Negative affectivity,perceived occupational stress,and health during organisational restructuring: A follow-up study

Abstract

This paper presents a survey of the relationships among multiple indicators of perceived occupational stress, trait negative affectivity, and later mental and physical health symptoms, among 157 Australian public servants during organisational restructuring. It was hypothesised that individual differences in negative affectivity would inflate the relationships between perceived stress and later strain as assessed by health symptoms in the follow-up phase. The possible role of negative affectivity in moderating the stress-strain relationships was also investigated. Multiple regression analyses conducted with depressive and physical health outcomes separately indicate that the only significant predictors of depressive symptoms were negative affectivity and role insufficiency, whereas the significant predictors of physical health symptoms were role ambiguity, physical environment, and negative affectivity. None of the interaction terms involving occupational stress and negative affectivity was found to be significant Implications of the findings are discussed in the context of the research literature on work stress, particularly the role of negative affectivity in inflating the stress-strain relationship and indications for future research.     

Accuracy of respiratory symptom perception in persons with high and low negative affectivity

Accuracy of respiratory symptom perception was investigated in different contexts in participants (N = 56) scoring high or low for negative affectivity (NA). Within subject-correlations were calculated between minute ventilation (frequency per minute × tidal volume) and the subjective symptom ‘faster and/or deeper breathing’ across 10 subsequent breathing trials of 2?min with varying air mixtures, containing fresh or foul smelling odours and/or 5.5% CO₂. Half the participants were given a positive information frame for the sensations (‘some air mixtures may induce a pleasantly arousing feeling, like when being in love’), whereas the other half was given a negative frame (‘some air mixtures may induce feelings of being anxious and distressed’). Interoceptive accuracy was overall fairly high (r = 0.56–0.74), but it dropped considerably (r = 0.27), when bodily sensations were induced in high NA persons in a negative information frame (interaction, p < 0.005). Interoceptive accuracy appears low when persons with high NA are in situations characterised by negative affective cues.     

On the Hand Transport Component of Prehensile Movements

Jeannerod (1981) proposed that prehensile movements involve two independent visuomotor channels that are responsible for hand transport and hand aperture. In many studies, the movement of a marker placed on the wrist has been used as an index of hand transport because wrist movement is unaffected by the movements of the digits responsible for hand aperture. In the present study, the spatial paths of the wrist, index finger, and thumb of 5 adults, each performing 50 reaching movements, were measured with a WATSMART movement tracking system, and their variability was analyzed. The measures of movement variability suggest that the motor system is more concerned with thumb position than with wrist position during hand transport. Although the wrist is a technically convenient index of hand transport, the thumb may be a more appropriate index from the point of view of motor control.     

Cultural Inclusiveness Contributing to International Students' Intercultural Attitudes: Mediating Role of Intergroup Contact Variables

This study sought to examine the relationships among Asian‐born international students' perceived cultural inclusiveness and intercultural contact, along with the contributions these variables made to the students' attitudes towards culturally different domestic students. Based on Pettigrew's (1998) intergroup contact theory and previous research on educational cultural climate, we hypothesised that more positive intercultural attitudes would be associated with perceptions of a culturally inclusive educational environment and higher levels of intergroup contact as indicated by quantity of contact, quality of contact, and extent of intercultural friendships. Anonymous survey participants were 190 (76 male and 113 female) Asian‐born international university students at an Australian university. Results showed small to moderate relationships among perceived cultural inclusiveness, all the dimensions of intercultural contact, and intercultural attitudes, except for an unexpected insignificant association between intercultural friendship and attitudes. Hierarchical regression analysis showed that cultural inclusiveness and quality of contact were the only significant predictors of intercultural attitudes. Mediation analysis indicated that quality of contact partially mediated the relationship between cultural inclusiveness and intercultural attitudes. The importance of an inclusive educational environment on intergroup contact and attitudes, from international students' viewpoint, is discussed. Copyright © 2014 John Wiley & Sons, Ltd.     

L-type voltage-gated calcium channels in conditioned fear: a genetic and pharmacological analysis

Using pharmacological approaches, others have suggested that L-type voltage-gated calcium channels (L-VGCCs) mediate both consolidation and extinction of conditioned fear. In the absence of L-VGCC isoform-specific antagonists, we have begun to investigate the subtype-specific role of LVGCCs in consolidation and extinction of conditioned fear using a molecular genetics approach. Previously, we used this approach to demonstrate that the Ca(v)1.3 isoform mediates consolidation, but not extinction, of contextually conditioned fear. Here, we used mice in which the gene for the L-VGCC pore-forming subunit Ca(v)1.2 was conditionally deleted in forebrain excitatory neurons (Ca(v)1.2(cKO) mice) to address the role of Ca(v)1.2 in consolidation and extinction of conditioned fear. We demonstrate that Ca(v)1.2(cKO) mice consolidate and extinguish conditioned fear as well as control littermates. These data suggest that Ca(v)1.2 is not critical for these processes and together with our previous data argue against a role for either of the brain-expressed L-VGCCs (Ca(v)1.2 or Ca(v)1.3) in extinction of conditioned fear. Additionally, we present data demonstrating that the L-VGCC antagonist nifedipine, which has been used in previous conditioned fear extinction studies, impairs locomotion, and induces an aversive state. We further demonstrate that this aversive state can enter into associations with conditioned stimuli that are present at the time that it is experienced, suggesting that previous studies using nifedipine were likely confounded by drug toxicity. Taken together, our genetic and pharmacological data argue against a role for Ca(v)1.2 in consolidation of conditioned fear as well as a role for L-VGCCs in extinction of conditioned fear.     

Perfectionism,Distress, and Irrational Beliefs in High School Students: Analyses with an Abbreviated Survey of Personal Beliefs for Adolescents

The current study examined the associations between dimensions of perfectionism and irrational beliefs in an adolescent sample. In addition, we tested the association between psychological distress and irrational beliefs in adolescents and we evaluated the feasibility of creating a modified version of the Survey of Personal Beliefs for use with adolescents. A sample of 250 adolescents (108 males, 142 females) completed the Child-Adolescent Perfectionism Scale, the Survey of Personal Beliefs, and the CES-D Depression Scale. Initial psychometric analyses yielded an abbreviated 30-item Survey of Personal Beliefs with adequate internal consistency for four of the five subscales. Our results showed that self-oriented perfectionism was associated significantly with all five irrational belief subscales, while the associations between socially prescribed perfectionism and irrational belief subscales were much smaller in magnitude. Self-oriented perfectionism, socially prescribed perfectionism, and irrational beliefs were all associated significantly with elevated distress among adolescents, and irrational beliefs predicted unique variance in distress, over and above the variance attributable to the trait perfectionism dimensions. The findings confirmed the association between perfectionism and irrational beliefs and their respective roles in psychological distress among adolescents.     

From Moment to Movement: Empowerment and Resilience as a Framework for Collective Action in Hong Kong

The Transconceptual Model of Empowerment and Resilience (American Journal of Community Psychology, 52, 2013, 333) suggests that a set of resilience and empowerment resources fuel both initial and sustained participation in collective action. Using the case study of a prodemocracy movement in Hong Kong, the present study focused on the subset of those resources that are relevant in ongoing collective action: efficacy, skills, and maintenance. As individuals possess varying combinations of these resources, the present study utilized latent profile analysis to test how patterns of empowerment and resilience resources influence initial and long‐term collective action. Five groups were identified: (a) Uncommitted/Uninspired; (b) Committed to Status Quo; (c) Mainstream Populist; (d) Empowered; and (e) Ambivalent. ANOVA and ANCOVA analyses found that there are significant group differences in initial and long‐term participation. Groups with higher level of resources reported greater levels of initial participation than their counterparts; however, high resource groups did not uniformly report greater levels of intention to participate in future collective action. Of the maintenance processes tested, collective identity emerged as a particularly important predictor differentiating initial and sustained participation. Findings from the present study raise questions about how individuals with multiple identities can come together and participate in collective action.     

Words Get in the Way: Linguistic Effects on Talker Discrimination

A speech perception experiment provides evidence that the linguistic relationship between words affects the discrimination of their talkers. Listeners discriminated two talkers' voices with various linguistic relationships between their spoken words. Listeners were asked whether two words were spoken by the same person or not. Word pairs varied with respect to the linguistic relationship between the component words, forming either: phonological rhymes, lexical compounds, reversed compounds, or unrelated pairs. The degree of linguistic relationship between the words affected talker discrimination in a graded fashion, revealing biases listeners have regarding the nature of words and the talkers that speak them. These results indicate that listeners expect a talker's words to be linguistically related, and more generally, indexical processing is affected by linguistic information in a top‐down fashion even when listeners are not told to attend to it.
