Commitment to organizational change: extension of a three-component model

Three studies were conducted to test the application of a three-component model of workplace commitment (J. P. Meyer & N. J. Allen, 1991: J. P. Meyer & L. Herscovitch, 2001) in the context of employee commitment to organizational change. Study 1, conducted with 224 university students, provided preliminary evidence for the validity of newly developed Affective, Continuance, and Normative Commitment to Change Scales. Studies 2 and 3, conducted with hospital nurses (N = 157 and 108, respectively), provided further support for the validity of the three Commitment to Change Scales, and demonstrated that (a) commitment to a change is a better predictor of behavioral support for a change than is organizational commitment, (b) affective and normative commitment to a change are associated with higher levels of support than is continuance commitment, and (c) the components of commitment combine to predict behavior.     

Sentential constants in R and R⌝

In this paper, we shall confine ourselves to the study of sentential constants in the system R of relevant implication.In dealing with the behaviour of the sentential constants in R, we shall think of R itself as presented in three stages, depending on the level of truth-functional involvement.     

A Cross-Lagged Panel Approach to Understanding Social Support and Chronic Posttraumatic Stress Disorder Symptoms in Veterans: Assessment Modality Matters

Although there is a strong and consistent association between social support and posttraumatic stress disorder (PTSD), the directionality of this association has been debated, with some research indicating that social support protects against PTSD symptoms, whereas other research suggests that PTSD symptoms erode social support. The majority of studies in the literature have been cross-sectional, rendering directionality impossible to determine. Cross-lagged panel models overcome many previous limitations; however, findings from the few studies employing these designs have been mixed, possibly due to methodological differences including self-report versus clinician-administered assessment. The current study used a cross-lagged panel structural equation model to explore the relationship between social support and chronic PTSD symptoms over a 1-year period in a sample of 264 Iraq and Afghanistan veterans assessed several years after trauma exposure. Approximately a third of the sample met criteria for PTSD at the baseline assessment, with veterans’ trauma occurring an average of 6 years prior to baseline. Two separate models were run, with one using PTSD symptoms assessed via self-report and the other using clinician-assessed PTSD symptoms. Excellent model fit was found for both models. Results indicated that the relationship between social support and PTSD symptoms was affected by assessment modality. Whereas the self-report model indicated a bidirectional relationship between social support and PTSD symptoms over time, the clinician-assessed model indicated only that baseline PTSD symptoms predicted social support 1 year later. Results highlight that assessment modality is one factor that likely impacts disparate findings across previous studies. Theoretical and clinical implications of these findings are discussed, with suggestions for the growing body of literature utilizing these designs to dismantle this complex association.     

The Impact of Films on Viewer Attitudes towards People with Schizophrenia

The media, including television, newspapers, and popular films have been implicated in the facilitation of mental illness stigmatization by presenting negative and inaccurate depictions of various diagnoses. The current study examined the impact of film on participants’ knowledge, attitudes, and behaviors towards people with schizophrenia. A total of 106 participants completed questionnaires before and after viewing a 45-min film excerpt. Films viewed included a fear-based inaccurate, likeable-inaccurate, and an educational-accurate depiction of schizophrenia. There was also a control group. There were significant increases in stigmatizing attitudes for participants in the fear-based inaccurate group compared to the accurate and control group. Fear-based participants reported increased negative affect and endorsed statements suggesting that people with schizophrenia were unpredictable, dependent, and dangerous. These results provide support for the hypothesis that negative, inaccurate portrayals of severe mental illness enhance stigmatizing attitudes. Accurate film depictions, advocacy for social equality, and the continued education of individuals, clients, families, communities and organizations will help to mitigate the impact of films on mental illness stigmatization.
