    Input: OBJECTIVES The study aim ed to test two hypotheses . Firstly , that participants who relapsed during the 12-month follow-up period of our r and omized controlled trial , would show increased negative beliefs about their illness and reduced self-esteem , in comparison to the non-relapsed participants . Secondly , that cognitive behavioural therapy ( CBT ) for early signs of relapse would result in a reduction in negative beliefs about psychosis and an improvement in self-esteem at 12 months . DESIGN AND METHODS A total of 144 participants with schizophrenia or a related disorder were r and omized to receive either treatment as usual ( TAU ; N=72 ) or CBT ( N=72 ) . Participants completed the Personal Beliefs about Illness Question naire ( PBIQ ; Birchwood , Mason , MacMillan , & Healy , 1993 ) and the Rosenberg Self-Esteem Scale ( RSES ; Rosenberg , 1965 ) at entry , 3 months , 6 months , and 12 months . RESULTS At 12 months , relapsers showed greater increase in scores for PBIQ entrapment compared with non-relapsers . In addition , after controlling for baseline covariates ( treatment group and PBIQ self versus illness ) , relapsers also showed greater increase in scores for PBIQ self versus illness at 12 months . Furthermore , in comparison to treatment as usual , participants who received CBT showed greater improvement in PBIQ loss and in Rosenberg self-esteem . CONCLUSIONS The study provides evidence that relapse is associated with the development of negative appraisal s of entrapment and self-blame ( self vs. illness ) . In addition , this is the first study to show that CBT reduces negative appraisal s of loss arising from psychosis and improvements in self-esteem . Implication s for future research and treatment are discussed Background The approximately 1100 medical journals now active in China are publishing a rapidly increasing number of research reports , including many studies identified by their authors as r and omized controlled trials . It has been noticed that these reports mostly present positive results , and their quality and authenticity have consequently been called into question . We investigated the adequacy of r and omization  of clinical trials published in recent years in China to determine how many of them met acceptable st and ards for allocating participants to treatment groups . Methods The China National Knowledge Infrastructure electronic data base was search ed for reports of r and omized controlled trials on 20 common diseases published from January 1994 to June 2005 . From this sample , a subset of trials that appeared to have used r and omization methods was selected . Twenty-one investigators trained in the relevant knowledge , communication skills and quality control issues interviewed the original authors of these trials about the participant r and omization methods and related quality -control features of their trials . Results From an initial sample of 37,313 articles identified in the China National Knowledge Infrastructure data base , we found 3137 apparent r and omized controlled trials . Of these , 1452 were studies of conventional medicine ( published in 411 journals ) and 1685 were studies of traditional Chinese medicine ( published in 352 journals ) . Interviews with the authors of 2235 of these reports revealed that only 207 studies adhered to accepted methodology for r and omization and could on those grounds be deemed authentic r and omized controlled trials ( 6.8 % , 95 % confidence interval 5.9–7.7 ) . There was no statistically significant difference in the rate of authenticity between r and omized controlled trials of traditional interventions and those of conventional interventions . R and omized controlled trials conducted at hospitals affiliated to medical universities were more likely to be authentic than trials conducted at level 3 and level 2 hospitals ( relative risk 1.58 , 95 % confidence interval 1.18–2.13 , and relative risk 14.42 , 95 % confidence interval 9.40–22.10 , respectively ) . The likelihood of authenticity was higher in level 3 hospitals than in level 2 hospitals ( relative risk 9.32 , 95 % confidence interval 5.83–14.89 ) . All r and omized controlled trials of pre-market drug clinical trial were authentic by our criteria . Of the trials conducted at university-affiliated hospitals , 56.3 % were authentic ( 95 % confidence interval 32.0–81.0 ) . Conclusion Most reports of r and omized controlled trials published in some Chinese journals lacked an adequate description of r and omization . Similarly , most so called ' r and omized controlled trials ' were not real r and omized controlled trials owing toa lack of adequate underst and ing on the part of the authors of rigorous clinical trial design . All r and omized controlled trials of pre-market drug clinical trial included in this research were authentic . R and omized controlled trials conducted by authors in high level hospitals , especially in hospitals affiliated to medical universities had a higher rate of authenticity . That so many non-r and omized controlled trials were published as r and omized controlled trials reflected the fact that peer review needs to be improved and a good practice guide for peer review including how to identify the authenticity of the study urgently needs to be developed BACKGROUND Patient-rated unmet need is cross-sectionally associated with quality of life . Its longitudinal relationship has not been established . AIMS To test the hypotheses that : ( a ) higher patient-rated unmet need is associated with lower individual quality of life assessment s by a patient over time ; and ( b ) reduction in patient-rated unmet need precedes improvement in quality of life . METHOD One hundred and one individuals using adult mental health services were asked to complete 6-monthly question naires , comprising  quality of life ( Manchester Short Assessment of Quality of Life , MANSA ) and unmet need ( Camberwell Assessment of Need Short Appraisal Schedule , CANSAS ) assessment s. RESULTS Seventy-three participants provided 240 separate pairs of consecutive assessment s. R and om effects regression models indicated an impact on current quality of life for both average level of unmet need ( B= -0.23 , 95 % CI -0.29 to -0.17 ) and change in unmet need over the past month ( B= -0.04 , 95 % CI -0.02 ) . CONCLUSIONS Changes in patient-rated unmet needs may cause changes in quality of life BACKGROUND Patient-clinician communication is central to mental healthcare but neglected in research . AIMS To test a new computer-mediated intervention structuring patient-clinician dialogue ( DIALOG ) focusing on patients ' quality of life and needs for care . METHOD In a cluster r and omised controlled trial , 134 keyworkers in six countries were allocated to DIALOG  or  treatment as usual ; 507 people with schizophrenia or related disorders were included . Every 2 months for 1 year , clinicians asked patients to rate satisfaction with quality of life and treatment , and request additional or different support . Responses were fed back immediately in screen displays , compared with previous ratings and discussed . Primary outcome was subjective quality of life , and secondary outcomes were unmet needs and treatment satisfaction . RESULTS Of 507 patients , 56 were lost to follow-up and 451 were included in intention-to-treat analyses . Patients receiving the DIALOG intervention had better subjective quality of life , fewer unmet needs and higher treatment satisfaction after 12 months . CONCLUSIONS Structuring patient-clinician dialogue to focus on patients ' views positively influenced quality of life , needs for care and treatment satisfaction Nonadherence to medication is a widespread problem in schizophrenia and is associated with poor clinical outcomes and inappropriate management and utilization of re sources . The aim of the current investigation was to assess the impact of telemonitoring of medication adherence on symptomatology and service use in patients with schizophrenia . A total of 108 schizophrenia patients were r and omized into three equal groups according to the approaches used to assess medication adherence ; self-report , pill counting , and telemonitoring . Telementoring was achieved through an innovative new platform called @HOME . This platform offers clinicians early warnings about impeding nonadherence as well as information about the pattern of medication taking . Patient 's adherence was observed over an 8-week period , during which patient 's clinical status and service use were recorded . In comparison to the other two groups , patients using @HOME showed improvement in the Global Clinical Impression Scale and a significant reduction in emergency visits and medical appointments . The @HOME platform was highly acceptable by patients , caregivers , and professionals , and required minimal training for implementation . The results of the study suggest that the use of telemonitoring in psychiatric setting s was both feasible and acceptable and may be associated with significant clinical and service related benefits BACKGROUND : Interactive Health Communication Applications ( IHCAs ) are computer-based , usually web-based health information packages for patients that combine information with at least one of social support , decision support , or behaviour change support . These are innovations in health care and their effects on health are uncertain . OBJECTIVES : To assess the effects of IHCAs for people with chronic disease . SEARCH STRATEGY : We design ed a four-part search strategy . First , we search ed electronic bibliographic data bases for published work ; second , we search ed the grey literature and third , we search ed for ongoing and recently completed clinical trials in the appropriate data bases . Finally , research ers of included studies were contacted , and reference lists from relevant primary and review articles were followed up . As IHCAs require relatively new technology , the search commenced at 1990 where possible . SELECTION CRITERIA : R and omised controlled trials ( RCTs ) of Interactive Health Communication Applications for adults and children with chronic disease . DATA COLLECTION AND ANALYSIS : One review er screened abstract s. Two review ers screened all c and i date studies to determine eligibility , apply quality criteria , and extract data from included studies . Authors of included RCTs were contacted for missing data . Results of RCTs were pooled using a r and om effects model and st and ardised mean differences ( SMDs ) were calculated to provide net effect sizes . MAIN RESULTS : We screened 24,757 unique citations and retrieved 958 papers for further assessment , yielding 28 RCTs involving 4042 participants . One of these had an inadequate method of concealment of allocation , and sensitivity analyses were performed to determine the effects of including or excluding these data in the meta-analyses . Results in the abstract are from the meta-analyses excluding data from this study .IHCAs were found to have a positive effect on knowledge ( SMD 0.49 ; 95 % confidence interval ( CI ) 0.14 to 0.84 ) and on social support ( SMD 0.47 ; 95 % CI 0.28 to 0.66 ) . IHCAs were found to have no effect on self-efficacy ( SMD 0.15 ; 95 % CI -0.13 to 0.43 ) or behavioural outcomes ( SMD -0.09 ; 95 % CI -0.49 to 0.32 ) . IHCAs had a negative effect on clinical outcomes ( SMD -0.32 ; 95 % CI -0.63 to -0.02 ) . REVIEW ERS ' CONCLUSIONS : The number and range of IHCAs is increasing rapidly ; however there is a shortage of high quality evaluative data . Consumers who wish to increase their knowledge or social support amongst people with a similar problem may find an IHCA helpful . However , consumers whose primary aim is to achieve optimal clinical outcomes should not use an IHCA at present . Further research is needed to determine the reason for this negative effect on clinical outcomes , whether an optimal IHCA can achieve behaviour change and improved health outcomes , and if so , what are the essential features of such an IHCA , and the extent to which they differ according to patient group or condition BACKGROUND Preliminary results have demonstrated the clinical efficacy of computerised cognitive-behavioural therapy ( CBT ) in the treatment of anxiety and depression in primary care . AIMS To determine , in an exp and ed sample , the dependence of the efficacy of this therapy upon clinical and demographic variables . METHOD A sample of 274 patients with anxiety and /or depression were r and omly allocated to receive , with or without medication , computerised CBT or treatment as usual , with follow-up assessment at 6 months . RESULTS The computerised therapy  improved depression , negative attributional style , work and social adjustment , without interaction with drug treatment , duration of preexisting illness or severity of existing illness . For anxiety and positive attributional style , treatment interacted with severity such that computerised therapy did better than usual treatment for more disturbed patients . Computerised therapy also led to greater satisfaction with treatment . CONCLUSIONS Computer-delivered CBT is a widely applicable treatment for anxiety and /or depression in general practice The authors estimated components of variance and intraclass correlation coefficients ( ICCs ) to aid in the design of complex surveys and community intervention studies by analyzing data from the Health Survey for Engl and 1994 . This cross-sectional survey of English adults included data on a range of lifestyle risk factors and health outcomes . For the survey , households were sample d in 720 postal code sectors nested within 177 district health authorities and 14 regional health authorities . Study subjects were adults aged 16 years or more .  ICCs and components of variance were estimated from a nested r and om-effects analysis of variance . Results are presented at the district health authority , postal code sector , and household levels . Between-cluster variation was evident at each level of clustering . In these data , ICCs were inversely related to cluster size , but design effects could be substantial when the cluster size was large . Most ICCs were below 0.01 at the district health authority level , and they were mostly below 0.05 at the postal code sector level . At the household level , many ICCs were in the range of 0.0 - 0.3 . These data may provide useful information for the design of epidemiologic studies in which the units sample d or allocated range in size 
    Output:
    
Adding technology-mediated psychoeducation on top of st and ard care did not clearly improve either general mental state , negative or positive symptoms , global state , level of knowledge or quality of life .
However , the results were not consistent regarding level of knowledge and satisfaction with treatment .
Using ICT to deliver psychoeducational interventions has no clear effects compared with st and ard care , other methods of delivering psychoeducation and support , or both .
