Vulnerability to economic stress

A stress vulnerability model was applied to the relationship between economic stress and mental health. Longitudinal data were obtained by reinterviewing 291 respondents from a prior community survey of economic change and health (Catalano & Dooley, 1983). The follow-up survey was conducted at the height of the last recession, approximately 1 year after the first. As predicted, increases in self-reported economic stress adversely affected psychological health, controlling for prior mental health status. However, individuals with poor prior mental health status were more vulnerable to economic stress: They were more likely to experience it during this economic contraction and were somewhat less likely to recover from it. Economic stress and mental health appear to have reciprocal effects, suggesting a spiral model of adaptation. Implications for interventions concerning economic change and mental health are discussed.

Cross-Lagged Relationships Between Insomnia and Posttraumatic Stress Disorder in Treatment-Receiving Veterans

Insomnia is a risk factor for the development of posttraumatic stress disorder (PTSD) while it is also plausible that PTSD symptoms can maintain insomnia symptoms. The present study examined longitudinal bidirectional relationships between insomnia and PTSD symptoms in treatment-seeking veterans. Participants were 693 ex-serving members of the Australian Defence Force who participated in an accredited, hospital-based outpatient PTSD program. Participants completed self-reported assessments of PTSD and insomnia symptoms at four time points: intake, discharge, 3-month, and 9-months posttreatment follow-up.Cross-lagged pathway analyses indicated significant bi-directional pathways between insomnia symptoms and PTSD symptoms at most time points. A final cross-lagged model between insomnia symptoms and the PTSD symptom clusters indicated that the PTSD symptom paths on insomnia symptoms, between intake and discharge, were attributable to reexperiencing PTSD symptoms. In contrast, across posttreatment follow-up time points there were significant paths of insomnia symptoms on all PTSD symptom clusters except from insomnia at 3-months to avoidance symptom at 9-months. PTSD symptoms and insomnia symptoms have bidirectional associations over time that may lead to the mutual maintenance or exacerbation of each condition following PTSD treatment. Where residual insomnia symptoms are present post-treatment, a sleep-focussed intervention is indicated and a sequenced approach to treatment recommended.     

Educated and underemployed: Refugee integration into the Canadian labour market

This study explores issues of access to high-status occupations in the Canadian labour market, with particular emphasis on refugees who were in professional or managerial positions prior to their arrival in Canada. The study is based on interviews with a sample of 525 adult refugees who were initially resettled in the province of Alberta between 1992 and 1997. About two thirds of the respondents came from former Yugoslavia, the remainder from countries in the Middle East, Central America, Africa, and Southeast Asia. Despite the generally high educational attainment of these refugees, the results show that they experience, much higher rates of unemployment, part-time employment, and temporary employment than do Canadian-born individuals. A variety of structural factors operating in a segmented Canadian labour market help to explain the downward mobility of these highly qualified refugees. The policy implications of these results are examined in detail.     

Caregiver ratings and performance-based indices of executive function among preschoolers with and without maltreatment experience

Despite the well-documented impact of early maltreatment on children’s executive function (EF), there has been limited consensus about how to best assess this neurocognitive domain in high-risk, vulnerable preschool-aged children. Relevant studies have generally utilized either performance-based tests or caregiver ratings of EF, yet multi-method research has been rare. This study examined the EF profiles of preschoolers exposed to maltreatment, as indexed by the Behavior Rating Inventory of Executive function – Preschool Version (BRIEF-P), and investigated associations between caregiver ratings and performance-based measures (Happy–Sad Stroop, Tapping Test, and Dimensional Change Card Sort – DCCS) of EF in this population. Maltreatment status was further tested as a moderator of associations between these measures. Participants were (n = 107) children aged 4–5 years (M = 4.75; SD = 0.57; 39% female), with various levels of exposure to maltreatment. Children exposed to maltreatment were found to exhibit significantly more caregiver-rated deficits in EF than non-maltreated children, with greater fluctuations apparent across all scales of the BRIEF-P. Consistent with previous research in neurologically impaired children, there were only limited and weak to moderate correlations between BRIEF-P scales and performance-based measures of EF. Furthermore, maltreatment status was found to moderate the association between scores on the BRIEF-P Inhibit Scale and the DCCS, such that the association between these indices was weaker among children exposed to higher levels of maltreatment.     

Long-Term Neuropsychological Outcomes of Childhood Onset Acute Disseminated Encephalomyelitis (ADEM): a Meta-Analysis

The long-term neurocognitive prognosis of childhood onset acute disseminated encephalomyelitis (ADEM) is unclear. This review and quantitative synthesis of the available literature examined whether there are long-term impacts of childhood ADEM on neurocognitive functioning. A search of online databases (MEDLINE, EMBASE, EBSCO CINAHL, PsycINFO and the Cochrane Database of Systematic Reviews) from their inception to October 2015 and reference lists identified 13 papers eligible for inclusion in the systematic review; seven of these were eligible for inclusion in meta-analyses. The systematic review indicated that, at a group level there is a positive long-term neuropsychological outcome from childhood onset ADEM. However, despite the apparent absence of long-term negative impacts of ADEM at a group level, at an individual level impairments in the areas of IQ, attention, executive functioning, processing speed, learning and memory, visuospatial skills and internalising symptoms were found in up to 43% of patients when aggregated across the studies. No significant negative effect of ADEM for any of the neuropsychological domains examined was found in meta-analyses. However, the effects for Processing Speed (r _mean = ?0.296 (CI 95% = ?0.605-0.013)) and Internalising symptoms (r _mean = 0.242 (CI 95% = ?0.014-0.564)) approached significance (p = 0.06), suggesting a trend towards ADEM leading to long-term reduced processing speed and elevated internalising symptoms. Together, our findings suggest that despite a generally positive neurocognitive outcome post childhood ADEM there are a subset of individuals who can suffer from ongoing specific cognitive impairments. Clinical implications and research priorities are discussed.     

The effect of stressor severity on outcome following group debriefing

This analogue study reports data on the efficacy of group debriefing in the mitigation of distress for a stressful video, which had two levels of severity. It also provides a new procedure for use in experimental psychopathology studies. One hundred and nineteen participants were shown one of two stressful videos and, subsequently, 67 participants received group debriefing whilst 52 participants acted as a control. A statistical difference was found between the two groups for level of distress at follow-up, with those who had watched the more stressful video scoring higher on video distress and trauma-type symptomatology than those who watched the less stressful video. This was particularly the case for those who received debriefing -- adding further caution to the longer-term effects of systematised group interventions following harrowing events.     

Attracting and retaining immigrants outside the metropolis: is the pie too small for everyone to have a piece? The case of Edmonton, Alberta

The municipal government of the province of Alberta’s capital city, Edmonton, commissioned a study in 2005 to determine how to attract more immigrants. City leaders were perplexed as to why Calgary, a city in the same province, of similar size with the same range of immigrant services, receives double the number of immigrants annually. In this paper, we describe the resulting study and discuss its attraction and retention recommendations. These suggestions are similar to those made by the researchers from other municipalities and regions seeking to increase their population via immigration. We compare Edmonton’s municipal and Alberta’s provincial immigration policies with those from elsewhere and discuss them in light of the national Canadian immigration policies. Given that the current federal government has no plans to increase immigration levels overall, different provinces and cities in Canada will be put in the position of having to compete for a relatively small number of newcomers, employing many of the same strategies. Without changes to federal policies, many communities may continue to struggle to attract immigrants.
