Challenge demands, hindrance demands, and psychological need satisfaction: their influence on employee engagement and emotional exhaustion

The job demands-resources (JD-R) model provides a well-validated account of how job resources and job demands influence work engagement, burnout, and their constituent dimensions. The present study aimed to extend previous research by including challenge demands not widely examined in the context of the JD-R. Furthermore, and extending self-determination theory, the research also aimed to investigate the potential mediating effects that employees' need satisfaction as regards their need for autonomy, need for belongingness, need for competence, and need for achievement, as components of a higher order needs construct, may have on the relationships between job demands and engagement. Structural equations modeling across two independent samples generally supported the proposed relationships. Further research opportunities, practical implications, and study limitations are discussed.

Effects of work-related sleep restriction on acute physiological and psychological stress responses and their interactions: A review among emergency service personnel

Emergency work can expose personnel to sleep restriction. Inadequate amounts of sleep can negatively affect physiological and psychological stress responses. This review critiqued the emergency service literature (e.g., firefighting, police/law enforcement, defense forces, ambulance/paramedic personnel) that has investigated the effect of sleep restriction on hormonal, inflammatory and psychological responses. Furthermore, it investigated if a psycho-physiological approach can help contextualize the significance of such responses to assist emergency service agencies monitor the health of their personnel. The available literature suggests that sleep restriction across multiple work days can disrupt cytokine and cortisol levels, deteriorate mood and elicit simultaneous physiological and psychological responses. However, research concerning the interaction between such responses is limited and inconclusive. Therefore, it is unknown if a psycho-physiological relationship exists and as a result, it is currently not feasible for agencies to monitor sleep restriction related stress based on psycho- physiological interactions. Sleep restriction does however, appear to be a major stressor contributing to physiological and psychological responses and thus, warrants further investigation.

Association of different forms of bullying victimisation with adolescents' psychological distress and reduced emotional wellbeing

OBJECTIVE: The frequency and emotional response to bullying victimisation are known to be associated with adolescent mental ill health. A potentially important under-investigated factor is the form of bullying. Four common forms of bullying behaviours are name-calling, physical threats or harm, rumour spreading and social exclusion. To more comprehensively understand bullying victimisation in adolescence, we examined the association of all three factors (frequency, emotional response, form) to psychological distress and emotional wellbeing. METHOD: A stratified, random sample of adolescents (n = 10, 273; mean age = 14.33 years, standard deviation = 1.68 years) completed validated measures of bullying victimisation (Gatehouse Bullying Questionnaire), psychological distress (K10) and emotional wellbeing (Mental Health Inventory) in classroom time. Associations between the form of bullying victimisation and mental health outcomes were examined. RESULTS: Adolescents reported a high prevalence of all four forms of bullying: teased or called names (30.6%), rumour spreading (17.9%), social exclusion (14.3%) and physical threats or harm (10.7%). Victimisation was independently associated with significantly higher levels of psychological distress and reduced levels of emotional wellbeing for all forms of bullying. In particular, social exclusion had a strong association with mental ill health. Adolescents who experienced frequent bullying that was upsetting reported higher psychological distress and reduced emotional wellbeing. CONCLUSION: Different forms of bullying victimisation were independently associated with psychological distress and reduced emotional wellbeing. In particular, frequent and upsetting social exclusion requires a targeted and measured response by school communities and health practitioners.

A systematic review and meta-analysis of behaviourally based psychological interventions and pharmacological interventions for trichotillomania

Background: Trichotillomania (hair-pulling disorder) is a debilitating and distressing disorder associated with great secrecy and shame. A lack of understanding regarding interventions for Trichotillomania contributes to poor routine outcomes for the disorder. Method: This systematic review and meta-analysis assessed the efficacy of behaviourally based psychological interventions and pharmacological interventions for trichotillomania compared to a range of control groups. Participants were adults who have been diagnosed with trichotillomania. A systematic search was conducted of the Cochrane library, EBSCOhost, MEDLINE before 1966, and Google Scholar for relevant randomised controlled trials. Results: Of the total 462 records identified, 12 studies were included in the quantitative synthesis, and nine studies were included in meta-analyses. Conclusions: Analyses revealed that-from medication approaches-fluoxetine was not found to be efficacious. However, N-acetyl cysteine, clomipramine, and olanzapine showed potential for the treatment of trichotillomania. Regarding psychotherapy, behaviour therapy showed superior efficacy when compared to a passive control group. However, when behaviour therapy was compared to an active control group (progressive muscle relaxation, supportive therapy), both conditions showed similar efficacy in treating trichotillomania. It was concluded that the psychological mechanisms in trichotillomania may be more complex than the behavioural model indicates. Implications and limitations are discussed.

Hypothalamo-pituitary adrenal axis and sympatho-adrenal medullary system responses to psychological stress were not attenuated in women with elevated physical fitness levels

It is not clear if higher levels of cardiorespiratory fitness are associated with lower hypothalamo-pituitary adrenal (HPA) axis and sympatho-adrenal medullary (SAM) system reactivity to psychological stress in women. The association between cardio-metabolic risk markers and acute physiological responses to psychological stress in women who differ in their cardiorespiratory fitness status has also not been investigated. Women with high (n = 22) and low (n = 22) levels of fitness aged 30-50 years (in the mid-follicular phase of the menstrual cycle) were subjected to a Trier Social Stress Test (TSST) at 1500 h. Plasma concentrations of cortisol, adrenaline (Adr), noradrenaline (NA), and dopamine (DA) were measured in samples collected every 7-15 min from 1400 to 1700 h. Heart rate and blood pressure were measured at the same time points. Low-fit women had elevated serum triglyceride, cholesterol/HDL ratio, fasting glucose, and HOMA-IR levels compared with high-fit women. While cortisol, Adr, NA, HR, and blood pressure all demonstrated a significant response to the TSST, the responses of these variables did not differ significantly between high- and low-fit women in response to the TSST. Dopamine reactivity was significantly higher in the low-fit women compared with high-fit women. There was also a significant negative correlation between VO2 max and DA reactivity. These findings suggest that, for low-fit women aged 30-50 years, the response of HPA axis and SAM system to a potent acute psychological stressor is not compromised compared to that in high-fit women.

Serving in Bosnia made me appreciate living in Bristol: stressful experiences, attitudes, and psychological needs of members of the United Kingdom Armed Forces

Peacekeeping operations form an increasing part of the role of the U.K. Armed Forces. This study identified perceived needs for training before such operations, experiences of stress during deployments, beliefs and attitudes regarding psychological support and debriefing on return, general attitudes toward peacekeeping duties, and positive aspects of the peacekeeping role. Although nearly all peacekeepers were exposed to a variety of experiences, most perceived stress came from professional difficulties and frustrations with the occupational role of being a peacekeeper, rather than from dangerous situations. The exception was a significant fear of land mines. For many, peacekeeping had a positive impact on soldiers' lives, most commonly an appreciation of "things back home." Respondents' opinions about the peacekeeping experience vary greatly. Additional training addressing and exploring potential conflicts between the traditional role of the soldier and the role of the peacekeeper may be useful.

Do military peacekeepers want to talk about their experiences? Perceived psychological support of UK military peacekeepers on return from deployment

Background: Little is known about what support the United Kingdom (UK) armed forces require when they return from operations. Aims: To investigate the perceived psychological support requirements for service personnel on peacekeeping deployments when they return home from operations and examine their views on the requirement for formal psychological debriefings. Methods: A retrospective cohort study examined the perceived psychological needs of 1202 UK peacekeepers on return from deployment. Participants were sent a questionnaire asking about their perceived needs relating to peacekeeping deployments from April 1991 to October 2000. Results: Results indicate that about two-thirds of peacekeepers spoke about their experiences. Most turned to informal networks, such as peers and family members, for support. Those who were highly distressed reported talking to medical and welfare services. Overall, speaking about experiences was associated with less psychological distress. Additionally, two thirds of the sample was in favour of a formalised psychological debriefing on return to the UK. Conclusions: This study suggests that most peacekeepers do not require formalised interventions on homecoming and that more distressed personnel are already accessing formalised support mechanisms. Additionally social support from peers and family appears useful and the UK military should foster all appropriate possibilities for such support. Declaration of Interest: The Stage 1 study was funded by the US Department of Defence (DoD) and the follow up study by the Medical Research Counsel (MRC). Neither the DoD nor MRC had any input into the design, conduct, analysis or reporting of the study. The views expressed are not those of any US or UK governmental organisation.

Female genital mutilation: cultural and psychological implications

Female genital mutilation (FGM) is widely practised in several regions of the world. It is often associated with physical, psychological, sexual and social sequelae. Migration of persons from cultures that actively practice FGM to the UK and other Western countries increases the chances that clinicians will be faced with patients who have undergone this procedure. Clinical presentations often occur against a background of differences in culture and social identity, which may pose a challenge to any form of intervention. Perceptions of normalcy, human rights violation and gender roles may also differ. This paper discusses historical, cultural, gender and identity issues associated with FGM and its psychological and sexual implications.

Economic evaluation of a psychological intervention for high distress cancer patients and carers: costs and quality-adjusted life years

OBJECTIVE: This study compared the cost-effectiveness of a psychologist-led, individualised cognitive behavioural intervention (PI) to a nurse-led, minimal contact self-management condition for highly distressed cancer patients and carers.

METHODS: This was an economic evaluation conducted alongside a randomised trial of highly distressed adult cancer patients and carers calling cancer helplines. Services used by participants were measured using a resource use questionnaire, and quality-adjusted life years were measured using the assessment of quality of life - eight-dimension - instrument collected through a computer-assisted telephone interview. The base case analysis stratified participants based on the baseline score on the Brief Symptom Inventory. Incremental cost-effectiveness ratio confidence intervals were calculated with a nonparametric bootstrap to reflect sampling uncertainty. The results were subjected to sensitivity analysis by varying unit costs for resource use and the method for handling missing data.

RESULTS: No significant differences were found in overall total costs or quality-adjusted life years (QALYs) between intervention groups. Bootstrapped data suggest the PI had a higher probability of lower cost and greater QALYs for both carers and patients with high distress at baseline. For patients with low levels of distress at baseline, the PI had a higher probability of greater QALYs but at additional cost. Sensitivity analysis showed the results were robust.

CONCLUSIONS: The PI may be cost-effective compared with the nurse-led, minimal contact self-management condition for highly distressed cancer patients and carers. More intensive psychological intervention for patients with greater levels of distress appears warranted.

Psychological wellbeing among same-sex attracted and heterosexual parents: Role of connectedness to family and friendship networks

© 2015 Australian Association of Family Therapy. Increasing numbers of lesbian, gay and bisexual (LGB) adults are entering into parenthood. Previous studies indicate many of these parents receive little or no support from their families of origin due to family members' negative attitudes toward homosexuality. This study looks at the extent to which LGB parents report a lower sense of connectedness to family of origin and friendship networks than heterosexual parents and whether this has an impact on psychological wellbeing in either of these groups. Data were derived from two studies of parents: Work, Love, Play, a study of Australian and New Zealand LGB parents (n=324); and the Longitudinal Study of Australian Children, a population-based study of young children and parents (n=6460). Structural equation modelling was used to explore the relationships between: parent sexuality and family/friendship connectedness, family/friendship connectedness and psychological wellbeing, parent sexuality and psychological wellbeing. LGB parents reported feeling less connected to their families of origin but more connected to their friendship groups than heterosexual parents. Counter to previous studies, we found no difference in the psychological wellbeing of LGB parents compared to heterosexual parents when examining the direct effect of sexuality on psychological wellbeing. Clinical implications for counsellors and family therapists are discussed.

On the potential for psychological researchers and psychologists to promote the social inclusion of people with disability: A review

© 2015 Australian Psychological Society. Objective: This paper outlines different approaches to understanding disability and describes ways in which psychological researchers and psychologists can promote the social inclusion of people with disability. Method: Narrative review drawing on writings and research from psychology and disability studies. Results: Five prominent models of disability appear in the literature (moral, medical, social, biopsychosocial, and post-modern), all of which have relevance to the lives of people with disability. Conceptualisations commonly used to understand the experience of disability from a psychological perspective include stigma and psycho-emotional disablism. There is evidence that people with disability wish to have greater involvement in research (e.g., as consultants and partners in research about them, and as participants in mainstream research) and to see research findings translated into practice. Evidence is emerging that can be used to underpin psychologists work with (a) communities (to foster social change and social justice, and to reduce stigma); (b) organisations, such as schools, workplaces, and disability service providers (to help develop inclusive and supportive environments); (c) families (to promote optimism, alternative understandings of disability, and a sense of control, as well as developing behaviour support plans and providing referrals to other sources of practical support); and (d) people with disability (to assist them with the issues they bring to therapy while being mindful of the potential for psycho-emotional disablism to colour the material presented). Conclusion: Psychological researchers and psychologists have significant potential to contribute to the social inclusion of people with disability.

How does microfinance enhance entrepreneurial outcomes in emerging economies? The mediating mechanisms of psychological and social capital

In this article, a conceptual framework and research propositions are developed to explain how microfinance provision can translate into new venture creation and existing venture growth in an emerging economy context by engendering higher levels of psychological and social capital in clients. In doing this, the extent to which microfinance institutions provide business support and opportunities for social interaction are identified as factors which may strengthen the impact of microfinance provision on psychological and social capital, especially for poor entrepreneurs in resource-constrained settings. The conceptual framework and research propositions developed will be of use to academics in designing an agenda for future empirical research. In addition, they will help policymakers and microfinance providers to better design microfinance initiatives that enhance the well-being of clients and maximise their entrepreneurial outcomes. © The Author(s) 2013.

Psychological capital: A review and synthesis

The concept of psychological capital (PsyCap) has attracted a great deal of interest from both academics and practitioners and has been linked to employee attitudes, behavior and performance at different levels of analysis. Yet, the nature of the concept, its measurement, the factors that influence its development, and when and how it influences individual-level, team-level and organizational-level outcomes are the subject of continued debate in the literature. This article offers a detailed and focused review of the existing literature on PsyCap, with the aim of developing an agenda for future research. In particular, we call for researchers to pay greater attention to possible multi-level applications of PsyCap research, examine the underlying mechanisms by which PsyCap influences individual-level, team-level and organizational-level outcomes, and identify possible factors that may moderate the relationship between PsyCap and its outcomes. In doing this, we provide a roadmap for scholars to progress the development of the field. © 2014 John Wiley & Sons, Ltd.

Autobiographical memory and depression: identity-continuity and problem-solving functions indirectly predict symptoms over time through psychological well-being

The aim of this study was to assess the longitudinal associations between adaptive autobiographical memory functions and depressive symptoms. Consistent with the proposed mechanisms of change underpinning cognitive-reminiscence therapy (CRT), it was hypothesised that more frequent adaptive reminiscence would lead to increases in psychological resources over time and indirectly affect depressive symptoms through this pathway. A sample of 171 young adults (mean age=25.9years, SD=3.5) completed measures of how frequently they utilised autobiographical memory for identity-continuity and problem-solving purposes, depressive symptoms and personal resources (self-esteem, self-efficacy, meaning in life and optimism) at two time-points. The results of structural equation modelling supported the model of indirect influence between reminiscence functions and depression through these psychological resources. These findings clarify the effects of adaptive autobiographical memory on depressive symptoms in young adults and indicate potential benefits of interventions such as CRT.
