The multidimensional nature of resilience to spousal loss.

ABSTRACT: Spousal loss can be one of the most devastating events to occur across one's life, resulting in difficulties across different spheres of adjustment; yet, past research on resilience to bereavement has primarily focused on single adjustment indicators. We applied growth mixture modeling to data from 421 participants from the Household Income and Labour Dynamics of Australia Study who experienced spousal loss during the course of the study to examine (a) the extent to which individuals appear to be resilient across 3 indicators of subjective well-being-life satisfaction, negative affect, and positive affect, and 2 indicators of health-perceptions of general health and physical functioning-and (b) factors that might promote resilience. Approximately 66%, 19% and 26% individuals showed resilient trajectories, respectively, for life satisfaction, negative affect, and positive affect, whereas 37% and 28% showed resilience, respectively, for perceptions of general health and physical functioning. When we considered all 5 indicators simultaneously, only 8% showed "multidimensional" resilience, whereas 20% showed a non-resilient trajectory across all 5 indicators. The strongest predictors of resilient trajectories were continued engagement in everyday life activities and in social relationships, followed by anticipation that people would comfort them in times of distress. Overall, our findings demonstrate that resilience in the face of spousal bereavement is less common than previously thought. More importantly, they underscore the critical importance of multidimensional approaches while operationalizing doing well in the context of serious life adversities. (PsycINFO Database Record

Project description:Language is not a single function, but instead results from interactions between neural representations and computations that can be damaged independently of each other. Although there is now clear evidence that the language profile in post-stroke aphasia reflects graded variations along multiple underlying dimensions ('components'), it is still entirely unknown if these distinct language components have different recovery trajectories and rely on the same, or different, neural regions during aphasia recovery. Accordingly, this study examined whether language components in the subacute stage: (i) mirror those observed in the chronic stage; (ii) recover together in a homogeneous manner; and (iii) have recovery trajectories that relate to changing activation in distinct or overlapping underlying brain regions. We analysed longitudinal data from 26 individuals with mild-moderate aphasia following left hemispheric infarct who underwent functional MRI and behavioural testing at ∼2 weeks and ∼4 months post-stroke. The language profiles in early post-stroke aphasia reflected three orthogonal principal components consisting of fluency, semantic/executive function and phonology. These components did not recover in a singular, homogeneous manner; rather, their longitudinal trajectories were uncorrelated, suggesting that aphasia recovery is heterogeneous and multidimensional. Mean regional brain activation during overt speech production in unlesioned areas was compared with patient scores on the three principal components of language at both the early and late time points. In addition, the change in brain activation over time was compared with the change on each of the principal component scores, both before and after controlling for baseline scores. We found that different language components were associated with changing activation in multiple, non-overlapping bilateral brain regions during aphasia recovery. Specifically, fluency recovery was associated with increasing activation in bilateral middle frontal gyri and right temporo-occipital middle temporal gyrus; semantic/executive recovery was associated with reducing activation in bilateral anterior temporal lobes; while phonology recovery was associated with reducing activation in bilateral precentral gyri, dorso-medial frontal poles and the precuneus. Overlapping clusters in the ventromedial prefrontal cortex were positively associated with fluency recovery but negatively associated with semantic/executive and phonology recovery. This combination of detailed behavioural and functional MRI data provides novel insights into the neural basis of aphasia recovery. Because different aspects of language seem to rely on different neural regions for recovery, treatment strategies that target the same neural region in all stroke survivors with aphasia might be entirely ineffective or even impair recovery, depending on the specific language profile of each individual patient.
