Abstract:
In this study, we examined the validity of the Personality Assessment Inventory Alcohol (ALC) scale in 736 male veterans presenting for formal evaluation of posttraumatic stress disorder (PTSD). The ALC scale exhibited convergence with other measures of alcohol problems, and this convergence was similar for veterans with and without formal PTSD diagnosis. When predicting alcohol consumption via the Alcohol Use Disorders Identification Test (AUDIT), the ALC scale also displayed substantial incremental validity over the effects of demographics and MMPI-2 MacAndrew Alcohol Scale. Using a standard alcohol consumption cut score on the AUDIT, the ALC scale displayed good specificity and (generally) good sensitivity across three common cut scores. PTSD severity did not significantly affect the association between the ALC composite and alcohol consumption via the AUDIT. Taken together, results suggested that the ALC can provide valid assessment of alcohol use among treatment seeking veterans.

The process of oxidation in a chemical reaction is observed in any of the three forms:
02:29Ethers from Alcohols: Alcohol Dehydration and Williamson Ether Synthesis
Ethers can be prepared from organic compounds by various methods. Some of them are discussed below,
Preparation of Ethers by Alcohol Dehydration
In this method, in the presence of protic acids, alcohol dehydrates to produce alkenes and ethers under different conditions. For example, in the presence of sulphuric acid, dehydration of ethanol at 413 K yields ethoxyethane, whereas it yields ethene at 443 K.
02:31Protection of Alcohols
Protection
It defines a protecting group as the masking agent to make the more reactive species inert to a given set of conditions. This concept is depicted via the illustration of liquid flow through different outlets in an assembly of pipes. The analogy helps to understand the role...
01:38Preparation of Alcohols via Substitution Reactions
Alcohols can be synthesized from alkyl halides via nucleophilic substitution reactions. The highly polar carbon-halogen bond in the substrate makes halide a good leaving group. The hydroxide ion or water can act as a nucleophile to take the place of halide and form an alcohol. The substitution reactions occur via two different reaction pathways, SN1 or SN2, depending on the nature of carbon attached to the halide.
Primary alcohols are synthesized from primary alkyl halides, and the...
01:17Esters to Alcohols: Hydride Reductions
Lithium aluminum hydride is a source of hydride ions and functions as a nucleophile. The mechanism proceeds in three steps. Firstly, the nucleophilic hydride ion attacks the carbonyl carbon of the ester to form a tetrahedral intermediate. Subsequently, the carbonyl group re-forms,...
01:08Esters to Alcohols: Grignard Reaction
The reaction requires two equivalents of the Grignard reagent and introduces two identical alkyl groups, derived from the Grignard reagent, bonded to the hydroxyl-bearing carbon of the alcohol.
The reaction follows the typical nucleophilic acyl substitution mechanism. The Grignard...
