Personality psychopathology: Longitudinal prediction of change in body mass index and weight post-bariatric surgery.
Article in Health psychology : official journal of the Division of Health Psychology, American Psychological Association, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveBariatric surgery is an effective treatment for obesity, which has been increasing worldwide. However, bariatric surgery causes dramatic physical changes that can cause significant stress. Prior research has found that psychological variables such as personality traits and levels of psychopathology can influence success after bariatric surgery (in terms of body mass index [BMI] reduction and weight loss). However, most prior studies have been limited by small sample sizes, inconsistent follow up, and categorical assessment of psychopathology.
methodThe present study examines the predictive utility of the Personality Assessment Inventory (PAI) scales for three bariatric surgery outcomes (BMI reduction, weight loss, and percent excess weight loss [%EWL]) across 10 follow-up points 5 years after surgery. It also examines the largest sample of bariatric surgery-completing patients (
resultsResults indicate that personality and psychopathology variables predicted less BMI reduction, weight loss, and %EWL 5 years after surgery and also affected the trajectories of change in the outcome variables across time. The PAI scales predicted more variance in the 5-year BMI outcomes than did age and gender. The most robust effects were for scales assessing phobias, traumatic stress, identity problems, and negative relationships.
conclusionThe PAI may be useful to clinical health psychologists who conduct recommended psychological evaluations with potential bariatric surgery candidates. (PsycINFO Database Record (c) 2020 APA, all rights reserved).
