The effect of age on emotion processing in individuals with mood disorders and in healthy individuals.

Introduction: Emotion processing is an essential part of interpersonal relationships and social interactions. Changes in emotion processing have been found in both mood disorders and in aging, however, the interaction between such factors has yet to be examined in detail. This is of interest due to the contrary nature of the changes observed in existing research - a negativity bias in mood disorders versus a positivity effect with aging. It is also unclear how changes in non-emotional cognitive function with aging and in mood disorders, interact with these biases. Methods and results: In individuals with mood disorders and in healthy control participants, we examined emotional processing and its relationship to age in detail. Data sets from two studies examining facial expression recognition were pooled. In one study, 98 currently depressed individuals (either unipolar or bipolar) were compared with 61 healthy control participants, and in the other, 100 people with bipolar disorder (in various mood states) were tested on the same facial expression recognition task. Repeated measures analysis of variance was used to examine the effects of age and mood disorder diagnosis alongside interactions between individual emotion, age, and mood disorder diagnosis. A positivity effect was associated with increasing age which was evident irrespective of the presence of mood disorder or current mood episode. Discussion: Results suggest a positivity effect occurring at a relatively early age but with no evidence of a bias toward negative emotions in mood disorder or specifically, in depressed episodes. The positivity effect in emotional processing in aging appears to occur even within people with mood disorders. Further research is needed to understand how this fits with negative biases seen in previous studies in mood disorders.

Clinical factors and early life experiences associated with therapeutic alliance development in treatment for depression or binge eating.

OBJECTIVE: This study examines childhood and clinical factors theorized to impact therapeutic alliance development over the course of psychotherapy. METHOD: Raters assessed the therapeutic alliance of 212 client-therapist dyads, participating in two randomized controlled trials of schema therapy and cognitive behavioural therapy for binge eating or major depression, at three time points. Linear mixed models were used to characterize therapeutic alliance development over time and assess the influence of childhood trauma, perceived parental bonding, diagnosis and therapy type on scores. RESULTS: Participants differed in initial alliance ratings for all subscales but had similar growth trajectories in all but the patient hostility subscale. A diagnosis of bulimia nervosa or binge eating disorder predicted greater initial levels of client distress, client dependency and overall client contribution to a strong therapeutic alliance, compared with a diagnosis of depression. Therapy type, childhood trauma and perceived parental bonds did not predict alliance scores. CONCLUSION: Findings highlight the potential influence of clinical and personal characteristics on alliance strength and development, with implications for maximizing treatment outcomes through anticipating and responding to these challenges.

Examining the long-term cognitive effects of exposure to the Canterbury earthquakes in a resilient cohort.

BACKGROUND: Although most people do not develop mental health disorders after exposure to traumatic events, they may experience subtle changes in cognitive functioning. We previously reported that 2-3 years after the Canterbury earthquake sequence, a group of trauma-exposed people, who identified as resilient, performed less well on tests of spatial memory, had increased accuracy identifying facial emotions and misclassified neutral facial expressions to threat-related emotions, compared with non-exposed controls. AIMS: The current study aimed to examine the long-term cognitive effects of exposure to the earthquakes in this resilient group, compared with a matched non-exposed control group. METHOD: At 8-9 years after the Canterbury earthquake sequence, 57 earthquake-exposed resilient (69% female, mean age 56.8 years) and 60 non-exposed individuals (63% female, mean age 55.7 years) completed a cognitive testing battery that assessed verbal and visuospatial learning and memory, executive functioning, psychomotor speed, sustained attention and social cognition. RESULTS: With the exception of a measure of working memory (Digit Span Forward), no significant differences were found in performance between the earthquake-exposed resilient and non-exposed groups on the cognitive tasks. Examination of changes in cognitive functioning over time in a subset (55%) of the original earthquake-exposed resilient group found improvement in visuospatial performance and slowing of reaction times to negative emotions. CONCLUSIONS: These findings offer preliminary evidence to suggest that changes in cognitive functioning and emotion processing in earthquake-exposed resilient people may be state-dependent and related to exposure to continued threat in the environment, which improves when the threat resolves.

An exploratory examination of executive functioning as an outcome, moderator, and predictor in outpatient treatment for adults with anorexia nervosa.

OBJECTIVE: People with anorexia nervosa often exhibit inefficiencies in executive functioning (central coherence and set shifting) that may negatively impact on treatment outcomes. It is unclear from previous research whether these inefficiencies can change over treatment. We aimed to (1) investigate whether executive functioning can improve over treatment, (2) determine whether baseline executive functioning moderates treatment outcome, and (3) examine whether baseline executive functioning predicts early change (i.e., increase in body mass index over the first 13 weeks of treatment) or remission. METHOD: We conducted linear mixed model and logistic regression analyses on data from the Strong Without Anorexia Nervosa trial (Byrne et al. in Psychol Med 47:2823-2833, 2017). This study was a randomised controlled trial of three outpatient treatments for people with anorexia nervosa: Enhanced Cognitive Behavioural Therapy, Maudsley Model Anorexia Nervosa Treatment for Adults, and Specialist Supportive Clinical Management. RESULTS: While set shifting clearly improved from baseline to end of treatment, the results for central coherence were less clear cut. People with low baseline central coherence had more rapid reductions in eating disorder psychopathology and clinical impairment than those with high baseline central coherence. Baseline executive functioning did not predict early change or remission. DISCUSSION: The detail-focused thinking style commonly observed among people with anorexia nervosa may aid treatment outcomes. Future research that is more adequately powered should replicate this study and examine whether the same pattern of results is observed among people with non-underweight eating disorders.

People with anorexia nervosa often have difficulty thinking flexibly and in terms of the big picture. We investigated whether these thinking styles (1) change over treatment, (2) influence response to treatment, or (3) predict whether people gain weight or overcome the eating disorder. We found that people were able to think more flexibly after treatment. We also found that people who had more difficulty seeing the big picture prior to treatment had a more rapid decrease in eating disorder symptoms and clinical impairment in treatment. Thinking styles did not predict whether people gained weight early in treatment or overcame the eating disorder. Our findings suggest that the detail-focused thinking style commonly observed among people with anorexia nervosa can be both a vulnerability and a strength.

The effect of temperament and character on body dissatisfaction in women with bulimia nervosa: The role of low self-esteem and depression.

OBJECTIVE: Although personality traits have been found to be associated with body dissatisfaction for women in the general population, little research has explored these associations for people with eating disorders. Furthermore, it is unknown whether these associations are direct or are mediated by other factors. In this cross-sectional study, secondary analyses of data from two clinical trials were conducted to determine which personality dimensions contributed to body dissatisfaction in women with bulimia nervosa, and whether low self-esteem and depression mediate these associations independently or in serial. METHOD: Participants were 193 women with bulimia nervosa. Participants completed self-report measures of temperament and character, body dissatisfaction, low self-esteem, and depression before receiving treatment for their eating disorder. RESULTS: The temperament dimension, harm avoidance, contributed significantly to body dissatisfaction. Serial mediation analyses showed this association was fully mediated, revealing two significant indirect effects. The first was through low self-esteem and the second through depression and low self-esteem in serial. CONCLUSIONS: Findings suggest body dissatisfaction in women with bulimia nervosa may be indirectly targeted through addressing harm avoidance, depression and low self-esteem.

Specialist supportive clinical management for anorexia nervosa: Analysis of therapy content and relation to outcome.

OBJECTIVE: Psychotherapy for anorexia nervosa (AN) is complex and multifaceted, with little known about likely effective components of treatments. The current study explored the spoken content of specialist supportive clinical management (SSCM) for AN, a treatment with evidence of effectiveness in several randomized clinical trials. METHOD: One hundred seventy-eight therapy sessions constituting all ten therapist-patient dyads of those who completed SSCM treatment in the original clinical trial of SSCM, were transcribed verbatim. Themes were developed and content analyzed using qualitative content analysis of complete therapy sessions by four analysts, with 10% of sessions cocoded for interrater agreement. RESULTS: Over three quarters of session content was within the clinical management theme, the largest subtheme relating to normalizing eating, followed by weight, mechanics of SSCM, and encouragement of self-care. Approximately 20% of total content was in the supportive psychotherapy theme, half about relationships. The relative proportion of clinical management content remained high, decreasing during the last five sessions. Those achieving good outcome did not have a lower ratio of clinical management to supportive psychotherapy content. DISCUSSION: The current study revealed strong clinical management focus on core symptoms of AN-normalization of eating and weight gain-throughout SSCM for AN. PUBLIC SIGNIFICANCE: Six clinical trials have found SSCM to be effective in treating AN. Content of SSCM sessions in the original trial was classified using qualitative content analysis. Study findings revealed strong clinical management focus on core AN symptoms-normalization of eating and weight gain-throughout SSCM, with the ratio of clinical management to supportive psychotherapy greater for those with a good outcome.

Long-term efficacy of metacognitive therapy and cognitive behaviour therapy for depression.

OBJECTIVE: To examine the two-year outcomes for depression, anxiety, cognitive and global social functioning after cognitive behavioural therapy (CBT) and metacognitive therapy (MCT) for depression. METHOD: Participants were 31 adults with a diagnosis of major depressive disorder in a randomised pilot study comparing MCT and CBT. Therapy modality differences in change in depression and anxiety symptoms, dysfunctional attitudes, metacognitions, rumination, worry and global social functioning were examined at the two-year follow-up for those who completed therapy. RESULTS: Significant improvements, with large effect sizes, were evident for all outcome variables. There were no significant differences in outcome between CBT and MCT. The greatest change over time occurred for depression and anxiety. Large changes were evident for metacognitions, rumination, dysfunctional attitudes, worry and global social functioning. Sixty-seven percent had not experienced a major depression and had been well during all of the past year, prior to the follow-up assessment. CONCLUSION: The finding at end treatment, of no modality specific differences, was also evident at two-year follow-up. Although CBT and MCT targeted depression, improvements were much wider, and although CBT and MCT take different approaches, both therapies produced positive change over time across all cognitive variables. CBT and MCT provide treatment options, that not only improve the longer-term outcome of depression, but also result in improvements in anxiety, global social functioning and cognitive status.

Personality traits and night eating syndrome in women with bulimia nervosa and binge eating disorder.

PURPOSE: Previous research suggests that eating disorders may be associated with certain personality profiles; however, there is limited research investigating associations with night eating syndrome (NES). This research suggests harm avoidance personality trait is higher in NES individuals than in the general population, however, evidence of associations with other personality traits is inconsistent. To understand which personality traits are associated with NES symptoms, the current study aimed to improve understanding of the relationship between NES symptoms and a range of personality traits, addressing limitations in the earlier literature in this area by controlling for common confounders. METHODS: Baseline data were analysed from an outpatient psychotherapy trial for 111 women with bulimia nervosa or binge eating disorder. Pre-treatment measures of personality traits (measured with the Temperament and character inventory-revised) and NES symptoms (measured with the Night eating questionnaire) were used. Regression analyses tested associations between these variables, adjusting for potential confounders, including age and ethnicity. RESULTS: Low cooperativeness scores were associated with greater NES symptoms in the multivariable model (mean difference: - 0.10, 95% confidence intervals: - 0.20 to - 0.01, p = 0.033). There was weak evidence of associations between both high harm avoidance and low self-directedness personality traits and greater NES symptoms. CONCLUSIONS: This study adds to the limited research measuring associations between a range of personality traits and NES, addressing limitations of previous research. Weak evidence for an association between high harm avoidance and low self-directedness and increased NES symptoms was found. A novel association was found between low cooperativeness and greater NES symptoms. Further research is needed to validate its presence in those with and without comorbid eating disorders and to examine the relative change in NES, eating disorder symptoms and personality scores in treatments focusing on cooperativeness. LEVEL OF EVIDENCE: Level IV (cross-sectional data from a randomised controlled trial, CTB/04/08/139).

The five year outcome of major depression: Effects of baseline variables and type of treatment.

BACKGROUND: Depression is commonly a relapsing or chronic disorder. Long-term outcome is therefore important. We report on the outcome of major depression five years after receiving treatment with medication or psychotherapy. METHODS: 472 patients were treated in three consecutive randomised controlled trials in one clinical research centre. 298 were followed up at five years. Of these, 106 patients were treated with medications, while the remaining 192 were given psychotherapy. The a priori outcome measure was mood symptoms in the two years prior to the assessment. RESULTS: The majority (56%) of patients had no depressive symptoms in the prior two years. One third (32%) had fluctuating depression, while 12% were chronic depressed. Predictors of outcome were few; baseline severity, suicidality, personality pathology, and type of treatment. Those receiving medication did somewhat worse, even when adjusted for this group's higher depression severity, suicidality and personality pathology at baseline. CONCLUSIONS: Long-term depressive symptoms are common after evidence-based treatment, although over half the patients appear to recover. Psychotherapy may be superior to medication in reducing the level of symptoms in the longer term. Personality remains one of the few baseline predictors of long-term outcome.

Recruitment and retention of participants in longitudinal studies after a natural disaster.

Climate change and population growth will increase vulnerability to natural and human-made disasters or pandemics. Longitudinal research studies may be adversely impacted by a lack of access to study resources, inability to travel around the urban environment, reluctance of sample members to attend appointments, sample members moving residence and potentially also the destruction of research facilities. One of the key advantages of longitudinal research is the ability to assess associations between exposures and outcomes by limiting the influence of sample selection bias. However, ensuring the validity and reliability of findings in longitudinal research requires the recruitment and retention of respondents who are willing and able to be repeatedly assessed over an extended period of time. This study examined recruitment and retention strategies of 11 longitudinal cohort studies operating during the Christchurch, New Zealand earthquake sequence which began in September 2010, including staff perceptions of the major impediments to study operations during/after the earthquakes and respondents' barriers to participation. Successful strategies to assist recruitment and retention after a natural disaster are discussed. With the current COVID-19 pandemic, longitudinal studies are potentially encountering some of the issues highlighted in this paper including: closure of facilities, restricted movement of research staff and sample members, and reluctance of sample members to attend appointments. It is possible that suggestions in this paper may be implemented so that longitudinal studies can protect the operation of their research programmes.

Outpatient therapy for adult anorexia nervosa: Early weight gain trajectories and outcome.

OBJECTIVE: The purpose of the study was to identify latent classes of trajectory of change in body mass index (BMI) between the initial and thirteenth session of outpatient treatment for adult anorexia nervosa and identify the association with outcome. METHOD: Participants (n = 120) were randomised to one of three outpatient therapies. RESULTS: Four latent classes were identified; two classes (higher, rapid and higher, moderate) had BMI > 17 kg/m2 at initial assessment, and both gained significantly more weight over the 13 sessions compared to the other two classes. The third and fourth classes (middle, stable and low, stable) had an initial BMI of 16.44 and 15.31, respectively, and neither gained weight over the first 13 sessions. Compared to the other three classes, the higher, rapid class (N = 19, 16%) showed a significantly greater BMI increase over the first 13 sessions of therapy and a significantly higher rate of remission at end of treatment and 12-month follow-up (18-22 months post-randomisation). CONCLUSIONS: The group with the greatest early weight gain had significantly higher levels of remission. Higher BMI at baseline without substantial early weight gain was insufficient to produce higher levels of remission than those with lower weight at baseline.

Evidence-based treatments remain the best intervention for good long-term outcome of severe and enduring anorexia nervosa.

More research is needed about response to specialist treatments for severe and enduring anorexia nervosa. Current evidence suggests those with severe and enduring anorexia nervosa respond to evidence-based treatments and continue to recover over decades. In the absence of clear guidelines to the contrary and given our understanding of the superior efficacy of specialist treatments over more eclectic treatment choices, it is our responsibility to continue to train and supervise clinicians to deliver evidence-based treatments, irrespective of the variant of anorexia nervosa.

Specialist Supportive Clinical Management for anorexia nervosa: what it is (and what it is not).

OBJECTIVE: Specialist Supportive Clinical Management (SSCM) is a psychotherapy comprising a clinical management focus addressing anorexia nervosa (AN) symptoms and a supportive therapy component. SSCM has been an active control therapy in randomised controlled trials for AN, but has proven to be an effective therapy in its own right. There has been speculation about how this relatively straightforward therapy works. Some of the commentaries and descriptors used for SSCM, however, do not reflect the content or principles of SSCM. This paper clarifies areas of misunderstanding by describing what SSCM is and what it is not, particularly in relation to commentary about its constituent characteristics. CONCLUSIONS: SSCM utilises well established clinical management for AN (with a sustained focus on normalised eating and weight restoration) coupled with supportive therapy principles and strategies. Common factors across both arms include core counselling skills and a positive therapeutic alliance to promote adherence and retention in treatment for AN. Compared to other comparator therapies to date, SSCM is a simpler therapy without unique or novel theoretically derived strategies. Comparable outcomes with more complex psychotherapies raise the question of whether the combined core components of SSCM may be sufficient for many people with AN.

Earthquake brain: Impairment of spatial memory following long-term earthquake-related stress.

OBJECTIVES: The primary aim of this study was to investigate neuropsychological function in patients with earthquake-related posttraumatic stress disorder, compared with earthquake-exposed but resilient controls. We hypothesised that individuals with posttraumatic stress disorder would have poorer neuropsychological performance on tests of verbal and visuospatial learning and memory compared with the earthquake-exposed control group. The availability of groups of healthy patients from previous studies who had been tested on similar neuropsychological tasks prior to the earthquakes allowed a further non-exposed comparison. METHOD: In all, 28 individuals with posttraumatic stress disorder and 89 earthquake-exposed controls completed tests of verbal and visuospatial learning and memory and psychomotor speed. Further comparisons were made with non-exposed controls who had been tested before the earthquakes. RESULTS: No significant difference in performance on tests of verbal or visuospatial memory was found between the earthquake-exposed groups (with and without posttraumatic stress disorder), but the posttraumatic stress disorder group was significantly slowed on tests of psychomotor speed. Supplementary comparison with historical, non-exposed control groups showed that both earthquake-exposed groups had poorer performance on a test of visuospatial learning. CONCLUSION: The key finding from this study is that there were no differences in verbal or visuospatial learning and memory in individuals with posttraumatic stress disorder compared with similarly earthquake-exposed controls. Compared with non-exposed controls, both earthquake-exposed groups had poorer performance on a test of visuospatial (but not verbal) learning and memory. This offers preliminary evidence suggesting that it is earthquake (trauma) exposure itself, rather than the presence of posttraumatic stress disorder that affects aspects of neuropsychological functioning. If replicated, this may have important implications for how information is communicated in a post-disaster context.

Patient predictors of response to cognitive behaviour therapy and schema therapy for depression.

OBJECTIVE: Few studies have examined differential predictors of response to psychotherapy for depression. Greater understanding about the factors associated with therapeutic response may better enable therapists to optimise response by targeting therapy for the individual. The aim of the current exploratory study was to examine patient characteristics associated with response to cognitive behaviour therapy and schema therapy for depression. METHODS: Participants were 100 outpatients in a clinical trial randomised to either cognitive behaviour therapy or schema therapy. Potential predictors of response examined included demographic, clinical, functioning, cognitive, personality and neuropsychological variables. RESULTS: Individuals with chronic depression and increased levels of pre-treatment negative automatic thoughts had a poorer response to both cognitive behaviour therapy and schema therapy. A treatment type interaction was found for verbal learning and memory. Lower levels of verbal learning and memory impairment markedly impacted on response to schema therapy. This was not the case for cognitive behaviour therapy, which was more impacted if verbal learning and memory was in the moderate range. CONCLUSION: Study findings are consistent with the Capitalisation Model suggesting that therapy that focuses on the person's strengths is more likely to contribute to a better outcome. Limitations were that participants were outpatients in a randomised controlled trial and may not be representative of other depressed samples. Examination of a variety of potential predictors was exploratory and requires replication.

Prevalence of cognitive impairment in major depression and bipolar disorder.

OBJECTIVES: The current study examines prevalence of cognitive impairment in four mood disorder samples, using four definitions of impairment. The impact of premorbid IQ on prevalence was examined, and the influence of treatment response. METHODS: Samples were: (i) 58 inpatients in a current severe depressive episode (unipolar or bipolar), (ii) 69 unmedicated outpatients in a mild to moderate depressive episode (unipolar or bipolar), (iii) 56 outpatients with bipolar disorder, in a depressive episode, and (iv) 63 outpatients with bipolar disorder, currently euthymic. Cognitive assessment was conducted after treatment in Studies 1 (6 weeks of antidepressant treatment commenced on admission) and 2 (16-week course of cognitive behaviour therapy or schema therapy), allowing the impact of treatment response to be assessed. All mood disorder samples were compared with healthy control groups. RESULTS: The prevalence of cognitive impairment was highest for the inpatient depression sample (Study 1), and lowest for the outpatient depression sample (Study 2). Substantial variability in rates was observed depending on the definition of impairment used. Correcting cognitive performance for premorbid IQ had a significant impact on the prevalence of cognitive impairment in the inpatient depression sample. There was minimal evidence that treatment response impacted on prevalence of cognitive impairment, except in the domain of psychomotor speed in inpatients. CONCLUSIONS: As interventions aiming to improve cognitive outcomes in mood disorders receive increasing research focus, the issue of setting a cut-off level of cognitive impairment for screening purposes becomes a priority. This analysis demonstrates important differences in samples likely to be recruited depending on the definition of cognitive impairment and begins to examine the importance of premorbid IQ in determining who is impaired.

Predictors of premature termination from psychotherapy for anorexia nervosa: Low treatment credibility, early therapy alliance, and self-transcendence.

OBJECTIVE: Failure to complete treatment for anorexia nervosa (AN) is- common, clinically concerning but difficult to predict. This study examines whether therapy-related factors (patient-rated pretreatment credibility and early therapeutic alliance) predict subsequent premature termination of treatment (PTT) alongside self-transcendence (a previously identified clinical predictor) in women with AN. METHODS: 56 women aged 17-40 years participating in a randomized outpatient psychotherapy trial for AN. Treatment completion was defined as attending 15/20 planned sessions. Measures were the Treatment Credibility, Temperament and Character Inventory, Vanderbilt Therapeutic Alliance Scale and the Vanderbilt Psychotherapy Process Scale. Statistics were univariate tests, correlations, and logistic regression. RESULTS: Treatment credibility and certain early patient and therapist alliance/process subscales predicted PTT. Lower self-transcendence and lower early process accounted for 33% of the variance in predicting PTT. DISCUSSION: Routine assessment of treatment credibility and early process (comprehensively assessed from multiple perspectives) may help clinicians reduce PTT thereby enhancing treatment outcomes.

Earthquake Brain: Altered Recognition and Misclassification of Facial Expressions Are Related to Trauma Exposure but Not Posttraumatic Stress Disorder.

OBJECTIVES: The study investigated facial expression recognition (FER) in posttraumatic stress disorder (PTSD) caused by exposure to earthquakes, and in particular whether people with this condition showed a bias toward interpreting facial expressions as threat-related emotions (i.e., as anger, fear, or disgust). The study included a trauma-exposed control group who had been similarly exposed to the earthquakes but had not developed PTSD. We hypothesized that individuals with PTSD would have increased sensitivity to threat-related facial emotions compared with the trauma-exposed control group. This would be shown by increased accuracy in recognition of threat-related emotions and the misinterpretation of neutral expressions to these emotions (i.e., misidentifying them as anger, fear, or disgust). The availability of a group of healthy controls from a previous study who had been tested on a similar task before the earthquakes allowed a further non-exposed comparison. METHOD: Twenty-eight individuals with PTSD (71% female, mean age 42.8 years) and 89 earthquake-exposed controls (66% female, mean age 50.1 years) completed an FER task, which featured six basic emotions. Further comparisons were made with 50 non-exposed controls (64% female, mean age 38.5 years) who had been tested before the earthquakes. RESULTS: There was no difference in sensitivity to threat-related facial expressions (as measured by accuracy in recognition of threat-related facial expressions and the misinterpretation of neutral expressions as threatening) in individuals with PTSD compared with similarly earthquake-exposed controls. Supplementary comparison with an historical, non-exposed control group showed that both earthquake-exposed groups had increased accuracy for the identification of all facial emotions and showed a bias in the misclassification of neutral facial expressions to the threat-related emotions of anger and disgust. CONCLUSION: These findings suggest that it is exposure to earthquakes and repeated aftershocks, rather than the presence of PTSD that affects FER accuracy and misinterpretation. The importance of these biases in both PTSD and trauma-exposed controls needs further exploration and is an area for future research.

Assessing the distinctiveness of psychotherapies and examining change over treatment for anorexia nervosa with cognitive-behavior therapy, interpersonal psychotherapy, and specialist supportive clinical management.

OBJECTIVE: Therapist adherence to cognitive-behavior therapy (CBT), interpersonal psychotherapy (IPT), and specialist supportive clinical management (SSCM) for anorexia nervosa (AN), was examined across three phases of therapy in a randomized clinical trial. METHOD: Adherence in early, middle, and late phase therapy sessions from 53 of 56 participants in the trial was assessed using the CSPRS-AN by independent raters after listening to complete therapy sessions. RESULTS: The three forms of psychotherapy were distinguishable by blind raters. Subscale scores were higher for the corresponding therapy than the other therapy modalities. In CBT and SSCM, a phase-by-therapy effect was found, with the CBT subscale highest for CBT, intermediate for SSCM, lowest for IPT, and elevated in the middle phase of CBT and SSCM. The SSCM subscale was highest for SSCM, intermediate for CBT, lowest for IPT, and elevated in the middle phase of SSCM. Adherence to activities around normalizing eating, weight gain, and education about anorexia nervosa was higher in SSCM than in either CBT or IPT. DISCUSSION: Ensuring the distinctiveness of therapies in existing clinical trials with differential treatment outcome is essential. Research on adherence to therapy modalities has the potential to help understanding of the effective components of new and existing treatments for AN. © 2016 Wiley Periodicals, Inc.

Psychotherapy for transdiagnostic binge eating: A randomized controlled trial of cognitive-behavioural therapy, appetite-focused cognitive-behavioural therapy, and schema therapy.

Cognitive-behavioural therapy (CBT) is the recommended treatment for binge eating, yet many individuals do not recover, and innovative new treatments have been called for. The current study compares traditional CBT with two augmented versions of CBT; schema therapy, which focuses on early life experiences as pivotal in the history of the eating disorder; and appetite-focused CBT, which emphasises the role of recognising and responding to appetite in binge eating. 112 women with transdiagnostic DSM-IV binge eating were randomized to the three therapies. Therapy consisted of weekly sessions for six months, followed by monthly sessions for six months. Primary outcome was the frequency of binge eating. Secondary and tertiary outcomes were other behavioural and psychological aspects of the eating disorder, and other areas of functioning. No differences among the three therapy groups were found on primary or other outcomes. Across groups, large effect sizes were found for improvement in binge eating, other eating disorder symptoms and overall functioning. Schema therapy and appetite-focused CBT are likely to be suitable alternative treatments to traditional CBT for binge eating.
