Mindfulness improves negative psychotic symptoms through reducing emotional and social withdrawal.
Trial report in World journal of psychiatry, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundPsychotic disorders are characterized by both positive symptoms (hallucinations, delusions) and negative symptoms (emotional blunting, anhedonia) that impair daily functioning. While antipsychotic drugs and psychological interventions are effective when addressing positive symptoms, treatment of negative symptoms remains an ongoing challenge. Mindfulness-based interventions (MBIs) have been shown to reduce negative psychotic symptoms. However, as negative psychotic symptoms are assessed as a sole entity rather than a sum of manifestations, the effect of MBIs remains unclear.
aimTo examine the effects of MBI in addition to integrated rehabilitation treatment (IRT) for people experiencing psychosis on each of the negative psychotic symptoms.
methodsA randomized controlled clinical trial with preintervention and postintervention measures was designed. The main outcome variable was negative psychotic symptoms assessed through the seven subscales of the Spanish version of the positive and negative syndrome scale. Data were analyzed using a repeated measures analysis of variance and reliable change index calculation.
resultsThere were no statistical differences between groups at the preintervention assessment. Statistically significant differences were found after MBI for the time in emotional withdrawal (
conclusionMBI added to IRT reduced the lack of interest and involvement with affective commitment to daily life activities, and interest and engagement in social activities increased. These negative psychotic symptoms were not improved by IRT alone.
