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

Negative symptoms are often enduring and lead to poor functional outcomes in individuals with schizophrenia. The cognitive model of negative symptoms proposes that low expectancies of success contribute to the development and maintenance of negative symptoms; however, longitudinal investigations assessing these beliefs and negative symptoms are needed. The current study examined whether an individual's baseline expectancies of success - one's beliefs about future success and goal attainment - predicted negative symptoms reduction over 18 months in individuals with schizophrenia-spectrum disorders (n=118). Data were collected at baseline, 9 months, and 18 months as part of a randomized controlled trial of Illness Management and Recovery. A mixed effects regression analysis revealed a significant reduction in negative symptoms over time, with a significant interaction effect between time and baseline expectancies of success. After controlling for baseline negative symptoms, demographic variables, and treatment conditions, those with high and moderate baseline expectancies of success evidenced a significant reduction in negative symptoms at 18 months, while those with low baseline expectancies of success did not evidence reduced negative symptoms. Findings support the cognitive model of negative symptoms and suggest that expectancies of success may be a useful treatment target for interventions aimed at reducing negative symptoms.
