This study examined the effectiveness of the MMPI in identifying juvenile sex offenders. This study examined the hypothesis that previously identified subscales of the MMPI (i.e., Toobert et al. (1959) Pe scale and Dolan (1986) Ic scale) could be used in discriminating juvenile sex offenders (n=l 02) (and subgroups of juvenile sex offenders i.e., pedophiles n=79, and incest perpetrators n=41) from a control group of 40 juvenile offenders who had been adjudicated for non-sex related crimes. The study yielded results which indicate that the Pe subscale was not effective in discriminating pedophiles from non-pedophile sex offenders or from the control group. The results also indicated that the Ic subscale was not effective in discriminating incest perpetrators from non-incest sex offenders or the control group. The results from the data also indicate that the control group appeared more pathological than the sex offender group, based on their respective MMPI profiles. In addition, in comparison with previous research on adult sex offenders, there appears to be differences between adult sex offenders and juvenile sex offenders when comparing mean two point code scores. Problems in defining subgroups were discussed. A lack of research in the area of juvenile sex offenders was identified and a strong recommendation for further research in this area was made.

Beck's cognitive diathesis-stress theory has generated much research into the etiology of depression. Central to the theory are depressogenic schemata that interact with stressors, resulting in increases in depressive symptomatology. These schemata are commonly assessed using the Dysfunctional Attitudes Scale (DAS). Importantly, the DAS was not designed for use in children---it has been validated with adults and contains advanced language. Thus, the Child and Adolescent Dysfunctional Attitudes Scale (CADAS) was developed. / Study 1 sought to psychometrically validate the CADAS. 453 children completed the CADAS item pool and measures assessing divergent validity. The CADAS was readministered 3 weeks later. Items were retained based on item-total correlations, internal consistency, and factor analyses. The finalized CADAS is a 22-item self-report measure with a unidimensional factor structure and sound psychometric properties. / Study 2 tested Beck's theory using the CADAS to assess depressogenic schemata as a vulnerability factor for depression. An independent sample of 241 children completed the CADAS and a measure of depression one week before receiving school report cards (Time 1). The morning after receiving reports (Time 2), stress was assessed by obtaining parents' reactions to reports, and with an index of children's subjective acceptable grades compared to actual grades. Five days later (Time 3), depression was reassessed. / As hypothesized, regression analyses collapsing across age revealed that Time 1 CADAS interacted with Time 2 parental stress to predict changes in depression from Times 1 to 3. High-CADAS children showed greater increases in depression relative to low-CADAS children when facing the stress of parental anger and disappointment regarding their grades. Consistent with cognitive-developmental theory, planned supplemental analyses indicated that the CADAS x stress interaction predicted depressive changes only in older, formal-operational children. The relationship between the CADAS x stress interaction and depressive changes was mediated by negative views of the self, but not by views of the world or of the future. / This work yields a measure of depressogenic schemata in school-aged children that further contributes to understanding their etiology of depression. These schemata, together with negative views of oneself, may be important targets for modification in the cognitive therapy of childhood depression.

Federal and state laws have mandated preschool educational screenings. However, these laws only specify that a screening measure must be incorporated in the school's procedures. The laws do not state what this screening measure should be or how it should be used. For example, Public Law 94-142 established that a school should focus on early identification and intervention of children with special needs, but did not specify how to identify these students. As a result, reliable, valid screening measures are needed. A review of the current literature indicates that there are numerous screening measures available, but there is conflicting evidence regarding how these measures should be used and their predictive validity. The purpose of this current study is to evaluate the ability of a school corporation's local kindergarten screening measure, known as SEEK, to predict school achievement by the end of third grade, and special education placement, Title I support services, and gifted services by the end of fifth grade for both Amish and English speaking students. School achievement was measured by the student's performance on the third grade ISTEP. Archival educational data was collected for 333 children who participated in SEEK in 1997 and 1998, and then later took the third grade ISTEP. Results of the multiple regression analyses revealed that the overall composite score of the SEEK significantly predicted third grade ISTEP scores, special education placement, Title I support services, and gifted support services for both Amish and English students. However, the significance of the different components of SEEK to predict ISTEP scores varied depending on the area of ISTEP measured. In addition, the sensory and the behavior components did not significantly predict variation on ISTEP scores for either.language or math. Overall, these findings help validate the predictive validity of using the overall SEEK score and the usefulness of kindergarten screening. In addition, this study has implications in developing preventative approaches to benefit students who may be likely to experience learning difficulties at school. A discussion of the limitations as well as the usefulness of this study is presented along with directions for future kindergarten screening research. / Department of Educational Psychology

The present study attempts to further define the neuropsychological characteristics associated with mild, moderate, and severe closed head injuries (CHI). The Dean-Woodcock Neuropsychological Assessment System (D-WNAS), a new neuropsychological battery, was administered to 119 CHI patients. The scores of the cognitive portion of the D-WNAS were then analyzed via cluster analysis in an attempt to further delineate neuropsychological impairment into more specific classifications occurring within types of brain trauma.Results suggested that the cognitive portion of the D-WNAS was effective in separating 4 subtypes within CHI, which are best interpreted as "profiles" or characteristics associated with "levels" of impairment. These levels of impairment were characterized by distinctly different subtest profiles, and were labeled as mild/high functioning, mild, moderate, and severe. The highest performing group, mild/high functioning, showed no neuropsychological deficits. The most severely impaired group was characterized by many deficits in short-term memory, visual stimuli, new learning, processing speed, visual-spatial abilities, abstract reasoning, attention/concentration, and remote memory tasks. A multivariate analysis showed that educational level was significant in differentiating between the subtypes and suggested that, depending on the severity of injury, educational level might also protect individuals from obtaining a poorer prognosis.From this investigation, the cognitive portion of the D-WNAS appears to offer valuable utility in identifying CHI patients and in further classifying their varied neuropsychological characteristics. Implications for diagnosing and differentiating between different levels or profiles of CHI was discussed. / Department of Educational Psychology

This study was designed to determine the factorial validity of specific components of the Reitan-Indiana Neuropsychological Battery with a learning disabled population. Scores of 42 children, 38 males, 4 females, ages 6.2 to 8.8 years were compiled on specific tests of the Reitan-Indiana. Principal component factoring of the original correlation matrix was followed by principal factoring, using a 4 factor solution; varimax rotation with six iterations produced the desired reduction of the correlation matrix; four factors emerged for the learning disabled population, which accounted for 53% of the variance: verbal intelligence, psychomotor speed, achievement, and memory. The factor structure that emerged was not consistent with the surface factors of the battery as conceptualized by its author suggesting that this battery may lack construct validity when used with a learning disabled population.

The purpose of this study was to explore the efficacy of juvenile offender assessments. Data from 104 juvenile offender assessments were analyzed and followed up with placement, subsequent offending, and outcome data from the juvenile and adult systems. Constructs consistently assessed included intellectual functioning, academic achievement, and personality functioning; however, under-diagnosis of intellectual deficits, learning disabilities, and personality disorders was found. Results indicated the assessment of family functioning, substance use, and social functioning should be included in comprehensive assessments, as they may result in alternative placement and treatment options of benefit to the juvenile offender. A juvenile offender typology proposed by DiCataldo and Grisso (1995) was successfully utilized and proved predictive of recidivism, future harm to others, and outcome.

The purpose of the present study was to compare their (avoidance contingency and positive-reinforcement contingency) relative effectiveness in producing a desired behavior.

The purpose of this study was to find if memory load significantly affects the performance of the subjects in the before condition of a before versus after technique experiment. In order to accomplish this the alternatives were presented either before or after the stimulus, with the alternatives and stimuli being either of high-complexity or low-complexity.
