A confirmatory factor analytic approach on perceptions of knowledge and skills in teaching (PKST)

This paper reports the cross-validation of the factor pattern of the Perceptions of Knowledge and Skills in Teaching (PKST) survey, which was used to assess the self-perceived pedagogical knowledge and skills of pre-service and beginning teachers. The sample comprised 323 pre-service teachers enrolled in a 1-yr. post-graduate teacher education program in Singapore. The survey had 37 items distributed across six scales: student learning, lesson planning, instructional support, accommodating diversity, classroom management, and care and concern. A confirmatory factor analysis (CFA) was used to cross-validate the survey's factor pattern. The results showed that the model was an acceptable fit to the data. The PKST survey can thus be adapted by different teacher education programs to assess pre-service and beginning teachers' progress in developing their pedagogical knowledge and skills.     

Neighborhood Risk and Interpersonal Support as Predictors of Parents’ Sense of Community

Parents’ sense of community (SOC) may ease the impact of neighborhood risk on children’s outcomes, but not all parents feel part of a trusted community. In this study, we examined whether parents’ ratings of neighborhood risk and interpersonal support were related to their SOC, and whether interpersonal support moderated the relationship between neighborhood risk and parents’ SOC. Participants included 161 parents (M?=?40.25 years; 92.3% female) of minor children who were enrolled in youth mentoring programs. Results indicated that greater interpersonal support and less neighborhood risk was associated with parents’ SOC. Post-hoc analyses showed that living in a neighborhood with gangs and illegal drugs, but not residential instability or living in public housing, was a salient risk factor for lower SOC. Contrary to our prediction, interpersonal support did not moderate the link between neighborhood risk and parents’ SOC. These findings may inform interventions designed to bolster parents’ connectedness to community and ability to promote children’s positive development.

     

Effect of Persuasive Appeals in AIDS PSAs and Condom Commercials on Intentions to Use Condoms1

The study compared the effect of five persuasive appeals used in AIDS PSAs and condom commercials (fear arousal-no sex/condom theme; fear arousal-sex/condom theme; erotic; humorous; factual) on 122 male and 114 female college students' i]ntentions to use and taking of condoms. Results showed that the two fear appeals were more effective than other appeals in increasing intentions to use condoms with a new partner. The fear appeal–no sex/condom theme was more effective than other appeals for increasing intentions to use condoms with a steady partner. Compared to men, women rated commercials as more effective for increasing intentions to use condoms with a new partner. Persuasive appeals had no effect on the taking of free condoms. The best predictor of commercial effectiveness was the degree to which a commercial evoked a high fear of AIDS. Other significant predictors were subjects' a]ttitude toward condom use and commercial qualities of being humorous, romantic, credible, and factual. Implications are that all five types of appeals are potentially effective for use in AIDS PSAs. Recommendations include combining appeals (e.g. fear with erotic) and emphasizing the positive features of condom use.     

ANALYSIS OF A HIGH-PROBABILITY INSTRUCTIONAL SEQUENCE AND TIME-OUT IN THE TREATMENT OF CHILD NONCOMPLIANCE

This study evaluated the effectiveness of high-probability requests and time-out as treatments for noncompliance that appeared to be maintained by contingent attention in 2 developmental normal children. The introduction of high-probability requests increased compliance for 1 child but not the other. Time-out was effective with both children, and improvements in compliance were maintained at an 8-week follow-up.     

Patient-Informed Treatment Development of Behavioral Smoking Cessation for People With Schizophrenia

The objective of this study was to use qualitative methodology to tailor and refine an existing smoking cessation intervention for the population of people who use cigarettes and are diagnosed with schizophrenia, schizoaffective, or psychotic disorder. Successive cohort design methodology was used to iteratively modify the treatment in response to qualitative participant, therapist, and consultant feedback on the intervention. Qualitative methodology for participant feedback included analysis of semistructured interviews with participants, visualization of app utilization data, and stakeholder feedback from study therapists and consultants. Using the successive cohort design, a tailored multicomponent mobile health smoking cessation intervention was developed. The intervention included mobile contingency management (i.e., financial compensation for confirmed abstinence from smoking), pharmacotherapy for smoking cessation, cognitive-behavioral counseling sessions, and the Stay Quit app for relapse prevention. Two cohorts (N = 13) were completed in the study; after each cohort, the treatment protocol was revised. The intervention is described, as well as the qualitative findings from each cohort and subsequent changes made to the intervention based upon patient and provider feedback. Metrics of patient engagement included treatment adherence (40% in Cohort 1 and 63% in Cohort 2). Both participants and therapists reported that the intervention was helpful. Over one third of participants self-reported abstinence at posttreatment. Since qualitative methodology is often underutilized in mental health treatment development, this study demonstrates the utility of the successive cohort design for treatment development of behavior change interventions for at-risk, vulnerable populations.     

Perceptual integration of tertiary taste mixtures

Integration psychophysics was used to explore the taste perception of mixtures of sucrose, fructose, and citric acid. Three levels of each stimulus were varied in a 3 x 3 x 3 factorial design. Subjects rated total intensity, sweetness, and acidity of the 27 mixtures on graphic rating scales. Consistent with earlier work, the perceived total intensity of the tertiary mixtures was found to be dictated by the intensity of the (subjectively) stronger component alone (i.e., either the integrated sweetness or the acidity, whichever was the more intense). In contrast, the sweetness and acidity of the mixture were susceptible to mutual suppression: Sweetness suppressed acidity, acidity suppressed sweetness. There was, however, a difference between sucrose and fructose in their interactions with citric acid, fructose being the more susceptible to suppression. This selectivity of suppression indicates that the two sweetnesses could not have been inextricably integrated. Implications for taste coding are discussed, and the findings are reconciled in terms of two separate coding mechanisms: one for taste intensity, another for taste quality.
