Increased consultation opportunities for school psychologists: A service delivery model

A model of delivery of services that enables school psychologists to meet testing demands while initiating a broad range of consultative services is described. Requirements of the model include: (a) having funds available for contract testing, (b) having conferences with teachers prior to formal referral of children, and (c) having qualified contract evaluators available. Benefits, as well as obstacles to be expected in implementing the model, are discussed.

Juvenile sex offenders: development and correction

This paper addresses the developmental nature of sexually abusive behaviors as they apply to juvenile male sexual offenders. Socialization and sexual victimization are discussed. Three case histories elucidate and support the discussion of the development of victim offending. Significant treatment issues of juvenile male sexual offenders center around the sexual assault cycle which provides a framework for sexual offenders to conceptualize and understand the cognitive, behavioral, psychological, and situational factors which have resulted in their offense(s). Although sexual offenders and sexual offenses are each unique, the sexual assault cycle offers a means of addressing essential commonalities in the treatment of juvenile sexual offenders. Sexual offender specific treatment is viewed as essential for decreasing the risk of further sexual offenses, and thus decreasing the incidence of sexual victimization.     

Resilience in child maltreatment victims: a conceptual exploration

While many child maltreatment victims suffer serious negative emotional sequelae, others do surprisingly well. Resilience in children is a relative concept which can change over time and is affected by environment and genetics. Resilience is fostered by protective factors which ameliorate or alter a child's response to the hazards of maltreatment that usually predispose to maladaptive outcome. Personal characteristics or skills that may foster resilience include (1) rapid responsivity to danger; (2) precocious maturity; (3) dissociation of affect; (4) information seeking; (5) formation and utilization of relationships for survival; (6) positive projective anticipation; (7) decisive risk taking; (8) the conviction of being loved; (9) idealization of an aggressor's competence; (10) cognitive restructuring of painful experiences; (11) altruism; and (12) optimism and hope. There are also generic life circumstances, such as having access to good health, educational, and social welfare services, that foster resilience in children regardless of the specific nature of the stressor. Additionally, there may be abuse-specific protective factors in the environment. Examples might include the quick and full acknowledgment of an offender regarding abuse, or timeliness and permanence of legal actions affecting a child's custody. The life stories of three well-known survivors of various forms of child maltreatment illustrate how protective factors contribute to resilience. A caution is noted regarding how personal characteristics developed for survival may become maladaptive if overused and/or not given up when the stressor no longer exists. Characterological problems are most likely to develop when a child's life circumstances fail to change and the environment never becomes secure.     

Mental health care for foster children in California

This paper reports on a study conducted to assess the health care needs of foster children in California. To evaluate foster children's mental health problems and the services provided to meet them, 154 program administrators, social workers, foster parents, and health care providers were interviewed in 14 counties. Foster parents and social workers were interviewed in groups, and foster parents and administrators also completed questionnaires. We found that although all counties care immediately for children who are injured, abused, or ill, only one county performs routine mental health evaluations of all children, and in most counties less than a third of children ever receive such evaluations. Informants identified mental health problems as more severe than medical problems in this population, and they identified four major barriers to access to appropriate therapy. Recommendations are that all children should receive comprehensive mental health evaluations, and procedures for immediate and ongoing care with consistent providers who are sensitive to foster children's needs should be included in case management plans, and covered by improved payment mechanisms. Additionally, communication, coordination and joint planning should be instituted among relevant agencies to address foster children's needs, and increased resources and training should be directed towards social service agencies and foster parents.     

Behavioral medicine and health psychology in a changing world

Despite long-established roots in experimental psychophysiology and psychosomatic medicine, behavioral medicine and health psychology have only recently emerged as recognized, highly visible disciplines within medicine and the behavioral sciences. The rapid development of these fields has resulted partly from important scientific advances in the biomedical and behavioral sciences and partly from changing societal concerns and values. The latter include a greater preoccupation with individual self-expression and self-fulfillment, a decline in respect for authority per se, and an increased skepticism about social institutions. Coupled with these changes has been an increasing desire to take responsibility for one's own life and, in matters of health, of one's own body. The ways in which scientific advances and social changes have influenced the shape of contemporary behavioral medicine and health psychology are explored with the aid of two illustrations: the growth of a developmental perspective in behavioral medicine and health psychology; and work and health, including the effects of job stress and unemployment. Finally, the author stresses the need for a greater sense of community and concern for others, if we are to succeed in creating a growth-enhancing, health-producing climate for society as a whole and for each of us as individuals.     

DNA microarray wet lab simulation brings genomics into the high school curriculum

We have developed a wet lab DNA microarray simulation as part of a complete DNA microarray module for high school students. The wet lab simulation has been field tested with high school students in Illinois and Maryland as well as in workshops with high school teachers from across the nation. Instead of using DNA, our simulation is based on pH indicators, which offer many ideal teaching characteristics. The simulation requires no specialized equipment, is very inexpensive, is very reliable, and takes very little preparation time. Student and teacher assessment data indicate the simulation is popular with both groups, and students show significant learning gains. We include many resources with this publication, including all prelab introductory materials (e.g., a paper microarray activity), the student handouts, teachers notes, and pre- and postassessment tools. We did not test the simulation on other student populations, but based on teacher feedback, the simulation also may fit well in community college and in introductory and nonmajors' college biology curricula.
