RESUMEN

Several decades of theory suggest that pathological narcissism (PN) may limit psychotherapy success, but empirical evidence for such theories is limited and mixed. In addition, it has been proposed that individuals with high levels of PN may benefit more from supportive compared to interpretive psychodynamic therapies, but no studies thus far have investigated this question empirically. As such, our study aimed to extend past research by investigating (a) whether higher levels of pretreatment PN predict poorer treatment outcome and (b) whether the type of psychodynamic therapy (supportive or interpretive therapy) moderates these findings, in a sample of patients undergoing group psychodynamic psychotherapy for perfectionism. The sample was drawn from the University of British Columbia Perfectionism Treatment Study II (Hewitt et al., 2023) and consisted of 80 treatment-seeking adults with elevated perfectionism. Contrary to expectations, multilevel and multiple regression analyses showed that pretreatment PN did not significantly predict posttreatment changes in symptom severity, life satisfaction, or work and social impairment. We also did not find that either grandiose or vulnerable narcissism predicted likelihood of patient dropout. Finally, treatment type did not moderate the relationship between pretreatment PN and treatment outcome, suggesting that, contrary to our hypotheses, PN does not impact treatment outcome regardless of the interpretive nature of the psychodynamic group therapy. These results, taken together with past findings, suggest that PN may not be associated with poorer psychotherapy outcomes in certain contexts, such as in the case of supportive or interpretive psychodynamic group psychotherapy for perfectionism.

RESUMEN

Objective: This randomized controlled trial investigated the efficacy of dynamic relational group therapy (DRT) relative to group psychodynamic supportive therapy (PST) in improving perfectionism-related attitudes and components of the perfectionistic self-relationship. Method: Based on a comprehensive conceptualization of perfectionism, 80 community-recruited, highly perfectionistic individuals were randomly allocated to 12 sessions of group DRT (n = 41; 5 groups) or group PST (n = 39; 5 groups). Patients completed measures of dysfunctional attitudes, self-criticism, self-esteem, and self-reassurance at pre-, mid-, and post-treatment, and six months post-treatment. Results: Multigroup latent growth curve modeling revealed significant (p < .05) decreases in dysfunctional attitudes, concern over mistakes, two types of self-criticism, and self-esteem problems, along with a significant increase in self-reassurance, from pre-treatment to six-month follow-up in both DRT and PST. Moderate-to-large between-group differences favoring DRT over PST were found for dysfunctional attitudes and self-reassurance. A majority of patients in both conditions maintained reliable improvement at six-month follow-up in dysfunctional attitudes, concern over mistakes, and self-criticism focused on inadequacy. Conclusion: Findings provide evidence for the use of psychodynamic group therapy approaches in treating perfectionism-related attitudes and self-relational elements of perfectionism, and support the relative efficacy of DRT for dysfunctional attitudes and self-reassurance.

RESUMEN

This article introduces a measure of self-condemnatory internal dialogue as an element of the relationship with the self: The Automatic Self-Recrimination Scale (ASRS). Using the construct validation approach to test construction, we describe the initial development of items and report on findings from a clinical and nonclinical sample showing the ASRS is best understood as a multidimensional measure of self-critical internal dialogue composed of one higher-order factor and four lower-order facets: Not Mattering, Self as Failure, Undeserving Self, and Loathsomeness. The overall scale and four subscales demonstrated acceptable internal consistency and test-retest reliability. Moreover, there was evidence of good convergent and incremental validity of the ASRS subscales with measures of perfectionism, self-criticism, and dysfunctional attitudes. Overall, the ASRS appears to be a reliable and valid measure of an automatic self-recriminatory internal dialogue.

RESUMEN

In BCR-ABL1 lymphoblastic leukemia, treatment heterogeneity to tyrosine kinase inhibitors (TKIs), especially in the absence of kinase domain mutations in BCR-ABL1, is poorly understood. Through deep molecular profiling, we uncovered three transcriptomic subtypes of BCR-ABL1 lymphoblastic leukemia, each representing a maturation arrest at a stage of B-cell progenitor differentiation. An earlier arrest was associated with lineage promiscuity, treatment refractoriness and poor patient outcomes. A later arrest was associated with lineage fidelity, durable leukemia remissions and improved patient outcomes. Each maturation arrest was marked by specific genomic events that control different transition points in B-cell development. Interestingly, these events were absent in BCR-ABL1+ preleukemic stem cells isolated from patients regardless of subtype, which supports that transcriptomic phenotypes are determined downstream of the leukemia-initialing event. Overall, our data indicate that treatment response and TKI efficacy are unexpected outcomes of the differentiation stage at which this leukemia transforms.

RESUMEN

BACKGROUND & AIMS: Pancreatic ductal adenocarcinoma (PDA), with its highly metastatic propensity, is one of the most lethal subtypes of pancreatic cancer. Although recent large-scale transcriptomic studies have demonstrated that heterogeneous gene expressions play an essential role in determining molecular phenotypes of PDA, biological cues for and consequences of distinct transcriptional programs remain unclear. METHODS: We developed an experimental model that enforces the transition of PDA cells toward a basal-like subtype. We combined epigenome and transcriptome analyses with extensive in vitro and in vivo evaluations of tumorigenicity to demonstrate the validity of basal-like subtype differentiation in association with endothelial-like enhancer landscapes via TEA domain transcription factor 2 (TEAD2). Finally, we used loss-of-function experiments to investigate the importance of TEAD2 in regulating reprogrammed enhancer landscape and metastasis in basal-like PDA cells. RESULTS: Aggressive characteristics of the basal-like subtype are faithfully recapitulated in vitro and in vivo, demonstrating the physiological relevance of our model. Further, we showed that basal-like subtype PDA cells acquire a TEAD2-dependent proangiogenic enhancer landscape. Genetic and pharmacologic inhibitions of TEAD2 in basal-like subtype PDA cells impair their proangiogenic phenotypes in vitro and cancer progression in vivo. Last, we identify CD109 as a critical TEAD2 downstream mediator that maintains constitutively activated JAK-STAT signaling in basal-like PDA cells and tumors. CONCLUSIONS: Our findings implicate a TEAD2-CD109-JAK/STAT axis in the basal-like differentiated pancreatic cancer cells and as a potential therapeutic vulnerability.

RESUMEN

OBJECTIVE: This randomized controlled trial investigated the efficacy of group dynamic-relational therapy (DRT) relative to group psychodynamic supportive therapy (PST) in treating perfectionism and improving psychological functioning. HYPOTHESIS: Psychodynamically informed therapies, particularly DRT, will be efficacious in treating perfectionism and functioning outcomes. METHOD: Based on a comprehensive conceptualization of perfectionism, 80 community-recruited, highly perfectionistic individuals were randomly allocated to 12 sessions of group DRT (n = 41; 5 groups) or group PST (n = 39; 5 groups). Patients completed measures of trait perfectionism, perfectionistic self-presentation, perfectionistic cognitions, symptom distress, life satisfaction, and work and social adjustment at pre-, mid-, and posttreatment and 6 months posttreatment. RESULTS: Multigroup latent growth curve modeling revealed significant (p < .05) decreases in all perfectionism components and improvements in all functioning outcomes from pretreatment to 6-month follow-up in both DRT and PST. Likewise, analyses revealed substantial reliable improvement across conditions for all perfectionism components. Last, moderate-to-large between-group differences favoring DRT over PST were found for self-oriented perfectionism, perfectionistic self-promotion, nondisplay of imperfection, nondisclosure of imperfection, and work and social adjustment. CONCLUSION: Findings provide evidence for the use of psychodynamic approaches in the treatment of perfectionism and support the relative efficacy of DRT for components of perfectionism.

RESUMEN

The interest in treating underlying core vulnerability factors or transdiagnostic processes has been a focus of much attention. In this paper we describe our application of group dynamic-relational psychotherapy to the treatment of perfectionism, a core personality vulnerability factor associated with various forms and types of dysfunction and disorders that have profound costs to the individual both socially and subjectively. Over the course of the past three decades, we developed an evidence-based integrative group treatment that targets the psychodynamic and relational underpinnings of perfectionism. The treatment is based on an integration of psychodynamic and interpersonal perspectives and therapeutic approaches. In this paper we present our model of perfectionism and describe our group dynamic-relational therapy for the treatment of its pernicious outcomes. By drawing on illustrative case material, we describe the approach as applied to one such group as it progresses through four phases of group development that we have termed engagement and pseudo attachment, pattern interruption, self-redefinition/painful authenticity, and termination. Finally, we present some of the accumulating evidence of the effectiveness and efficacy of dynamic-relational therapy.

RESUMEN

BACKGROUND: The incidence of depression in human females rises steadily throughout adolescence, a critical period of pubertal maturation marked by increasing levels of gonadal hormones including estrogens and progesterone. These gonadal hormones play a central role in social and emotional development and may also contribute to the increased occurrence of depression in females that begins in early adolescence. In this study, we examine whether and how introducing synthetic estrogen and progestin derivatives through the use of combined hormonal contraceptives (CHC), affects adolescent females' risk for developing depression. We further assess potential links between CHC use and alterations in stress responses and social-emotional functioning. METHODS: Using a longitudinal cohort design, we will follow a sample of adolescent females over the span of three years. Participants will be assessed at three time points: once when they are between 13 and 15 years of age, and at approximately 18 and 36 months after their initial assessment. Each time point will consist of two online sessions during which participants will complete a clinical interview that screens for key symptoms of mental health disorders, along with a series of questionnaires assessing their level of depressive symptoms and history of contraceptive use. They will also complete a standardized social-evaluative stress test and an emotion recognition task, as well as provide saliva samples to allow for assessment of their circulating free cortisol levels. DISCUSSION: In this study we will assess the effect of CHC use during adolescence on development of Major Depressive Disorder (MDD). We will control for variables previously found to or proposed to partially account for the observed relationship between CHC use and MDD, including socioeconomic status, age of sexual debut, and CHC-related variables including age of first use, reasons for use, and its duration. In particular, we will discover whether CHC use increases depressive symptoms and/or MDD, whether elevated depressive symptoms and/or MDD predict a higher likelihood of starting CHC, or both. Furthermore, this study will allow us to clarify whether alterations in stress reactivity and social-emotional functioning serve as pathways through which CHC use may result in increased risk of depressive symptoms and/or MDD.
