Optimism and Mental Health in Adolescence: a Prospective Validation Study of the Dutch Life-Orientation Test-Revised (LOT-R-A) for Adolescents

The study aimed to examine the psychometric properties of the Dutch Life Orientation Test-Revised for Adolescents (LOT-R-A), a self-report questionnaire assessing dispositional optimism, and to evaluate the two-factor structure (optimism, pessimism). The LOT-R-A and the questionnaires measuring well-being (MHC-SF-A) and psychological problems (SDQ) were completed by 459 Dutch adolescents (178 boys and 281 girls) between the ages of 11 and 18 years at baseline and 281 adolescents at a four-week follow-up. The results confirmed the two-factor structure (optimism, pessimism) of the LOT-R-A. The findings provided evidence of internal consistency of scores ranging from low to good, and evidence of good test-retest reliability of scores. Further, scores of optimism were cross-sectionally positively associated with scores of positive emotions and well-being and negatively with scores of psychological problems and negative emotions, providing evidence of convergent and divergent validity of optimism scores with emotions, well-being, and psychological problems. Lastly, scores of optimism were prospectively positively associated with scores of well-being and negatively with scores of psychological problems, providing evidence of criterion validity of optimism scores with well-being and psychological problems. Based on these findings it can be concluded that the LOT-R-A is a valid instrument to examine optimism among adolescents. Future research can help to elucidate the role of optimism in mental health interventions and can gather knowledge on how these interventions can be refined to optimally cultivate optimism during the developmental period of adolescence.     

Blurring of emotional and non-emotional memories by taxing working memory during recall

Memories that are recalled while working memory (WM) is taxed, e.g., by making eye movements (EM), become blurred during the recall + EM and later recall, without EM. This may help to explain the effects of Eye Movement and Desensitisation and Reprocessing (EMDR) in the treatment of post-traumatic stress disorder (PTSD) in which patients make EM during trauma recall. Earlier experimental studies on recall + EM have focused on emotional memories. WM theory suggests that recall + EM is superior to recall only but is silent about effects of memory emotionality. Based on the emotion and memory literature, we examined whether recall + EM has superior effects in blurring emotional memories relative to neutral memories. Healthy volunteers recalled negative or neutral memories, matched for vividness, while visually tracking a dot that moved horizontally (“recall + EM”) or remained stationary (“recall only”). Compared to a pre-test, a post-test (without concentrating on the dot) replicated earlier findings: negative memories are rated as less vivid after “recall + EM” but not after “recall only”. This was not found for neutral memories. Emotional memories are more taxing than neutral memories, which may explain the findings. Alternatively, transient arousal induced by recall of aversive memories may promote reconsolidation of the blurred memory image that is provoked by EM.     

Development of Cognitive Skills in Children with Motor Coordination Impairments at 12-Month Follow-up

The current study presents a 1-year follow-up investigation of the development of executive functions (i.e., inhibition, updating, and shifting) in children with motor coordination impairments. Cognitive and motor coordination skills of children (N = 94) aged between 5 and 7 years with and without motor coordination impairments were compared. A second focus of the study was on pre-academic skills. The results indicate marked stability of motor coordination impairments and persistent executive functioning deficits in motor-impaired children. Inhibition and shifting performance was consistently lower, compared to the children without motor coordination impairments. Moreover, children with motor coordination impairments showed lower pre-academic skills, facing a substantial disadvantage at the beginning of formal schooling. The combined cognitive and motor problems may be the result of an underlying inhibition deficit or a general automation deficit. Implications for intervention are discussed.     

(Dis)armed friendship: impacts of colonial ideology on early Quaker attitudes toward American Indians

Quakers’ early relations with American Indians (especially the Lenne Lenape, later known as the Delaware Indians) were generally positive. Core Quaker principles were simplicity, integrity, equality and peace – principles that could coincide well with those of the similarly egalitarian Lenne Lenape, who had been designated peacekeepers by the Iroquois Confederacy. Although the relationship was different than that of other settlers and American Indians, it was still suffused with colonial ideology. From the founding of Pennsylvania to the period of Grant’s ‘Peace Policy’, Quakers had to negotiate two wars and changing attitudes to North American Indians by American Presidents and government. The paper focuses on corresponding shifts in Quaker attitudes and policies. Our interest is in Quaker responses to Native Americans over time, finding that Quakers became increasingly distanced from the Indians and focused on acculturation. In their zeal to become acceptable to American Governments and through that, assist Native Americans, Quakers had, in fact, assimilated themselves.     

Bullying and harassment at work and their relationships to work environment quality: An exploratory study

Team-based working has become a popular model of work organization. One of the expected yields of working in teams is collective learning. As team members work closely together they are likely to exchange information, which can enhance learning. One of the processes that may facilitate team learning is team conflict. In this study, 471 respondents, working in 84 teams in 38 organizations, indicated their perceptions of task conflict, relationship conflict, team learning, and their rating of the performance of the team. Task conflict was not related to team learning but was negatively related to the team members' rating of team performance. As was hypothesized, relationship conflict negatively affected team learning. Importantly, team learning was a strong predictor of the perceived team performance and partially mediated the relation between relationship conflict and performance.     

A model‐based intervention for depressed mothers and their infants

Many studies have reported on the adverse effects of maternal depression on offspring. Infants of depressed mothers are found to be more likely at risk to develop mental and socioemotional problems. In this study, an early intervention program is presented that aims to improve the interaction between depressed mothers and their infants to prevent developmental problems in the children. The program has recently been introduced in the Dutch Community Mental Health Centers as part of a national multicomponent program to reduce the risk of psychiatric and social problems in the offspring of parents with a mental disorder. The intervention for depressed mothers with babies is based on a transactional model in which the mother–child interaction plays a key role in explaining the development of socioemotional problems in the children. The model as discussed in the first part of this article addresses a range of evidenced‐based parental, child, and contextual risk factors that effect the quality of the interactions between depressed mothers and their infants and that contribute to both vulnerability and resilience of the children during later childhood and adolescence. ©2005 Michigan Association for Infant Mental Health.     

Dominance as Expressed and Inferred Through Speaking Time

Differences in speaking time during a group interaction are hypothesized to reflect differences in individual dominance. In order to test this assumption and to identify potential moderator variables influencing the strength of the predicted association, a meta‐analysis was conducted. Whether speaking time is used to convey dominance to the same extent that it is used in inferring dominance was tested by contrasting studies concerned with dominance expressed in speaking time with studies of inferred dominance based on speaking time. Overall, and for the investigated subcategories of studies, the relationship between dominance and speaking time was significant. The strength of the associations, however, differed considerably due to the influence of moderator variables. The results showed that inferred dominance studies showed stronger associations between speaking time and dominance as opposed to the expressed dominance studies. Additionally, if dominance was expressed due to dominance‐role assignments, the association between speaking time and dominance was stronger than if individuals with different levels of trait dominance interacted. For men, the association between speaking time and dominance was stronger than for women, and same‐gender groups showed stronger associations than opposite‐gender groups. Also, increasing group size intensified the strength of the association linearly.     

Certifying clinical ethics consultants: who pays?

The movement advocating the formal certification of clinical ethics consultants may result in major changes to the field of clinical ethics consultation by creating a new standard of care. The actual certification process is still in the development phase, but unanswered questions include: What will certification cost, and, Who will pay? Currently there is little salary support for ethics consultants and no regulation requiring healthcare institutions to offer clinical ethics consultation. Without the support of healthcare administrators and accreditation bodies, this may remain unchanged. Healthcare administrators may be unwilling to pay for certification or professional services if accreditation bodies do not require healthcare institutions to provide certified ethics consultants' services. If consultants will not be reimbursed or paid, they may not seek certification. If certified consultants are required, healthcare administrators may look for ways to cover the costs for providing this service, including insurance or third-party reimbursement and direct billing of patients for consultations, which may affect who performs and who participates in ethics consultation. However, this is less than ideal, as bioethicists believe ethics consultation should be available to all as part of providing safe, quality ethical care and support and guidance for patients, families, and healthcare staff. Going forward, bioethicists should study quality improvement, patient safety, and cost-savings resulting from certification-eligible clinical ethics consultants' activities. Administrators and financial personnel can be surveyed regarding their support for the certification process. Bioethicists should enlist the help of patient rights and safety advocacy groups, professional medical associations, and healthcare administrators. Bioethicists should invite accreditation bodies, healthcare administrators, and financial personnel to collaborate in the development of the certification process. Without their support, certification may be of value only to the bioethics community, and may have little standing in actual clinical healthcare institution settings.     

Updating process of internal model of action as assessed from motor and postural strategies in young adults

Internal models are constantly updated based on the actions and experiences of a person in the world. In the present study, we proposed to assess the updating process of internal models of action by providing new environmental constraints for motor planning, postural control, and execution processes in daily tasks such as STS and BTS. STS and BTS tasks were performed with different inclinations of the support surface on which the participant and the chair were positioned: horizontal support, support tilted 10° to the right, or forward. Twelve healthy adults participated in this experiment. Kinematic characteristics were recorded using an optoelectronic motion analysis system. Movement duration and trunk inclination amplitudes were analyzed for STS and BTS as well as trunk orientation and strategies of head stabilization. Concerning the movement analysis our results showed (1) temporal asymmetry between STS and BTS, attributed mainly to the integration of the mechanical effects of gravity, and (2) a decrease of trunk movements when the support was tilted forward, attesting to an immediate adaptation process. Concerning the postural analysis our study revealed that adults adopted selective head stabilization on space strategy with respect to balance constraints. To conclude, young adults were able to immediately update their internal model of action in order to optimize motor control and vertical body orientation.
