An evaluation of executive functioning is a critical component of a comprehensive assessment of higher cerebral functioning. The Tinker Toy Test (TTT) was introduced in 1982. This test allows an individual to demonstrate the extent of their executive capacities by permitting them to initiate, plan, and structure a potentially complex activity and carry it out independently in an unstructured fashion and administration is simple.

Show moreAn evaluation of executive functioning is a critical component of a comprehensive assessment of higher cerebral functioning. The Tinker Toy Test (TTT) was introduced in 1982. This test allows an individual to demonstrate the extent of their executive capacities by permitting them to initiate, plan, and structure a potentially complex activity and carry it out independently in an unstructured fashion and administration is simple. This is a departure from more complex and structured tests of executive function. There is a dearth of research on the TTT and this study seeks to examine some of the psychometric properties of this instrument; i.e., working time minimum, gender effects, convergent and divergent validity, and potential intellectual correlates. Participants included 10 male and 30 female student volunteers from a large university in Central Florida. Participants had no history of neurologic disease/trauma or conditions that would affect motor functioning of the upper extremities. Participants completed a demographic questionnaire, the WASI-II, and the TTT. A two-way mixed-design ANOVA examining TTT scores as a function of work time and gender revealed a non-significant gender main effect, F(1, 21) = .09, p = .767. The work time main effect was not significant, , F(1, 21) = .324, p = .575. A significant work time x gender interaction was observed, F(1, 21) = 4.983, p = .037. Convergent validity was assessed by comparing the TTT scores with the Matrix Reasoning subtest, r(38) = .32, p = .044, and the Similarities, r(38) = .34, p = .03, subtest on the WASI-II. Divergent validity was assessed by comparing TTT scores to the Block Design subtest of the WASI-II, r(38) = .245, p = .127. No significant correlation was found between intelligence and TTT (VCI, r(38) = -.16, p = .335; PRI, r(38) = .15, p = .344; and FSIQ, r(38) = -.02, p = .928). The data supports the continued use of the 5-minute working time minimum presented by Lezak, as this temporal index was a more accurate representation of executive functioning. This study demonstrated no association between TTT scores and intellectual functioning. The findings of this study support the validity of this underutilized test of executive functioning and its inclusion in neuropsychological test batteries.

Show moreABSTRACTCardiovascular disease is the leading cause of death for U.S. adults. It adds greater than $100 billion to U.S. health care costs annually. Rates of morbidity, mortality, and economic burden of the disease could be dramatically reduced with improvements in sedentary behaviors among adults with coronary artery disease (CAD). A regular commitment to moderate physical activity can reduce ischemic heart events up to 50%. Although the benefits of physical activity are well-known for individuals with coronary artery disease, an estimated 70% of this population remains relatively sedentary. Hospital-based cardiac rehabilitation programs are the single secondary prevention option offered to improve physical activity habits in persons with CAD. Although effective, cardiac rehabilitation is inaccessible for the majority of CAD sufferers and is offered only after an acute cardiac event. Different from rehabilitation, prehabilitation (prehab) programs use physical activity as a means to deter a worsening condition or prevent injury before an acute event occurs. These programs have proved successful in other areas of medicine but there are currently no such secondary prevention programs available for stable persons with CAD in the U.S. A home-based prehab program could help adults with CAD establish improved physical activity habits and circumvent many of the barriers associated with admission and attendance of a hospital-based cardiac rehabilitation program. Researchers have indicated that self-efficacy is key to initiation and sustentation of a regular physical activity habit, regardless of the physical activity program that one attends. These habits are more likely to last when participants receive self-efficacy based support for an average of 66 days. The purpose of this study was to determine if a nurse-practitioner-led, home-based, prehab program could assist adults with CAD to improve and maintain increased physical activity habits and levels of self-efficacy for physical activity. The five primary facilitators of self-efficacy were used to devise a 10-week prehab program. A convenience sample of 54 adults with diagnosed CAD was recruited from cardiology practices in St. Johns County, Florida. The research population was 68.5% (n=37) male, 88.9% (n=48) Caucasian, and 74% (n=40) married with a mean age of 68.57 years. Participants attended a 90-minute prehab class which offered health education and group discussion of barriers and goals for regular physical activity. Following the class, participants were contacted weekly for 10-weeks to discuss goal progress, assist in circumventing barriers, and revise physical activity goals as needed. After the 10-week call period, participants were contacted 30-days later to assess for physical activity habit maintenance and any sustained benefit in self-efficacy for physical activity. Self-efficacy for exercise was measured before the prehab class, after the prehab class, and after the 10-week intervention period using the Short Self-Efficacy Expectations scale (SSEE), Multidimensional Outcomes Expectations for Exercise Scale (MOEES), and the Barriers Self-Efficacy Scale (BARSE). All baseline measures of self-efficacy (MOEES, BARSE, SSEE) improved significantly immediately following the prehab class. Baseline physical outcome expectations of the MOEES (m=21.87, sd=4.67), self-evaluative outcome expectations of the MOEES (m=16.70, sd=4.15) and SSEE (m=12.75, sd=4.02) remained significantly improved after the 10-week intervention period (p(<).05). At the 10-week assessment, mean significant self-efficacy scores were 24.39 (sd=1.26, p(<).01) for physical outcome expectations, 18.39 (sd=2.27, p(<).02) for self-evaluative outcome expectations, and 15.06, (sd=3.25, p(<).001) for SSEE. The SSEE was reassessed 30-days after the study and remained significantly improved compared to baseline (m=15.65, sd=3.42, p(<).01). Qualitative data collection coincided with the quantitative self-efficacy findings. Participants reported satisfaction with physical activity goal attainment and increased confidence to continue with a regular physical activity plan. The Godin Leisure-Time Exercise Questionnaire (GLTEQ) was used to assess activity levels at baseline, during each weekly phone call, at the end of 10-weeks, and 30-days after the study. Repeated-measures ANOVA (F (2,90) = 21.86, p(<).001) revealed that participant's baseline physical activity volume measured by GLTEQ (m=18.39, sd= 16.93) improved significantly after 10 weeks in the prehab study (m=41.10, sd=24.11, p(<).001) and remained significantly improved when re-measured 30-days after the study (m=39.02, sd=21.87, p(<).001). Qualitative data concurred with quantitative data with participants reporting physical activity habit formation and maintenance of self-regulatory skills. Qualitative data also demonstrated that participants in prehab experienced very similar facilitators and barriers compared to other adults with CAD attempting an exercise program. In summary, the prehab study findings coincided with other research findings in this area. Self-efficacy based support can assist individuals with CAD to improve and maintain physical activity habits. The ease of the intervention likely contributed to lower cost and attrition rates (7%) compared to hospital-based cardiac rehabilitation programs. Although more research is needed, study findings suggest that a nurse-practitioner-led, home-based program could be a viable secondary prevention strategy for stable adults with CAD. This should be considered for the future given that even modest improvements in physical activity can substantially reduce all-cause mortality in this population.

Show moreProblem: In recent years, childhood obesity has increased to epidemic proportions across the United States (U.S.) in parallel with adult obesity, which often reflects poor dietary choices and bad nutritional habits. Purpose: The primary purpose of this study was to examine the effects of parent and adolescent nutrition literacy expressed as nutrition knowledge and skills, with total household income and parent level of education, as predictors of weight status in adolescents that live in a Florida community. The secondary purpose of this study was to examine the implications for nutrition literacy levels within parent/adolescent dyads to identify public health initiatives aimed at adult and adolescent populations.Methods: A descriptive, correlational design was used to collect data from a convenience sample of 110 parent-adolescent dyads recruited from a free physical exam event hosted by a local health care facility. Three instruments were completed by each dyad: 1) demographic survey, 2) Nutrition Literacy Survey (NLS; knowledge), and 3) Newest Vital Sign (NVS; skills). Physiologic measurements for the study included anthropometric measurement of the adolescent child's height (cm) and weight (kg) without shoes and BMI scores were calculated. In addition to actual value, BMI was categorized as low/normal and overweight/obese for analysis. Paired t-tests were used to compare means for the NLS and NVS survey in parent-adolescent dyads. Bivariate correlation scores were computed between the two variables of parent/adolescent NLS and NVS scores. Lastly, regression models for examining adolescent BMI were compared with the independent variables of the study.Results: The sample of adult participants (n =110) comprised males (n = 30, 27%) and females (n =80, 73%) ranging in age from 34 to 55 years (M= 41.9, SD= 4.77). Adolescent participants (n=110) comprised males (n = 61, 55%) and females (n = 49, 45%) ranging in age from 13 to 17 years (M = 15.1, SD = 1.43). Adolescent male participants had higher BMI (27 + 3.48) than females (24 + 2.90), t (108) = 4.83, (p = (<) .001). Adolescent males were categorized more overweight/obese than females (67.2% versus 24.5%). The parent NLS mean score (M=19) indicated low overall levels of general nutrition knowledge whereas the adolescent NLS mean score (M=21.7) demonstrated greater aptitude for nutrition knowledge than parent scores. The parent NVS mean score (M=4.1) suggested adequate levels of nutrition skills. Likewise, the adolescent NVS mean score (M= 4.1) suggested adequate nutrition skills, similar to scores in the adult population. Spearman rho correlations yielded positive correlations between parent/adolescent nutrition knowledge, (rs = .224, p = .019), and parents' nutrition knowledge and skills (rs = .596, p (<) .001). Positive correlations were also noted between adolescents' nutrition knowledge and parents' nutrition skills (rs = .257, p = .007) and adolescents' nutrition knowledge and nutrition skills (rs = .260. p = .006). Three regression models were calculated to examine adolescent BMI with the independent variables of the study. Analysis of regression coefficients for each model indicated that none of the variables demonstrated significance as a predictor of adolescent BMI.Discussion/Implications: The results of the study suggest that parents and adolescents may have similar amounts of nutrition literacy when examining the constructs of nutrition knowledge and skills; however, BMI is not solely dependent on these skill sets. Examination of the factors that influence parents and adolescent children's weight status are important elements in shaping families adoption of sound dietary habits and improving health outcomes.
