This study was a concurrent validation of a paper and pencil test battery used at a national trucking company. Forty-eight driver managers were rated by their immediate supervisors with the performance appraisal covering 12 dimensions of job behavior that was developed by the experimenter. The driver managers were also administered the Wesman Personnel Classification Test, the Watson-Glaser Critical Thinking Appraisal, and the California Psychological Inventory (CPI). A biographical information blank was also developed and validated. Most validity correlations were nonsignificant, with the exception of the Dominance scale r = .25 (p < .05), the Self-control scale r = -.25 (p < .05), the Communanlity scale r = .29 (p < .05), and the Flexibility scale r = -.39 (p < .05), with overall performance.

Self-concept has been defined as being both contextual and multidimensional, varying with different situations and states of being. In this light, the Ecological Q-Sort was developed to measure the varying nature of self-concept in older persons. The purpose of this study is to determine what contextual selves are represented within the framework of the Ecological Q-Sort. The cards of the test were rated and Ward's Hierarchical Clustering technique was utilized to categorize the cards along two dimensional rating factors. Statistical analysis revealed that social, productive, physical, play, active, assertive, and nurturing selves are represented .by the instrument. Those selves are measured by the Loneliness/Sociability, Productive/Relaxation, Vitality/Instability, Initiative/Inefficacy, Confidence/ Uncertainty, and Nurturing/Loss categories.

The development of a standardized assessment can, in general, be broken into multiple stages. In the first, items to be used in the assessment are generated according to the skills and abilities that are to be assessed and the needs of the developers. These items are then, ideally, tested in the field on members of the population for which the assessment is intended. Item Response Theory (IRT) analysis is used to reveal items in the item pool which are unusable due to measurement error, redundancy in the level of item difficulty, or bias. More potential items may be generated and tested until there is a set of valid items with which the developers can move forward. The present study focused on the steps of item tryout and analysis for the establishment of demonstrable item-level validity. Fifty-one potential test items were analyzed for a version of the Shirts and Shoes Test (Plante & Vance, 2012) for 6-year-olds. A total of 23 items were discarded due to error in one or more of the measures mentioned above, and one item was discarded due to its low difficulty. The remaining 27 items were deemed suitable for the 6-year-old population.

Attention Deficit/Hyperactivity Disorder (AD/HD) is not a new phenomenon. Researchers have studied children with restless, inattentive and impulsive types of behaviours for over one hundred years. Although the primary distress of AD/HD falls mainly on the child’s shoulders, all family members experience the disorder’s negative effects. While the challenges that families have to face are many, families seem to have the ability to “bounce back” (i.e., they have resilience). There has been limited research to date focusing on the resiliency of families living with children diagnosed with AD/HD. Research on the construct of resilience, and more specifically, family resilience has surged in recent times. However, South African research on family resilience is limited. This study aimed to explore and describe the factors that facilitate adjustment and adaptation in families after a child has been clinically diagnosed with AD/HD. The Resiliency Model of Family Stress, Adjustment and Adaptation, developed by McCubbin and McCubbin (2001) served as a framework to conceptualize the families’ adjustment and adaptation processes. Non-probability purposive sampling was used in order to gain participants for the study. Twenty-two families participated in this study, providing a total of 44 participants. Participants consisted of the caregivers of a family living with a child diagnosed with AD/HD, between the ages of seven and 12. The study was triangular in nature, with an exploratory, descriptive approach. A biographical questionnaire with an open-ended question was used in conjunction with seven other questionnaires to gather data. Descriptive statistics were used to describe the biographical information. Quantitative data were analyzed by means of correlation and regression analysis, and content analysis was used to analyze the qualitative data obtained from the biographical questionnaire. The results of the quantitative analysis indicated six significant positive correlations with the FACI8. These variables were relative and friend support, social support, problem solving and behavioural strategies, family hardiness, family problem-solving communication and family time and routines. The results of the qualitative analysis revealed that social support, adherence to a treatment regime, information and knowledge about AD/HD, a supportive family unit, the caregiver’s acceptance of the disorder as well as communication were the most important strength factors identified. The findings of the research could assist parents in managing their children diagnosed with AD/HD more effectively and has helped create further insight into what resiliency areas they could improve upon. Furthermore, this study could be used as a stepping stone for future research on resilience in families living with a pervasive psychological disorder and will contribute to the broader context of family resilience research in the South African context.

The ability of several psychometric instruments to differentiate between criminal and non-criminal subjects was investigated. The subjects in the study consisted of fifty male individuals between the ages of 18 and 55, half of which had been convicted of one crime and half of which had no history of criminal activity. The tests administered consisted of the Psychopathic Deviation Scale from the Minnesota Multiphasic Personality Inventory (MMPI), the Psychopathic Deviation Scale of the Clinical Analysis Questionnaire, and two tests designed by the author. The author's tests consisted of the Test of Criminal Cognitions which evaluated antisocial thought patterns and cognitive flexibility, and the Social Semantics Test which assessed individual role definitions. The Test of Criminal Cognitions was administered as a part of a structured interview, and all other scales were administered in a paper and pencil format. The results indicated that the Psychopathic Deviation Scale of the MMPI, and a portion of both the Test of Criminal Cognitions and the Social Semantics Scales differentiated between the groups at the .05 level or better. These findings indicated that criminals tend to be significantly less flexible in their thought and tend to view others in a much more narcissistic manner than non-criminals. The results also indicated that these tests can be utilized to discriminate between criminals and non-criminals. It was additionally noted that the Psychopathic Deviation Scale of the Clinical Analysis Questionnaire did not consistently differentiate between the groups and should not be considered a valid instrument for discriminating between these groups.

The purpose of this study was to: (1) analyze the value of the Keystone Visual Survey sub-tests in discriminating between mentally deficient children and normal children with reading difficulties; (2) investigate the effect of intelligence in determining responses to the Keystone Visual Survey Tests; and (3) test the validity of the use of the Keystone Visual Survey Tests for vision screening of the mentally retarded.

This exploratory study investigated the relationships between community college students' Myers-Briggs typology preferences and their problem-solving skills. The literature provides reason to believe that students' MBTI preferences are related to problem-solving style and ability. The educator's ability to teach problem-solving will be enhanced through an identification of motivational patterns affecting learning. A sample of 577 community college students participated in the study. Achievement Level for each student was identified using the New Jersey College Basic Skills Placement Test. In addition, problem-solving ability was measured using the New Jersey Test of Reasoning Skills. The Myers-Briggs Type Indicator, Form F, provided the MBTI profile scores. Chi Square analyses, correlations, and stepwise regression techniques were employed to identify and test relationships. The best identified predictor was the student's preference on the Sensing/Intuition index. Preference on the Judgment/Perception index also proved to be significant. Students who have the least skills in mathematics problem-solving have stronger preferences in the direction of the sensing dimension and the judgment dimension. Implications and recommendations for classroom instruction were presented and recommendations for related research were suggested. / Ed. D.
