[Digital transformation of perioperative nurse-coordinated protocols in renal surgery for enhanced recovery and outpatient surgery using UroConnect® application]. / Digitalisation de la coordination infirmière des parcours périopératoires de chirurgie rénale en réhabilitation améliorée et ambulatoire par l'application UroConnect®.

Robot Assisted Partial Nephrectomy (RAPN) is a standard of care for localized renal tumors. It allows a good carcinological control while limiting complications. Despite numerous benefits, the economic sustainability of robotic assistance remains a challenge in the French health care system. The introduction in our institution of two perioperative nurse-coordinated protocols for patients undergoing RAPN (Enhanced Recovery After Surgery: NP-RAAC in 2015 and Outpatient: Ambu-Rein in 2016) is associated with a shortening of the average length of hospital stay, thus reducing the cost of robotic assisted procedures. With the aim of improving efficiency of nursing support within these protocols, we have introduced digitalized nursing coordination by developing a urological perioperative application: UroConnect®. This device is offered to patients by the coordinating nurses during a preoperative visit. It provides information on the pathology and its surgical management. Self-completed questionnaires sent at key moments collect data from the first month after surgery and detect patients presenting difficulties or complications, allowing the nurses to respond with appropriate care. The application allows a secure discharge, a personalised follow-up and an increase in the patient's autonomy and compliance with care.

[Comprehensive review of 3D printing use in medicine: Comparison with practical applications in urology]. / Revue compréhensive de l'apport de l'impression 3D en médecine : mise en perspective des différentes applications en urologie.

INTRODUCTION: Over the past few years, 3D printing has evolved rapidly. This has resulted in an increasing number of scientific publications reporting on the medical use of 3D printing. These applications can range from patient information, preoperative planning, education, or 3D printing of patient-specific surgical implants. The objective of this review was to give an overview of the different applications in urology and other disciplines based on a selection of publications. METHODS: In the current narrative review the Medline database was searched to identify all the related reports discussing the use of 3D printing in the medical field and more specifically in Urology. 3D printing applications were categorized so they could be searched more thoroughly within the Medline database. RESULTS: Three-dimensional printing can help improve pre-operative patient information, anatomy and medical trainee education. The 3D printed models may assist the surgeon in preoperative planning or become patient-specific surgical simulation models. In urology, kidney cancer surgery is the most concerned by 3D printing-related publications, for preoperative planning, but also for surgical simulation and surgical training. CONCLUSION: 3D printing has already proven useful in many medical applications, including urology, for patient information, education, pre-operative planning and surgical simulation. All areas of urology are involved and represented in the literature. Larger randomized controlled studies will certainly allow 3D printing to benefit patients in routine clinical practice.

[Use of personalized 3D printed kidney models for partial nephrectomy]. / Utilisation de l'impression 3D avant néphrectomie partielle pour tumeur du rein.

Partial nephrectomy is a first-line treatment option for the management of renal tumors. It is a surgical procedure whose complexity and stakes vary according to the specific anatomy of the patient and his tumor. 3D modeling and 3D printing have become a means of representing and thus visualizing the tumor lesion and its anatomical relationships within the organ. This mode of visualization allows the surgeon and his team, but also the patient, to easily realize the tumor complexity, the predictable difficulty of the surgery and therefore the risks of complications. Various publications have reported the benefit to the patient in terms of pre-therapy education. Some have shown a benefit for the operator in terms of surgical planning. Finally, studies on preoperative surgical simulation showed shorter kidney lumpectomy times and less bleeding when surgeons were able to train before the operation on the corresponding 3D printed model. 3D printing therefore represents an innovative tool that would improve patient management prior to partial nephrectomy, through the information it can deliver, but also through surgical simulation.

Evolution of sun-protection measures for children.

BACKGROUND: The prevention of melanoma can be significantly improved by targeting information directly towards the subpopulation of children and, as a means to achieve it, towards young parents. OBJECTIVES: The objective of this analysis was to determine the evolution over time of the sun-protection measures adopted by parents for their young children. METHODS: The Edifice Melanoma survey was based on telephone interviews of a representative sample of 1502 subjects aged ≥18 years. This particular analysis focuses on 864 adults whose children are exposed to the sun for more than 10 days a year. We compared the characteristics and attitudes of two sub-groups of parents with regard to sun protection of young children: current-day behaviour of parents with children <15 years and behaviour in the past of parents whose children are now ≥15 years. RESULTS: Present-day parents are more likely than those of previous generations to systematically or often use hats (96% vs. 90%, P < 0.01), protective clothes (92% vs. 84%, P < 0.01), sunscreen (89% vs. 80%, P < 0.01) and sunglasses (63% vs. 44%, P < 0.01) for their children. Systematic application of sunscreen is also more frequent today than several years ago as reported by 81% of present-day parents vs. 74% of those in the past (P < 0.05). Cream is reapplied every 2 h by 41% of present-day parents, compared to 33%, in the past (P < 0.05). CONCLUSIONS: The attitude of parents towards sun protection for their children has improved over the past decade.

Personal vs. intrinsic melanoma risk awareness: results of the EDIFICE Melanoma survey.

BACKGROUND: The efficiency of skin cancer prevention programmes is strongly correlated with the information dispensed, and with the level of risk awareness, of the overall population on one hand, and on the other, of specific sub-populations, according to their risk profiles. OBJECTIVES: The primary objective of this analysis was to establish a correlation between individual perceptions of the risk of developing a melanoma, and the recognized intrinsic risk factors for a given individual. Secondary objectives were to assess factors that are potentially associated with acceptable, high or low perception of melanoma risk. METHODS: The EDIFICE Melanoma survey was conducted in 2011 via telephone interviews of a representative sample of 1502 individuals aged 18 and older in the French population. RESULTS: Although most respondents (73%) had a true estimation of their intrinsic risk for melanoma, those who did not (underestimation, 17%; overestimation, 10%) had an attitude towards environmental risk factors (sun exposure, sun protection, sunbed use) that did not compensate for this misplaced perception. CONCLUSIONS: Skin cancer prevention messages need to be reinforced, new methods of evaluating understanding of the messages need to be implemented, and both need to be included into personal risk assessment.

Alcohol intake modulates the effect of a polymorphism of the cholesteryl ester transfer protein gene on plasma high density lipoprotein and the risk of myocardial infarction.

A polymorphism of the CETP gene (CETP/TaqIB) with two alleles B1 (60%) and B2 (40%) has been investigated in relation to lipid variables and the risk of myocardial infarction in a large case-control study (ECTIM) of men aged 25-64. No association was observed between the polymorphism and LDL or VLDL related lipid variables. Conversely, B2 carriers had reduced levels of plasma CETP (P < 0.0001) and increased levels of HDL cholesterol (P < 0.0001) and of other HDL related lipid variables. The effects of the polymorphism on plasma CETP and HDL cholesterol were independent, suggesting the presence of at least two functional variants linked to B2. A search for these variants on the coding sequence of the CETP gene failed to identify them. The effect of B2 on plasma HDL cholesterol was absent in subjects drinking < 25 grams/d of alcohol but increased commensurably, with higher values of alcohol consumption (interaction: P < 0.0001). A similar interaction was not observed for plasma CETP. The odds-ratio for myocardial infarction of B2 homozygotes decreased from 1.0 in nondrinkers to 0.34 in those drinking 75 grams/d or more. These results provide the first demonstration of a gene-environment interaction affecting HDL cholesterol levels and coronary heart disease risk.

Angiotensinogen gene polymorphisms in IDDM patients with diabetic nephropathy.

Genotypic abnormalities of the renin-ANG system have been suggested as a risk factor for the development of diabetic nephropathy. Cleavage of angiotensinogen is the rate-limiting step in the activation of the renin-ANG system. The TT genotype of a polymorphism encoding threonine instead of methionine (M235T) has been associated not only with increased plasma angiotensinogen concentration but also with essential hypertension. In addition, a polymorphism in the angiotensinogen gene substituting methionine for threonine (T174M) has been associated with hypertension in nondiabetic populations. We studied the relationship between these polymorphisms in the angiotensinogen gene in IDDM patients with diabetic nephropathy (121 men, 74 women, age 40.9 +/- 10 years, diabetes duration 27 +/- 8 years). There was no difference in M235T genotype distribution between IDDM patients with diabetic nephropathy and those with normoalbuminuria: 73/97/25 (37/50/13%) vs. 67/95/23 (36/52/12%) had MM/MT/TT genotypes, respectively. No difference in distribution of T174M genotypes between nephropathic and normoalbuminuric IDDM patients was observed either: 148/44/1 (77/23/0.5%) vs. 141/42/2 (76/23/1%) had TT/TM/MM genotypes, respectively. In patients with nephropathy, systolic blood pressure was higher (161 +/- 22 mmHg [mean +/- SD]) in patients carrying TT genotype of the M235T angiotensinogen polymorphism as compared with patients with MM or MT genotypes (150 +/- 23 mmHg; P = 0.03). We conclude that neither the M235T nor the T174M polymorphism in the angiotensinogen gene contributes to genetic susceptibility to diabetic nephropathy in white IDDM patients, whereas the TT genotype of the M235T is associated with elevated blood pressure in patients with diabetic nephropathy.

Polymorphisms in the genes encoding platelet-derived growth factor A and alpha receptor.

Platelet-derived growth factors (PDGFs) may play an important role in the development of atherosclerosis acting as chemoattractants and mitogens for vascular smooth muscle cells and macrophages. Three dimeric forms of PDGF (AA, AB, BB) have different activities due to distinct binding properties mediated by two types of PDGF receptors (Ralpha, Rbeta). To investigate the possible contribution of molecular variants in the human PDGF-A and PDGF-Ralpha genes to coronary heart disease we screened these genes for polymorphisms by polymerase chain reaction/single-strand conformation polymorphism analysis. A total of 600 men with myocardial infarction and 717 age-matched male controls from four populations in Northern Ireland and France (the ECTIM Study) were gneotyped for newly identified polymorphisms in the genes encoding PDGF-A (C-26IN3T, H69H, C+12IN5T) and PDGF-Ralpha [-1630 I/D (+/-AACTT), A-1506G, C-1390G, G-956A, C-908A, G-793T, +69 I/D (+/-GA)] using allele-specific oligonucleotides. All PDGF-Ralpha polymorphisms, except C-908A, involving a nucleotide change in a common consensus site for GCF and SP-1 transcription factors, were in nearly complete association, generating two major haplotypes. The PDGF-A and PDGF-Ralpha polymorphisms provided a heterozygosity of 0.69 and 0.40, respectively. Genotype and allele frequencies of the PDGF-A and PDGF-Ralpha polymorphisms did not differ between patients with myocardial infarction and controls in either country. None of the polymorphisms investigated was associated with blood pressure, coronary artery stenosis, or any biochemical parameter available in the ECTIM Study.

[Blood pressure control in hypertensive patients with stable coronary heart disease]. / Contrôle de la pression artérielle chez l'hypertendu coronarien stable.

OBJECTIVE: To evaluate systolic blood pressure (SBP) control in hypertensive patients with a stable coronary heart disease (CHD) in general practice in France. METHODS: A survey was conducted in a sample of 206 general practitionners (GP) representative of the French medical population, in 2003 [LHYCORNE survey]. Each GP had to include 3 hypertensive patients, >18 years old, BP > or = 140/90 mmHg and/or treated for hypertension, and with evidence of CHD documented by myocardial infarction (MI) or angina pectoris (AP) [diagnosis previously established by a cardiologist]. Three office BP measurements were performed, the last two recorded. BP levels were considered as controlled by treatement if they were < 140/90 mmHg. RESULTS: 595 patients were included, 75% men mean age 66 years, 25% women mean age 73 years. All patients had a CHD: MI 46%, AP 54%; 533 (90%) had more than 2 cardiovascular risk factors: hyperlipidemia (411; 69%), smokers (375; 63%), diabetes (158; 27%). Mean BP was 140.7 +/- 14/80.8 +/- 9.7 mmHg; 553 (93%) of these hypertensive patients were treated, and 239 (40%) were considered as having a controlled SBP at the treshold of 140 mmHg: 47% in patients with previous MI and 38% with AP (p < 0.001). Diastolic BP (DBP) was <90 mmHg in 480 (81%) and pulse pressure was >65 mmHg in 202 (34%); 313 (53%) patients received a combination of three drugs or more; 354 (60%) had a beta-blocker, 260 (44%) a calcium channel blocker, 237 (40%) an ACE inhibitor, 287 (48%) other antihypertensive drugs (246 diuretics, 41%); 502 (84%) received antiplatelet therapy, 403 (68%) statins. CONCLUSION: This survey shows that systolic BP is not at goal in 6/10 hypertensive patients with stable CHD suggesting there is a place for a more effective combination therapy according to evidence-based medicine.

Influence of angiotensin II type 1 receptor polymorphism on aortic stiffness in never-treated hypertensive patients.

Several clinical and experimental studies have suggested a significant role of angiotensin II in the development of alterations of small and large arteries. The present study was designed to assess the contribution of polymorphism (corresponding to an A1166-->C transversion) of the angiotensin II type 1 receptor (AT1) gene to aortic stiffness. One hundred thirty-four never-treated hypertensive patients were included in the study. Aortic distensibility was evaluated by measuring carotid-femoral pulse wave velocity. Age, systolic and diastolic pressure, and metabolic parameters were similar in the three genotypes. Pulse wave velocity was 11.4 +/- 2.5 m/s in AT1 AA homozygotes, 12.5 +/- 3.2 m/s in AC heterozygotes, and 14.7 +/- 4.0 m/s in CC homozygotes (P = .003, P < .001 after adjustment for age, blood pressure, and body mass index). Moreover, an interaction was found between AT1 genotype and the ratio of total to high-density lipoprotein cholesterol in terms of the development of aortic stiffness. Thus, a positive correlation was observed between the ratio of total to high-density lipoprotein cholesterol and pulse wave velocity in AC and CC (r = .42, P < .001) but not AA patients. These results suggest that the AT1 gene is involved in the development of aortic stiffness in hypertensive patients and could modulate the effects of lipids on large arteries.

Polymorphisms of the transforming growth factor-beta 1 gene in relation to myocardial infarction and blood pressure. The Etude Cas-Témoin de l'Infarctus du Myocarde (ECTIM) Study.

Transforming growth factor-beta 1 (TGF-beta 1) plays an important role in the modulation of cellular growth and differentiation and the production and degradation of the extracellular matrix. A number of experimental results suggest that TGF-beta 1 may be involved in cardiovascular physiopathology. In the present study, we assessed whether the TGF-beta 1 gene is a candidate gene for coronary heart disease or hypertension. We screened the coding region and 2181 bp upstream of the TGF-beta gene for polymorphisms and identified seven polymorphisms: 3 in the upstream region of the gene at positions -988, -800, and -509 from the first transcribed nucleotide; 1 in a nontranslated region at position +72; 2 in the signal peptide sequence Leu10-->Pro, Arg25-->Pro; and 1 in the region of the gene coding for the precursor part of the protein not present in the active form, Thr263-->Ile. We analyzed these TGF-beta 1 polymorphisms in 563 patients with myocardial infarction and 629 control subjects from four regions in Northern Ireland and France. The Pro25 allele was more frequent in patients than in control subjects in Belfast (P < .01) and Strasbourg (P < .05). The TGF-beta 1 polymorphisms were not associated with the degree of angiographically assessed coronary artery disease in patients. The presence of a Pro25 allele was associated with a lower systolic pressure in the four control groups (P < .002), and a history of hypertension was significantly less frequent in homozygotes or heterozygotes for Pro25 than in hormozygotes for Arg25 (odds ratio, 0.43, 95% confidence interval, 0.19 to 0.92; P < .03). Since the Pro25 allele was associated with an increased risk of myocardial infarction and a reduced risk of hypertension, we favor a cautious interpretation of these apparently inconsistent results. Other studies will need to verify whether these associations are real.

Influence of the angiotensin II type 1 receptor gene polymorphism on the effects of perindopril and nitrendipine on arterial stiffness in hypertensive individuals.

Angiotensin-converting enzyme inhibitors improve arterial stiffness independently of blood pressure reduction. Since we have recently shown that in hypertensive individuals the A1166C polymorphism of the angiotensin II type 1 receptor (AT1-R) is an independent determinant of aortic stiffness, we designed the present study to assess the influence of this polymorphism on the changes of aortic stiffness after chronic treatment with the angiotensin-converting enzyme inhibitor perindopril and the calcium channel blocker nitrendipine. Forty perindopril- and 42 nitrendipine-treated hypertensive individuals were studied. We evaluated aortic stiffness by measuring the carotid-femoral pulse wave velocity. Carriers of the AT1-RC allele showed higher baseline values of pulse wave velocity than AA homozygotes (P < .05). In the perindopril group, a threefold greater reduction in pulse wave velocity was observed in carriers of the C allele than in AA homozygotes (-2.85 +/- 0.62 versus -0.94 +/- 0.32 m/s, respectively; P < .001), whereas in the nitrendipine group, pulse wave velocity decreased only in AA homozygotes and not in AT1-R C carriers (-1.38 +/- 0.35 versus +0.04 +/- 0.60 m/s, respectively; P < .01). These results indicate that according to the AT1-R A1166C genotype, an angiotensin-converting enzyme inhibitor and a calcium channel blocker affect pulse wave velocity in opposite ways. Since some evidence shows that increased pulse wave velocity may enhance cardiovascular risk, it might be useful for physicians to consider the AT1-R genotype when prescribing an angiotensin-converting enzyme inhibitor or calcium channel blocker to a hypertensive individual.

Genetic variation at the angiotensinogen locus in relation to high blood pressure and myocardial infarction: the ECTIM Study.

OBJECTIVES: To study the association between polymorphisms of the angiotensinogen (AGT) gene and blood pressure in population-based samples, and to determine whether genetic variation at the AGT locus is involved in the susceptibility to myocardial infarction. METHODS: The study population comprised 630 cases who survived a myocardial infarction, recruited from the World Health Organization Monitoring Cardiovascular Diseases registers in Belfast, Lille, Strasbourg and Toulouse, and 741 controls drawn from the corresponding populations. The AGT polymorphisms investigated were T174M and M235T. High blood pressure was defined as diastolic blood pressure > 100 mmHg or the use of antihypertensive medication, or both. RESULTS: In the controls the mean +/- SEM frequency of the M174 allele was 0.116 +/- 0.008, and that of the T235 allele was 0.401 +/- 0.013. In the whole population blood pressure levels and prevalence of high blood pressure did not vary according to T174M and M235T genotypes. However, obesity appeared as a crucial factor influencing the relationship between high blood pressure and T174M. In subjects with body mass index < 26 kg/m2 there was a 2.4-fold increase of the prevalence of high blood pressure in carriers of the M174 allele compared with in homozygotes for the T174 allele, whereas no association was detected in subjects with body mass index > 26 kg/m2. The association between high blood pressure and M235T was not significant in either group. The T174M and M235T genotype distributions did not differ between survivors of myocardial infarction and controls. CONCLUSIONS: These data suggest that the AGT gene could be involved in the predisposition to high blood pressure in non-overweight, but not in overweight men, possibly reflecting genetically different types of hypertension. No significant impact of the AGT locus in the risk of non-fatal myocardial infarction was detected.

New polymorphisms of the angiotensin II type 1 receptor gene and their associations with myocardial infarction and blood pressure: the ECTIM study. Etude Cas-Témoin de l'Infarctus du Myocarde.

OBJECTIVE: In an earlier report, we suggested that a polymorphism located in the 3' untranslated region of the angiotensin II type 1 receptor gene (AT1R+1166 A/C) might interact with the angiotensin I converting enzyme (ACE) insertion/deletion (I/D) polymorphism to increase the risk of myocardial infarction. Since the AT1R+1166 A/C polymorphism does not appear to be functional, we postulated that it might be in linkage disequilibrium with an unidentified functional variant which would affect the regulation of the gene in response to angiotensin II. The present study was conducted to identify new polymorphisms of the AT1R gene that might be responsible for this interaction. METHODS: The first four exons, which are untranslated, and 2.2 kb in the 5' flanking region of the AT1R gene were explored by polymerase chain reaction/single-strand conformation polymorphism. Seven polymorphisms were detected in the 5' region at positions -1424, -810, -713, -521, -214, -213 and -153 upstream from the start of transcription. The genotypes of the -810, -713, -214, -213 and -153 polymorphisms were completely concordant. One substitution was detected at the 55th nucleotide of exon 4. These polymorphisms, together with the +1166 A/C polymorphism and a previously described T/C substitution at the 573th nucleotide of exon 5, were genotyped in the Etude Cas-Témoin de l'Infarctus du Myocarde (ECTIM) study, a multicentre study comparing 651 patients who had survived a myocardial infarction and 728 controls from Belfast (United Kingdom) and Lille, Strasbourg and Toulouse (France). RESULTS: The newly identified polymorphisms were not in linkage disequilibrium with the +1166 A/C polymorphism and therefore could not explain the interaction observed with ACE I/D. None of the polymorphisms was associated with blood pressure levels in control subjects. In the four populations, the A allele of the -810 polymorphism was associated with a lower risk of myocardial infarction (population-adjusted odds ratio of 0.80, confidence interval 0.65-0.97, P< 0.05). CONCLUSIONS: None of the newly identified polymorphisms could account for the previously described interaction between the AT1R+1166 A/C and the ACE I/D polymorphisms affecting the risk of myocardial infarction. However, the present study suggests that AT1R-810 T/A, or other polymorphisms which are in complete association with it, might be associated with the risk of myocardial infarction. Further studies are required to confirm this finding and to identify the functional variants.

Performance of physical examination skills in medical students during diagnostic medicine course in a University Hospital of Northwest China.

This study was conducted to evaluate the performance of physical examination (PE) skills during our diagnostic medicine course and analyze the characteristics of the data collected to provide information for practical guidance to improve the quality of teaching. Seventy-two fourth-year medical students were enrolled in the study. All received an assessment of PE skills after receiving a 17-week formal training course and systematic teaching. Their performance was evaluated and recorded in detail using a checklist, which included 5 aspects of PE skills: examination techniques, communication and care skills, content items, appropriateness of examination sequence, and time taken. Error frequency and type were designated as the assessment parameters in the survey. The results showed that the distribution and the percentage in examination errors between male and female students and among the different body parts examined were significantly different (p<0.001). The average error frequency per student in females (0.875) was lower than in males (1.375) although the difference was not statistically significant (p = 0.167). The average error frequency per student in cardiac (1.267) and pulmonary (1.389) examinations was higher than in abdominal (0.867) and head, neck and nervous system examinations (0.917). Female students had a lower average error frequency than males in cardiac examinations (p = 0.041). Additionally, error in examination techniques was the highest type of error among the 5 aspects of PE skills irrespective of participant gender and assessment content (p<0.001). These data suggest that PE skills in cardiac and pulmonary examinations and examination techniques may be included in the main focus of improving the teaching of diagnostics in these medical students.

Variations in the APP gene promoter region and risk of Alzheimer disease.

We genotyped five polymorphisms, including two polymorphisms with known effects on transcriptional activity, in a large cohort of 427 Alzheimer disease (AD) cases and 472 control subjects. An association between rs463946 (-3102 G/C) and AD was found and was confirmed in a replication sample of a similar size. By contrast, analysis of three recently described rare mutations influencing APP transcription did not confirm their association with AD risk.

New developments in renal physiopathology acquired using a quantitative renal functional test: the 197Hg uptake test.

The renal function of 331 obstructive uropathies, of which 112 were unilateral, were studied using the radioactive Hg renal uptake technique. The results obtained lead to the following observations: (1) Kidneys silent because of a chronic pelviureteric obstruction maintain a minimum function representing approximately one quarter of the normal value, which does not seem to be improved following the removal of the obstruction. (2) Operative relief of obstruction in unilateral obstructive uropathy, except for cases of silent kidneys, is followed by a significative improvement in the function of the kidney on the operated side in more than a third of the cases studied. (3) In 43% of obstructive uropathies considered as unilateral, the functional value of the two kidneys is decreased.

Radioruthenium -- 2,3-Dimercaptopropansulfonic acid complex. A potentially useful radiocompound for kidney studies.

Radioruthenium complexed with 2,3-dimercaptopropansulfonic acid (DMPSA) shows a preferential localization in kidneys. After studying several parameters with regard to their influence on renal incorporation, the optimal procedure was established, showing an uptake by kidney (for 97Ru-labelled compound) of 30.3% dose/g/24 h or 43.4% dose/organ/24 h. The highest accumulation was reached 7-10 h after iv injection and no significant elimination was observed 24 h thereafter. The probable mechanisms involved in this process are discussed.

[Adolescents' fear of dental treatment: development and evaluation of a cognitive inventory]. / La peur des traitements dentaires chez les jeunes adolescents: développement et évaluation d'une mesure cognitive.

Morin et al.'s Inventaire cognitif de la peur des traitements dentaires pour adolescent(e)s [Adolescents' Fear of Dental Treatment Cognitive Inventory] was administered to 343 subjects. Factor analysis revealed a single general factor that accounted for 33.5 per cent of the total variance. A reliability test revealed an alpha coefficient of 0.91, which was quite acceptable. A measure of test-retest reliability over a four-week period (N = 181) indicated that the scale was stable over time (r = 0.85). Standard error of measurement was found to be 4.63. Normative data are provided along with a description of the final version of the scale.
