A range of electronic databases and two journals were subjected to a detailed literature search, focusing on studies evaluating psychological interventions with children aged 0-5 years of age. Outcome studies, utilising experimental design, were included for critical review. The search strategy revealed predominantly attachment-informed intervention studies, prompting a review of this aspect of the literature. A total of twelve studies were identified for closer scrutiny: five with a preventative focus; four describing interventions with clinical populations and three detailing large-scale intervention programmes. This review found evidence that early interventions are effective in altering maternal sensitivity and insecure patterns of attachment. Moreover, interventions were effective in reducing the effects of postnatal depression on attachment security, reducing the incidence of placement breakdown in fostered and adopted children and preventing behaviour difficulties in school-age children. These findings indicate a burgeoning evidence base for attachment-based intervention models for the prevention or treatment of infant or child psychopathology.

Researchers have demonstrated clear benefits to humans in their relationships with companion animals; however, little is known about how these animals may benefit from their relationships with humans. The purpose of the current study is to investigate potential benefits to a pet of living in a household, as defined by an array of specific pet owner behaviors. A second purpose is to investigate the relationship between self-reported attachment to a pet and dimensions of potentially beneficial owner behaviors on behalf of that animal. Participants in the current study were pet-owning undergraduate students (N = 501) from a large Midwestern university who were surveyed on an array of behaviors they may perform for or with a companion animal. Self-reported attachment to the animal was measured using the Lexington Attachment to Pets Scale (Johnson, Garrity, & Stallones, 1992). Factor analysis resulted in five dimensions of behavior for dog owners (n = 350), named Indoor/Outdoor, Attention, Inclusion, Well-being, and Safety. Four dimensions were found for cat owners (n = 151) and named Indoor/Outdoor, Indulgence, Possessions, and Independence. The Indoor/Outdoor dimension was similar to factors found in previous research. The rest of the dimensions appear to be uniquely important in terms of either dog or cat ownership. Regression analysis using factor scores to predict attachment revealed that 38.6% of the variance in attachment scores for dog owners and 23.6% for cat owners was explained by the dimensions. The results of the factor analysis provide a picture of what human care giving might mean, in terms of beneficial behavior, to the animal. The results also indicate that the basic needs of companion animals are being met regardless of the degree of attachment: low attachment may not necessarily mean poor care. Attachment does, however, appear to make a difference in the life of a companion animal in terms of enrichment. Dog owners who report higher attachment tend to include the dog in family activities, and provide certain kinds of attentions. Cat owners who report higher attachment are more likely to have a cat that stays close by their side, and are also more likely to provide gifts and treats to the cat. / Thesis (Ph.D.)--Wichita State University, College of Liberal Arts and Sciences, Dept. of Psychology. / "May 2005."

This thesis examines the effectiveness of acupuncture therapy in the treatment of psychological and somatic distress in the context of medically unexplained symptoms (MUS). Also, it explores the role of psychological attachment and experiential avoidance in an effort to explain potential mechanisms of acupuncture’s effect. Existing literature demonstrates some level of effectiveness of acupuncture therapy for the treatment of depression, anxiety and somatic symptoms. However, a lack of experimental rigor in methodology means that existing results cannot be shown to be superior to a placebo and thus current treatment protocols for patients with MUS do not include a recommendation of acupuncture therapy. MUS are defined as any set of symptoms that cannot be explained by organic disease, these clusters of symptoms are theorised to be of psychological aetiology. Sufferers of MUS find themselves stuck in a perpetual loop of secondary care referrals with little or no treatment options being made available. Whilst there is some evidence that talking therapies, such as cognitive behavioural therapy, are effective, their availability, efficacy and stigma mean they are often not desired by patients who suffer with MUS. Previous research has shown that insecure attachment predicts higher instances of, psychological and somatic distress, as well as MUS. Previous work undertaken by the author of this thesis also suggests that there may be a moderating effect of attachment in acupuncture therapy outcomes. In order to investigate acupuncture’s efficacy a double-blind randomised control trial was undertaken; 63 participants were randomised to receive either five treatments of genuine acupuncture or a non-penetrating sham form of acupuncture using the Park sham acupuncture device. A rigorous procedure ensured participant and practitioner blinding to group allocation. Primary measures of psychological (GHQ) and somatic (BSI) distress were taken at pre, post and follow-up time points (8 weeks). Secondary measures included general attachment (RQ), experiential avoidance (MEAQ) and client attachment to therapist (CATS). Results showed a significant effect of acupuncture over placebo in the reduction of both psychological (GHQ) and somatic distress (BSI). This therapeutic effect was maintained at 8-week follow-up. Further results showed moderation effects of secure attachment on somatic symptoms in the treatment group but not placebo group. Experiential avoidance also moderated somatic symptom outcomes in the treatment but not placebo group. A subsequent study utilising a quasi-experimental multi-centre methodology, which used identical measures to the previous experiment, revealed the same significant reduction of both psychological and somatic distress. This study consisted of 184 participants across five clinics, each participant receiving five sessions of acupuncture. Similar results were observed regarding moderation effects of secure attachment on treatment outcomes of somatic symptoms. Results also showed differences in moderation effects between participant with a MUS diagnosis vs. those without. Findings of both studies suggest acupuncture is an effective treatment for psychological and somatic distress, as well as MUS. The differences in attachment moderation effects between treatment and placebo may indicate acupuncture’s ability to elicit endogenous opioid release in the brain. However, further neurological studies are required to confirm this hypothesis.

Technology has been an integral part of human life since the 19th century’s Industrial Revolution, and the advancement of technologies has continued into the 21st century. Of all new emerging technologies, the computer has been identified as the most important, most complex and fastest emerging technology. In order for businesses to compete and survive within the business world, they are compelled to adopt new computer technologies. However, computers alone cannot improve organisational performance. Computers need to be accepted, optimally used and utilised by employees in order for an organisation to succeed. One such technology is SAP AG’s Enterprise Resource Planning (ERP) system which is a real-time, fully integrated business system used by more than 170 000 organisations in 120 countries. Measuring information system success has been a concern since its inception due to its complexity and difficulty to appraise. Researchers traditionally attempted to measure success by the delivering of a functional information system product within certain monetary and time constraints. Subsequently, evidence suggested that a more accurate measure of success lies within the field of system use. One model of assessing and predicting user acceptance and which has gained popularity in recent years is the Technology Acceptance Model (TAM). Apart from accepting the SAP ERP system, users should also be of the intention to continuously use it as a job requirement. The model for measuring user commitment is psychological attachment which determines whether the commitment is insincere and temporary, or long-lasting. Further, not only do users need to accept and continuously use an information technology like SAP ERP; they also need to be able to cope while using it. If not, psychological stress known as techno stress develops and prevents the optimal use of this system. With these three possible explanations for computer technology avoidance as a premise of departure, this study aims to determine the congruence, if any, between the sub-constructs of the TAM (perceived ease of use, perceived usefulness, attitude toward using, behavioural intention to use and actual system use), psychological attachment (compliance, identification and internalisation), and techno stress (negative computer thoughts) within a South African SAP ERP user environment. A cross-sectional survey design was used rendering a convenience sample of N = 241 from among the SAP ERP user fraternity at a South African steel manufacturer. The measuring instruments used were the 23-item Technology Acceptance Questionnaire (TAM), the 10-item Psychological Attachment Questionnaire (PAQ) and the 20-item Computer Thoughts Survey (CTS-C). Study 1 which was a literature review confirmed conceptual congruence in that although the technology acceptance model was the most parsimonious, powerful and widely applied theoretical model, it was constrained due to the omission of social influence (psychological attachment) as a contributing factor in the processes of behavioural change towards technology acceptance. Furthermore, it was found that techno stress lowers employee efficiency and creates dissonance in the work environment, resulting in acceptance, hesitance or resistance towards the technology in question. Congruence was established between the system itself (technology acceptance), social relationships (psychological acceptance), and inherent psychological stress (techno stress). The aim of study 2 was to test the technology acceptance model within a South African SAP ERP user environment. Structural equation modelling confirmed that positive inter-construct relationships exist between all TAM constructs. Actual system use, which is the measurement for technology acceptance, was directly affected by behavioural intention to use and indirectly by perceived usefulness. In turn, behavioural intention to use was directly affected by perceived usefulness, attitude toward using and indirectly by perceived ease of use. Attitude toward using was directly affected by perceived ease of use and perceived usefulness. Perceived usefulness was directly affected by perceived ease of use. Study 3 revealed that internalisation had a direct positive effect on behavioural intention to use and an indirect effect on actual system use via behavioural intention to use. Furthermore, in this study identification had direct positive effects on internalisation, perceived usefulness, perceived ease of use and actual system use. Indirect effects emerged between identification and behavioural intention to use via internalisation as well as behavioural intention to use via perceived usefulness. Compliance, on the other hand, had negligible, negative direct effects on all TAM constructs of which the most prominent was that on attitude toward using. Results acquired from structural equation modelling in study four confirmed that weak negative relationships existed between techno stress and all TAM constructs. This finding is contrary to other studies and can be attributed to the fact that participants in this study were at large, proficient around SAP ERP and therefore experienced low levels of techno stress. Furthermore, aspects such as effective training, clear deadlines, effective teamwork, recurrent performance evaluations, job security, career development and realistic job load are all antidotes for techno stress which is believed to be current within the participant fraternity. In a concluding chapter the conclusions derived from the literature review, as well as the empirical research were presented and recommendations flowing from this research study were made. / PhD (Psychology), North-West University, Vaal Triangle Campus, 2014

People effectiveness has become a key differentiator of competitive advantage in the knowledge economy and the need for a valid and reliable measure of people effectiveneness has become paramount for success. The research positions the psychological work immersion scale (PWIS) as a relevant measure of people effectiveness and explores the relationship between the PWIS variables (psychological attachment and people effectiveness enablers) and perceptions of business performance. Furthermore the research explores whether higher levels of psychological work immersion leads to increased business performance over time in an attempt to position the value of organisational development interventions aimed at increasing psychological work immersion levels in the work place. The setting for this research was a not-for-profit organisation in South Africa. The sample for the study was measured at two defined points in time over a 14-month period and consisted of n = 414 (T1) and n = 551 (T2). The study showed that the PWIS factor structure is a valid measure of the psychological work immersion construct across time (T1 and T2). The results provided evidence of convergent, intra-discriminant and external discriminant validity (construct validity) of the PWIS within (T1 and T2) and over time (T1 vs T2). The results showed that the PWIS has acceptable internal consistency reliability within and across time (T1 and T2) as well as demonstrating test-retest reliability across time. The results provided evidence that the people effectiveness enablers and psychological attachment variables significantly predict perception of business performance indicators (profit/loss, costs, and cash flow related to operating activities), and that strong perceptions of people effectiveness enablers relate to strong individual perceptions of business performance through a high sense of psychological attachment. The mediation results confirmed the test-retest reliability and validity of the PWIS in predicting perceptions of business performance within and over time. This finding shows that psychological attachment is an important factor in terms of iv influencing the individual perceptions of business performance which is related to improvements in actual business performance. The study also showed evidence of a positive relationship between psychological work immersion and business performance and demonstrated improvements in psychological work immersion coincided with year on year improvements in business performance. The study contributes towards the current literature on organisational development and specifically on the measurement of people effectiveness within knowledge economy organisations. / Industrial and Organisational Psychology / D.

This research focused on constructing a psychological profile for change interventions by investigating both the interrelationships and overall relationships between work stress (as the independent variable), psychological attachment (job embeddedness and organisational commitment) (as the mediating variables) and attitudes towards change (as the dependent variable). A non-experimental cross-sectional quantitative survey design approach using standardised valid and reliable measuring instruments (Sources of Job Stress Scale, Organisational Commitment Questionnaire, Job Embededdness Questionnaire, Attitudes towards Change Questionnaire) was used on a non-probability purposive sample of employees from one of the largest, fast-moving consumer goods companies in South Africa (N = 350), ranging from administrative to executive level. Bivariate correlations showed a statistically positive inter-relationship between sources of work stress, psychological attachment (job embeddedness and organisational commitment) and attitudes towards change. A canonical correlation analysis indicated a significant overall relationship between the sources of work stress, psychological attachment (job embeddedness and organisational commitment) and attitudes towards change dispositions. Mediation modelling revealed the mediating role of psychological attachment (organisational commitment and job embeddedness) in the sources of work stress and attitudes towards change relationship. Moderated hierarchical regression analyses showed that age and gender significantly moderated the relationship between individuals’ sources of work stress and their attitudes towards change dispositions. Tests for mean differences revealed that significant differences exist between age and sources of work stress, affective and continuance commitment, fit and sacrifice embeddedness. Differences exist between race groups’ affective and continuance commitment. Job security is a concern across all employment levels in the organisation. Individuals at an executive, upper administrative and administrative level revealed significant differences in terms of their continuance commitment. Cognitive and behavioural attitudes towards change did not differ significantly across all employment levels. At a theoretical level, this study developed an understanding of the cognitive, affective, conative and interpersonal behavioural dimensions of the hypothesised psychological profile to manage change. At an empirical level, it developed an empirically tested psychological profile for change interventions in terms of the various behavioural dimensions. At a practical level, organisational change practices in terms of the behavioural dimensions of the psychological profile were recommended. / Psychology / D. Phil. (Psychology)
