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.

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

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. Retrospectively registered 15 August 2018.

RESUMO

BACKGROUND: For patients and their intimate partners, advanced cancer poses significant challenges that can negatively impact both individuals and their relationship. Prior studies have found evidence that couple-based communication skills interventions can to be beneficial for patients and partners. However, these studies have been limited by reliance on in-person treatment delivery and have not targeted couples at high risk for poor outcomes. This study tests the efficacy of a Couples Communication Skills Training (CCST) intervention delivered via videoconference for couples reporting high levels of holding back from discussing cancer-related concerns, a variable associated with poorer psychological and relationship functioning. METHODS: This RCT is designed to evaluate the efficacy of CCST in improving patient and partner relationship functioning (primary outcome). Secondary outcomes include patient and partner psychological functioning and patient symptoms and health care use. We also examine the role of objective and self-reported communication behaviors as mediators of treatment effects. Two hundred thirty patients with advanced lung, gastrointestinal, genitourinary, and breast cancer and their partners will be randomized to CCST or an education control intervention. Participants in both conditions complete self-reported outcome measures at baseline, mid-treatment, post-treatment, and 3 months post-treatment. Objective measures of communication are derived from video-recorded couple conversations collected at baseline and post-treatment. An implementation-related process evaluation (assessing implementation outcomes and potential barriers to/facilitators of implementation) will be conducted to inform future efforts to implement CCST in real-world settings. DISCUSSION: This trial can yield important new knowledge about effective ways to improve patient and partner adjustment to advanced cancer. TRIAL REGISTRATION: This study trial is registered at clinicaltrials.gov (Trial # NCT04590885); registration date: October 19, 2020.

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

Major depression is an episodic disorder which, for many individuals, has its onset in a distinct change of emotional state which then persists over time. The present article explores the utility of combining a dynamical systems approach to depression, focusing specifically on the change of state associated with episode onset, with a self-regulation perspective, which operationalizes how feedback received in the ongoing process of goal pursuit influences affect, motivation, and behavior, for understanding how a depressive episode begins. The goals of this review are to survey the recent literature modeling the onset of a depressive episode and to illustrate how a self-regulation perspective can provide a conceptual framework and testable hypotheses regarding episode onset within a dynamical systems model of depression.

RESUMO

A general psychopathology ('p') factor captures transdiagnostic features of mental illness; however, the meaning of the p factor remains unclear. Regulatory focus theory postulates that individuals regulate goal pursuit either by maximizing gains (promotion) or minimizing losses (prevention). As maladaptive goal pursuit has been associated with multiple categorical disorders, we examined whether individual differences in promotion and prevention goal pursuit are associated with p as well as internalizing- and externalizing-specific factors using structural equation modeling of data from 1330 volunteers aged 18-22. Unsuccessful attainment of promotion and prevention goals was related to increased levels of p. Over and above relations with the p factor, unsuccessful attainment of promotion goals was associated with higher internalizing-specific psychopathology, whereas unsuccessful attainment of prevention goals was related to higher externalizing-specific psychopathology. These associations also were separable from related personality traits. After controlling for sex differences in the composition of the psychopathology factors, there were no sex differences in the relations between promotion and prevention goal pursuit and p and specific internalizing and externalizing factors. These findings suggest higher general psychopathology reflects poorer overall self-regulation of goal pursuit and that maladaptive promotion and prevention orientations also are associated with internalizing- and externalizing-specific psychopathology, respectively.

RESUMO

Turner et al. (2021) subtly relapse in conceptualizing the Examination for Professional Practice in Psychology (Part 2-Skills) exam as a competency evaluation despite Association of State and Provincial Psychology Boards' (ASPPB) prior concession that Part 2 measures only the knowledge of skills (not skill competency). They do not address the purpose of redundant evaluation or the other concerns raised in Callahan et al. (2020). Instead, Turner et al. remain narrowly focused on defense of content validity and a reliance on outdated standards that fail to meet contemporary expectations for assessment of health care professionals. The adopted processes and procedures, albeit time consuming and effortful, are known to be methodologically inadequate. ASPPB's methods demonstrably foster linguistic biases and systemic racism that constricts licensure of diverse individuals as psychologists. Specific suggestions are offered, and ASPPB is urged to take drastic corrective action. (PsycInfo Database Record (c) 2021 APA, all rights reserved).

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

OBJECTIVE: Recent studies on atypical interoceptive capabilities have focused on clinical populations, including anorexia nervosa[1,2]. The present exploratory study aims to characterize the influence of disordered eating symptomology on interoceptive capabilities in college students, a population for which dangerous dieting behaviors may emerge. METHOD: Ninety-nine participants were randomized to consume a blinded high calorie or low calorie midday shake. Participants reported frequency of eating disorder cognitions and behaviors; indicated changes in satiety, happiness, and energy pre- and post-consumption; and guessed the calories in their shake. Outcomes (perceived satiety, changes in mood, and caloric guess) were regressed on eating disorder symptoms scores, the high/low calorie shake condition, and the interaction between these predictors. RESULTS: Those randomized to receive the high calorie shake reported feeling fuller, but only when endorsing lower levels of eating concern. Those randomized to the high calorie shake reported greater post-meal happiness, but only at greater levels of eating concerns. Lastly, those with lower levels of eating restraint reported an expected positive association between level of fullness and calorie guess, but those with higher levels of eating restraint did not exhibit any relationship between perceived fullness and calorie guess. DISCUSSION: Results of this exploratory suggest that irregular eating habits (e.g., not eating a sufficient amount for lunch) may have direct consequences on interoceptive capabilities. Further, these capacities may be impacted by individual differences in eating concern and restraint. Preliminary findings suggest that impairment in deciphering visceral signals may be associated with the degree of eating disorder symptomology; such impairment may occur at lower levels of symptomatology than normative data would indicate.

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

OBJECTIVE: Inadequate nutrition adversely impacts brain development and cognitive functioning (Pollitt et al., 1983). Studies examining the acute impact of eating regular meals on cognition have reported inconsistent findings, necessitating the exploration of individual differences in samples contributing to equivocal results. The present study examines the impact of skipping lunch on cognitive ability in college-aged students by including eating restraint as a moderator. METHODS: Participants were 99 college-aged students (M = 19.7 years, SD = 1.5) randomized to a blinded 'lunch' or 'lunch-omission' condition, and assessed on memory, attention, processing speed, set shifting, and eating disorder symptomology. RESULTS: Regressing long and short-term memory on the lunch manipulation, eating restraint scores, and their interaction revealed significant interactions: those who had lunch had superior memory performance, but only for those reporting lower levels of eating restraint. Regressing set shifting speed on the manipulation, those who had lunch had slower set shifting speed than those who skipped, but only for those reporting lower levels of eating restraint. CONCLUSIONS: Results suggest that skipping lunch may have immediate consequences on cognition, however, cognitive enhancing effects may be diminished in the presence of even low levels of eating restraint. Findings highlight the significance of purported subclinical levels of eating restraint and may inform health education strategies.

RESUMO

Regulatory focus theory (RFT) postulates two cognitive-motivational systems for personal goal pursuit: the promotion system, which is associated with ideal goals (an individual's hopes, dreams, and aspirations), and the prevention system, which is associated with ought goals (an individual's duties, responsibilities, and obligations). The two systems have been studied extensively in behavioral research with reference to differences between promotion and prevention goal pursuit as well as the consequences of perceived attainment versus nonattainment within each system. However, no study has examined the neural correlates of each combination of goal domain and goal attainment status. We used a rapid masked idiographic goal priming paradigm and functional magnetic resonance imaging to present individually selected promotion and prevention goals, which participants had reported previously that they were close to attaining ("match") or far from attaining ("mismatch"). Across the four priming conditions, significant activations were observed in bilateral insula (Brodmann area (BA) 13) and visual association cortex (BA 18/19). Promotion priming discriminantly engaged left prefrontal cortex (BA 9), whereas prevention priming discriminantly engaged right prefrontal cortex (BA 8/9). Activation in response to promotion goal priming was also correlated with an individual difference measure of perceived success in promotion goal attainment. Our findings extend the construct validity of RFT by showing that the two systems postulated by RFT, under conditions of both attainment and nonattainment, have shared and distinct neural correlates that interface logically with established network models of self-regulatory cognition.

RESUMO

Health disciplines have increasingly required competency-based evaluations as a licensure prerequisite. In keeping with this trend, the Association of State and Provincial Psychology Boards (ASPPB) has begun to develop a second part to the Examination for Professional Practice in Psychology (EPPP). The resulting 2-part examination is collectively referred to as the Enhanced EPPP. Part 1 of the Enhanced EPPP, which consists of the current exam, is designed to be an assessment of knowledge. Part 2 of the Enhanced EPPP is newly developed and intended to address the need for a competency-based evaluation. To date, ASPPB has addressed some standard facets of validity for the EPPP Part 2, but not others. In addition, the EPPP Part 2 has yet to be subjected to a broader validation process, in which the suitability of the test for its intended purpose is evaluated. Implementation of the EPPP Part 2 before validation could have negative consequences for those seeking to enter the profession and for the general public (e.g., potential restriction of diversity in the psychology workforce). For jurisdictions implementing the EPPP Part 2, failure to gather and report the evidence required for use of a test in a forensic context may also open the door for legal challenges. We end with suggestions for feasible research that could significantly enhance the validation process for the EPPP Part 2 and offer jurisdictions concrete suggestions of features to look for in determining whether and when to implement the Enhanced EPPP.

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

Self-discrepancy theory (SDT) is a model of the relations between the self and affect which has been applied to the study of different types of psychopathology including depression, anxiety, and eating disorders. Although the theory itself is compatible with a transdiagnostic perspective on psychopathology, to date no systematic review of the literature has examined that possibility. We conducted a meta-analysis that synthesized the literature on self-discrepancy and psychopathology across a heterogeneous range of 70 studies. Results showed a small-to-medium association between self-discrepancy and psychopathology that was highly robust and similar in magnitude across domains. Furthermore, self-discrepancy was related to higher levels of a range of negative emotions and lower levels of a range of positive emotions. Meta-regression models showed that the effects were greater for actual:ideal discrepancy compared with actual:ought discrepancy for both depression and anxiety, which was contrary to the tenets of SDT which suggests specific associations between actual:ideal discrepancy and depression and actual:ought discrepancy and anxiety. Measurement type (i.e., idiographic vs. nomothetic) was a significant predictor of the effects for depression and anxiety, such that nomothetic measures evidenced greater associations compared with idiographic measures. Our findings could suggest that self-discrepancy represents a contributory factor related to a number of psychiatric disorders. However, the tenet of SDT suggesting unique associations between actual:ideal and actual:ought discrepancy and anxiety and depression respectively was not supported. Implications are discussed for future research on self-discrepancy and psychopathology including the study of mechanistic frameworks. (PsycINFO Database Record (c) 2019 APA, all rights reserved).

RESUMO

Auto-biological beliefs-beliefs about one's own biology-are an understudied component of personal identity. Research participants who are led to believe they are biologically vulnerable to affective disorders report more symptoms and less ability to control their mood; however, little is known about the impact of self-originating beliefs about risk for psychopathology, and whether such beliefs correspond to empirically derived estimates of actual vulnerability. Participants in a neuroimaging study (n = 1256) completed self-report measures of affective symptoms, perceived stress, and neuroticism, and an emotional face processing task in the scanner designed to elicit threat responses from the amygdala. A subsample (n = 63) additionally rated their own perceived neural response to threat (i.e., amygdala activity) compared to peers. Self-ratings of neural threat response were uncorrelated with actual threat-related amygdala activity measured via BOLD fMRI. However, self-ratings predicted subjective distress across a variety of self-report measures. In contrast, in the full sample, threat-related amygdala activity was uncorrelated with self-report measures of affective distress. These findings suggest that beliefs about one's own biological threat response-while unrelated to measured neural activation-may be informative indicators of psychological functioning.
