Eliciting salient beliefs in research on the theory of planned behaviour: The effect of question wording

The authors of the theory of reasoned action (TRA) and its extension, the theory of planned behaviour (TPB) recommend that researchers who use these theories to investigate the determinants of a given behaviour should first conduct an elicitation study to identify the modal salient beliefs in the target population. In spite of the importance accorded to salient beliefs by the TRA/TPB, the elicitation stage has received little research attention. This paper reports a detailed analysis of beliefs about “being more physically active in the next 12 months.” A general population sample of 213 adults completed a questionnaire while attending a research centre for a series of tests. The findings showed that the beliefs that were elicited by questions designed to prompt affective outcomes (like or enjoy, dislike or hate) differed systematically from those that were elicited by the traditional questions designed to prompt instrumental out-comes (advantages and disadvantages). Whether this resulted in different final sets of modal salient beliefs was found to depend on the particular decision rule that was employed. An alternative decision rule is proposed, based on maximizing the degree of overlap between the modal set and the full set of salient beliefs generated by the sample. The index of overlap can be used to gauge the adequacy of using a modal set of a given size to represent the salient beliefs of the whole sample. In the current dataset, the optimal modal set for “advantages and disadvantages” was associated with only 26 percent overlap with the salient beliefs of the whole sample, which was judged to be insufficient. In such cases, a better strategy may be to ask participants to generate and rate their own beliefs.     

Internet use and social support in women with breast cancer.

Many Web sites offer information to breast cancer patients, who are increasingly using these sites. The authors investigated the potential psychological benefits of Internet use for medical information by breast cancer patients. Of the 251 women approached, 188 were successfully interviewed (74.9%). Forty-two percent used the Internet for medical information related to breast health issues and did so for an average of 0.80 hr per week. The Interpersonal Support Evaluation List and the UCLA Loneliness Scale, with results controlled for covariates, showed that Internet use for breast health issues was associated with greater social support and less loneliness than Internet use for other purposes or nonuse. Breast cancer patients may obtain these psychological benefits with only a minimal weekly time commitment.     

Retroactive interference in rats: Independent effects of time and similarity of the intervening event with respect to acquisition

Events occurring during the retention intervals for a 5-min delayed alternation task were used to investigate the factors that influence retroactive interference. Appetitive reinforcement in an E-maze was employed to train rats on the delayed alternation task consisting of a forced-choice (target event) trial followed by a free-choice (test) trial. Occasional probe trials added a potentially interfering event either at the beginning, middle, or end of the retention period. These events also varied in similarity to the target events, ranging from low similarity to the converse of the target event. Interference increased both with the interval between the target and intervening events and with the similarity between the converse of the target event and the intervening event; however, there was no tendency, significant or otherwise, towards an interaction between stimulus similarity and the interval between the target and intervening events. Control groups demonstrated that the interference was of an associative nature and that the interval between the intervening event and the test trial was little consequence. These results are discussed in terms of two separate types of interference: similarity interference which depends on stimulus similarity of the intervening event to the converse of the target event but not on the temporal location of the intervening event, and processing interference which depends on the temporal location of the intervening event but not on its similarity to the converse of the target event.     

Thoughts of Death and Suicide in Early Adolescence

The prevalence and persistence of thoughts of death and suicide during early adolescence were estimated in a community‐based cohort. A latent class approach was used to identify distinct subgroups based on endorsements to depression items administered repeatedly over 24 months. Two classes emerged, with 75% in a low ideation class across four assessments. Less than 2% persisted in the high ideation class over three or more assessments. African American and Asian American adolescents were more likely than European Americans to belong to the high ideation class. No members of the low ideation class endorsed “thought about killing myself,” while “thoughts of death and dying” was endorsed by members of both classes. Implications for interpreting meanings of death and suicide ideation in early adolescence are discussed.     

Children's Narratives Following Traumatic Brain Injury: Linguistic Structure, Cohesion, and Thematic Recall

Narrative discourse and intellectual functioning were examined 3 years following traumatic brain injury (TBI) in children 1 to 8 years of age at the time of injury. The language-impaired TBI group (n= 9) had language deficits during the subacute stage of recovery; their performance was contrasted with that of a TBI comparison group equated on neurologic and demographic variables that did not show subacute language impairment (n= 8) and a sibling comparison group (n= 9). The language-impaired TBI group had lower Verbal and Full-Scale IQ scores and produced fewer words and utterances than the sibling group on a story retelling task; their stories were characterized by fewer complete referential and lexical ties and more referential errors, indicating difficulty conjoining meaning across sentences. The language-impaired TBI group recalled approximately one-third of the propositions needed to maintain the story theme and made more errors sequencing the propositions than either the TBI or the sibling comparison groups. Group differences were not obtained on the Performance IQ scores or on measures of rate or fluency of speech production, mazes, use of conjunctives, or naming errors. The discourse deficiencies of children with TBI and acute language impairment were most pronounced at the level of cognitive organization of the text reflecting text macrostructure and were least apparent at the level of lexical and sentential organization reflecting text microstructure. Results are discussed in terms of the vulnerability of developing language abilities to disruption by brain injury.     

Representativeness reasoning and the search for the origins of stuttering: A return to basic observations

In this paper, we present our views on theories of the distal and proximal causes of stuttering. We suggest that the search for the etiology of stuttering has been hampered by the inappropriate use of the representativeness heuristic, a method of reasoning which proposes that the effects of a disorder reflect its causes. We encourage a return to the ideas of Froeschels and Bluemel so that the representativeness heuristic might properly be employed in investigations into the proximal, mechanical causes of stuttering and into the etiological implications of the repetitions of early stuttering.     

Impacting Awareness of Child Abuse through a Performing Arts Project

A folk opera, AVE, explored issues of child abuse, sexual assault and violence through the character of Mary Magdelene. Using indigenous religious folklore images, Magdelene is befriended by Jesus's mother and healed of her childhood wound through a religious conversion. Six hundred secondary students attended three daytime performances and 486 returned a Likert‐scaled questionnaire. Results indicated most students perceived abuse as a personally relevant, real social problem, with felt relevance increasing with age. Significant trends supported initial expectations with an increase in community and personal awareness of child abuse/sexual assault and an increase in personal and community interest in helping others. Community risk factors contributing to denial of abuse were explored. More Hispanics responded positively to the sense of benefit. Findings suggest that performing arts can help increase awareness of child abuse as well as help stimulate personal and community interest in helping. This benefit increases with teacher discussion and age.
