Measurement of ethical behavior in leisure among high- and low-risk adolescents.

Based on Aristotelian ethics, an "Adolescent Ethical Behavior in Leisure Scale" (AEBLS) was developed. Sixty-two items were created and reviewed by a panel of experts for content-related evidence of validity. Two validity studies were then conducted. In Study 1, data from 419 high- and low-risk adolescents were used to examine correlations between the AEBLS scores and measures of substance use, school bonding, and dispositional leisure boredom. All hypotheses about relations between these variables and the AEBLS were supported. In Study 2, an experiment was conducted to assess construct-related evidence of validity. Seventy-one adolescents completed the AEBLS and evaluated images of sensory and cortical recreation activities to which they were exposed. Consistent with the hypotheses, significant positive correlations were found between the AEBLS and evaluation of cortical activities, and significant negative correlations were found between the AEBLS and evaluation of sensory activities. Results support the use of AEBLS scores to discriminate between ethical leisure behaviors of high- and low-risk adolescents.

Development of a tool to assess suicide risk factors in urban adolescents.

Dramatic increases in the adolescent suicide rate over the past three decades have underscored the need for risk-assessment tools. The tools that do exist are oriented to older populations and their application to adolescents is questionable. A project was initiated at the University of Utah's Health Education Department to develop a pilot instrument to examine the differences between adolescents who have attempted suicide and other teenagers. Eighty-two subjects between the ages of 14 and 19 participated in the test of this instrument. Twenty-five subjects were identified by a physician or psychologist as having failed in a sincere suicide attempt within the previous 18 months. Fifty-seven nonsuicide attempters with similar demographic profiles served as a comparison group. An 86-item questionnaire was administered to both groups. Questions were generated from a review of the literature of the past three decades for problems associated with suicide in this population. Questions were sorted into three domains (family environment, social environment, and self-perceptions), with each domain having several subdomains. Statistical analysis revealed significant differences for each of the three domains and on 55 of 86 questions. The results were used to create a streamlined instrument for assessing suicide risk that can be administered in 20 minutes.

Facilitating "flow" through therapeutic recreation services.

The rationale and means for facilitating flow for disabled individuals in situational and community recreation settings is discussed. The flow model and arousal model are discussed and implications of leadership aimed at facilitating flow are delineated. Specific principles discussed are: attracting attention, arranging complexity to provide optimal challenge, narrowing the stimulus field, minimizing extrinsic rewards, arranging for immediate feedback, and minimizing the individual's awareness of and focusing on the outcomes of involvements.
