The effects of applied tension on symptoms in French-speaking blood donors: a randomized trial.

Blood-donation-related symptoms such as dizziness and weakness discourage people from participating in this important health-related activity. Four hundred sixty-seven young adult, French-speaking blood donors were randomly assigned to (a) a condition in which they learned a possible preventive technique called applied tension and were asked to practice it from the time they got on the donation chair until they were just about to get up, (b) a placebo condition in which they learned applied tension and were asked to practice it from the time they got on the chair until the insertion of the donation needle, or (c) a no-treatment control condition. Donors assigned to the treatment condition reported significantly fewer blood-donation-related symptoms than did donors assigned to the other conditions and rated their likelihood of returning to give blood again as greater than did those in the no treatment condition. Among donors whose chairs were not reclined, participants in the treatment condition had significantly smaller heart rate reactions to blood donation than did those in the other conditions.     

A Comparative Review of Current Practices in Personality Assessment Norming

Because consequential personnel decisions are often made by comparing an individual against a norm group, having accurate and representative norms is as important as having sound selection procedures. Existing standards provide specific guidance on selection procedures, but are less clear on norms. To fill this gap and define best practices, we (a) review existing literature and guidelines; (b) review current applied practices using 30 personality assessments offered in the United States, United Kingdom, and Canada; and (c) provide recommendations for strengthening existing guidelines and helping publishers develop, present, and apply norms for personality assessments.     

Bioelectrical potentials of Philodendron cordatum: a new method for investigation of behavior in plants

We explored the prospect of using the bioelectrical potentiaLs of Philodendron cordatum as a new method for studying the behavior of plants. The bioelectrical potentials were recorded from equipment typically associated with EEG recordings. Plants were exposed to a 6-hr. training period of light only, dark only, or alternating 1-min. periods of light/dark. Following training, all plants were exposed to a 10-min. testing period in darkness during which bioelectrical potentials were recorded. Power of the bioelectric potentials was compared between groups of plants for frequencies between 0.1 and 10.0 Hz. Significant main effects of group and frequency were found, raising questions about the possibility of "learning" in P. cordatum.     

Assessment of quality of life in a multicultural cancer patient population

Quality of life (QOL) is increasingly assessed in cancer patients. In this article, the authors examined the psychometric performance of a commonly used QOL questionnaire, the Quality of Life Questionnaire--Cancer 30 (QLQ-C30; N. K. Aaronson et al., 1993), in multiethnic cancer patients. Content validation studies in patients and clinicians identified possible new items. Multiple-group confirmatory factor analysis supported equivalent structure across ethnic groups (Caucasians and Asian/Pacific Islanders [APIs]). A higher order QOL factor appeared to directly affect functioning scales and symptom count. Exploratory factor analysis examined effects of new items. Ten factors were extracted, 6 consistent with the original instrument and 4 reflecting potentially new aspects of QOL: Positive Social Support, Coping, Existential Well-Being, and Sexuality/Intimacy. The QLQ-C30 appears appropriate for use in API cancer patients. Further work needs to ensure that it includes all important domains.     

Development of an ethanol model using social insects: II. Effect of Antabuse on consumatory responses and learned behavior of the honey bee (Apis mellifera L.)

The ability of Antabuse (disulfiram) to influence ethanol consumption and learning in harnessed honey bees was investigated. In the first series of experiments a factorial design was used with 5 levels of ethanol concentration (0%, 1%, 5%, 10%, 20%), 4 doses of Antabuse (0, 37 microg/g, 3.7 microg/g, .37 microg/g), and 2 testing intervals (1 min., 10 min.). Animals were fed a single 1 microl dose of Antabuse and contact time with an ethanol solution measured. A second series of experiments investigated the influence of Antabuse on the formation of Pavlovian conditioning of the proboscis extension reflex. A factorial design was used with two levels of training (paired, unpaired), three levels of ethanol (0%, 1%, 5%), and 2 levels of pretreatment (distilled water, 3.7 microg/g). Analysis of the consumption experiments indicate that pretreatment with Antabuse reduces ethanol intake, although there was substantial variability. The findings of the Pavlovian experiments suggest that pretreatment with Antabuse significantly reduced responding to a CS signaling the availability of ethanol.     

Cardiac change scale: A brief, self-report research measure

The purpose of this study was to develop and evaluate a brief, self-report measure of the degree of perceived change resulting from cardiac illness. Life change has been widely recognized as stressful, but it is usually assessed with generic checklists of events which have been found wanting in terms of reliability and validity. The proposed measure was designed to assess life change in factors commonly reported to be important in recovery from cardiac illness. The Cardiac Change Scale was found to have very good internal consistency and acceptable test-retest reliability. The construct and criterion validity of the Cardiac Change Scale were supported.     

The Passage of Counselor Legislation in the 1991 Arkansas State Legislature

In the summer of 1990, the Board of Directors of the Arkansas Associationfor Counseling, Guidance, and Development (now the Arkansas Counseling Association) committed to proposing a legislative package to the 1991 Arkansas General Assembly that included bills to grant privileged communication to school counselors; a third-party payment bill for licensed professional counselors; and a resolution calling for the reduction of noncounseling-related duties for school counselors. This article details the legislative efforts of the Arkansas Association for Counseling, Guidance, and Development in the 1991 Arkansas General Assembly and provides insight for other American Association for Counseling and Development (now the American Counseling Association) state affiliates in planning and implementing a successful legislative program.     

The bits and bytes of computer/internet addiction: A factor analytic approach

A factor analytic approach was used to explore possible constructs underlying so-called computer/Internet addiction. A 94-item survey was developed, from which two major and two minor factors were derived. Factor 1 focused on problematic computer-related behaviors in heavy users of the Internet, whereas Factor 2 focused on the usefulness and general purpose nature of computers and the Internet. Factor 3 isolated a combination of use of the Internet for sexual gratification and shyness/introversion, and Factor 4 focused on an absence of problems related to Internet use that were coupled with a mild aversion or a disinterest in this technology. These data support the notion that some individuals have a mixture of obsessive-like characteristics related specifically to their computer/Internet use but that, not surprisingly, they also exhibit a preference for on-line, rather than in-person, interactions.
