Concurrent and Incremental Validity of Parent- and Teacher-Report and Neuropsychological Measures of Executive Functions, Attention, and Hyperactivity in an Outpatient Community Mental Health Clinic Pediatric SampleFruehauf, Lindsay Morgan 16 June 2022 (has links) (PDF)
Attention-deficit/hyperactivity disorder (ADHD) is a common neurodevelopmental disorder that affects academic, social, and health functioning. The psychometric properties of measures commonly used in diagnostic settings to assess the constructs of attention, hyperactivity, and executive functioning, including concurrent and incremental validity with other commonly used measures, are not well-established. Additionally, these specific psychometric properties within ecological samples of children and adolescents presenting to community-based clinics is infrequent. The purpose of this dissertation was to describe a sample of children and adolescents presenting to a community-based mental health clinic and to test the concurrent and incremental validity of parent- and teacher-report questionnaires and neuropsychological measures of inattention, hyperactivity, and executive functioning. Participants included a consecutive sample of 597 youth aged six to eighteen years presenting to a community-based mental health clinic for a psychological assessment between 2010 and 2019. Measures included the BASC (2nd and 3rd editions), Conners 3 (long and short forms), BRIEF (1st and 2nd editions), D-KEFS, NEPSY-II, and CPT (2nd and 3rd editions). Approximately 50% of individuals were diagnosed with ADHD. Correlations between attention, hyperactivity, and executive function constructs on questionnaires were significantly and moderately-to-strongly correlated (Spearman’s = .27-.82) to each other (e.g., BASC Hyperactivity and Conners Hyperactivity/Impulsivity subscales) and across parent and teacher forms (e.g., Conners Parent Inattention and Conners Teacher Inattention subscales). Constructs measured by neuropsychological tests were not significantly correlated to similar constructs measured by other neuropsychological measures or questionnaires (e.g., inhibition measured by NEPSY-II Response Set and BRIEF Inhibition subscale; Spearman’s = .02-.38). Logistic regression analyses suggested that measures such as the BASC, BRIEF, NEPSY-II, and CPT do not clinically significantly increase prediction of ADHD diagnosis above and beyond the Conners 3. Results indicate convergence of information with potential redundancy in the assessment and diagnosis of ADHD across questionnaire measures and informants. Questionnaires and neuropsychological measures were not correlated, suggesting they measure different constructs or different aspects of the same construct. Results indicate that clinicians may sufficiently rely on questionnaires and reduce the number of other neuropsychological measures administered during a diagnostic assessment without significantly reducing diagnostic accuracy. However, the value of evidence of symptoms in multiple settings and converging information should still be considered.

The DR Congo English state examination: some fundamental validity issuesKatalayi, Godefroid Bantumbandi January 2012 (has links)
<p>The test context is of paramount importance in language testing as it provides an understanding of the kind of tasks to be included in the test, how these tasks are executed by the test takers and how they can be efficiently administered. The objective of this study was to investigate the extent to which the context of the DR Congo English state examination (ESE) is valid and to come out with some useful suggestions that are likely to improve its validity. Two basic theories, the modern validity theory and the schema theory, informed this study. Weirâs (2005) socio-cognitive framework was used to build the validity argument for the evaluation of the English state examination.</p>
<p>A mixed method was used where the research design consisted of the combination of both qualitative and quantitative data during the collection and analysis stages. The content document analysis method was used to examine the content of the different state examination papers so as to identify the main features of the test, and the statistic (descriptive) method was used to quantify observations identified in the state examination papers and to evaluate the context validity of the ESE. Three techniques were used to collect the research data: the questionnaire, the<br />
test, and the interview.</p>
<p>Three main findings of this study were reported: (1) the conditions under which the ESE tasks are performed and the relevance of these tasks to the test domain and characteristics are still far to contribute to the quality of evaluation of high school finalist students / (2) the extent to which the ESE includes tasks that take into consideration the nature of information in the text as well as the knowledge required for completing the task is globally good / (3) the conditions under which the test takes place are poor and these conditions affect the validity of test scores. The study recommends the test developers to approximate test tasks to those students have been exposed to in classroom situations and those they are likely to encounter in real life. It also recommends all the people involved in the administration of the test to adhere to high ethical standards.</p>

Moral distress in South African professional nurses : instrument development / Richelle van WaltslevenVan Waltsleven, Richelle January 2014 (has links)
Nurses experience stress, fear and anger while they are trying to reconcile their ideals/ goals about health care with its inadequacies and abuses (Jameton, 1984:5), while at the same time trying to stay true to their convictions (Lindh et al., 2010:552). Moral distress is experienced when nurses cannot adhere to these goals (Corley, 2002:637). Conflicting moral principles, stress-provoking and contradicting demands weaken the nurse’s sense of control, power and autonomy (Lützen et al., 2010:213). The current descriptions of moral distress inadequately define the concept, and this might lead to the inconsistent use of the term moral distress. Therefore, conceptual clarity is needed. Current available instruments measure antecedents and situations causing moral distress. Therefore, an instrument measuring the attributes of moral distress is urgently needed. Such an instrument might be used in a variety of clinical departments because it is not based on department-specific situations but on the attributes of moral distress. Moral distress has a great impact on the nurse, patient care and the organization.
This research used Benson and Clark’s (1982) method of instrument development as a theoretical framework. It is the aim of this study to develop and validate an instrument to measure moral distress in the clinical health care context of the professional nurse. In order to attain this aim the following objectives were set: To conduct an integrative literature review to identify antecedents, consequences, attributes and empirical indicators of moral distress; to conduct interviews to explore professional nurses’ experience of moral distress; to develop an instrument to measure moral distress in professional nurses; to validate the instrument. A qualitative and quantitative research design with explorative, descriptive and contextual strategies was used.
The research process was divided into phases. During Phase One, an integrative literature review was conducted and the population included all available national and international data on moral distress in nurses/ nursing and sampling included all-inclusive sampling. Data analysis was performed through descriptive synthesis.Phase Onealso included semi-structured interviews and the population included professional nurses working in hospitals and clinics in the North-West Province. The sampling method applied was purposive sampling. Tesch’s method was used as data analysis method. During Phase Two, a content validation was conducted and the population included experts in the field of moral distress and instrument validation, and purposive sampling was applied. Data collection was done through the instrument that was developedand data analysis was the content validity index. Phase Twoalso included a qualitative evaluation which was conducted and the population consisted of professional nurses working in hospitals and clinics in the North-West Province and purposive sampling was applied. Data was collected through the developed instrument and a focus group session. Data analysis was conducted through aconsensus discussion. During Phase Three, a pilot study was conducted and the population was professional nurses working ina hospital with different departments and clinics in the Free State Province. All-inclusive sampling was applied and the instrument that was developed was used as data collection. Data analysis included: Descriptive statistics, factor analysis (exploratory, confirmatory and Bartlett’s test of spherity), Cronbach’s alpha coefficient, correlations and ANOVA. According to the results from the face-, content-, exploratory and confirmatory, discriminant- as well as divergent validity, the instrument has been shown to be valid. The Cronbach’s alpha for the Moral Distress Instrument was deemed reliable. Finally, the research was evaluated and limitations were identified. Recommendations for nursing education, -practice, research and policy were formulated. / PhD (Nursing), North-West University, Potchefstroom Campus, 2014

Psychometric evaluation of a leadership empowerment questionnaire in selected organisations in South Africa / Desiree ZikalalaZikalala, Senzekile Nompumelelo Desiree January 2015 (has links)
The world of work has become extremely volatile, with the scarcity of skills and the management of human capital at the top of the agenda. Human capital is the most valuable asset in any organisation. It is evident that leadership is vital in organisations in ensuring their success; thus making leadership empowerment behaviour crucial. It is essential that our leaders become people developers who focus on growing and up skilling subordinates as a way of attracting and retaining talent. It is important that leaders create an enabling environment for their subordinates; one of independence, innovation and, more importantly, growth and development. The purpose of this study was to explore the psychometric properties of the leadership empowerment questionnaire by investigating internal consistency; furthermore investigating the differences between genders regarding male and female perceptions of leadership empowerment behaviour. A quantitative cross-sectional survey was used. The measuring battery comprised the Leadership Empowerment Behaviour Questionnaire (LEBQ), which is originally a six-factor structure. The analysis was carried out using the IBM-SPSS and Mplus statistical modelling programs. Reliability was explored by utilising the Confirmatory Factor Analysis (CFA) index (rho). Construct validity was assessed by examining the factor structure, utilising the Exploratory Factor Analysis (EFA) and the CFA. Satisfactory reliability indices were attained. A three-factor model of the LEBQ was confirmed. The three-factor model consists of autonomy, development and accountability. Measurement invariance was tested by the use of configural, scalar and metric invariance. The configural model concluded that the three-factor structure obtained for the total sample also holds for the two groups (Males & Females) of respondents separately. The metric model indicates that the latent variables are measured in the same way with the same metric in the two target groups. The Scalar model indicates that on these three items, males and females differ regarding their starting points in their response to these questions. Although there were differences in the starting points of certain items, there were no real differences evident in the overall model regarding males and females. Recommendations for further research were made. / MA (Industrial Psychology)--North-West University, Vaal Triangle Campus, 2015
