RESUMO

BACKGROUND: Digital technologies enable the dissemination of multimedia resources to support adults with serious mental illness in their self-management and personal recovery. However, delivery needs to accommodate engagement and accessibility challenges. AIMS: We examined how a digital resource, designed for mental health workers and consumers to use together in session, would be used in routine practice. METHODS: Thirty consumers and their workers participated. The web-based resource, Self-Management And Recovery Technology (SMART), was available to use within and between sessions, for a 6-month period. Workers initiated in-session use where relevant. Feasibility was explored via uptake and usage data; and acceptability and impact via questionnaires. A pre-post design assessed recovery outcomes for consumers and relationship outcomes for consumers and workers. RESULTS: In participating mental health practitioner-consumer dyads, consumers gave strong acceptability ratings, and reported improved working relationships. However, the resource was typically used in one-third or fewer appointments, with consumers expressing a desire for greater in-session use. Improvements in self-rated personal recovery were not observed, possibly contributed to by low usage. CONCLUSIONS: In-session use was found helpful by consumers but may be constrained by other demands in mental health care delivery: collaborative use may require dedicated staff time or more formal implementation.

RESUMO

BACKGROUND: Regular mindfulness practice has been demonstrated to be beneficial for mental health, but mindfulness can be challenging to adopt, with environmental and personal distractors often cited as challenges. Virtual reality (VR) may address these challenges by providing an immersive environment for practicing mindfulness and by supporting the user to orient attention to the present moment within a tailored virtual setting. However, there is currently a limited understanding of the ways in which VR can support or hinder mindfulness practice. Such an understanding is required to design effective VR apps while ensuring that VR-supported mindfulness is acceptable to end users. OBJECTIVE: This study aimed to explore how VR can support mindfulness practice and to understand user experience issues that may affect the acceptability and efficacy of VR mindfulness for users in the general population. METHODS: A sample of 37 participants from the general population trialed a VR mindfulness app in a controlled laboratory setting. The VR app presented users with an omnidirectional video of a peaceful forest environment with a guided mindfulness voiceover that was delivered by a male narrator. Scores on the State Mindfulness Scale, Simulator Sickness Questionnaire, and single-item measures of positive and negative emotion and arousal were measured pre- and post-VR for all participants. Qualitative feedback was collected through interviews with a subset of 19 participants. The interviews sought to understand the user experience of mindfulness practice in VR. RESULTS: State mindfulness (P<.001; Cohen d=1.80) and positive affect (P=.006; r=.45) significantly increased after using the VR mindfulness app. No notable changes in negative emotion, subjective arousal, or symptoms of simulator sickness were observed across the sample. Participants described the user experience as relaxing, calming, and peaceful. Participants suggested that the use of VR helped them to focus on the present moment by using visual and auditory elements of VR as attentional anchors. The sense of presence in the virtual environment (VE) was identified by participants as being helpful to practicing mindfulness. Interruptions to presence acted as distractors. Some uncomfortable experiences were discussed, primarily in relation to video fidelity and the weight of the VR headset, although these were infrequent and minor. CONCLUSIONS: This study suggests that an appropriately designed VR app can support mindfulness practice by enhancing state mindfulness and inducing positive affect. VR may help address the challenges of practicing mindfulness by creating a sense of presence in a tailored VE; by allowing users to attend to visual and auditory anchors of their choice; and by reducing the scope of the content in users' mind-wandering. VR has the unique capability to combine guided mindfulness practice with tailored VEs that lend themselves to support individuals to focus attention on the present moment.

RESUMO

BACKGROUND: The primary objective of this randomised controlled trial (RCT) is to establish the effectiveness of a novel online quality of life (QoL) intervention tailored for people with late stage (≥ 10 episodes) bipolar disorder (BD) compared with psychoeducation. Relative to early stage individuals, this late stage group may not benefit as much from existing psychosocial treatments. The intervention is a guided self-help, mindfulness based intervention (MBI) developed in consultation with consumers, designed specifically for web-based delivery, with email coaching support. METHODS/DESIGN: This international RCT will involve a comparison of the effectiveness and cost-effectiveness of two 5-week adjunctive online self-management interventions: Mindfulness for Bipolar 2.0 and an active control (Psychoeducation for Bipolar). A total of 300 participants will be recruited primarily via social media channels. Main inclusion criteria are: a diagnosis of BD (confirmed via a phone-administered structured diagnostic interview), no current mood episode, history of 10 or more mood episodes, no current psychotic features or active suicidality, under the care of a medical practitioner. Block randomisation will be used for allocation to the interventions, and participants will retain access to the program for 6 months. Evaluations will be conducted at pre- and post- treatment, and at 3- and 6- months follow-up. The primary outcome measure will be the Brief Quality of Life in Bipolar Disorder Scale (Brief QoL.BD), collected immediately post-intervention at 5 weeks (T1). Secondary measures include BD-related symptoms (mania, depression, anxiety, stress), time to first relapse, functioning, sleep quality, social rhythm stability and resource use. Measurements will be collected online and via telephone assessments at baseline (T0), 5 weeks (T1), three months (T2) and six months (T3). Candidate moderators (diagnosis, anxiety or substance comorbidities, demographics and current treatments) will be investigated as will putative therapeutic mechanisms including mindfulness, emotion regulation and self-compassion. A cost-effectiveness analysis will be conducted. Acceptability and any unwanted events (including adverse treatment reactions) will be documented and explored. DISCUSSION: This definitive trial will test the effectiveness and cost-effectiveness of a novel QoL focused, mindfulness based, online guided self-help intervention for late stage BD, and investigate its putative mechanisms of therapeutic action. TRIAL REGISTRATION: ClinicalTrials.gov : NCT03197974 . Registered 23 June 2017.

RESUMO

BACKGROUND: Bipolar disorder (BD) is a complex, relapsing mood disorder characterized by considerable morbidity and mortality. Web-based self-management interventions provide marked opportunities for several chronic mental health conditions. However, Web-based self-management programs targeting BD are underrepresented compared with programs targeting other psychiatric conditions. OBJECTIVE: This paper aims at facilitating future research in the area of self-management of BD and draws insights from the development of one such intervention-the Online, Recovery-Oriented Bipolar Individualised Tool (ORBIT)-that is aimed at improving the quality of life of people with BD. METHODS: We have discussed the opportunities and challenges in developing an engaging, evidence-based, safe intervention within the context of the following three nested domains: (1) intervention development; (2) scientific testing of the intervention; and (3) ethical framework including risk management. RESULTS: We gained the following insights across the three abovementioned overlapping domains: Web-based interventions can be optimized through (1) codesign with consumers with lived experience to ensure relevance and appropriateness to the target audience; (2) novel content development processes that iteratively combine evidence-based information with lived experience perspectives, capitalizing on multimedia (eg, videos) that the digital health space provides; and (3) incorporating Web-based communities to connect end users and promote constructive engagement by access to a Web-based coach. CONCLUSIONS: Self-management is effective in BD, even for those on the more severe end of the spectrum. While there are challenges to be aware of, guided self-management programs, such as those offered by the ORBIT project, which are specifically developed for Web-based delivery provide highly accessible, engaging, and potentially provocative treatments for chronically ill populations who may otherwise have never engaged with treatment. Key questions about engagement, effectiveness, and cost-effectiveness will be answered by the ORBIT project over the next 18 months.

RESUMO

OBJECTIVES: The Internet is increasingly used in mental health service delivery, but there are significant potential barriers to Internet access for persons with severe mental illness (SMI). There is a need to understand this group's access to, and confidence with using, the Internet, and current views on using online resources as part of mental healthcare. METHOD: A survey was conducted of 100 consumers attending a specialist mental health service in Melbourne, Australia. RESULTS: Approximately three-quarters of participants had regular access to the Internet, and two-thirds used the Internet weekly or more. Half of the sample used email at least weekly, and a third were regular users of social networking sites. Internet access was often via mobile devices. Only a minority of participants used the Internet for mental health information, with video streaming and general websites accessed more often than peer forums for mental health content. Most participants were positive about their mental health worker using tablet computers with them in appointments for delivery of mental health materials. CONCLUSION: Most people with SMI are active Internet users and, therefore, able to use interventions online.

RESUMO

Motile cilia perform crucial functions during embryonic development and throughout adult life. Development of organs containing motile cilia involves regulation of cilia formation (ciliogenesis) and formation of a luminal space (lumenogenesis) in which cilia generate fluid flows. Control of ciliogenesis and lumenogenesis is not yet fully understood, and it remains unclear whether these processes are coupled. In the zebrafish embryo, lethal giant larvae 2 (lgl2) is expressed prominently in ciliated organs. Lgl proteins are involved in establishing cell polarity and have been implicated in vesicle trafficking. Here, we identified a role for Lgl2 in development of ciliated epithelia in Kupffer's vesicle, which directs left-right asymmetry of the embryo; the otic vesicles, which give rise to the inner ear; and the pronephric ducts of the kidney. Using Kupffer's vesicle as a model ciliated organ, we found that depletion of Lgl2 disrupted lumen formation and reduced cilia number and length. Immunofluorescence and time-lapse imaging of Kupffer's vesicle morphogenesis in Lgl2-deficient embryos suggested cell adhesion defects and revealed loss of the adherens junction component E-cadherin at lateral membranes. Genetic interaction experiments indicate that Lgl2 interacts with Rab11a to regulate E-cadherin and mediate lumen formation that is uncoupled from cilia formation. These results uncover new roles and interactions for Lgl2 that are crucial for both lumenogenesis and ciliogenesis and indicate that these processes are genetically separable in zebrafish.

RESUMO

BACKGROUND: Psychosocial interventions have an important role in promoting recovery in people with persisting psychotic disorders such as schizophrenia. Readily available, digital technology provides a means of developing therapeutic resources for use together by practitioners and mental health service users. As part of the Self-Management and Recovery Technology (SMART) research program, we have developed an online resource providing materials on illness self-management and personal recovery based on the Connectedness-Hope-Identity-Meaning-Empowerment (CHIME) framework. Content is communicated using videos featuring persons with lived experience of psychosis discussing how they have navigated issues in their own recovery. This was developed to be suitable for use on a tablet computer during sessions with a mental health worker to promote discussion about recovery. METHODS/DESIGN: This is a rater-blinded randomised controlled trial comparing a low intensity recovery intervention of eight one-to-one face-to-face sessions with a mental health worker using the SMART website alongside routine care, versus an eight-session comparison condition, befriending. The recruitment target is 148 participants with a schizophrenia-related disorder or mood disorder with a history of psychosis, recruited from mental health services in Victoria, Australia. Following baseline assessment, participants are randomised to intervention, and complete follow up assessments at 3, 6 and 9 months post-baseline. The primary outcome is personal recovery measured using the Process of Recovery Questionnaire (QPR). Secondary outcomes include positive and negative symptoms assessed with the Positive and Negative Syndrome Scale, subjective experiences of psychosis, emotional symptoms, quality of life and resource use. Mechanisms of change via effects on self-stigma and self-efficacy will be examined. DISCUSSION: This protocol describes a novel intervention which tests new therapeutic methods including in-session tablet computer use and video-based peer modelling. It also informs a possible low intensity intervention model potentially viable for delivery across the mental health workforce. TRIAL REGISTRATION: NCT02474524 , 24 May 2015, retrospectively registered during the recruitment phase.

RESUMO

CONTEXT: This study aimed to develop a near-patient, e-learning tool and explore student views on how utilization of such a tool influenced their learning. METHODS: Third year medical students from Monash University in Melbourne, Australia were invited to trial a novel, near-patient, e-learning tool in two separate pilots within the ward environment. All participating students were invited to contribute to focus groups which were audio-recorded, transcribed verbatim and thematically analyzed. RESULTS: Four focus groups were conducted with a total of 17 participants. The emerging themes revealed influences on the students' learning both prior to and during a clinical encounter, as well as following completion of an e-learning module. The unifying concept which linked all six themes and formed the central feature of the experience was patient-centered learning. This occurred through the acquisition of contextualized knowledge and the facilitation of workplace integration. CONCLUSIONS: Utilization of a near-patient e-learning tool influences medical student learning in a number of complex, inter-related ways. Clinical e-learning tools are poised to become more commonplace and provide many potential benefits to student learning. However, incorporation of technology into clinical encounters requires specific skills which should form an integral part of primary medical training.

RESUMO

Signaling through cell adhesion complexes plays a critical role in coordinating cytoskeletal remodeling necessary for efficient cell migration. During embryonic development, normal morphogenesis depends on a series of concerted cell movements; but the roles of cell adhesion signaling during these movements are poorly understood. The transparent zebrafish embryo provides an excellent system to study cell migration during development. Here, we have identified zebrafish git2a and git2b, two new members of the GIT family of genes that encode ArfGAP proteins associated with cell adhesions. Loss-of-function studies revealed an essential role for Git2a in zebrafish cell movements during gastrulation. Time-lapse microscopy analysis demonstrated that antisense depletion of Git2a greatly reduced or arrested cell migration towards the vegetal pole of the embryo. These defects were rescued by expression of chicken GIT2, indicating a specific and conserved role for Git2 in controlling embryonic cell movements. Git2a knockdown embryos showed defects in cell morphology that were associated with reduced cell contractility. We show that Git2a is required for phosphorylation of myosin light chain (MLC), which regulates myosin II-mediated cell contractility. Consistent with this, embryos treated with Blebbistatin-a small molecule inhibitor for myosin II activity-exhibited cell movement defects similar to git2a knockdown embryos. These observations provide in vivo evidence of a physiologic role for Git2a in regulating cell morphogenesis and directed cell migration via myosin II activation during zebrafish embryonic development.

RESUMO

BACKGROUND: This study was conducted to explore the efficacy and tolerability of quetiapine extended release (XR) to treat psychosis and accompanying acute behavioral disturbance in hospitalized psychiatric patients. METHODS: Patients with psychosis who displayed aggression were administered quetiapine XR (day 1 mean dose: 293.3 mg). Symptoms and side effects were assessed prospectively over an 8-day period. Symptoms were measured by the Overt Aggression Scale and Brief Psychiatric Rating Scale (BPRS), and side effects were measured using the Simpson-Angus Scale and Barnes Akathisia Rating Scale. RESULTS: Fifteen of 16 consenting patients completed the study. Aggression was significantly reduced by day 3. Psychopathology also was significantly reduced, with the greatest improvement in BPRS Thinking Disturbance subscale scores. No significant increase in movement side effects was seen by day 8. Seven participants were administered a concomitant sedating antipsychotic on an as-needed basis, particularly in the first 4 days of treatment; these participants displayed much greater aggression--but not psychopathology--at day 1, and it took longer for their aggression and psychopathology to improve compared with patients treated with quetiapine XR as the sole antipsychotic. CONCLUSIONS: Further research is needed before definitive recommendations can be made. However, current findings provide tentative support for quetiapine XR as a safe and effective medication for treating concurrent psychosis and behavioral disturbance, particularly in less severely aggressive patients.

RESUMO

BACKGROUND: Bipolar II disorder (BD-II) is associated with significant burden, disability, and mortality; however, there continues to be a dearth of evidence-based psychological interventions for this condition. Technology-mediated interventions incorporating self-management have untapped potential to help meet this need as an adjunct to usual clinical care. OBJECTIVE: The objective of this pilot study is to assess the feasibility, acceptability, and clinical utility of a novel intervention for BD-II (Tailored Recovery-oriented Intervention for Bipolar II Experiences; TRIBE), in which mindfulness-based psychological content is delivered via an integrated web and smartphone platform. The focus of the study is evaluation of the dynamic use patterns emerging from ecological momentary assessment and intervention to assist the real-world application of mindfulness skills learned from web-delivered modules. METHODS: An open trial design using pretest and posttest assessments with nested qualitative evaluation was used. Individuals (aged 18-65 years) with a diagnosis of BD-II were recruited worldwide and invited to use a prototype of the TRIBE intervention over a 3-week period. Data were collected via web-based questionnaires and phone interviews at baseline and 3-week follow-up. RESULTS: A total of 25 participants completed baseline and follow-up assessments. Adherence rates (daily app use) were 65.6% across the 3-week study, with up to 88% (22/25) of participants using the app synergistically alongside the web-based program. Despite technical challenges with the prototype intervention (from user, hardware, and software standpoints), acceptability was adequate, and most participants rated the intervention positively in terms of concept (companion app with website: 19/25, 76%), content (19/25, 76%), and credibility and utility in supporting their management of bipolar disorder (17/25, 68%). Evaluation using behavioral archetypes identified important use pathways and a provisional model to inform platform refinement. As hypothesized, depression scores significantly decreased after the intervention (Montgomery-Asberg Depression Rating Scale baseline mean 8.60, SD 6.86, vs follow-up mean 6.16, SD 5.11; t24=2.63; P=.01; Cohen d=0.53, 95% CI 0.52-4.36). CONCLUSIONS: Our findings suggest that TRIBE is feasible and represents an appropriate and acceptable self-management program for patients with BD-II. Preliminary efficacy results are promising and support full development of TRIBE informed by the present behavioral archetype analysis. Modifications suggested by the pilot study include increasing the duration of the intervention and increasing technical support.

RESUMO

Featuring a circular, knotted structure and diverse bioactivities, cyclotides are a fascinating family of peptides that have inspired applications in drug design. Most likely evolved to protect plants against pests and herbivores, cyclotides also exhibit anti-cancer, anti-HIV, and hemolytic activities. In all of these activities, cell membranes appear to play an important role. However, the question of whether the activity of cyclotides depends on the recognition of chiral receptors or is primarily modulated by the lipid-bilayer environment has remained unknown. To determine the importance of lipid membranes on the activity of the prototypic cyclotide, kalata B1, we synthesized its all-D enantiomer and assessed its bioactivities. After the all-D enantiomer had been confirmed by (1)H NMR to be the structural mirror image of the native kalata B1, it was tested for anti-HIV activity, cytotoxicity, and hemolytic properties. The all-D peptide is active in these assays, albeit with less efficiency; this reveals that kalata B1 does not require chiral recognition to be active. The lower activity than the native peptide correlates with a lower affinity for phospholipid bilayers in model membranes. These results exclude a chiral receptor mechanism and support the idea that interaction with phospholipid membranes plays a role in the activity of kalata B1. In addition, studies with mixtures of L and D enantiomers of kalata B1 suggested that biological activity depends on peptide oligomerization at the membrane surface, which determines affinity for membranes by modulating the association-dissociation equilibrium.

RESUMO

OBJECTIVE: The aim of this study was to evaluate the impact of a two-pronged, letter intervention strategy to improve the follow-up after referral (FAR) rate to general practitioners of patients referred for a psychiatric assessment. METHODS: The FAR rate of patients referred to the Inner South East Primary Mental Health Team (PMHT) between June 2007 and June 2008 was examined via telephone call, before and after the implementation of a process sending letters to patients and practice managers advising them to make an appointment to discuss recommendations resulting from the psychiatric assessment. RESULTS: A statistically significant improvement (χ² (1, n = 44) = 5.81, p = 0.016) in FAR rate was observed for patients post-intervention, with 11/25 (44%) pre-intervention patients not returning to their referring general practitioner within 1 month of assessment, compared to 2/19 (10.5%) patients post-intervention. CONCLUSIONS: The implementation of two simple and inexpensive measures resulted in a fourfold improvement in the return rate of patients to their referring general practitioner post-psychiatric assessment.

RESUMO

BACKGROUND: e-Mental health resources are increasingly available for people who experience severe mental illness, including those who are users of community mental health services. However, the potential for service users (SUs) living with severe mental illness to use e-mental health resources together with their community mental health workers (MHWs) has received little attention. OBJECTIVE: This study aims to identify how jointly using an interactive website called Self-Management And Recovery Technology (SMART) in a community mental health context influenced therapeutic processes and interactions between SUs and MHWs from their perspective. METHODS: We conducted a qualitative study using a constructivist grounded theory methodology. Data were collected through individual semistructured interviews with 37 SUs and 15 MHWs who used the SMART website together for 2 to 6 months. Data analysis involved iterative phases of coding, constant comparison, memo writing, theoretical sampling, and consultation with stakeholders to support the study's credibility. RESULTS: A substantive grounded theory, discovering ways to keep life on track, was developed, which portrays a shared discovery process arising from the SU-worker-SMART website interactions. The discovery process included choosing to use the website, revealing SUs' experiences, exploring these experiences, and gaining new perspectives on how SUs did and could keep their lives on track. SUs and MHWs perceived that their three-way interactions were enjoyable, beneficial, and recovery focused when using the website together. They experienced the shared discovery process as relationship building-their interactions when using the website together were more engaging and equal. CONCLUSIONS: Jointly using an e-mental health resource elicited recovery-oriented interactions and processes between SUs and MHWs that strengthened their therapeutic relationship in real-world community mental health services. Further work to develop and integrate this novel use of e-mental health in community mental health practice is warranted.

RESUMO

Objective: Adjunctive psychological interventions improve outcomes in bipolar disorder (BD), but people in latter stages likely have different clinical needs. The objective here was to test the hypothesis that for people with ≥10 episodes of BD, a brief online mindfulness-based intervention (ORBIT 2.0) improves quality of life (QoL) relative to a Psychoeducation control. Method: A rater-masked, pragmatic superiority randomized clinical trial compared ORBIT 2.0 with active control. Both interventions were 5-week coach-supported programs with treatment as usual continued. Inclusion criteria included age 18-65 years, confirmed diagnosis of BD, and history of ≥10 episodes. Measures were collected at baseline, postintervention, and 3- and 6-month follow-ups. The main outcome was QoL, measured on the Brief Quality of Life in Bipolar Disorder (Brief QoL.BD) at 5 weeks, using intention-to-treat analyses. Results: Among N = 302 randomized participants, the primary hypothesis was not supported (Treatment × Time ß = -0.69, 95% CI [-2.69, 1.31], p = .50). The main effect of Time was not significant in either condition, indicating no improvement in either group. Recruitment was feasible, the platform was safe, both interventions were highly acceptable, but usage was suboptimal. Post hoc analyses found both interventions effective for participants not in remission from depression at baseline. Conclusions: In people with late-stage BD, an online mindfulness-based intervention was not superior to psychoeducational control in improving QoL. Online delivery was found to be safe and acceptable. Future interventions may need to be higher intensity, address engagement challenges, and target more symptomatic individuals.

RESUMO

BACKGROUND: Patients are not always fully aware of the details of their assessment and management plan detailed in the letter sent from the specialist to the general practitioner following referral. One approach to solving this problem is for the specialist to copy the GP reply letter to the patient. OBJECTIVE: To determine whether receiving a copy of the GP reply letter improves outcomes in patients referred by their GP for a psychiatric assessment. METHODS: A single blinded randomised control trial comparing outcomes following a one-off consultation for a depressive and/or anxiety disorder in patients who received the GP reply letter sent from a community mental health service, to patients who did not. RESULTS: Data was collected for 21 letter recipients and 18 control participants. A significant group by time interaction found total DASS-21 scores improved to a greater extent for the letter recipient group, no significant difference in adherence was found.

RESUMO

This paper describes the creation of a web-based digital resource designed for tablet computer use during peer work sessions to structure discussion about recovery in early psychosis. The resource consisted of a series of videos featuring young people who have used early psychosis services discussing how they navigated issues in their own recovery. A participatory process was used to create the resource. Researchers held a series of collaborative development workshops with early psychosis service users, peer workers, other mental health practitioners, and academics. These were used to derive a framework of recovery processes relevant to young people experiencing psychosis, which was considered as useful areas of discussion within a peer work relationship. A semi-structured interview guide based on this framework was then used in video-recorded interviews with young people in recovery from psychosis. Footage was edited into 14 videos and organized into six final themes: My Journey, Self-Care, Connections, My Identity, Life, and Mental Health. The combined expertise of young mental health service users, peer support workers, mental health practitioners, and digital mental health researchers throughout the development process enabled the creation of tailored digital resource for peer work in an early psychosis service.

RESUMO

OBJECTIVE: The aim of this study was to investigate the preferences of general practitioners (GPs) in reply letters for patients referred for a one-off psychiatric assessment. METHOD: A sample of GPs referring to a primary mental health team service were mailed a questionnaire inquiring into the usefulness of 21 different letter items. RESULTS: The response rate was 51%. Many of the items in our routine reply letters were rated highly, but others such as developmental history, supplementary information and a comprehensive report were not. Sending a copy of the letter to the patient was rated as useful by only 42.5%. CONCLUSIONS: The Royal Australian and New Zealand College of Psychiatrists' guidelines for reply letters are endorsed. There are, however, some additional items that GPs may find useful.

RESUMO

BACKGROUND: Mental health patients can experience involuntary treatment as disempowering and stigmatising, and contact with recovered peers is cited as important for countering stigma and fostering agency and autonomy integral to recovery. AIMS: To advance understanding of the interaction between involuntary treatment and contact with recovered peers, and explore hypothesised relationships to mechanisms of self-evaluation relevant to recovery. METHOD: Eighty-nine adults diagnosed with serious mental illness completed items to assess involuntary treatment experience and the extent of prior contact with recovered peers, the Internalised Stigma of Mental Illness Scale, the Self-efficacy for Personal Recovery Scale, the Questionnaire about the Process of Recovery and relevant demographic and clinical scales. RESULTS: Contact with recovered peers was found to moderate the effects of involuntary treatment on internalised stigma. Sequential conditional process models (i.e. moderated mediation) then demonstrated that conditional internalised stigma (i.e. moderated by contact with recovered peers) mediated the indirect effect of involuntary treatment on recovery-specific self-efficacy, which in turn influenced recovery. Compared with those with low contact with recovered peers, recovery scores were 3.54 points higher for those with high contact. CONCLUSIONS: Although study methods limit causative conclusions, findings are consistent with proposals that contact with recovered peers may be helpful for this patient group, and suggest this may be particularly relevant for those with involuntary treatment experience. Directions for future research, to further clarify measurement and conceptual tensions relating to the study of (dis)empowering experiences in mental health services, are discussed in detail.

RESUMO

As digital interventions are beginning to be developed to support self-management of psychosis, it is important to understand how illness-related and individual factors may affect internet use and engagement with digital mental health resources among people with psychotic disorders. This study aimed to identify demographic, clinical, and personal variables associated with overall and mental health-related internet use in a sample of 189 adult community mental health service users with nonaffective and affective psychotic disorders. Among participants who regularly used the internet (87.3%), most (67.9%) reported using the internet for mental health information. Higher frequency of overall internet use was predicted by younger age, completion of post-secondary education, and less severe negative symptoms. Internet use for mental health information was predicted by younger age, higher levels of overall internet use, current productive employment, and higher loneliness. This study is the first to quantitatively examine how clinical and personal measures relate to overall and mental health-related internet use in people with psychosis. Although cognitive difficulties and negative symptoms impacted overall internet use, these disorder-related difficulties did not further impact internet use for mental health information. Digital mental health resources should be designed to optimise engagement for this population.
