The Physical Symptom Scale-8: Psychometric Characteristics of a Short-Form Version of the PHQ-15 and its Use in TMD-Related Assessment and Research.
Article in Journal of oral & facial pain and headache, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
aimsTo describe the development of the Physical Symptom Scale-8 (PSS-8) and to examine its psychometric properties and use in temporomandibular disorder (TMD)-related assessment and research.
methodsAn online survey comprising demographic variables, the DC/TMD pain screener (TPS), Short-Form Fonseca Anamnestic Index (SFAI), PSS-8, PHQ-15, and Depression, Anxiety, and Stress Scale-21 (DASS-21) was administered to young adults attending a technical college. The PSS-8 adopted the Somatic Symptom Scale-8 (SSS-8) items but maintained the 3-point response scale and 4-week time frame of the PHQ-15. Internal consistency and reliability of the PSS-8 were determined by its Cronbach α value. Known-groups and concurrent/convergent validity were examined using Mann-Whitney U test and Spearman correlation (α = .05), respectively.
resultsResponses from 400 participants (mean age 18.8 ± 1.5 years; 52.3% women) were evaluated. Pain-related (WPT) and all (WAT) TMDs were present in 8.5% and 17.3% of the sample, respectively. The PSS-8 exhibited good internal consistency (α = 0.82) and sound known-groups validity, with the WPT/WAT groups having significantly higher PSS-8 scores than those without TMDs. Good concurrent and convergent validity were also observed, with moderate to strong correlations with the PHQ-15 (rs = 0.97) and DASS-21 scores (rs = 0.48 to 0.60). Correlations with the TPS and SFAI scores were weaker (rs = 0.28 to 0.34).
conclusionThe PSS-8 presented good psychometric properties and performed similarly to the PHQ-15. It holds promise as the "de facto" shortened version of the PHQ-15 for TMDs and related work.
