Anxiety and Depression in Brazilian Orthopaedics Inpatients: A Cross Sectional Study with a Clinical Sample Comparison

There are few studies on the development of anxiety and depression in orthopaedics and trauma (O&T) inpatients. We designed a cross-sectional study aimed at comparing the prevalence of depression and anxiety in 100 O&T inpatients and 100 clinical inpatients in the same hospital. O&T patients were divided into subgroups: trauma and non-trauma (arthroplasty, tumour, and infection sub grouping). We measured anxiety and depression by the Hospital Anxiety and Depression Scale and co-morbidities by the Charlson age-adjusted comorbidity index (CCI). For the trauma subgroup, AO/OTA fracture classification and Gustillo and Anderson grade of open fractures classification was applied. The prevalence of anxiety and depression was 35% and 28%, respectively for the clinical sample, and 44% and 33% for the O&T sample. Compared with the clinical sample, anxiety scores were higher in the O&T sample (p = .047), and in arthroplasty (p = .020) and trauma subgroups (p = .031). In the O&T sample, high CCI scores were associated with high anxiety scores (p = .033).     

Prenatal dysthymia versus major depression effects on the neonate

Depressed pregnant women were classified as dysthymic or major depression disorder based on the Structured Clinical Interview for Depression and followed to the newborn period. The newborns of dysthymic versus major depression disorder mothers had a significantly shorter gestational age, a lower birthweight, shorter birth length and less optimal obstetric complications scores. The neonates of dysthymic mothers also had lower orientation and motor scores and more depressive symptoms on the Brazelton Neonatal Behavioral Assessment Scale. These findings were not surprising given the elevated cortisol levels and the inferior fetal measures including lower fetal weight, fetal length, femur length and abdominal circumference noted in our earlier study on fetuses of dysthymic pregnant women.     

The users of an online psychological advice service: a sociodemographic analysis

Although online psychological services and research based on them are increasing rapidly, it is not that easy to find investigations that focus on the kind of people that demand them. To know their profile could help to improve the online psychological services that are offered to them. For this purpose, we analysed the sociodemographic characteristics of 1052 participants, all of them having posed a psychological question to our online advice service. The relations between sociodemographics and variables related to the psychological consultation are analysed herein. Features such as age distribution, a high proportion of long-term problems, the large quantity of questions from Latin America, or the under representation of the lowest socioeconomic and educational levels could lead to clinical, social and legal implications that we comment on in this work.     

Sensitivity to pain, self-regulation, coping and personality in healthy adult women

The goals of this study were to investigate the relation between sensitivity to pain and subjectively perceived intensity of pain, and to establish which psychological variables affect lesser or greater objective sensitivity to experimental pain. The study sample consisted of 74 adult women without regular pain symptoms. Experimental pain was induced by means of the Portable Electronic Dolorimeter (DEP). Intensity of induced pain was evaluated using a Visual Analogic Scale (VAS). Psychological characteristics studied were self-government, stress-coping strategies, sensitivity to anxiety and the five personality dimensions evaluated by the BFQ of Caprara, Barbaranelli and Borgogni (1995). Results revealed a positive relation between sensitivity to pain and subjective intensity of pain. An analysis of variance also revealed statistically significant differences between groups with low and high sensitivity to pain in the following variables: self-motivation, focalization in problem-solving, positive reappraisal of stressful events, energy and mental openness. The importance of the study lies in the identification of specific psychological factors for intervention in the psychological treatment of pain.     

Evaluation of three sensitivity measures in magnitude estimation tasks

Taking into account the studies about the measure of sensitivity in magnitude estimation tasks, we analyze the three most common measures used in this topic: Pearson's product-moment correlation between the logarithm of the stimulus and the logarithm of the response (R), the exponent of Stevens' power function (K), and the measure "M" proposed by Garriga-Trillo. Using a sample of participants greater than usual in psychophysical studies (180 participants), we designed an experiment with two sets of stimuli with different stimulus ranges. In each of these sets, we used two kinds of stimuli (line segments and squares). Our conclusions were: (1) we rejected the use of K as a sensitivity measure because the results provided by this index were the opposite of those expected when we compared the two stimulus ranges. (2) We also rejected the use of M because this measure is a linear transformation of Kendall's coefficient of concordance. (3) Lastly, we suggest the mathematical transformation proposed by Fisher to achieve a normal distribution, and recommend this transformation as the best sensitivity measure.     

Backward blocking: the role of within-compound associations and interference between cues trained apart

Most theoretical accounts of backward blocking place heavy stress on the necessity of the target cue having been trained in compound with the competing cue to produce a decrement in responding. Yet, other evidence suggests that a similar reduction in responding to the target cue can be observed when the outcome is later paired with a novel cue never trained in compound with the target cue (interference between cues trained apart). The present experiment shows that pairing another nonassociated cue with the same outcome may be sufficient to produce a decremental effect on the target cue, but the presence of a within-compound association between the target and the competing cue adds to this effect. Thus, both interference between cues trained apart and within-compound associations independently contribute to backward blocking.     

Defining racism safely: The role of self-image maintenance on white Americans’ conceptions of racism

We suggest that the need to maintain a positive self-image motivates White Americans to conceive of racism as a phenomenon rooted in individuals instead of institutions. They do so because an institutional conception of racism, more so than an individual conception of racism, raises their awareness of White privilege, a concept threatening to Whites’ self-image. In support of this idea, Experiment 1 found that a self-affirmation manipulation increased Whites’ willingness to conceive racism in institutional terms. Experiment 2 found that a self-image threat lowered Whites’ willingness to conceive racism in institutional terms. In neither experiment did the self-image maintenance manipulation affect Whites’ conceptions of individual racism, suggesting that the individual conception of racism may be a less ego-threatening way for Whites to conceive of racism.     

Mental workload and visual impairment: differences between pupil, blink, and subjective rating

This research has two aims: (a) To study the concurrent validity of three measures of mental workload, NASA TLX rating scale, pupil dilation and blink rate, testing the hypothesis that they will provide convergent results using a single-task, and dissociative results for dual-task; and (b) To analyse their capability to predict visual search impairment. These three measures were analyzed in the same cognitive tasks in single-task and dual-task (cognitive task and visual search) conditions in a within-subjects experiment with twenty-nine participants. Mental workload measures showed concurrent validity under single-task condition, but a complex pattern of results arose in the dual-task condition: it is suggested that NASA TLX would be a subjective addition of the rating of each task; pupil dilation would measure the average arousal underlying the cognitive tasks; and the blink rate would produce opposite effects: whereas mental workload of cognitive tasks would increase blink rate, visual demand would inhibit it. All three measures were good predictors of visual impairment. The soundness of these measures is discussed with regard to the applied field of driving and other activities.     

A practical method for analyzing factorial designs with heteroscedastic data

The Type I error rates and powers of three recent tests for analyzing nonorthogonal factorial designs under departures from the assumptions of homogeneity and normality were evaluated using Monte Carlo simulation. Specifically, this work compared the performance of the modified Brown-Forsythe procedure, the generalization of Box's method proposed by Brunner, Dette, and Munk, and the mixed-model procedure adjusted by the Kenward-Roger solution available in the SAS statistical package. With regard to robustness, the three approaches adequately controlled Type I error when the data were generated from symmetric distributions; however, this study's results indicate that, when the data were extracted from asymmetric distributions, the modified Brown-Forsythe approach controlled the Type I error slightly better than the other procedures. With regard to sensitivity, the higher power rates were obtained when the analyses were done with the MIXED procedure of the SAS program. Furthermore, results also identified that, when the data were generated from symmetric distributions, little power was sacrificed by using the generalization of Box's method in place of the modified Brown-Forsythe procedure.
