Short-term memory impairment in vestibular patients can arise independently of psychiatric impairment,fatigue, and sleeplessness

Vestibular dysfunction is associated with visual short-term memory impairment; however, it remains unclear if this impairment arises as a direct result of the vestibular dysfunction or is a consequence of comorbid changes in mood, affect, fatigue, and/or sleep. To this end, we assessed the concurrence and interdependence of these comorbidities in 101 individuals recruited from a tertiary balance clinic with a neuro-otological diagnosis. Over fifty per cent of the sample showed reduced visuospatial short-term memory, 60% and 37% exceeded cut-off on the Beck Anxiety and Depression Inventories, respectively, 70% exceeded cut-off on the Fatigue Severity Scale, 44% reported daytime sleepiness on the Epworth Sleepiness Scale, and 78% scored above cut-off on the Pittsburgh Sleep Quality Index. The high concurrence of these symptoms gives reason to infer the existence of a vestibular cognitive affective syndrome. Structural equation modelling indicated that the significant statistical association between general unassisted posture (a marker of chronic vestibular dysfunction and strong predictor of falls risk) and short-term memory was not mediated by mood and wakefulness. Instead, the memory impairment related more directly to vestibular dysfunction. From a rehabilitation perspective, the implication is that if the vestibular disorder is treated successfully then the memory problem will likewise improve.

Intelligence, Callous-Unemotional Traits, and Antisocial Behavior

Research has consistently shown that children with severe conduct problems often exhibit intellectual deficits, especially in their verbal abilities. We investigated whether or not this finding only applies to certain subgroups of children with severe conduct problems. In a sample of 117 clinic-referred children between the ages of 6 and 13, we assessed for Oppositional Defiant Disorder (ODD) and Conduct Disorder (CD) symptoms using a structured diagnostic interview with each child's parent and teacher, callous and unemotional traits using parent and teacher ratings, and intellectual functioning using a standard individually administered intelligence test. Children with an ODD or CD diagnosis who did not show callous and unemotional traits showed a deficit on subtests measuring verbal reasoning ability relative to a clinic control group. Children with an ODD or CD diagnosis who also showed callous and unemotional traits did not show a verbal deficit and, in fact, showed a trend toward having weaker nonverbal abilities. These results highlight the importance of recognizing distinct subgroups of children with severe conduct problems when studying potential intellectual deficits in these children.     

Enrichment and Stress in Families Caring for a Child with a Serious Emotional Disorder

We examined enrichment and stress in 214 families who had children with severe emotional disorders. Caregivers' ratings of enrichment and stress were obtained through a newly developed instrument, the Effects of the Situation Questionnaire, which used parallel items covering 17 life areas. While ratings of stress were generally higher than enrichment, caregivers reported some enrichment in areas encompassing self concept and family relationships, Bivariate and multivariate analyses using various child, family, and service-system variables revealed that stress was notably associated with severity of the child's disorder, low empowerment, and a lack of coordination among service providers. Enrichment was unrelated to severity but associated with high empowerment and spiritual support. Our findings suggest that families' experiences of caregiving can have both positive and negative aspects and that a comprehensive approach to serving and studying families should take both into account.     

Linguistic and emotional-valence characteristics of reading passages for clinical use and research

PurposeFluency assessment in people who stutter (PWS) includes reading aloud passages. There is little information on properties of these passages that may affect reading performance: emotional valance, arousal, word familiarity and frequency and passage-readability. Our first goal was to present an extensive examination of these factors in three commonly used (“traditional”) passages. The second goal was to compare a traditional passage to a new passage, designed to minimize the impact of these properties.MethodsContent words were rated (129 participants) on arousal, valence and familiarity. Other linguistic features were analyzed based on available datasets. This information was used to assess traditional passages, and to construct a new well-balanced passage, made of neutral, low-arousal and highly-familiar words. Readability for all passages was tested using formula-based and CLOZE tests (31 participants). Finally, 26 PWS were evaluated on fluency comparing the commonly used “Rainbow” passage with the novel one.ResultsThe three traditional passages contain a share of emotionally valenced (22-34%), high arousal (15-18%), lower familiarity (6-8%) and polysyllabic (5-9%) content words. Readability was highest for the novel passage (on formula-based scales). Average disfluencies percent for the Rainbow and our novel passage were not significantly different. Yet half of the individuals in this sample showed a large difference between the two passages.ConclusionWe provide detailed information on potential sources of variance using the traditional passages. Knowledge about these characteristics can inform clinical practice (and research). We suggest a combined procedure, using more than one passage to assess stuttering in individual cases.     

青少年抑郁情绪的发展轨迹:界定亚群组及其影响因素

本研究意在分性别考察中国青少年抑郁情绪的发展轨迹及其影响因素。785名男生和859名女生参加了3轮追踪研究,初始测量阶段的年龄跨度为10~16岁,平均年龄分别为12.99±1.84和12.96±1.87岁。采用流调中心抑郁量表(CES-D)简版测量青少年的抑郁情绪。模型拟合的结果显示男女生的抑郁情绪在10~19岁时段皆呈线性增长趋势,其中男生分为两个亚群组,人际关系解释了部分变异;女生分为4个亚群组,学业压力和人际关系均解释了部分变异。     

On the Integration of Need‐related Autobiographical Memories among Late Adolescents and Late Adults: The Role of Depressive Symptoms and Self‐congruence

Within self‐determination theory, integration denotes the process through which people accept past and present experiences and harmonize these experiences within their sense of self. We investigated associations between indicators of successful and poor integration of need‐related memories and memory‐related affect. We also examined the role of depressive symptoms and self‐congruence as antecedents of these indicators. Moreover, we investigated whether late adults, compared with late adolescents, were better capable of integrating need‐frustrating memories through higher levels of self‐congruence. Participants were 132 late adolescents (Mage = 17.83) and 147 late adults (Mage = 76.13), who reported on their level of depressive symptoms and self‐congruence. Next, participants generated a need‐satisfying and need‐frustrating memory and reported on the memories' integration (in terms of acceptance, connection and rumination) and associated affect. Whereas depressive symptoms related mainly to the poor integration of need‐frustrating memories, self‐congruence related positively to the integration of both need‐satisfying and need‐frustrating memories. In turn, integration was related to more positive and less negative affect. Late adults scored higher than late adolescents on the integration of need‐frustrating memories, an effect that was partly accounted for by late adults' elevated self‐congruence. Results suggest that self‐congruence, depressive symptoms and age play a role in the integration of need‐based autobiographical memories.
