A Chinese version of the Psychotic Symptom Rating Scales: psychometric properties in recent-onset and chronic psychosis
Open accessAbstract
The purpose of this study was to test the reliability, validity, and factor structure of a Chinese version of the Psychotic Symptom Rating Scale (PSYRATS) in 198 and 202 adult patients with recent-onset and chronic psychosis, respectively. The PSYRATS has been translated into different language versions and has been validated for clinical and research use mainly in chronic psychotic patients but not in recent-onset psychosis patients or in Chinese populations. The psychometric analysis of the translated Chinese version included assessment of its content validity, semantic equivalence, interrater and test-retest reliability, reproducibility, sensitivity to changes in psychotic symptoms, internal consistency, concurrent validity (compared to a valid psychotic symptom scale), and factor structure. The Chinese version demonstrated very satisfactory content validity as rated by an expert panel, good semantic equivalence with the original version, and high interrater and test-retest (at 2-week interval) reliability. It also indicated very good reproducibility of and sensitivity to changes in psychotic symptoms in line with the symptom severity measured with the Positive and Negative Syndrome Scale (PANSS). The scale consisted of four factors for the hallucination subscale and two factors for the delusion subscale, explaining about 80% of the total variance of the construct, indicating satisfactory correlations between the hallucination and delusion factors themselves, between items, factors, subscales, and overall scale, and between factors and relevant item and subscale scores of the PANSS. The Chinese version of the PSYRATS is a reliable and valid instrument to measure symptom severity in Chinese psychotic patients complementary to other existing measures mainly in English language.

The C-PSYRATS showed good internal consistency, satisfactory concurrent, construct and content validity, and satisfactory test-retest reliability in Chinese people with psychosis.
“The C-PSYRATS showed good internal consistency (Cronbach’s α = 0.86 and 0.90 for the AHS and DS, respectively, and 0.89 for the overall scale). It also demonstrated satisfactory concurrent (Pearson’s r = 0.48 to 0.75, p = 0.003), construct (GFI = 0.097, Tucker–Lewis index [TLI] = 1.04, p = 0.02) and content validity, as well as satisfactory test–retest reliability (intraclass correlation”

The Results (Internal consistency and Test–retest reliability) and Discussion support the overall claim of good reliability and validity in Chinese patients with recent-onset and chronic psychosis. However, the citing sentence mislabels the reported r=0.48–0.75 as concurrent validity; the Results (Construct validity) use it for factor–item correlations. That section reports AGFI=0.97, not GFI=0.097, and gives P=0.54 for the six-factor model, not P=0.02. (LLM, conf=0.88)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
