The present study investigated the relationship of 16 Personality Factor (16 PF) Scores to institutional adjustment, educational level, recidivism, and escapism of 665 prisoners in a maximum security prison. Two phases of data analysis were conducted. Multiple two-tailed Students' t tests resulted in significant differences on all 16 PF Factor Scores between prisoners and Cattell adult norm group. Significant differences were also found between prisoners and Cattell prisoner norms. In phase two, four multiple linear regression models were constructed. Significant 16 PF scales, age, and educational differences were found within the prisoner sample. Possible implications of the use of the 16 PF in regression models in paramorphic clinical prediction programs are discussed.

Assessing offenders' risk of future violent behavior continues to be an important yet controversial role of forensic psychologists. A key debate is the relative effectiveness of assessment methods. Specifically, actuarial methods (see Quinsey et al., 1998 for a review) have been compared and contrasted to clinical and structured clinical methods (see e.g. Hart, 1998; Webster et al., 1997). Proponents of each approach argue for its superiority, yet validity studies have made few formal comparisons. In advancing the available research, the present study examines systematically the type of forensic case (i.e., sexual violence versus nonsexual violence) and type of assessment method (i.e., actuarial, structured clinical, and unstructured clinical). As observed by Borum, Otto, and Golding (1993), forensic decision making can also be influenced by the presence of certain extraneous clinical data. To address these issues, psychologists and doctoral students attending the American Psychology Law Society conference were asked to make several ratings regarding the likelihood of future sexual and nonsexual violence based on data derived from actual defendants with known outcomes. Using a mixed factorial design, each of these assessment methods were investigated for its influence on decision-makers regarding likelihood of future violence and sexually violent predator commitments. Finally, the potentially biasing effects of victim impact statements on resultant decisions were also explored.

The purpose of this study was to develop a prediction model for graduation rate at non-residential research universities. As well, this study investigated, described, and compared the student characteristics of non-residential and residential institutions. Making distinctions between significant predictor variables at non-residential research universities and significant predictor variables at residential institutions was also an aim. The researcher obtained data from the Integrated Postsecondary Data System. Student and institutional variables were analyzed using descriptive statistics, independent samples t-tests, analysis of variance, and regression analyses. Results indicated that student and institutional characteristics can be used to significantly predict graduation rate at nonresidential institutions with student variables yielding greater predictive power than institutional variables. As well, residential status was found to moderate the relationship between undergraduate enrollment and graduation rate. / Includes bibliography. / Dissertation (Ph.D.)--Florida Atlantic University, 2016. / FAU Electronic Theses and Dissertations Collection

This study examines the relationship between exercise adherence and several factors: self-motivation; attitudinal commitment; predisposing, enabling, and reinforcing (PER) factors; and barriers related to exercise. The sample (N=431) consists of employees at Texas Instruments, Incorporated in Dallas, Texas. The sample was placed into six comparison groups: high adherers, low adherers, nonparticipants who exercise, nonparticipants who do not exercise, dropouts who exercise and dropouts who do not exercise. Using a one-way ANOVA, the results show significance (p<.01) among the groups for: self-motivation and barriers. Attitudinal commitment and PER factors did not show significance. The results can be applied to worksite health programs to increase exercise adherence among employee populations.

This research examines the content and process involved in developing criminal profiles. To assess the material typically included in profiles and the way that the conclusions are developed, a qualitative analysis of the content of profiles was undertaken. This included, among other things, the characteristics offered, their prevalence, and the most common characteristics by profiling method. A further quantitative study was undertaken employing Multidimensional Scaling (MDS) which revealed three general themes in the advice given. These included Crime Scene, Internal Offender and Offender Characteristic facets, each of which was comprised of features suggestive of that facet. For example, the Crime Scene facet typically described offender actions and their interpretation at the physical location of the criminal event, such as staging and methods of control.The study employed a sample of 49 profilers reflective of the four main schools of thought; Criminal Investigative Analysis (CIA), Investigative Psychology (IP), Diagnostic Evaluations (DE) and Behavioural Evidence Analysis (BEA). CIA profiles were greatest in number with a sample size of 19. There were 14 BEA profiles and 8 each of DE and IP profiles. Together, there were in excess of 3000 individual variables ranging from age, sex and race to employment, geography, mental illness and risk.Results indicate that the vast majority of profilers employ either research or personal belief in forming their opinions, and that physical evidence is used the least in justifying a profiler’s opinion. However, when considering the individual methods, BEA placed the greatest reliance on physical evidence and its interpretation according with the forensic science philosophy of the method. CIA, the method used by the FBI, produced the most characteristics of the sample at 312 across 19 profiles, followed by BEA at 166 characteristics across 14 profiles. IP and DE profiles, with a sample size of eight each, had 90 and 61 characteristics respectively.Beyond these findings, the implication of the research will be discussed and some future direction for this research and the field in general will be provided. These areas include education, training, the scientific method and professionalisation. This thesis will also canvass the issue of whether profiling is an art or a science with particular reference to the research results and the existing literature that has bothered to address this issue.

There is widespread concern within at least Western cultures of the potential damage that sex offenders may cause to society. The government statistics highlight a frightening pattern of sexual abuse in Australia, with the trend implicating that sexual assault is on the rise and that children are the predominant victims (ABS, 2003b). Specifically, 17,850 reports of sexual assault were recorded in 2002, a 6% increase since 2001. Further to this, there is still no universal agreement as to the extent to which treatment effectively reduces sexual recidivism. Therefore, there is an urgent need for research into this problem behaviour. Research examining the causes of sexual offending has examined a biological hypothesis that sex offenders have functional brain impairment. However, the results of neuropsychological assessments of various sex offender populations are inconsistent and inconclusive. The aim of this study was to investigate the brain function of males convicted and incarcerated for sexual offences against children using neuropsychological assessment. Specifically, it was hypothesised that the sex offenders would show functional impairment in their frontal and temporal lobes. A battery of neuropsychological tests was compiled to assess the functions of these regions including four WAIS-Ill subtests (Arithmetic, Vocabulary, Block Design and Picture Arrangement), Rey Auditory Verbal Learning Test (RAVLT), Rey Complex Figure (RCF), Wisconsin Card Sorting Test (WCST) and the FAS Test. These tests were administered to 25 incarcerated male sex offenders, 25 incarcerated male non-sex offenders and 25 men with no criminal history. Although attempts were made to match these groups on age, level of education and level of intelligence, statistical analyses revealed that there were significant differences between the groups on these variables. These differences were statistically controlled using analyses of covariance (ANCOVAs) and factorial analyses of variance (ANOVA). The results indicated that the sex offenders performed significantly worse than the controls on all neuropsychological tests. However, statistically significant differences were only found between the sex offenders and control group on the immediate recall trials of the RAVLT and RCF. These observed differences did not change when age, level of education and level of intelligence were statistically controlled. It was concluded that there is insufficient evidence from this study to support the hypothesis that sex offenders have functional impairment in their frontal and temporal lobes. However, given the relevance of potential brain impairment to both the biological and social-cognitive perspectives of sexual offending, future research in this field is warranted.

The purpose of this study was to determine the effects of a six-week career planning dropout prevention program on the self-concepts and academic achievement of at-risk middle school students in an inner-city public school environment. The research population consisted of 1,434 students (grades seven, eight and nine) attending an inner city public junior high school in south-central Los Angeles, California. The selection of the research site and sample was based on the assumption that the student population met the criteria and demographic profile of at-risk students: Students are from low-income and/or single parent families; have low achievement scores in reading and mathematics; exhibit a high incidence of truancy, absenteeism and teenage pregnancy; have low career aspirations and plans; and exhibit other related characteristics of at-risk students. The study was conducted from September, 1993 to January, 1994 (fall semester, 1993). All students were selected by random procedure from grades seven, eight and nine. The experimental group consisted of 195 students enrolled in a woodworking class. The control group consisted of 1,239 students who were not enrolled in a woodworking class but were enrolled in other elective classes. The experimental treatment consisted of a six week career planning dropout prevention program. The career planning dropout prevention program was infused into the 20-week woodworking class during the 6th through 12th week, and consisted of seven interrelated topics and lesson plans. The objectives of the study were to research and explore career interests and options, and to construct personal career planning portfolios for students in the experimental group. It was concluded that: a) There were no significant differences between pre and post measures of self-concept in the experimental group, b) There was no significant difference in the pre and post academic achievement scores between the control and experimental groups, c) There was a substantial increase int he academic achievement scores of the experimental group, but this increase did not equal or exceed the alpha value. / Graduation date: 1997
