Binge-eating adolescent treatment (BEAT) - findings from a pilot study on effects and acceptance of a blended treatment program for youth with loss of control eating

BACKGROUND

Loss of Control Eating (LOC) is the most prevalent form of eating disorder pathology in youth, but research on evidence-based treatment in this group remains scarce. We assessed for the first time the effects and acceptance of a blended treatment program for youth between 14 and 24 years with LOC (Binge-eating Adolescent Treatment, BEAT).

METHODS

Twenty-four youths (mean age 19.1 years) participated in an active treatment of nine-weeks including three face-to-face workshops and six weekly email-guided self-help sessions, followed by four email guided follow-up sessions, one, three, six and 12 months after the active treatment. All patients completed a two-weeks waiting-time period before treatment begin (within-subject waitlist control design).

RESULTS

The number of weekly LOC episodes substantially decreased during both the waiting-time (effect size d = 0.45) and the active treatment (d = 1.01) period and remained stable during the subsequent 12-months follow-up (d = 0.20). The proportion of patients with full-threshold binge-eating disorder (BED) diagnoses decreased and transformed into LOC during the study course, while the abstainer rate of LOC increased. Values for depressive symptoms (d = 1.5), eating disorder pathology (d = 1.29) and appearance-based rejection sensitivity (d = 0.68) all improved on average from pretreatment to posttreatment and remained stable or further improved during follow-up (d between 0.11 and 0.85). Body weight in contrast remained constant within the same period. Treatment satisfaction among completers was high, but so was the dropout rate of 45.8% at the end of the 12-months follow-up.

CONCLUSIONS

This first blended treatment study BEAT might be well suited to decrease core symptoms of LOC, depressive symptoms and appearance-based rejection sensitivity. More research is needed to establish readily accessible interventions targeted more profoundly at age-salient maintaining factors such as appearance-based rejection sensitivity, while at the same time keeping dropout rates at a low level.

TRIAL REGISTRATION

The trial was registered at the German Clinical Trials Register (ID: DRKS00014580; registration date: 21/06/2018).

Exploring the path of persisting dysfunctional expectations-Development of the immunization scale IMS

Objectives

Persistent dysfunctional expectations seem to be core features of mental disorders. The aim of this study was to develop a questionnaire that assesses mechanisms responsible for the consistency of dysfunctional expectations. Processes before (i.e., assimilation) and after (i.e., immunization) expectation-violating experiences have been considered.

Design

The Immunization Scale (IMS) is constructed and validated with the help of an explorative (EFA) and confirmatory factor analysis (CFA) in two conducted studies.

Materials and methods

For the first study, the initially formulated 75-item version was completed online by 230 (range 18-69) participants from a convenience sample. For the second study, 299 (range 18-62) participants completed the reduced scale at the first measurement point, 75 participants thereof also 1 month later. For validity and reliability analyses, participants in both studies provided demographic information, the Beck Depression Inventory (BDI-II), the Depressive Expectation Scale (DES), the Beck Anxiety Inventory (BAI), and the German version of the Acceptance and Action Questionnaire (FAH-II).

Results

The initial 75 items were reduced to 23 items. The EFA revealed three main factors, namely, negative expectations, assimilation, and cognitive immunization. The three-factor structure could be confirmed in study 2 by the CFA. Reliability measures showed an excellent internal consistency for the entire IMS. A very good test-retest reliability was found. Significant correlations resulted between the IMS and DES, BDI-II, BAI, and FAH-II, the highest for DES and FAH-II.

Conclusion

Psychometric properties of the IMS are promising. Future studies should verify the reliability and validity measures in other population samples. The IMS can be very useful in expectation research, especially in the examination of expectation-focused therapy.

The reasons for its effectiveness, however, remain in dispute—A tribute to Irving Kirsch

Irving Kirsch’s work spans over four decades and provided science and clinical practice with as much invaluable insights in the inner workings of treatments as it provided us and patients with their rights and our duties. Here, two early publications of Irving Kirsch on the topic of psychotherapy and its relation to placebo are revised and put into both a historical and contemporary context to pay tribute to the work of Irving Kirsch.

Psychedelics, placebo effects, and set and setting: Insights from common factors theory of psychotherapy

Psychedelic-assisted treatment is at first glance markedly different in structure and approach from mainstream forms of psychotherapy in the West. A major criticism of clinical psychedelic research rests on the difficulty of executing placebo-controlled studies and distinguishing drug effects from those of the psychotherapeutic container in which psychedelics are typically presented. Detractors also tend to find fault in spiritual or mystical themes that often arise in the context of psychedelic use. Common factors theory of psychotherapy is a useful and extensively studied framework that can help make sense of these issues, and has much to contribute to our understanding of contextual effects that are often discussed in psychedelic literature as "set and setting." In this article, we examine four major contextual "common factors" shared by various healing traditions: 1) the therapeutic relationship; 2) the healing setting; 3) the rationale, conceptual scheme, or myth; and 4) the ritual. We explain how these factors show up in psychedelic-assisted treatment and how they may contribute to therapeutic effects. Lastly, we discuss the implications of these factors for the concept of placebo, and for future research.

Healing in a Social Context: The Importance of Clinician and Patient Relationship

When a patient presents to a health provider, the course of the disorder is composed of three effects: natural effects, specific effects, and contextual effects. Part of the contextual effect is due to the relationship between the healer and the patient. Social healing appears to be present in eusocial species and particularly well-developed in humans. Evidence for the importance of the relationship in healing is found in placebo studies, including placebo analgesics, medicine, and psychotherapy. Although the theory for how the relationship is therapeutic is not well-developed, four possible mechanisms are discussed. The implications for health care and the treatment of pain are discussed.

Placebo From an Enactive Perspective

Due to their complexity and variability, placebo effects remain controversial. We suggest this is also due to a set of problematic assumptions (dualism, reductionism, individualism, passivity). We critically assess current explanations and empirical evidence and propose an alternative theoretical framework—the enactive approach to life and mind—based on recent developments in embodied cognitive science. We review core enactive concepts such as autonomy, agency, and sense-making. Following these ideas, we propose a move from binary distinctions (e.g., conscious vs. non-conscious) to the more workable categories of reflective and pre-reflective activity. We introduce an ontology of individuation, following the work of Gilbert Simondon, that allow us to see placebo interventions not as originating causal chains, but as modulators and triggers in the regulation of tensions between ongoing embodied and interpersonal processes. We describe these interrelated processes involving looping effects through three intertwined dimensions of embodiment: organic, sensorimotor, and intersubjective. Finally, we defend the need to investigate therapeutic interactions in terms of participatory sense-making, going beyond the identification of individual social traits (e.g., empathy, trust) that contribute to placebo effects. We discuss resonances and differences between the enactive proposal, popular explanations such as expectations and conditioning, and other approaches based on meaning responses and phenomenological/ecological ideas.

Blinding in randomised clinical trials of psychological interventions: a retrospective study of published trial reports

OBJECTIVES

To study the extent of blinding in randomised clinical trials of psychological interventions and the interpretative considerations if randomised clinical trials are not blinded.

DESIGN

Retrospective study of trial reports published in six high impact factor journals within the field of psychiatry in 2017 and 2018.

SETTING

Trial reports published in World Psychiatry, JAMA Psychiatry, Lancet Psychiatry, American Journal of Psychiatry, British Journal of Psychiatry, or Psychotherapy and Psychosomatics.

MAIN OUTCOME MEASURES

Blinding status of participants, treatment providers, outcome assessors, data managers, the data safety and monitoring committee, statisticians and conclusion makers, if trialists rejected the null hypothesis on the primary outcome measure, and if trialists discussed the potential bias risk from lack of blinding in the published trial report.

RESULTS

63 randomised clinical trials of psychological interventions were identified. None (0%; 95% CI 0% to 5.75%) of the trials reported blinding of all possible key persons. 37 (58.7%; 95% CI 46.42% to 70.04%) trials reported blinding of outcome assessors. Two (3.2%; 95% CI 0.87% to 10.86%) trials reported blinding of participants. Two (3.2%; 95% CI 0.87% to 10.86%) trials reported blinding of data managers. Three (4.8%; 95% CI 1.63% to 13.09%) trials reported blinding of statisticians. None of the trials reported blinding of treatment providers, the data safety and monitoring committee, and conclusion makers. 45 (71.4%; 95% CI 59.30% to 81.10%) trials rejected the null hypothesis on the primary outcome(s). 13 (20.7%; 95% CI 12.48% to 32.17%) trials discussed the potential bias risk from lack of blinding in the published trial report.

CONCLUSIONS

Blinding of key persons involved in randomised clinical trials of psychological interventions is rarely sufficiently documented. The possible interpretative limitations are only rarely considered. There is a need of randomised clinical trials of psychological interventions with documented blinding attempts of all possible key persons.

Talking to Children and Families about Chronic Pain: The Importance of Pain Education-An Introduction for Pediatricians and Other Health Care Providers

Chronic pain in children and adolescents is a common and debilitating health problem. This narrative review will give a brief overview on what pediatric chronic pain is and what treatment options there are for children and adolescents. The specific emphasis will be on pediatric chronic pain education and communication: this narrative review aims to show how important a good patient-health care provider relationship is-it builds the foundation for successful communication-and how this relationship can be established. In addition, we will present five steps that health care providers can perform to explain pediatric chronic pain to patients and their parents and what to keep in mind in their clinical routine. Our review is intended for pediatricians and other health care providers who treat pediatric patients with chronic pain but might feel uncertain on how to best communicate with them.

Effects of Prehypnotic Instructions on Hypnotizability and Relationships Between Hypnotizability, Absorption, and Empathy

Although hypnotizability exhibits high across-time and across-test consistencies, it is not clear (a) how different preambles to a hypnotic procedure (metasuggestions) influence responsiveness to suggestions and the strength of the association between two hypnotizability scales and (b) how hypnotizability relates to absorption and empathy. In Experiment 1, nonclinical participants (N = 152 women) were administered the Modified Tellegen Absorption Scale (MODTAS), Interpersonal Reactivity Index (IRI), Hypnotic Induction Profile (HIP), and Stanford Hypnotic Susceptibility Scale, Form C (SHSS:C). In Experiment 2, nonclinical participants (N = 188; 105 women and 83 men) were administered the MODTAS, IRI, and Harvard Group Scale of Hypnotic Susceptibility, Form A (HGSHS:A). The induction scores of the HIP (HIP-IND) and the SHSS:C scores showed a significantly stronger correlation when the HIP was introduced to the participants after hypnosis metasuggestion (HIP-H-IND) than after imagination metasuggestion (HIP-I-IND). Metasuggestion was a moderator of the association between HIP-IND and SHSS:C scores. Participants with low and medium, but not with high, hypnotizability levels on the SHSS:C showed significantly higher scores on the HIP-I-IND than on the HIP-H-IND. The strong correlations between the SHSS:C, HIP-H-IND, and HIP eye-roll (HIP-ER) scores indicate that both the HIP-H-IND and HIP-ER are robust measures of hypnotizability. Absorption and empathy were not significantly associated with hypnotizability. Women were more hypnotizable than men, as assessed by the HGSHS:A. The clinical relevance of metasuggestions, intended to increase responsiveness to suggestions, is discussed as a strategy to improve treatment outcomes.

Attitudes About Informed Consent: An Exploratory Qualitative Analysis of UK Psychotherapy Trainees

Background: Ethical informed consent to psychotherapy has recently been the subject of in-depth analysis among healthcare ethicists. Objective: This study aimed to explore counseling and psychotherapy students' views and understanding about informed consent to psychological treatments. Methods: Two focus groups were conducted with a total of 10 students enrolled in a Masters course in counseling and psychotherapy at a British university. Questions concerned participants' understanding of informed consent including judgments about client capacity; the kinds of information that should be disclosed; how consent might be obtained; and their experiences of informed consent, both as a client and as a therapist. Focus groups were audio-recorded, transcribed, and analyzed using qualitative content analysis. Coding was conducted independently by three authors. Results: Comments were classified into three main themes: (1) the reasons and justifications for informed consent; (2) informed consent processes; and (3) the hidden ethics curriculum. Some trainees expressed significant doubts about the importance of informed consent. However, participants also identified the need to establish the clients' voluntariness and their right to be informed about confidentiality issues. In general, the format and processes pertaining to informed consent raised considerable questions and uncertainties. Participants were unsure about rules surrounding client capacity; expressed misgivings about describing treatment techniques; and strikingly, most trainees were skeptical about the clinical relevance of the evidence-base in psychotherapy. Finally, trainees' experiences as clients within obligatory psychotherapy sessions were suggestive of a "hidden ethics curriculum"-referring to the unintended transmission of norms and practices within training that undermine the explicit guidance expressed in formal professional ethics codes. Some students felt coerced into therapy, and some reported not undergoing informed consent processes. Reflecting on work placements, trainees expressed mixed views, with some unclear about who was responsible for informed consent. Conclusions: This qualitative study presents timely information on psychotherapy students' views about informed consent to psychotherapy. Major gaps in students' ethical, conceptual, and procedural knowledge were identified, and comments suggested the influence of a hidden curriculum in shaping norms of practice. Implications: This exploratory study raises important questions about the preparedness of psychotherapy students to fulfill their ethical obligations.

Psychotherapy: A World of Meanings

Despite a wealth of findings that psychotherapy is an effective psychological intervention, the principal mechanisms of psychotherapy change are still in debate. It has been suggested that all forms of psychotherapy provide a context which enables clients to transform the meaning of their experiences and symptoms in such a way as to help clients feel better, and function more adaptively. However, psychotherapy is not the only health care intervention that has been associated with "meaning": the reason why placebo has effects has also been proposed to be a "meaning response." Thus, it has been argued that the meaning of treatments has a central impact on beneficial (and by extension, negative) health-related responses. In light of the strong empirical support of a contextual understanding of psychotherapy and its effects, the aim of this conceptual analysis is to examine the role of meaning and its transformation in psychotherapy-in general-and within three different, commonly used psychotherapy modalities.

Effects of an epilepsy-specific Internet intervention (Emyna) on depression: Results of the ENCODE randomized controlled trial

OBJECTIVE

Depression and anxiety are highly prevalent among people with epilepsy (PwE) but often remain unrecognized and treated inadequately. Effective psychosocial treatments such as cognitive behavioral therapy (CBT) are rarely available to most PwE, which is one reason electronically delivered CBT (eCBT) is regarded as promising. This study examined an eCBT intervention, termed Emyna, that was tailored to suit the needs of PwE. It includes CBT-related content on depression, stress and anxiety, seizure triggers and auras, and lifestyle habits. The trial examined the efficacy of Emyna in reducing symptoms of depression (primary outcome) and anxiety as well as improving quality of life.

METHODS

Participants (N = 200) with epilepsy, a diagnosis of a depressive disorder, and at least moderate depressive symptoms were randomized to Emyna or care as usual. At baseline and after 3, 6, and 9 months, participants were invited to complete online questionnaires. The primary outcome was improvement of depressive symptoms at 3 months.

RESULTS

Relative to the control group, intervention group participants experienced significantly greater improvements in depression, anxiety, stress, social-occupational impairment, and epilepsy-related quality of life, in both intention-to-treat (ITT) and per-protocol analyses. In ITT analyses, effects of medium magnitude were observed, as measured by the Patient Health Questionnaire-9 items (Cohen d = 0.54, 95% confidence interval [CI] = 0.25-0.82, P < 0.001) and the Neurological Disorders Depression Inventory for Epilepsy (d = 0.51, 95% CI = 0.23-0.79, P < 0.01). At 3 months, intervention group participants also reported fewer illness-related days off work and fewer days hospitalized over the preceding months, compared to control group participants (P ≤ 0.05), whereas no such differences were present at baseline (P > 0.30).

SIGNIFICANCE

These findings showed that Emyna, used adjunctively to usual care, could help improve mental health, social-occupational functioning, and quality of life among PwE. The program provides an additional treatment option that could produce clinically relevant symptom reductions and reduce key cost drivers (ie, hospitalization rates and illness-related inability to work).

The Effectiveness of an Internet Intervention Aimed at Reducing Alcohol Consumption in Adults

BACKGROUND

In 2012, approximately 3.38 million people in Germany had an alcoholrelated disorder. Internet interventions can help lower alcohol consumption, albeit with mostly small effect sizes. It is still unclear whether the effectiveness of programs aimed at lowering alcohol consumption can be improved by individually adjusting program content for each participant. We studied the effectiveness of Vorvida, a new cognitive-behavioral internet intervention with individual adjustment of content.

METHODS

A randomized controlled trial was conducted on 608 adults with problematic alcohol consumption. The primary outcome was self-reported alcohol con - sumption in the past 30 days (as determined by the Quantity-Frequency-Index, QFI) and in the past 7 days (using the Timeline Follow-Back method, TFB). The secondary outcomes were drinking behavior (binge drinking/drunkenness) and satisfaction with Vorvida. Data were collected at three time points: at baseline (t0) and three and six months later (t1, t2). Trial registration: DRKS00006104.

RESULTS

The intention-to-treat (ITT) analysis revealed significant differences between groups at time t1 with respect to alcohol consumption (QFI: d = 0.28; TFB: d = 0.42), binge drinking (d = 0.87), and drunkenness (d = 0.39). Satisfaction with the intervention was high (27.4 [standard deviation, SD: 5.3] out of 32 points). All effects persisted, or were stronger, at time t2. Alcohol consumption, as measured by the QFI, declined over the interval from t0 to t2 in both groups: from 63.69 g/day (SD: 61.4) to 32.67 g/day (SD: 39.78) in the intervention group, and from 61.64 g/day (SD: 58.84) to 43.75 g/day (SD: 43.68) in the control group.

CONCLUSION

Vorvida was found to be effective in persons with risky, problematic alcohol consumption. Further studies should determine which elements of the program contribute most to effectiveness in routine clinical practice, and what long-term effects can be achieved.

Placebo Effects in Psychotherapy: A Framework

The issue of placebo response and the extent of its effect on psychotherapy is complex for two specific reasons: i) Current standards for drug trials, e.g., true placebo interventions, double-blinding, cannot be applied to most psychotherapy techniques, and ii) some of the "nonspecific effects" in drug therapy have very specific effects in psychotherapy, such as the frequency and intensity of patient-therapist interaction. In addition, different psychotherapy approaches share many such specific effects (the "dodo bird verdict") and lack specificity with respect to therapy outcome. Here, we discuss the placebo effect in psychotherapy under four aspects: a) nonspecific factors shared with drug therapy (context factors); b) nonspecific factors shared among all psychotherapy traditions (common factors); c) specific placebo-controlled options with different psychotherapy modalities; and d) nonspecific control options for the specific placebo effect in psychotherapy. The resulting framework proposes that the exploration and enumeration of context factors, common factors, and specific factors contributes to the placebo effects in psychotherapy.

Inclusion and exclusion strategies for conducting meta-analyses

Some of the most important decisions that a researcher will make when conducting a meta-analysis are decisions about the search strategies and inclusion/exclusion criteria. Decisions regarding inclusion/exclusion criteria serve to define the scope of a meta-analysis and search strategy decisions can have a large impact on how well the results of a meta-analysis actually represent the existing body of literature. In this article, we provide descriptions and recommendations for performing searches and making inclusion/exclusion decisions. We also provide a review of 65 meta-analyses of psychotherapy versus pharmacotherapy in order to offer frequency data on the use of various search strategies and inclusion/exclusion decisions in the field.
