Abstract

Aims.

Compulsory admission can be experienced as devaluing and stigmatising by people with mental illness. Emotional reactions to involuntary hospitalisation and stigma-related stress may affect recovery, but longitudinal data are lacking. We, therefore, examined the impact of stigma-related emotional reactions and stigma stress on recovery over a 2-year period.

Method.

Shame and self-contempt as emotional reactions to involuntary hospitalisation, stigma stress, self-stigma and empowerment, as well as recovery were assessed among 186 individuals with serious mental illness and a history of recent involuntary hospitalisation.

Results.

More shame, self-contempt and stigma stress at baseline were correlated with increased self-stigma and reduced empowerment after 1 year. More stigma stress at baseline was associated with poor recovery after 2 years. In a longitudinal path analysis more stigma stress at baseline predicted poorer recovery after 2 years, mediated by decreased empowerment after 1 year, controlling for age, gender, symptoms and recovery at baseline.

Conclusion.

Stigma stress may have a lasting detrimental effect on recovery among people with mental illness and a history of involuntary hospitalisation. Anti-stigma interventions that reduce stigma stress and programs that enhance empowerment could improve recovery. Future research should test the effect of such interventions on recovery.

Introduction

Involuntary admissions to psychiatric hospitals are common but may have pernicious consequences for people with mental illness. Stigma refers to labelling, stereotyping, separation, status loss and discrimination that occur in a situation that gives relatively less power to the stigmatised (Link & Phelan, Reference Link and Phelan2001). This conceptualisation explains why compulsory hospitalisation may increase the likelihood that people with mental illness feel devalued and stigmatised, as compulsory admission involves the exercise of power in treating labelled individuals and may constitute a loss of social status (Link et al. Reference Link, Castille and Stuber2008; Livingston & Rossiter, Reference Livingston and Rossiter2011). Involuntarily admitted individuals may feel shame and be embarrassed as a reaction to having deviated from cultural or social norms (Gilbert & Andrews, Reference Gilbert, Andrews, Gilbert and Andrews1998; Svindseth et al. Reference Svindseth, Nottestad and Dahl2013). On the other hand, failure to meet one's own expectations may result in self-contempt (Green et al. Reference Green, Moll, Deakin, Hulleman and Zahn2013; Zahn et al. Reference Zahn, Lythe, Gethin, Green, Deakin, Young and Moll2015). It has been proposed that individuals are more likely to devalue themselves if they feel no control over their treatment and feel incapable of functioning independently (Katsakou & Priebe, Reference Katsakou and Priebe2007). These stigma-related emotional reactions to involuntary hospitalisation can be stressful even after discharge (Katsakou et al. Reference Katsakou, Rose, Amos, Bowers, McCabe, Oliver, Wykes and Priebe2012; Rüsch et al. Reference Rüsch, Müller, Lay, Corrigan, Zahn, Schönenberger, Bleiker, Lengler, Blank and Rössler2014b). According to stress-coping models of stigma (Lazarus & Folkman, Reference Lazarus and Folkman1984; Major & O'Brien, Reference Major and O'Brien2005), however, people with mental illness are not passive recipients of stigma and its negative consequences. Stigma-related stress occurs when individuals perceive a stigma-related threat that exceeds their perceived coping resources. Thus, stigma stress involves the primary cognitive appraisal of the harm resulting from stigma and the secondary appraisal of the resources the individual has to cope with that harm (Rüsch et al. Reference Rüsch, Corrigan, Wassel, Michaels, Olschewski, Wilkniss and Batia2009a, Reference Rüsch, Corrigan, Powell, Rajah, Olschewski, Wilkniss and Batiab).

Self-stigma describes the cognitive process of agreeing with and internalising negative stereotypes (‘Because I have a mental illness, I am worthless and can never get better’). It is associated with the emotions of shame (Rüsch et al. Reference Rüsch, Hölzer, Hermann, Schramm, Jacob, Bohus, Lieb and Corrigan2006) and self-contempt, described by stigma theorists (Goffman, Reference Goffman1963) and people with lived experience of mental illness (Lipfird, Reference Lipfird2015) as a barrier to recovery. Personal empowerment represents a sense of power, control, activism and optimism, which is often conceptualised as the opposite of self-stigma. The potential for self-stigma and impaired empowerment to influence recovery is consistent with the ‘why try’ effect (Corrigan et al. Reference Corrigan, Larson and Rüsch2009), which suggests that people who internalise negative stereotypes of mental illness may suffer reduced self-worth and believe they are unworthy or incapable of achieving life goals, resulting in poor recovery.

A review of qualitative studies concluded that compulsory treatment can lead to loss of power, low self-esteem and feelings of hopelessness (Katsakou & Priebe, Reference Katsakou and Priebe2007). In a longitudinal quantitative study, perceived coercion had detrimental effects on perceived stigma, decreased self-esteem and poor quality of life (Link et al. Reference Link, Castille and Stuber2008). A cross-sectional study (Rüsch et al. Reference Rüsch, Müller, Lay, Corrigan, Zahn, Schönenberger, Bleiker, Lengler, Blank and Rössler2014b) of our sample at baseline found that stigma stress, shame and self-contempt were associated with more self-stigma and impaired empowerment which were related to poor self-esteem and quality of life. A small longitudinal study of individuals with mental illness who received compulsory community treatment reported that self-stigma at baseline was negatively correlated with baseline quality of life, however, self-stigma did not predict the quality of life after 1 year (Livingston et al. Reference Livingston, Rossiter and Verdun-Jones2011).

Recovery from mental illness involves not only returning to the pre-illness level of functioning but also regaining self-determination and the development of a meaningful life (Andresen et al. Reference Andresen, Caputi and Oades2010; Silverstein et al. Reference Silverstein and Bellack2008). For involuntarily admitted individuals, the path to recovery includes developing a positive sense of identity, building self-esteem as well as taking back control over their treatment and lives (Slade et al. Reference Slade, Amering, Farkas, Hamilton, O'Hagan, Panther, Perkins, Shepherd, Tse and Whitley2014). It is of particular value to understand how stigma-related emotional and cognitive responses to involuntary hospitalisation affect recovery in this population. Building on the previous findings (Link et al. Reference Link, Castille and Stuber2008; Livingston et al. Reference Livingston, Rossiter and Verdun-Jones2011; Rüsch et al. Reference Rüsch, Müller, Lay, Corrigan, Zahn, Schönenberger, Bleiker, Lengler, Blank and Rössler2014b), we developed a path model in which shame, self-contempt and stigma stress would predict self-stigma and empowerment, which further predict recovery over a 2-year period.

The current study aimed to test the hypotheses that (i) higher levels of shame and self-contempt in reaction to involuntary hospitalisation as well as more stigma stress at baseline would predict poor recovery after 2 years; and (ii) increased self-stigma and decreased empowerment after 1 year would mediate this relationship, controlling for age, gender, symptoms and baseline recovery.

Methods

Participants

This study is part of a randomised-controlled trial (RCT) of an intervention including psychoeducation, crisis cards and preventive monitoring to reduce compulsory psychiatric admissions among people with serious mental illness in the Canton of Zürich, Switzerland. Consecutive users of inpatient mental health care in four psychiatric hospitals in the Canton of Zürich, Switzerland, were invited to participate in the project. Participants fulfilled the following inclusion criteria: (a) at least one involuntary psychiatric hospitalisation in the past 24 months, (b) aged between 18 and 65 years, (c) living in the Canton of Zürich, Switzerland, and (d) ability to provide written informed consent. Exclusion criteria were an organic mental disorder, mental retardation or insufficient German language skills. Participants were recruited between April 2010 and July 2012. Eligible inpatients were randomised to the intervention or treatment as usual. Details of study design, sample characteristics and recruitment are described elsewhere (Lay et al. Reference Lay, Salize, Dressing, Rüsch, Schönenberger, Bühlmann, Bleiker, Lengler, Korinth and Rössler2012).

We defined completers as participants who provided data at baseline as well as 1- or 2-year follow-up. Data for our analyses were available from 186 participants at baseline, 152 (82%) at 1-year and 141 (76%) at 2-year follow-up. The main reasons for dropout were participants not being contactable, providing incomplete data or deciding to discontinue the study (Lay et al. Reference Lay, Salize, Dressing, Rüsch, Schönenberger, Bühlmann, Bleiker, Lengler, Korinth and Rössler2012). ICD-10 psychiatric diagnoses were recorded for each participant from medical records. The most common psychiatric diagnoses were affective disorders (n = 80, 43%) and psychotic disorders (n = 50, 27%). In the whole sample, 57 (31%) had a comorbid substance-related disorder. The average duration of mental illness was 16 years (SD = 12.5, range 0.5–49 years).

Measures

Emotional reactions to involuntary hospitalisation were assessed by one item on shame (‘I felt shame to receive involuntary psychiatric treatment’) and one item on self-contempt (‘I felt self-contempt to receive involuntary psychiatric treatment’), both rated from 1 (not at all) to 9 (extreme) (Rüsch et al. Reference Rüsch, Müller, Lay, Corrigan, Zahn, Schönenberger, Bleiker, Lengler, Blank and Rössler2014b).

Stigma stress was assessed by the 8-item Stigma Stress Scale (Rüsch et al. Reference Rüsch, Corrigan, Wassel, Michaels, Olschewski, Wilkniss and Batia2009a, Reference Rüsch, Corrigan, Powell, Rajah, Olschewski, Wilkniss and Batiab), which includes two 4-item subscales, one on the primary appraisal of mental illness stigma as harmful (e.g. ‘Prejudice against people with mental illness will have harmful or bad consequences for me’; Cronbach's alpha = 0.95 at baseline) and the other on the secondary appraisal of perceived coping resources (e.g. ‘I have the resources I need to handle problems posed by prejudice against people with mental illness’; Cronbach's alpha = 0.86 at baseline). Items were scored from 1 to 7 with higher scores representing higher agreement. Stigma stress was computed by subtracting perceived coping resources from perceived harmfulness, higher difference scores from −6 to +6 indicating more stigma stress.

Self-stigma was measured by the 29-item Internalized Stigma of Mental Illness Inventory (ISMI, Ritsher et al. Reference Ritsher, Otilingam and Grajales2003). The ISMI is designed to assess internalised and subjective experience of stigma, which comprises five subscales: alienation, stereotype endorsement, discrimination experience, social withdrawal and stigma resistance. Since the 5-item stigma resistance subscale had low internal consistency in our sample (Cronbach's alpha = 0.54 at baseline and at 1-year follow-up), it was not included in the total score. A mean score from 1 to 4 in the remaining 24 items was calculated. Higher scores indicate more self-stigma. The 28-item Empowerment Scale (Rogers et al. Reference Rogers, Chamberlin, Ellison and Crean1997) was used to assess the personal sense of empowerment with higher mean scores from 1 to 4 equaling greater empowerment (baseline/1-year follow-up: Cronbach's alpha = 0.84/0.80).

Self-esteem was assessed using the 10-item Rosenberg Self-Esteem Scale (Rosenberg, Reference Rosenberg1965) with a mean score between 0 and 3 (Baseline/2-year follow-up: Cronbach's alpha = 0.88/0.89). Overall functioning was assessed by the Global Assessment of Functioning (American Psychiatric Association, 2000) from 1 to 100. Self-esteem and functioning were positively correlated (r = 0.45, p < 0.001, at 2-year follow-up). Z-standardised scores of self-esteem and functioning were calculated and then averaged into one recovery score, by transforming the mean scores of the two scales into percentile scores. At baseline, all measures were administered. Data on self-stigma and empowerment were collected again at 1-year follow-up, recovery again at 2-year follow-up. Symptoms were assessed by the 24-item Brief Psychiatric Rating Scale (Lukoff et al. Reference Lukoff, Liberman and Nuechterlein1986) yielding sum scores at baseline, 1-year and 2-year follow-up.

Statistical analyses

Data were analysed using SPSS 21 and MPlus 7.4 (Muthén & Muthén, Reference Muthén and Muthén1998–2002). Independent t-test or Chi-square tests were used to compare baseline sociodemographic and clinical variables between completers and non-completers at 1- and 2-year follow-up. We used Pearson's correlations to analyse the associations between predictors (shame and self-contempt in reaction to involuntary hospitalisation and stigma stress, all at baseline), mediators (self-stigma and empowerment at 1-year follow-up) and outcome (recovery after 2 years).

The hypothesised model was then tested in a path analysis using Mplus and Maximum Likelihood estimation, controlling for age, gender, intervention status (intervention vs. control), symptoms and baseline levels of self-stigma, empowerment and recovery. In the path analysis, we examined whether stigma stress, shame and self-contempt in reaction to involuntary hospitalisation at baseline directly predicted recovery after 2 years. Additionally, the model tested mediation effects of self-stigma and empowerment at 1-year follow-up on the association between stigma stress, shame and self-contempt in reaction to involuntary hospitalisation at baseline and recovery after 2 years. The model is considered to fit the data well when χ2/df < 2, CFI > 0.90, TLI > 0.90, RMSEA < 0.08, SRMR < 0.08 (Kenny, Reference Kenny2015). Standardised coefficients and 95% confidence intervals were based on 5000 bootstrapped standard errors.

We first tested the hypothesised model in Mplus and missing values were handled using Full Information Maximum Likelihood (FIML, Muthén & Muthén Reference Muthén and Muthén1998–2002). Since FIML does not handle missing values of covariates, we then used multiple imputations by Fully Conditional Specification as implemented in SPSS to impute missing values (White et al. Reference White, Royston and Wood2011). Imputed data were based on observed values of all variables in the model including the covariate and outcome variables. The number of imputations was set to 5. The hypothesised model was then tested in the imputed data.

Results

Baseline characteristics of completers and non-completers

The 34 individuals who did not participate in the 1-year follow-up assessment did not differ significantly from the 152 participants who completed it in terms of baseline sociodemographic or clinical characteristics, except for completers being older than non-completers (M = 44.3 vs. M = 38.0; t = 2.9, p = 0.004) and a higher dropout rate in the intervention group (65% vs. 44%; χ2 = 4.7, p = 0.03). One difference in baseline characteristics between completers and non-completers at 2-year follow-up was observed, namely completers being older than non-completers (M = 44.5 vs. M = 38.9; t = 2.8, p = 0.005; Table 1).

Bivariate correlations between predictors, mediators and outcome variables

Higher levels of stigma stress, shame and self-contempt at baseline were associated with more self-stigma (r = 0.49, p < 0.001; r = 0.24, p = 0.005; r = 0.28, p = 0.001, respectively) and less empowerment after 1 year (r = −0.34, p < 0.001; r = −0.22, p = 0.009; r = −0.26, p = 0.002, respectively). At 1-year follow-up, self-stigma and empowerment were significantly negatively correlated (r = −0.65, p < 0.001). More stigma stress at baseline was associated with poorer recovery after 2 years (r = −0.27, p = 0.003), whereas shame and self-contempt at baseline were unrelated to recovery at 2-year follow-up (r = −0.14, p = 0.12; r = −0.11, p = 0.22, respectively). More self-stigma and less empowerment after 1 year were related to poor recovery after 2 years (r = −0.47, p < 0.001; r = −0.50, p < 0.001, respectively). A higher level of symptoms at baseline was associated with more self-stigma (r = 0.28, p = 0.001) and less empowerment after 1 year (r = −0.20, p = 0.02). The number of involuntary hospitalisations in the 24 months before baseline was not correlated with stigma stress (r = 0.03, p = 0.66), shame (r = 0.04, p = 0.63) and self-contempt (r = 0.02, p = 0.83) at baseline, with self-stigma (r = 0.14, p = 0.11) and empowerment (r = 0.007, p = 0.94) at 1-year follow-up, or with recovery (r = −0.05, p = 0.60) after 2 years (Table 2).

Path analysis of the hypothesised model

The path analysis based on non-imputed data indicated good model fit (χ2 = 17.67, df = 15, p = 0.28, χ2/df = 1.18, RMSEA = 0.037, CFI = 0.988, TLI = 0.971, SRMR = 0.030, Fig. 1). In this path model, shame and self-contempt at baseline had no significant direct or indirect effect on recovery at 2-year follow-up. There was a trend-level negative association between shame at baseline and empowerment after 1 year. Stigma stress at baseline had a significant effect on self-stigma and empowerment after 1 year. Empowerment at 1-year follow-up was significantly associated with recovery after 2 years. Stigma stress at baseline and recovery after 2 years were significantly associated in a bivariate correlation (r = −0.27, p = 0.003); in the full model, this association was not significant r = 0.02, p = 0.82), suggesting full mediation. Decreased empowerment after 1 year fully mediated the link between baseline stigma stress and recovery after 2 years (β = −0.05, 95% CI −0.13 to −0.003). More than half of recovery's variance was explained by the model (R 2 = 0.57).

For results of the same model with imputed data (n = 186) see Online Figure 1. *p < 0.05, **p < 0.01, ***p < 0.001, +p = 0.08.

To account for a potential bias due to dropouts and missing data after 1 and 2 years, we repeated the path analysis following multiple imputations of missing data. The model fit of the path model in the imputed data was good (χ2 = 27.19, df = 15, p = 0.20, χ2/df = 1.82, RMSEA = 0.054, CFI = 0.971, TLI = 0.930, SRMR = 0.029, Online Fig. S1). The results based on imputed data were almost identical to those based on non-imputed data.

Discussion

Our findings suggest that increased stigma stress had a long-term negative effect on recovery, mediated by decreased empowerment and independent of age, gender, symptom levels and baseline recovery. Consistent with previous findings (Rüsch et al. Reference Rüsch, Müller, Lay, Corrigan, Zahn, Schönenberger, Bleiker, Lengler, Blank and Rössler2014b), shame, self-contempt and stigma stress were correlated with increased self-stigma and decreased empowerment after 1 year. There was no significant correlation between the number of recent involuntary hospitalisations before baseline and self-stigma, empowerment or recovery, which indicates that the emotional and cognitive perceptions of coercion, rather than the coercive experiences per se, may determine the negative impact of involuntary hospitalisation. In the path analysis, stigma stress, or the perception of stigmatised individuals that they do not have sufficient resources to cope with stigma-related harm, is a more important determinant of self-stigma and impaired empowerment than shame and self-contempt, which is consistent with stress-coping models of mental illness stigma (Lazarus & Folkman, Reference Lazarus and Folkman1984; Rüsch et al. Reference Rüsch, Corrigan, Wassel, Michaels, Olschewski, Wilkniss and Batia2009a, Reference Rüsch, Corrigan, Powell, Rajah, Olschewski, Wilkniss and Batiab).

The findings further confirm the concept of self-stigma and empowerment as opposite poles of a continuum (Rüsch et al. Reference Rüsch, Müller, Lay, Corrigan, Zahn, Schönenberger, Bleiker, Lengler, Blank and Rössler2014b). At the negative end of the continuum are people who internalise negative stereotypes of mental illness and have low self-esteem and self-efficacy. At the positive end are people who have a sense of power and are confident about the pursuit of their goals (Corrigan et al. Reference Corrigan, Larson and Rüsch2009). Our findings are also in line with studies that highlight the role of empowerment for recovery from serious mental illness (Leamy et al. Reference Leamy, Bird, Le Boutillier, Williams and Slade2011). Empowering people with mental illness should be an important goal of interventions to achieve gains in social functioning and self-concept because socialisation and a functional sense of self-appear to be important factors involved in recovery (Silverstein et al. Reference Silverstein and Bellack2008). For example, individuals who have the confidence they can cope with stigma and its harmful consequences in the social context may have a sense of control and mastery that supports their recovery.

Although stigma stress in our study did not specifically refer to the stigma associated with involuntary hospitalisation, in a large international survey individuals with schizophrenia suffered from more experienced discrimination and thus were more likely to be distressed by it if they had experienced involuntary treatment (Thornicroft et al. Reference Thornicroft, Brohan, Rose, Sartorius and Leese2009). Future research should include participants with and without a history of compulsory admission to examine whether our findings are specific for people with experience of involuntary treatment. That said, recent findings suggest that stigma stress negatively affects even individuals with subthreshold syndromes in the community (Schibalski et al. Reference Schibalski, Müller, Ajdacic-Gross, Vetter, Rodgers, Oexle, Corrigan, Rössler and Rüsch2017). Future studies should also compare the role of mental health service systems and different compulsory admission rates for stigma's impact on recovery.

To the best of our knowledge, this is the first longitudinal study on stigma-related cognitive as well as emotional reactions to involuntary hospitalisation. Data collected at baseline, 1- and 2-year follow-up allow testing possible causal relationships between stigma-related variables and recovery in path analysis. We also adjusted for several potential confounding variables in the path analysis. The findings add to our knowledge about long-term effects of stigma on recovery among people with severe mental illness.

This study has some limitations. Almost one-fourth of participants had dropped out after 2 years and non-completers were younger than completers. The results based on imputed data were almost identical to those with non-imputed data, suggesting that dropout did not bias our findings. Recovery was not assessed by a comprehensive measure of personal recovery; instead, it was operationalised as the average of self-reported self-esteem and clinician-rated functioning, reflecting key domains of clinical and personal recovery. Other domains such as hope and optimism were not included and should be examined in future studies. Last not least, a longitudinal path analysis does not prove causality.

Despite these limitations, our findings have implications for efforts to reduce stigma's impact and to support recovery. In this study, randomisation to the intervention condition, which included psychoeducation, crisis cards and preventive monitoring, was controlled for in path analyses. It was not associated with improvement in self-stigma, empowerment or recovery, which underlines that additional and targeted interventions may be needed to reduce the negative impact of involuntary hospitalisation in the long-term. Given the path from stigma stress via disempowerment to poor recovery, there are two promising targets for interventions. Firstly, besides different interventions to reduce self-stigma among people with mental illness (Mittal et al. Reference Mittal, Sullivan, Chekuri, Allee and Corrigan2012; Tsang et al. Reference Tsang, Ching, Tang, Lam, Law and Wan2016), the peer-led Honest, Open, Proud group program (HOP, formerly known as Coming Out Proud) empowers individuals to make decisions, whether or not to disclose their mental illness in different settings. In three RCTs (Rüsch et al. Reference Rüsch, Abbruzzese, Hagedorn, Hartenhauer, Kaufmann, Curschellas, Ventling, Zuaboni, Bridler, Olschewski, Kawohl, Rössler, Kleim and Corrigan2014a; Corrigan et al. Reference Corrigan, Larson, Michaels, Buchholz, Del Rossi, Fontecchio, Castro, Gause, Krzyzanowski and Rüsch2015; Mulfinger et al. Reference Mulfinger, Müller, Böge, Sakar, Corrigan, Evans-Lacko, Nehf, Djamali, Samarelli, Kempter, Ruckes, Libal, Oexle, Noterdaeme and Rüsch2018) HOP significantly reduced stigma stress. The acquired decision-making skills might be continually used by participants after the intervention, which could improve resilience to stigma and reduce stigma-related stress. Based on our path model, we could speculate that HOP, by reducing stigma stress as a proximal outcome, might support long-term recovery as a distal outcome. Secondly, interventions that directly promote empowerment, such as advance directives or joint crisis plans, may foster recovery. As a recovery-oriented intervention, advance directives could empower individuals through the enhancement of insight, self-esteem, control over and satisfaction with treatment (Khazaal et al. Reference Khazaal, Manghi, Delahaye, Machado, Penzenstadler and Molodynski2014). Joint crisis plans support the empowerment process while facilitating early detection and relapse prevention (Henderson et al. Reference Henderson, Farrelly, Moran, Borschmann, Thornicroft and Birchwood2015).

Future studies should examine whether recovery can be improved by interventions that address public stigma among key groups such as healthcare providers or police; that reduce compulsion rates and their negative effects in healthcare systems (de Jong et al. Reference de Jong, Kamperman, Oorschot, Priebe, Bramer, van de Sande, Van Gool and Mulder2016); and that support individuals with mental illness in their struggle with self-stigma and stigma stress and in their effort to gain empowerment.
