The Mean

The Estonian NEO‐FFI was administered to 2650 Estonian adolescents (1420 girls and 1230 boys) aged from 12 to 18 years and attending 6th, 8th, 10th, or 12th grade at secondary schools all over Estonia. Although the mean levels of personality traits of Estonian adolescents were quite similar to the respective scores of Estonian adults, there was a developmental gap in Agreeableness and Conscientiousness. Three of the five personality dispositions demonstrated a modest cross‐sectional change in the mean level of the trait scores: the level of Openness increased and the levels of Agreeableness and Conscientiousness decreased between 12 and 18 years of age. Although the five‐factor structure of personality was already recognizable in the sample of 12‐year‐old children, it demonstrated only an approximate congruence with the adult structure, suggesting that not all children of that age have developed abilities required for observing one's own personality dispositions and for giving reliable self‐reports on the basis of these observations. The self‐reported personality trait structure matures and becomes sufficiently differentiated around age 14–15 and grows to be practically indistinguishable from adult personality by the age of 16. Personality of adolescents becomes more differentiated with age: along with the growth of mental capacities the correlations among the personality traits and intelligence become smaller.

Age differences in personality traits can inform us on the magnitude and qualities of personality development and describing them accurately is therefore of utmost importance. Little research yet has examined age differences by combining more than one source of information, despite many psychologists knowing that any one assessment method is prone to artefacts. We compared age differences in a range of personality traits such as Five-Factor Model (FFM) facets and nuances in self-reports and ratings by knowledgeable informants. Relying on samples from three countries (total N = 5,624) allowed us to cross-validate and meta-analyze the findings. We hypothesized that age differences would be larger in self-reports, because socially desirable responding increases with age. Indeed, we found that age-differences were systematically smaller in informant-reported facets and nuances compared to their self-reported counterparts and that this trend was stronger for traits independently rated as socially desirable. These findings replicated across multiple samples. We also hypothesized that variance of self-reported traits would decrease with age for evaluative traits, but this hypothesis received inconsistent support. We conclude that age differences may be inflated in self-reports partly because of socially desirable responding. However, since we cannot definitively rule out that age differences are underestimated in informant-ratings, they may be best approximated by average trends of self- and informant-reports. We therefore provide meta-analytic age trends for multi-rater composite scores of the FFM traits, their facets, and items. This is among the most rigorous studies yet into cross-sectional age differences in personality traits.

Chapter 2 reviews research and theory on the life story and its development and relations to other aspects of personality. The authors introduce the integrative framework of McAdams and Pals, who described three levels in a broad model of personality: personality traits; personal goals, values, and projects; and the unique life story, which provides a degree of unity and purpose to the individual’s life. This narrative, which develops in late adolescence and emerging adulthood, as individuals become able to author their own stories, includes key scenes of emotional and personal importance to provide a sense of continuity, while remaining flexible and dynamic in incorporating changes in the self over time. The chapter ends with a description of Alison, an emerging adult from our Canadian Futures Study, who illustrates these levels and what they tell about personality development during this period.

Blind Spots

Despite the strong intuition that people know themselves well, much research in self-perception demonstrates the biases present when evaluating one’s own personality traits. What specifically are these blind spots in self-perceptions? Are self-perceptions always disconnected from reality? And under what circumstances might other people actually be more accurate about the self? The self–other knowledge asymmetry (SOKA) model suggests that because individuals and others differ in their susceptibility to biases or motivations and in the information they have access to, self- and other-knowledge will vary by trait. The present chapter outlines when and why other-perceptions are sometimes more accurate than self-perceptions, as well as when self-reports can be most trusted. Also discussed are next steps in the study of self- and other-knowledge, including practical, methodological, and interdisciplinary considerations and extensions. In sum, this chapter illustrates the importance of taking multiple perspectives in order to accurately understand a person.

Objectives: To investigate and compare the extent of shared decision making (SDM) in orthodontics from the perspective of patients, clinicians and independent observers. Design: A cross-sectional, observational study. Setting: NHS teaching hospital. Participants: A total of 31 adult patients and their treating clinicians were included in the study. Methods: The extent of SDM in new patient orthodontic consultations was measured using three versions of a validated instrument: the self-administered patient dyadic-OPTION scale; the self-administered clinician dyadic-OPTION scale; and an independent observer-rated OPTION12 scale. Patients and clinicians completed the 12-item dyadic-OPTION questionnaire independently at the end of the consultation to rate their perceived levels of SDM. The consultations were also audio-recorded and two calibrated raters independently rated the extent of SDM in these consultations using the OPTION12 scale. Results: There was excellent inter-rater reliability between the two independent raters using the OPTION12 scale (intraclass correlation coefficient (ICC) = 0.909). The mean patient, clinician and independent observer OPTION scores for SDM were 90.4% (SD 9.1%, range 70.8% to 100%), 76.2% (SD 8.95%, range 62.5% to 95.8%) and 42.6% (SD 17.4%, range 13.5% to 68.8%), respectively. There was no significant correlation between the OPTION scores for the three groups (ICC = −0.323). Conclusions: The results showed that generally high levels of SDM were perceived by patients and clinicians but lower levels of SDM were scored by the independent observers. However, it could be argued that the patient’s perception of SDM is the most important measure as it is their care that is affected by their involvement.

Background: Diabetes is a global epidemic with serious complication and there is a clear need for paying special attention to self-management as the cornerstone to optimal control of the disease. Objectives: This study aimed to assess the self-management status and its correlation to disease control indicators in people with diabetes. Methods: In a descriptive cross-sectional study, 220 patients were selected from the list of the referred patients available in Lamerd public health network from December 2014 to June 2015. In the first step, data about demographic information and disease control were collected from the patients’ records. In the second step, the self-management status of each patient was assessed by the Diabetes Self-Management Questionnaire developed by Schmitt et al. To analyze the data, independent sample t-test and Pearson correlation coefficient were used. Results: The mean age of the male and female participants was 56.43 ± 13.50 and 56.46 ± 10.49 years old, respectively. The mean duration of the disease was 6.67 ± 4.72 years for men and 7.07 ± 5.30 years for women. Twenty-one (25.9%) men and 60 (43.7%) women had a history of smoking. The results of the Pearson correlation coefficient showed that there was an inverse and statistically significant relationship between diabetes self-management status and weight, body mass index (BMI), waist circumference, glucose tolerance test (GTT), LDL, and cholesterol. The results of the t-test did not show significant differences between the level of HbA1C (HbA1C7) and self-management scores of the patients (P > 0.05). Conclusions: Patients with better self-management status were in a better disease control condition with respect to weight, BMI, waist circumference, GTT, LDL, and cholesterol levels. Special attention to the control and management of LDL, cholesterol, HbA1C, BMI, and blood pressure levels is recommended in planning for these patients.

This research investigates the associations of psychological and biological factors with the self-perceived health of old persons. Participants were 411 residents of 11 retirement homes in Zagreb, Croatia: 104 men, 307 women, aged 56–96 years (average 79) at baseline, mobile, and not diagnosed with dementia. The variables measured, at baseline and at 2-year follow-up, were sociodemographics, self-perceived health, functional ability, cognitive function, depression, and social participation. Biochemical variables were measured from vein blood sample at baseline. Cross-sectional and longitudinal analyses explained 33%–38% of self-perceived health variance. Functional ability, depressive symptoms, and age were significant predictors of self-perceived health in all analyses. Two biological cardiovascular risk factors variables – glucose and urea – were significantly associated with self-perceived health.

Chart Recording

Acoustic measurements of the distance between the water surface, top of the aquatic plants, and bottom of the water column were made using chart recording echosounders. The vertical cross sectional area (m2), height (m), biovolume (m3), of aquatic plant beds and variances were computed for three surveys of Devils Lake, Oregon, in May, July, and September, 1986 when coefficients of variation for the plant bed biovolume estimates were 0.18, 0.05, and 0.06, respectively (n = 14). Coefficients of variation for plant biomass estimates (g/m2) computed from SCUBA quadrat samples collected concurrently with the acoustic surveys, were 0.98 (n = 48), 0.81 (n = 90), and 1.05 (n = 90), respectively. The higher precision of the biovolume estimates allow for a 5- to 18-fold greater capability to detect a change in the mean. The lower costs of the biovolume estimates allow for a 10- to 33-fold greater precision-for-cost. The plant bed biovolume variable contains ecologically different information than the biomass variable in that it provides a direct estimate of the amount of aquatic habitat in a lake that is influenced by plants; it should prove useful for evaluating plant control practices and possibly for studying plant-fish interactions.

Risk Of Aspiration

• Background Oral care and head-of-bed elevation are interventions to decrease risk of aspiration pneumonia in hospitalized patients. In a previous study, nurses’ self-reports of how often they performed oral care did not match documented provision of such care. • Objectives To replicate the original study and estimate instrument reliability. • Methods A cross-sectional design was used, and survey data from nursing personnel and bedside observational data from 9 intensive care units were collected. • Results A total of 181 surveys (47%) were returned, and data were collected from 436 bedsides. Reported frequencies of oral care and use of oral care products differed between nonintubated and intubated patients (P<.001). The mean documented frequency of oral care for nonintubated patients was 1.8 (SD 1.5); self-reported frequency was 3 (SD 2.4). The mean documented frequency of oral care for intubated patients was 3.3 (SD 1.8); self-reported frequency was 4.2 (SD 2.1). Documented oral care frequency differed by unit (P = .006) and intubation status (P < .001). Mean observed head-of-bed position was 38° (SD 24°) for nonintubated patients and 23° (SD 12°) for intubated patients (P < .001). Intubation status, but not unit, affected observed head-of-bed position (P < .001). Three survey items had adequate reliability evidence (r=0.70). Interrater reliability for bedside data collection was 96% or greater. • Conclusions Despite inadequate estimates of survey reliability, findings generally were comparable to results of the original study; nurses report more frequent oral care than is documented. Intensive care nurses elevate the head of patients’ beds in accordance with self-reports.

AbstractThe genetic and environmental etiology of individual differences was examined in initial level and change in psychopathic personality from ages 9 to 18 years. A piecewise growth curve model, in which the first change score (G1) influenced all ages (9–10, 11–13, 14–15, and 16–18 years) and the second change score (G2) only influenced ages 14–15 and 16–18 years, fit the data better did than the standard single slope model, suggesting a turning point from childhood to adolescence. The results indicated that variations in levels and both change scores were mainly due to genetic (A) and nonshared environmental (E) influences (i.e., AE structure for G0, G1, and G2). No sex differences were found except on the mean values of level and change scores. Based on caregiver ratings, about 81% of variance in G0, 89% of variance in G1, and 94% of variance in G2were explained by genetic factors, whereas for youth self-reports, these three proportions were 94%, 71%, and 66%, respectively. The larger contribution of genetic variance and covariance in caregiver ratings than in youth self-reports may suggest that caregivers considered the changes in their children to be more similar as compared to how the children viewed themselves.

ABSTRACT Objective: To evaluate the level of self-referenced treatment adherence (TA) and its association with clinical and sociodemographic variables in patients with cystic fibrosis assisted at a reference center, as well as compare the level of self-referenced TA with that presumed by the multidisciplinary team. Methods: This is a cross-sectional study that included children and adolescents aged between 0-20 years with cystic fibrosis. Adolescents older than 14 years or their guardians, when younger than 14 years old, were interviewed using a standardized questionnaire. Professionals from the multidisciplinary clinic filled out another form with their impressions of the patients’ TA. Clinical and laboratory data were obtained in the medical records. The TA was considered satisfactory if the total adherence index (TAI) was equal or higher than 80%. Results: 53 patients were included with a median age of 112 months. The mean TAI was 83.2%. The mean TAIs for dornase alfa, pancreatic enzymes, continued use of inhaled tobramycin, vitamins supplements, nutritional supplements and dietary orientation was respectively: 86.1; 96.6; 78.6; 88.1; 51.8 and 78%. Children younger than 14 years presented better TA (p=0.021). The correlation between the self-referenced TA and the one presumed by the multidisciplinary team ranged from 0,117 to 0.402, being higher for Psychology and Nutrition professionals. Conclusions: The TAI was high particularly among children younger than 14 years. There was a positive correlation between the self-referenced TA and the one presumed by the Psychology (p=0.032) and the nutrition (p=0.012) professionals.
