Testing a Model of Mammography Intention1

This paper presents the results of a study testing components of the Triandis model of choice to predict intention to obtain screening mammography in the next 2 years. A questionnaire was developed to measure the theoretical components of this model. Analysis was based on 2,521 women, 50 to 65 years old, who received primary care from 1 of 28 participating primary care group practices. Based on the four theoretical components of intention described in the Triandis model-social influence, affect, consequence, and barriers-a set of structural equation models was explored. The sample was split into two equal subsamples: one sample used for model exploration and one used for model confirmation. Results showed that the original intention model was not supported. Instead, the model that best fit the data, and upheld it in the subsample used for model confirmation, was a model in which habit and intention were strongly related. The strongest predictors of habit were barriers and consequences; the strongest predictors of intention were social influences and barriers.     

A ToolBook computer program to develop course objectives and assessment measures

College courses are generally developed because of current fashion in the field and/or student and faculty interest in some topic without reference to departmental or programmatic goals. Current calls and needs for accountability in higher education demand a more organized approach. A computer program, ToolBook 1.53, which provides information to the instructor about systematic development of courses and assessment of student outcomes, is described. The program supports the construction of outcome-oriented learning objectives and corresponding assessment techniques. Instructors who used this program to learn about how to construct such objectives showed an increase in knowledge and evaluated the program positively. Using the information provided in this program leads to an integrated approach to course design and development in which course objectives are linked to the college mission statement through departmental or program objectives.     

Use of behavioral techniques by paraprofessional staff: A review and proposal

Paraprofessionals are increasingly being employed to provide direct care to children and adults who have behavioral deficits and excesses, such as those labeled developmentally disabled, mentally ill, or delinquent. Behavioral techniques, if effectively taught to paraprofessionals, offer ways of both teaching new skills to clients and reducing their undesirable behaviors. This article describes the methods that have been used to teach paraprofessionals to use behavioral techniques, how these skills can be maintained on the job, and the effects upon client behavior that result from this teaching of paraprofessionals. In addition, a system for teaching staff to implement and continue to use behavioral techniques is proposed.     

Syntactic and semantic contributions to sentence comprehension in agrammatism

Five aphasic subjects, who demonstrated agrammatic speech, and eight control subjects were presented with a sentence-picture matching task in which the factors of syntactic complexity, semantic reversibility, and sentence plausibility were independently varied. A subset of the sentences was patterned after that presented by A. Caramazza and E. Zurif (1976, Brain and Language, 5, 572-583) who concluded that Broca's aphasics rely on semantic constraints instead of syntactic information for sentence comprehension. Our aphasic subjects showed the same pattern of performance on this subset of sentences. However, the results from the full set of sentence materials we tested show that the aphasic subjects could perform some sentence level syntactic analyses, even when syntactic information conflicted with semantic constraints. The aphasic subjects correctly interpreted most active and passive sentences. They failed, however, to assign thematic roles and adjectives in center-embedded relative sentences, and instead relied on nonsyntactic information. These results show that both semantic and syntactic information contributed to sentence comprehension in the aphasic subjects we tested, in contrast to previous claims that syntactic and semantic processes are completely dissociated in this population.     

Effects of color stimulation and information on the copying performance of attention-problem adolescents

The optimal stimulation theory proposes that hyperactive children are less tolerant of lower levels of arousal than nonhyperactive children and should thus derive greater gains from stimulation added to repetitive copying tasks than do comparisons. To test this hypothesis, 16 adolescents, rating high on attention and behavior problems, were matched on the basis of age and poor handwriting performance to 16 controls. Matched pairs were randomly assigned to treatment order (high-stimulation colored letters followed in 2 weeks by low-stimulation black letters or the reverse order) and to level of information (color added to difficult letter parts or added to randomly selected letters), counterbalanced for treatment order and level of information within each order. Errors and activity were subjected to a mixed-design analysis of covariance, with IQ the covariate. The major findings indicated that attention-problem adolescents performed better with high-stimulation task stimuli than with low, relative to the opposite performance pattern of controls. Different responding was significant for experimental but not for control children.This research was supported by National Institute of Mental Health Grant MH32282 to the first author.     

Self-esteem and beliefs about memory in environmentally stable and relocated students

This research examined beliefs about the utility of environmental, semantic, and phonological cues for remembering, as these beliefs are related to feelings of self-esteem, assertiveness, and locus of control. We proposed different types of relationships between self-esteem (and assertiveness) and metamemory for two group of college students, based on their differential experiences with distinctive memory failures. For students who were familiar with their current environment, self-esteem was positively related to confidence in having a good memory. It was only for newcomers—students who had recently moved to a new environment—that beliefs about the benefits of environmental cues were positively related to self-esteem and assertiveness. These results suggested that if newcomers were less aware of the utility of environmental cues, they were more likely to attribute their memory failures to their own inadequacies. We also obtained evidence that subjects with an internal locus of control were more knowledgeable regarding the utility of environmental cues than were externally oriented subjects.     

Using the common-sense model to predict risk perception and disease-related worry in individuals at increased risk for venous thrombosis.

OBJECTIVE: This study applied the Common-Sense Model (CSM) to predict risk perception and disease-related worry in 174 individuals with a genetic predisposition to venous thrombosis (thrombophilia). DESIGN: Participants completed an adapted version of the Illness Perception Questionnaire-Revised (IPQ-R) and measures assessing risk perception and worry. RESULTS: Regression analyses revealed that illness perceptions were predictors of risk perception and thrombosis worry. The hypothesis that illness perceptions mediate the relationship between a person's experience of venous thrombosis and perceived risk and thrombosis worry could not be confirmed. CONCLUSIONS: Further research should refine the IPQ-R for populations at risk of a disease and examine the value of the CSM in explaining the relationship between risk perception, worry, and health behavior.
