Restlessness and psychomotor agitation after kidney transplantation: their impact on perceived health status

Restlessness and psychomotor agitation are among the causes of morbidity and mortality in different diseases. They are known problems in end-stage renal disease patients but no study has ever evaluated their presence and effects in kidney recipients. This study aimed to explore the presence of restlessness and psychomotor agitation and their relation with morbidity of patients after renal transplantation. Sixty-one subjects were randomly selected from kidney transplant recipients being followed in Baqiyatallah Hospital, Tehran, Iran. Restlessness and psychomotor agitation were determined by Hospital Anxiety and Depression Scale (HADS). The correlation of these scores with demographic data, clinical data, sexual function, marital adjustment, quality of life, sleep quality and medical comorbidity of patients was evaluated. The scores of restlessness and psychomotor agitation were significantly correlated with the age at transplantation (r = .269, p = .04 and r = .324, p = .01, respectively), the total score of medical comorbidity (r = .273, p = .02 and r = .257, p = .04, respectively), role limitation due to emotional problems (r = -.26, p = .03 and r = -.25, p = .04, respectively) and mental health (r = -.277, p = .02 and r = -.252, p = .04 respectively). There was no correlation between these symptoms and the gender, marital status, and sexual relationship score of the patients (p > .05). Restlessness and psychomotor agitation are frequent and can impose high degrees of morbidity on renal transplant recipients. Proper management of these problems seems to improve the different aspects of quality of life in these patients.     

Eating behaviour, body image, and self-esteem of adolescent girls in Malaysia

This cross-sectional study was undertaken with 489 secondary school girls, ages 15-17 years, to examine disordered eating behaviours of adolescent girls in Malaysia and to estimate associations with body weight, body-size discrepancy, and self-esteem. Dietary restraint, binge eating, body image, and self-esteem were assessed using the Restrained Eating scale of the Dutch Eating Behaviour Questionnaire, the Binge Scale Questionnaire, the Contour Drawing Rating Scale, and the Rosenberg Self-Esteem Scale, respectively. Pearson correlations estimated associations between variables. There were 3.1% underweight, 9.8% at risk of being overweight, and 8.6% overweight girls. A total of 87.3% were dissatisfied with their own body size. Dietary restraint and binge eating were reported by 36.0% and 35.4%, respectively. Body Mass Index (r = .34, p < .01) and body-size dissatisfaction (r = .24, p < .01) were significantly associated with dietary restraint and binge eating, but self-esteem (r = -.20, p < .001) was significantly associated only with binge eating.     

Visual analogue scale correlates of musculoskeletal fatigue

Visual analogue scale has been shown to reflect subjective feelings but rarely has it been used for musculoskeletal fatigue so in the present study VAS ratings were used to quantify musculoskeletal fatigue. A total of 20 students underwent a fatigue protocol (M age=21.3 yr., SD= 1.0). A series of randomized external loads at 0, 5, 10, 15, 25, 35, and 50% of the maximum voluntary contraction was generated by the BTE Primus and applied at the distal end of the dominant arm, which was sustained at the 90 degrees forward flexion position. After 60 sec. of force exertion for each loading, the subject marked the scale to reflect their extent of fatigue at the shoulder muscle. Analysis showed fatigue scores were significantly correlated with the percentages of maximum load applied (r =.73, p < or = .01). The correlation between higher external loads (25-50% maximum load) and fatigue scores was .57 (p < or = .01) and that for lower external loads (0-15% maximum load) was .44 (p < or = .01). The validity of using a visual analogue scale as a measure of musculoskeletal fatigue requires further study, particularly for a low load.     

Assessing concrete and abstract thinking with the Draw-a-Person technique

In this study, we examined the Draw-a-Person (DAP) technique as an indicator of concrete/literal and abstract thinking, Subjects (N = 50) included schizophrenic inpatients (n = 25) and college students (n = 25). Fourteen possible indicators of concrete/literal or abstract thinking on the DAP were generated based on theoretical considerations and prior research. Five indicators were eliminated because of their low interrater reliability. The Proverbs Test (Gotham, 1956) was used to establish evidence of concrete/literal and abstract thinking. Scores from the DAP and the Proverbs Test were correlated. Composite scores on the DAP were highly correlated (r = .52, p < .01) with the corresponding Proverbs Test score. In addition, abstract scores on the DAP were correlated (r = .54, p < .01) with a similar Proverbs Test score.. Concrete/literal DAP scores did not correlate significantly (r = .20, p > .05) with concrete/literal Proverb Test scores. Results indicate the potential for using the DAP technique to assess concrete/literal and abstract thinking when a nonverbal test is needed.     

Relationships between mood state, time estimation, and selected movement speed

We investigated whether different aspects of mood state influence sense of time estimation and movement speed. Mood states were measured on the Multiple Mood Scale for 142 female undergraduate students, who were then asked to estimate the interval of time elapsed between the words "start" and "stop" spoken by a tester. Next, the same subjects were told to draw circles inside 1-cm squares printed on an A4 size sheet of paper in succession at their freely elected comfortable speed. Scores on Concentration (r=-.22, p<.01) and Being Startled (r=-.26, p<.01) each correlated significantly and negatively with time estimation, while scores on Boredom (r =.17, p <.05) had a significant positive correlation with movement speed. These results suggest that different aspects of mood state have some association with time estimation and selected movement speed. Values account for small common variance.     

Geographical and political predictors of emotion in the sounds of favorite baby names

The top 5 favorite boys' and girls' names from each state of the USA in 2000 and 2003 were analyzed in terms of the emotional associations of their component sounds and sound pronounceability. These were significantly and variously correlated with a historical factor (year), geographic factors (compass directions), and a political factor (percentage of the popular vote cast for President Bush in 2004). The expected stereotypical sex differences were observed: girls' names were longer, more pleasant, less active, and easier to pronounce (p < .01). It was possible to predict emotional associations and pronounceability (R2 = .27-.48, p < .01) on the basis of historical, geographical, and political variables.     

Emotional intelligence and prosocial behaviors in adolescents

The relationship between emotional intelligence and prosocial behaviors and sex differences in 134 adolescents involved in a 6-wk. training camp run by the military was investigated. They were asked to evaluate themselves on emotional intelligence and randomly chosen peers evaluated them on prosocial behaviors, indicated by organizational citizenship behaviors, a measure used in work organizations. Ratings of emotional intelligence significantly correlated with scores on two of the five organizational citizenship behavior factors: Altruism (r = .25, p < .01) and Civic virtue (r = .24, p < .01). The girls scored somewhat, but not significantly, higher than the boys on Emotional Intelligence, Altruism, Conscientiousness, and Civic virtue, an observation which might be explored further.     

Factors in adolescent rebellious feelings.

To verify the existence and determine some sources of 15- and 16-year-old youths' (midteens') antisocial feelings, 174 midteens (89 males and 85 females) from two small Tennessee towns were administered L. Srole's Anomia Scale and two author-devised tests, the Inventory of Midteen Rearing Theories and the Rebellion Scale. As their parents' levels of education rose, midteens' feelings of anomie and rebellion decreased significantly: fathers F (3, 160) = 4.77,p less than .01; mothers F (3, 163) = 2.77, p less than .05. Midteen feelings of anomie and rebellion correlated positively with midteen perception of parent-midteen disagreement about how the midteen should be reared: Anomia r (172) = .25, p less than .01; Rebellion r (172) = .37, p less than .01. Probable causes of extremely rebellious feelings in midteens include parent-midteen conflict over how the midteen should be reared and the midteen's rejection of attending school as a worthwhile occupation.

In addition, abstract scores on the DAP were correlated (r = .54, p < .01) with a similar Proverbs Test score.. Concrete/literal DAP scores did not correlate significantly (r = .20, p > .05) with concrete/literal Proverb Test scores. Results indicate the potential for using the DAP technique to assess concrete/literal and abstract thinking when a nonverbal test is needed.     

The relationship between contrast sensitivity, gait, and reading speed in Parkinson's disease

Parkinson's disease (PD) results in reduced walking speed and visual difficulties, including difficulty reading (Davidsdottir, Cronin-Golomb, & Lee, 2005). PD is characterized by a reduction in dopamine, which is instrumental in determining a person's contrast sensitivity (CS). This study assessed the relationship between CS, gait (step length and walking speed), and reading speed in 18 non-demented PD volunteers with normal acuity. We found that CS correlated with walking speed (r = .57, p = .01), step length (r = .53, p = .02), and reading speed (r = .54, p = .02). Visual acuity (which has not been tied to dopamine in the same way) correlated with reading speed (r(s) = -.65, p = .004), but not with gait measures. We also assessed the contribution of age, education, and cognitive status (Shipley Institute of Living Scale) to these variables. We conclude that CS and age both play an important role in determining gait in PD, while reading speed is related to both acuity and CS, but not age.     

The Relationship Between the WISC-III and the Kaufman Brief Intelligence Test with Students Referred for Gifted Evaluation

A tolal of 29 students (mean age = 7.96 yrs) who were referred for gifted evaluation in an affluent suburban school district in Western Pennsylvania were administered the Kaufman Brief Intelligence Test (K-BIT) and the WISC-III. Paired t-tests comparing the K-BIT mean IQ (120.59) with the WISC-III Verbal (123.65), Performance (118.86) and Full Scale (122.86) IQs yielded no statistically significant differences (t (28) = 1.49, p = .15; t(28) = -0.74, p = .47; t(28) = 1.35, p = .19, respectively). Correlational analyses indicated that the K-BIT and WISC-III Verbal (r = .35. p < .05), Performance (f = .35, p < .05), and Full Scale IQs (r = 53, p < .01) correlated significantly. The limitations and implications of the study are discussed.     

Variability among Deese-Roediger-McDermott lists in eliciting false recall for people's names

According to previous research, the variability of lists in eliciting false recall in the Deese-Roediger-McDermott (DRM) paradigm is large. A list structure made by Mukai, in which people's names were used as critical lures, was used to investigate the variability of lists. The materials were composed of 6 pairs of lists, in which the critical lure and its contextually associated study item (referred to as critical presented item) were assumed to play an important role in eliciting false recall. 80 participants (M age = 21.7 yr.; SD = 2.6) were tested. The difference of the list pair in eliciting false recall was positively correlated with list pair differences in free association rate from critical presented item to critical lure (r = .82, p < .05) and negatively correlated with the length of critical lure (r = -.94, p <.01). It was shown that the variability of lists in eliciting false recall can be explained by these two factors. Moreover, the length of the lure was also negatively correlated with an index of unsuccessful source monitoring (r = -.87, p < .05). The results were discussed in terms of the activation/monitoring theory.     

Uncoupled leftward asymmetries for planum morphology and functional language processing

Explanations for left hemisphere language laterality have often focused on hemispheric structural asymmetry of the planum temporale. We examined the association between an index of language laterality and brain morphology in 99 normal adults whose degree of laterality was established using a functional MRI single-word comprehension task. The index of language laterality was derived from the difference in volume of activation between the left and right hemispheres. Planum temporale and brain volume measures were made using structural MRI scans, blind to the functional data. Although both planum temporale asymmetry (t(1,99) = 6.86, p < .001) and language laterality (t(1,99) = 15.26, p < .001) were significantly left hemisphere biased, there was not a significant association between these variables (r(99) = .01,ns). Brain volume, a control variable for the planum temporale analyses, was related to language laterality in a multiple regression (beta = -.30, t = -2.25, p < .05). Individuals with small brains were more likely to demonstrate strong left hemisphere language laterality. These results suggest that language laterality is a multidimensional construct with complex neurological origins.     

An exploratory study of the facets of Type A personality and scores on the Machiavellian Behavior (MACH-B) Scale

The relationship of two facets of Type A personality, Achievement Striving and Impatience-Irritability, with Mach-B scores was investigated. Mach-B scores were not correlated with Achievement Striving and were positively correlated (r = .37; p < .01) with Impatience-Irritability in a sample of 51 hospital employees including physicians (n = 12), nurses (n = 12), administrative staff (n = 13), and custodial services employees (n = 14).     

Sensitivity to disgust, stigma, and adjustment to life with a colostomy

We examined whether trait disgust sensitivity predicts well-being in colostomy patients, and whether disgust predicts stigmatizing attitudes about colostomy in non-patients. 195 patients with a colostomy returned a mailed survey including measures of disgust sensitivity, life satisfaction, mood, and feelings of being stigmatized. We also conducted an internet-survey of a non-patient sample (n = 523). In the patient sample, we observed negative correlations between a bowel-specific measure of disgust sensitivity and life satisfaction (r = -.34, p<.01), and colostomy adjustment ( r = -.42, p<.01), and a positive correlation with feeling stigmatized because of the colostomy (r = .54, p<.01). Correlations between a general trait disgust measure and these outcomes were more modest. A structural equation model indicated that colostomy patients who had high disgust sensitivity felt more stigmatized, and this was in turn strongly related to lower life satisfaction. Concordantly, in the non-patient sample we observed that disgust sensitivity was a significant, positive predictor of wanting less contact with colostomy patients (r = .22, p < .01).     

Open-field behavior in two models of genetic hypertension and the behavioral effects of salt excess

In order to assess the relationship of behavior to blood pressure and salt intake, open-field behavior was studied in 123 rats of the spontaneously hypertensive (SHR), Wistar-Kyoto (WKY), Sprague-Dawley (SD), and Dahl resistant (DR) and sensitive (DS) strains. DS rats become hypertensive upon exposure to either high dietary salt or psychogenic stress, while DR rats remain normotensive. A circular photobeam open field was used under full room illumination. Three 5-min trials were given on consecutive days. Rats were tested with or without 5 days of an 8% NaCl diet. We found that DS rats were less active than DR rats, regardless of diet. In contrast, SHR rats were more active than WKY rats. However, DS and SHR rats were equally active. Thus, behavioral differences between these two models of hypertension are expressed by the normotensive control strains. The relative ranking of activity levels between strains was DR = SD greater than SHR = DS greater than WKY. High-salt-enhanced intertrial habituation, defined as the decrease in activity across trials (DS, 100%; SD, 82%; SHR, 90%; WKY, 1350%; but DR, -50%) as well as intratrial habituation, defined as the decrease from the first to the second half of the trial (14%, all subjects). Defecation was increased with high salt (DS, 975%; SD, 59%; SHR, 267%; WKY, 89%; but DR, 40%). These effects of high salt may reflect an increase in an emotionality factor. DR rats were largely resistant to the behavioral effects of salt. Total activity was positively correlated with blood pressure in hypertensive rats, r(42) = 0.33, p less than .01, but negatively correlated in normotensive rats, r(81) = -0.34, p less than .01. The proportion of total activity occurring in the first half of the trial for the initial test day was correlated with blood pressure in normotensive rats r(81) = 0.44, p less than .01. Dietary salt excess has behavioral as well as cardiovascular consequences.     

Abortion outcome as a function of sex-role identification

The present study investigated the relationship between sex-role identification and abortion outcome in 120 women receiving first trimester abortions. The sex-role concept dimension was measured both by self-attributions of sex-role traits (as measured by the Bern Sex-Role Inventory) and by life-style (career vs. homemaker) trait attributions. Psychological and physiological aspects of abortion outcome were included; slightly more than 7% of scores were in the symptomatic range, similar to percentages found in previous studies. Both Androgyny (r = -.42, p <.001) and Masculinity (r = -.23, p <.05) were found to be related to positive abortion outcome. Androgyny was more strongly related, which suggests that a balance of masculine and feminine traits, at least for women in the post-abortion situation, is preferable to high Masculinity scores alone. Congruence between one's self-image and one's image of a career woman was also found to be related to abortion outcome (r =.31, p <.01). In attempting to differentiate between the upper and lower 10% of the distribution of abortion outcome, only two variables, Androgyny and self-career congruence, survived parameter criterion, and accounted for 32% of the variance.     

Low heart rate variability is not caused by typical neuroleptics in schizophrenia patients

Both elevated cardiovascular mortality and low cardio-vagal (parasympathetic) heart rate variability (HRV)--a risk factor for postmyocardial infarction--are reported in schizophrenia (SZ). Since a number of medications have strong effects of cardiac conductivity, we thought it important to examine if typical neuroleptic medications might also affect HRV. We examined cardiac vagal activity during both neuroleptic treatment and a drug-free condition in seven SZ patients who were participating in a pilot double-blind, crossover study of placebo and haloperidol treatment. Twenty-four-hour Holter electrocardiograms were analyzed for high frequency HRV, quantitated as the percent of successive normal interbeat intervals greater than 50 milliseconds (PNN50), which is a good index of parasympathetic cardiac modulation. The patients showed unchanged PNN50 (8.4+/-9.5 versus 8.3+/-10.5; t=.22, df=6, P=.5) between the haloperidol treatment and drug-free conditions. Despite the elapsed time, change in medication, and altered clinical state, the PNN50s were highly correlated (Spearman r=.98, P=.000). SAPS positive symptom scores declined with treatment from 12.8+/-6.5 to 8.5+/-3.5; paired t=3.26: df=6; P=.01. PNN50s were significantly associated with positive (r=-.86, df=6, P=.012) and negative symptom scores (r=-.87, df=6, P=.01). We found low cardiovagal modulation in medication-free SZ patients that was associated with core SZ symptoms and was unchanged by haloperidol and benztropine treatment. The reduced HRV in SZ patients at baseline may render them at greater cardiovascular risk than healthy subjects when treated with medications having strong cardiovascular effects.     

组织政治氛围对员工疏离感的影响：自我决定动机的中介作用

验证组织政治氛围对员工疏离感的作用,探讨自我决定动机在二者间的中介作用。研究采用一般政治行为知觉量表、工作内外动机量表和工作疏离感量表对226名企事业单位的员工进行问卷调查。研究表明,组织政治氛围对员工疏离感的个人疏离和社会疏离均具有显著的预测作用;自我决定动机在组织政治氛围与员工的个人疏离感之间起部分中介的作用,但在组织政治氛围与员工的社会疏离感之间的中介作用不显著。这说明我国员工的个人疏离感一部分来自于组织政治氛围对员自我决定动机的削弱,而社会疏离感主要来自于组织政治氛围的直接影响。     

双文化认同整合与心理适应的关系:辩证性自我的中介作用

本研究从双文化人对于文化认同的主观感知视角出发,采用问卷调查法,以藏汉杂居区的藏族大学生和汉文化区域的藏族寄居大学生为例,探讨双文化认同整合、辩证性自我与心理适应之间的关系,以及辩证性自我在两者之间的中介作用。结果表明:(1)对于两类被试来说,双文化认同整合问卷的和谐冲突维度与心理适应呈显著正相关,与辩证性自我呈显著负相关;但不同的是,藏族杂居区的被试,双文化认同整合的混合区分维度与辩证性自我和心理适应的相关都不显著(2)辩证性自我在双文化认同整合(和谐-冲突维度)与心理适应的关系中起中介作用。实践中,应通过加强少数民族大学生的双文化认同整合,降低其冲突心理、增强矛盾容忍性等辩证主义思想,进而增强其心理适应。
