Correspondence between statistically derived behavior problem syndromes and child psychiatric diagnoses in a community sample

The correspondence between Diagnostic and Statistical Manual (3rd ed.) (DSM-III) diagnoses and statistically derived syndromes was examined within a community sample of children and adolescents in Puerto Rico. Specifically, the extent to which behavior dimensions, derived from the Child Behavior Checklist and the Youth Self-Report, corresponded to psychiatric diagnoses, derived from parent and child versions of the Diagnostic Interview Schedule for Children, was examined. The alternative approaches for assessing psychopathology in children and adolescents were compared against external validators. The results indicated a meaningful convergence between DSM-III diagnoses and statistical syndromes; however, a one-to-one correspondence did not emerge. Little evidence was found for diagnostic thresholds. There was no evidence of the superiority of either the statistically derived syndromes or the DSM-III diagnoses. The incorporation of a measure of impairment improved the validity of both approaches. Adding parental reports to the selfreports of adolescents yielded little gain in the validity of either the statistical or diagnostic approach. The implications for the definition and assessment of child and adolescent disorders are discussed.This research was supported by grant MH 38821 from the National Institute of Mental Health.The authors wish to acknowledge Glorisa Canino, Ph.D., and Maritza Rubio-Stipec, M.A., of the University of Puerto Rico, co-investigators in the epidemiologic project and to Barbara Bettes, Ph.D. for her contribution to preliminary analyses for this manuscripl.

Salesperson ambidexterity and customer satisfaction: examining the role of customer demandingness,adaptive selling,and role conflict

This research investigates the effects of sales-service ambidexterity on salesperson role perceptions, behaviors, and customer satisfaction. Using a business-to-business, salesperson-customer sample, we build and test a model which highlights both the positive and negative consequences of this simultaneous goal pursuit. Specifically, while sales-service ambidexterity positively impacts adaptive selling behaviors, it also increases perceptions of role conflict among salespeople. Customer demandingness moderates these relationships. Taken together, the results provide insights for firms on how to manage their sales force to optimize both sales and service outcomes based on characteristics of their salespeople and customers.     

Coping with asymmetry: How infants and adults walk with one elongated leg

The stability of a system affects how it will handle a perturbation: The system may compensate for the perturbation or not. This study examined how 14-month-old infants—notoriously unstable walkers—and adults cope with a perturbation to walking. We attached a platform to one of participants’ shoes, forcing them to walk with one elongated leg. At first, the platform shoe caused both age groups to slow down and limp, and caused infants to misstep and fall. But after a few trials, infants altered their gait to compensate for the platform shoe whereas adults did not; infants recovered symmetrical gait whereas adults continued to limp. Apparently, adult walking was stable enough to cope with the perturbation, but infants risked falling if they did not compensate. Compensation depends on the interplay of multiple factors: The availability of a compensatory response, the cost of compensation, and the stability of the system being perturbed.     

The double-edged effects of emotional intelligence on the adaptive selling–salesperson-owned loyalty relationship

Emotional intelligence can positively impact sales outcomes. However, research is needed to enhance our understanding about how salesperson's emotional intelligence affects adaptive selling and customer outcomes. This study uses dyadic data from 150 customers matched with 25 salespeople to investigate relationships among emotional intelligence, adaptive selling (AS) and customer loyalty perceptions. Research findings show that regulation of emotions negatively affects salesperson-owned loyalty (SOL), while it positively moderates the AS-SOL relationship. These findings are critical as they challenge the pervasive conception of the positive impact of regulation of emotions in sales. Results also provide further evidence that SOL is important to the firm as it positively affects loyalty to the service provider and through mediating processes also impacts word of mouth.
