The Effects of Message Framing on Mammography Utilization

This experiment compared the effectiveness of gain-versus loss-framed messages to persuade women to obtain mammography screening. One hundred and thirty-three women 40 years and older and not adhering to current guidelines for obtaining mammography screening were assigned randomly to view either gain-framed (emphasizing the benefits of obtaining mammography) or loss-framed (emphasizing the risks of not obtaining mammography) persuasive videos that were factually equivalent. Attitudes and beliefs were measured before and immediately following the intervention. Mammography utilization was assessed 6 and 12 months later. Consistent with predictions based on prospect theory, women who viewed the loss-framed message were more likely to have obtained a mammogram within 12 months of the intervention. These findings suggest that loss-framed messages may have an advantage in the promotion of detection behaviors such as mammography.

Cue-dose Training with Monetary Reinforcement: Pilot Study of an Antiretroviral Adherence Intervention

AbstractOBJECTIVE: To assess the feasibility and efficacy of two interventions for improving adherence to antiretroviral therapy regimens in HIV-infected subjects compared with a control intervention. DESIGN: Randomized, controlled, pilot study. SETTING: Department of Veterans Affairs HIV clinic and community-based HIV clinical trials site. PARTICIPANTS: Fifty-five HIV-infected subjects on stable antiretroviral therapy regimens. Subjects were predominantly male (89%) and African American (69%), and had histories of heroin or cocaine use (80%). INTERVENTIONS: Four weekly sessions of either nondirective inquiries about adherence (control group, C), cue-dose training, which consisted of the use of personalized cues for remembering particular dose times, and feedback about medication taking using Medication Event Monitoring System (MEMS) pill bottle caps, which record time of bottle opening (CD group), or cue-dose training combined with cash reinforcement for correctly timed bottle opening (CD+CR). MEASUREMENTS: Opening of the pill bottle within 2 hours before or after a predetermined time was measured by MEMS. RESULTS: Adherence to the medication as documented by MEMS was significantly enhanced during the 4-week training period in the CD+CR group, but not in the CD group, compared with the control group. Improvement was also seen in adherence to antiretroviral drugs that were not the object of training and reinforcement. Eight weeks after training and reinforcement were discontinued, adherence in the cash-reinforced group returned to near-baseline levels. CONCLUSIONS: Cue-dose training with cash reinforcement led to transient improvement in adherence to antiretroviral therapy in a population including mostly African Americans and subjects with histories of drug abuse. However, we were not able to detect any sustained improvement beyond the active training period, and questions concerning the timing and duration of such an intervention require further study. Randomized, controlled clinical studies with objective measures of adherence can be conducted in HIV-infected subjects and should be employed for further evaluation of this and other adherence interventions.

Factors related to academic success among nursing students: A descriptive correlational research study

BACKGROUND The current rise in employment is improving forecasts for the future supply of registered nurses; however sizeable shortages are still projected. With the intention of improving academic success in nursing students, related factors need to be better understood. OBJECTIVES The purpose of the correlational study was to describe the relationship between emotional intelligence, psychological empowerment, resilience, spiritual well-being, and academic success in undergraduate and graduate nursing students. DESIGN/SETTING A descriptive correlational design was utilized. The study was set in a private Catholic university. PARTICIPANTS There were 124 participants. There were 59% undergraduate and 41% graduate students. METHODS Background data, in addition to the Spreitzer Psychological Empowerment Scale, the Wagnild and Young Resilience Scale, and the Spiritual Well-Being Scale and the Mayer-Salovey-Caruso Emotional Intelligence Test, was collected from students who met study criteria. RESULTS In a combined sample, academic success was correlated with overall spiritual well-being, empowerment and resilience. Although academic success was not correlated with overall emotional intelligence, it was correlated with the emotional intelligence branch four (managing emotions) score. When undergraduate and graduate students were considered separately, only one correlation was found to be significantly related to academic success in the undergraduate sample, namely, emotional intelligence branch one (perceiving emotions). When examining the data from just graduate level nurses, significant relationships were found between total emotional intelligence with academic success, resilience with academic success, and psychological empowerment with academic success. CONCLUSION The significant relationship between psychological empowerment, resilience, spiritual well-being and academic success in this study supports the statements in the literature that these concepts may play an important role in persistence through the challenges of nursing education. Research is needed to examine if strategies to enhance empowerment, resilience, and spiritual well-being can increase academic success in a test-retest design.

Perfusion abnormalities and decision making in cocaine dependence.

BACKGROUND Previous studies have shown that cocaine abusers have cerebral perfusion deficits that may diminish cognitive functioning. This study examined whether cocaine-dependent patients have perfusion abnormalities associated with poor decision-making ability as measured by the Iowa Gambling Task (IGT). METHODS Seventeen abstinent cocaine-dependent patients were administered the IGT after completion of resting 99mTc-HMPAO single-photon emission computed tomography (SPECT). RESULTS Better IGT performance was negatively correlated with perfusion within the anterior cingulate gyrus, middle frontal gyrus, medial frontal gyrus, and superior frontal gyrus. The time to complete card selections was positively correlated with the severity of impairment. CONCLUSIONS Resting hyperperfusion in brain regions previously implicated in decision making and response inhibition was associated with worse IGT scores. Impaired performance was related to a greater amount of time taken for card selections, suggesting that reduced ability was due to cognitive factors other than an impulsive response pattern.

Neuropsychological Correlates of Suboptimal Adherence to Metformin

The goal of this study was to determine if neuropsychological function is associated with adherence to prescribed medication. Altogether, 79 patients with type II diabetes at a VA primary care clinic had adherence to the antihyperglycemic drug metformin measured with MEMS® caps over a 4-week period. They completed several tests of neuropsychological function: Mini-Mental Status Exam (MMSE), Trails A and B, Stroop, Digit Span, Digit Symbol, and Grooved Pegboard. In separate multivariate analyses, Stroop word score and time to complete Trails B were independently associated with adherence, as was age. Secondary analyses of the relationship between neuropsychological variables and other adherence-related measures were conducted. Low scores on the MMSE and non-Caucasian ethnicity were associated with missed appointments. None of the neuropsychological variables were associated with glycosylated hemoglobin. These results suggest that cognitive abilities should be considered when counseling patients concerning their adherence.

Examining the effect of cerebral perfusion abnormality magnitude on cognitive performance in recently abstinent chronic cocaine abusers.

Background and Purpose. Cerebral perfusion abnormalities and neuropsychological impairment are common sequelae of chronic cocaine abuse. While perfusion abnormalities have been shown to relate to cognitive deficits in this substance abuse population, the relationship between cognitive performance and the magnitude of perfusion abnormality has yet to be fully determined. Methods. Thirty‐seven abstinent cocaine abusers and 13 normal controls were administered resting 99m‐Tc‐HMPAO single photon emission computed tomography (SPECT) scans followed by a neuropsychological assessment battery tapping executive skills, attention, memory, and motor performance. Statistical parametric mapping (SPM99) techniques were used to analyze the SPECT data to detect significant regional perfusion abnormalities in the cocaine group relative to normal controls, and resulting abnormal SPECT counts were employed for comparison with the assessment measures to examine the relationship between cocaineinduced perfusion abnormalities and cognitive performance. Results. SPECT data analysis revealed significant regional perfusion abnormalities in the cocaine abuse sample relative to controls and significant differences in neuropsychological functioning on measures of executive functioning, complex attention, memory, and manual dexterity. For chronic cocaine abusers, however, within‐group comparisons of the magnitude of abnormal perfusion and neuropsychological performance were largely nonsignificant, with the exception of complex attention and motor speed. Conclusions. Perfusion abnormalities and neuropsychological impairments readily distinguished cocaine abusers from normal controls. However, when the magnitude of cocaine‐induced perfusion abnormalities is examined in relation to cognitive performance, motor speed and complex attention appear to be the best behavioral indicants of the severity of perfusion dysfunction within this substance abuse population.

The effect of alcohol on the neuropsychological functioning of recently abstinent cocaine-dependent subjects.

Neuropsychological deficits in the areas of learning, memory, attention, and abstraction abilities have been associated with cocaine dependence, especially during the period of early abstinence. Although cocaine users tend to be multidrug users, few studies have focused on the combined effect of alcohol and cocaine on neuropsychological functioning. Consistent with prior research, results from the current study indicated that cocaine-dependent subjects showed a significantly greater degree of neuropsychological impairment as compared to controls. In addition, cocaine-dependent subjects with a history of alcohol disorder showed less memory impairment but similar impairments in attention and overall neuropsychological functioning as cocaine subjects with no such history. The vasodilatation produced by alcohol may attenuate some of the vasoconstriction and neurotoxic effects of cocaine, accounting for the fewer deficits in this group.

Reducing the fear of falling through a community evidence-based intervention

Falls and the fear of falling are major health concerns among older adults. The purpose of this study was to assess the effects of an evidence-based fall prevention program on the fear of falling and health-related quality of life among community-dwelling elders. The program consisted of 6 classes that covered topics such as risk factors for falls, balance exercises, medications, safe footwear, and home safety. Of those elders who were most fearful at baseline, the fall prevention program decreased their fear of falling and improved 1 dimension of their health-related quality of life.
