Reliability and validity of the Turkish version of comprehensive assessment of at risk mental states

Abstract

Aims: To perform the validation of the Comprehensive Assessment at Risk Mental State (CAARMS) in Turkish.Methods: Sixty-five volunteers (15-24 years) were enrolled in this study. Concurrent validity was performed with Spearman's Correlation Test using Brief Psychiatric Rating Scale (BPRS). Median scores of the groups were compared using Mann-Whitney U Test. Interrater reliability was assessed by intragroup correlation coefficient method. Internal consistency was studied by the calculation of Cronbach Alfa Coefficient.Results: The correlation of the severity scores of the CAARMS with unusual thought content, suspiciousness, hallucinations and conceptual disorganization items of the BPRS showed that the concurrent validity was good. ROC analysis revealed that CAARMS could discriminate between individuals with UHR and healthy volunteers well. We found a good correlation between the raters. Internal consistency was at very high level. Conclusion:Analyses of concurrent validity, criterion validity, interrater reliability and internal consistency indicate that the Turkish version is valid and reliable.

Face and emotion recognition in individuals diagnosed with schizophrenia, ultra-high risk for psychosis, unaffected siblings, and healthy controls in a sample from Turkey

“…The SCZ group was confirmed to be in remission for at least six months. Comprehensive Assessment of At Risk Mental States (CAARMS) was utilized to establish the UHR group and consisted of individuals who met criteria for either brief limited intermittent psychotic symptoms (BLIPS) or attenuated psychosis or genetic risk plus functional deterioration ( Yung et al, 2005 ; Yokuşoğlu et al, 2020 ). CAARMS interviews was carried out by a senior researcher (A.U.)…”

Development of the PSYCHS: Positive SYmptoms and Diagnostic Criteria for the CAARMS Harmonized with the SIPS

“…Interrater reliability (IRR) for CHR‐P ascertainment has also been excellent, both for the SIPS (median kappa across 16 published samples 0.89) (Woods et al, 2019) and the CAARMS (median across three studies 0.845) (Fusar‐Poli et al, 2012; Miyakoshi et al, 2009; Paterlini et al, 2019). IRR for attenuated positive symptoms has also been excellent for both SIPS (median ICC across 21 published samples 0.88) (Woods et al, 2019) and CAARMS (median ICC or Pearson r across eight studies 0.89) (Braham et al, 2014; Fusar‐Poli et al, 2012; Lho et al, 2021; Miyakoshi et al, 2009; Paterlini et al, 2019; Wang et al, 2022; Yokusoglu et al, 2021; Yung et al, 2005).…”
