1 · What the graph read from it

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.

Abstract

objectiveNegative symptoms significantly impact the psychosocial functioning of individuals with schizophrenia and remain difficult to address with pharmacological treatment alone. While effective psychosocial interventions are limited, online psychotherapy has emerged as a cost-effective and accessible alternative to traditional face-to-face therapy. This prospective, non-randomized study aimed to examine the effectiveness of non-face-to-face behavioral activation (BA) treatment of negative symptoms in patients with schizophrenia.

methodsA total of 98 patients were recruited from community mental health centers, a hospital, and a clinic. Participants were assigned to either a BA treatment group (n=49, 69.4% from community centers) or a treatment-as-usual (TAU) group (n=49, 83.7% from a hospital or clinic). The BA program is conducted weekly for 40 minutes by psychologists. The TAU received case management, supportive psychotherapy, counseling, psychoeducation, and ongoing or planned treatments, excluding elements of cognitive behavior therapy or BA. Positive and Negative Syndrome Scale (PANSS), Clinical Assessment Interview for Negative Symptoms (CAINS), and Behavioral Activation for Depression Scale (BADS) were administered pre- and post-treatment to assess changes in negative symptoms and behavior activation.

resultsThe BA group's PANSS negative scores improved by 2.94 (95% confidence interval [CI]=1.08-4.80, p=0.002), and CAINS total scores improved by 5.14 (95% CI=2.59-7.70, p<0.001). The BA group's motivation/pleasure scores (of CAINS) increased by 4.08 (95% CI=2.16-6.00, p<0.001). Also, in the change of BADS total score was -8.74 (95% CI=-15.64- -1.83, p=0.014), and activation score was -3.63 (95% CI=-6.94-0.33, p=0.031).

conclusionNon-face-to-face BA treatment is a more effective psychological treatment than TAU for negative symptoms of patients with schizophrenia. (Trial Registration: ClinicalTrials.gov ID 'NCT05764148').
