Predicting mid-life capital formation with pre-school delay of gratification and life-course measures of self-regulation.

How well do pre-school delay of gratification and life-course measures of self-regulation predict mid-life capital formation? We surveyed 113 participants of the 1967-1973 Bing pre-school studies on delay of gratification when they were in their late 40's. They reported 11 mid-life capital formation outcomes, including net worth, permanent income, absence of high-interest debt, forward-looking behaviors, and educational attainment. To address multiple hypothesis testing and our small sample, we pre-registered an analysis plan of well-powered tests. As predicted, a newly constructed and pre-registered measure derived from preschool delay of gratification does not predict the 11 capital formation variables (i.e., the sign-adjusted average correlation was 0.02). A pre-registered composite self-regulation index, combining preschool delay of gratification with survey measures of self-regulation collected at ages 17, 27, and 37, does predict 10 of the 11 capital formation variables in the expected direction, with an average correlation of 0.19. The inclusion of the preschool delay of gratification measure in this composite index does not affect the index's predictive power. We tested several hypothesized reasons that preschool delay of gratification does not have predictive power for our mid-life capital formation variables.

Observation-Oriented Modeling: Going Beyond "Is It All a Matter of Chance"?

An alternative to null hypothesis significance testing is presented and discussed. This approach, referred to as observation-oriented modeling, is centered on model building in an effort to explicate the structures and processes believed to generate a set of observations. In terms of analysis, this novel approach complements traditional methods based on means, variances, and covariances with methods of pattern detection and analysis. Using data from a previously published study by Shoda et al., the basic tenets and methods of observation-oriented modeling are demonstrated and compared with traditional methods, particularly with regard to null hypothesis significance testing.

Enhancing Stress Management Coping Skills Using Induced Affect and Collaborative Daily Assessment.

The purpose of this paper is to highlight the use of induced affect (IA) and collaborative (therapeutic) assessment (CA) as components of Cognitive-Affective Stress Management Training (CASMT). IA is a technique for rehearsing cognitive and physical relaxationcoping skills under conditions of high affective arousal, which has been shown to result in high levels of coping self-efficacy. CA provides diary-based feedback to clients about the processes underlying theirstress experiences and helps identify affect-arousing experiences to be targeted by IA. We include descriptions of the IA technique and anonline stress and coping daily diary, as well as sample transcripts illustrating how CA is integrated into CASMT and how IA evokes high affective arousal and skills rehearsal. To illustrate idiographic assessment, we also describe threetreatment cases involving female clients between the ages of 20 and 35 with anxiety symptoms who participated in six weeks of CASMT and reported their daily stress and coping experiences (before, during, and following the intervention)for a total of ten weeks. The resulting time series data, analyzed using Simulation Modeling Analysis (SMA), revealed that all clients reported improved negative affect regulation over the course of treatment, yet they exhibited idiographic patterns of change on other outcome and coping skills variables. These results illustrate how IA and CA may be used to enhance emotional self-regulation and how time-series analyses can identify idiographic aspects of treatment response that would not be evident in group data.

Relation of platelet C4d with all-cause mortality and ischemic stroke in patients with systemic lupus erythematosus.

Systemic lupus erythematosus (SLE) is an autoimmune disease associated with significant morbidity, including premature cardiovascular disease, and mortality. Platelets bearing complement protein C4d (P-C4d) were initially determined to be specific for diagnosis of SLE and were later found to be associated with acute ischemic stroke in non-SLE patients. P-C4d may identify a subset of SLE patients with a worse clinical prognosis. This study investigated the associations of P-C4d with all-cause mortality and vascular events in a lupus cohort. A cohort of 356 consecutive patients with SLE was followed from 2001 to 2009. Primary outcome was all-cause mortality. Secondary outcomes were vascular events (myocardial infarction, coronary artery bypass graft, percutaneous coronary transluminal angioplasty, ischemic stroke, venous thromboembolism, pulmonary embolism, or other thrombosis). P-C4d was measured at study baseline. Seventy SLE patients (19.7%) had P-C4d. Mean follow-up was 4.7 years. All-cause mortality was 4%. P-C4d was associated with all-cause mortality (hazard ratio 7.52, 95% confidence interval (CI) 2.14-26.45, p = 0.002) after adjusting for age, ethnicity, sex, cancer, and anticoagulant use. Vascular event rate was 21.6%. Patients with positive P-C4d were more likely to have had vascular events compared to those with negative P-C4d (35.7 vs. 18.2%, p = 0.001). Specifically, P-C4d was associated with ischemic stroke (odds ratio 4.54, 95% CI 1.63-12.69, p = 0.004) after adjusting for age, ethnicity, and antiphospholipid antibodies. Platelet-C4d is associated with all-cause mortality and stroke in SLE patients. P-C4d may be a prognostic biomarker as well as a pathogenic clue that links platelets, complement activation, and thrombosis.

The development and validation of the Incivility from Customers Scale.

Scant research has examined customers as sources of workplace incivility, despite evidence suggesting that mistreatment is more common from organizational outsiders, including customers, than from organizational members (Grandey, Kern, & Frone, 2007; Schat & Kelloway, 2005). As an important step in extending the literature on customer incivility, we conducted two studies to develop and validate a measure of this construct. Study 1 used focus groups of retail and restaurant employees (n = 30) to elicit a list of uncivil customer behaviors, based on which we wrote initial scale items. Study 2 used a correlational survey design (n = 439) to pare down the number of scale items to 10 and to garner reliability and validity evidence for the scale. Exploratory and confirmatory factor analyses show that the scale is unidimensional and distinguishable from measures of the related, but distinct, constructs of interpersonal justice and psychological aggression from customers. Reliability analyses show that the scale is internally consistent. Significant correlations between the scale and individuals' job satisfaction, turnover intentions, and general and job-specific psychological strain provide evidence of criterion-related validity. Hierarchical regression analyses show that the scale significantly predicts three of four organizational and personal strain outcomes over and above a workplace incivility measure adapted for customer incivility, providing some evidence of incremental validity. Limitations and future research directions are discussed.

Dimensionality of brain networks linked to life-long individual differences in self-control.

The ability to delay gratification in childhood has been linked to positive outcomes in adolescence and adulthood. Here we examine a subsample of participants from a seminal longitudinal study of self-control throughout a subject's life span. Self-control, first studied in children at age 4 years, is now re-examined 40 years later, on a task that required control over the contents of working memory. We examine whether patterns of brain activation on this task can reliably distinguish participants with consistently low and high self-control abilities (low versus high delayers). We find that low delayers recruit significantly higher-dimensional neural networks when performing the task compared with high delayers. High delayers are also more homogeneous as a group in their neural patterns compared with low delayers. From these brain patterns, we can predict with 71% accuracy, whether a participant is a high or low delayer. The present results suggest that dimensionality of neural networks is a biological predictor of self-control abilities.

Preschoolers' delay of gratification predicts their body mass 30 years later.

OBJECTIVE: To assess whether preschoolers' performance on a delay of gratification task would predict their body mass index (BMI) 30 years later. STUDY DESIGN: In the late 1960s/early 1970s, 4-year-olds from a university-affiliated preschool completed the classic delay of gratification task. As part of a longitudinal study, a subset (n = 164; 57% women) were followed up approximately 30 years later and self-reported their height and weight. Data were analyzed using hierarchical regression. RESULTS: Performance on the delay of gratification task accounted for a significant portion of variance in BMI (4%; P < .01), over and above the variance accounted for by sex alone (13%). Each additional minute that a preschooler delayed gratification predicted a 0.2-point reduction in BMI in adulthood. CONCLUSION: Longer delay of gratification at age 4 years was associated with a lower BMI 3 decades later. Because this study is correlational, it is not possible to make causal inferences regarding the relationship between delay duration and BMI. Identifying children with greater difficulty in delaying gratification could help detect children at risk of becoming overweight or obese. Interventions that improve self-control in young children have been developed and might reduce children's risk of becoming overweight and also have positive effects on other outcomes important to society.

Cognitive-affective processing system analysis of intra-individual dynamics in collaborative therapeutic assessment: translating basic theory and research into clinical applications.

According to the cognitive-affective processing system (CAPS) model, behavior is a function of how the distinctive cognitive-affective system of the individual responds to one's subjective experience of the situation encountered. Thus an individual's maladaptive coping processes may be understood by identifying the nature of the situations that a client experiences as highly stressful and the psychological reactions they trigger. An initial study established the feasibility and utility of an Internet-based CAPS daily diary program; it was then used to facilitate a clinical stress-management intervention. The daily diary enabled researchers and clinicians to gather Highly-Repeated Within-Persons (HRWP) data on the situational features, cognitions, affect, and coping behaviors associated with daily life stress, which were then analyzed separately for each participant to identify each individual's unique and distinctive pattern of intra-individual dynamics. Results suggested that individuals differed reliably in the features of psychological situations that triggered stress and maladaptive coping behaviors. HRWP analysis of daily diary data enhanced the efficacy of clinical intervention, and clients' self-regulatory capabilities and life satisfaction were shown to increase over the course of the intervention. We discuss how our program of research fits into the larger goals of translational science and current NIMH clinical research priorities.

Behavioral and neural correlates of delay of gratification 40 years later.

We examined the neural basis of self-regulation in individuals from a cohort of preschoolers who performed the delay-of-gratification task 4 decades ago. Nearly 60 individuals, now in their mid-forties, were tested on "hot" and "cool" versions of a go/nogo task to assess whether delay of gratification in childhood predicts impulse control abilities and sensitivity to alluring cues (happy faces). Individuals who were less able to delay gratification in preschool and consistently showed low self-control abilities in their twenties and thirties performed more poorly than did high delayers when having to suppress a response to a happy face but not to a neutral or fearful face. This finding suggests that sensitivity to environmental hot cues plays a significant role in individuals' ability to suppress actions toward such stimuli. A subset of these participants (n = 26) underwent functional imaging for the first time to test for biased recruitment of frontostriatal circuitry when required to suppress responses to alluring cues. Whereas the prefrontal cortex differentiated between nogo and go trials to a greater extent in high delayers, the ventral striatum showed exaggerated recruitment in low delayers. Thus, resistance to temptation as measured originally by the delay-of-gratification task is a relatively stable individual difference that predicts reliable biases in frontostriatal circuitries that integrate motivational and control processes.

'Willpower' over the life span: decomposing self-regulation.

In the 1960s, Mischel and colleagues developed a simple 'marshmallow test' to measure preschoolers' ability to delay gratification. In numerous follow-up studies over 40 years, this 'test' proved to have surprisingly significant predictive validity for consequential social, cognitive and mental health outcomes over the life course. In this article, we review key findings from the longitudinal work and from earlier delay-of-gratification experiments examining the cognitive appraisal and attention control strategies that underlie this ability. Further, we outline a set of hypotheses that emerge from the intersection of these findings with research on 'cognitive control' mechanisms and their neural bases. We discuss implications of these hypotheses for decomposing the phenomena of 'willpower' and the lifelong individual differences in self-regulatory ability that were identified in the earlier research and that are currently being pursued.

Internet-Based Approaches to Collaborative Therapeutic Assessment: New Opportunities for Professional Psychologists.

Collaborative (or therapeutic) assessment is an empirically supported procedure that involves the client as an active participant in the assessment process. Clients discuss data they provide with the assessor in a collaborative manner designed to provide insights and assist in setting mutually agreeable treatment goals. Internet-based procedures allow for ongoing (including daily) tracking of psychological variables and provision of immediate graphic feedback to therapists, clients, and clinical supervisors. As an example, we describe one such system: Evidence-Based Assessment System for Clinicians (EAS-C) that contains more than 30 brief and empirically validated assessment instruments that can be completed via the internet or smartphone. We also provide examples from a stress management intervention demonstrating how single-client data from a web-based daily stress and coping diary tied to the EAS-C were utilized to provide clients with individualized feedback, assess progress, identify idiographic patterns of cognitions, affect, and coping strategies, and test clinical hypotheses. Internet- and computer-based technological advances can improve service delivery and help bridge the gap that currently exists between science and practice.

Glycoproteomics of milk: differences in sugar epitopes on human and bovine milk fat globule membranes.

Oligosaccharides from human and bovine milk fat globule membranes were analyzed by LC-MS and LC-MS/MS. Global release of N-linked and O-linked oligosaccharides showed both to be highly sialylated, with bovine peak-lactating milk O-linked oligosaccharides presenting as mono- and disialylated core 1 oligosaccharides (Galbeta1-3GalNAcol), while human milk had core type 2 oligosaccharides (Galbeta1-3(GlcNAcbeta1-6)GalNAcol) with sialylation on the C-3 branch. The C-6 branch of these structures was extended with branched and unbranched N-acetyllactosamine units terminating in blood group H and Lewis type epitopes. These epitopes were also presented on the reducing terminus of the human, but not the bovine, N-linked oligosaccharides. The O-linked structures were found to be attached to the high molecular mass mucins isolated by agarose-polyacrylamide composite gel electrophoresis, where MUC1 and MUC4 were present. Analysis of bovine colostrum showed that O-linked core 2 oligosaccharides are present at the early stage (3 days after birth) but are down-regulated as lactation develops. This data indicates that human milk may provide different innate immune protection against pathogens compared to bovine milk, as evidenced by the presence of Lewis b epitope, a target for the Helicobacter pylori bacteria, on human, but not bovine, milk fat globule membrane mucins. In addition, non-mucin-type O-linked fucosylated oligosaccharides were found (NeuAc-Gal-GlcNAc1-3Fuc-ol in bovine milk and Gal-GlcNAc1-3Fuc-ol in human milk). The O-linked fucose structure in human milk is the first to our knowledge to be found on high molecular mass mucin-type molecules.

Real and imagined body movement primes metaphor comprehension.

We demonstrate in two experiments that real and imagined body movements appropriate to metaphorical phrases facilitate people's immediate comprehension of these phrases. Participants first learned to make different body movements given specific cues. In two reading time studies, people were faster to understand a metaphorical phrase, such as push the argument, when they had previously just made an appropriate body action (e.g., a push movement) (Experiment 1), or imagined making a specific body movement (Experiment 2), than when they first made a mismatching body action (e.g., a chewing movement) or no movement. These findings support the idea that appropriate body action, or even imagined action, enhances people's embodied, metaphorical construal of abstract concepts that are referred to in metaphorical phrases.

Evaluation of a voluntary, military-style residential treatment program for adolescents with academic and conduct problems.

This study evaluated the effectiveness of a military-style residential treatment program for adolescents with academic and conduct problems. Two hundred twelve referred adolescents were separated into 3 groups for analyses: (a) adolescents who completed the 22-week program, (b) adolescents who prematurely withdrew, and (c) wait-list controls. Adolescents' socioemotional and behavioral functioning were measured at baseline and 6 months after treatment. Results showed statistically and clinically significant reductions in externalizing symptoms and increases in adaptive behavior associated with treatment. Treatment was also associated with increased likelihood of high school completion or employment and decreased likelihood of alcohol or drug problems and arrest. The relation between treatment participation and outcomes was moderated by adolescents' living environments after treatment, but it was not moderated by age of symptom onset. The benefits of treatment may be partially attributable to the voluntary nature of the intervention.

Population pharmacokinetics as a method to detect variable risperidone exposure in patients suffering from dementia with behavioral disturbances.

OBJECTIVE: This study was intended to compare the consistency of risperidone exposure in patients who have dementia and behavioral disturbances treated in a psychiatric hospital versus a community care setting. METHODS: Population pharmacokinetic modeling was used to assess the consistency of risperidone exposure in Alzheimer's disease patients with agitation. The ratio of predicted to observed drug concentrations (Cpred/Cobs) derived from this model was used to compare exposure in the inpatient versus long-term/home care settings using both the mean and the variance of this term across groups. RESULTS: The modeled Cpred/Cobs ratios had a much higher within-subject variance in the inpatients than in the community care patients (117.03% vs 72.35%; P < 0.001). The central tendencies of the Cpred/Cobs ratios across the 2 groups were not significantly different. CONCLUSIONS: Exposure to risperidone was more variable in a psychiatric hospital than in a community care setting. Future research may help to identify the specific contributors to the increased variance observed in this pilot study.

Tai Chi and fall reductions in older adults: a randomized controlled trial.

BACKGROUND: The authors' objective was to evaluate the efficacy of a 6-month Tai Chi intervention for decreasing the number of falls and the risk for falling in older persons. METHODS: This randomized controlled trial involved a sample of 256 physically inactive, community-dwelling adults aged 70 to 92 (mean age, 77.48 years; standard deviation, 4.95 years) who were recruited through a patient database in Portland, Oregon. Participants were randomized to participate in a three-times-per-week Tai Chi group or to a stretching control group for 6 months. The primary outcome measure was the number of falls; the secondary outcome measures included functional balance (Berg Balance Scale, Dynamic Gait Index, Functional Reach, and single-leg standing), physical performance (50-foot speed walk, Up&Go), and fear of falling, assessed at baseline, 3 months, 6 months (intervention termination), and at a 6-month postintervention follow-up. RESULTS: At the end of the 6-month intervention, significantly fewer falls (n=38 vs 73; p=.007), lower proportions of fallers (28% vs 46%; p=.01), and fewer injurious falls (7% vs 18%; p=.03) were observed in the Tai Chi group compared with the stretching control group. After adjusting for baseline covariates, the risk for multiple falls in the Tai Chi group was 55% lower than that of the stretching control group (risk ratio,.45; 95% confidence interval, 0.30 to 0.70). Compared with the stretching control participants, the Tai Chi participants showed significant improvements (p<.001) in all measures of functional balance, physical performance, and reduced fear of falling. Intervention gains in these measures were maintained at a 6-month postintervention follow-up in the Tai Chi group. CONCLUSIONS: A three-times-per-week, 6-month Tai Chi program is effective in decreasing the number of falls, the risk for falling, and the fear of falling, and it improves functional balance and physical performance in physically inactive persons aged 70 years or older.

Negative ion graphitised carbon nano-liquid chromatography/mass spectrometry increases sensitivity for glycoprotein oligosaccharide analysis.

Negative ion nano-liquid chromatography/mass spectrometry (nano-LC/MS) and tandem mass spectrometry (nano-LC/MS(2)), using graphitised carbon as separating medium, were explored for analysing neutral and acidic O-linked and N-linked oligosaccharide alditols. Compared to the sensitivity of capillary LC/MS (flow rate of 6 microL/min) coupled with a conventional electrospray ionisation source, the nano-LC/MS (flow rate of 0.6 microL/min) with a nanoflow ion source was shown to increase the sensitivity ten-fold with a detection limit in the low-femtomole range. The absolute signals for the [M-nH](n-) ions of the oligosaccharides were increased 100-fold, enabling accumulation of high-quality fragmentation data in MS(2) mode, in which detection of low abundant sequence ions is necessary for characterisation of highly sialylated N-linked oligosaccharides. Oligosaccharides with high numbers of sialic acid residues gave dominant fragments arising from the loss of sialic acid, and less abundant fragments from cleavage of other glycosidic bonds. Enzymatic off-line desialylation of oligosaccharides in the low-femtomole range prior to MS(2) analysis was shown to increase the quality of the spectra. Automated glycofragment mass fingerprinting using the GlycosidIQ software confirmed the oligosaccharide sequence for both neutral desialylated as well as sialylated structures. Furthermore, the use of graphitised carbon nano-LC/MS enabled the detection of four sialylated O-linked oligosaccharides on membrane proteins from ovarian tissue (5 microg of total amount of protein).

Fear of falling in elderly persons: association with falls, functional ability, and quality of life.

This study examined heterogeneity in response patterns of the participants of the Survey of Activities and Fear of Falling in the Elderly (SAFFE) and their relationships to falls, functional ability, quality of life, and activity restriction measures in a cohort of 256 older people (mean age = 77.5 years). Participants recruited from local primary care clinics were administered the SAFFE instrument, an activity restriction measure, a combination of self-reported and performance-based functional ability tests, and quality-of-life measures. Latent class analyses identified two classes: Class 1 (n = 209), which had a low SAFFE fear of falling, and Class 2 (n = 47), which had a high SAFFE fear of falling. Subsequent analyses of variance indicated that the two-class (low fear and high fear) SAFFE fear of falling profiles discriminated fallers from nonfallers, and low and high levels of functional ability, activity restriction, and quality of life. The findings from this study suggest that variations in the SAFFE response patterns on a single dimension of fear of falling and that high levels of fear of falling measured by the SAFFE are linked to a range of adverse health consequences.

Self-efficacy as a mediator between fear of falling and functional ability in the elderly.

OBJECTIVES: This study examined falls self-efficacy and fear of falling to determine whether self-efficacy acts as a mediator between fear of falling and functional ability. METHODS: Using the Survey of Activities and Fear of Falling in the Elderly as a fear-of-falling measure and the Activities-Specific Balance Confidence Scale for falls self-efficacy, structural relationships among fear of falling, self-efficacy, functional balance, and physical functioning outcomes were tested with older adults (N = 256, M age = 77.5). RESULTS: Lower levels of fear of falling were significantly related to higher levels of falls self-efficacy, which was in turn associated with better functional outcomes. Moreover, falls self-efficacy mediated the effects of fear of falling on functional outcomes. DISCUSSION: Results substantiate the hypothesized mediational role of falls self-efficacy in fear of falling and underscore the need to consider ways of enhancing falls self-efficacy in interventions aimed at reducing falls and fear of falling.
