Distant intentionality and the feeling of being stared at: two meta-analyses.

Findings in parapsychology suggest an effect of distant intentionality. Two laboratory set-ups explored this topic by measuring the effect of a distant intention on psychophysiological variables. The 'Direct Mental Interaction in Living Systems' experiment investigates the effect of various intentions on the electrodermal activity of a remote subject. The 'Remote Staring' experiment examines whether gazing by an observer covaries with the electrodermal activity of the person being observed. Two meta-analyses were conducted. A small significant effect size (d =.11, p =.001) was found in 36 studies on 'direct mental interaction', while a best-evidence-synthesis of 7 studies yielded d =.05 (p =.50). In 15 remote staring studies a mean effect size of d = 0.13 (p =.01) was obtained. It is concluded that there are hints of an effect, but also a shortage of independent replications and theoretical concepts.

Evidence that the type of person affects the strength of the perceived behavioural control-intention relationship.

This study examined the role of person type in explaining the relationship between perceived behavioural control and behavioural intentions. Participants (N = 187) completed measures of the theory of planned behaviour (Ajzen, 1991) variables regarding 30 behaviours. Within-participants analyses demonstrated that intentions were more strongly predicted by perceived behavioural control (PBC) than a combination of attitudes and subjective norms among a minority of the sample. When these 'PBC controlled' participants were considered separately, the effects for perceived behavioural control obtained in previous between-participants analyses were augmented. Conversely, when these participants were excluded from the sample, the effects of perceived behavioural control were reduced. PBC control was also modestly associated with dispositional measures of perceived controllability. Overall, the findings indicate that the strength of the perceived behavioural control-intention relationship depends not only on the type of behaviour but also on the type of person.

Using the theory of reasoned action to explain physician intention to prescribe emergency contraception.

CONTEXT: Although research has examined providers' knowledge, attitudes and prescribing behaviors with regard to emergency contraception, none has used a theory-based approach to understanding the interplay of these factors. METHODS: A cross-sectional survey of 96 faculty physicians from one Southern and three Midwestern universities was conducted in 2004 to assess factors associated with intention to prescribe emergency contraception. The theory of reasoned action guided the study hypotheses and survey design. Correlation and regression analyses were used to examine the data. RESULTS: Only 42% of respondents strongly intended to prescribe emergency contraception for teenagers, but 65-77% intended to do so for all other specified groups (women who ask for the method, who have had a method problem, who have experienced rape or incest, and who have had unprotected sex). Consistent with the theory of reasoned action, high intention to prescribe emergency contraception was associated with positive attitudes toward doing so and with the perception that specific colleagues or professional groups support prescribing it; however, the perception of support by colleagues or professional groups in general did not predict intention. Also consistent with the theory, physicians' knowledge about emergency contraception and their demographic characteristics were not significant. CONCLUSIONS: Interventions to encourage physicians to provide emergency contraception should take into account their attitudes toward the method and the components of those attitudes.

First intention high-frequency oscillation with early lung volume optimization improves pulmonary outcome in very low birth weight infants with respiratory distress syndrome.

OBJECTIVES: The lack of decline in chronic lung disease of prematurity despite the generalized use of surfactant and alternative modes of ventilation such as high-frequency oscillation (HFO) has been attributed to some misunderstanding of how HFO has to be used. We used a new ventilatory strategy in very low birth weight (VLBW) infants, by initiating HFO immediately after intubation and attempting early lung volume optimization before surfactant was administered. STUDY DESIGN: The outcome of 32 VLBW infants, managed with first intention HFO over a period of 24 months (September 1, 1996 and August 31, 1998) was compared by chart review with 39 historical controls, consecutively managed with conventional mechanical ventilation (CMV) over a period of 24 months (January 1, 1994 and December 31, 1995). SETTING: An 11-bed tertiary care pediatric and neonatal intensive care unit of a university teaching hospital. RESULTS: The 2 groups of patients were similar in demographic distribution of birth weight, gestational age, race, and gender. Patients on first intention HFO were ventilator-dependent (median [95% confidence interval]: 5 [3-6] vs 14 [6-23] days) and oxygen-dependent (12 [4-17] vs 51 [20-60] days) for a shorter time than patients on CMV. The incidence of chronic lung disease at 36 weeks of gestational age was significantly lower in the HFO group compared with the CMV group (0% vs 34%). CONCLUSIONS: First intention HFO with early lung volume optimization shortened the need for respiratory support and improved pulmonary outcome of VLBW infants with respiratory distress syndrome significantly.

Intentional coverage of a main renal artery during endovascular juxtarenal aortic aneurysm repair in symptomatic high-risk patients.

PURPOSE: To describe the efficacy and morbidity of intentionally covering a main renal artery during symptomatic juxtarenal endovascular aneurysm repair (EVAR). CASE REPORTS: Two patients with symptomatic juxtarenal abdominal aortic aneurysm (AAA) were felt to be at prohibitive risk for open repair. Each underwent EVAR with intentional coverage of 1 main renal artery to achieve adequate proximal hemostatic seal. One patient died at 24 months; the second is symptom-free at 10 months. Both aneurysms initially decreased in diameter. Both patients had increased serum creatinine and required increased therapy for hypertension, but neither required hemodialysis. Renal volume decreased 48.7% and 68.0%, respectively. CONCLUSION: Intentional coverage of a main renal artery during EVAR for a symptomatic juxtarenal aneurysm resulted in effective short-term AAA repair with no need for dialysis. Despite the increased requirement for antihypertensive medications and the observed decline in renal function, this technique provides an option for treatment of this difficult patient subset.

[Evaluation of the quality of mortality information by unspecified accidents and events of undetermined intent].

INTRODUCTION: Mortality data are important for monitoring violence, making it possible to assess the trends and the impact of interventions towards its reduction. The objective of the study is to assess the quality of the filling out and codification of the death certificates for unspecified accidents and events of undetermined intent in the city of S. Paulo in 1996. METHODS: Death certificates on which the underlying cause of death (UCD) given was an unspecified accident (ICD-10 X59) or an event of undetermined intent (ICD-10 Y10-Y34) were selected for investigation at the Legal Medicine Institute (IML). After consulting the police reports which accompany the corpses to the IML, the autopsy reports and other legal forms, these were analysed and the UCD was recoded. RESULTS: For unspecified accidents, 53.2% were changed to a specified cause: 15.1% due to pedestrians injured in traffic accidents, 17.5% due to other traffic accidents and 14.5% due to falls. Homicides and suicides constituted 9.8%. In 20.9% no additional information was found. For events of undetermined intent, 2/3 had no clarification; in 1/3 of the cases, the underlying cause changed to falls (10.6%), homicides (7.5%) and pedestrians injured in transport accidents (6. 7%). CONCLUSIONS: The quality of mortality information by external causes in the City of S. Paulo is not satisfactory. The IML has not used all the available information to fill out the death certificates. The findings reveal that the instruction of the World Health Organization and the Brazilian Center for the Classification of Diseases to codify as accidents those events for which there is no information on the death certificate about the external cause, does not seem to be appropriate. In that category 66.0% of the deaths were found to have been inferred incorrectly as accidental. The improvement of the quality of mortality data due to external causes may contribute to the monitoring of violence and may give support to decisions leading to its reduction whatever the form that violence may take.

Intentional overdose with insulin glargine and insulin aspart.

Reports of intentional massive overdoses of insulin are infrequent. A review of the literature revealed no reports of overdose attempts with either insulin glargine or insulin aspart. We report the case of a 33-year-old woman without diabetes mellitus who intentionally injected herself with an overdose of both products, which belonged to her husband. She arrived at the emergency department 15 hours after her suicide attempt, which took place the night before. Her husband had checked her blood glucose level throughout the night and had given her high-carbohydrate drinks and foods. The patient had a history of obsessive-compulsive disorder, major depression, and numerous suicide attempts. She recovered from the resulting hypoglycemia after 40 hours of dextrose infusion and was transferred to a mental health facility. The main danger associated with insulin overdose is the resultant hypoglycemia and its effects on the central nervous system; hypokalemia, hypophosphatemia, and hypomagnesemia also can develop with excess insulin administration. Dextrose infusion, with liberal oral intake when possible, and monitoring for electrolyte changes, making adjustments as needed, are recommended for the treatment of intentional insulin overdose.

Questionnaire development to predict mammography intention among women in southeastern Louisiana.

This article summarizes the development and psychometric analysis of the Thoughts About Mammography (TAM) questionnaire to predict mammography intention using the Theory of Planned Behavior (TPB). Key themes, obtained from elicitation interviews (N = 45), were categorized, ranked and extracted for item construction. Initial pilot testing supported test-retest reliability (alpha = .85 to .97), internal consistency (alpha = .67 to .91), and content validity (0.86-1.00). After pilot testing, the TAM was administered to 302 rural women in southeastern (SE) Louisiana. The instrument was internally consistent (alpha = 0.77 to 0.92), construct valid (alpha = .18 to .64), and predicted 24% of the variance of mammography intention. The TAM adequately demonstrated reliability and validity to measure mammography intention in rural southeastern Louisiana women.

Goal expectations as predictors of retirement intentions.

The current study explored the contribution of personal goals to retirement decisions. A SMARTER methodology (to assess multiattribute utility) and taxonomy of human goals were used to investigate the relationship between older workers' personal goals and their retirement intentions. Two hundred and fifty-one employees of a large university, varying in age from 55 to 77, were asked to indicate the relative importance of 29 goals and to indicate the utility they perceived in continued work and retirement as a means to achieve these goals. The results demonstrate that goal evaluations are important predictors of retirement intentions. Furthermore, goal evaluations provide an important and unique contribution to predicting retirement intentions beyond that predicted by personal and demographic variables. These results have implications for pre-retirement education and workplace application.

Evaluation of a tobacco prevention program on knowledge, attitudes, intention and behavior of tobacco use among fourth grade students--a preliminary study.

This was a preliminary study to evaluate the effectiveness of a tobacco prevention program on knowledge, attitude, intention, and behavior of tobacco use among fourth-grade students in four north central Florida counties. The results suggest that the program was effective in improving students' knowledge, attitudes, and intention toward not using tobacco products. Data analysis showed that students in the education group had a greater improvement in knowledge than the comparison group. Students in the education group also improved their attitude and intention scores while the comparison group did not show any improvement. The results also indicated positive responses from the students. In addition, teachers also gave a very positive response to the program.

Impact of perceived second-hand consequences related to alcohol use on college students' drinking behavior intent: a test of feasibility.

This article presents the results of an experiment designed to determine the impact of a group discussion about second-hand consequences of alcohol use on college students' intentions to consume alcohol. Participants were students enrolled in two large Community Health courses at a large Midwestern university (n = 184). After randomization of class sections into an intervention or a control group, intervention group students participated in a class discussion on the negative consequences college students experience as a result of other students' drinking behavior, prior to answering survey questions regarding their drinking behavior intent. Compared to controls who completed the questionnaire only, intervention group participants reported intent to limit themselves to fewer drinks per drinking occasion (p = .003) and fewer drinks per week (p = .004). The effects of the brief educational intervention were analyzed using structural equation modeling, to test the feasibility of a hypothesized intervention mechanism.

The Krantz Health Opinion Survey: correlations with preventive health behaviors and intentions.

The Krantz Health Opinion Survey, a measure of treatment preferences, was administered to 124 college women who also completed the Multidimensional Health Locus of Control Scale and rated their own preventive health behaviors and intentions. Analysis confirmed previous findings of relations between the two scales, particularly the moderate negative correlation between the Krantz Behavioral Involvement Scale and Powerful Others Locus of Control. The Krantz scores also were correlated with demographic measures such as education and occupation of the head of the household. With the exception of low correlations with frequency of obtaining Pap tests and with intentions to engage in exercise, the Krantz scores were uncorrelated with preventive health behaviors and intentions. It may be that another variable such as health value moderates these associations.

Determinants of intentions of Junior High School students to become sexually active and use condoms: implications for reduction and prevention of AIDS risk.

The purpose of this study was to examine factors associated with young adolescents' increased risk for AIDS. A multiethnic sample of 303 seventh-grade students in three schools in the greater New York area completed questionnaires assessing their basic demographic characteristics (gender and ethnicity), AIDS knowledge, substance use (cigarette smoking, alcohol use), and decision-making skills. AIDS knowledge, substance use, decision-making skills, gender, and ethnicity predicted intentions to engage in sexual behavior in the future. Relevant knowledge of AIDS was associated with lower intentions to engage in sexual behavior in the future. More frequent substance use, less frequent use of decision-making skills, and being male increased intentions to engage in sexual behavior in the future. Our findings are discussed in terms of their implications for education and prevention of adolescent sexual activity and AIDS-risk reduction.

Facilitating changes in exercise behavior: effect of structured statements of intention on perceived barriers to action.

Two groups of worksite employees (58 in a control, 53 in an experimental group) underwent three 90-min. educational sessions designed to increase participation in exercise. At the end of the third session, experimental subjects were asked to complete a structured statement of exercise intention which addressed the major barrier to exercise. Two weeks following the program, chi-squared analysis showed that the two groups were proportionately different in changes in frequency and intensity of exercise such that the experimental group in both cases showed greater changes than the control. Experimental subjects showed a twofold increase in frequency and intensity of exercise over the control group. Pearson r indicated a statistically significant association between the completeness of structured statements of intention and an increase in frequency of exercise. We conclude that structured statements of intention are useful for distinguishing between contrived barriers to exercise (excuses) and actual barriers that require practical solutions.

Effects of deceptive packaging and product involvement on purchase intention: an elaboration likelihood model perspective.

From an Elaboration Likelihood Model perspective, it was hypothesized that postexposure awareness of deceptive packaging claims would have a greater negative effect on scores for purchase intention by consumers lowly involved rather than highly involved with a product (n = 40). Undergraduates who were classified as either highly or lowly (ns = 20 and 20) involved with M&Ms examined either a deceptive or non-deceptive package design for M&Ms candy and were subsequently informed of the deception employed in the packaging before finally rating their intention to purchase. As anticipated, highly deceived subjects who were low in involvement rated intention to purchase lower than their highly involved peers. Overall, the results attest to the robustness of the model and suggest that the model has implications beyond advertising effects and into packaging effects.

Predicting intentions to seek help from professional mental health services.

OBJECTIVE: This study investigates the factors related to the intention to seek professional help for psychological problems utilising Ajzen and Fishbein's theory of reasoned action. Many of the variables identified in previous studies can be subsumed within this theory, which emphasises the importance of the subjective point of view of the individual. METHOD: One hundred and forty-two patients waiting for consultations at a community based general practice completed a questionnaire designed to assess the components of this theory as they relate to seeking help from mental health professionals. RESULTS: The results of this study supported the prediction of the intention to seek help from a mental health professional from the variables 'attitude toward the behaviour' and 'subjective norm'. However, personal attitudes toward seeking help were found to be more important than the approval or disapproval of significant others in predicting help-seeking intentions. CONCLUSIONS: Overall, the findings indicate that a significant factor influencing people's decisions to utilise professional mental health services in Australia may be the belief that mental health professionals are not actually able to provide a great deal of help or support for people's difficulties.

The effects of skills and intentions to use drugs on posttreatment drug use of adolescents.

The present study examines the relationship between (a) social, cognitive, and behavioral skills; (b) self-reported intentions to use drugs and alcohol following treatment; and (c) later drug and alcohol use for a sample of 130 adolescents. Social, problem solving, self-control, and drug and alcohol avoidance skills were significantly related to marijuana use, variety and severity of drug use, and to the number of drug-free months for female subjects at 12-month follow-up. These skills did not have a statistically significant direct effect on any measured drug outcomes for males. However, skills did lower male subjects' intentions to use drugs or alcohol. Decreased intentions to use, in turn, were associated with less drug and alcohol use, suggesting an indirect relationship between skills and reductions in drug and alcohol use among males at 12-month follow-up. Implications for the treatment of adolescents who engage in drug and alcohol use are discussed.

Interpersonal influences on male drug use and drug use intentions.

The relationship between (1) the respondent's perception of the drug behavior of his father, mother, siblings, current friends, and wife/female partner; and (2) past drug use and future drug use intentions for tobacco, alcohol, marijuana, psychedelics, stimulants, sedatives, heroin, other opiates, and cocaine is examined among a representative sample of men in the U.S. population who were 20-30 years old in 1974 (N = 2,510). For each drug the results indicated that current friends' and wife/partner's drug behaviors are the factors most strongly associated with the respondent's past drug use as well as his intentions of future drug use. Although substantially less important, siblings' drug behavior also appears to be a source of influence, while the drug behavior of mothers and fathers is only minimally associated with drug use and future intentions.
