Reliability, Validity, and Classification Accuracy of a Spanish Translation of a Measure of DSM-IV Diagnostic Criteria for Pathological Gambling

Abstract

The aim of this study was to measure the reliability, validity, and classification accuracy of a Spanish translation of a measure of DSM-IV diagnostic criteria for Pathological Gambling (PG). Participants were 263 male and 23 female patients seeking treatment for PG and a matched non-psychiatric control sample of 259 men and 24 women. A Spanish translation of a 19-item measure of DSM-IV diagnostic criteria for PG (Stinchfield 2003) was administered along with other validity measures. The DSM-IV diagnostic criteria were found to be internally consistent with a coefficient alpha of .95 in the combined sample. Evidence of satisfactory convergent validity included moderate to high correlations with other measures of problem gambling. Using the standard DSM-IV cut-score of five, the ten criteria were found to yield satisfactory classification accuracy results with a high hit rate (.95), high sensitivity (.92), high specificity (.99), low false positive (.01), and low false negative rate (.08). Lowering the cut score to four resulted in modest improvements in classification accuracy and reduced the false negative rate from .08 to .05. The Spanish translation of a measure of DSM-IV diagnostic criteria for PG demonstrated satisfactory psychometric properties and a cut score of four improved diagnostic precision.

Contribution of Illegal Acts to Pathological Gambling Diagnosis: DSM-5 Implications

“…Diagnostic Questionnaire for Pathological Gambling According to DSM-IV Criteria 5 Spanish adaptation was performed by JimenezMurcia et al 4 This 19-item questionnaire assesses the DSM-IV diagnostic criteria for pathological gambling. Internal consistency is 0.81 for the general population, and 0.77 for the gambling treatment samples.…”

“…This change is congruent with studies that have found a cutoff point of 4 criteria to increase the sensitivity in the identification of disordered individuals and the improvement of diagnostic accuracy. [4][5][6] The endorsement of a 4 or more criteria-based threshold significantly improved the estimation of epidemiological indices, with an increase of 5% (from 20.5% to 25.5%) in the identified prevalence of pathological gambling within a clinical sample of French patients seeking treatment for addictive behavior. 7 Finally, the DSM-5 Work Group has considered the recommended elimination of the symptom "illegal acts" as part of the pathological gambling disorder.…”

Sex addiction and gambling disorder: similarities and differences

“…This 19-item questionnaire measures the ten DSM-IV diagnostic criteria for GD [3,47,48]. The tool has demonstrated satisfactory psychometric properties with an internal consistency (measured with Cronbach's alpha) which yielded values of α = 0.81 for the general population and α = 0.77 for a gambling treatment group.…”

“…Convergent validity was estimated with a correlation with the SOGS as r = 0.77 for a general population sample and r = 0.75 for a gambling treatment sample. This scale has been adapted for the Spanish population by Jimenez-Murcia, Stinchfield and colleagues [48], and has demonstrated adequate psychometric properties. Cronbach's alpha in the present sample was high (α = 0.90).…”
