The Effects of Source Credibility and Performance Rating Discrepancy on Reactions to Multiple Raters1

Using multiple feedback sources, the present study investigated the effects of source credibility and performance rating discrepancy on recipients' reactions. Individuals performed an ambiguous group task, rated their own performance on the task, and were later provided bogus feedback ostensibly from their peers and an expert rater. Individuals reacted toward the feedback and the source of the feedback as a function of the rating discrepancy and credibility of the feedback source. Generally, more credible sources and their feedback were evaluated more favorably. However, as predicted, this effect was overcome by performance rating discrepancy in the predicted conditions. The results show the importance of studying the interactive effects of message and source characteristics on individuals' reactions.     

A multisystems analysis of adolescent suicide attempters

The present study tested an ecologically based model, which predicted that hopelessness (individual level) mediates the effects of family dysfunction (interpersonal level) and socioeconomic status (sociocultural level) on both suicidal intent and suicidal ideation, within a sample of attempters. Subjects included adolescent males and females presenting at a general hospital emergency room following suicide attempts. Baron and Kenny's (1986) criteria for testing mediation models through multiple-regression analyses were employed. Little evidence of mediation was found. Hopelessness proved to be the best predictor of suicidal intent and ideation within a sample of attempters.     

Developmental and Adjustment Issues of Gay, Lesbian, and Bisexual Adolescents: A Review of the Empirical Literature

Various studies have reported adjustment problems experienced by gay, lesbian, and bisexual (GLB) adolescents. A primary purpose of this paper is to critically review this literature. Difficulties that have been studied include past suicide attempts, substance use and abuse, conduct problems, and academic concerns. For example, a considerable number of GLB youth report a history of suicide attempts, with prevalence rates ranging from 11 to 42%. However, among other methodological concerns, studies in this area have not used a comparison sample of heterosexual youths. Characteristics of development particular to GLB adolescents are described, the empirical research on adjustment issues is reviewed, and potential risk and protective factors for GLB youths are discussed.     

Detection of gender-related categories by 10-month-old infants

Thirty-two 10-month-olds completed an habituation procedure where a male or female face was paired with a specific object. Results reveal 10-month-olds can form categories based on correlations among attributes of social information. Basic processes involved in gender role formation are present in 10-month-olds.     

Thresholds for conditioned suppression using X-rays as the pre-aversive stimulus

Four male, 12-week-old Sprague-Dawley rats were used to determine the threshold for behavioral response to X-irradiation using the conditioned suppression technique. They were maintained at 80 per cent body weight and initially trained to stable performance on a VI 1 min schedule with 16 per cent sucrose solution as reinforcement. After a stable baseline was obtained, animals were placed in the instrumental conditioning box beneath the X-ray machine for a half-hour session each day. While subjects were actively pressing the lever for reinforcement, 15-sec X-ray exposures of 0.5 R/sec were administered, followed immediately by electric shock. After all animals had exhibited conditioned suppression, the dose-rate was decreased in subsequent sessions in an effort to establish threshold. The results indicate that X-rays at a dose-rate as low as 0.004 R/sec can be an effective pre-aversive stimulus for the rat.     

Evaluating skills correlated with discriminated responding in multiple schedule arrangements

One potential solution for excessively high‐rate functional communication responses (FCR) is to establish stimulus control of the FCR through a multiple schedule. However, several studies have demonstrated difficulty with establishing discriminated responding across multiple schedule components. The primary aim of the current study was to evaluate how participants’ skills related to color discrimination may be related to the emergence of discriminated responding in a multiple schedule with colors as the schedule‐correlated stimuli. Three secondary aims of the current study were to evaluate: a) varied multiple schedule arrangements, b) if topographically dissimilar stimuli facilitated the emergence of discriminated responding, and c) if employing different colored stimuli across multiple schedule arrangements reduced the likelihood that discriminated responding emerged simultaneously across varied arrangements. Nine participants’ ability to match, select, tact, and respond intraverbally to colors was assessed, and 1 of 2 evaluations of multiple schedule arrangements were conducted. Results indicated that participants’ ability to select and tact colors was strongly correlated with the efficacy of standard multiple schedule arrangements. Additionally, multiple schedule arrangements employing topographically dissimilar stimuli were observed to be equally as effective as standard arrangements and the inclusion of different colored stimuli across arrangements did not reduce the likelihood that discriminated responding emerged simultaneously across all conditions, when it was observed to emerge at all.     

Implementation and Preliminary Feasibility of an Individualized,Supportive Approach to Behavioral Care for Parents of Young Children Newly Diagnosed With Type 1 Diabetes

There are significant stressors related to parenting a young child with newly diagnosed type 1 diabetes (T1D). Despite these challenges, there are not yet clearly defined interventions to help promote psychological health and adherence for families with young children with T1D. First STEPS is a tailored stepped care design intervention to positively impact parents’ emotional functioning and children’s glycemic control in young children newly diagnosed with T1D. The First STEPS intervention is derived from a combination of Cognitive Behavioral Theory and Social Cognitive Theory to support family adjustment to T1D, promote parental mastery over T1D tasks, increase coping skills to manage stressors associated with T1D, and build on the strengths of families newly diagnosed with T1D to help them achieve positive health and wellbeing outcomes. We present details about the intervention and describe two pilot participants as case studies. Results indicated that the treatment and delivery model were acceptable to the pilot participants, as evidenced by treatment completion and satisfaction ratings. Future directions for this work include testing the efficacy of this new treatment in a randomized controlled trial.
