Solitude in context: On the role of culture,immigration, and acculturation in the experience of time to oneself

Older adults spend much time in solitude (without social interaction), putting them at risk of loneliness, especially if aging outside their country of origin (e.g., Chinese immigrants to Canada). Yet, cultural contextual factors that may reduce loneliness in moments of solitude are poorly understood. This study sought to disentangle the roles of culture, immigration, and acculturation in solitude-loneliness associations across two countries. Community-dwelling adults aged 51–85 in Vancouver (N = 58 East Asian, N = 37 European/North American) and in Hong Kong (N = 56 East/Southeast Asian) completed approximately 30 ecological momentary assessments over 10 days on their current affect and social situations. Participants in Vancouver spent more time in solitude, desired solitude more, and felt less lonely overall than those in Hong Kong. Multilevel models revealed that moments of solitude felt lonelier than moments spent in social interaction, but only for individuals less acculturated to their host culture or not concurrently desiring solitude. Associations held regardless of host culture, cultural heritage, or immigration status. Findings suggest that solitude need not feel lonely if it happens by choice and if individuals feel connected with their host culture, for both immigrant older adults and those aging in their birth country.     

Transient hippocampal down-regulation of Kv1.1 subunit mRNA during associative learning in rats

Voltage-gated potassium channels (Kv) are critically involved in learning and memory processes. It is not known, however, whether the expression of the Kv1.1 subunit, constituting Kv1 channels, can be specifically regulated in brain areas important for learning and memory processing. Radioactive in situ hybridization was used to evaluate the content of Kv1.1 α-subunit mRNA in the olfactory bulb, ventral, and dorsal hippocampus at different stages of an odor-discrimination associative task in rats. Naive, conditioned, and pseudoconditioned animals were sacrificed at different times either prior to a two-odor significance learning or after odor discrimination was established. Important decreases of Kv1.1 mRNA levels were transiently observed in the ventral hippocampus before successful learning when compared with the pseudoconditioned group. Moreover, temporal group analysis showed significant labeling alterations in the hippocampus of conditioned and pseudoconditioned groups throughout the training. Finally, Kv1.1 mRNA levels in the hippocampus were positively correlated with odor-reward association learning in rats that were beginning to discriminate between odors. These findings indicate that the Kv1.1 subunit is transiently down-regulated in the early stages of learning and suggest that Kv1 channel expression regulation is critical for the modification of neuronal substrates underlying new information acquisition.     

Comorbidity and Related Factors Among Ethnically Diverse Substance Using Pregnant Women

Studies have established that comorbidity needs to be considered when assessing and treating substance-using clients. This study explores course of treatment, risk factors, and drug-related issues among 192 ethnically diverse pregnant women who were actively using drugs at admission to a residential treatment program. Findings revealed that course of treatment is more difficult for comorbid clients who perceived more treatment barriers than noncomorbid clients. Comorbid clients were more likely to have a history of attempting suicide but no more likely to have been reported for child abuse or charged with a crime. Comorbid clients reported greater severity of alcohol use but did not differ from noncomorbid clients regarding drug of choice. Comorbid clients were no more likely to leave against treatment advice, and noncomorbid clients were no more likely to complete treatment. Findings suggest that sensitivity to comorbidity issues is crucial to retaining comorbid clients in treatment.     

The Caring‐Killing Paradox: Euthanasia‐Related Strain Among Animal‐Shelter Workers1

The current study represents the first quantitative investigation of the psychological ramifications of euthanasia‐related work. Results indicate that perceived euthanasia‐related strain is prevalent among shelter employees and is associated with increased levels of general job stress, work‐to‐family conflict, somatic complaints, and substance use; and with lower levels of job satisfaction. Analyses provide evidence that euthanasia‐related work has a significant negative relation with employee well‐being independent of its relation with generalized job stress. Exploratory analyses also suggest that individual, work, and organizational differences may influence the level of perceived stress and appear to be associated with certain aspects of employee well‐being. The need for future research of this topic and its relevance to a wide range of applied psychologists is discussed.     

Social and emotional self‐efficacy at work

Research has shown that self‐efficacy is often one of the most important personal resources in the work context. However, because this research has focused on cognitive and task‐oriented self‐efficacy, little is known about social and emotional dimensions of self‐efficacy at work. The main aim of the present study was to investigate social and emotional self‐efficacy dimensions at work and to compare them to a cognitive and task‐oriented dimension. Scales to measure social and emotional self‐efficacy at work were developed and validated and found to be well differentiated from the cognitive task‐oriented occupational self‐efficacy scale. Confirmatory factor analyses of data from 226 Swedish and 591 German employees resulted in four separate but correlated self‐efficacy dimensions: (1) occupational; (2) social; (3) self‐oriented emotional; and (4) other‐oriented emotional. Social self‐efficacy explained additional variance in team climate and emotional self‐efficacy in emotional irritation and emotional exhaustion, over and above effects of occupational self‐efficacy. Men reported higher occupational self‐efficacy, whereas social and emotional self‐efficacy revealed no clear gender differences. The scales have strong psychometric properties in both Swedish and German language versions. The positive association between social self‐efficacy and team climate, and the negative relationships between self‐oriented emotional self‐efficacy and emotional irritation and emotional exhaustion may provide promising tools for practical applications in work settings such as team‐building, staff development, recruitment or other training programs aiming for work place health promotion. The next step will be to study how social and emotional self‐efficacy relate to leadership, well‐being and health over time.
