Anorexia Nervosa Clinical Trial
— SF-EDOfficial title:
Targeting Social Function to Improve Outcomes in Eating Disorders
Social processing and cognition are often altered in patients with eating disorders. The goal of this clinical trial is to assess two different social therapeutic interventions -- one educational, one interactive -- for their effectiveness in improving clinical outcomes in patients with eating disorders. Patients in both interventions will receive education about social function in eating disorders, but those in the interactive treatment group will complete an additional collaborative art task. Participants will: - attend a baseline study visit to complete clinical interviews, cognitive testing, and behavioral tasks - complete a pre-intervention assessment with questionnaires - attend eight sessions of their assigned treatment group over the course of 12 weeks - complete three virtual follow-up assessments 4, 8, and 12 months from their baseline - attend a final study visit to repeat some clinical interviews, cognitive testing, and behavioral tasks Researchers will compare changes in eating disorder, mood, and anxiety symptoms as well as test results from baseline and final study visits for each group to see if - patients can be treated effectively with education alone or if an interactive group component produces additional benefits - cognitive and behavioral task performance are associated with recovery or illness state.

Primary | Change in eating disorder symptoms | The Eating Disorder Examination Questionnaire (EDE-Q) measures the severity of eating disorder symptoms. Possible scores on global eating disorder pathology range from 0 to 6, with higher scores indicating greater severity. Scores of 2 or less are considered typical of normative eating behavior/cognitions, while scores of 3-6 suggest the presence of clinically significant eating disorder symptoms. | pre-intervention (T0) to four months from start of intervention (T4) | |

Primary | Change in depression symptoms | The Patient Health Questionnaire (PHQ-9) is a 9-item measure of depression symptoms. Each item is rated on a four-point scale (0 = not at all; 1 = several days; 2 = more than half the days; 3 = nearly every day). Possible scores range from 0-27, allowing depression to be categorized as minimal (1-4), mild (5-9), moderate (10-14), moderately severe (15-19), or severe (20-27). | pre-intervention (T0) to four months from start of intervention (T4) | |

Primary | Change in overall levels of psychopathology | The DSM-5 Cross-Cutting Symptom Measure (DSM-XC) is a 23-item measure of overall levels of psychopathology across 13 psychiatric domains. Each item on the measure is rated on a 5-point scale (0=none or not at all; 1=slight or rare, less than a day or two; 2=mild or several days; 3=moderate or more than half the days; and 4=severe or nearly every day). The score on each item within a domain should be reviewed. Because additional inquiry is based on the highest score on any item within a domain, the clinician is asked to indicate that score in the "Highest Domain Score" column | pre-intervention (T0) and at the last post-intervention follow-up (T12) | |
Primary | Change in eating disorder diagnosis | The Eating Disorder Diagnostic Assessment for DSM-5 (EDA-5) is a semi-structured clinical interview meant to assist in the assessment of a feeding or eating disorder according to DSM-5 criteria. | baseline and final study visits (approximately 1 year apart) | |
Secondary | Change in verbal learning and memory | California Verbal Learning Test (CVLT-3) is an individually administered assessment that measures both recall and recognition of two lists of words over a number of immediate and delayed memory trials. The CVLT 3 Core Report contains demographics, a core score summary, a scaled score profile, a standard score summary, a process score summary, and demographically adjusted core and standard scores, if selected. Item responses for all recall trials can also be selected for inclusion on the report. | baseline and final study visits (approximately 1 year apart) | |
Secondary | Change in visuospatial learning and memory | Ruff-Light Trail Learning Test (RULIT) is a measure of visuospatial learning and memory. The respondent is given a stimulus card containing a complex configuration of circles interconnected by lines and asked to use an index finger to trace a line connecting the circles from the START to the END. The task is repeated until participants trace the correct path in two consecutive trials. Immediate Memory is assessed by the number of steps correctly completed in Trial 2. Learning is assessed by the number of trials to master the task and the cumulative number of errors across Trials 2 through 10 (or until the task is mastered), and Long-term Recall is evaluated by having the respondent retrace the trail after a 60-minute delay. | baseline and final study visits (approximately 1 year apart) | |
Secondary | Change in sense of social connectedness | The Social Connectedness Scale (SCS) is a self-report questionnaire that measures the extent to which individuals feel connected to others in their social environment. It consists of 20 items that assess four different dimensions of social connectedness that include belongingness, closeness, support, and satisfaction. Individuals rate each item on a 6-point Likert scale, from 1 (strongly disagree) to 6 (strongly agree). Higher scores indicate a greater sense of social connectedness. | pre-intervention (T0) to four months from start of intervention (T4) | |

Secondary | Change in trait self-esteem | Rosenberg trait self-esteem Scale (TSE) is a 10-item measure of global self-worth. Each item is rated on a four-point Likert scale from (1 = strongly disagree, 2 = disagree, 3 = agree, 4 = strongly agree) and five items are reverse scored. Higher scores indicate higher self-esteem. | pre-intervention (T0) to four months from start of intervention (T4) | |

Secondary | Change in social learning rates | Cyberball is is an online ball-tossing game that participants believe they are playing with three others. In the version we are using, one player (good) preferentially includes the participant, one (neutral) is equitable, and another player (bad) stops throwing the ball to the participant. Changes in the percentage of throws to each type of player indicate responsivity to social learning. The percentage of throws to the good player will increase while the percentage of throws to the bad player will decrease as participants become more attuned to valence of social interactions. | baseline to final study visit (approximately 1 year apart) | |
Secondary | Change in social reward learning | The Trust Game is a tend-round economic game in which two players take turns acting as "investor" and "trustee." The investor is given $20 and sends a portion to the trustee. The trustee receives three times the invested amount and returns some amount to the investor. This task provides total amounts earned; larger amounts indicate more attunement to the partner's behavior. We hypothesize that this will increase after the intervention due to improved sensitivity to others. | baseline to final study visit (approximately 1 year apart) | |
Secondary | Change in social learning biases | The Evaluation Learning Task presents participants with 6 computer personas across two conditions (self-referential or other-referential). Participants are given word pairs (e.g. 'witty' vs. 'dull') and are asked to guess which word the computer persona would use to describe them (SR) or 'George' (OR). Using the feedback on their selections (correct or incorrect), they must decide whether the computer persona liked or disliked them and to what degree (%). Participant response times and proportion of correct responses in each condition (like, neutral, or dislike) are used to evaluate learning rates and biases in each condition. | baseline to final study visit (approximately 1 year apart) | |
Secondary | Change in attribution biases | The Causal Attribution Task measures latent tendency to attribute positive and negative everyday events to internal (vs external) and global (vs specific) causes. | baseline to final study visit (approximately 1 year apart) |
