RESUMO

OBJECTIVE: Despite research, national legislation, and clinical guidelines supporting transitional care, there is minimal benefit from existing transitional care interventions for racial/ethnic minorities with traumatic brain injury (TBI) discharged home from acute hospital care. Existing TBI transitional care interventions are not tailored to address the needs/preferences of patients from various racial/ethnic minority groups. The purpose of this study was to describe use of personalization to tailor a TBI transitional care intervention for various racial/ethnic groups. DESIGN: Following preliminary intervention manual development, a qualitative descriptive study was conducted using eight focus groups with 40 English-and Spanish-speaking participants (12 patients, 12 caregivers, and 16 providers). RESULTS: Three personalization-related themes emerged: 1) what is important to me, 2) finding someone to deliver the intervention who can adapt to my needs, and 3) respect over culture. Findings informed personalization strategies within our final manual. CONCLUSIONS: We recommend researchers who wish to use personalization to tailor interventions to consider: 1) allowing stakeholders to dictate what is most important and 2) implementing an iterative intervention development process with input from diverse stakeholders. Findings have implications for informing the development of transitional care interventions to increase the likelihood that interventions are inclusive of needs and preferences of various races/ethnicities.

RESUMO

BACKGROUND: Approximately 40% of Emergency Department (ED) patients with chest pain meet diagnostic criteria for panic-related anxiety, but only 1-2% are correctly diagnosed and appropriately managed in the ED. A stepped-care model, which focuses on providing evidence-based interventions in a resource-efficient manner, is the state-of-the art for treating panic disorder patients in medical settings such as primary care. Stepped-care has yet to be tested in the ED setting, which is the first point of contact with the healthcare system for most patients with panic symptoms. METHODS: This multi-site randomized controlled trial (RCT) aims to evaluate the clinical, patient-centred, and economic effectiveness of a stepped-care intervention in a sample of 212 patients with panic-related anxiety presenting to the ED of Singapore's largest public healthcare group. Participants will be randomly assigned to either: 1) an enhanced care arm consisting of a stepped-care intervention for panic-related anxiety; or 2) a control arm consisting of screening for panic attacks and panic disorder. Screening will be followed by baseline assessments and blocked randomization in a 1:1 ratio. Masked follow-up assessments will be conducted at 1, 3, 6, and 12 months. Clinical outcomes will be panic symptom severity and rates of panic disorder. Patient-centred outcomes will be health-related quality of life, daily functioning, psychiatric comorbidity, and health services utilization. Economic effectiveness outcomes will be the incremental cost-effectiveness ratio of the stepped-care intervention relative to screening alone. DISCUSSION: This trial will examine the impact of early intervention for patients with panic-related anxiety in the ED setting. The results will be used to propose a clinically-meaningful and cost-effective model of care for ED patients with panic-related anxiety. TRIAL REGISTRATION: ClinicalTrials.gov NCT03632356.

RESUMO

The central goal of clinical psychology is to reduce the suffering caused by mental health conditions. Anxiety, mood, psychosis, substance use, personality, and other mental disorders impose an immense burden on global public health and the economy. Tackling this burden will require the development and dissemination of intervention strategies that are more effective, sustainable, and equitable. Clinical psychology is uniquely poised to serve as a transdisciplinary hub for this work. But rising to this challengerequires an honest reckoning with the strengths and weaknesses of current training practices. Building on new data, we identify the most important challenges to training the next generation of clinical scientists. We provide specific recommendations for the full spectrum of stakeholders-from funders, accreditors, and universities to program directors, faculty, and students-with an emphasis on sustainable solutions that promote scientific rigor and discovery and enhance the mental health of clinical scientists and the public alike.

RESUMO

BACKGROUND: Substance use is a major risk factor for negative health and functioning outcomes among middle schoolers. The purpose of this study was to assess whether individual differences in the adolescents' goal orientation are associated with elevated or attenuated risk for substance use. Regulatory focus theory stipulates that individuals vary in their strength of orientation toward promotion goals ("making good things happen") and prevention goals ("keeping bad things from happening"). Objectives: We sought to examine the association between individual differences in regulatory focus and adolescents' reports of their own and their friends' substance use. Methods: Participants were 241 seventh grade students who completed measures of regulatory focus (promotion and prevention orientation), self-reported substance use, perceived substance use habits of peers, and demographics. Logistic regression models were used to examine adjusted odds of lifetime tobacco use, alcohol use, and marijuana use for both participants' own use and their reports of friends' use. Results: Prevention orientation was associated with lower odds of all self-reported lifetime substance use outcomes (tobacco, alcohol, and marijuana). Prevention orientation was also associated with lower odds of reporting all types of substance use among friends. Promotion orientation was not associated with any self-reported substance use outcome, and was only associated with higher odds of reporting lifetime alcohol use among friends. Conclusions: These findings underscore the importance of regulatory focus as it relates to adolescent substance use. Future research may seek to incorporate regulatory focus within interventions intended to prevent or delay initiation of substance use in adolescents.

RESUMO

PURPOSE: Self-discrepancy (i.e., perceived differences between one's actual self and personal standards) has been associated with binge eating disorder (BED) symptoms. However, little is known about how weight discrepancy (i.e., the difference between one's actual and ideal weights) interacts with or is distinguished from nonappearance self-discrepancy (discrepancy unrelated to weight or shape) in predicting BED severity. The current study examined how these two forms of discrepancy independently and interactively relate to BED and associated symptoms to elucidate how facets of self-discrepancy may operate to precipitate and maintain BED. METHODS: Adults with BED (N = 111) completed questionnaires and interviews prior to treatment that assessed self-discrepancy (computerized selves) and weight discrepancy (assessed during the Eating Disorder Examination [EDE]) as predictors of global eating disorder (ED) symptomatology (EDE Global score), depression (Beck Depression Inventory), anxiety (State-Trait Anxiety Inventory), self-esteem (Rosenberg Self-Esteem Scale), and ED-related impairment (Clinical Impairment Assessment). RESULTS: Multivariate regression models indicated nonappearance self-discrepancy and weight discrepancy were not significantly related to the severity of global ED symptoms, but both independently predicted impairment (ps < 0.05). Nonappearance self-discrepancy, but not weight discrepancy, was also associated with higher depression (p = 0.001), anxiety (p < 0.001), and lower self-esteem (p < 0.001). CONCLUSION: These findings suggest distinct associations of weight discrepancy and nonappearance self-discrepancy with ED and related symptoms, as well as each of these constructs' relevance to everyday functioning in BED. The results also highlight potential avenues for future research to examine mechanistic pathways by which self-discrepancy influences BED severity. LEVEL OF EVIDENCE: V, descriptive cross-sectional study.

RESUMO

BACKGROUND: Individuals with extreme food avoidance such as Avoidant Restrictive Food Intake Disorder (ARFID) experience impairing physical and mental health consequences from nutrition of insufficient variety or/and quantity. Identifying mechanisms contributing to food avoidance is essential to develop effective interventions. Anxiety figures prominently in theoretical models of food avoidance; however, there is limited evidence that repeated exposures to foods increases approach behavior in ARFID. Studying disgust, and relationships between disgust and anxiety, may offer novel insights, as disgust is functionally associated with avoidance of contamination from pathogens (as may occur via ingestion) and is largely resistant to extinction. METHOD: This exploratory, cross-sectional study included data from 1,644 adults who completed an online questionnaire. Participant responses were used to measure ARFID classification, picky eating, sensory sensitivity, disgust, and anxiety. Structural equation modeling tested a measurement model of latent disgust and anxiety factors as measured by self-reported frequency of disgust and anxiety reactions. Mediational models were used to explore causal ordering. RESULTS: A latent disgust factor was more strongly related to severity of picky eating (B ≈ 0.4) and ARFID classification (B ≈ 0.6) than the latent anxiety factor (B ≈ 0.1). Disgust partially mediated the association between anxiety and picky eating and fully mediated the association between anxiety and ARFID. Models testing the reverse causal ordering demonstrated poorer fit. Findings suggest anxiety may be associated with food avoidance in part due to increased disgust. CONCLUSIONS: Disgust may play a prominent role in food avoidance. Findings may inform novel approaches to treatment.

RESUMO

OBJECTIVES: Despite the growing use of repetitive transcranial magnetic stimulation (rTMS) as a treatment for unipolar depression, its typical effect sizes have been modest, and methodological and conceptual challenges remain regarding how to optimize its efficacy. Linking rTMS to a model of the neurocircuitry underlying depression and applying such a model to personalize the site of stimulation may improve the efficacy of rTMS. Recent developments in the psychology and neurobiology of self-regulation offer a conceptual framework for identifying mechanisms of action in rTMS for depression, as well as for developing guidelines for individualized rTMS treatment. We applied this framework to develop a multimodal treatment for depression by pairing self-system therapy (SST) with simultaneously administered rTMS delivered to an individually targeted region of dorsolateral prefrontal cortex identified via functional magnetic resonance imaging (fMRI). METHODS: In this proof-of-concept study, we examined the acceptability, feasibility, and preliminary efficacy of combining individually fMRI-targeted rTMS with SST. Using the format of a cognitive paired associative stimulation paradigm, the treatment was administered to 5 adults with unipolar depression in an open-label trial. RESULTS: The rTMS/SST combination was well tolerated, feasible, and acceptable. Preliminary evidence of efficacy also was promising. We hypothesized that both treatment modalities were targeting the same neural circuitry through cognitive paired associative stimulation, and observed changes in task-based fMRI were consistent with our model. These neural changes were directly related to improvements in depression severity. CONCLUSIONS: The new combination treatment represents a promising exemplar for theory-based, individually targeted, multimodal intervention in mood disorders.

RESUMO

The standard clinical technique for using repetitive transcranial magnetic stimulation (rTMS) for major depressive disorder (MDD) is associated with limited efficacy to date. Such limited efficacy may be due to reliance on scalp-based targeting rather than state-of-the-science methods which incorporate fMRI-guided neuronavigation based on a specific model of neurocircuit dysfunction. In this review, we examine such a specific model drawn from regulatory focus theory, which postulates two brain/behavior systems, the promotion and prevention systems, underlying goal pursuit. Individual differences in these systems have been shown to predict vulnerability to MDD as well as to comorbid generalized anxiety disorder (GAD). Activation of an individual's promotion or prevention goals via priming leads to motivational and affective responses modulated by the individual's appraisal of their progress in attaining the goal. In addition, priming promotion vs. prevention goals induces discriminable patterns of brain activation that are sensitive to the effects of depression and anxiety: MDD is associated with promotion system failure, anhedonic/dysphoric symptoms, and hypoactivation in specific regions in left prefrontal cortex, whereas GAD is associated with prevention system failure, hypervigilant/agitated symptoms, and hyperactivation in right prefrontal cortex (PFC). These left and right PFC locations can be directly targeted in an individualized manner for TMS. Additionally, this individually targeted rTMS can be integrated with cognitive interventions designed to activate the neural circuitry associated with promotion vs. prevention, thus allowing the neuroplasticity induced by the rTMS to benefit the systems likely to be involved in remediating depression. Targeted engagement of cortical systems involved in emotion regulation using individualized fMRI guidance may help increase the efficacy of rTMS in depression.

RESUMO

This article presents a general framework in which different manifestations of psychopathology can be conceptualized as dysfunctions in one or more mechanisms of self-regulation, defined as the ongoing process of managing personal goal pursuit in the face of internal, interpersonal, and environmental forces that would derail it. The framework is based on the assertion that self-regulation is a critical locus for the proximal influence on motivation, cognition, emotion, and behavior of more distal factors such as genetics, temperament, socialization history, and neurophysiology. Psychological theories of self-regulation are ideal platforms from which to integrate the study of self-regulation both within and across traditional disciplines. This article has two related goals: to elucidate how the construct of self-regulation provides a unique conceptual platform for the study of psychopathology and to illustrate that platform by presenting our research on depression as an example.

RESUMO

This study examined self-discrepancy, a construct of theoretical relevance to eating disorder (ED) psychopathology, across different types of EDs. Individuals with anorexia nervosa (AN; n = 112), bulimia nervosa (BN; n = 72), and binge eating disorder (BED; n = 199) completed semi-structured interviews assessing specific types of self-discrepancies. Results revealed that actual:ideal (A:I) discrepancy was positively associated with AN, actual:ought (A:O) discrepancy was positively associated with BN and BED, and self-discrepancies did not differentiate BN from BED. Across diagnoses, A:O discrepancy was positively associated with severity of purging, binge eating, and global ED psychopathology. Further, there were significant interactions between diagnosis and A:O discrepancy for global ED psychopathology and between diagnosis and A:I discrepancy for binge eating and driven exercise. These results support the importance of self-discrepancy as a potential causal and maintenance variable in EDs that differentiates among different types of EDs and symptom severity.

RESUMO

OBJECTIVE: Persistent low back pain (PLBP) is associated with vulnerability to depression. PLBP frequently requires major changes in occupation and lifestyle, which can lead to a sense of failing to attain one's personal goals (self-discrepancy). METHOD: We conducted a clinical trial to examine the efficacy of self-system therapy (SST), a brief structured therapy for depression based on self-discrepancy theory. A total of 101 patients with PLBP and clinically significant depressive symptoms were randomized either to SST, pain education, or standard care. RESULTS: Patients receiving SST showed significantly greater improvement in depressive symptoms. Reduction in self-discrepancy predicted reduction in depressive symptoms only within the SST condition. CONCLUSIONS: Findings support the utility of SST for individuals facing persistent pain and associated depression.

RESUMO

OBJECTIVE: This article reviews neuroimaging studies that inform psychotherapy research. An introduction to neuroimaging methods is provided as background for the increasingly sophisticated breadth of methods and findings appearing in psychotherapy research. METHOD: We compiled and assessed a comprehensive list of neuroimaging studies of psychotherapy outcome, along with selected examples of other types of studies that also are relevant to psychotherapy research. We emphasized magnetic resonance imaging (MRI) since it is the dominant neuroimaging modality in psychological research. RESULTS: We summarize findings from neuroimaging studies of psychotherapy outcome, including treatment for depression, obsessive compulsive disorder (OCD), and schizophrenia. CONCLUSIONS: The increasing use of neuroimaging methods in the study of psychotherapy continues to refine our understanding of both outcome and process. We suggest possible directions for future neuroimaging studies in psychotherapy research.

RESUMO

OBJECTIVE: Psychotherapy for depression emphasizes techniques that can help individuals regulate their moods. The present study investigated the affective impact and electrocortical correlates of cognitive restructuring, delivered as a 90-minute psychotherapeutic microintervention in a dysphoric sample. METHOD: Participants (N = 92) who reported either low or high levels of dysphoric symptoms were randomly assigned to the restructuring microintervention, a control intervention or a no-intervention condition. We obtained recordings of event-related potentials (ERPs) as well as mood self-ratings during an experimental session immediately after the psychotherapeutic microintervention and the control intervention in which a set of negatively valenced pictures (IAPS) was presented with different instructions. RESULTS: Whereas the restructuring intervention group and the control intervention group reported both increases in positive and decreases in negative affect from pre- to post-intervention, the three groups differed significantly on ERP measures. CONCLUSIONS: Findings provide support for current models of mechanisms of action in cognitive therapies.

RESUMO

Regulatory focus theory (RFT) describes two cognitive-motivational systems for goal pursuit-the promotion and prevention systems-important for self-regulation and previously implicated in vulnerability to psychopathology. According to RFT, the promotion system is engaged in attaining ideal goals (e.g. hopes and dreams), whereas the prevention system is associated with accomplishing ought goals (e.g. duties and obligations). Prior task-based functional magnetic resonance imaging (fMRI) studies have mostly explored the mapping of these two systems onto the activity of a priori brain regions supporting motivation and executive control in both healthy and depressed adults. However, complex behavioral processes such as those guided by individual differences in regulatory focus are likely supported by widely distributed patterns of intrinsic functional connectivity. We used data-driven connectome-based predictive modeling to identify patterns of distributed whole-brain intrinsic network connectivity associated with individual differences in promotion and prevention system orientation in 1,307 young university volunteers. Our analyses produced a network model predictive of prevention but not promotion orientation, specifically the subjective experience of successful goal pursuit using prevention strategies. The predictive model of prevention success was highlighted by decreased intrinsic functional connectivity of both heteromodal association cortices in the parietal and limbic networks and the primary motor cortex. We discuss these findings in the context of strategic inaction, which drives individuals with a strong dispositional prevention orientation to inhibit their behavioral tendencies in order to shield the self from potential losses, thus maintaining the safety of the status quo but also leading to trade-offs in goal pursuit success.

RESUMO

Psychotherapy is a complex, multilayered process with the potential to bring about changes at multiple levels of functioning, from the neurobiology of the brain to the individual's role in the social world. Although studies of the mechanisms by which psychotherapy leads to change continue to appear, there remains much to be learned about how psychological interventions work. To guide explorations of how and for whom particular treatment approaches lead to change, researchers can rely on theory to identify potential loci for change and on translational research methods to integrate basic behavioral science and neuroscience with clinical science. In this article, we describe research linking individual differences in the self-regulation of personal goal pursuit with the etiology and treatment of mood disorders. The research draws upon regulatory focus theory as a model of self-regulation and on microintervention designs-controlled laboratory investigations of a specific therapeutic technique-to generate and test hypotheses about how psychological interventions can help to reverse maladaptive self-regulatory processes.

RESUMO

Failure to make progress toward personal goals can lead to negative affective states, such as depression and anxiety. Past research suggests that rumination in response to goal failure may prolong and intensify those acute emotional responses, but that process remains unclear. We examined ruminative thought processes following experimentally manipulated exposure to past failures to attain advancement (promotion) goals and safety (prevention) goals. We predicted that priming of past promotion and prevention goal failures would lead individuals to think repetitively about these failures and that negative affect would be evoked by their recognition of their failures. Further, we predicted that when people experience a sufficient magnitude of negative affect, ruminative thought would intensify and prolong the negative affect associated with that type of goal failure. Results yielded strong support for our predictions regarding promotion goal failure and modest support for those regarding prevention goal failure.

RESUMO

Self-regulation denotes the processes by which people initiate, maintain, and control their own thoughts, behaviors, or emotions to produce a desired outcome or avoid an undesired outcome. Self-regulation brings the influence of distal factors such as biology, temperament, and socialization history onto cognition, motivation, and behavior. Dysfunction in self-regulation represents a contributory causal factor for psychopathology. Accordingly, we previously proposed a risk phenotype model for depression drawing from regulatory focus theory and traditional task-based fMRI studies. In this article, we revise and expand our risk phenotype model using insights from new methodologies allowing quantification of individual differences in task-free macroscale brain organization. We offer a set of hypotheses as examples of how examination of intrinsic macroscale brain organization can extend and enrich investigations of self-regulation and depression. In doing so, we hope to promote a useful heuristic for model development and for identifying transdiagnostic risk phenotypes in psychopathology.

RESUMO

Interventions to preserve functional independence in older adults are critically needed to optimize 'successful aging' among the large and increasing population of older adults in the United States. For most aging adults, the management of chronic diseases is the most common and impactful risk factor for loss of functional independence. Chronic disease management inherently involves the learning and adaptation of new behaviors, such as adopting or modifying physical activity habits and managing weight. Despite the importance of chronic disease management in older adults, vanishingly few individuals optimally manage their health behavior in the service of chronic disease stabilization to preserve functional independence. Contemporary conceptual models of chronic disease management and health habit theory suggest that this lack of optimal management may result from an underappreciated distinction within the health behavior literature: the behavioral domains critical for initiation of new behaviors (Initiation Phase) are largely distinct from those that facilitate their maintenance (Maintenance Phase). Psychological factors, particularly experiential acceptance and trait levels of openness are critical to engagement with new health behaviors, willingness to make difficult lifestyle changes, and the ability to tolerate aversive affective responses in the process. Cognitive factors, particularly executive function, are critical to learning new skills, using them effectively across different areas of life and contextual demands, and updating of skills to facilitate behavioral maintenance. Emerging data therefore suggests that individuals with greater executive function are better able to sustain behavior changes, which in turn protects against cognitive decline. In addition, social and structural supports of behavior change serve a critical buffering role across phases of behavior change. The present review attempts to address these gaps by proposing a novel biobehavioral intervention framework that incorporates both individual-level and social support system-level variables for the purpose of treatment tailoring. Our intervention framework triangulates on the central importance of self-regulatory functioning, proposing that both cognitive and psychological mechanisms ultimately influence an individuals' ability to engage in different aspects of self-management (individual level) in the service of maintaining independence. Importantly, the proposed linkages of cognitive and affective functioning align with emerging individual difference frameworks, suggesting that lower levels of cognitive and/or psychological flexibility represent an intermediate phenotype of risk. Individuals exhibiting self-regulatory lapses either due to the inability to regulate their emotional responses or due to the presence of executive functioning impairments are therefore the most likely to require assistance to preserve functional independence. In addition, these vulnerabilities will be more easily observable for individuals requiring greater complexity of self-management behavioral demands (e.g. complexity of medication regimen) and/or with lesser social support. Our proposed framework also intuits several distinct intervention pathways based on the profile of self-regulatory behaviors: we propose that individuals with intact affect regulation and impaired executive function will preferentially respond to 'top-down' training approaches (e.g., strategy and process work). Individuals with intact executive function and impaired affect regulation will respond to 'bottom-up' approaches (e.g., graded exposure). And individuals with impairments in both may require treatments targeting caregiving or structural supports, particularly in the context of elevated behavioral demands.

RESUMO

Background: Despite the growing use of repetitive transcranial magnetic stimulation (rTMS) as a treatment for depression, there is a limited understanding of the mechanisms of action and how potential treatment-related brain changes help to characterize treatment response. To address this gap in understanding we investigated the effects of an approach combining rTMS with simultaneous psychotherapy on global functional connectivity. Method: We compared task-related functional connectomes based on an idiographic goal priming task tied to emotional regulation acquired before and after simultaneous rTMS/psychotherapy treatment for patients with major depressive disorders and compared these changes to normative connectivity patterns from a set of healthy volunteers (HV) performing the same task. Results: At baseline, compared to HVs, patients demonstrated hyperconnectivity of the DMN, cerebellum and limbic system, and hypoconnectivity of the fronto-parietal dorsal-attention network and visual cortex. Simultaneous rTMS/psychotherapy helped to normalize these differences, which were reduced after treatment. This finding suggests that the rTMS/therapy treatment regularizes connectivity patterns in both hyperactive and hypoactive brain networks. Conclusions: These results help to link treatment to a comprehensive model of the neurocircuitry underlying depression and pave the way for future studies using network-guided principles to significantly improve rTMS efficacy for depression.
