Test-retest reliability (stability Good Reported as .83 [2] Repeatability Not published No published studies formally checking repeatability PHQ-15: Norms Excellent Two large studies with convenience and random samples used. One research studies (N=906) in clinical sample and one research study (N=6000) in nonclinical sample. [2]
The General Health Questionnaire (GHQ) is a psychometric screening tool to identify common psychiatric conditions. [1] It has been translated and validated in at least two languages in addition to English, including Spanish [2] and Persian. [3] The latter used in different fields and generations. [4]
The psychometric properties of the GPCOG are good. The reliability of the patient section is high. For the informant interview, reliability is satisfactory. In the original validation sample of 380 participants, the sensitivity of the GPCOG was 0.85, the specificity was 0.86.
A depression rating scale is a psychometric instrument (tool), usually a questionnaire whose wording has been validated with experimental evidence, having descriptive words and phrases that indicate the severity of depression for a time period. [1]
The SSD-12 is composed of 12 items. Each of the three psychological sub-criteria of DSM-5 somatic symptom disorder (cognitive, affective, behavioral) [2] is measured by four items with all item scores ranging between 0 and 4 (0 = never, 1 = rarely, 2 = sometimes, 3 = often, 4 = very often).
Gierk et al. (2015) [9] compared the psychometric properties of the SSS-8 and the PHQ-15 in a sample of 131 psychosomatic patients. The sum scores of both questionnaires showed a very high correlation ( r = 0.83).
Research suggests that the MSI-BPD demonstrates good accuracy in identifying potential BPD cases. Zanarini's initial validation study in 2003 found the instrument to be both sensitive (81%) and specific (85%) in correctly classifying individuals when using a cutoff score of 7.
