Abstract
Previous research has shown a robust association between sudden gains (SGs) and treatment outcome in psychotherapy for various mental disorders including anorexia nervosa (AN). However, little is known about factors contributing to SGs. This study investigated the role of general change mechanisms in body-weight related SGs in AN. Data were drawn from a randomized-controlled trial on cognitive-behavioral therapy (CBT) and focal psychodynamic therapy (FPT) for adult outpatients with AN. Session-level data on the general change mechanisms 'clarification' (insight), 'mastery' (coping), and 'therapeutic relationship' were analyzed. Pre-gain sessions were compared with control (pre-pre-gain) sessions in 99 patients with a SG in body weight. Additionally, propensity score matching was used to compare data from pre-gain sessions from 44 patients with SG and data from the corresponding session from 44 patients without SG. In the pre-gain session, patients experienced higher levels of clarification and mastery but not therapeutic relationship. Compared to patients without a SG, patients with a SG likewise experienced more clarification and mastery but not a better therapeutic relationship in the pre-gain/corresponding session. CBT and FPT did not differ regarding these effects. The findings suggest that general change mechanisms contribute to SGs in CBT and FPT for AN.

Abstract
OBJECTIVE Eating Disorder-15 (ED-15) is a self-report scale recommended for use to evaluate weekly progress and treatment results in eating disorders. This research aims to examine the factor structure, psychometric properties, validity, and reliability of the Turkish version of ED-15 (ED-15-TR) for clinical and non-clinical samples. METHOD Translation-back translation method was used for language equivalence of ED-15-TR. The research was conducted with a total of 1049 volunteers, with two sample groups as non-clinical (n=978) and clinical (n=71). The participants completed an information form, ED-15-TR, Eating Disorder Examination Scale (EDE-Q), and Beck Depression Inventory (BDI). Three hundred fifty-two participants from the non-clinical group and 18 from the clinical group completed ED-15-TR again within a week. RESULTS Factor analysis confirmed the two-factor structure of ED-15- TR. Cronbach's alpha value was 0.911 (0.773, and 0.904 for the two subscales respectively), the intraclass correlation coefficient for testretest reliability was 0.943 in the clinical group (0.906, and 0.942 for the two subscales respectively); 0.777 (0.699, and 0.776 for the two subscales respectively) in the non-clinical group (for all p<0.001). The high level of a positive correlation between ED-15-TR and EDE-Q supported concurrent validity. CONCLUSION This research indicates that ED-15-TR is an acceptable, valid, and reliable self-report scale for Turkish society.

Sudden Gains in Two Trauma-Focused Treatments for Posttraumatic Stress Disorder. Behav Ther 2022; 53:255-266. [PMID: 35227402 PMCID: PMC8896295 DOI: 10.1016/j.beth.2021.08.003] [Citation(s) in RCA: 14] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/25/2021] [Revised: 08/20/2021] [Accepted: 08/24/2021] [Indexed: 11/22/2022]
Abstract
In the current study, we examined the degree to which sudden gains (large, rapid, and stable symptom reduction in a one-session interval) predicted treatment outcome in adults randomized to two different trauma-focused treatments. Adults diagnosed with PTSD were randomized to either written exposure therapy (WET; n = 63), a brief, exposure-based treatment for posttraumatic stress disorder (PTSD), or the more time-intensive Cognitive Processing Therapy (CPT; n = 63). Findings showed that 20.6% of participants who received WET and 17.5% of participants who received CPT experienced sudden gains. Sudden gains occurred earlier in WET (M session = 2.69, SD = 0.75) than in CPT (M session = 5.64, SD = 3.01). However, there were no treatment condition differences in the magnitude of the sudden gains. Treatment outcomes were significantly better for those who experienced sudden gains compared with those who did not, regardless of treatment assignment. Exploratory analyses of participants' trauma narratives revealed that expressing more negative emotion predicted the occurrence of sudden gains in both treatment conditions. Negative beliefs about the self and others did not predict sudden gains. The findings are discussed in terms of how they may help identify individual early response patterns that predict outcomes in trauma-focused treatments.

Abstract
The aim of this study was to validate the latest version of the Eating Problem Checklist (EPCL), a tool designed to assess eating-disorder behaviours and psychopathology in patients with eating disorders, session-by-session. The EPCL was completed at baseline by participants with eating disorders (n = 161) and a healthy control group (n = 379) and then administered session-by-session in a subgroup of 75 participants with eating disorders. The EPCL demonstrated good internal consistency, test-retest reliability, and concurrent and criterion validity, and principal axis analysis of the session-by-session data identified two factors ('eating concerns' and 'body image concerns') that accounted for 51.3% of the variance. Furthermore, session-by-session analysis indicated that the EPCL is able to identify specific weekly improvements and/or deterioration in eating-disorder psychopathology. These findings suggest that the EPCL is a valid and reliable self-report questionnaire that provides relevant clinical information regarding weekly changes in eating-disorder behaviours and psychopathology in patients with eating disorders.

Abstract
OBJECTIVE Increasing evidence suggests that mindfulness- and acceptance-based psychotherapies (MABTs) for bulimia nervosa (BN) and binge eating disorder (BED) may be efficacious; however, little is known about their active treatment components or for whom they may be most effective. METHODS We systematically identified clinical trials testing MABTs for BN or BED through PsychINFO and Google Scholar. Publications were categorized according to analyses of mechanisms of action and moderators of treatment outcome. RESULTS Thirty-nine publications met inclusion criteria. Twenty-seven included analyses of therapeutic mechanisms, and five examined moderators of treatment outcome. Changes were largely consistent with hypothesized mechanisms of MABTs, but substandard mediation analyses, inconsistent measurement tools, and infrequent use of mid-treatment assessment points limited our ability to make strong inferences. DISCUSSION Analyses of mechanisms of action and moderators of outcome in MABTs for BN and BED appear promising, but the use of more sophisticated statistical analyses and adequate replication is necessary.

Cartwright A, Cheng YP, Schmidt U, Landau S. Sudden gains in the outpatient treatment of anorexia nervosa: A process-outcome study. Int J Eat Disord 2017; 50:1162-1171. [PMID: 28842934 DOI: 10.1002/eat.22773] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/16/2017] [Revised: 07/30/2017] [Accepted: 08/11/2017] [Indexed: 01/22/2023]
Abstract
OBJECTIVE Sudden gains (SGs), broadly defined as sudden symptom reductions occurring between two consecutive treatment sessions, have been associated with improved treatment outcomes in anxiety and depression. The present study is the first to formally define SGs in anorexia nervosa and explore the characteristics, demographic and baseline clinical predictors, and clinical impact of SGs in anorexia nervosa. METHOD This is a secondary analysis of data from 89 outpatients with broadly defined anorexia nervosa who received one of two psychotherapeutic interventions as part of the MOSAIC trial (Schmidt et al., 2015). SGs were defined using session-by-session body mass index (BMI) measures. This study investigated whether SGs were associated with changes in BMI, eating disorder symptomology, general psychopathology, and psychosocial impairment between baseline and 6, 12, and 24 months follow-up. RESULTS SGs, experienced by 61.8% of patients, mostly occurred during the early and middle phases of treatment. A larger proportion of SGs predicted larger increases in BMI between baseline and 6, 12, and 24 months follow-up. Amongst those experiencing at least one SG, fewer days between baseline and a patient's first SG predicted a larger increase in BMI between baseline and both 6 and 12 months follow-up. The proportion and timing of SGs did not predict changes in other outcome measures. DISCUSSION SGs in BMI during the outpatient treatment of anorexia nervosa are clinically useful predictors of longer-term weight outcomes.
