minimization analysis was performed under a 25-year time horizon and considering the drug costs, administration, follow-up tests, and management of adverse events. Resource use was obtained from the related literature and validated by clinical experts. Various scenario analysis were carried out to check the robustness of the results. RESULTS: Brolucizumab resulted in a lower cost per patient compared with aflibercept, considering the number of injections derived from the HAWK and HARRIER studies. This result was maintained in the different scenarios analysed, except for the number of injections of the flexible aflibercept regimen of the ARIES study, since the lower discontinuation of treatment with brolucizumab implies maintaining the treatment of more patients. Considering the same discontinuation, brolucizumab maintained the results observed in the base case of the analysis. CONCLUSIONS: This study shows how the fixed administration regimen of brolucizumab can help reduce both healthcare and patients' burden.

AIM: To compare the effectiveness and costs of the implementation of the Intravitreal Therapy Unit Model, endorsed by the SERV, SECA, SEO and SEDISA, compared to the usual procedure. METHOD: Analytical decision model that compares an UTI-type healthcare organization with 4 usual practice scenarios in Spain, in terms of quality-of-life results due to loss of visual acuity and the use of resources. The probability, cost, and quality-adjusted life years (QALYs) were estimated for each scenario proposed. A univariate sensitivity analysis was performed for each of the parameters used in the model. RESULT: The model showed that from any of the initial scenarios of the usual practice, transitioning to the UTI-type implementation improves the quality of life of patients and requires lower cost. UTI-type is dominant respect usual practice. The sensitivity analysis showed that the results would not change sign with the variation of any starting variable. CONCLUSIONS: Shorten suspicion-needle times is key to maintaining functional vision in patients requiring intravitreal treatment. The UTI-type model seeks the efficiency of ophthalmology services and can produce savings that vary between Ð175 and Ð85 per patient attended per year.

The aim of the present work was to study how the information on product labels influences consumer expectations and their acceptance and purchase intention of dark chocolate. Six samples of dark chocolate, varying in brand (premium and store brand) and in type of product (regular dark chocolate, single cocoa origin dark chocolate and high percentage of cocoa dark chocolate), were evaluated by 109 consumers who scored their liking and purchase intention under three conditions: blind (only tasting the products), expected (observing product label information) and informed (tasting the products together with provision of the label information). In the expected condition, consumer liking was mainly affected by the brand. In the blind condition, differences in liking were due to the type of product; the samples with a high percentage of cocoa were those less preferred by consumers. Under the informed condition, liking of dark chocolates varied depending on both brand and type of product. Premium brand chocolates generated high consumer expectations of chocolate acceptability, which were fulfilled by the sensory characteristics of the products. Store brand chocolates created lower expectations, but when they were tasted they were as acceptable as premium chocolates. Claims of a high percentage of cocoa and single cocoa origin on labels did not generate higher expectations than regular dark chocolates.

INTRODUCTION: Measuring health outcomes and costs per patient is an essential element of value-based healthcare (VBHC). The aim of the study was to generate expert consensus on the activities required to implement it. METHODS: A two-round modified Delphi study with healthcare professionals, quality and clinical management methodologists and managers with academic and/or practical experience in outcome measurement projects. A median equal to or greater than 4 and a relative interquartile range (RIQR) equal to or greater than 25% were established as consensus criteria. RESULTS: Consensus was obtained on 91% of the items (N=74/81). In terms of feasibility, the items that received the highest score and consensus were the existence of data protection guarantees (median=5; mean=4.8; RIQR=0%), the vision and motivation of healthcare professionals (median=5; mean=4.7; RIQR=20%), the existence and availability of ICT tools (or systems) for data recording (median=5; mean=4.5; RIQR=20%), and having sufficient funding to undertake the project (median=5; mean=4.2; RIQR=20%). The most highly rated factors adding complexity were the number of units or departments involved in the care process for the clinical condition (median=5; mean=4.4; RIQR=20%), having an accepted set of monitoring indicators for the condition (median=5; mean=4.4; RIQR=20%), and the involvement of several levels of care in the project (median=5; mean=4.3; RIQR=20%). CONCLUSIONS: We describe practical aspects for the application of systematic outcomes measurement in routine clinical practice. These results can serve as a tool for prioritising, sizing, resource planning, and estimating implementation costs.

BACKGROUND AND OBJECTIVES: Epidemiologic and disease burden data are essential for disease control and optimal health care resource planning. The aims of this study were to estimate the epidemiologic burden of psoriasis and evaluate associated comorbidities, health care utilization, and sick leave. MATERIAL AND METHODS: We collected data from the 2016 Catalan Health Survey (ESCA), the Catalan Registry of Morbidity and Utilization of Health Care Services (MUSSCAT) (2016), and the database of the Catalan Medical Evaluations Institute (ICAM) (2012-2016). RESULTS: The prevalence of psoriasis in Catalonia according to 2016 ESCA data is approximately 1.8%. The MUSSCAT registry data indicate that the incidence has remained stable in recent years. The most common comorbidities associated with psoriasis are hypertension (35%) and diabetes (15%). Forty percent of patients with psoriasis have a moderate to high risk for death or high health resource utilization. Annual use of resources by psoriasis patients is high: they make a mean of 8.7 primary care visits, 2.8 outpatient visits, 0.5 emergency and day hospital visits, 0.2 mental health visits, and use 6.1 medications. Sick leave due to psoriasis or psoriatic arthritis accounted for 0.04% of all cases. CONCLUSIONS: The prevalence of psoriasis in Catalonia is high at 1.8%. The disease burden is also high, both in terms of comorbidities and health care utilization.

BACKGROUND: It has become widely accepted that cognitive deficits in schizophrenia are related to functional outcome. However, it remains to be seen whether these associations are relevant for predicting which cases will have a global functional recovery. In this study, we attempt to determine whether global functional recovery (integrating social and occupational outcomes) after first-episode schizophrenia (FES) can be predicted by cognitive variables. METHOD: A total of 131 FES patients with functional deficits (n=97) and functional recovery (n=34) as determined at 1-year follow-up were examined. Neuropsychological, sociodemographic, pre-morbid and clinical data at baseline were analysed using independent groups comparisons and a logistic regression method. RESULTS: Sustained attention and negative symptoms emerged as significant predictors of good global functional outcome. Although the model revealed a high accuracy (91%) in the classification of patients with functional deficits, it was unacceptably low (26%) in the classification of patients with global functional recovery. CONCLUSIONS: The limitations found in the prediction of a favourable global functional outcome may well be an indication for a need to address the role of other factors not commonly included in longitudinal studies of long-term outcomes in schizophrenia.

INTRODUCTION: Psychological therapies can modify thoughts, feelings, and behaviors of people with mental disorders, but the underlying brain mechanisms remain to be clarified. Advances in neuroimaging techniques can help us to understand of how different psychotherapies change the human brain. This review has aimed to systematically investigate the brain effects of psychological therapies for adults with anxiety disorders. METHOD: Several electronic databases (Medline, PsycINFO, EMBASE and EBSCO) up to April 2010 were searched. Abstracts which appeared to fulfill the initial selection criteria (a structured psychological treatment in adults with anxiety disorders with at least one neuroimaging study performed before and after the treatment) were selected and their original articles were then retrieved. References from the selected English and Spanish language publications were also hand searched. RESULTS: Eighteen studies met the criteria for inclusion in the review. The majority of these papers reported cognitive-behavioral therapy (CBT) in specific phobia, social phobia, obsessive-compulsive disorder (OCD), posttraumatic stress disorder or panic disorder. Psychological interventions changed neural circuits involved in the pathophysiology of anxiety disorders, especially activity in frontal-striatal circuits in OCD and prefrontal areas in arachnophobia. However, the results are largely inconsistent among themselves and with the neurobiological models of anxiety, in particular as regards the changes at the limbic level. CONCLUSIONS: Despite the variety of methodological concerns, initial neuroimaging studies have showed that psychological interventions can change brain function related to anxiety disorders in the patients who respond to treatment. Neuromodulation mechanisms related to specific anxiety disorders remained to be elucidated. Future studies should delineate the process of "normalization" that occurs in the brain during a psychological treatment, helping to enrich the current neurobiological models of the origins, maintenance and treatment of anxiety disorders.

BACKGROUND: Psychological and pharmacological treatments have been shown to reduce rates of transition to psychosis in Ultra High Risk (UHR) young people. However, social functioning deficits have been unresponsive to current treatments. AIMS: The study aims were to: i) describe the theoretical basis and therapeutic targets of a novel intervention targeting social functioning in UHR young people; and ii) examine its acceptability, safety and preliminary effect on social functioning. METHODS: An international, multidisciplinary team developed a new intervention (MOMENTUM) to improve social functioning in UHR young people. MOMENTUM blends two novel approaches to social recovery: strengths and mindfulness-based intervention embedded within a social media environment, and application of the self-determination theory of motivation. The acceptability and safety of MOMENTUM were tested through a 2-month pilot study with 14 UHR participants. RESULTS: System usage was high, with over 70% of users being actively engaged over the trial. All participants reported a positive experience using MOMENTUM, considered it safe and would recommend it to others. 93% reported it to be helpful. There were large, reliable improvements in social functioning (dâ¯=â¯1.83, pâ¯<â¯0.001) and subjective wellbeing (dâ¯=â¯0.75, pâ¯=â¯0.03) at follow-up. There were significant increases in the mechanisms targeted by the intervention including strengths usage (dâ¯=â¯0.70, pâ¯=â¯0.03), mindfulness skills (dâ¯=â¯0.66, pâ¯=â¯0.04) and components of social support. Social functioning improvement was significantly correlated with indicators of system usage. CONCLUSION: MOMENTUM is engaging and safe. MOMENTUM appeared to engage the hypothesized mechanisms and showed promise as a new avenue to improve social functioning in UHR young people.

BACKGROUND AND OBJECTIVE: Adherence to treatment in patients with psoriasis is often poor. An investigation of patient preferences and satisfaction with treatment may be important, based on the expected correlation with therapy compliance. This paper aims to examine and describe the current literature on patient preferences, satisfaction and adherence to treatment for psoriasis in the European Union (EU). METHODS: Electronic searches were conducted using PubMed, ISI Web of Knowledge, Scopus, Spanish databases and Google Scholar. European studies published in English or Spanish between January 1, 2009 and December 31, 2014 regarding patient-reported outcomes in psoriatic patients were included. Studies conducted in non-EU countries, letters to the editor, editorials, experts' opinions, case studies, congress proceedings, publications that did not differentiate between patients with psoriasis and psoriatic arthritis or studies related to specific treatment were excluded. RESULTS: A total of 1,769 titles were identified, of which 1,636 were excluded as they were duplicates or did not provide any relevant information. After a full-text reading and application of the inclusion/exclusion criteria, 46 publications were included. This paper will describe publications on adherence (n=4), preferences (n=5) and satisfaction with treatment (n=7). Results related to health-related quality of life articles (n=30) have been published elsewhere. Adherence rates are generally low in psoriasis patients regardless of the type of treatment, severity of disease or methods used to measure adherence. Biologic therapy is associated with greater clinical improvement. There is a direct association between physician recommendations, patient preferences and several domains of treatment satisfaction. CONCLUSION: The results of this review support the conclusion that adherence rates in patients with psoriasis are suboptimal and highlight the need to improve patient compliance and satisfaction with treatment. Patients' preferences should be taken into account in the treatment decision-making process in order to improve patients' clinical outcomes by ensuring satisfaction and adherence.
RESUMEN
Treatment guidelines for first episode psychosis (FEP) recommend at least 1 year of antipsychotic treatment following remission; however, in light of some recent research and the preference of some individuals to discontinue their medication sooner, this recommendation can be questioned. The aim of this article is to appraise the current discontinuation studies given our views on how this field should progress. We conducted a review of randomized controlled trials investigating dose-reduction/medication discontinuation compared with treatment maintenance in clinically remitted FEP patients. Seven trials were identified, and these reported a higher rate of relapse in the dose reduction or discontinuation groups. Relapse rates were higher when a lower threshold for relapse was utilized. However, only three studies specified that concurrent psychosocial interventions were also provided, despite an evidence base for these interventions in reducing symptom severity and relapse. Length of follow-up may also be important, as the study with the longest follow-up (7 years), albeit with some methodological shortcomings, found greater functional recovery in the dose-reduction group and that relapse rates between the two groups (dose-reduction vs. maintenance) were equal after 3 years. Finally, in addition to discontinuation or dose reduction, a diagnosis of schizophrenia, a longer duration of illness, and poor premorbid functioning were associated with a greater risk of relapse. Further trials are needed in this area to establish the long-term risk-benefit ratio of antipsychotic medication in FEP. Meanwhile, young people with FEP who do not fulfil criteria for a diagnosis of a schizophrenia disorder, achieve clinical remission for at least 3 months, attain early functional recovery, and have good social support may be possible candidates for discontinuation of antipsychotic medication bolstered by effective psychosocial interventions provided in the context of a specialized FEP service.

Nutritional composition and fatty acids (FA) profile were determined in cocoa and chocolates of different geographical origin and subject to different processing conditions. Cocoa butter was the major nutrient in cocoa beans and carbohydrates were the most important in chocolates. Cocoa composition and FA profile varied depending on geographical origin whilst in chocolates only carbohydrates and fat content varied significantly due to the effect of origin and no significant effect was observed for processing conditions. Both for cocoa and chocolates differences in FA profile were mainly explained as an effect of the geographical origin, and were not due to processing conditions in chocolate. For cocoa, differences in FA profile were found in C12:0, C14:0, C16:0, C16:1, C17:0, C17:1 and C18:0 whilst for chocolates only differences were found in C16:0, C18:0, C18:1 and C18:2. For all samples, C16:0, C18:0, C18:1 and C18:2 were quantitatively the most important FA. Ecuadorian chocolate showed a healthier FA profile having higher amounts of unsaturated FA and lower amounts of saturated FA than Ghanaian chocolate.

Carers' expressed emotion (EE) and patients' cannabis misuse are two of the most robust predictors of psychotic relapse. We aimed to examine the temporal relationship between EE and cannabis misuse. Sixty-three key carers of young people with first-episode psychosis (FEP) were assessed at baseline and 7-month follow-up. EE was measured in carers using the Family Questionnaire (FQ) and cannabis misuse in patients using the Alcohol, Smoking and Substance Involvement Screening Test (ASSIST). Correlational and hierarchical logistic regression analyses were conducted to examine the temporal relationship between EE components (i.e. criticism and emotional over involvement) and cannabis misuse. Carers' criticism at baseline significantly predicted cannabis misuse according to the ASSIST at 7-month follow-up. The association remained significant after controlling for baseline symptom severity and social functioning (B=0.15, P=.02). Conversely, baseline cannabis misuse was not associated with carers' criticism at 7-month follow-up. Patients in families with high criticism showed a tendency to increase cannabis misuse over time whereas the opposite trend was observed in those with carers with low criticism. A family environment characterized by high criticism may become a key risk factor for worsening cannabis misuse over time in young people with FEP. Further studies should investigate the potential mechanisms (e.g., patient's anxiety or perceived stress) through which criticism increases cannabis misuse in FEP.

As part of the first quantitative study of men who have sex with men (MSM) and HIV/ AIDS in Spain, anonymous, self-administered questionnaires were distributed via gay/lesbian organization mailings, bathhouses, and sex shops in Barcelona. We analyzed 547 gay/bisexual men along self-reported HIV testing history-i.e. untested, previously tested HIV-, and previously tested HIV +. Eleven variables discriminated significantly between the three groups in multivariable analysis. HIV- men were over-represented in the mailing subsample. While untested men exhibited potentially protective behaviors (e.g. least likely to have had stable and casual sex partners with HIV/AIDS and to practice anal intercourse), they were also least likely to be out with their homosexuality and most likely to never use condoms when they practiced anal intercourse. HIV + men were most likely to report insertive and receptive anal intercourse with a condom and least likely to practice insertive anal intercourse without a condom in the past month, yet they were also most likely to report the highest interpersonal barriers to safer sex, recent cocaine use with sex, meeting sex partners in public restrooms, and recent episodes of STD. A potentially volatile combination of higher sexual activity (e.g. more sex partners and casual sex activity) coupled with the presence of safer sex barriers (e.g. poor scores on indices measuring safer sex disposition, elevated drug use accompanying sex) was evidenced among HIV + men. There were no statistically significant differences between the three groups for anal intercourse without a condom, but with 37.5% of this collective reporting one such episode in the past month, all groups can be considered equally risky. Against the backdrop of a 20.5% self-reported HIV prevalence, there is considerable need for enhanced prevention efforts among gay/bisexual men in general and targeted strategies among HIV + men in particular.

BACKGROUND: AIDS is one of the most important problems of public health in our setting. The surveillance of HIV infection in sentinel population is an important alternative to the use of the AIDS cases registries, to obtain a dynamic and updated information about HIV/AIDS epidemic. The objective of this study was to determine the prevalence of HIV infection among the patients from 5 sentinel hospitals in Catalonia, Spain. PATIENTS AND METHODS: Unlinked anonymous screening of serum from patients aged 15-49 from 5 sentinel hospitals in Catalonia, Spain. Samples were broken by age, sex, in-patients or out-patients and clinical specialities related to HIV/AIDS or not related. Samples were analyzed in pools of five and were tested by the OMS strategy II, for the epidemiological surveillance purposes. RESULTS: HIV testing was developed in 9,524 patients, with a prevalence of 1.6% (153 samples). The overall prevalence in men was twice that of women (2.3% vs. 1.1%). Ages between 25 to 34 had the higher prevalence (3.1%). Clinical specialities related with HIV/AIDS had a prevalence twice that of non related (2.3% vs. 1.2%). CONCLUSIONS: The HIV prevalence found in this population is the highest compared to similar studies performed in other western european countries. Our data confirm the pattern of HIV infection for age and sex observed in other studies in Catalonia, Spain. This is the first study of sentinel surveillance in sentinel hospitals in Spain and give us the base line which will serve as a reference to assess the evolution of HIV infection in further studies in sentinel hospital populations in Catalonia.

OBJECTIVE: To describe the process performed in Catalonia (Spain) to design an information system for monitoring new cases of HIV infection. METHODS: A survey was used to evaluate perception of the need for notification of HIV infection by health care professionals (n = 106), as well as their opinions of the various possibilities for the implementation of the notification system. As a result of this evaluation, a specific technical report defining the objectives and technical characteristics of the new notification system was produced. The feasibility of the system in health centres was evaluated through discussions with health care professionals, health authorities and Non-Governmental Organizations, and a second survey was designed to evaluate the use of a personal identification code (PIC) from the individual health card (IHC). This process took plabe between 1998 and 2000. RESULTS: A total of 84.5% of the health care professionals believed that HIV notification should be mandatory and confidential; 90.4%, were of the opinion that notification would enable identification of the epidemiological characteristics of infected individualos, and 75% believed that these individuals would have to be identified by name. Finally, 66% of the health care professionals believed that the use of the PIC from the IHC would be feasible as the personal identifier in HIV notification. A final proposal was draw up and 1 January, 2001 was set as the date to initiate the pilot phase of the new HIV notification system. CONCLUSIONS: Most of the health care professionals surveyed expressed the need for notification of HIV infection, and for such notification to receive institutional endorsement. They also believed that, as with other diseases of individualized mandatory reporting, notification should be carried out with a single personal identifier. The information obtained from notification of HIV infection is essential for the optimal planning of preventive programs and the provision of health services. The main difficulties observed were that HIV infection has not been included among the diseases of mandatory reporting, as well as the low implantation of the PIC in the hospitals' clinical registries. All the sectors involved have an important role to play in creating the conditions necessary for the notification system of new cases of HIV infection to be feasible and useful.

BACKGROUND: Internet and mobile-based interventions provide a unique opportunity to deliver cost-effective, accessible, time-unlimited support to people with psychosis. The aims of this study were to systematically compile and analyze the evidence on the acceptability, feasibility, safety and benefits of online and mobile-based interventions for psychosis. METHODS: Systematic review of peer-reviewed studies examining the usability, acceptability, feasibility, safety or efficacy of user-led, Internet or mobile-based interventions, with at least 80% of participants diagnosed with schizophrenia-spectrum disorders. RESULTS: Of 38 potentially relevant articles, 12 were eligible for inclusion. Interventions included web-based psycho-education; web-based psycho-education plus moderated forums for patients and supporters; integrated web-based therapy, social networking and peer and expert moderation; web-based CBT; personalized advice based on clinical monitoring; and text messaging interventions. Results showed that 74-86% of patients used the web-based interventions efficiently, 75-92% perceived them as positive and useful, and 70-86% completed or were engaged with the interventions over the follow-up. Preliminary evidence indicated that online and mobile-based interventions show promise in improving positive psychotic symptoms, hospital admissions, socialization, social connectedness, depression and medication adherence. CONCLUSIONS: Internet and mobile-based interventions for psychosis seem to be acceptable and feasible and have the potential to improve clinical and social outcomes. The heterogeneity, poor quality and early state of current research precludes any definite conclusions. Future research should investigate the efficacy of online and mobile interventions through controlled, well-powered studies, which investigate intervention and patient factors associated with take-up and intervention effects.
