Using Public Service Announcements to Change Behavior: No More Money and Oil Down the Drain1

Radio and television offer promising media for addressing large‐scale social problems. Unfortunately, very few mass‐media messages have utilized social psychological theories of persuasion and influence. This article summarizes 2 studies that evaluated the effectiveness of a state‐sponsored public service announcement aimed at reducing improper disposal of used motor oil among do‐it‐yourself oil changers. Study 1 was a field experiment with 120 oil changers in San Diego County. Inertial resistance and low perceived behavioral control were identified as obstacles to proper disposal. In Study 2 , we used the disrupt‐then‐reframe technique to successfully overcome these obstacles and promote proper disposal of used oil. The results underscore the usefulness of empirically validated persuasion techniques in changing behavior via mass media.     

Evidence of Impaired Glucose Tolerance and Insulin Resistance in Patients With Alzheimer’s Disease

Alzheimer’s disease (AD) and diabetes rarely occur together, a finding that provides a possible clue as to the development of AD. Abnormal glucose metabolism is not limited to diabetes, but also can include impaired glucose tolerance, insulin resistance, and hyperinsulinemia. AD patients have significantly varying insulin levels after drinking sugared sodas and thus may be classified as insulin resistant. After reviewing the literature on impaired glucose tolerance and insulin production in AD, we present several hypotheses as possible explanations for the relationship between insulin resistance and AD. Finally, we suggest future studies, including studies on use of thiazolidinediones (currently used in the treatment of diabetes) in AD.     

Conceptual organization and memory in nonretarded, mildly retarded, and moderately retarded adults

Moderately retarded, mildly retarded, and nonretarded adults learned a list of 12 items from three categories to a criterion of 75% correct recall in a free-recall learning paradigm. Retention was measured 1 week later. The moderately retarded took more trials and had lower retention and clustering scores than the others. The mildly retarded took more trials and had lower retention than the nonretarded. The results violate Murdock's total time hypothesis (Cooper & Pantle, 1967) but support Mandler's (1967) contention that learning is enhanced by the mental capacity for organization.     

Analysis of Kavale and Mattson's "balance beam" study (1983): criteria for selection of articles

The effects of perceptual motor training in children with learning disabilities have been hotly debated for many years. Proponents have included many of the pioneers in the fields of learning disabilities and motor development. Among the challenges perhaps the most sophisticated one has been the meta-analysis by Kavale and Mattson. Their conclusion was that perceptual motor training was not an effective intervention for children with disabilities. The purpose of this project was to analyze critically the Kavale and Mattson meta-analysis from the perspective of an adapted physical educator and to consider the validity of this meta-analysis when examining multiple interventions dealing with a multitude of disabilities. A critical analysis of all 180 studies question their conclusions.     

Observations and ratings of tics in school settings

This paper describes the findings of a school-based tic assessment procedure (direct observations, teacher rating scales) for hyperactive children with comorbid tic disorder. Rates of motor tic frequency were found to be moderately stable across both days and school settings. Correlations between direct observations of tics and clinician rating scales were generally in the low to moderate range as were correlations between teacher and clinician rating scales. Overall rates of hyperactive/disruptive behaviors were not associated with rates of motor tic occurrence, and the behavioral symptoms of both disorders were also independent for specific intervals of time.This study was supported, in part, by a research grant from the Tourette Syndrome Association, Inc., and P.H.S. grant MH 45358 from the National Institute of Mental Health. The authors wish to thank Joyce Sprafkin for providing valuable clinical services related to the conduct of the school-based medication evaluations and Joseph Schwartz for assisting with the data analyses. We are particularly indebted to the families and teachers who made this study possible.     

Correlates of suicidal behaviors among Asian American outpatient youths

Medical record abstraction was conducted at an ethnic-specific mental health outpatient clinic to identify correlates of suicidal behaviors in a sample of 285 Asian American youths. Some risk factors, such as parent-child conflict and age, which have been associated with suicidality in majority group youths, predicted suicidality in this sample, whereas other risk factors, such as gender, did not generalize to this sample. Acculturation interacted with the risk factor of parent-child conflict to predict suicidality. Less acculturated Asian youths were at proportionally greater risk for suicidality under conditions of high parent-child conflict than were their more acculturated counterparts. This finding underscores the importance of culture as a context for determining the relevance of stressors for potentiating psychopathology.
