The Structural Validity of the YSQ-S3 and the YSQ-R: What Is the Way Forward for Schema Measurement?
Confirmatory Factor Analysis. Multistudy Report.
Karantzas et al. (2025).
-
Early Maladaptive Schemas (EMSs) are central to schema therapy and are most commonly measured by the Young Schema Questionnaire (YSQ). The short form (YSQ-S3) is widely used in both research and clinical contexts, but concerns remain about its structural validity, including inconsistent factor structures and poor model fit across studies. Recently, a revised version (YSQ-R) was introduced using Rasch analysis to improve psychometric properties, but its structural validity has not yet been thoroughly tested
-
Study 1: Systematic review of nine CFA studies (11 samples, N = 10,363) assessing the YSQ-S3 at the item level.
Study 2: Large-scale CFA (N = 995) testing the most common YSQ-S3 models identified in Study 1.
Study 3: CFA of the YSQ-R (N = 873), applying the same models used in Study 2
-
Study 1 found inconsistent results: some models achieved acceptable fit, but many demonstrated misfit across key indices.
Study 2 showed that none of the YSQ-S3 models tested achieved strong structural validity, with persistent issues of model misfit.
Study 3 demonstrated that, despite being designed to overcome limitations, the YSQ-R also failed to achieve satisfactory model fit
-
Both the YSQ-S3 and YSQ-R exhibit structural validity issues. The findings suggest that either (1) the items within these measures require revision, or (2) the conceptualization of EMSs within schema therapy needs to be reconsidered. This paper highlights an urgent need for re-evaluation of schema assessment tools to ensure reliable and valid measurement for both research and clinical practice.
Identifying the research priorities for schema therapy: A Delphi consensus study
Pilkington, P. D., Younan, R., & Karantzas, G. C. (2023)
-
Schema Therapy is widely used, but key gaps remain across its theory, measurement, and evidence base—making it hard to decide which questions should be tackled first. This project set out to define a clear, field-wide research agenda.
-
A three-round Delphi study gathered ratings from 56 international schema therapy experts (43 clinicians, 13 researchers). Potential research areas (n = 81) were generated from an interview with Jeffrey Young, a focus group with the ISST executive, and recommendations from recent reviews. Items were rated across three rounds; consensus was set at ≥75% endorsing “High/Very high priority.”
-
Nineteen priorities reached consensus, clustering into four themes:
Constructs & measures — e.g., clarifying overlaps/differences between EMSs, coping, modes, and attachment; developing work on core emotional needs. (Top items: 79%–77% priority.) ACU Research Bank
Testing theoretical assumptions — e.g., longitudinal research on how adversity, temperament, parenting, and gender relate to EMSs and modes. (75%–80%.) ACU Research Bank
Contexts & outcomes — priorities to examine effects on interpersonal and parenting outcomes. (86%, 77%.) ACU Research Bank
Effectiveness & mechanisms of change — strongest endorsements included:
Effectiveness for complex trauma (89%).
Identifying mechanisms of change (e.g., imagery, limited reparenting, mode work) (88%).
Trials with patients non-responsive to CBT (86%).
Multi-site RCTs and TAU comparisons (80% and 77%).
Trials in chronic depression/dysthymia; tests of whether ST changes EMSs/modes/coping; moderators and imagery research (all 75%–77%).
-
This Delphi consensus study established a clear roadmap for future schema therapy research. Experts from around the world highlighted the need to refine core constructs and measures, rigorously test theoretical assumptions about the development of schemas and modes, and explore schema therapy’s impact across interpersonal and parenting contexts. Importantly, there was strong consensus on advancing mechanism-of-change research and conducting large-scale, multi-site trials, particularly for complex trauma and treatment-resistant populations.
Together, these findings provide a shared set of priorities to guide researchers, clinicians, and funders in building a stronger, more cohesive evidence base for schema therapy.
The Associations Between Early Maladaptive Schemas and Adult Attachment Styles: A Meta-Analysis
A systematic review and meta-analysis. Clinical Psychology, Science & Practice.
Karantzas, G., Younan, R. & Pilkington, P.D (2022).
-
This article reports on the first meta-analysis into the relationships between attachment styles and early maladaptive schemas (EMS).
-
A systematic review and meta-analysis was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement, by searching the PsycINFO, PubMed, and CINAHL databases. Included studies were peer-reviewed journal articles that examined the relationship between one or more EMS and attachment styles.
-
Fifteen studies were included. All associations were estimated using a random-effects model. Overall, insecure attachment styles were significantly positively associated with EMS (anxious attachment r = .36, avoidant attachment r = .22, fearful attachment r = .28) and significantly negatively associated with secure attachment (r = .13). Subgroup analyses revealed differences in the magnitude of the associations between attachment styles and specific EMS. Anxious attachment demonstrated larger associations with EMS (compared to avoidant attachment) within the schema domains of disconnection/rejection (r = .49 vs. r = .31) and other-directedness (r = .32 vs. r = .12).
-
This study is the first quantitative review into the state of the field regarding the associations between adult attachment styles and early maladaptive schemas. The integration of adult attachment styles with early maladaptive schemas as part of this meta-analysis provides an important organizational framework regarding the maladaptive mental representations that insecure individuals harbor regarding their views of themselves and others. The findings provide therapists with an understanding of the maladaptive schemas that can feature in the presentation of clients who differ in attachment styles and how to tailor therapy to address the maladaptive schemas and coping patterns for different forms of attachment insecurity.
Adolescent maladaptive schemas and childhood abuse and neglect: A systematic review and meta-analysis
A Systematic Review and Meta-analysis. Clinical Psychology and Psychotherapy.
May, T., Younan, R., & Pilkington, P.D. (2022).
-
This study aimed to review evidence on the associations between childhood emotional, physical and sexual abuse; neglect and bullying and early maladaptive schemas, as measured in adolescence
-
PubMed, PsycInfo and CINAHL were searched to identify peer-reviewed studies reporting original quantitative data on the association
between early maladaptive schemas or schema domains (e.g., Disconnection and
Rejection) and childhood emotional, physical and sexual abuse; neglect and bullying,
measured in individuals aged up to 18 years. Meta-analyses were conducted to estimate the magnitude of the associations between schemas and childhood experiences. Twelve studies were included: Seven explored schemas, and five examined schema domains. Most studies had somewhat representative samples that were adequate in size, and all used validated measures of schemas or schema domains. Three studies explored emotional neglect, two each for emotional abuse, physical abuse and peer problems, one explored family violence and one adolescent stressors.
-
Metaanalyses indicated small to medium pooled associations between emotional abuse and Emotional Deprivation, r = .33 (95% CI [.19, .46]) and Subjugation, r = .32 (95% CI [.14,.47]) and emotional neglect and Mistrust Abuse, r = .41 (95% CI [.32, .49]), Abandonment, r = .25 (95% CI [.22, .28]), Social Isolation r = .23 (95% CI [.10, .35]) and Failure, r = .35 (95% CI [.26, .44]). Associations between childhood abuse and neglect experiences and schemas were evident in adolescents. There were limited data on some adverse experiences including sexual abuse and neglect.
-
The evidence thus far suggests that maladaptive schemas are related to experiences of childhoodemotional abuse and neglect and are evident before adulthood.
Early maladaptive schemas and depression in adulthood: A systematic review and meta-analysis
A systematic review and meta-analysis. Clinical Psychology & Psychotherapy, in press.
Bishop, A., Younan, R., Low, J., & Pilkington, P.D. (2021).
-
Improved understanding of the specific cognitive risk factors associated with depression is needed to inform prevention and treatment approaches. Recent research has examined the relationship between Early Maladaptive Schemas (EMS) and depression, but the findings were yet to be integrated using meta-analytic methods. The aim of this review was to synthesize the evidence on the relationship between depression and EMS.
-
A systematic review and meta-analysis was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement, by searching the PsycINFO, PubMed, and CINAHL databases. Included studies were peer-reviewed journal articles that examined the relationship between one or more EMS and depression in adulthood in participants aged 18 years or older.
-
A total of 51 studies were included (k = 743; Pooled N = 17,830). All 18 EMS were positively correlated with depression, with effect sizes ranging from small (r = .23 [.17, .29]; Entitlement) to large (r =.53 [.46, .60]; Social Isolation; r = .50, 95% CI [.45, .54]; Defectiveness/Shame).
-
The evidence suggests that individuals who feel like they do not belong, or that they are flawed, bad, or unlovable, report higher levels of depression. However, most studies used cross-sectional designs, and further longitudinal research is needed to establish the direction of the relationship between EMS and depression. These findings can guide preventative and treatment approaches. Focusing treatment on the Social Isolation and Defectiveness/Shame EMS may aid in relieving depressive symptoms.
Early maladaptive schemas and intimate partner violence victimization and perpetration
A Systematic Review and Meta-analysis. Clinical Psychology and Psychotherapy, in press.
Pilkington, P.D., Noonan. C., May, T., Holt R.A., & Younan, R. (2021).
-
Young's early maladaptive schemas represent a possible pathway between childhood adversity and Intimate Partner Violence (IPV). The evidence suggests that being a victim of IPV is associated with an expectation that one's needs for love and safety will not be met and doubt regarding one's capacity to handle responsibilities or succeed in life.
-
The aim of this review was to synthesize the evidence on early maladaptive schemas and IPV. PubMed, PsycInfo, and CINAHL databases were searched, in compliance with PRISMA, to identify peer reviewed studies that reported on the relationship between schema or schema domain scores and IPV victimization or perpetration.
-
Based on nine included studies, meta-analyses indicated that IPV victimization showed a moderate association with the Disconnection and Rejection and Impaired Autonomy domains, and a small association with Other-Directedness. The Mistrust Abuse and Vulnerability to Harm schemas were moderately correlated with victimization. Mistrust Abuse was also implicated in perpetration but insufficient data were available for meta-analysis.
-
The evidence suggests that being a victim of IPV is associated with an expectation that one's needs for love and safety will not be met and doubt regarding one's capacity to handle responsibilities or succeed in life.
Adverse childhood experiences and early maladaptive schemas in adulthood
A systematic review and meta-analysis.
Pilkington, P.D., Bishop, A., & Younan, R. (2020).
-
Schema Therapy is based on the theory that trauma and neglect in childhood lead to early maladaptive schemas and psychopathology in adulthood. The aim of this review was to evaluate support for this theory by synthesizing the literature on childhood adversity and schemas.
-
A systematic review and meta-analysis were completed in compliance with PRISMA. PsycInfo, CINAHL and PubMed were searched to identify eligible studies that reported unadjusted association(s) between adverse childhood events and schema scores when participants were 18 years or older. Meta-analyses were conducted to estimate the pooled effect size of associations between schemas and experiences of childhood adversity.
-
A total of 33 studies met inclusion criteria and provided sufficient data for meta-analyses on childhood experiences relating to toxic frustration of needs (emotional neglect and physical neglect) and trauma and victimization (emotional abuse, physical abuse and sexual abuse). Of the 124 meta-analyses, 65 indicated that schemas show small to large correlations with emotional neglect (range: r = .16 [Failure] to r = .51 [Emotional Deprivation]); small to moderate correlations with emotional abuse (range: r = .20 [Vulnerability to Harm] to r = .44 [Emotional Deprivation]); and small correlations with physical neglect, physical abuse and sexual abuse (range: r = .16 [Vulnerability to Harm] to .26 [Emotional Deprivation and Social Isolation]).
-
Of the 33 included studies, only one used a longitudinal design. However, based on the correlational studies available, early maladaptive schemas in adulthood are associated with a history of childhood abuse and neglect.
Early maladaptive schemas, suicidal ideation, and self-harm: a meta-analytic review
Pilkington, P.D., Bishop A., & Younan, R. (2021).
-
Understanding the risk factors for suicidality is essential to the prevention of death by suicide and the effective treatment of suicidal ideation and self-harm. The objective of this review was to summarise the evidence on the associations between suicidal ideation, suicidal or non-suicidal self-harm, and early maladaptive schemas.
-
A systematic review and meta-analysis was completed based on the PRISMA statement. Searches were conducted via PubMed, PsycInfo, and CINAHL. Included studies were peer-reviewed and reported on the bivariate association between one or more of the 18 schemas and either suicidal ideation or self-harm behavior.
-
We included 17 studies reporting more than 200 associations. Suicidal ideation demonstrated a large mean correlation with Defectiveness Shame (r = .50 [.43, .57]), moderate correlations with Social Isolation (r = .43 [.34, .50]), Failure (r =. 35 [.27, .42]), and Dependence Incompetence (r = .33 [.13, .51]), and small correlations with Subjugation (r = .26, [.13, 38]) and Emotional Inhibition (r = .29 [.13, .44]). Self-harm demonstrated small correlations with Emotional Deprivation (r = .21, [.13, .29]), Social Isolation (r = .29, [.18, .38]), and Emotional Inhibition (r = .19, [.13, .24]).
-
Confidence in the findings is limited by high heterogeneity across several analyses and the inability to investigate possible moderators due to the low number of included studies.
-
Believing that one is isolated, unlovable, or incapable is associated with an increased risk of suicidal thoughts. The findings correspond with the risk factors identified by the Interpersonal Theory of Suicide: thwarted belonging and burdensomeness.
A clinicians guide to evidence-based approaches: Narcissistic Personality Disorder
King, R. M., Grenyer, B. F. S ., & Younan, R. (2020).
-
Pathological narcissism has a long history dating back 2000 years, that has evolved into contemporary clinical psychology as a trait that may require clinical attention (Grenyer, 2013). Traditionally, Narcissistic personality disorder(NPD)is one of the 10 identified personality disorders in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5).
An alternative trait-based model of personality disorders in DSM-5 described in Section III includes a more contemporary version of NPD. The former NPD description only describes the grandiose form characterized by a grandiose sense of self-importance, fantasies of success, power etc, a belief in one’s specialness, desire for admiration, sense of entitlement, interpersonal exploitativeness, and lack of empathy. The alternative NPD alsodescribes impairments in functioning across identity, self-direction, empathy, and intimacy and while identifying pathological personality traits of grandiosity and attention seeking (both facets of antagonism) as well as more vulnerable narcissism presentations with aspects of negative affectivity such as depressivity and anxiousness (American Psychiatric Association, 2013). (see Pincus, Dowgwillo, & Greenberg (2016) for descriptions of 3 cases of NPD using the alternative DSM-5 model).
Thus, contemporary views of pathological narcissism recognise both grandiose and vulnerable components.
‘Teaching Me to Parent Myself’: The Feasibility of an In-Patient Group Schema Therapy Programme for Complex Trauma
May, T., Farrell, J., & Younan, R. (2017).
-
Group schema therapy is an emerging treatment for personality and other psychiatric disorders. It may be particularly suited to individuals with complex trauma given that early abuse is likely to create maladaptive schemas.
-
This pilot study explored the feasibility and effectiveness of a 4-week in-patient group schema therapy programme for adults with complex trauma in a psychiatric hospital setting.
-
Thirty-six participants with complex trauma syndrome participated in this open trial. Treatment consisted of 60 hours of group schema therapy and 4 hours of individual schema therapy administered over 4 weeks. Feasibility measures included drop-out rates, qualitative interviews with participants to determine programme acceptability and measures of psychiatric symptoms, self-esteem, quality of life and schema modes pre-, post- and 3 months following the intervention.
-
Drop-out rate for the 4-week program was 11%. Thematic analysis of interview transcripts revealed four major themes: connection, mode language explained emotional states, identifying the origin of the problem and the emotional activation of the programme. Measures of psychiatric symptoms, self-esteem and quality of life showed improvement post-treatment and at 3 months post-treatment. There was a reduction in most maladaptive schema modes pre-/post-treatment. Conclusions: A group schema therapy approach for complex trauma is feasible and demonstrates positive effects on psychiatric symptoms and maladaptive schemas.
-
A group schema therapy approach for complex trauma is feasible and demonstrates positive effects on psychiatric symptoms and maladaptive schemas.
