Beyond the usual suspects: positive attitudes towards positive symptoms is associated with medication noncompliance in psychosis

Stigma and its associations with medication adherence in major depressive disorder

This study sought to evaluate internalized stigma (IS) and perceived stigma (PS), in persons (n = 522) living with major depressive disorder (MDD), with a view to analyzing the association of IS and PS with medication adherence in a cohort of participants with MDD in China. Perceived stigma is the awareness of societal negative views and attitudes towards depression, and IS is applying others' attitudes to oneself, both measured by the Depression Stigma Scale (DSS). Medication adherence was assessed using the Medication Adherence Rating Scale (MARS). We observed that 76.0 % of participants reported IS and 84.5 % reported PS. Factors associated with increased IS included older age, marital status, disease history, and a higher baseline Patient Health Questionnaire-9 (PHQ-9). Higher education level, family income, and scores on the Connor-Davidson Resilience Scale (CD-RISC) were associated with lower levels of IS. Higher education levels, Childhood Trauma Questionnaire (CTQ) scores, and living with others were also associated with higher PS, while engagement in exercise and higher number of prior episodes were associated with lower PS. IS had a negative association with medication adherence, whereas PS did not significantly associate with adherence. In conclusion, a testable hypothesis is derived from our data that strategies targeting IS amongst persons with MDD may improve overall rates of adherence to antidepressant treatment, a necessary prelude to improving recovery.

Hasty decision making and belief inflexibility in the more delusion prone? A modified disambiguating-scenarios paradigm assessing cognitive biases implicated in delusions

INTRODUCTION

Contemporary models of psychosis imply that cognitive biases such as the jumping to conclusions (JTC), the bias against disconfirmatory evidence (BADE), and the liberal acceptance (LA) bias play a role in the pathogenesis of delusions. Most of the studies investigating the role of cognitive biases, however, have been conducted with socially neutral or abstract stimuli and have assessed patients with established psychoses. For the present study, we aimed to concurrently investigate multiple biases (i.e., the JTC, BADE, and LA biases) in a community sample with a new paradigm using more socially engaging stimuli.

METHODS

A large sample of participants (N = 874) recruited via Amazon Mechanical Turk was subdivided into two groups based on the frequency of their psychotic-like experiences (PLEs) according to the positive subscale score of the Community Assessment of Psychic Experiences (CAPE) and matched based on major demographics variables, resulting in two equally sized groups called High-PLE (at least 2 SD above the mean) and Low-PLE (maximum 0.5 above the mean; n = 46 for each group). Using a modified version of the written-scenarios BADE task, which emphasized social interactions between agents embedded in the scenario, participants rated the plausibility of response options in the face of new information.

RESULTS

In line with previous findings, the High-PLE group demonstrated the JTC, BADE, and LA biases. That is, the members of this group made more decisions after the initial piece of information, were less likely to revise their beliefs in light of new information, and provided higher plausibility ratings for implausible response options compared to the Low-PLE group.

CONCLUSIONS

Results corroborate prior findings suggesting that the JTC, BADE, and LA biases may be contributing factors in delusional ideation and that metacognitive biases extend to social situations.

Trends, characteristics, race, and ethnicity associated with nonadherence to antidepressants among breast cancer survivors with depression

BACKGROUND: Breast cancer is the most diagnosed cancer in the United States, and half of breast cancer survivors experience major depressive disorders (hereafter depression). Healthcare Effectiveness Data and Information Set (HEDIS) quality measures evaluating depression treatment practices recommend uninterrupted antidepressant treatment for 3 months in the acute phase and 3 months in the continuation phase for the general population. However, little is known about the extent of and trends in antidepressant nonadherence among breast cancer survivors with depression, which may impact adherence to breast cancer treatment, potentially leading to breast cancer recurrence and other adverse outcomes. OBJECTIVE: To examine the trends and characteristics associated with antidepressant nonadherence among breast cancer survivors with depression in the United States. METHODS: We conducted cross-sectional analyses of Surveillance, Epidemiology, and End Results linked with Medicare data (2010-2019) for women with breast cancer and depression who newly initiated antidepressant use. Using HEDIS measures of nonadherence (ie, antidepressant prescription coverage ≤84 days of the 114-day acute phase or ≤180 days of the 231-day continuation phase), we calculated the annual crude prevalence of antidepressant nonadherence and examined trends using unadjusted logistic regression. Multivariable logistic regression identified characteristics associated with antidepressant nonadherence. RESULTS: Among 9,452 eligible breast cancer survivors with depression (aged ≥65 years = 84% and White race = 82%), the crude prevalence of antidepressant nonadherence decreased from 2010 to 2019 for both the acute (49% to 40%; P_trend<0.001) and continuation (67% to 57%; P_trend<0.001) phases. Factors significantly associated with higher odds of antidepressant nonadherence in both the acute and continuation phases included Black race (odds ratios [ORs] [95% CI] for the acute/continuation phases: 2.0 [1.7-2.4]/2.0 [1.7-2.3]) and Hispanic ethnicity (1.5 [1.1-1.9]/2.2 [1.6-2.9]) compared with White race; receiving the first antidepressant from an oncologist vs a psychiatrist (1.4 [1.1-1.8]/1.6 [1.2-2.0]); and using antidepressants not recommended for older adults by the Beers criteria (2.2 [1.6-2.9]/2.0 [1.4-2.7]). Factors associated with lower odds of antidepressant nonadherence in both phases included receiving lymph node dissection (0.7 [0.5-0.9]/0.7 [0.5-0.9]), receiving endocrine therapy (0.9 [0.8-0.9]/0.8 [0.7-0.9]), having a higher National Cancer Institute comorbid index (0.8 [0.7-0.8]/0.9 [0.8-0.9]), having a follow-up visit with a psychiatrist (0.9 [0.8-0.9]/0.9 [0.8-0.9]), and switching to different antidepressants (0.7 [0.6-0.8]/0.7 [0.7-0.8]). CONCLUSIONS: Despite antidepressant nonadherence prevalence decreasing from 2010 to 2019, over half of breast cancer survivors with depression and Medicare were nonadherent in the continuation phase. Patients with identified nonadherence risk factors may benefit from close monitoring and targeted interventions.

Bei Risiken und Nebenwirkungen fragen Sie Ihre… Patientinnen und Patienten

Zusammenfassung: Theoretischer Hintergrund: Das Verständnis der Antipsychotika-Adhärenz ist lückenhaft, obwohl sie ein Grundpfeiler der Schizophrenie-Behandlung darstellt. Die spezifische Erfassung der Wahrnehmung von Risiken bei Einnahme sowie Absetzen von Antipsychotika könnte zur Erklärung der Adhärenz beitragen. Fragestellung: Explorative Studie zur Entwicklung und ersten Evaluierung des Fragebogens zur Risikowahrnehmung von Antipsychotika (FRA). Methode: Basierend auf theoretischen Überlegungen wurde ein Itempool für die Risikowahrnehmung des Absetzens und Einnehmens von Antipsychotika generiert. Eingeschlossen wurden ambulante und stationäre F2-Patient_innen. Stichprobe 1 ( N = 120) diente zur Itemselektion und explorativen Faktorenanalyse (faktorielle Validität). Anhand Online-Stichprobe 2 ( N = 39) wurde die diskriminante und konvergente Validität analysiert. Ergebnisse: Die explorative Faktorenanalyse ergab die theoretisch erwartete zweifaktorielle Struktur. Die Korrelationen des FRA zu Adhärenzmaßen und spezifischen Medikamentenfragebögen unterstützten die konvergente und diskriminante Validität. Schlussfolgerungen: Der FRA als Erhebungsinstrument der Wahrnehmung von Antipsychotika-Risiken könnte das Verständnis von Antipsychotika-Adhärenz und von Behandlungsansätzen verbessern. Prospektive konfirmatorische Studien müssen durchgeführt werden.

Attitudes toward and patterns of medication use among people with serious mental illness: There's more than meets the eye

Background and aim

There are growing concerns about the long-term effects of psychiatric medication after a major psychiatric crisis. Recent evidence shows a diverse impact of long-term use on various outcome domains, which may help explain why non-adherence is so common. In the current study we explored the subjective perceptions of factors that impact both attitudes toward and patterns of use of medication among individuals with serious mental illness (SMI).

Method

Sixteen individuals with an SMI and a recognized psychiatric disability who had used psychiatric medication for at least 1 year were recruited for the study via mental health clinics and social media. Participants were interviewed using a semi-structured interview based on the narrative approach, focusing on attitudes toward and patterns of use of psychiatric medication. All interviews were transcribed and analyzed using thematic analysis.

Results

Three discrete sequential phases emerged, each characterized by different themes referring to attitudes toward medication and patterns of use: (1) "loss of self" and a high level of medication use; (2) accumulating experiences of using/reducing/stopping medication; and (3) forming more stable attitudes toward medication and developing one's own pattern of use. The transition between phases was dynamic in nature and represents a non-linear process. Complex interactions were generated at different phases between the related themes, which shaped attitudes toward medication and patterns of use.

Conclusions and implications

The current study reveals the complex ongoing process of forming attitudes toward medication and patterns of use. Recognizing and identifying them via a joint reflective dialog with mental health professionals can enhance alliance, shared decision-making, and person-centered recovery-oriented care.

In the eyes of the beholders: Subjective experiences of positive symptoms among patients with symptoms of psychosis seeking psychotherapy

BACKGROUND

Reduction of positive symptoms is often the focus of psychiatric treatment for patients with psychosis; however, it is becoming increasingly clear that some patients experience ambivalence towards positive symptoms or may even experience them as pleasant. The present study extends upon work from online studies of patients without verified diagnoses. The first aim was to examine the frequency with which patients report negative, neutral or even positive appraisals of positive symptoms. A second aim was to identify whether these appraisals were associated with medication adherence.

METHODS

One-hundred twelve treatment-seeking patients with current symptoms of psychosis completed the Subjective Perception of Positive Symptoms-Revised (SUPPOSY-R), a scale assessing appraisals of positive symptoms (e.g., gain from illness, impact on daily life), as well as questions regarding medication adherence.

RESULTS

Although most patients reported experiencing positive symptoms as predominantly unpleasant, appraisals differed between symptom clusters and up to 54.4 % reported that they would miss at least some aspects of positive symptoms should they disappear. Patients particularly welcomed the disappearance of auditory hallucinations (71.2 %). Symptom appraisal was not significantly associated with medication compliance (p > .17); however, more patients with low medication adherence reported they would feel at least some regret if their symptoms were to completely disappear (48.9 %, n = 23) versus patients with high adherence (41.7 %, n = 20).

DISCUSSION

Ambivalent or positive appraisals of positive symptoms are lower among treatment-seeking patients compared to patients recruited for online studies, who may not be actively seeking treatment. Auditory hallucinations may cause most distress among treatment-seeking patients. A collaborative approach including assessment of possible positive appraisals of symptoms is important when identifying treatment goals.

Whodunit - A novel video-based task for the measurement of jumping to conclusions in the schizophrenia spectrum

Jumping to conclusions (JTC) is implicated in the formation and maintenance of the positive symptoms of psychosis and over the years has become a prominent treatment target. Yet, measures designed to detect JTC are compromised by a number of limitations. We aimed to address some of these shortcomings with a new video-based "Whodunit task" among participants scoring high and low on the Community Assessment of Psychic Experiences (CAPE). We recruited a large sample (N = 979) from the general population who were divided into subgroups high vs. low on psychotic-like experiences (PLE), matched for depression and background characteristics. In the Whodunit task, participants were asked to rate the likelihood that one out of six suspects was the perpetrator of a crime (deliberately ambiguous with no clear clues until the end). The primary measure was the number of sequences-to-decision (STD). In line with the hypothesis, participants scoring high on the CAPE positive subscale displayed significantly lower STD and a higher rate of JTC. Response confidence in the assessments was elevated in the PLE-High group. The number of overall decisions was also significantly elevated for the PLE-High group. No group differences were found when comparing those scoring high versus low on depression. The STD index correlated significantly with a corresponding index from another JTC task. The study presents a new paradigm for the measurement of data gathering in the schizophrenia spectrum. Speaking to its validity, the Whodunit task was correlated with another JTC measure. Future research should test abbreviated versions of the paradigm, preferably using multiple trials with differing topics/emotional themes.

Sweet spot in music-Is predictability preferred among persons with psychotic-like experiences or autistic traits?

People prefer music with an intermediate level of predictability; not so predictable as to be boring, yet not so unpredictable that it ceases to be music. This sweet spot for predictability varies due to differences in the perception of predictability. The symptoms of both psychosis and Autism Spectrum Disorder have been attributed to overestimation of uncertainty, which predicts a preference for predictable stimuli and environments. In a pre-registered study, we tested this prediction by investigating whether psychotic and autistic traits were associated with a higher preference for predictability in music. Participants from the general population were presented with twenty-nine pre-composed music excerpts, scored on their complexity by musical experts. A participant's preferred level of predictability corresponded to the peak of the inverted U-shaped curve between music complexity and liking (i.e., a Wundt curve). We found that the sweet spot for predictability did indeed vary between individuals. Contrary to predictions, we did not find support for these variations being associated with autistic and psychotic traits. The findings are discussed in the context of the Wundt curve and the use of naturalistic stimuli. We also provide recommendations for further exploration.

Antipsychotic-Related Stigma and the Impact on Treatment Choices: A Systematic Review and Framework Synthesis

BACKGROUND

Antipsychotics are a class of medications primarily used to treat individuals with psychotic disorders. They have also been indicated for patients with other psychiatric conditions, such as post-traumatic stress disorder and major depressive disorder. Non-adherence is prominent amongst individuals prescribed antipsychotics, with medication-related self-stigma and social stigma identified as major factors. No previous reviews have focused on stigma associated specifically with antipsychotic medication. This systematic literature review aimed to synthesise evidence on the prevalence of stigmatising attitudes and behaviours related to antipsychotic treatment and understand their impact on antipsychotic treatment initiation and continuation.

METHODS

Two independent reviewers screened studies from databases, congress proceedings, ClinicalTrials.gov, and PsychU.org; relevant studies reported quantitative or qualitative data on antipsychotic-related stigma in adults with psychotic disorders, mood disorders, borderline personality disorder or anxiety disorders, or healthcare providers or caregivers of these patients, and any impact on treatment. Framework synthesis facilitated extraction and synthesis of relevant information; quantitative and qualitative data were coded and indexed against a pre-specified thematic framework by two independent reviewers.

RESULTS

Forty-five articles reporting on 40 unique studies were included; 22 reported quantitative data, 16 reported qualitative data, and two reported quantitative and qualitative data relating to antipsychotic-related stigma. Framework synthesis identified four themes: 1) impact of antipsychotic treatment on a) social stigma or b) self-stigma; 2) impact of side effects of antipsychotic treatment on a) social stigma or b) self-stigma; 3) impact of route of administration of antipsychotic treatment on stigma; 4) impact of stigma on the use of antipsychotics.

CONCLUSION

This systematic literature review found that antipsychotic-related social and self-stigma is a factor in non-adherence to antipsychotics. Further research should examine stigma in a wider range of patients and the extent to which clinicians' treatment decisions are impacted by the potential stigma associated with antipsychotic medications.

Autistic traits as a potential confounding factor in the relationship between schizotypy and conspiracy beliefs

BACKGROUND

Conspiracy Theories (CT) are complex belief systems that view the world as being manipulated by multiple actors collaborating in the pursuit of malevolent goals. Although culture, education and sociological factors have been implicated in their development, psychological factors are recognized as important. Certain individual differences, including schizotypy and cognitive processing style, have been shown to make some individuals susceptible to CTs. However, the finding that schizotypy often co-occurs with autism spectrum disorder raises a question as to the relative and potentially confounding role of autistic traits in increasing vulnerability to CT beliefs.

METHOD

A total of 508 adults were recruited from an international online panel. The study included measures of conspiracy beliefs, schizotypy and autistic traits as well as measures of information searching and cognitive style.

RESULTS

The results confirmed that both autistic and schizotypy traits were positively associated with CT beliefs, but that schizotypy traits were the strongest predictor. Exploratory analyses of cognitive style measures indicated potential avenues for further investigation in relation in differences in cognitive processes that might underlie the development of CTs for in people with autistic traits as opposed to schizotypal traits.

LIMITATIONS

The study was based on a self-report methodology and did not utilise a clinical sample.

CONCLUSION

Both schizotypal and autistic traits are reliable predictors of conspiracy beliefs, but schizotypy appears to be the stronger predictor and that autistic traits are not a strong confounding factor in this relationship. However, autistic traits may pose an additional risk factor for CT beliefs.

Analysis of Medication Adherence and Its Influencing Factors in Patients with Schizophrenia in the Chinese Institutional Environment

BACKGROUND

Factors related to medication adherence in patients with schizophrenia have always been key to the treatment and rehabilitation of these patients. However, the treatment modes in different countries are not the same, and there is no research on the factors influencing medication adherence under different mental health service modes.

OBJECTIVES

The purpose of this study was to explore medication adherence and its influencing factors in patients with schizophrenia in the Chinese institutional environment.

METHODS

We conducted a cross-sectional study of hospitalized persons living with schizophrenia from November 2018 to January 2019. A systematic sampling method was used to select 217 hospitalized persons living with schizophrenia. The Medication Adherence Rating Scale (MARS), Positive and Negative Syndrome Scale (PANSS), General Self-Efficacy Scale (GSES), Schizophrenia Quality of Life Scale (SQLS), and Scale of Social Skills for Psychiatric Inpatients (SSPI) were used to explore medication compliance and its influencing factors in the Chinese institutional environment.

RESULTS

The descriptive analysis and ANOVA showed that there were no significant differences in medication adherence when assessed by demographic characteristics such as sex, marital status, and education level (p > 0.05). A correlation analysis showed that there was no significant correlation between medication adherence and mental symptoms (p > 0.05) but that there was a positive correlation with self-efficacy, quality of life, and activities of daily living (p < 0.01). The linear regression analysis showed that self-efficacy, psychosocial factors, symptoms/side effects, and activities of daily living had significant effects on medication adherence (F = 30.210, p < 0.001).

CONCLUSIONS

Our findings show that the self-efficacy, quality of life, and social function of patients with schizophrenia are important self-factors influencing medication adherence in the Chinese institutional environment.

A rating scale to inform successful discontinuation of antipsychotics and antidepressants

Practitioners lack guidance on how to support discontinuation of psychotropic medication. An understanding of what constitutes discontinuation success that encompasses the patients' perspective could advance knowledge in this clinically relevant area. Here, we report the development and validation of a scale to assess subjective discontinuation success. Participants who attempted discontinuing antidepressants and/or antipsychotics during the past 5 years (n = 396) completed a questionnaire on subjective discontinuation success (Discontinuation Success Scale, DSS) developed in consultation with people with lived experience of discontinuation. Construct validity was tested by exploratory and confirmatory factor analysis. Criterion validity was tested by assessing DSS-scores' associations with objective success (i.e., full cessation, reduced dose) in combination with scoring above a predefined criterion on the Well-Being Index. Factor analyses yielded a three-dimensional scale reflecting subjective discontinuation success, positive effects, and negative effects of discontinuation. A 24-item DSS demonstrated sufficient model fit for the participants discontinuing antidepressants or antipsychotics, respectively. Significant associations with objective success and well-being were found. Participants who had achieved full cessation and scored high on well-being reached the highest DSS scores. The DSS is a viable tool for future research aimed at identifying predictors of discontinuation success in order to inform recommendations related to discontinuation.

Daily functioning and symptom factors contributing to attitudes toward antipsychotic treatment and treatment adherence in outpatients with schizophrenia spectrum disorders

BACKGROUND

Poor adherence and negative attitudes to treatment are common clinical problems when treating psychotic disorders. This study investigated how schizophrenia core symptoms and daily functioning affect treatment adherence and attitudes toward antipsychotic medication and to compare patients using clozapine or other antipsychotics.

METHOD

A cross-sectional study with data from 275 patients diagnosed with schizophrenia spectrum disorder. Patients adherence, attitudes, insight and side-effects were evaluated using the Attitudes toward Neuroleptic Treatment scale. Overall symptomology was measured using the Brief Psychiatric Rating Scale (BPRS), the Health of the Nation Outcome Scale (HoNOS). The functioning was assessed using activities of daily living scale, instrumental activities of daily living scale and social functioning of daily living scale.

RESULTS

Self-reported treatment adherence was high. Of the patients, 83% reported using at least 75% of the prescribed medication. Having more symptoms was related with more negative attitude towards treatment. There was a modest association with functioning and treatment adherence and attitude toward antipsychotic treatment. Attitudes affected on adherence in non-clozapine but not in clozapine groups.

CONCLUSION

Early detection of non-adherence is difficult. Systematic evaluation of attitudes toward the treatment could be one way to assess this problem, along with optimized medication, prompt evaluation of side effects and flexible use of psychosocial treatments.

The Importance of Suicide Risk Formulation in Schizophrenia

Suicide is a cause of early mortality in nearly 5% of patients with schizophrenia, and 25-50% of patients with schizophrenia attempt suicide in their lifetime. Evidence points to numerous individual, clinical, social, and psychological risk factors for suicide in patients with schizophrenia. Although recognizing suicidal risk factors in schizophrenia is extremely important in suicidal risk assessment, we have recently witnessed a change in suicide risk management that shifts the focus from suicide risk assessment to suicide risk formulation. Suicide risk formulation is dependent on the data gathered in the suicide risk assessment and assigns a level of suicide risk that is indispensable for the choice of treatment and the management of patients with a high suicidal risk. In this article, we extend the suicide risk formulation model to patients with schizophrenia. Suicide risk formulation results from four different areas that help clinicians collect as much information as possible for the management of suicidal risk. The four distinct judgments comprise risk status (the risk relating to the specific group to which the patient belongs), risk state (the risk for the person compared with his baseline or another reference point in the course of his life), available resources (on whom the person can count during a crisis) and foreseeable events (which can exacerbate the crisis). In schizophrenia, the suicide risk formulation model allows the clinician to evaluate in depth the clinical context of the patient, the patient's own history and patient-specific opportunities for better choosing and applying suicide prevention strategies.

Computational Mechanism for the Effect of Psychosis Community Treatment: A Conceptual Review From Neurobiology to Social Interaction

The computational underpinnings of positive psychotic symptoms have recently received significant attention. Candidate mechanisms include some combination of maladaptive priors and reduced updating of these priors during perception. A potential benefit of models with such mechanisms is their ability to link multiple levels of explanation, from the neurobiological to the social, allowing us to provide an information processing-based account of how specific alterations in self-self and self-environment interactions result in the experience of positive symptoms. This is key to improving how we understand the experience of psychosis. Moreover, it points us toward more comprehensive avenues for therapeutic research by providing a putative mechanism that could allow for the generation of new treatments from first principles. In order to demonstrate this, our conceptual paper will discuss the application of the insights from previous computational models to an important and complex set of evidence-based clinical interventions with strong social elements, such as coordinated specialty care clinics (CSC) in early psychosis and assertive community treatment (ACT). These interventions may include but also go beyond psychopharmacology, providing, we argue, structure and predictability for patients experiencing psychosis. We develop the argument that this structure and predictability directly counteract the relatively low precision afforded to sensory information in psychosis, while also providing the patient more access to external cognitive resources in the form of providers and the structure of the programs themselves. We discuss how computational models explain the resulting reduction in symptoms, as well as the predictions these models make about potential responses of patients to modifications or to different variations of these interventions. We also link, via the framework of computational models, the patient's experiences and response to interventions to putative neurobiology.

COVID-19-related conspiracy beliefs and their relationship with perceived stress and pre-existing conspiracy beliefs

Previous studies have down that erroneous Conspiracy Theory (CT) beliefs develop more strongly in people who have underlying conspiratorial reasoning styles and psychopathological traits and particularly when they are faced with stressful external events (Swami et al., 2013; van Prooijen, 2018). In this study, we test this proposition by examining the individual differences associated with the development of COVID-19-related CT beliefs during the pandemic. A total of 660 adults completed a survey that captured COVID–related CT beliefs and broader conspiracy beliefs, education, perceived stress and attitudes towards government responses. The results showed that COVID-19 related CT beliefs were: strongly related to broader CT beliefs, higher in those with lower levels of education; and, positively (although weakly) correlated with more negative attitudes towards government responses. However, no relationship was found between COVID-19 beliefs and self-reported stress. These findings hold implications for why some people are more likely to be resistant to public health interventions relating to COVID-19. The findings encourage more detailed exploration of the causes and sources of CTs and, in particular, the role of social media use and other information sources in the development and perpetuation of health-related CT beliefs.

Promoting insight into delusions: Issues and challenges in therapy

During recent years, the role of non-pharmacological interventions in the management of psychotic symptoms, including delusions, has received increased recognition. However, a few factors such as the client's cognitive impairments and poor insight into the illness may create challenges for the therapist in conducting these interventions. Present paper discusses some of these issues and the steps a therapist can take to deal with them.

Pill or needle? Determinants of the preference for long-acting injection over oral treatment in people facing chronic illness

Although long-acting injection (LAI) is presented as first line treatment option for patients with psychosis, negative attitudes toward this galenic negatively impact the selection of this treatment option. However, these negative attitudes may not be confined to patients but also observed in the general population. A web-based study on 1807 participants was conducted during which participants imagined that they had a particular chronic illness based on clinical vignettes (mental illnesses: schizophrenia, depression; somatic illnesses: multiple sclerosis, rheumatoid arthritis). The frequency of relapse and the intensity of symptoms were experimentally manipulated in the vignettes. Participants rated their subjective distress associated with each vignette, their belief in the effectiveness of treatment, and their treatment preference regarding medication. We examined under which conditions LAI was preferred over pills. Statistical analyses were performed using Bayesian methods. Results showed that participants preferred LAI over pills in 40.5% to 50.8% of cases. LAI was more preferred for illnesses with low frequency of relapse, low subjective distress, and for somatic than for mental illnesses. The perceived advantage for LAI over pills and the belief about the better efficiency of LAI were the main factors that drove the preference for LAI. Keeping in mind some advantages of LAI, the public negative representations of injections might partially influence patients' prejudices against LAI. These attitudes should be named and discussed with the patients when LAI seems to represent a relevant therapeutic option.

Psychotropic medication non-adherence and its associated factors among patients with major psychiatric disorders: a systematic review and meta-analysis

BACKGROUND

Major psychiatric disorders are growing public health concern that attributed 14% of the global burden of diseases. The management of major psychiatric disorders is challenging mainly due to medication non-adherence. However, there is a paucity of summarized evidence on the prevalence of psychotropic medication non-adherence and associated factors. Therefore, we aimed to summarize existing primary studies' finding to determine the pooled prevalence and factors associated with psychotropic medication non-adherence.

METHODS

A total of 4504 studies written in English until December 31, 2017, were searched from the main databases (n = 3125) (PubMed (MEDLINE), Embase, CINAHL, PsycINFO, and Web of Science) and other relevant sources (mainly from Google Scholar, n = 1379). Study selection, screening, and data extraction were carried out independently by two authors. Observational studies that had been conducted among adult patients (18 years and older) with major psychiatric disorders were eligible for the selection process. Critical appraisal of the included studies was carried out using the Newcastle Ottawa Scale. Systematic synthesis of the studies was carried out to summarize factors associated with psychotropic medication non-adherence. Meta-analysis was carried using Stata 14. Random effects model was used to compute the pooled prevalence, and sub-group analysis at 95% confidence interval.

RESULTS

Forty-six studies were included in the systematic review. Of these, 35 studies (schizophrenia (n = 9), depressive (n = 16), and bipolar (n = 10) disorders) were included in the meta-analysis. Overall, 49% of major psychiatric disorder patients were non-adherent to their psychotropic medication. Of these, psychotropic medication non-adherence for schizophrenia, major depressive disorders, and bipolar disorders were 56%, 50%, and 44%, respectively. Individual patient's behaviors, lack of social support, clinical or treatment and illness-related, and health system factors influenced psychotropic medication non-adherence.

CONCLUSION

Psychotropic medication non-adherence was high. It was influenced by various factors operating at different levels. Therefore, comprehensive intervention strategies should be designed to address factors associated with psychotropic medication non-adherence.

Predicting relapse with residual symptoms in schizophrenia: A secondary analysis of the PROACTIVE trial

INTRODUCTION

Little attention has been paid to the contribution of individual residual symptom to predict relapse in patients with schizophrenia receiving oral or long-acting injectable (LAI) antipsychotics.

METHOD

We used the data from the Preventing Relapse on Oral Antipsychotics Compared to Injectables - Evaluating Efficacy (PROACTIVE) study, in which 305 outpatients with schizophrenia were randomly allocated to either biweekly LAI-risperidone (LAI-R) or daily oral second-generation antipsychotics (SGA) and assessed for up to 30 months. Baseline individual symptoms that could predict subsequent relapse were identified, using a Cox proportional hazards model. Moreover, among those who relapsed during the study (n = 73), individual symptoms were compared between baseline and biweekly ratings 8 to 2 weeks before relapse, using the linear mixed model.

RESULTS

A greater score in grandiosity at baseline was significantly associated with subsequent relapse (adjusted HR = 1.24, p = 0.006). When the two treatment groups were separately analyzed, more severe grandiosity (adjusted HR = 1.43, p = 0.003) and less severe hallucinatory behavior (adjusted HR = 0.70, p = 0.013) at baseline were significantly associated with relapse in the oral SGA group, but none was identified in the LAI-R group. Emotional withdrawal was significantly worse 8 and 2 weeks before relapse compared to the baseline (p = 0.032 and p = 0.043, respectively).

DISCUSSION

More severe grandiosity and less hallucination may have led to more frequent relapses in patients with schizophrenia receiving oral antipsychotics, which was not a case in those receiving LAI-R. The exploratory analysis indicates an increase in emotional withdrawal before relapse may be a useful marker for earlier interventions to possibly avert relapse.

Factors Associated with Medication Adherence Among Patients with Severe Mental Disorders in China: A Propensity Score Matching Study

OBJECTIVE

The 686 project provides free essential drugs and follow-up for poor SMD patients, with the purpose of improving patients' medication adherence and reducing the occurrence of dangerous behaviors. The objective of this research was to determine the factors that influence medication adherence in patients with severe mental disorders (SMD) and analyze whether the 686 program significantly improved patient medication adherence.

METHODS

This study was conducted among SMD patients in 686 project and non-project SMD patients in the same community in 11 cities in Shandong Province of China. The data collected included basic patient information and disease treatment information. Medication adherence was divided into good adherence and poor adherence. Propensity score matching (1:1 match) was performed to adjust for differences in baseline characteristics.

RESULTS

One thousand two hundred ninety-two patients receiving free medication assistance policy (686 project group) and 1292 non-policy patients (control group) were analyzed. Patients who received the 686 project group had significantly better medication adherence than the non-policy group patients (92.6% vs.61.2%). Older age and consolidation period were associated with poor adherence, and education level was the positive determinant for adherence.

CONCLUSION

The 686 project could improve medication adherence to patients with SMD. Additional research will pay attention to medication adherence of patients who are elderly, in consolidation period and lower education levels. It should strengthen the guidance and supervision of patients' medication and strengthen the health education of family members and patients.

The Perspective of Forensic Inpatients With Psychotic Disorders on Protective Factors Against Risk of Violent Behavior

Background: Little is known about the opinions of forensic inpatients with psychotic disorders like schizophrenia on factors likely to prevent or decrease future violent behavior. Aims: To understand the perspectives of forensic inpatients with psychotic disorders on protective factors against risk of violent behavior and compare them to factors identified by professional staff. Method: Using the Structured Assessment of Protective Factors (SAPROF) checklist for self-appraisal of violence risk, we conducted semi-structured interviews with 32 inpatients of the Medical Treatment and Supervision Act Ward and compared the results with those of professionals. Results: Inpatients scored higher in the SAPROF total score, the motivational factors of "life goals" and "motivation for treatment," and the protective level in general. Inpatients scored themselves lower in risk level than professionals. The degree of agreement between service users' and professionals' evaluations was low for all categories except external factors. Inpatients prioritized "life goals," "self-control," and "medication" as the top three key strengths currently preventing violent behavior, whereas the professionals selected "life goals" less often. The top three important future goals for preventing future violence selected by inpatients were "work," "intimate relationships," and "life goals," with the former two being selected significantly less often by the professionals. Conclusions: This is the first study to shed light on Japanese forensic inpatients' perspectives about preventing future violent behavior. Despite professionals' underestimation, inpatients viewed themselves as having high motivation for treatment and positive life goals. Inpatients prioritized personal values such as life goals, work, and intimate relationships, whereas professionals prioritized understanding, treating, and observing the disease. Our findings are consistent with past reports on patients' and clinicians' perspectives. Awareness of such gaps in perceptions can help build fruitful therapeutic alliances. We discuss the implications in terms of treatment, how to address the gap therapeutically, and how to design treatment accordingly. Directions for future research are also discussed.

Predicting therapy success from the outset: The moderating effect of insight into the illness on metacognitive psychotherapy outcome among persons with schizophrenia

The degree to which a person recognizes their mental disorder, attributes symptoms to the disorder, and recognizes that treatment may be necessary is frequently referred to as clinical insight. The current study investigates whether clinical insight at baseline moderates the effects on metacognitive capacity of 40 sessions of metacognitive reflection and insight therapy among 35 participants with psychosis. Findings showed that clinical insight did not predict drop-out from therapy. Multilevel analyses provided support for our hypotheses that insight at baseline significantly moderates metacognitive gains at both postmeasurement and follow-up. Our findings demonstrate that lacking clinical insight substantially hampers the effect of this psychosocial intervention. We posit that research efforts should shift from developing interventions, which enhance clinical insight, to interventions, which are effective in absence of clinical insight.

The Multiple Dimensions of Insight in Schizophrenia-Spectrum Disorders

The concept of insight is used to indicate the propensity of patients with schizophrenia and other severe mental disorders to recognize their illness and engage in treatment. Thus, insight may have notable consequences for the ill individual: Those who lack insight are at higher risk of nonadherence to treatments, negative clinical outcomes, and worse community functioning. Although insight is an intuitive concept, its essence remains difficult to capture. However, many rating scales are available to aid assessment, both for clinical and research purposes. Insight cannot be reduced to a symptom, a psychological mechanism, or a neuropsychological function. It is likely to have dynamic relationships with all these dimensions and with responses to personal events and contextual factors. In particular, social consequences of mental illness and explanatory models that are alternative to the medical model may fundamentally shape insight and treatment choice. Moreover, the cultural or individual stigmatization of mental illness may turn the acquisition of insight into a painful event and increase the risk of depression. Clinicians need to carefully evaluate and promote insight through a personalized approach to aid patient process of care and personal growth.

Retrospective Accounts of the Process of Using and Discontinuing Psychiatric Medication

Refusal to take psychiatric medication as prescribed is often considered negative, harmful, and even reflective of a sign of one's illness. However, recent research from diverse sources has challenged this axiom. The current study investigated the reasons, processes, experiences, and perceived impacts of medication discontinuation. The study was carried out using the narrative approach to life stories method. Participants were 12 women and 9 men who had discontinued their prescribed medication following psychiatric hospitalization. Four main themes were revealed in the data analysis: (a) the experience with medication, (b) the process of discontinuing medication, (c) elements that helped achieve successful medication discontinuation, and (d) the perceived impact of medication discontinuation. Our findings challenge the widespread notion that discontinuing psychiatric medication is necessarily negative and suggest that, for some, it is a legitimate and meaningful life choice.

Overlap and distinction between measures of insight and self-stigma

Multiple studies on insight into one's illness and self-stigma among patients with serious mental illness and their relatives have shown that these constructs are related to one another and that they affect outcome. However, a critical exploration of the items used to assess both constructs raises questions with regard to the possible overlapping and centrality of items. The current study used five different samples to explore the possible overlap and distinction between insight and self-stigma, and to identify central items, via network analyses and principal component factor analysis. Findings from the network analyses showed overlap between insight and self-stigma exist with a relatively clearer observational distinction between the constructs among the two parent samples in comparison to the patient samples. Principal component factor analysis constrained to two factors showed that a relatively high percentage of items were not loaded on either factor, and in a few datasets, several insight items were loaded on the self-stigma scale and vice versa. The author discusses implications for research and calls for rethinking the way insight is assessed. Clinical implications are also discussed in reference to central items of social isolation, future worries and stereotype endorsement among the different study groups.

Exploring predictors of medication adherence among inpatients with schizophrenia in Singapore's mental health settings: A non-experimental study

Schizophrenia is a mental disorder, which is marked by frequent relapses. The main reason for relapse is nonadherence to antipsychotics. A cross-sectional, correlational research study was conducted with a convenience sample of 92 participants. The primary aim of this study was to explore the predictors of medication adherence among inpatients with schizophrenia hospitalised at tertiary hospitals in Singapore. Post-hoc analysis revealed that insight, religion, side effects, types of antipsychotics, social support from significant others, nurse-client relationship, were significant predictive factors. Results from this study added knowledge to the nursing literature about medication adherence of schizophrenia patients and in Singapore setting.

Reducing distress and improving social functioning in daily life in people with auditory verbal hallucinations: study protocol for the 'Temstem' randomised controlled trial

INTRODUCTION

Auditory verbal hallucinations (AVH) are prevalent experiences that can induce distress and impede social functioning. While most voice hearers benefit from antipsychotic medication or cognitive-behavioural therapy, additional effective interventions are needed to reduce the burden of experiencing AVH. 'Temstem' is an easily accessible and useable smartphone application that was developed by designers in close cooperation with voice hearers and experts. By using language games, Temstem aims to reduce distress and improve social functioning.

METHODS

This is a single-blind multicentre randomised controlled trial with two arms: 'Temstem+AVH monitoring' versus 'AVH monitoring' (total n=100). Participants are adult patients who suffer daily from AVH and will be recruited in outpatient units. Primary assessment in daily life is made by the Experience Sampling Method (ESM) and daily monitoring with the PsyMate app. During an ESM period of 6 days, participants assess their mental state (including AVH and context) several times a day by filling in short questionnaires. There are three 6-day ESM periods: at baseline (week 0-1), post-treatment (weeks 5-6) and follow-up (weeks 9-10). In addition, during the entire 10-week study period, all participants monitor their AVH two times a day with a short assessment via the PsyMate app. Participants in the Temstem+AVH monitoring condition are provided with the Temstem app from week 1 to 6. Other assessments made at baseline, post-treatment and follow-up are based on questionnaires and a clinical interview.

ETHICS AND DISSEMINATION

The results from this study will provide an evaluation of the effectiveness of Temstem, a non-invasive and easily accessible app for voice hearers, and insight into the determinants of optimal use. Results will be disseminated unreservedly, irrespective of the magnitude or direction of the effects. This study protocol was approved by the Medical Ethics Committee of the VU University Medical Centre (METC number: 2015.435/NL53684.029.15).

Embracing Psychosis: A Cognitive Insight Intervention Improves Personal Narratives and Meaning-Making in Patients With Schizophrenia

Schizophrenia is a complex psychiatric disorder with unknown and presumably heterogeneous etiology. While the disorder can have various outcomes, research is predominantly "deficit-oriented" emphasizing the hardship that the disorder inflicts on sufferers as well as their families and society. Beyond symptom reduction, imparting patients with hope and meaning in life is increasingly considered an important treatment target, which may raise self-esteem, and reduce self-stigma and suicidal ideation. The present study compared a psychotherapeutic treatment aimed at improving cognitive insight, individualized metacognitive intervention (MCT+), with an active control in order to elucidate if personal meaning-making and hope can be improved in patients with psychosis across time. A total of 92 patients were randomized to either individualized metacognitive therapy (MCT+) or CogPack (neuropsychological training) and followed up for up to 6 months. The "Subjective Sense in Psychosis Questionnaire" (SUSE) was administered which covers different salutogenetic vs pathogenetic views of the disorder, valence of symptom experiences and the consequences of psychosis. Patients in the MCT+ group showed a significant positive shift in attitudes towards the consequences of their illness over time relative to patients in the active control condition. There was some evidence that MCT+ also enhanced meaning-making. The perceived negative consequences of psychosis were highly correlated with depression and low self-esteem, as well as suicidality. The study shows that a cognitive insight training can improve meaning-making in patients and help them come to terms with their diagnosis.

Do depressive symptoms predict paranoia or vice versa?

BACKGROUND AND OBJECTIVES

Affective versus nonaffective psychoses are today no longer regarded as mutually exclusive disorders. Theorists have recently highlighted the role of affective symptoms in the formation of paranoid beliefs, particularly negative beliefs about the self, interpersonal sensitivity, sleep disturbances, and worrying, which exist along a continuum in the general population. For the present study, we tested the bidirectional causal relationships between paranoia and affect.

METHOD

A large population sample (N = 2,357) was examined at three time-points (baseline, six months, two years) as to the severity of subclinical paranoid beliefs (Paranoia Checklist, PCL) and depressive symptoms (Patient Health Questionnaire-9, PHQ-9). Worrying and avoidance were measured with items from the Maladaptive and Adaptive Coping Style Questionnaire (MAX).

RESULTS

Depression and paranoid symptoms were strongly cross-sectionally related (r = 0.69) and showed high stability (r > 0.72). Depressive symptoms at T2 predicted paranoid symptoms at T3 (beta = 0.16; no significant relationship from T1 to T2), whereas paranoid symptoms predicted depressive symptoms from T1 to T2 (beta = 0.09; no significant relationship from T2 to T3).

LIMITATIONS

Results should be replicated in a sample of paranoid patients, as risk factors for subclinical versus manifest paranoia may differ. Some constructs were measured with single items derived from a new scale.

CONCLUSIONS

The predictive association of depression to subsequent paranoia was small and confined to the long interval from T2 to T3. Treatments should target both paranoia and depression - irrespective of their causal relationship - particularly as patients with psychosis consider treatment of their emotional problems a priority.

A two-stage cognitive theory of the positive symptoms of psychosis. Highlighting the role of lowered decision thresholds

OBJECTIVES

We outline a two-stage heuristic account for the pathogenesis of the positive symptoms of psychosis.

METHODS

A narrative review on the empirical evidence of the liberal acceptance (LA) account of positive symptoms is presented.

HYPOTHESIS

At the heart of our theory is the idea that psychosis is characterized by a lowered decision threshold, which results in the premature acceptance of hypotheses that a nonpsychotic individual would reject. Once the hypothesis is judged as valid, counterevidence is not sought anymore due to a bias against disconfirmatory evidence as well as confirmation biases, consolidating the false hypothesis. As a result of LA, confidence in errors is enhanced relative to controls. Subjective probabilities are initially low for hypotheses in individuals with delusions, and delusional ideas at stage 1 (belief formation) are often fragile. In the course of the second stage (belief maintenance), fleeting delusional ideas evolve into fixed false beliefs, particularly if the delusional idea is congruent with the emotional state and provides "meaning". LA may also contribute to hallucinations through a misattribution of (partially) normal sensory phenomena. Interventions such as metacognitive training that aim to "plant the seeds of doubt" decrease positive symptoms by encouraging individuals to seek more information and to attenuate confidence. The effect of antipsychotic medication is explained by its doubt-inducing properties.

LIMITATIONS

The model needs to be confirmed by longitudinal designs that allow an examination of causal relationships. Evidence is currently weak for hallucinations.

CONCLUSIONS

The theory may account for positive symptoms in a subgroup of patients. Future directions are outlined.

Would I take antipsychotics, if I had psychotic symptoms? Examining determinants of the decision to take antipsychotics

Poor adherence to treatment in schizophrenia is mainly associated to patients-related factors. However, social negative representations of schizophrenia and its treatment may also contribute to patients' decision to take or not to take antipsychotics. A web-based study on 1,807 participants was conducted during which participants imagined that they had a particular chronic illness based on clinical vignettes (mental illnesses: schizophrenia, depression; somatic illnesses: multiple sclerosis, rheumatoid arthritis). Participants rated their subjective distress and perceived social stigma associated with each illness. They also rated the perceived treatability of the illness, their belief in the effectiveness of treatment, and their treatment preference regarding medication. Results show that schizophrenia was considered more distressful, less treatable and associated with higher social stigma than somatic illnesses. Medication was less preferred for treating schizophrenia compared to somatic illnesses. Perceived treatability of illness and belief in the effectiveness of pharmacological treatment were the factors driving preference for medication in schizophrenia and depression, respectively; these factors had weaker influence on preference for medication in somatic illnesses. Our study points out more severe negative representations of mental illnesses in general, and their treatment, particularly schizophrenia. These attitudes are not confined to patients, and may influence patients' decisions to take psychotropic drugs.

The customer is always right? Subjective target symptoms and treatment preferences in patients with psychosis

Clinicians and patients differ concerning the goals of treatment. Eighty individuals with schizophrenia were assessed online about which symptoms they consider the most important for treatment, as well as their experience with different interventions. Treatment of affective and neuropsychological problems was judged as more important than treatment of positive symptoms (p < 0.005). While most individuals had experience with Occupational and Sports Therapy, only a minority had received Cognitive-Behavioral Therapy, Family Therapy, and Psychoeducation with family members before. Patients appraised Talk, Psychoanalytic, and Art Therapy as well as Metacognitive Training as the most helpful treatments. Clinicians should carefully take into consideration patients' preferences, as neglect of consumers' views may compromise outcome and adherence to treatment.

Cognitive Attachment Model of Voices: Evidence Base and Future Implications

There is a robust association between hearing voices and exposure to traumatic events. Identifying mediating mechanisms for this relationship is key to theories of voice hearing and the development of therapies for distressing voices. This paper outlines the Cognitive Attachment model of Voices (CAV), a theoretical model to understand the relationship between earlier interpersonal trauma and distressing voice hearing. The model builds on attachment theory and well-established cognitive models of voices and argues that attachment and dissociative processes are key psychological mechanisms that explain how trauma influences voice hearing. Following the presentation of the model, the paper will review the current state of evidence regarding the proposed mechanisms of vulnerability to voice hearing and maintenance of voice-related distress. This review will include evidence from studies supporting associations between dissociation and voices, followed by details of our own research supporting the role of dissociation in mediating the relationship between trauma and voices and evidence supporting the role of adult attachment in influencing beliefs and relationships that voice hearers can develop with voices. The paper concludes by outlining the key questions that future research needs to address to fully test the model and the clinical implications that arise from the work.

Treatment compliance and noncompliance in psychoses

BACKGROUND

Compliance or noncompliance with treatment significantly influences course and outcome of psychiatric disorders. While noncompliance has been extensively researched, compliance has received less attention. The current study was conducted to elicit reasons for compliance and noncompliance in patients having psychoses attending psychiatric clinics.

MATERIALS AND METHODS

A total of 196 compliant and 150 noncompliant patients were interviewed using self-designed tools to elicit sociodemographic data, details of illness, and treatment. Factors contributing to compliance and noncompliance were grouped under illness-related, clinician-related, medication-related, family-related, and economic-related domains and compared.

RESULTS

Compliance was significantly more in females and middle- and high-socioeconomic status patients. They had less substance use, high physical comorbidity, high attendance in the outpatient department, and better remission. Clinician-related, family-related, and medication-related domains were contributing more to compliance whereas illness-related and economic-related domains seemed to have more bearing on noncompliance.

CONCLUSIONS

Compliance and noncompliance are determined multidimensionally. Domains related to clinician, family, and medications have to be reinforced to enhance compliance. Illness-related and economic domains have to be resolved to reduce noncompliance.

Factors Affecting Medication Adherence Among Adults with Schizophrenia: A Literature Review

This review aimed to summarize empirical evidence concerning factors relating to medication adherence among patients with schizophrenia. A comprehensive search was implemented to recruit articles which met the present eligibility criteria. Twenty-five articles were included whereby only one was a qualitative study. Greater awareness of illness (insight), previous history of medication adherence, positive attitude toward medication, types of atypical antipsychotics, less severe psychotic symptoms, and social support were identified as factors of medication adherence. Knowledge gaps and methodological limitations were also identified. Implications to clinical practice include providing psychoeducation to patients by increasing their knowledge about illness and medication.

Influence of magnesium supplementation on movement side effects related to typical antipsychotic treatment in rats

Chronic use of typical antipsychotic haloperidolis related to movement disturbances such as parkinsonism, akathisia and tardive dyskinesia which have been related to excitotoxicity in extrapyramidal brain areas, requiring their prevention and treatment. In the current study we evaluated the influence of the magnesium on prevention (for 28days before-), reversion (for 12days after-) and concomitant supplementation on haloperidol-induced movement disorders in rats. Sub-chronic haloperidol was related to orofacial dyskinesia (OD) and catalepsy development, increased generation of reactive species (RS) and levels of protein carbonyl (PC) in cortex, striatum and substantia nigra (SN) in all experimental protocols. When provided preventatively, Mg reduced the increase of OD and catalepsy time 14 and 7days after haloperidol administration, respectively. When supplemented after haloperidol-induced OD establishment, Mg reversed this behavior after 12days, while catalepsy was reversed after 6days of Mg supplementation.When Mg was concomitantly supplemented with haloperidol administration, OD and catalepsy were prevented. Moreover, Mg supplementation was able to prevent the RS generation in both cortex and SN, reducing PC levels in all brain areas evaluated. When supplemented after haloperidol, Mg reversed RS generation in cortex and striatum, decreasing PC levels in SN and striatum.The co-administration of haloperidol and Mg supplementation prevented RS generation in cortex, striatum and SN, and PC levels in the SN.These outcomes indicate that Mg supplementation may be a useful alternative to prevent movement disturbances resulting of classic antipsychotic pharmacotherapy as haloperidol.

The impact of negative treatment experiences on persistent refusal of antipsychotics

AIMS

We investigate reasons for persistent medication refusal in schizophrenia spectrum disorders and test whether factors that speak for a rational decision, such as negative experiences with medication or low symptom distress predict medication refusal, even after taking differences in insight into account.

METHOD

We included 45 participants with schizophrenia spectrum disorders, of which 20 had refused antipsychotic medication for at least three months and assessed reasons for taking or not taking medication, labeling condition as mental disorder ("insight"), experiences with the previous treatments, symptoms and symptom distress, positive and negative consequences and experiences of psychosis, causal beliefs, therapeutic relationships with previous clinicians and attitudes towards medication.

RESULTS

Groups did not differ in symptom severity but medication refusers reported significantly less insight, less satisfaction with their most-recent psychiatrist and with previous medication, and more negative beliefs about harmful effects of medication. They also felt less informed about medication. After controlling for insight, the perceived helpfulness of the previous treating psychiatrist (OR=0.30, z=5.58, p=0.018) and of previous medication (OR=0.27, z=6.87, p=0.009) and feeling insufficiently informed about medication (OR=0.53, z=3. 85, p=0.050) significantly predicted medication discontinuation.

CONCLUSIONS

Building rapport with patients with a different view of the nature of their condition and encouraging informed decisions on medication are likely to improve medication adherence. However, the findings also suggest that refusing medication after a phase of initial adherence is also the consequence of negative experiences with medication and could result from weighing the pros against the cons.

Experiences of continued presence: On the practical consequences of 'hallucinations' in bereavement

OBJECTIVES

We document the properties of experiences of continued presence (ECPs) helping to resolve controversies about their significance.

METHOD

We used qualitative methods in data collection and analysis. This enabled us to document the properties of ECPs. Narrative biographic interviews were carried out with 17 bereaved informants, and conversation analysis was used to identify the sources of meaning and functions of these experiences.

RESULTS

Our informants heard voices of the deceased, saw their images, felt their touch, and sometimes felt their presence unspecified in any of the senses. Analysis revealed that ECPs were meaningfully connected to the immediate environments in which they happened but also to the personal histories of the bereaved. The narratives reveal helpful and destructive potentials of these experiences. In all cases, the functions relied on the relationship with the deceased.

CONCLUSIONS

The authors warn against oversimplification of ECPs, as significantly contrasting practical consequences commonly occurred within as well as between cases. The findings support the use of talking therapies based on personal meanings to help those disturbed by their experiences of presence.

PRACTITIONER POINTS

Practitioners should not assume that ECPs are signs of pathology - often they have healing consequences. Where ECPs cause distress, the problem is likely to concern relationship difficulties with the deceased. Therapists can help clients with distressing ECPs by working on the relationship with the deceased.

Self-disorders in individuals with attenuated psychotic symptoms: Contribution of a dysfunction of autobiographical memory

Patients with schizophrenia and people with subclinical psychotic symptoms have difficulties getting a clear and stable representation of their self. The cognitive mechanisms involved in this reduced clarity of self-concept remain poorly understood. The present study examined whether an altered way of thinking or reasoning about one's past may account for the reduced clarity of self-concept in individuals with attenuated psychotic symptoms (APS). An online study comprising 667 participants examined the capacity to give a meaning to past events and to scrutinize autobiographical memory to better understand him/herself. Our results showed that in this sample, individuals with APS (n=49) have a lower clarity of self-concept and a higher tendency to scrutinize autobiographical memory than controls subjects (n=147). A mediation analysis performed on the full sample revealed that the relation between APS and clarity of self-concept was mediated by a tendency to scrutinize autobiographical memory. Our results suggest that the weakness of self-concept, which increases with the intensity of psychotic symptoms, may be related to an altered function of autobiographical memory, so that examining past events may fail to sustain a stable and clear representation of the self when psychotic symptoms increase.

Elucidating the role of Early Maladaptive Schemas for psychotic symptomatology

Although cognitive accounts postulate negative self-concepts as a causal factor in the emergence of psychotic symptoms, little is known about the role of specific self-schemas for psychotic symptomatology. Building on a differentiated and treatment-informed schema model, we aimed to elucidate the role of Early Maladaptive Schemas (EMS) for psychotic symptomatology, particularly their specificity to patients with psychosis and their association with positive versus negative symptoms. We assessed EMS with the Young Schema Questionnaire in patients with psychosis (n=81), patients with depression (n=28) as well as healthy participants (n=60). In the psychosis sample symptoms were rated using the Positive and Negative Syndrome Scale. In comparison to healthy participants, patients with either psychosis or depression showed a higher overall number and intensity of EMS whereas the psychosis and the depression sample did not significantly differ. The overall number and intensity of EMS were significantly associated with positive but not with negative symptoms. Contrary to previous findings, patients with psychosis and patients with depression did not differ in the EMS subscale Mistrust/Abuse. The results suggest that EMS are particularly relevant to positive symptoms. Our findings imply that addressing maladaptive schemas in patients with psychosis by making use of the schema-concept holds potential.

Efficacy and tolerability of topiramate-augmentation therapy for schizophrenia: a systematic review and meta-analysis of randomized controlled trials

This study aimed to perform a comprehensive meta-analysis of topiramate-augmentation therapy in patients with schizophrenia receiving antipsychotic agents. Data published up to June 20, 2016 were obtained from the PubMed, PsycINFO, and Cochrane Library databases. Twelve randomized controlled trials comparing topiramate to placebo or antipsychotic only were included (n=676 patients). The primary outcome was change in overall symptoms. Relative risk (RR) and standardized mean difference (SMD), along with 95% confidence intervals, were calculated using random effects model for each outcome. Topiramate-augmentation therapy was superior to the control for decreasing overall symptoms (SMD -0.55, 95% confidence interval -0.86 to -0.24; P=0.001; I²=55%, eight comparisons, n=380), positive symptoms (SMD -0.4), negative symptoms (SMD -0.47), and Positive and Negative Syndrome Scale general subscale scores (SMD -0.67). Furthermore, topiramate-augmentation therapy decreased weight (SMD -0.69) and body mass index (SMD -0.95) compared with the control. Topiramate was similar to the control with respect to discontinuation due to all causes (RR 1.19), inefficacy (RR 1.71), and adverse events (RR 1.09). Topiramate was associated with higher incidence of paresthesia (RR 2.67) and attention difficulty (RR 8.97) compared with the control. Our results seemed to suggest that topiramate-augmentation therapy improves the psychopathology of schizophrenia with good tolerability and has the additional advantage of weight maintenance. However, because there were some limitations (numbers of studies and patients included in the meta-analysis were small, some studies used completer analysis, Chinese studies were included in the meta-analysis, and studies that had a risk of bias were included in the meta-analysis) in this study, we cannot apply the results of this study in daily clinical practice.

Metacognition-augmented cognitive remediation training reduces jumping to conclusions and overconfidence but not neurocognitive deficits in psychosis

The majority of patients with schizophrenia display neurocognitive deficits (e.g., memory impairment) as well as inflated cognitive biases (e.g., jumping to conclusions). Both cognitive domains are implicated in the pathogenesis of the disorder and are known to compromise functional outcome. At present, there is a dearth of effective treatment options. A total of 90 patients with schizophrenia were recruited online (a diagnosis of schizophrenia had been confirmed in a large subgroup during a previous hospital admission). Subsequent to a baseline assessment encompassing psychopathology, self-reported cognition as well as objective memory and reasoning tests, patients were randomized to one of three conditions: standard cognitive remediation (mybraintraining), metacognition-augmented cognition remediation (CR) condition (variant of mybraintraining which encouraged patients to reduce speed of decision-making and attenuate response confidence when participants made high-confidence judgements and hasty incorrect decisions) and a waitlist control group. Patients were retested after 6 weeks and again 3 months after the second assessment. Groups did not differ on psychopathology and neurocognitive parameters at any timepoint. However, at follow-up the metacognitive-augmented CR group displayed a significant reduction on jumping to conclusions and overconfidence. Treatment adherence correlated with a reduction of depression; gains in the training exercises from the standard mybraintraining condition were correlated with improved objective memory performance. The study suggests that metacognition-augmented CR may ameliorate cognitive biases but not neurocognition. The study ties in well with prior research showing that neurocognitive dysfunctions are rather resistant to change; the failure to detect significant improvement of CR or metacognition-augmented CR on psychopathology and neurocognition over time may partly be attributed to a number of methodological limitations of our study (low psychopathology and chronicity of participants, low “dosage,” narrow range of tests, self-report psychopathology scales).

Mindfulness and relaxation treatment reduce depressive symptoms in individuals with psychosis

Introduction

Self-help is increasingly accepted for the treatment of mental disorders, including psychosis, as both a provisional first step and a way to bridge the large treatment gap. Though mindfulness-based interventions do not belong to first line treatment strategies in psychosis and randomized controlled trials are lacking, encouraging preliminary findings speak for the usefulness of this approach. For the present study, we examined whether patients with psychosis benefit from mindfulness bibliotherapy.

Methods

A sample of 90 patients with psychosis (including a subsample with a verified diagnosis of schizophrenia) took part in the study via the Internet. Following baseline assessment, participants were randomized to either a mindfulness group or a Progressive Muscle Relaxation (PMR) control group and received the respective self-help manual including accompanying audio files. Symptom change was measured six weeks after the baseline assessment with self-rating scales including the Paranoia Checklist. The retention rate was 71%. The quality of the online dataset was confirmed by various strategies (e.g., psychosis lie scale; examination of response biases). The trial was registered at the ISRCTN registry (ISRCTN86762253).

Results

No changes across time or between groups were noted for the Paranoia Checklist. Both conditions showed a decline in depressive and obsessive-compulsive symptoms at a medium effect size (per protocol and intention to treat analyses).

Discussion/conclusion

The study provided partial support for the effectiveness of self-help mindfulness and PMR for depression in psychosis. Whether mindfulness delivered by a licensed therapist might lead to improved treatment adherence and a superior outcome relative to PMR remains to be established. The results underscore that bibliotherapy is a worthwhile approach to narrow the large treatment gap seen in psychosis.

Choosing to use compared to taking medication: the meaning of medication as described by people who experience schizophrenia

PURPOSE

The use of medication is an important aspect within the experience of schizophrenia.

DESIGN AND METHODS

Interviews with 14 people with schizophrenia were analyzed using van Kaam's psychophenomenological method, and findings revealed two opposing and important attitudes toward medication.

FINDINGS

Adopting an attitude of choosing to use prescribed medication means autonomously self-managing medication and taking prescribed medication means feeling challenged and being under external pressure through being told or forced by others and therefore having no personal connection to the details or purpose of medication.

PRACTICE IMPLICATIONS

Nurses need to actively work in partnership to support consumers to take an active stance toward choosing to use medication rather than ensuring consumers take medication.
