Evaluating the relative effectiveness of three aversion therapies designed to reduce craving among cocaine abusers

Crack cocaine use and dependence has been steadily increasing since the mid‐1980s. Treatment approaches vary from simple psychotherapy to intensive medication regimens. One clear phenomenon that has been implicated in the continued use and abuse of crack cocaine is craving. Craving is believed to be a response that has been conditioned with previous drug using episodes, and is elicited by environmental cues. The current study investigated the use of three aversion therapies (chemical, covert sensitization, and faradic) designed to eliminate craving for cocaine. Seventy subjects were randomly assigned to one of three aversion treatments or a relaxation control condition. Results indicate that aversion therapy reduces crack cocaine craving. The use of aversion therapy as an adjunct to traditional treatment programs for reducing craving is discussed. Copyright © 2004 John Wiley & Sons, Ltd.     

Personality traits and the development of nicotine, alcohol, and illicit drug disorders: prospective links from adolescence to young adulthood

The personality traits constraint (CN) and negative emotionality (NE) have been more (CN) or less (NE) consistently associated with alcoholism. The authors examined the association of personality at age 17 with timing of onset and with prospective prediction of nicotine, alcohol, and illicit drug disorders 3 years later in a twin sample (569 females; 432 males). Earlier onset of alcohol and drug disorders (by age 17) was related to significantly lower CN compared with later onsets (by age 20); high NE was related to either onset. NE, as well as CN, uniquely predicted new onsets of all 3 types of substance use disorders by follow-up, with preexisting substance disorders taken into account. Personality traits confer generalized risk for developing any substance disorder, though some traits are more strongly linked with some substance disorders than with others.     

Improving the Transportability of CBT for Internalizing Disorders in Children

Research provides strong support for the efficacy and effectiveness of cognitive behavioral therapy (CBT) for the treatment of childhood internalizing disorders. Given evidence for limited dissemination and implementation of CBT outside of academic settings, efforts are underway to improve its transportability so that more children with mental health needs may benefit from treatment. Creative modifications to existing treatments aim to deliver CBT for anxiety disorders and depression in a more transportable format. Notable progress has been made within the areas of computerized CBT, camp-based CBT, school-based CBT, and CBT delivered through primary care settings. These approaches are discussed within the context of key elements of transportability that are particularly germane to the dissemination and implementation of child treatments.     

What Does it Take to Break the Silence in Teams: Authentic Leadership and/or Proactive Followership?

Leadership may help break the silence in teams, but this may not be equally true for all employees. Using behavioral plasticity theory, we propose that authentic leadership—a set of leadership behaviors through which leaders enact their true selves—reduces silence and motivates speaking up in employees low on proactive personality, but hardly affects employees who are proactive by nature, because proactive employees are less susceptible to social influences. Using data from 223 employees (nested in 45 work teams), we indeed find authentic leadership to reduce silence in employees with less proactive personalities, but not in more proactive employees. We discuss theoretical and practical implications for silence and authentic leadership.     

A Comparison of the Effects of Prejob Training and Job Experience on Nonprofessional Telephone Crisis Counselors

ABSTRACT: This study, carried out in a telephone crisis intervention program in which nonprofessional volunteer counselors received 55 hours of prejob training, isolates the effects of prejob training and on-the-job experience. Participants in the study were evaluated on several parameters including knowledge, counseling skills, acceptance of others, and dogmatism. Three groups of volunteers were measured: group 1—measured immediately before and after prejob training, group 2—measured just after prejob training, and group 3—measured after five months of telephone counseling experience. Results indicate that counselor skills and knowledge significantly increased with prejob training, but did not show further improvement as a result of five months of experience. Attitudes such as acceptance of others and dogmatism did not change either as a result of training or experience. Dogmatism was found to be inversely related to both counselor skill and knowledge.     

LINGUISTIC AWARENESS AND EARLY READING

Children from five Year 1 classes (n = 129) were assessed with the Concepts About Print (CAP) Test and standardized reading measures. A principal component score derived from the South‐gate Word Selection Test and the ACER Primary Reading Survey Test Level AA was used to derive three groups of readers (poor, average, good). A factor analysis of the CAP indicated four clusters of items. Three of these, letter‐word concepts (.77), print direction concepts (.39) and age (.32), were found to load on a significant discriminant function separating the three groups. Univariate procedures revealed that print direction concepts, letter‐word concepts and advanced print concepts significantly separated the three groups of readers but book orientation did not. Results were discussed in relation to the validity and reliability of the CAP, the relevance of linguistic awareness skills to early reading and the need to tie instruction to concept learning.
