A good life with psychosis: rate of positive outcomes in first-episode psychosis at 10-year follow-up.

BACKGROUND: More knowledge about positive outcomes for people with first-episode psychosis (FEP) is needed. An FEP 10-year follow-up study investigated the rate of personal recovery, emotional wellbeing, and clinical recovery in the total sample and between psychotic bipolar spectrum disorders (BD) and schizophrenia spectrum disorders (SZ); and how these positive outcomes overlap. METHODS: FEP participants (n = 128) were re-assessed with structured clinical interviews at 10-year follow-up. Personal recovery was self-rated with the Questionnaire about the Process of Recovery-15-item scale (total score ⩾45). Emotional wellbeing was self-rated with the Life Satisfaction Scale (score ⩾5) and the Temporal Experience of Pleasure Scale (total score ⩾72). Clinical recovery was clinician-rated symptom-remission and adequate functioning (duration minimum 1 year). RESULTS: In FEP, rates of personal recovery (50.8%), life satisfaction (60.9%), and pleasure (57.5%) were higher than clinical recovery (33.6%). Despite lower rates of clinical recovery in SZ compared to BD, they had equal rates of personal recovery and emotional wellbeing. Personal recovery overlapped more with emotional wellbeing than with clinical recovery (χ2). Each participant was assigned to one of eight possible outcome groups depending on the combination of positive outcomes fulfilled. The eight groups collapsed into three equal-sized main outcome groups: 33.6% clinical recovery with personal recovery and/or emotional wellbeing; 34.4% personal recovery and/or emotional wellbeing only; and 32.0% none. CONCLUSIONS: In FEP, 68% had minimum one positive outcome after 10 years, suggesting a good life with psychosis. This knowledge must be shared to instill hope and underlines that subjective and objective positive outcomes must be assessed and targeted in treatment.

Basic self-disturbance trajectories in clinical high risk for psychosis: a one-year follow-up study.

Basic self-disturbance (BSD) has been proposed as a driver of symptom development in schizophrenia spectrum disorders (SSDs). In a one-year follow-up of 32 patients (15-30 years) at putative risk for psychosis, we investigated trajectories of BSD levels from baseline to follow-up, and associations between clinical characteristics at baseline and follow-up, including follow-up levels of BSD (assessed with the EASE). Clinical high risk (CHR) for psychosis status and symptom severity were assessed with the SIPS/SOPS scales and also according to the cognitive basic symptoms high-risk criteria (COGDIS). DSM-IV diagnoses, functioning and other clinical characteristics were assessed with standard clinical instruments. Higher severity of negative symptoms and meeting COGDIS criteria at baseline were associated with higher BSD levels at follow-up. All measured at follow-up, higher BSD levels correlated with higher severity of positive, negative, disorganization and general symptoms, and with a lower level of global functioning. We found higher BSD levels at follow-up in subjects with schizotypal personality disorder (SPD) at baseline (n = 5) and in SSDs at follow-up (n = 12, including nine with SPD). Mean BSD levels decreased significantly from baseline to follow-up, but individual trajectories varied considerably. Increased BSD levels were associated with higher baseline BSD levels, non-remission of positive symptoms and functional decline. Overall, the current study indicates that subgroups in the CHR population with a higher risk of non-remission or deterioration may be identified by supplementing CHR criteria with assessment of BSD and negative symptoms.

COVID-19 lockdown - who cares? The first lockdown from the perspective of relatives of people with severe mental illness.

BACKGROUND: Informal care is vital to many people with severe mental illness under normal circumstances. Little is known about how extraordinary circumstances affect relatives with a family member with mental illness. This study investigated the consequences of the first COVID-19 lockdown in Norway from the perspective of relatives of persons with psychotic- and/or bipolar disorders: What were the challenges and for whom? METHOD: Relatives were invited to complete an online survey shortly after the first lockdown was initiated. Both quantitative and qualitative data were collected concerning experiences of relatives' own and their affected family members' health and situation. Two hundred and seventy-nine relatives completed the survey, mostly mothers and partners. RESULTS: One-third of the relatives reported considerable deterioration in their family members' mental health, and a substantial minority worried about severe self-harm or suicide. Main themes in the qualitative analyses were "Isolation and its effects on mental health", "Worrying about the pandemic and its consequences", "Increased symptomatology" and "Suicide". Being a relative during the lockdown put heavy strain on the relatives' own health, in particular disturbance of sleep, concentration, and the ability to take care of others in the family. Relatives of family members with psychotic bipolar disorder, not currently in treatment, or living with their family experienced the situation especially challenging. CONCLUSIONS: Many relatives found the first lockdown hard for their family. Efforts to integrate relatives' perspectives in health care and contingency plans under normal circumstances could potentially alleviate some of the extra burden experienced by families during extraordinary circumstances.

Locked out during COVID-19 lockdown-an online survey of relatives of people with psychotic and bipolar disorders in Norway.

BACKGROUND: Many relatives of people with psychotic and bipolar disorders experience a high caregiver burden normally. During the first COVID-19 lockdown, mental health services partly shut down in many countries. The impact on relatives is unknown. AIMS: Explore how relatives of people with psychotic and bipolar disorders experienced changes in treatment and service availability for their family member during the first COVID-19 pandemic lockdown in the spring of 2020, and to what extent they perceived information and support to be satisfactory. To help guide future contingency plans, we were also interested in what relatives would prioritize in the event of a future crisis. STUDY SETTING: We distributed an anonymous Norwegian online survey inviting relatives of individuals with psychotic and bipolar disorders. We distributed the survey using social media, through snowball sampling, collecting both quantitative and qualitative data. The survey was available between May and June 2020. We used systematic text condensation to analyse qualitative data. RESULTS: Two hundred and seventy-nine respondents replied, mostly mothers and partners. A majority experienced a reduction in health care for their family member. Most respondents did not receive any support during the lockdown. However, most found the information they received from the mental health services regarding their family members' treatment as sufficient. The qualitative data analysis revealed that relatives experienced three major challenges: reductions in treatment for the family member; reduced organised daily activity for the family member; and an increased caretaker load. In the case of a future lockdown, they would prefer increased access to care compared with a normal situation; increased support for relatives; and enhanced information. CONCLUSIONS: Mental health services in Norway did not manage to meet the needs of patients with severe mental illness and their relatives during the first COVID-19 lockdown. To be better prepared, Norwegian mental health services should consider prioritising infrastructure to ensure access to care and support for both patients and relatives. Digital tools and telephone calls are generally well accepted as substitutes for face-to-face contact.

The poetics of vulnerability: creative writing among young adults in treatment for psychosis in light of Ricoeur's and Kristeva's philosophy of language and subjectivity.

There is a growing interest in the application of creative writing in the treatment of mental illness. Nonpharmacological approaches have shown that access to poetic, creative language can allow for the verbalisation of illness experiences, as well as for self-expressions that can include other facets of the subject outside of the disease. In particular, creative writing in a safe group context has proven to be of particular importance. In this article, we present a pilot on a creative writing group for young adults in treatment for psychosis. We set the texts and experiences from the writing group in dialogue with Paul Ricoeur's and Julia Kristeva's philosophies on poetic language as meaning making and part of subject formation. The focus is on language as materiality and potentiality and on the patient's inherent linguistic resources as founded in a group dynamic. As a whole, the project seeks to give an increased theoretical and empirical understanding of the potentiality of language and creativity for healing experiences, participation and meaning-making processes among vulnerable people. Furthermore, a practice founded in poetic language might critically address both the general and biomedical understanding of the subject and disease.

Opening the curtains for better sleep in psychotic disorders - considerations for improving sleep treatment.

BACKGROUND: Sleep disturbances are prevalent in people with psychosis and are related to several negative outcomes. Recent research indicates that sleep disturbances contribute to the development of psychosis and is therefore an important treatment target. Despite this, a study found that sleep problems in people with psychosis were mostly assessed informally and treated with non-recommended interventions. However, it is uncertain whether these findings reflect local practise or rather status quo for how sleep disturbances in the context of psychosis are approached across different treatment sites. We aimed to replicate this study and investigate how sleep disturbances in people with psychosis are viewed, assessed and treated by clinicians across several mental health services, and the clinicians' perceived barriers to sleep treatment. METHODS: A total of 204 clinicians completed an e-mail survey about sleep problems and psychosis. RESULTS: The main findings were highly consistent with previous research; the clinicians found sleep problems in patients with psychosis to be highly prevalent and with negative consequences. However, structured assessments and the use of recommended treatment interventions were rare. This apparent paradox may at least partly be explained by the clinicians' perceived barriers to sleep treatment, including their declared lack of knowledge about sleep assessment and sleep treatment, and beliefs that sleep treatment is (too) demanding in this population. CONCLUSION: Many patients with psychosis across several treatment sites receive less than optimal sleep treatment. Increasing clinicians' knowledge about adequate sleep treatment and its feasibility for patients with psychotic disorders is therefore imperative.

Cognitive behavior therapy in early psychosis with a focus on depression and low self-esteem: A randomized controlled trial.

BACKGROUND: Patients in early phases of psychosis often struggle with depressive symptoms and low self-esteem. The main aims of the present study were to examine whether cognitive behavior therapy (CBT) compared to treatment as usual (TAU) would reduce depressive symptoms (primary outcome) and increase self-esteem (secondary outcome). Furthermore, we wanted to examine whether CBT reduces symptoms measured with the PANSS (positive, negative, cognitive, or excited symptoms) or increases general functioning compared to TAU. METHODS: A total of 63 early psychosis patients were included and randomly assigned to receive either CBT (maximum 26 sessions) or TAU for a period of up to six months. A linear mixed model was used for longitudinal analysis, with a focus on whether patients in the CBT group or the TAU group changed differently to one another between the baseline and 15-month follow-up. RESULTS: There were no differences between the CBT group and TAU group regarding improvements in depressive symptoms measured with the Calgary Depression Scale for Schizophrenia (P = 0.188) or self-esteem measured with the Rosenberg Self-Esteem Scale (P = 0.580). However, patients in the CBT group improved significantly more on negative symptoms (P = 0.002) and social functioning (P = 0.001). CONCLUSIONS: We did not find CBT to be more effective than TAU in reducing depressive symptoms or increasing self-esteem in patients with early psychosis. However, CBT seems to improve negative symptoms and functioning. These results still need to be replicated in further studies as the present one was merely an exploratory analysis.

Perceived and experienced stigma in first-episode psychosis: A 1-year follow-up study.

OBJECTIVES: Perceived/experienced stigma and its relationship with clinical outcome were investigated across the first year of treatment in a large sample with first-episode psychosis (FEP). METHODS: FEP participants (n=112) in the TOP study were investigated at baseline and 1-year follow-up. Perceived/experienced stigma was measured with items from the World Health Organization Disability Assessment Schedule 2.0 (WHODAS 2.0), assessing problems because of barriers and hindrances, and living with dignity because of attitudes and actions of others. Clinical outcome included: symptoms, global functioning, self-rated disability and self-rated life satisfaction. RESULTS: In the total sample, 46% perceived/experienced stigma at baseline, which decreased significantly to 32% at 1-year follow-up. Perceived/experienced stigma was present in 1/5 at both time-points (Sustained stigma), in 2/5 at only one time-point (Transient stigma), and in 2/5 it was not present at either time-point (No stigma). Compared to the No stigma group, the Sustained stigma group had significantly higher levels of positive, excited and depressive symptoms and self-rated disability, as well as lower levels of global functioning and life satisfaction at 1year follow-up, while the Transient stigma group only had poorer functioning and higher self-rated disability. Yet the outcome variables improved across the first year of treatment in all three stigma groups. CONCLUSION: Perceived/experienced stigma was common in FEP, yet the rate decreased across the first year of treatment. Although there was some clinical improvement across the first year of treatment irrespective of stigma, stigma was related to poorer clinical outcome in a bidirectional manner. This suggests that perceived/experienced stigma is an important target in the early stages of treatment.

Consequences of persistent depression and apathy in first-episode psychosis - A one-year follow-up study.

BACKGROUND: Apathy and depression are prevalent in first-episode psychosis (FEP), have overlapping clinical features and are linked to social dysfunction, with indications that persisting symptoms have an even more negative impact. Our objective was to investigate the prevalence of persisting depression (PD), persisting apathy (PA), to what extent they overlap and their relative associations to functioning during a one-year follow-up. METHODS: One hundred and twenty-five participants with a FEP were recruited, and 88 (70%) were reassessed at follow-up. Functional outcome was assessed with the Global Assessment of Functioning Scale-split version, functioning sub-scale, apathy with the Apathy Evaluation Scale, Clinician version (AES-C), and depression with the Calgary Depression Scale for Schizophrenia (CDSS). Persisting depression was defined as a CDSS sum-score > 7 at baseline and follow-up, and persisting apathy as an AES-C sum-score ≥ 27 at baseline and follow-up. Multiple linear regression analyses were used to investigate symptoms' contributions to functioning. Differences in functioning between groups were explored with Kruskal-Wallis test and Mann-Whitney U test. RESULTS: We found PD in 17 (19%) and PA in 28 (32%) of participants. The likelihood of PD was increased if PA was also present (p = 0.008, phi = 0.28). Ten participants (11%) experienced overlapping PD and PA. Participants with PD (r = -0.38, p = 0.004), PA (r = -0.51, p < 0.000) or both (r = -0.52, p < 0.000) had poorer functioning at follow-up than participants without persisting symptoms. CONCLUSION: PD, PA and overlapping PD/PA is highly prevalent and associated with severely impaired functioning in FEP. Correct identification of these patients is a prerequisite for initiating relevant treatment early in the course of illness.

Self-rated disability in first treated episode of psychosis: A 1-year follow-up study.

OBJECTIVES: Knowledge about self-rated disability over time in psychotic disorders is limited. How self-rated disability relates to clinician-rated global functioning, self-rated life satisfaction and symptomatology was investigated across the first year of treatment in early psychosis. METHODS: Participants with first treated episode of psychosis (n = 115) were investigated at baseline and 1-year follow-up. Self-rated Disability was measured with World Health Organization- Disability Assessment Schedule 2.0. Clinician-rated global functioning, self-rated life satisfaction, and symptomatology were measured with appropriate scales. RESULTS: Average self-rated disability in first-treated episode of psychosis was high, corresponding with the 10% highest in a general population sample. However, 37% were not disabled at a clinically significant level after one year. Self-rated disability was highest in the two social domains (Getting along with people and Participation in society), but improved significantly from baseline to 1-year. At 1-year follow-up self-rated disability had significant weak to medium correlations with clinician-rated global functioning and positive symptoms, and mainly medium to strong correlations with life satisfaction and depressive symptoms. Yet only baseline depression significantly predicted disability after one year. CONCLUSION: Self-rated disability in first treated episode of psychosis is high, but improves across the first year, indicating signs of early recovery. Moreover, self-rated disability is related, but distinct from clinician-rated global functioning and self-rated life satisfaction, suggesting that self-rated disability should also be assessed in order to more fully describe outcomes in first episode psychosis. The findings highlight the need for specialised treatment of depression and social disability in early psychosis.

Depression and functioning are important to subjective quality of life after a first episode psychosis.

BACKGROUND: Subjective quality of life (S-QoL) is an important outcome measure in first-episode psychosis, but its associations with clinical predictors may vary across the illness course. In this study we examine the association pattern, including both direct and indirect effects, between specific predefined clinical predictors (insight, depression, positive psychotic symptoms and global functioning) and S-QoL the first ten years after a first-episode psychosis. METHODS: Three hundred and one patients with a first-episode psychosis were included at first treatment, and reassessed at 3 months, 1 year, 2 years, 5 years and 10 years after inclusion. At 10-year follow-up 186 participated. S-QoL was assessed with Lehman's Quality of Life Interview. Applying a structural equation model, we investigated cross-sectional association patterns at all assessments between the predefined clinical predictors and S-QoL. RESULTS: At baseline, only depression was significantly associated with S-QoL. At all follow-up assessments, depression and functioning showed significant associations with S-QoL. Insight was not associated with S-QoL at any of the assessments. Better insight, less depressive symptoms and less positive psychotic symptoms were all associated with higher functioning at all assessments. Functioning seems to mediate a smaller indirect inverse association between positive psychotic symptoms and S-QoL. The association pattern was stable across all follow-up assessments. CONCLUSIONS: Together with depression, functioning seems to be important for S-QoL. Functioning seems to be a mediating factor between positive symptoms and S-QoL. A focus on functional outcome continues to be important.

Extreme challenges: psychiatric inpatients with severe self-harming behavior in Norway: a national screening investigation.

BACKGROUND: Extreme self-harming behavior is a major challenge for patients and health services. Nevertheless, this patient population is poorly described in research literature. AIMS: The aim of this study was to assess the volume of patients with extensive psychiatric hospitalization due to extreme self-harming behaviors, the extent of severe medical sequelae, and collaboration problems within health services. METHODS: In a national screening investigation, department managers in 83 adult psychiatric inpatient institutions across all health regions in Norway were invited to participate in a brief, prepared, telephone interview. RESULTS: Sixty-one interviews were completed. Extensive hospitalization (prolonged or multiple) due to extreme self-harm was reported for the last year in all health regions and in 427 individual cases. Mean number of cases did not differ by region. Psychiatric hospitalizations were more frequent in hospital units than mental health centers. In 109 of the cases, self-harming behavior had severe medical consequences, including five deaths. In 122 of the cases, substantial collaboration problems within the health services were reported (disagreements on diagnosis, treatment needs and resources). Extensive (long-term) hospitalization was particularly associated with the combination of severe medical sequelae and collaboration problems. CONCLUSION: This investigation confirms a noteworthy, nationwide, population of severely self-harming inpatients with extensive health service use, prevalent severe medical complications, and unsatisfactory collaboration within health services. These preliminary results are alarming, and indicate a need for more profound understanding of highly complex and severe cases.

The impact of immigration and visible minority status on psychosis symptom profile.

PURPOSE: Immigrants have heightened risks of psychotic disorders, and it is proposed that migration influences symptom profiles. The purpose of this study was to investigate if either migration experience and/or visible minority status affected symptom profiles, using a cross-culturally validated five-factor model of the Positive and Negative Syndrome Scale (PANSS), in patients with broadly defined psychotic disorders. METHODS: PANSS was assessed in a large catchment area based sample of patients with psychotic disorders verified with the Structured Clinical Interview for DSM-IV (n = 1,081). Symptom profiles based on Wallwork et al. five-factor model were compared for Norwegians (73 %), white immigrants (10.5 %), and visible minority groups (16.5 %). RESULTS: Visible minorities were significantly younger, had less education, more often a schizophrenia diagnosis and higher PANSS positive, negative and disorganized/concrete factor scores than Norwegians and white immigrants. After controlling for confounders only the items "Delusions" and "Difficulty in abstract thinking" differed between groups. Multivariate analyses indicated that these items were not associated with immigration per se, but rather belonging to a visible minority. CONCLUSION: We found mostly similarities in psychotic symptoms between immigrants and Norwegians when using a cross-culturally validated five-factor model of the PANSS. Immigration did not directly influence psychotic symptom profiles but visible minority groups had higher levels of "Delusions" and "Difficulty in abstract thinking", both symptoms that are partially context dependent.

Childhood trauma and treatment resistance in first-episode psychosis: Investigating the role of premorbid adjustment and duration of untreated psychosis.

BACKGROUND: Early identification of treatment non-response in first-episode psychosis (FEP) is essential to outcome. Despite indications that exposure to childhood trauma (CT) can have adverse effects on illness severity, its impact on treatment non-response and the interplay with other pre-treatment characteristics is sparsely investigated. We use a lack of clinical recovery as an early indicator of treatment resistance to investigate the relationship between CT and treatment resistance status at one-year follow-up and the potential mediation of this effect by other pre-treatment characteristics. METHODS: This prospective one-year follow-up study involved 141 participants recruited in their first year of treatment for a schizophrenia-spectrum disorder. We investigated clinical status, childhood trauma (CT), premorbid adjustment (PA), and duration of untreated psychosis (DUP) at baseline and clinical status at one-year follow-up. Ordinal regression analyses were conducted to investigate how PA and DUP affected the relationship between CT and one-year outcome in FEP. RESULTS: 45 % of the FEP sample reported moderate to severe CT, with significantly higher levels of CT in the early treatment resistant group compared to participants with full or partial early recovery. Ordinal regression analysis showed that CT was a significant predictor of being in a more severe outcome group (OR = 4.59). There was a partial mediation effect of PA and a full mediation effect of DUP on the effect of CT on outcome group membership. DISCUSSION: Our findings indicate that reducing treatment delays may mitigate the adverse effects of CT on clinical outcomes and support the inclusion of broad trauma assessment in FEP services.

Depressive symptoms in first episode psychosis: a one-year follow-up study.

BACKGROUND: Depressive symptoms are common in patients with first episode psychosis (FEP) and have serious consequences for them. The main aims of this study were to examine the course of depression in FEP patients and explore whether any patient characteristics at baseline predicts depressive symptoms after one year. METHOD: A total of 198 FEP patients with schizophrenia spectrum disorders were assessed for depressive symptoms with Calgary Depression Scale for Schizophrenia (CDSS) at baseline and 127 were followed for one year. A CDSS score [greater than or equal to] 6 was used as a cut-off score for depression. RESULTS: Approximately 50% of the patients were depressed (CDSS[greater than or equal to]6) at baseline. At follow-up approximately 35% had depression. The course of depressive symptoms varied, 26% was depressed at both baseline and follow-up, 9% became depressed during the follow-up, 22% remitted from depression during the 12 months and 43% was neither depressed at baseline nor at follow-up. Poor childhood social functioning, long duration of untreated psychosis (DUP) and depressive symptoms at baseline predicted depression at 12 months follow-up. CONCLUSION: Depressive symptoms are frequent in the first year after onset of psychosis. Patients with poor social functioning in childhood, long DUP and depressive symptoms at baseline are more prone to have depressive symptoms after one year. These patients should be identified and proper treatment provided.

Object relations, reality testing, and social withdrawal in schizophrenia and bipolar disorder.

In this study, we investigated the relationships between observed social withdrawal (Positive and Negative Syndrome Scale [PANSS] Passive Social Withdrawal and PANSS Active Social Avoidance), subjectively experienced social withdrawal (Social Functioning Scale [SFS] Withdrawal and SFS Interpersonal Behavior), and their associations to the underlying psychological patterns of Object Relations and Reality Testing. Patients with schizophrenia (n = 55) and bipolar disorder (n = 51) from the ongoing Thematically Organized Psychosis project, Oslo University Hospital, Norway, were evaluated using the Bell Object Relations and Reality Testing Inventory, the PANSS, and the SFS. Object relations and reality testing subscales related differentially to PANSS Passive Social Withdrawal and PANSS Active Social Avoidance. These two measures, together with the level of alienation, explained a significant amount of variance in self-experienced social dysfunction. Findings reveal the multidimensional nature of social dysfunction in severe mental disorders.

Creative writing as a means to recover from early psychosis- Experiences from a group intervention.

BACKGROUND: In this paper, we explore the subjective experiences of a group intervention in creative writing (CW) for young adults being treated for psychosis. METHOD: A qualitative and exploratory design was applied. Five out of eight patients who were offered a course in CW with two-hour weekly sessions for 12 weeks took part in this study. The five participants who followed through were interviewed after project termination. Systematic text condensation was applied to the transcribed interviews. RESULTS: The analysis revealed three overarching themes: a) the group was valued as a creative community, b) there was safety in the structured yet flexible framing of the course, c) the participants experienced creative freedom that enabled a feeling of mastery. CONCLUSION: CW was well conceived. The feelings of connectedness and mastery were prominent. The participants experienced growth on several levels. Our findings support previous work on arts therapy as a means to recovery.

Crossing boundaries in the delivery of healthcare - a qualitative study of an eHealth intervention in relation to boundary object theory.

With the increasing trend of digitalisation in the health sector, eHealth is being deployed to facilitate interaction between health professionals and service users without physical contact or close proximity. It became prominent during the COVID-19 era when mobility for physical meetings was restricted. Focusing on a video-supported digital toolkit, REACT-NOR, this study explored the experiences of caregivers and supporters in relation to the notion of boundary object. In-depth semi-structured interviews were conducted with 10 supporters and 11 caregivers to gather first-hand experience on the use of the digital tool. It emerged from the study that the use of REACT-NOR made a huge difference for the involved parties by bridging the knowledge gap between supporters and caregivers. The use of the video in particular was useful in engaging and emotionally connecting the supporters and caregivers, resulting in an exciting digital experience. The effectiveness of the digital tool can be explained in the context of a boundary object in that it facilitated the processes of transferring, translating and transforming knowledge. The tool exhibited the attributes of dynamism, flexibility, standardisation and shared structure, which resonates with the notion of a boundary object. An understanding of how boundary objects work is crucial especially with remote care, as depicted in this study, due to the fact that the transfer of knowledge involves multiple processes such as sharing of new and existing knowledge, translation to make it accessible to others and transformation to render it usable across different boundaries.
