Predicting the Performance of Dental Hygiene Behaviors: An Examination of the Fishbein and Ajzen Model and Self-Efficacy Expectations1

This study examined the value of the Fishbein and Ajzen model of behavioral intentions and Bandura's concept of self-efficacy expectations as prospective predictors of the dental hygiene behaviors of young adults. All participants (73 males and 58 females) completed self-report measures of the predictor variables and 60% of that group (N = 77) then recorded brushing and flossing behaviors over a four-week period. The Fishbein and Ajzen model accounted for a significant proportion of the variance in intentions to brush (R²= .32) and intentions to floss (R²= .30). Intentions were in turn related to self-monitoring records of brushing and flossing frequency (rs= .52 and .61). Introducing self-efficacy expectations into the Fishbein and Ajzen model failed to improve the prediction of brushing and flossing frequency. However, self-efficacy was predictive of behavioral intentions, adding significantly to the variance accounted for by the attitudinal and subjective norm components of the Fishbein and Ajzen model. These data suggest that self-efficacy expectations are important in understanding protective health behaviors and that the inclusion of a self-efficacy component in the Fishbein and Ajzen model deserves consideration.     

Sex stereotyping of infants: A review of gender labeling studies

Studies that have addressed the question of whether adults and children respond differently to male and female infants because of actual differences in the infants or because of preconceived sex stereotypes are reviewed, and the overall conclusions from these studies are evaluated. Twenty-three studies were identified in which neutrally clothed infant stimuli were labeled male in some conditions and female in other conditions. The strength and consistency of gender labeling effects on perceptions and behaviors in these studies were appraised. The results indicate that knowledge of an infant's gender is not a consistent determinant of adults' reactions, but more strongly influences young children's reactions. The implications of these findings for research on early sex role socialization are considered.     

Can Semantics Guide Ontology?

Since the linguistic turn, many have taken semantics to guide ontology. Here, I argue that semantics can, at best, serve as a partial guide to ontological commitment. If semantics were to be our guide, semantic data and semantic treatments would need to be taken seriously. Through an examination of plurals and their treatments, I argue that there can be multiple, equally semantically adequate, treatments of a natural language theory. Further, such treatments can attribute different ontological commitments to a theory. Given this, I argue that semantics can fail to deliver determinate ontological commitments and determinate answers to ontological questions, more generally.     

The Ethical Inclusion of Children With Psychotic Disorders in Research: Recommendations for an Educative,Multimodal Assent Process

This article addresses the issue of properly assenting children with psychotic disorders to participate in clinical research. Due to the protective concerns with such a vulnerable population, additional precautions are necessary to ensure that youth with psychotic disorders assent to research with an appropriate level of understanding regarding study procedures. Current literature suggests that positive/negative symptoms and minor cognitive deficits do not interfere with the ability to comprehend study-related information for adults with psychosis if the study information is presented through an educative process. Similarly, youth benefit from repeated presentation of procedures and periodic assessment of their comprehension. An integrated educative process is proposed that emphasizes the importance of an interactive consent through repetition and participant/investigator feedback.     

The associations between adult attachment,posttraumatic symptoms,and posttraumatic growth

Background and Objectives: Individual differences after trauma vary considerably and can range from posttraumatic stress disorder (PTSD) to posttraumatic growth (PTG). Current theoretical models cannot fully explain this variability. Therefore, we integrated attachment theory with Ehlers and Clark's model of PTSD to understand whether attachment style is associated with negative appraisals of a traumatic event(s), posttraumatic stress symptoms (PTS), and PTG. Our aim was to test this integrated model PTSD in an analog sample who had experienced at least one traumatic event. Design: We used structural equation modeling to test the association of adult attachment and posttraumatic cognitions (self and world/others) with PTS and PTG using a cross-sectional, correlational design. Methods: The sample comprised 393 university staff and students (Range_Age= 18–49, 85% females) who completed online measures. Results: Attachment anxiety and negative posttraumatic self-cognitions were positively associated. Negative posttraumatic self-cognitions were positively associated with PTS. Attachment anxiety had an indirect effect (via negative posttraumatic self-cognitions) on PTS, whereas attachment avoidance predicted more negative posttraumatic world cognitions and lower perceived PTG. Conclusions: The study highlights the importance of considering how attachment styles influence posttraumatic emotion regulation and cognitive processing of the trauma to determine posttraumatic mental health.     

Exploring Correlates of Alcohol-Specific Social Reactions in Alcohol-Involved Sexual Assaults

This exploratory study examined demographic, assault, and disclosure factors as predictors of survivors’ decisions to disclose preassault alcohol use and social reactions to their preassault alcohol use. Of survivors drinking prior to assault, those with more education and greater alcohol impairment or resistance during assault were more likely to disclose preassault drinking. Of women disclosing preassault drinking, those with more education and more violent assaults received more negative social reactions specific to their preassault drinking. Such negative reactions were more common for those telling parents, police, or medical professionals. Women with less education received more positive and negative social reactions specific to their preassault drinking. Disclosing preassault drinking in greater detail was related to positive social reactions specific to preassault drinking and greater alcohol impairment during assault was associated with both positive and negative social reactions specific to preassault drinking. Implications for research and intervention are provided for survivors disclosing alcohol-related sexual assaults.     

Characterization of the discriminative stimulus effects of lorcaserin in rats

Lorcaserin is approved by the Food and Drug Administration for treating obesity and is under consideration for treating substance use disorders; it has agonist properties at serotonin (5‐HT)_2C receptors and might also have agonist properties at other 5‐HT receptor subtypes. This study used drug discrimination to investigate the mechanism(s) of action of lorcaserin. Male Sprague–Dawley rats discriminated 0.56 mg/kg i.p. lorcaserin from saline while responding under a fixed‐ratio 5 schedule for food. Lorcaserin (0.178‐1.0 mg/kg) dose‐dependently increased lorcaserin‐lever responding. The 5‐HT_2C receptor agonist mCPP and the 5‐HT_2A receptor agonist DOM each occasioned greater than 90% lorcaserin‐lever responding in seven of eight rats. The 5‐HT_1A receptor agonist 8‐OH‐DPAT occasioned greater than 90% lorcaserin‐lever responding in four of seven rats. The 5‐HT_2C receptor selective antagonist SB 242084 attenuated lorcaserin‐lever responding in all eight rats and the 5‐HT_2A receptor selective antagonist MDL 100907 attenuated lorcaserin‐lever responding in six of seven rats. These results suggest that, in addition to agonist properties at 5‐HT_2C receptors, lorcaserin also has agonist properties at 5‐HT_2A and 5‐HT_1A receptors. Because some drugs with 5‐HT_2A receptor agonist properties are abused, it is important to fully characterize the behavioral effects of lorcaserin while considering its potential for treating substance use disorders.
