The effectiveness of psychological interventions on pain, disability, and psychological symptoms in whiplash-associated disorders: a systematic review and meta-analysis.
Synthesis in BMC psychology, 2026. 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
backgroundWhiplash-associated disorders (WAD) include a range of physical and psychological symptoms, profoundly impacting individuals' quality of life. The effectiveness of psychological interventions in WAD management is still uncertain. Thus, the aim of this study is to investigate the effectiveness of psychological interventions on clinical outcomes (e.g., pain, disability, psychological distress) among individuals with WAD. Are psychological interventions effective in improving clinical outcomes (e.g., pain, disability, psychological distress) among individuals with WAD?
methodsThree databases were comprehensively searched for randomized controlled trials (RCTs) that investigated the effects of psychological interventions on pain, disability, depression, stress, anxiety, or fear of movement in patients with WAD compared with control groups receiving usual care or no intervention. Meta-analyses were performed by calculating the weight mean difference (WMD), 95% CI, and P value. The Cochrane Risk of Bias tool (RoB2) was used to assess the risk of bias in the included studies.
resultsEleven RCTs met the inclusion criteria. The pooled analysis indicated a significant improvement in pain scales immediately after the intervention (WMD = 0.96, P < 0.05), and at 3-6 months and 1-year follow-ups. Disability, pain catastrophizing, and kinesiophobia improved significantly at post-intervention and after 3-6 months. In addition, the pooled analysis showed significant improvements in depression, anxiety, self-efficacy, and stress symptoms post-intervention.
conclusionsThis systematic review provides varied evidence for the effectiveness of psychological interventions on pain, disability, and psychological symptoms in WAD. These immediate and long-term benefits in favor of psychological interventions are critical in the chronic pain management of WAD. Future research should focus on refining the most effective psychological interventions, considering cultural and contextual factors.
