The ability to make precise distinctions among related personality constructs helps clarify theory and increases the utility of clinical assessment. In three studies, the authors evaluated the validity of distinctions among four impulsivity-like traits: sensation seeking, lack of planning, lack of persistence, and urgency (acting rashly when distressed).(More)
The empirical short-form literature has been characterized by overly optimistic views of the transfer of validity from parent form to short form and by the weak application of psychometric principles in validating short forms. Reviewers have thus opposed constructing short forms altogether, implying researchers are succumbing to an inappropriate temptation(More)
Renal solitary fibrous tumors (SFTs) have been reported infrequently. We report a 76-year-old man with a left renal mass that had previously been shown radiographically to be stable, but was now growing. Grossly, the mass measured 12 cm, was poorly circumscribed, and invaded beyond the renal capsule. Approximately 10% of the neoplasm consisted of(More)
PURPOSE The middle school years are peak years for substance use initiation. The current study assessed the impact of peer influence on both initiation and escalation of cigarette, alcohol, and marijuana use among sixth, seventh, and eighth graders. METHODS Youth (n = 974; 45% male) were surveyed twice over an academic year and reported on their personal(More)
In this study the authors tested the acquired preparedness model of problem drinking, which holds that trait disinhibition, defined as neurotic extraversion by C. M. Patterson and J. P. Newman (1993), leads to the biased formation of positive over negative alcohol expectancies. Positive expectancies thus mediate disinhibition's influence on drinking. The(More)
The goal of the present studies was to construct and validate a short form of the 50-item Smoking Consequences Questionnaire (SCQ; T.H. Brandon & T. B. Baker, 1991), a measure of smoking outcome expectancies. In Study 1, a 21-item short form (S-SCQ) was derived from a sample of 107 young adults previously treated for substance abuse. In Study 2, the measure(More)
Evidence has accumulated that nonsteroidal anti-inflammatory drugs (NSAIDs) cause clinically important gastroduodenal ulcers. The pathogenesis, which involves the impairment of mucosal resistance to injury in an acid-peptic environment, is multifactorial and controversial. Ulcers caused by NSAIDs can occur either in mucosa inflamed because of infection with(More)
Experimental research and popular belief suggest that, among its many effects, alcohol consumption reduces tension and facilitates aggression. Such observations could result from direct, pharmacological effects of alcohol on neural control of behavior but also may be accounted for by positing that drinking behavior activates mental representations of(More)
Researchers have found that, compared to European Americans, African Americans report later initiation of drinking, lower rates of use, and lower levels of use across almost all age groups. Nevertheless, African Americans also have higher levels of alcohol problems than European Americans. After reviewing current data regarding these trends, we provide a(More)
An epithelial debridement wound, as a stimulus to the cornea, causes conjunctival goblet cell mucous secretion in that eye. To determine if this stimulation of secretion is neurally mediated, rats were anesthetized and the local anesthetic lidocaine (1%) or buffer alone was administered topically and/or subconjunctivally for 15 min. A corneal epithelial(More)
