An evaluation of the construct validity of situational judgment tests

Trippe, David Matthew 10 December 2002 (has links)
Situational judgment tests are analogous to earlier forms of "high fidelity" simulations such that an ostensible paradox emerges in the consistent finding of criterion-referenced validity but almost complete lack of construct validity evidence. The present study evaluates the extent to which SJT's can demonstrate convergent and discriminant validity by analyzing a SJT from a multitrait-multimethod perspective. A series of hierarchically nested confirmatory factor models were tested. Results indicate that the SJT demonstrates convergent and discriminant validity but also contains non-trivial amounts of construct-irrelevant method variance. Wide variability in the content and validation methods of SJT's are discussed as the reason previous attempts to find construct validity have failed. / Master of Science

Train drivers' experiences of witnessing a railway suicide : a repertory grid study

Connabeer, Rebecca Ann January 2013 (has links)
Over 200 railway suicides occur on the British Rail Network (BRN) every year. Research into the physical and psychological effects of this traumatic event on train drivers has been limited, and has focused very little on the mediating influence of personal factors. Kelly’s Personal Construct Psychology (PCP, 1955) was used in the current study to explore the relationship between train drivers’ views of themselves and others, and the psychological impact of witnessing a railway suicide. This was achieved through the use of repertory grid technique. Repertory grid measures of tightness of the overall construct system, level of elaboration of the self and others, construed distances between the self and others, conflict, extremity of ratings, and superordinacy were compared with participants’ scores on a measure of the psychological impact of the event (Impact of Event Scale Revised, IES-R, Weiss & Marmar, 1997). The fifteen participants in the study also completed a background information questionnaire. A content analysis of the constructs used in the repertory grids, and a thematic analysis of a follow up interview with two of the participants was also conducted. The findings indicated that most drivers experienced symptoms suggestive of a significant posttraumatic stress (PTS) reaction following the incident. For many this appeared to be short-lived, but for some the incident had longer lasting effects, and a third of the sample had been given an official diagnosis of Post-Traumatic Stress Disorder (PTSD). Possibly due to the small sample size, many of the correlations did not achieve statistical significance. However, discrepancy between the self and ideal self, and the number of moral constructs employed by participants, were both positively associated with reported levels of psychological distress. The superordinacy of the traumatised construct, and the number of emotional constructs employed by participants, were both negatively associated with reported levels of psychological distress. These findings therefore gave some support to Sewell and Cromwell’s (1990) PCP model of trauma, and to the importance of emotional processing of traumatic events. The thematic analyses added information about the nature of the changes experienced by train drivers following these events, and the impact of contextual factors. The repertory grid technique proved useful in measuring the influence of personal meaning making on the impact of traumatic events. The findings suggest that drivers can best be supported clinically by reducing the discrepancy between their self after the event and their ideal self, increasing their ability to emotionally process their experience, and by giving consideration to issues such as anger and blame. Limitations of the research are presented, as well as suggestions for further research.

Object Relations Theory and Personal Construct Theory: Rapprochement Opportunity

Rasile, Karen D. 08 1900 (has links)
Empirical investigation of the tenets of Object Relations Theory is recent. This study of the theoretical convergence between Object Relations Theory and Personal Construct Theory brought a new direction to the empirical investigation. It was hypothesized that individuals who displayed a well developed level of object relations, as measured by Object Relations Theory, would also display a highly adaptive blend of cognitive complexity and ordination, as described by Personal Construct Theory, and vice versa. A correlational analysis of personality measures on 136 college students approached but did not attain statistical significance. Results indicated no significant theoretical convergence between Object Relations Theory and Personal Construct Theory. Further research is warranted only if greater variability in sample age, life experience, and psychopathology is assured.

Personal constructs on resilience in swimming

Chambers, Timothy January 2008 (has links)
[Truncated abstract] Resilience is a concept that originated from behavioural science; a branch of research aimed at explaining unexpected benign or malignant outcomes associated with human development. It is a psychological construct that encompasses both cognitive and behavioural responses to negative situations and appears to exist at both an individual and group level. As a concept, resilience receives considerable attention from researchers within developmental psychology fields, who primarily identify numerous risk and protective factors. Within sport, however, researchers have demonstrated a preference for the examination of more traditional concepts, such as coping strategies. Moreover, few investigations in either domain employ a cogent theoretical framework to guide the research. Therefore, the present research program utilises Personal Construct Psychology (PCP; Kelly, 1955) principles to direct the proposed research. PCP is a theory about theories that emphasised our underlying ambition to make sense of the world, the events people encounter and themselves. According to Kelly, PCP is guided by the fundamental postulate and 11 corollaries. The PCP research template employed by the current research program promotes the utilisation of multimethod designs (i.e., qualitative and quantitative investigations) in order to understand and facilitate the development of resilience in swimming. Three research investigations are proposed to examine resilience in swimming, and are structured according to PCP. Each investigation is outlined below. Study 1. An interview protocol based upon key elements of Kelly s (1955) psychotherapy retrospective interview protocol was employed to elicit an understanding of resilience in swimming. Fourteen interviews were scheduled with elite Australian swimmers and swimming coaches, utilising the interview schedule. ... Study 3. The aim of this study was to design, implement and evaluate a resilience intervention for youth swimmers. Utilising the data generated from the first study, a resilience enhancement program was designed and delivered to 16 developmental swimmers over a period of three months. Resilience was measured pre, during and post intervention, and three months after the intervention. Resilience was also measured on an age and ability matched control group (n = 20), at the same time points. Results revealed improvements in resilience for the experimental group following the completion of the resilience program. In summary, the present research program employed a PCP (Kelly, 1955) research template to guide the aforementioned studies of resilience. The data collected from the research investigations contributed considerable knowledge to the resilience concept, and the sport psychology field. The qualitative study was the first of its kind to examine the concept in swimming, revealing several elements and process pertaining to resilience that later formed the foundations for the resilience intervention. General conclusions propose that future research combine psychological measurement of resilience and more traditional sport psychology concepts, in addition to the development of a sport specific psychometric measure of resilience.

An Ecocritical Exploration of McCandless’ Pilgrimage Into the Wild : A Literary Analysis of the Representations of Nature in Into the Wild

Taylor, Vicky January 2022 (has links)
This essay examines Jon Krakauer’s novel Into the Wild from an ecocritical perspective. It aims to analyse three representations of nature: its interdependence with culture, its connection with transcendence, and nature as a linguistic or cultural construct in Into the Wild and relate them to ecocriticism today. The analysis uses Peter Barry’s introduction to ecocriticism in Beginning Theory: An introduction to literary and cultural theory as its main theoretical framework, along with theories by famous ecocritics such as Laurence Coupe, Kenneth Burke, and William Rueckert. Christopher McCandless’ journey in Into the Wild highlights how it may no longer be possible to consider nature and culture as two separate entities due to the domestication of nature and humans alike. This analysis further discusses the potential reasons why individuals such as McCandless may feel a need to turn to nature as a solution for the problems they may experience in their lives. This exploration also considers how the attitude towards nature and wilderness has shifted and been reconstructed through time and how this may have helped shape McCandless’ mental image of nature and wilderness, which Krakauer explores in his novel.

Psychometric evaluation of a leadership empowerment questionnaire in selected organisations in South Africa / Desiree Zikalala

Zikalala, 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

Personal constructs and adjustment in secondary hypothyroidism

MacLean, Sarah Gemma January 2011 (has links)
Secondary hypothyroidism is caused by treatment for hyperthyroidism and is a chronic condition. After adequate treatment, people can continue to experience persistent physical and depressive symptoms. There is a lack of research into the psychological factors involved in the condition, such as how people adjust to hypothyroidism. The study used Kelly’s (1955) Personal Construct Theory to explore the way in which patients construe (appraise) themselves with hypothyroidism and how this relates to coping, depression and hypothyroid symptoms. Twenty participants were recruited from an endocrinology clinic and online, through thyroid support organisations. Participants completed a semi-structured interview called a repertory grid and self-report measures of coping (Brief COPE), depression (HADS) and hypothyroid symptoms (ThySRQ). Repertory grid measures were extracted such as distances between different views of the self. The results showed that how unfavourably the self now was viewed compared to self before a thyroid disorder was positively correlated with depression, dysfunctional coping and hypothyroid symptoms. Identification with a negative view of hypothyroidism was associated with poorer mental and physical health and with dysfunctional coping. Polarized (i.e. black-and-white) construing and tight (i.e. rigid) construing were significantly and positively related to depression scores. Tightness of construing was also related to the number of hypothyroid symptoms experienced. Dysfunctional coping was positively correlated with depression and hypothyroid symptoms. Those with a history of depression experienced significantly more hypothyroid symptoms. Exploratory multiple regression analyses uncovered that how unfavourably the person viewed themselves now compared with before any thyroid problem, hypothyroid symptom frequency and dysfunctional coping accounted for 82.9% of the variance in depression. This highlights the importance of understanding how people construe the experience of hypothyroidism and their coping strategies and therefore psychological interventions may be helpful. Limitations include a small sample size and a correlational design, whereby cause and effect conclusions cannot be drawn.
