Reliability and validity of the Danish version of the Schema Mode Inventory (SMI)

Schema therapy versus treatment as usual for outpatients with difficult-to-treat depression: study protocol for a parallel group randomized clinical trial (DEPRE-ST)

BACKGROUND

About one third of patients with depression are in a condition that can be termed as "difficult-to-treat". Some evidence suggests that difficult-to-treat depression is associated with a higher frequency of childhood trauma and comorbid personality disorders or accentuated features. However, the condition is understudied, and the effects of psychotherapy for difficult-to-treat depression are currently uncertain. The aim of this trial is to investigate the beneficial and harmful effects of 30 sessions of individual schema therapy versus treatment as usual for difficult-to-treat depression in the Danish secondary, public mental health sector.

METHODS

In this randomized, multi-centre, parallel-group, superiority clinical trial, 129 outpatients with difficult-to-treat depression will be randomized (1:1) to 30 sessions of individual schema therapy or treatment as usual; in this context mainly group-based, short-term cognitive behaviour or psychodynamic therapy. The primary outcome is the change from baseline in depressive symptoms 12 months after randomization, measured on the observer-rated 6-item Hamilton Rating Scale for Depression. The secondary outcomes are health-related quality of life assessed with the European Quality of Life 5 Dimensions 5 Level Version, functional impairment assessed with the Work and Social Adjustment Scale, psychological wellbeing assessed with the WHO-5 Well-being Index, and negative effects of treatment assessed with the Negative Effects Questionnaire. Exploratory outcomes are improvement on patient self-defined outcomes, personal recovery, anxiety symptoms, anger reactions, metacognitive beliefs about anger, and perseverative negative thinking. Outcomes will be assessed at 6, 12, and 24 months after randomization; the 12-month time-point being the primary time-point of interest. Outcome assessors performing the depression-rating, data managers, statisticians, the data safety and monitoring committee, and conclusion makers for the outcome article will be blinded to treatment allocation and results. To assess cost-effectiveness of the intervention, a health economic analysis will be performed.

DISCUSSION

This trial will provide evidence on the beneficial and harmful effects, as well as the cost-effectiveness of schema therapy versus treatment as usual for outpatients with difficult-to-treat depression. The results can potentially improve treatment for a large and understudied patient group.

The Reliability and Validity of the Polish Version of the Schema Mode Inventory (SMI)

(1) Background: Schema therapy and working with schema modes is increasingly popular. Since there is no validated tool to measure schema modes in Poland, in this study, we present an assessment of the psychometric properties of the Polish version the Short Schema Mode Inventory (SMI) adaptation. (2) Methods: First, the original version of the scale was translated. Subsequently, a validity and reliability study was conducted on a sample of 240 patients and 400 non-patients. In particular, the factor structure of the inventory was checked, internal reliability and intercorrelations between subscales were tested, differences between the clinical and non-clinical groups in terms of the severity of each factor were examined, and construct validity was assessed by comparing the association of results with external variables. (3) Results: The results did not conclusively confirm the 14-factor structure postulated in the original scale. Nevertheless, the relatively best fit indices were obtained for such a model. The internal reliability for the 14 subscales ranged from 0.74 to 0.95 (McDonald's omega). Correlations between subscales demonstrated values from 0.03 to 0.72. The existence of differences between the clinical and non-clinical groups and the construct validity were confirmed. (4) Conclusions: The psychometric evaluation performed is mostly similar to the results obtained for other adaptations, and the results justify the inventory being used for research and clinical purposes when knowledge of its limitations is included.

A trait emotional intelligence perspective on schema modes

Schema modes (or modes) are a key concept in the theory underlying schema therapy. Modes have rarely been related to established models of personality traits. The present study thus investigates the associations between trait emotional intelligence (TEI) and 14 modes, and tests a global TEI-mode factors-general psychological distress mediation model. The study draws on self-report data from 173 inpatients from a German clinic for psychosomatic medicine. Global TEI correlated positively with both healthy modes (happy child and healthy adult) and negatively with 10 maladaptive modes. When modes were regressed on the four TEI factors, six (emotionality), five (well-being), four (sociability), and four (self-control) significant partial effects on 10 modes emerged. In the parallel mediation model, the mode factors internalization and compulsivity fully mediated the global TEI-general psychological distress link. Implications of the results for the integration of modes with traits in general and with TEI in particular as well as implications of low TEI as a transdiagnostic feature of personality malfunctioning are discussed.

The Higher-Order Structure of Schema Modes

In schema therapy, modes are proposed as a key concept and main target for treatment of personality disorders. The present study aimed to assess a comprehensive set of 20 modes, to explore their higher-order structure, and to link the mode factors to the generic schema factor and basic personality traits. The sample consisted of N = 533 inpatients. Earlier versions of the Schema Mode Inventory (SMI, SMI-2) were merged into the German Extended SMI (GE-SMI). Item-level confirmatory factor analyses indicated that the structure of 16 out of 20 GE-SMI scales might be unidimensional. Scale-level exploratory factor analysis revealed three hierarchically structured mode factors: internalization, externalization, and compulsivity. Regressing mode factor scores on the Big Five factors and the generic schema factor supported the validity of the mode factors. The hierarchical structure of modes will be linked to the Hierarchical Taxonomy of Psychopathology, and implications for case conceptualization and treatment will be discussed.

Patient-Reported ICD-11 Personality Disorder Severity and DSM-5 Level of Personality Functioning

This study evaluated the Standardized Assessment of Severity of Personality Disorder (SASPD) proposed for ICD-11 and the Level of Personality Functioning Scale-Brief Form 2.0 (LPFS-BF) developed for DSM-5 Section III and their relationships with external correlates. We used a clinical sample (N = 150; 33% women) of 65 psychiatric outpatients and 85 incarcerated addicts, who self-reported the SASPD and the LPFS-BF. We conducted correlation and regression analyses in order to determine the relative associations of these two measures with relevant external criteria. SASPD predominantly captured externalizing and other-related problems (e.g., potential harm to others), whereas LPFS-BF predominantly captured internalizing and self-related problems (e.g., identity and distress). Generally, LPFS-BF explained more variance of the external criteria relative to SASPD. The findings seem to reflect that the ICD-11 oriented SASPD emphasizes interpersonal and aggressive features, whereas the DSM-5-oriented LPFS-BF emphasizes self-pathology and distress. More conclusive findings warrant interview-rated personality functioning.

Turkish adaptation of the Short Schema Mode Inventory

The purpose of the current study is to present the psychometric properties of the Short Schema Mode Inventory in the Turkish culture. The study sample comprised 1,287 participants, including both clinical and nonclinical participants. The age of the participants ranged between 18 and 48 years. The construct validity of the scale was tested using confirmatory factor analysis. The internal (Cronbach's alpha) and test-retest reliability coefficients were used to examine the reliability of the scale. Discriminant validity was investigated by comparing the nonclinical and clinical participants. Concurrent validity was tested via the Splitting Scale. The results of the study showed that the tested model had good data-model fit statistics. Additionally, the reliability analyses revealed that the scales had good internal and test-retest reliability coefficients. A significant association was found between the subscales of the Schema Mode Inventory. Furthermore, the scores of the clinical participants were significantly higher compared with the scores of the nonclinical participants for the maladaptive schema modes. Nonetheless, the participants in the nonclinical group had significantly higher levels of the healthy schema modes than individuals in the clinical group. The results of this study demonstrated that the Schema Mode Inventory was a reliable and valid instrument to measure schema modes in the Turkish population.

Schema therapy conceptualization of personality functioning and traits in ICD-11 and DSM-5

PURPOSE OF REVIEW

Schema therapy conceptualizes personality disorders in terms of modes and underlying schemas. This article reviews the literature on schema therapy conceptualization of personality disorder functioning and traits, and proposes how these findings apply to novel personality disorder classification in ICD-11 and the DSM-5 Alternative Model of Personality Disorders (AMPD).

RECENT FINDINGS

Maladaptive schemas and modes are generally associated with personality dysfunction and traits in conceptually coherent ways. The healthy adult mode, a transdiagnostic core concept in schema therapy, corresponds to the ICD-11 and DSM-5-AMPD features of core personality functioning. Modes and underlying schemas substantially overlap with specific ICD-11 and DSM-5-AMPD traits, which denote individual themes and styles of personality dysfunction.

SUMMARY

The dimensional personality disorder framework in ICD-11 and DSM-5-AMPD is largely compatible with the schema therapy model. The ICD-11 and DSM-5-AMPD provide a scientifically derived and theory-free framework for all practitioners, which may be connected to clinical theory of schema therapy in a coherent manner. Level of personality functioning can be conceptualized as healthy adult functioning (e.g. sense of identity, self-worth, emotion regulation, intimacy, and fulfillment), which inform intensity of treatment. Trait qualifiers can be conceptualized by associated modes (e.g., compliant surrender) and underlying schemas (e.g. abandonment), which inform focus and style of treatment.

Elucidating DSM-5 and ICD-11 Diagnostic Features of Borderline Personality Disorder Using Schemas and Modes

BACKGROUND

Borderline personality disorder (BPD) comprises a heterogeneous constellation of problems operationalized in the DSM-5 and the forthcoming ICD-11. In schema therapy, schemas and modes are employed to conceptualize and treat these problems.

AIM

The current study investigated whether the 9 diagnostic BPD features are associated with schemas and modes.

METHOD

Psychiatric outpatients with predominant BPD features (n = 142; 68% females) were administered the Structured Clinical Interview for DSM-IV Axis II (SCID-II) and self-report inventories for schemas and modes. Associations were investigated by means of bivariate point-biserial correlations and multiple logistic regression analysis.

RESULTS

BPD features were largely associated with conceptually related schemas and modes. Consistent with the schema therapy literature and previous research, we found schemas of Abandonment/Instability and Mistrust/Abuse along with modes of Angry/Enraged Child, (internalized) Punitive Parent, and Impulsive Child to uniquely predict thematically related BPD features including fear of abandonment, self-destructiveness, feelings of emptiness, stress-related paranoid ideation, inappropriate anger, and impulsivity.

CONCLUSION

Most of the 9 BPD features were related to conceptually meaningful schemas/modes, suggesting that BPD is composed of dormant themes along with salient affective-behavioral responses. Consequently, individual BPD features may be differentially conceptualized and targeted in therapy by means of schemas and modes.

Schemas and modes in borderline personality disorder: The mistrustful, shameful, angry, impulsive, and unhappy child

In this study we investigated how early maladaptive schemas and schema modes uniquely characterize Borderline Personality Disorder (BPD) patients versus comparison groups. BPD patients (n = 101) were systematically matched with personality disordered patients without BPD (n = 101) and healthy controls (n = 101). Differences were investigated using one-way ANOVA and multinomial logistic regression analyses. Results indicated that schemas of Mistrust/Abuse and Defectiveness/Shame along with modes of Angry Child, Impulsive Child, and (low) Happy Child uniquely differentiated BPD patients from patients with other personality disorders. Likewise, schemas of Mistrust/Abuse, Defectiveness/Shame, and Insufficient Self-Control along with modes of Vulnerable Child, Enraged Child, and (low) Happy Child, uniquely differentiated BPD patients from healthy controls. The results are overall consistent with propositions in the schema therapy literature as well as previous findings, and suggest that underlying schemas of Mistrust/Abuse and Defectiveness/Shame as well as manifest modes of Angry/Enraged Child, Impulsive Child, and (low) Happy Child comprise key features of BPD. Consequently, these features may be important foci in the conceptualization and treatment of BPD.

A new look at the schema therapy model: organization and role of early maladaptive schemas

This study reexamined the organization of Young's 18 early maladaptive schemas and their hypothesized associations with experiences of need-thwarting parental experiences in childhood and the "vulnerable child" mode of emotional distress in adulthood. A large Danish sample (N = 1054) of 658 clinical- and 391 nonclinical adults completed measures of early maladaptive schemas, parenting styles, and the vulnerable child mode. We identified four higher-order schema domains as most appropriate in terms of interpretability and empirical indices ("Disconnection & Rejection", "Impaired Autonomy & Performance", "Excessive Responsibility & Standards", and "Impaired Limits"). All four schema domains were differentially associated with conceptually relevant need-thwarting parental experiences. Apart from "Impaired Limits", the schema domains meaningfully accounted for the association between need-thwarting parental experiences in childhood and emotional states of feeling like a "vulnerable child" in adulthood. We conclude that four domains of early maladaptive schemas are empirically and conceptually consistent with Young's schema therapy model of personality pathology and longstanding emotional disorders. Findings warrant replication using different populations and if possible a prospective multi-method design. A scoring key for computing the four schema domains is provided.
