The purpose of this study was to describe the development and initial validation of an instrument to identify women who are alcohol dependent. The instrument is called the Identification of Alcohol Dependence in Women (IADW) Scale. The following research questions were addressed: 1. To what degree can the instrument demonstrate validity for the identification of women who are alcohol dependent? A. To what degree are the items representative of the model? B. What is the factor structure of the IADW Scale? C. To what degree do the items discriminate between alcohol and non-alcohol dependent women? D. What is the association between responses on the IADW Scale and the responses on the Crowne Marlowe Social Desirability Scale? 2. To what degree can the instrument demonstrate reliability for the identification of women who are alcohol dependent? A. What is the internal consistency reliability estimated from the Cronbach alpha? B. What is the reliability estimated by a test/retest procedure? The rationale and methods for developing this instrument were delineated. The items were related to the theoretical structure of the model which depicted dependence as physiological, psychological and sociological outcomes of continued use of alcohol. A pilot test of the instrument on 28 alcohol and 28 non-alcohol dependent women was completed. The criteria for eligibility to the alcohol dependent group was a positive score of three or more items on the SMAST, involvement in alcohol treatment and answering that problems resulted from the use of alcohol. Based on these findings, the field study generated data on 51 items to demonstrate evidence of the degree of validity and reliability of the IADW Scale. The field study was conducted on 151 alcohol and 150 non-alcohol dependent women. Statistical analyses included discriminant and factor analyses, Pearson correlations of the IADW Scale scores with social desirability scores and estimations of stability and internal consistency reliability. Three factors were generated; the psychological (factor one) and physiological (factor two) items unrelated to the use of alcohol; sociological items unrelated to the use of alcohol did not emerge. Instead, a factor (factor three) emerged which consisted of physiological, psychological and sociological items which were related to the use of alcohol. Discriminant analysis procedures correctly classified 95 percent of subjects into either the alcohol or the non-alcohol dependent groups. Subjects responded in a socially desirable manner to psychological items unrelated to the use of alcohol but responded in a less socially desirable manner to items related to the use of alcohol. Reliability estimates on the IADW Scale and its subscales were above .95. The IADW Scale in its present form shows promising evidence of validity as evidenced by factor and discriminant analyses.
