“…When we studied the correlation between CDSS scores and other scales or subscales, the only high correlation was with the PANSS-D. This result is consistent with other studies [46,48] that have also found a good correlation between these two measurements, and it suggests that, with certain limitations (e.g. the PANSS-D does not evaluate important symptoms such as suicide), the PANSS-D provides a correct overall evaluation of depression in patients with schizophrenia [46,48].…”

“…There is evidence that the relationship between depression symptoms measured by the CDSS and other symptoms of schizophrenia appears to differ during different stages of the illness. The CDSS has been validated in different languages (Brazilian, Danish, French, Arabic) [45][46][47]. When we studied the correlation between CDSS scores and other scales or subscales, the only high correlation was with the PANSS-D.…”

BackgroundPsychiatric comorbidities are communal among patients with schizophrenia. A significant percentage of patients with schizophrenia show depressive symptoms during the development of their illness. ObjectivesThe aim of this study was to evaluate the prevalence of depression using the Calgary Depression Scale for Schizophrenia (CDSS) in a sample of Egyptian patients (Shebin El-Kom, Menoufiya) with schizophrenia and without a diagnosis of depression. ParticipantsIn this cross-sectional study, we included outpatients from Menoufiya University Hospital and Shebin El-Kom Educational Hospital, 20-50 years old, with a diagnosis of schizophrenia or schizophreniform disorder that had not been diagnosed with depression. MethodologyWe administered the CDSS and the Positive and Negative Syndrome Scale (PANSS) to the schizophrenia patient sample. Also, schizophrenia patients were studied according to the Diagnostic and Statistical Manual of Mental Disorders, 4th ed. criteria. ResultsA total of 120 patients were recruited and included in the statistical analysis (72 men and 48 women). Sixty-three patients had a total score of 5 or more points on the CDSS, making the prevalence of depression 30%. The prevalence of depression in men (n = 24) was 33% versus 25% in women (n = 12). There was no significant difference between men and women in terms of the prevalence of depression. The CDSS had a higher correlation with the depressive factor of the PANSS and a moderate correlation with the general psychopathology subscale of the PANSS. Nonetheless, the correlation of the CDSS total score with the PANSS-negative was low. There was no correlation between depressive symptoms and positive symptoms. ConclusionOur results suggest that patients with schizophrenia who have not been diagnosed with depression frequently have clinically symptoms of depression, with the possible exception of a contribution from negative symptoms. CDSS is a more specific instrument to measure depressive symptoms in schizophrenia.

“…Several studies have shown that there is a weak correlation/no correlation between scales for depression in patients with schizophrenia (e.g. the CDSS) and the negative subscale in the PANSS [37,38]. Similarly, our data showed no significant correlation between the scores on the negative symptom subscale and scores on the CDSS.…”

Background: The Positive and Negative Syndrome Scale (PANSS) is widely used for patients with schizophrenia. This scale is reliable and valid. The PANSS was translated and validated in several languages. Objective: The aim of this study was to translate and validate the PANSS in the Arab population. Subjects and Methods: The PANSS was translated into formal Arabic language using the back-translation method. 101 Arab patients with schizophrenia and 98 Arabs with no diagnosis of any mental disorder were recruited. The Arabic version of the Mini International Neuropsychiatric Interview (MINI-6) was used as a diagnostic tool to confirm the diagnosis of schizophrenia or rule out any diagnosis for the healthy control group. Reliability of the scale was assessed by calculating internal consistency, interrater reliability and test-retest reliability. Construct validity was assessed using the Arabic version of the MINI-6. PANSS total scores were correlated with the Clinical Global Impression-Severity scale. Results: Our findings showed that the internal consistency was good (0.92). Scores on the PANSS of the patients were much higher than those of the healthy controls. The PANSS showed good interrater reliability and test-retest reliability (0.92 and 0.75, respectively). In comparison with the MINI-6, the PANSS showed good sensitivity and specificity, which implies good construct validity of this version. Conclusion: In conclusion, the Arabic version of the PANSS is a reliable and valid instrument for the assessment of patients with schizophrenia in the Arab population.

“…For depression, we rated patients on the Spanish version of the Calgary Depression Scale for Schizophrenia (CDSS) (Addington et al, 1990;Sarró et al, 2004) and also on the PANSS depression subscale (PANSS-D) (El Yazaji et al, 2002); this combines scores on the G1 (somatic concerns), G2 (anxiety), G3 (guilt feelings), and G6 (depression).…”
