Depressive symptoms during pregnancy: impact on neuroendocrine and neonatal outcomes

Objective

To explore the interplay of maternal depressive symptoms on the infant limbic-hypothalamic-pituitary axis (LHPA) and neurological development.

Design

Pregnant women were monitored for depressive symptoms using the Beck Depression Inventory (BDI) at 28, 32, and 37 weeks of gestation and at delivery. A mixture growth curve analysis divided the women into three risk groups: low/stable, intermediate, and high/increasing depression based on BDI scores. The infant neuroendocrine system was examined using cord blood for adrenocorticotrophic hormone (ACTH) and cortisol measurements. Two-week-old infants were examined using Neonatal Intensive Care Unit Neurobehavioral Scale (NNNS).

Results

Infants born to women of the high/increasing depression group had significant ACTH elevation at birth. On NNNS examination, these infants were more hypotonic and habituated to auditory and visual stimuli.

Conclusion

When compared to non-depressed women, maternal depressive symptoms, even in the absence of major depressive disorder, appeared to facilitate a different developmental pathway for the infant LHPA and early neurological development.     

Exploring outcomes through narrative: the long-term impacts of Better Beginnings, Better Futures on the turning point stories of youth at ages 18-19

This study examined the long-term effects of the Better Beginnings, Better Futures project, a community-based early childhood development program, on 18–19 year-old youths’ narratives about turning points in their lives. The sample consisted of youth who participated in Better Beginnings from ages 4–8 (n = 62) and youth from a comparison community who did not participate in Better Beginnings (n = 34). Controlling for covariates, significant differences favoring youth from the Better Beginnings sites were found on several dimensions of the turning point stories: ending resolution, personal growth, meaning-making, coherence, and affect transformation. Effect sizes ranged from .45 to .76 for these outcome dimensions, indicating moderate to large effects. Also, turning point story dimensions were found to be significantly correlated with two standardized measures of well-being: youths’ self-esteem and community involvement. Youths’ self-esteem was directly related to story ending resolution, personal growth, and meaning making, and youths’ community involvement was directly related to story specificity, meaning making, and coherence. Family functioning was also examined in relation to these narrative dimensions but was not found to be significantly related to them. The findings suggest the utility of a narrative approach for the evaluation of the long-term outcomes of early childhood development programs.     

消费者决策分析的新视角:双通道心理账户理论

双通道心理账户是指人们在购买决策时具有一个双向通道的心理账户,其中一个通道记录了付款后消费者剩余的正效用,而另一个通道则记录了除去消费后付款带来的负效用.当消费与支付联结紧密时,会让人们更易想起支付的痛苦,从而降低消费快感,此时快乐弱化系数(α)大;当消费与支付联结较弱时,人们更不易记起支付的金额,从而在消费时拥有更多快乐,此时痛苦钝化系数(β)大.文章通过整理已有研究发现:先付款后消费的α系数更小,而先消费后付款的β系数更小;奢侈品的α系数更大,而必需品的β系数更大;吝啬者的α系数更大,而挥霍者的β系数更大.文章进一步阐述了影响消费者购买联结的心理机制是债务规避和负的时间偏好、支付贬值等.在此基础上为消费者做出购买决策以及商家选择促销方式提出了建议.同时也为消费者决策行为研究提供了新的视角和研究课题.     

A Brief Pause between a Tagline and Brand Increases Brand Name Recognition and Preference

This paper explores the outcome of the visual encoding of brands in meaningful sentences (i.e. in taglines) on brand name recognition and preference. In this paper, it is shown that, above and beyond the role of conceptual priming during encoding at increasing recognition memory, there is a role of creating a temporal delay, or pause, between meaningful cues in the sentence and a key word (Experiment 1) or brand (Experiments 2a and 3) on memory. The pause is also associated with increased preference towards brands (Experiment 2b). These findings demonstrate a new way to enhance recognition of brand names that is not due to a pure generation effect but rather by increasing attention, which increases processing fluency of the target.

Consumer susceptibility to interpersonal influence in Mainland China

To validate the consumer susceptibility to interpersonal influence (SUSCEP) scale in China, questionnaires were administered to 1114 adult employees and 350 university students. Confirmatory factor analyses showed that the consumer susceptibility to interpersonal influence scale had a stable three‐factor structure (i.e. the utilitarian, value‐expressive, and informational dimensions) in both samples, while the original two‐factor structure could not be retrieved. Using Chinese samples, the consumer susceptibility to interpersonal influence scale and its three sub‐scales demonstrated acceptable internal reliability, as well as convergent and discriminant validity. Positive correlations between the consumer susceptibility to interpersonal influence scale (as well as its sub‐scales) and attention to social comparison information also indicated good convergent validity. The distinction between utilitarian dimension and value‐expression dimension in Chinese samples as well as the non‐significant correlations of the utilitarian dimension with self‐esteem and the informational dimension with self‐esteem revealed cultural differences between the East and the West.     

Chinese consumer ethnocentrism: A field experiment

Consumer ethnocentrism presents barriers for internationalising organisations. In China, evidence of a resurgent nationalism partly fuelled by rapid economic growth portends a shift in consumption away from foreign towards domestic products. On the other hand, rising consumer demand for branded and luxury products cannot be fully met domestically. However, much of the available evidence on Chinese consumer ethnocentrism is anecdotal and is based on attitudinal surveys that, as accurate measures of actual purchasing behaviour, suffer from certain methodological issues. In response, we report an experiment that measures the ethnocentrism of 447 Chinese consumers as their incentive‐compatible choices between foreign and domestic products in a field setting. Our findings show little effect of foreign origin on subjects' choices that were only weakly related with attitudinal measures including the commonly used consumer ethnocentric tendencies scale (CETSCALE). Our results question the existence of ethnocentric consumer behaviour in China and the use of CETSCALE to gauge it generally. Copyright © 2012 John Wiley & Sons, Ltd.     

Development and validation of the consumer disillusionment toward marketing activity scale

This study examines disillusioned consumers. The theory proposes that this is a group learning to lower their expectations of firm integrity and who, to avoid being let down, ignore marketing activity directly from the firm. This kind of exchange orientation develops as a response to consistent failure in perceptions of firm integrity. The research includes six studies, including over 600 adult consumers, to outline the development and validation of a measure of consumer disillusionment toward marketing activity. Completing the process provides a valid and reliable four‐item measure. In addition, the study includes the assessment of the nomological validity of the construct. The nomological validation includes using cue utilization theory to predict that disillusioned consumers favor advertising that provides evidence of verifiable integrity. The validation experiment uses print advertising containing high and low verifiable integrity stimuli. Results confirm the theory with disillusioned consumers focusing less on the firm as source of information. Further, these consumers respond more favorably than non‐disillusioned consumers to third party endorsers who serve to verify the firm's attempts to show integrity.

A joint modeling framework of responses and response times to assess learning outcomes

Abstract

A general modeling framework of response accuracy and response times is proposed to track skill acquisition and provide additional diagnostic information on the change of latent speed in a learning environment. This framework consists of two types of models: a dynamic response model that captures the response accuracy and the change of discrete latent attribute profile upon factors such as practice, intervention effects, and other latent and observable covariates, and a dynamic response time model that describes the change of the continuous response latency due to change of latent attribute profile. These two types of models are connected through a parameter, describing the change rate of the latent speed through the learning process, and a covariate defined as a function of the latent attribute profile. A Bayesian estimation procedure is developed to calibrate the model parameters and measure the latent variables. The estimation algorithm is evaluated through several simulation studies under various conditions. The proposed models are applied to a real data set collected through a spatial rotation diagnostic assessment paired with learning tools.     

Occupational Therapy Interventions in Mental Health: A Literature Review in Search of Evidence

A growing body of literature sheds light on occupational therapy (OT) interventions and outcomes in adult mental health. Although this research has not developed to the point where a systematic review is warranted, a synthesis of these findings is needed. This article provides an overview of OT interventions in adult mental health and their documented outcomes. Fifty peer-reviewed intervention studies targeting adults with mental illness were reviewed. Seven categories of interventions emerged: employment/education; psychoeducation; creative occupations/activity; time use/occupational balance; skills/habit development; group/family approaches; and animal-assisted therapy. Further research involving rigorous designs is needed to establish a solid evidence base for OT interventions in adult mental health.
