Abstract: In an important embodiment, the present invention concerns a method for diagnosing and detecting compulsive disorder susceptibility of an individual. The method comprises initially obtaining a DNA sample of said individual and then determining the presence or absence of particular human D.sub.2 receptor gene alleles in said sample. Detection of said alleles in the sample are indicative of predilection to compulsive disorder. A most preferred embodiment is to detect predisposition to impulsive, addictive, and compulsive disorders such as, but not limited to, alcoholism, obesity, smoking, polysubstance abuse and drug addiction, particularly because said alleles have been found to be present in a majority of individuals clinically diagnosed with these compulsive disorders. The human D.sub.2 receptor gene A1, B1, and .sup.In6-Ex7 haplotype I alleles are most preferably detected in said sample.

Abstract: A child's booster seat comprises an inflatable seat member having a primary base chamber, two opposed side chambers and a back chamber upstanding from the base chamber. An inflatable secondary base chamber is located below the primary base chamber to support the seat member thereon, the secondary base chamber being selectively inflatable to determine the height of the seat member relative thereto, restraining means being provided for retaining a child in the seat member, and securing means being provided for attaching the booster seat to a supporting chair.
