[Validation of the Cognitive Impairment in Psychiatry (SCIP-S) Screen Scale in Patients with Bipolar Disorder I].

Background: The Spanish version of the cognitive impairment in psychiatry scale screening scale has been developed as a response to the needs arising in clinical practice during the evaluation of mental illness patients, but the performance is not known in the Colombian population with bipolar disorder I. This paper tries to establish construct validity and stability of the scale in patients with bipolar disorder I in the city of Manizales.
Methods: Construct validity was estimated by comparing the measurement in two divergent groups, a control group and a group with bipolar disorder I. It was also compared to a Neuropsychological battery measuring the same scale domains. The correlation between each one of the sub-tests of the scale and stability was evaluated through the reliability test-retest in the group with bipolar disorder I.
Results: The scale showed discriminatory capacity in cognitive functioning between the control group and the group with bipolar disorder I. The correlation with the neuropsychological battery was estimated by the Spearman test showing results between 0.36 and 0.77, and the correlation between each sub-test of the scale showed correlations between 0.39 and 0.72. Test-retest was measured with the intraclass correlation coefficient (ICC) and their values were between 0.77 and 0.91.
Conclusions: The Spanish version of screening scale in the cognitive disorder in psychiatry shows acceptable validity and reliability as a measurement tool in clinical psychiatric practice.
