Cross-cultural adaptation and validation of the Spanish version of the Calgary Depression Scale for Schizophrenia

Sarró, S·2004·Schizophrenia Research

Abstract

Background The Calgary Depression Scale for Schizophrenia (CDSS) is a valid tool to assess depression in schizophrenics and has been translated, adapted, and validated to be used in different non-English languages. Therefore, it may be predicted that a Spanish version of this scale will be also a valid instrument to assess symptoms of depression in patients with schizophrenia.Objective We determined the validity of the Spanish version of the Calgary scale (CDSS-S).Methods Outpatients and inpatients (n=93) diagnosed as having schizophrenia by DSM-IV criteria confirmed by SCID-IV interview were included. The Positive and Negative Syndrome Scale (PANSS), Hamilton Depression Rating Scale (HDRS-17 and HDRS-21 items), Montgomery-Asberg Depression Rating Scale (MADRS), Extrapyramidal Symptoms Rating Scale (ESRS), and Barnes Acathisia Rating Scale were administered by a first rater, whereas the CDSS-S was assessed by a second independent rater.Results The internal consistency (Cronbach's alpha 0.83) and the interrater reliability (>0.73 intraclass correlation coefficient [ICC] for single items and 0.92 for total score) were good. The test-retest reliability was high (ICC of 0.89). The scale showed a good construct validity with statistically significant correlations with HDRS-17, HDRS-21, MADRS, and G6 item (depression) of PANSS. The CDSS showed no correlation with the positive subscale of PANSS and a weak correlation with the negative subscale, general psychopathology subscale, and total score of PANSS. A cut point of five showed 94.7% sensitivity, 86.5% specificity, and 70% and 98% positive and negative predictive values, respectively.Conclusions The Spanish version of CDSS is a valid instrument to assess depressive episodes for stabilized and acute patients with schizophrenia.

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.
