Prenatal depression is a significant predictor of postpartum depression and is detrimental to fetal development. Locus of control was examined in this study as a potential predictor of prenatal depression. 133 rural pregnant women recruited from obstetricians’ offices completed the Levenson Scale on Locus of Control and the Edinburgh Postnatal Depression Scale. Multiple regression analysis indicated that after controlling for previous or current mental health problems, the External Locus of Control-Chance Scale accounted for 17% of the variance in depression scores
Purpose: In the aphasia literature, motivation has been described as potentially influencing rehabilitation outcomes, and there are reports that researchers and clinicians have acted to promote it. However, studies directly investigating the range of beliefs and practices surrounding motivation do not exist currently. The purpose of this scoping review is to develop themes related to the beliefs and practices appearing in the recent aphasia literature. Method: Four databases (CINAHL, PsycINFO, PubMed, and Google Scholar) were searched using keywords aphasia and motivation (including derivatives such as motiv*) for articles published between 2009 and 2020. Searches returned 19,731 articles; after deleting duplicates and applying inclusionary criteria, 365 articles remained. In each article, text surrounding the term motivation was highlighted and thematic analysis was applied to these quotations. Results: Sixteen themes were developed through thematic analysis and placed into two groups. The first group contained five themes suggesting that researchers believed that motivation should be studied and recognized the value of motivation in person(s) with aphasia when participating in research or clinical activities. The second group contained 11 themes reporting diverse beliefs and practices in how motivation is incorporated in research and clinical activities. Conclusions: Results from this scoping review suggest that aphasia researchers, clinicians, and persons with aphasia hold beliefs about motivation that can influence clinical and research decisions. In general, beliefs and decisions related to motivation appeared to be guided by intuition rather than theories of motivation. These themes are discussed within the context of three psychological needs proposed by self-determination theory: competency, autonomy, and relatedness. Applying theories of motivation to future study in aphasia rehabilitation will guide work that can provide empirical support for these beliefs.
IntroductionApraxia of speech (AOS) is a motor speech disorder impairing the coordination of complex articulatory movements needed to produce speech. AOS typically co-occurs with a non-fluent aphasia, or language disorder, making it challenging to determine the specific brain structures that cause AOS. Cases of pure AOS without aphasia are rare but offer the best window into the neural correlates that support articulatory planning. The goal of the current study was to explore patterns of apraxic speech errors and their underlying neural correlates in a case of pure AOS.MethodsA 67-year-old right-handed man presented with severe AOS resulting from a fronto-insular lesion caused by an ischemic stroke. The participant’s speech and language were evaluated at 1-, 3- and 12-months post-onset. High resolution structural MRI, including diffusion weighted imaging, was acquired at 12 months post-onset.ResultsAt the first assessment, the participant made minor errors on the Comprehensive Aphasia Test, demonstrating mild deficits in writing, auditory comprehension, and repetition. By the second assessment, he no longer had aphasia. On the Motor Speech Evaluation, the severity of his AOS was initially rated as 5 (out of 7) and improved to a score of 4 by the second visit, likely due to training by his SLP at the time to slow his speech. Structural MRI data showed a fronto-insular lesion encompassing the superior precentral gyrus of the insula and portions of the inferior and middle frontal gyri and precentral gyrus. Tractography derived from diffusion MRI showed partial damage to the frontal aslant tract and arcuate fasciculus along the white matter projections to the insula.DiscussionThis pure case of severe AOS without aphasia affords a unique window into the behavioral and neural mechanisms of this motor speech disorder. The current findings support previous observations that AOS and aphasia are dissociable and confirm a role for the precentral gyrus of the insula and BA44, as well as underlying white matter in supporting the coordination of complex articulatory movements. Additionally, other regions including the precentral gyrus, Broca’s area, and Area 55b are discussed regarding their potential role in successful speech production.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
