Multidimensional signal detection analyses (MSDA) for testing separability and independence: A Pascal program

A Pascal (Turbo 6.0) program for testing perceptual separability, decisional separability, and perceptual independence—three types of independence defined in the context of general recognition theory (GRT)—is presented. GRT is essentially a multidimensional extension of signal detectability theory (Green & Swets, 1966) and has been employed in complete-identification experimental paradigms to examine whether information processing of stimulus dimensions is perceptually and/or decisionally separable and/or perceptually independent. The definitions of these different forms of “independence” are provided, the experimental design is described, and the program, MSDA, is described and demonstrated.     

On estimation and hypothesis testing problems for correlation coefficients

A selection of statistical problems commonly encountered in psychological or psychiatric research concerning correlation coefficients are re-evaluated in the light of recently developed simplifications in the forms of the distribution theory of the intraclass correlation coefficient (exact theory), of the product-moment correlation coefficient and of the Spearman rank correlation coefficient (approximate).     

The Association Between Self-Critical Rumination and Parenting Stress: The Mediating Role of Mindful Parenting

Self-critical rumination is a type of rumination focused on the content of self-critical thoughts. Although self-criticism and rumination are two maladaptive psychological processes with a negative effect on parenting, including parenting stress, the role of self-critical rumination on parenting outcomes has never been explored. The aim of this study is to analyze the role of self-critical rumination on parenting stress and examine whether mindful parenting dimensions (listening with full attention, compassion for the child, non-judgmental acceptance of parental functioning, emotional awareness of the child, and self-regulation in parenting) mediate this association. The moderating role of child’s age in the direct and indirect effects was also examined. A sample of 265 Portuguese mothers of children/adolescents from the general community completed measures of self-critical rumination, mindful parenting, and parenting stress. Self-critical rumination was negatively associated with all mindful parenting dimensions and positively associated with parenting stress. However, only non-judgmental acceptance of parental functioning and emotional awareness of the child dimensions were significant mediators of the relationship between self-critical rumination and parenting stress. The link between self-critical rumination and parenting stress as well as the indirect effects were not moderated by the child’s age. This study identifies an important maladaptive psychological process (self-critical rumination) that explains individual differences in parenting and a mechanism that may account for the link between self-critical rumination and parenting stress, which can both be modified through intervention.     

The Network Structure of Childhood Psychopathology in International Adoptees

International adoptees are at an increased risk of emotional and behavioral problems, especially those who are adopted at an older age. We took a new approach in our study of the network structure and predictability of emotional and behavioral problems in internationally adopted children in Finland. Our sample was from the on-going adoption study and comprised 778 internationally adopted children (387 boys and 391 girls, mean age 10.5 (SD 3.4) years). Networks were estimated using Gaussian graphical models and lasso regularization for all the children, and separately for those who were adopted at different ages. The results showed that anxiety/depressive symptoms, social problems, and aggressiveness were the most central symptom domains. Somatic symptoms were the least central and had the weakest effect on the other domains. Similarly, aggressiveness, social problems, and attention problems were high in terms of predictability (73–65%), whereas internalizing problems were relatively low (28–56%). There were clear but local age-group differences in network structure, symptom centrality, and predictability. According to our findings, network models provide important additional information about the centrality and predictability of specific symptom domains, and thus may facilitate targeted interventions among international adoptees.     

Emotional Intelligence Profiles in College Students and Their Fathers’ and Mothers’ Parenting Practices

The present study has two objectives: first, to analyze whether the dimensions that make up emotional intelligence (attention, clarity, and repair) give rise to different profiles of university students, and secondly, to determine whether these different profiles are differentially associated with the parenting practices that students report with regard to their fathers and mothers. Results obtained indicate the existence of different profiles of college students. The profile that corresponds to adequate emotional skills presents a lower score in attention, but higher scores in clarity, and especially in mood repair. The other two profiles are inadequate, in the first case because a higher score in emotional attention is accompanied by low scores in mood repair, and in the second case because low scores are presented in all three dimensions. Likewise, we verified the existence of significant differences in the educational practices of parents, the adequate profile is characterized by greater use of parenting dimensions considered to be positive, and at the same time, lower scores on dimensions considered to be negative. One of the dysfunctional profiles is associated with higher scores in positive practices, and is also associated with higher scores in practices considered to produce a negative effect. The second dysfunctional profile is associated with higher scores on the dimensions considered to be negative and lower scores on positive dimensions.     

A systematic review of psychoneuroimmunology-based interventions

Psychoneuroimmunology-based interventions are used to attenuated disease progression and/or side effects of pharmacological treatment. This systematic review evaluates the different therapeutic and/or clinical psychoneuroimmunology-based interventions associated to both psychological, neuroendocrine and immunological variables. The review was conducted for all English, Portuguese and Spanish language articles published between 2005 and 2015. Independent investigators analyzed 42 studies concerning human psychoneuroimmunology-based interventions. Decreased levels of cortisol, epinephrine and norepinephrine (stress-related hormones) were associated to interventions like yoga, meditation, tai chi, acupuncture, mindfulness, religious/spiritual practices, cognitive behavior therapy, coping and physical exercises. Moreover, those interventions were also associated to reductions in inflammatory processes and levels of pro-inflammatory cytokines in cancer, HIV, depression, anxiety, wound healing, sleep disorder, cardiovascular diseases and fibromyalgia. Despite the associations between PNI variables and clinical/therapeutic interventions, only one study evidenced significant effects on a disease progression.     

<Emphasis Type="Italic">Recta Ratio Agibilium</Emphasis> in a medical context: the role of virtue in the physician-patient relationship

Acting for the good of the patient is the most fundamental and universally acknowledged principle of medical ethics. However, given the complexity of modern medicine as well as the moral fragmentation of contemporary society, determining the good is far from simple. In his philosophy of medicine, Edmund Pellegrino develops a conception of the good that is derived from the internal morality of medicine via the physician-patient relationship. It is through this healing relationship that rights, duties, and privileges are defined for both physicians and patients. Moreover, this relationship determines the characteristics or virtues that are necessary to engage in the medical telos. This paper addresses the role of the moral virtues in clinical medicine and the physician-patient relationship. First, it provides a brief background of the Aristotelian foundations of virtue-ethics. Second, it delves into Pellegrino’s philosophy of medicine understood as a practice oriented towards a teleological goal. Third, it relates the telos of medicine to the notion of the medical community as a fundamentally moral community. Finally, it concludes with a section that creates a dialogue between virtue ethics and principlism.     

Sympathetic reactivity in late pregnancy is related to labour onset in women

Stress regulation during pregnancy is considered to be connected to the timing of labour initiation. Although increasing knowledge is emerging on the regulation of parturition, there is currently no way to predict the start of spontaneous labour in women. The main aim of this study was to assess pain threshold and the sympathetic nervous system response to cold pain in relation to the onset of labour in healthy pregnant women. Ninety-three pregnant women were recruited and assessed for skin conductance (SC) activity during a cold pressor test in gestational week 38. Pain threshold and cold endurance were also measured and the results were compared with data obtained from hospital records. Seventy-four women had a spontaneous labour onset and a valid SC measurement. SC activity during the cold pressor test decreased significantly with the number of days left to spontaneous parturition. This may indicate a gradual decrease in sympathetic autonomic nervous system reactivity even during the last weeks of pregnancy. Measuring SC activity during mild stress provocation is a rapid and non-invasive means to study variation in sympathetic reactivity during pregnancy, and may be useful in research on stress regulation in pregnancy and its relation to labour initiation.     

Short-term effects of a multi-disciplinary cardiac rehabilitation programme on psychological well-being, exercise capacity and weight in a sample of obese in-patients with coronary heart disease: a practice-level study

Given that many patients referred to cardiac rehabilitation (CR) are obese, diet therapy, exercise training, nutritional and psychological counselling for both obesity and psychological distress should be included as important components in all CR programmes. In this practice-level, observational study we evaluated the short-term within-group effects of a four-week multi-factorial inpatient CR programme specifically addressed to weight loss, fitness improvement and psychological health increase on 176 obese in-patients with coronary heart disease (CHD). Outcome measures were exercise capacity measured with estimated metabolic equivalents (METs), body mass index (BMI) and psychological well-being (PGWBI). Results show statistically significant improvements in all the PGWBI sub-scales and total score, except in general health (p = 0.393). No moderation effects were found for BMI class, age, diabetes and ejection fraction (EF). METs significantly increased by 30.3% (p < 0.001) and BMI decreased by 1.37 points (p < 0.001). Significant correlations were found between BMI and weight reductions with PGWBI anxiety and total score improvements. This multi-disciplinary CR programme including diet therapy, exercise training and psychological counselling provides indication for short-term within-group effectiveness on functional exercise capacity, BMI and PGWBI in a sample of obese in-patients with CHD. However, controlled studies are needed to corroborate the results we found.     

Quality of Life (QoL) in a Brazilian Sample of Older Adults: The Role of Sociodemographic Variables and Depression Symptoms

The aim of the present study was to identify relevant variables associated with Quality of Life (QoL) in older adults. Older adults, up to 60 years old, were interviewed. Subjects were recruited through convenience sampling. 339 paticipants, who were stratified by gender, age, and subjective perception of health and illness, answered questions on sociodemographic issues, QoL (WHOQOL-100) and depressive symptomathology (Beck Depression Inventory—BDI). The multiple linear regression analysis showed associations of overall perception of QoL with depression levels, subjective perception of health status and gender. The individual analysis of each domain concluded that depression levels are correlated to all QoL domains, while health status was associated with physical, psychological, independence level and social relationship domains. Other variables were also assessed. The assessment of older adults concerning their QoL perceptions is associated with gender, age, marital status, social class, literacy rate, perception of health, and more substantially associated with depressive symptoms levels. Nevertheless, some limitations of this study and further ones are suggested.
