The effects of prediction,understanding, and control: A test of the stress antidote model

Abstract

A study was undertaken to examine further the effects of perceived work control on employee adjustment. On the basis of the stress antidote model, it was proposed that high levels of prediction, understanding, and control of work-related events would have direct, indirect, and interactive effects on levels of employee adjustment. These hypotheses were tested in a short-term longitudinal study of 137 employees of a large retail organization. The stress antidote measures appeared to be indirectly related to employee adjustment, via their effects on perceptions of work stress. There was weak evidence for the proposal that prediction, understanding, and control would buffer the negative effects of work stress. Additional analyses indicated that the observed effects of prediction, understanding, and control were independent of employees' generalized control beliefs. However, there was no support for the proposal that the effects of the stress antidote measures would be dependent on employees' generalized control beliefs.     

Assessment of Identity and Quality of Life in Diabetic and Renal Transplant Adolescents in Comparison to Healthy Adolescents

Identity development represents a central task of adolescence. Identity achievement is characterized by a coherent sense of who one is following a period of exploration and can help navigate the challenges of adulthood. This study examined identity within a quality of life (QOL) context in 85 adolescents with a renal transplant or with Type 1 diabetes in comparison to 90 healthy controls. Results revealed significant differences in ideological identity, with patients showing higher levels of diffusion and controls showing higher levels of foreclosure. No differences with respect to interpersonal identity, QOL, perceived control over the QOL domains, and perceived opportunities for growth and development were found. Future research should assess identity and QOL over a longer period of time to determine whether differences between chronically ill and healthy young adults can be detected.     

Acceptability of Psychotherapy, Pharmacotherapy, and Self-Directed Therapies in Australians Living with Chronic Hepatitis C

Despite the prevalence of psychiatric co-morbidity in chronic hepatitis C (CHC), treatment is under-researched. Patient preferences are likely to affect treatment uptake, adherence, and success. Thus, the acceptability of psychological supports was explored. A postal survey of Australian CHC outpatients of the Royal Adelaide Hospital and online survey of Australians living with CHC was conducted, assessing demographic and disease-related variables, psychosocial characteristics, past experience with psychological support, and psychological support acceptability. The final sample of 156 patients (58 % male) had significantly worse depression, anxiety, stress, and social support than norms. The most acceptable support type was individual psychotherapy (83 %), followed by bibliotherapy (61 %), pharmacotherapy (56 %), online therapy (45 %), and group psychotherapy (37 %). The most prominent predictor of support acceptability was satisfaction with past use. While individual psychotherapy acceptability was encouragingly high, potentially less costly modalities including group psychotherapy or online therapy may be hampered by low acceptability, the reasons for which need to be further explored.     

The real meaning of constructivism

Personal construct theory has a focus on constructs rather than elements, as can be clearly seen in the corollaries proposed by George Kelly. Yet, in the operationalization of his fundamental postulate, namely the repertory grid technique, there is an equal focus on both constructs and elements. Here we examine the relative contributions to variation in the grid data of both elements and constructs and use the intraclass correlation to examine this in several data sets. It is shown that in many instances, elements contribute more to the variation in grid data, irrespective of whether elements and constructs are supplied or elicited, or whether the ratings are made construct by construct or element by element. Implications of this for both the theory and practice are discussed.     

ON TESTING THE COMMONALITY OF CONSTRUCTS IN SUPPLIED GRIDS

The repertory grid technique has long been the empirical tool of choice for research based on personal construct theory (Kelly, 1955). In some situations, respondents are asked to evaluate a set of elements with respect to a fixed or supplied repertoire of constructs, and an assumption is made that respondents will employ these constructs similarly. This situation is thus equivalent to the semantic differential technique. In the repertory grid context it is justified through the commonality of construing corollary of personal construct theory. This is an assumption that can be tested, although it seems to have attracted little attention in the past. Here a criterion for commonality of a construct is proposed, namely that of the data conforming to a unidimensional scaling model, and a simple method of testing this is illustrated.     

Rhythm and Semiotic Structures of Long-Term Ambivalence in the Dialogical Self: Eating Disorder and Recovery Voices

Ambivalence in the dialogical self is conceptualized as resistance to change. The cyclic processes that characterize ambivalence are seen to maintain a balance between opposing voices, producing dynamic stability in the self-system. What has not been incorporated in the study of ambivalence so far is consideration of structural levels from which the opposing voices are speaking. This prompted the present case study of long-term eating disorder ambivalence, which joins a consideration of semiotic system structure with process. In interviews with a young woman conducted over a three-year period, cyclic processes of eating disorder and recovery voices were pervasive, yet structural analysis of the subsystems and their transactions suggested that change was actually occurring in this presumably change-resistant system, pointing to a need for reconceptualizing ambivalent systems in relation to development.     

Theory-Appropriate Analysis of Repertory Grid Data

Abstract

This paper reviews the relationship between personal construct theory and methods of repertory grid analysis. Traditional methods, such as factor or cluster analysis, are shown to relate to the fundamental postulate or construction corollary, while new hierarchical approaches relate to the structural corollaries of organization and range.     

Visual distraction increases the detection of an unexpected object in inattentional blindness

Distraction is typically thought to be detrimental to performance and concentration, and stimuli are classified as “distractions” if they take attention away from a primary task. However it has been shown that, under certain circumstances, distractors can also improve task performance. The current study extends this literature by exploring the role of a single discrete transient visual distracting event in increasing attention to an unexpected visual object in an inattentional blindness (IB) paradigm. Experiment 1 investigated the impact of a 48 ms visual distraction stimulus on rates of IB; a second experiment used a shortened, 16 ms visual distracting event. Both the long 48 ms and brief 16 ms distractors significantly reduced overall IB rates, by approximately 50% compared to a no distractor condition. Moreover, this reduction in IB is obtained independent of whether the visual distracting event was noted by the observer. Our findings demonstrate that a single discrete visual distraction can improve the detectability of an unexpected object in an IB task. Implications for theories of distributed attention in such tasks are discussed.     

Hostility explains some of the discrepancy between daytime ambulatory and clinic blood pressures.

The authors examined whether hostility explained the discrepancy commonly observed between clinic and daytime ambulatory blood pressures. Daytime ambulatory blood pressure (DABP) was assessed every 45 min over 6 days in healthy adults (N = 120). After controlling for demographic variables, time-varying covariates such as position and activity level, and clinic blood pressure (CBP), the Cook-Medley Hostility Scale was significantly associated with daytime ambulatory diastolic blood pressure. No support was obtained for mediation by psychological factors. Discrepancies between DABP and CBP may be due, in part, to differences in the degree to which these 2 types of measures are associated with individual differences in hostility. These results suggest that the addition of hostility to CBP may improve its predictive power.
