Goal-Directed Treatment of Patients With Anxiety and Mood Disorders in a Regular Curative Mental Health Care Setting

This study examined whether goal-directed treatment leads to improved treatment outcomes for patients with a primary mood or anxiety disorder and whether beneficial outcomes are achieved sooner compared to treatment as usual. In a quasi-experimental controlled study with a nested design, 17 therapists received training in goal-directed treatment and treated 105 patients with anxiety or mood disorders using principles of goal-directed treatment. Treatment results on a generic self-report instrument were compared with two control groups: a historical control group consisting of 16 of the 17 participating therapists, who provided treatment as usual to 97 patients before having received training in goal-directed treatment, and a parallel control group consisting of various therapists, who provided treatment as usual to 105 patients. Symptom reduction on a self-report measure was compared using multilevel analysis. A survival analysis was performed to assess whether a satisfactory end state had been reached sooner after goal-directed treatment. The results of this study show that goal-directed treatment only led to a significantly better overall treatment outcome compared to the parallel treatment as usual group. Furthermore, goal-directed treatment was significantly shorter than both treatment as usual groups. In conclusion, this research suggest that goal-directed treatment led to a similar or better treatment outcome in a shorter amount of time.

Valenced dual tasking in patients with posttraumatic stress disorder

OBJECTIVE

Dual-tasking studies show that emotionality and vividness of aversive memory decrease by engaging in a working memory task and simultaneous recall of that memory. Adding positive valence to a dual task might be a promising innovation in the amelioration of lab-induced memory. However, studies aiming to translate these findings into autobiographical memory of a posttraumatic stress disorder (PTSD) population find conflicting results or show methodological flaws. The current study assesses the benefit of adding positive valence to a dual-tasking procedure in PTSD patients.

METHOD

In a cross-over design PTSD patients (N = 33) recalled their traumatic memory and received the following three conditions in randomized order: rating positive pictures + exposure, rating neutral pictures + exposure, and exposure only. Each of the three conditions consisted of four sets of 1 min. In the first cycle, participants were exposed to each condition in a randomized order, which was then repeated in a second cycle. Before and after each condition, emotionality and vividness were rated on a visual analog scale (VAS), resulting in seven measurement timepoints in total.

RESULTS

Firstly, repeated measures ANOVAs showed a time effect: memories were less emotional and vivid after our summed (three) interventions. Secondly, repeated measures ANCOVAs indicated no evidence for differences between the conditions.

CONCLUSIONS

We did not find evidence for a benefit of adding positive valence to a dual-task procedure in PTSD patients. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Cost-Effectiveness of Positive Memory Training (PoMeT) for the Treatment of Depression in Schizophrenia

The Positive Memory Training (PoMeT) trial demonstrated reduced depression symptoms at 3 months for schizophrenia, but its longer-term outcome and cost impacts remain unknown. This study is a within-trial cost-utility analysis with quality-adjusted life years (QALYs) as outcome based on health-related quality of life (HRQoL) measurement and secondary outcome analyses of capability well-being. The incremental cost-effectiveness of PoMeT was compared to Treatment As Usual only (TAU) over 9 months from the 'health and social' care and 'societal' perspectives. Uncertainty was explored using bootstrapping and sensitivity analyses for cost outliers and outcome methods. HRQoL improvement was observed for both PoMeT and TAU at 3 months, but reached statistical significance and was sustained only for TAU. There was no change in capability well-being and no significant group difference in QALYs gained over 9 months. Mean intervention cost was GBP 823. Compared to TAU, PoMeT had significantly higher mental health care costs (+GBP 1251, 95% CI GBP 185 to GBP 2316) during the trial, but 'health and social care' and 'societal' cost differences were non-significant. Compared to the before-trial period, psychiatric medication costs increased significantly in both groups. The probability of PoMeT being cost-effective in the given format over 9 months was <30% and decreased further in sensitivity analyses.. Generalizability remains limited since the before-after cost analysis revealed additional treatment effects also in the TAU group that likely diminished the incremental impacts and cost-effectiveness of PoMeT. It is not clear whether an active post-intervention follow-up could result in sustained longer-term effects and improved cost-effectiveness.

Game Design in Mental Health Care: Case Study-Based Framework for Integrating Game Design Into Therapeutic Content

While there has been increasing interest in the use of gamification in mental health care, there is a lack of design knowledge on how elements from games could be integrated into existing therapeutic treatment activities in a manner that is balanced and effective. To help address this issue, we propose a design process framework to support the development of mental health gamification. Based on the concept of experienced game versus therapy worlds, we highlight 4 different therapeutic components that could be gamified to increase user engagement. By means of a Dual-Loop model, designers can balance the therapeutic and game design components and design the core elements of a mental health care gamification. To support the proposed framework, 4 cases of game design in mental health care (eg, therapeutic protocols for addiction, anxiety, and low self-esteem) are presented.

Does valence contribute to the effects of dual tasking in aversive autobiographical memory? Some unexpected findings

BACKGROUND AND OBJECTIVES

Lab experiments show that engaging in a working memory task while recalling an aversive memory reduces emotionality and vividness of memories. Studies targeting lab induced negative memory with valenced secondary tasks show promise, but work is needed on autobiographical memories to make it more in line with the original dual tasking research and PTSD treatment in clinical populations. In this study, we address this gap by evaluating differential effectiveness of valenced dual tasks on emotionality and vividness of aversive autobiographical memories.

METHODS

University students (N = 178) recalled an aversive autobiographical memory while rating either positive pictures, negative pictures, or while looking at a cross in the exposure only condition. Participants were randomized to one of three aforementioned conditions and rated their memories before and after each intervention on emotionality and vividness.

RESULTS

Against expectations, memories became more emotional and vivid regardless of condition. With regard to vividness, this effect was characterized by an interaction effect: memories became more vivid in the exposure only condition than in the combined dual tasking conditions. All effect sizes were small.

LIMITATIONS

Working memory load in the dual tasking conditions might have been insufficient.

CONCLUSIONS

The current study did not extend findings with regard to (valenced) dual tasking and revealed a possible sensitization effect of script driven autobiographical memory induction. Our study highlights the importance of aspects such as the total amount of exposure and characteristics of memory induction, specifically the addition of a script driven approach to the usual self-initiated memory activation in dual tasking research.

Effectiveness of enhanced cognitive behavior therapy for eating disorders: A randomized controlled trial

OBJECTIVE

Enhanced cognitive behavior therapy (CBT-E) is a transdiagnostic treatment suitable for the full range of eating disorders (EDs). Although the effectiveness of CBT(-E) is clear, it is not being used as widely in clinical practice as guidelines recommend. The aim of the present study was to compare the effectiveness of CBT-E with treatment as usual (TAU), which was largely based on CBT principles.

METHOD

We conducted a randomized controlled trial on a total of 143 adult patients with an ED who received either CBT-E or TAU. The primary outcome was recovery from the ED. Secondary outcome measures were levels of ED psychopathology, anxiety, and depressive symptoms. Self-esteem, perfectionism, and interpersonal problems were repeatedly measured to examine possible moderating effects. We explored differences in duration and intensity between conditions.

RESULTS

After 80 weeks, there were no differences between conditions in decrease in ED psychopathology, or symptoms of anxiety and depression. However, in the first six weeks of treatment there was a larger decrease in ED psychopathology in the CBT-E condition. Moreover, when the internationally most widely used definition of recovery was applied, the recovery rate at 20 weeks of CBT-E was significantly higher (57.7%) than of TAU (36.0%). At 80 weeks, this difference was no longer significant (CBT-E 60.9%; TAU 43.6%). Furthermore, CBT-E was more effective in improving self-esteem and was also the less intensive and shorter treatment.

DISCUSSION

With broader use of CBT-E, the efficiency, accessibility and effectivity (on self-esteem) of treatment for EDs could be improved.

Linking Stressful Experiences and Psychological Problems: The Role of Self-Esteem

Stressful experiences have repeatedly been related to psychological problems. The current study extends previous work on stress and psychological problems by examining the link between stressful experiences and both internalizing (INT) and externalizing (EXT) problems. Additionally, individual differences are investigated by testing the moderating role of self-esteem. Questionnaire data of 750 adolescents aged 12–18 were collected and analyzed using multiple regression analyses. Analyses were controlled for sex and socioeconomic status. Results indicated that adolescents who report more stressful experiences are more likely to experience both INT and EXT problems, and these relationships were stronger for adolescents with low self-esteem. Post hoc analyses (e.g., different thresholds for determining stressful experiences) support the robustness of our findings. The findings on self-esteem emphasize the importance of taking individual differences into account in the relation between stressful experiences and psychological problems. The results can be seen as a next step in cross-sectional research.

Effectiveness of enhanced cognitive behavioral therapy (CBT-E) for eating disorders: study protocol for a randomized controlled trial

BACKGROUND

While eating disorder not otherwise specified (EDNOS) is the most common eating disorder (ED) diagnosis in routine clinical practice, no specific treatment methods for this diagnosis have yet been developed and studied. Enhanced cognitive behavioral therapy (CBT-E) has been described and put to the test as a transdiagnostic treatment protocol for all EDs, including EDNOS. Initial research in the UK suggests that CBT-E is more effective for EDs, especially bulimia nervosa (BN) and EDNOS, than the earlier version of CBT. These positive results of CBT-E have to be replicated in more detail, preferably by independent researchers in different countries. Being the first Dutch study into CBT-E, the results from this national multicenter study - on three sites specialized in EDs - will deliver important information about the effectiveness of CBT-E in several domains of ED pathology, while providing input for the upcoming update of the Dutch Multidisciplinary Guideline for the Treatment of Eating Disorders.

METHODS/DESIGN

A multicenter randomized controlled trial will be conducted. One hundred and thirty-two adult outpatients (aged 18 years and older) with an ED diagnosis and a Body Mass index (BMI) of between 17.5 and 40 will be randomly allocated to the control or the intervention group. Subjects in the control group will receive Treatment as Usual (standard outpatient treatment provided at the participating sites). Subjects in the intervention group will receive 20 sessions of CBT-E in 20 weeks. The design is a 2 (group) × 5 (time) repeated measures factorial design in which neither therapists nor patients will be blinded for treatment allocation. The primary outcome measure is recovery from the ED. Secondary outcome measures include ED psychopathology, common mental disorders, anxiety and depressive symptoms, health-related quality of life, health care use and productivity loss. Self-esteem, perfectionism and interpersonal problems will be examined as putative predictors and mediators of the effect of treatment. Also, an economic evaluation from a societal perspective will be undertaken. All relevant effects, direct and indirect costs will be included. Utility scores will measure the effects. Measurements will take place at pretreatment, 6 weeks, 20 weeks, 40 weeks and 80 weeks.

DISCUSSION

This effectiveness study into CBT-E has the aim of broadening the scope and generalizability of former studies. If CBT-E appears to be at least as effective as traditional diagnosis-specific treatments for a broad range of ED patients, training in one protocol would be sufficient for clinicians to treat patients with different kinds of EDs. It gives the opportunity to offer treatment for a severe mental disorder with fewer resources, thereby increasing the accessibility of specialized care for patients with an ED.

A randomised controlled trial of positive memory training for the treatment of depression within schizophrenia

BACKGROUND

Depression is highly prevalent within individuals diagnosed with schizophrenia, and is associated with an increased risk of suicide. There are no current evidence based treatments for low mood within this group. The specific targeting of co-morbid conditions within complex mental health problems lends itself to the development of short-term structured interventions which are relatively easy to disseminate within health services. A brief cognitive intervention based on a competitive memory theory of depression, is being evaluated in terms of its effectiveness in reducing depression within this group.

METHODS/DESIGN

This is a single blind, intention-to-treat, multi-site, randomized controlled trial comparing Positive Memory Training plus Treatment as Usual with Treatment as Usual alone. Participants will be recruited from two NHS Trusts in Southern England. In order to be eligible, participants must have a DSM-V diagnosis of schizophrenia or schizo-affective disorder and exhibit at least a mild level of depression. Following baseline assessment eligible participants will be randomly allocated to either the Positive Memory Training plus Treatment as Usual group or the Treatment as Usual group. Outcome will be assessed at the end of treatment (3-months) and at 6-month and 9-month post randomization by assessors blind to group allocation. The primary outcome will be levels of depression and secondary outcomes will be severity of psychotic symptoms and cost-effectiveness. Semi-structured interviews will be conducted with all participants who are allocated to the treatment group so as to explore the acceptability of the intervention.

DISCUSSION

Cognitive behaviour therapy is recommended for individuals diagnosed with schizophrenia. However, the number of sessions and length of training required to deliver this intervention has caused a limit in availability. The current trial will evaluate a short-term structured protocol which targets a co-morbid condition often considered of primary importance by service users. If successful the intervention will be an important addition to current initiatives aimed at increasing access to psychological therapies for people diagnosed with severe mental health problems.

A Dutch version of the Overall Anxiety Severity and Impairment Scale (OASIS): Psychometric properties and validation

BACKGROUND

The Overall Anxiety Severity and Impairment Scale (OASIS) is a 5-item self-report measure that can be used to assess the impact of any anxiety disorder or multiple anxiety disorders. Prior US investigations have shown the OASIS to be a reliable and valid measure. To date the OASIS has not been validated for use in a Dutch sample of anxiety disordered patients.

METHODS

The present study assessed the psychometric properties of a Dutch version of the OASIS in a clinical sample of anxiety patients. Latent structure, internal consistency, convergent and discriminant validity, and cutoff score analyses were conducted. Results were compared to those obtained from a clinical sample of patients with psychiatric diagnoses other than anxiety disorders.

RESULTS

Principal component analysis supported a unidimensional structure. The five OASIS items loaded strongly on a single factor (eigenvalue=3.682, loadings=.80-.89) which accounted for 73.65% of the variance, and had a high degree of internal consistency (Cronbach׳s α=91). OASIS scores demonstrated robust correlations with other measures of anxiety, neuroticism and general distress. Correlations with unrelated constructs were weak. Mean score (8.46) and cutoff score of the Dutch sample of anxiety patients were lower than scores previously found in American samples. A cutoff score of 5 correctly classified 82.5% of this sample as having an anxiety disorder diagnosis or not. An improvement of 4 points is indicative of a clinically significant change.

LIMITATIONS

This study mainly relied on self-report measures in order to assess validity. Other types of measures should be used in future studies.

CONCLUSIONS

The Dutch version of the OASIS showed good reliability and validity. Its brevity and sound psychometric properties make it a good instrument for screening and assessment purposes in the field of anxiety disorders.

Competitive memory training (COMET) for treating low self-esteem in patients with depressive disorders: a randomized clinical trial

BACKGROUND

Self-esteem is a major concern in mood disorders. Low self-esteem is a symptom of depressive disorders and is considered by some to be a predictor for relapse, whereas high self-esteem seems to buffer against depression. Recently, Competitive Memory Training (COMET) has shown to be effective for the enhancement of self-esteem in several psychopathological conditions. The current study assesses whether COMET is also an effective intervention for patients with depressive disorders.

METHODS

Sixty-one patients with depressive disorders who were already in therapy in an outpatient mental health institution were randomly assigned to either eight group sessions of COMET in addition to their regular therapy (COMET + therapy as usual [TAU]: the experimental group) or to 8 weeks of ongoing regular therapy (TAU only: the control group). These latter (control) patients received COMET after their TAU only period. All patients in both groups that completed COMET were contacted 3 and 6 months later to assess whether the effects of COMET had remained stable.

RESULTS

Compared to the patients who received TAU only, patients in the COMET + TAU condition showed significant improvement with large effect sizes on indices of self-esteem, depression, and depressive rumination. The therapeutic effects of COMET + TAU remained stable after 3 and 6 months on all outcome measures or improved even further.

CONCLUSION

COMET for low self-esteem seems to be an efficacious trans-diagnostic intervention that can relatively easily be added to the regular treatment of patients with depressive disorders.

Initial evaluation of the effects of competitive memory training (COMET) on depression in schizophrenia-spectrum patients with persistent auditory verbal hallucinations: a randomized controlled trial

OBJECTIVES

This study investigates whether depression can be ameliorated by weakening the associations between auditory verbal hallucinations and easily activated networks with negative self-evaluations, by strengthening the access to competing memories of positive self-esteem. Design.  A randomized controlled clinical trial comparing competitive memory training (COMET) with treatment as usual (TAU) in schizophrenia patients with persistent auditory hallucinations.

METHODS

Patients with schizophrenia-spectrum disorders were randomized into COMET (n = 39) versus TAU (n = 38). COMET consisted of seven sessions with four stages: (1) identification of aspects of negative self-esteem reinforced by the voice; (2) retrieval and re-living of memories associated with positive self-esteem; (3) positive self-esteem is brought in to compete with the content of the voices to weaken the association between voice content and negative self-evaluation; and (4) learning to disengage from the voices and to accept the voices as psychic phenomena.

RESULTS

Compared to TAU the COMET group improved on depression but there were no significant effects on auditory hallucinations. The effect of COMET on depression was fully mediated by self-esteem and acceptance of voices, and partially mediated by social rank and attributed power to the voices.

CONCLUSIONS

COMET can be helpful in reappraising the meaning and changing the emotional impact of auditory hallucinations. These findings are consistent with the results of comparable COMET protocols applied in other psychiatric diagnoses. The technique can be used within regular cognitive behavioural therapy.
