RESUMO

The aim of this study was to conduct a Polish adaptation of Process-Based Assessment Tool (PBAT), to be used primarily for measurement of the processes of change occurring within psychological interventions, regardless of the therapeutic approach. PBAT includes a set of statements related to negative and positive behaviors in the domains of selection, variation, and retention, as it is theoretically embedded in the evolutionary approach. The tool's construction was determined by resolving the issue of ergodic error, hence employs an idiographic approach. A total of 602 (319 F, 281 M) participants in the age 18-85 took part in the study. Apart from the original 21 PBAT items, two additional items related to self-care vs. self-impatience were tested. The included criterion variables related to the assessment of individual functioning in terms of distress (sadness, anxiety, stress, anger, lack of social support), health (health and vitality levels), the fulfillment or frustration of autonomy, connection, and competence need, as well as well-being (life-satisfaction and sense of professional burnout). The machine learning Boruta algorithm was utilized. PBAT items significantly predicted criterion variables. Positive selection behaviors were strongest predictors of Health, Vitality, Life-satisfaction as well as satisfaction of autonomy, connection and competence needs. Negative selection behaviors were strongest predictors of distress, lack of social support, work burnout as well as the frustration of autonomy, connection and competence needs. Overall, the PBAT items were more predictive of variables encompassing negative aspects of functioning than positive aspects or well-being. The overall relationships and conclusions are consistent with those obtained in the original study. The Polish version of PBAT is recommended for use in further scientific research and therapeutic processes.

RESUMO

Pain may alter intertemporal decisions by modifying the value of pain-related outcomes. For example, a person with chronic back pain may be faced with two choices: undergo surgery that could provide long-term relief but would involve additional short-term pain and discomfort during recovery; or continue living with the chronic pain and avoid the surgery, thus leading to overall deteriorated health. Such choices are well captured by delay discounting, which is defined as the decline in the subjective value of an outcome as the delay of its receipt increases. We investigated general pain anxiety and delay discounting of monetary losses and pain in 255 individuals with and without chronic pain. We found that people with chronic pain tend to discount the value of pain outcomes more than those without chronic pain, suggesting that chronic pain may contribute to impulsivity in decision-making related to pain. Moreover, the effect of chronic pain on delay discounting was mediated through general pain anxiety. This result, however, should be taken with caution, because the effect sizes were small, and the path model was underpowered. In conclusion, people with chronic pain might be more likely to prioritize avoiding immediate discomfort and may undervalue the potential long-term benefits of actions that could alleviate their pain in the future.

RESUMO

In some circumstances rule-governed behavior, a behavior that is governed by verbal rules instead of environmental consequences, may be beneficial for human beings. At the same time, rigid rule following is associated with psychopathology. Thus measurement of rule-governed behavior may be of special use in a clinical setting. The aim of this paper is to assess the psychometric properties of Polish adaptations of three questionnaires measuring generalized tendency to engage in various types of rule-governed behaviors: Generalized Pliance Questionnaire (GPQ), Generalized Self-Pliance Questionnaire (GSPQ), Generalized Tracking Questionnaire (GTQ). A forward-backward method was used for translation. Data was collected from two samples: general population (N = 669) and university students (N = 451). To measure the validity of the adapted scales the participants filled in a set of self-assessed questionnaires: Satisfaction with Life Scale (SWLS), Depression, Anxiety, and Stress Scale- 21 (DASS-21), General Self-Efficacy Scale (GSES), Acceptance and Action Questionnaire-II (AAQ-II), Cognitive Fusion Questionnaire (CFQ), Valuing Questionnaire (VQ) and Rumination-Reflection Questionnaire (RRQ). The exploratory and confirmatory analyses confirmed the unidimensional structure of each of the adapted scales. All of those scales presented good reliability (internal consistency measured with Cronbach Alpha) and item-total correlations. The Polish versions of questionnaires presented significant correlations in the expected directions with relevant psychological variables in line with the original studies. The measurement occurred invariant across both samples as well as gender. The results provide evidence that Polish versions of GPQ, GSPQ and GTQ present sufficient validity and reliability to be used in the Polish-speaking population.

RESUMO

Purpose: To illustrate the processes of development within the behavioral theory and the corresponding expansion of the areas in which it is applied, especially the advancement (conceptual developments) of the functional analysis of language inspired by Relational Frame Theory (RFT) research. Views: Classical and operant conditioning are well-established behavioral learning processes, discovered and described at the beginning of the twentieth century. They provide the tools for analyzing, establishing and modifying the functions of stimuli and responses of the organisms through manipulation of the environment. Although B. F. Skinner provided grounds for the functional analysis of complex behaviors such as language, it was not until the beginning of the twenty-first century that RFT was introduced. From this moment behavior analysts could use behavioral principles to explain how stimulus functions may change without direct learning. The practical application of the growing knowledge about Arbitrarily Applicable Relational Responding (AARR), a basic generalized operant described within RFT, allows us to analyze, explain and change behaviors that had hitherto been beyond the scope of behavioral therapy. The continued growth and development of behavior theory and practice holds the promise for an expansion of its application to new areas and populations in need. One such development is the functional analysis of verbal behavior e.g., relational frames, ROE (relating-orienting-evoking). Conclusions: It seems useful to add advancements proposed by RFT to the behavioral toolbox with which we could effectively describe, explain and change behavior with precision, scope and depth.

RESUMO

Introduction: This study compared the effectiveness of different types of reinforcement (positive, negative, and a combination of both) in a self-management intervention program designed to increase water intake and walking. Methods: Four university students participated in a self-management program to increase water intake and walking. Multiple baseline design across behaviors that included baseline (A) condition, positive reinforcement (B) condition, negative reinforcement (C) condition, and combination of both (B + C), was introduced. The participants received $2 every day they met the criteria during the positive reinforcement condition and no consequence if they failed to meet the criteria. In the negative reinforcement condition, $2 was subtracted for each day that the participant did not meet the criteria from the total amount of money available to the participant during that phase of the study. During the condition with positive and negative reinforcement, the participants received $2 every day they met the criteria. However, $2 was subtracted from the total for every day they did not meet the criteria. Results: There was a clear increase from baseline to the first intervention phase across all the behaviors and participants, and the increase was maintained throughout the study. There were no differences in the effectiveness of different types of reinforcement applied in self-management intervention programs. Conclusions: The study did show that implementing a relatively low-cost reinforcement contingency increased both exercise and water drinking. The results suggest that there are no consistent differences in the effectiveness of positive or negative reinforcement contingencies in self-management intervention.

RESUMO

Loss aversion entails that people attribute greater weight to losses than to equivalent gains. In terms of discounting, it is reflected in a higher discounting rate for gains than for losses. Research on delay discounting indicates that such gain-loss asymmetry may depend on the amount of the outcome being considered. Consequently, here we address the question of how gains and losses are discounted in delay or effort conditions (physical or cognitive) across four outcome amounts. Our results replicate previous findings for intertemporal choices by showing that losses are discounted more slowly than gains, but only for smaller amounts-with no evidence of an asymmetrical evaluation for larger amounts. In physical effort discounting, we found an inverse asymmetry for the smallest amount tested (gains are discounted less steeply than losses). However, this effect was absent for larger amounts. We found no evidence to support a gain-loss asymmetry in the evaluation of gains or losses in cognitive effort. Overall, our findings indicate that loss aversion may not be as pervasive as previously expected, at least when decisions are effort-based.

RESUMO

CONTEXT: Early feeding practices may influence the acceptance of new foods and contribute to the development of feeding difficulties later in childhood. OBJECTIVE: The aim of this systematic review was to evaluate the association of breastfeeding duration, timing of complementary feeding introduction, and feeding techniques with feeding difficulties or their subtypes, namely picky or fussy eating, food refusal, and food neophobia, in children older than 1 year of age. DATA SOURCES: Guidance from the Cochrane Collaboration and the Centre for Reviews and Dissemination was followed. MEDLINE, Embase, and PsycINFO databases were searched up to December 2019. Additionally, references from included articles were screened. STUDY SELECTION: Interventional and observational studies were eligible. Of the 3653 records obtained after the search strategy was applied, 21 observational studies (cohort, case-control, cross-sectional), many with important methodological limitations, and 1 randomized controlled trial were included. DATA EXTRACTION: Three authors extracted data independently. RESULTS: Results were synthesized narratively. Twelve observational studies assessed the association of breastfeeding duration with parent-reported feeding difficulties. Longer duration of breastfeeding tended to be associated with fewer childhood feeding problems in the majority of studies, but the differences were often small and not significant. Eight observational studies that examined the timing of complementary feeding introduction in relation to parent-reported feeding difficulties showed inconsistent results. Baby-led weaning, as compared with spoon-feeding, was significantly associated with less fussiness at age 12 to 36 months in 1 of 5 studies. CONCLUSIONS: This review showed no strong evidence to support the hypothesis that early feeding practices contribute significantly to specific parent-reported feeding difficulties in children older than 1 year of age. Additional methodologically rigorous studies are needed to confirm these findings. SYSTEMATIC REVIEW REGISTRATION: PROSPERO registration number CRD42018115792.

RESUMO

Discounting refers to decreases in the subjective value of an outcome with increases in some attribute of that outcome. The attributes most commonly studied are delay and probability, with far less research on effort and social discounting. Although these attributes all represent costs that reduce subjective value, it is as yet unclear how the extent to which they do so is related at the individual level. Accordingly, the present study examined the degree to which individual participants discounted hypothetical monetary rewards on each of four discounting tasks in which the delay, probability, effort, and number of people with whom the money was to be shared were manipulated. At the group level, larger amounts were discounted less steeply than smaller amounts when delay and effort were varied, whereas larger amounts were discounted more steeply when probability and number of people were varied. At the individual level, the correlational pattern was examined using exploratory factor analysis. A six-factor structure (with separate factors for delay and effort, and two factors each for social and probability discounting) described the relations among indifference points. At a more molar level, a two-factor structure, which corresponded to the direction of the observed magnitude effects, described the relations among area-under-the-curve measures of discounting in the eight conditions resulting from crossing two monetary amounts with the four cost factors. We conclude that despite sharing some similarities, individual and group differences in discounting involving the different types of costs reflect mostly separate processes and traits.

RESUMO

Lipedema is a chronic, progressive adipose tissue disorder that may impact the quality of life of women who suffer from it. The main aim of this study was to asses the role of perceived symptom severity, physical and psychological functioning with the disease in predicting quality of life in patients with lipedema. We conducted an online study with 329 participants who responded to five questionnaires measuring quality of life (World Health Organization Quality of Life BREF), lipedema symptom severity, mobility (Lower Extremity Functional Scale), depression (Patients Health Questionnaire-9), and appearance-related distress (Derriford Appearance Scale 24). Multiple hierarchical regression analyses showed that appearance-related distress and depression explained significantly more variance in quality of life when added to the symptom severity and mobility. Lower quality of life was predicted by higher symptom severity, lower mobility, higher appearance-related distress and higher depression severity. Appearance-related distress and depression constitute important aspects of psychological functioning in women with lipedema. Considering their relationship with quality of life, their assessment should be included in lipedema treatment with appropriate interventions aimed at decreasing appearance-related distress, as well as preventing and addressing depression.

RESUMO

The effort required to obtain a rewarding outcome is an important factor in decision-making. Describing the reward devaluation by increasing effort intensity is substantial to understanding human preferences, because every action and choice that we make is in itself effortful. To investigate how reward valuation is affected by physical and cognitive effort, we compared mathematical discounting functions derived from research on discounting. Seven discounting models were tested across three different reward magnitudes. To test the models, data were collected from a total of 114 participants recruited from the general population. For one-parameter models (hyperbolic, exponential, and parabolic), the data were explained best by the exponential model as given by a percentage of explained variance. However, after introducing an additional parameter, data obtained in the cognitive and physical effort conditions were best described by the power function model. Further analysis, using the second order Akaike and Bayesian Information Criteria, which account for model complexity, allowed us to identify the best model among all tested. We found that the power function best described the data, which corresponds to conventional analyses based on the R2 measure. This supports the conclusion that the function best describing reward devaluation by physical and cognitive effort is a concave one and is different from those that describe delay or probability discounting. In addition, consistent magnitude effects were observed that correspond to those in delay discounting research.

RESUMO

BACKGROUND: Impaired orienting to social stimuli is one of the core early symptoms of autism spectrum disorder (ASD). However, in contrast to faces, name processing has rarely been studied in individuals with ASD. Here, we investigated brain activity and functional connectivity associated with recognition of names in the high-functioning ASD group and in the control group. METHODS: EEG was recorded in 15 young males with ASD and 15 matched one-to-one control individuals. EEG data were analyzed with the event-related potential (ERP), event-related desynchronization and event-related synchronization (ERD/S), as well as coherence and direct transfer function (DTF) methods. Four categories of names were presented visually: one's own, close-other's, famous, and unknown. RESULTS: Differences between the ASD and control groups were found for ERP, coherence, and DTF. In individuals with ASD, P300 (a positive ERP component) to own-name and to a close-other's name were similar whereas in control participants, P300 to own-name was enhanced when compared to all other names. Analysis of coherence and DTF revealed disruption of fronto-posterior task-related connectivity in individuals with ASD within the beta range frequencies. Moreover, DTF indicated the directionality of those impaired connections-they were going from parieto-occipital to frontal regions. DTF also showed inter-group differences in short-range connectivity: weaker connections within the frontal region and stronger connections within the occipital region in the ASD group in comparison to the control group. CONCLUSIONS: Our findings suggest a lack of the self-preference effect and impaired functioning of the attentional network during recognition of visually presented names in individuals with ASD.

RESUMO

N-methyl-d-aspartate receptors (NMDARs) play a crucial role in spatial memory formation. In neuropharmacological studies their functioning strongly depends on testing conditions and the dosage of NMDAR antagonists. The aim of this study was to assess the immediate effects of NMDAR block by (+)MK-801 or memantine on short-term allothetic memory. Memory was tested in a working memory version of the Morris water maze test. In our version of the test, rats underwent one day of training with 8 trials, and then three experimental days when rats were injected intraperitoneally with low- 5 (MeL), high - 20 (MeH) mg/kg memantine, 0.1mg/kg MK-801 or 1ml/kg saline (SAL) 30min before testing, for three consecutive days. On each experimental day there was just one acquisition and one test trial, with an inter-trial interval of 5 or 15min. During training the hidden platform was relocated after each trial and during the experiment after each day. The follow-up effect was assessed on day 9. Intact rats improved their spatial memory across the one training day. With a 5min interval MeH rats had longer latency then all rats during retrieval. With a 15min interval the MeH rats presented worse working memory measured as retrieval minus acquisition trial for path than SAL and MeL and for latency than MeL rats. MK-801 rats had longer latency than SAL during retrieval. Thus, the high dose of memantine, contrary to low dose of MK-801 disrupts short-term memory independent on the time interval between acquisition and retrieval. This shows that short-term memory tested in a working memory version of water maze is sensitive to several parameters: i.e., NMDA receptor antagonist type, dosage and the time interval between learning and testing.

RESUMO

PURPOSE: Lipoedema is a chronic, progressive adipose disorder of unknown etiology, often underdiagnosed or misdiagnosed as obesity. It manifests itself with accumulation of the fat in lower parts of the body and associated edema and, due to numerous physical and psychological consequences, affects the quality of life (QOL) of those who suffer. The aim of this study was to investigate the psychological factors that might have an impact on the QOL of women with lipoedema from the contextual behavioral viewpoint. METHODS: In an Internet-based cross-sectional study, women suffering from lipoedema (N = 120) were asked to fill in questionnaires assessing: symptom severity, QOL (WHOQOL-BREF), satisfaction with life (SWLS), psychological flexibility (Acceptance and Action Questionnaire-II), social connectedness (Social Connectedness Scale-Revised) and other psychological factors. The majority of participants were from the USA, the UK, and Australia. RESULTS: Multiple hierarchical regression analyses showed that a higher level of QOL was predicted by higher levels of psychological flexibility and social connectedness, while controlling for symptom severity. Higher level of SWL was predicted only by higher level of social connectedness. CONCLUSIONS: Acceptance and Commitment Therapy with psychological flexibility as the target of change and Functional Analytic Psychotherapy with social connectedness as the target of change might be useful in treating women with lipoedema; however, further research in this area is needed. The authors conclude that psychological and biomedical interventions for women with lipoedema and their QOL merit more attention from researchers and the medical community than is currently received.

RESUMO

Adverse early experience is generally regarded as a risk factor for both externalizing and internalizing behavioral disorders in humans. It can be modeled in rats by a post-weaning social isolation procedure. Effects of social isolation might possibly be ameliorated by environmental enrichment. In the current study, 24 male Wistar rats were divided post-weaning into four rearing conditions: control, environmental enrichment (EE), social isolation (SI) and a combination of the two experimental conditions; (EE+SI). Two observations of the effects of rearing conditions on the rate of social and object interactions were conducted during the juvenile and post-pubertal stages of development. The SI condition led to a marked increase of social interactions during the juvenile phase, but did not affect object interactions. The EE condition increased the level of social interactions during both the juvenile and post-pubertal measurements. The effects of early rearing conditions on adult exploratory behavior were less clear, with a significant difference between the groups obtained in one of three behavioral tests. Results suggest a general robustness in the development of adult exploratory behavior and anxiety when rats were exposed to early social isolation and provided brief opportunities for social play during the juvenile period. Further studies, aimed at distinguishing play-related protective factors serving against long-term adverse effects of juvenile social isolation, are suggested.

RESUMO

The purpose of the present study was to test the prediction that when two rewards, a smaller but "socially closer" one and a larger but "socially more distant" one, are moved away from the subject by the same social distance, subjective value of the socially more distant reward will increase (i.e. the rate of social discounting will be shallower). The effect was absent when the recipients were moved back 10 places, but emerged when they were moved back 20 places. In addition, the hyperbolic model was found to correctly describe choices between two socially distant rewards. The results confirm similarities between social and temporal discounting.

RESUMO

Autism spectrum disorder (ASD) is a heterogeneous neurodevelopmental condition clinically characterized by social interaction and communication difficulties. To date, the majority of research efforts have focused on brain mechanisms underlying the deficits in interpersonal social cognition associated with ASD. Recent empirical and theoretical work has begun to reveal evidence for a reduced or even absent self-preference effect in patients with ASD. One may hypothesize that this is related to the impaired attentional processing of self-referential stimuli. The aim of our study was to test this hypothesis. We investigated the neural correlates of face and name detection in ASD. Four categories of face/name stimuli were used: own, close-other, famous, and unknown. Event-related potentials were recorded from 62 electrodes in 23 subjects with ASD and 23 matched control subjects. P100, N170, and P300 components were analyzed. The control group clearly showed a significant self-preference effect: higher P300 amplitude to the presentation of own face and own name than to the close-other, famous, and unknown categories, indicating preferential attentional engagement in processing of self-related information. In contrast, detection of both own and close-other's face and name in the ASD group was associated with enhanced P300, suggesting similar attention allocation for self and close-other related information. These findings suggest that attention allocation in the ASD group is modulated by the personal significance factor, and that the self-preference effect is absent if self is compared to close-other. These effects are similar for physical and non-physical aspects of the autistic self. In addition, lateralization of face and name processing is attenuated in ASD, suggesting atypical brain organization.

RESUMO

The aim of the study was to investigate the relationship between Cloninger's personality dimensions of temperament (Harm Avoidance, Novelty Seeking, Reward Dependence, and Persistence) and the steepness of delay and effort discounting, which refers to a decrease in the subjective value of a reward as its delay, or effort required to obtain the reward, increases. Participants (N = 112; ages 19 to 29 years, M = 21.80, SD = 1.35) filled out two inventories: the Temperament and Character Inventory (TCI) and the Discounting Questionnaire. The study revealed that the higher the Harm Avoidance and Reward Dependency, the steeper the effort discounting. On the other hand, the higher one's Persistence, the shallower one's effort discounting. Finally, a positive correlation was observed between delay and effort discounting. The results indicated that effort discounting was related to, but not equivalent to, delay discounting.

RESUMO

The main purpose of this study was to determine whether the magnitude effect is present in cases where delayed sequences of rewards are discounted. The magnitude effect refers to the inverse relationship between the amount of a reward and the steepness of temporal discounting. This study was conducted with a computer program to estimate the indifference points, which served as indicators of the present subjective value of delayed sequences of small and large rewards. In the indifference point the subjective value of a single, immediate reward was equal to the subjective value of the delayed sequence (or to the value of a single delayed reward). As a control condition, we added an experimental task involving choices between single immediate and single delayed rewards. The experiment showed that the sequences of large rewards are discounted less steeply than are the sequences of small rewards. This finding suggests that the magnitude effect is present within the delayed sequences of rewards. In addition, when outcomes are relatively large, the results suggest that a single reward is discounted less steeply than the sequence of a total nominal value equal to this single reward. However, for relatively small rewards, the difference is not statistically significant. The less steep discounting of sequences of large rewards may explain the reward-bundling effect, which refers to less steep discounting of longer sequences than of shorter ones: longer sequences usually have greater overall nominal value. The present study was conducted on hypothetical rewards, and the results should be validated using real rewards.

RESUMO

BACKGROUND: Measuring quality of life (QOL) helps to delineate mechanisms underlying the interaction of disease and psychosocial factors. In adults, epileptic foci in the left temporal lobe led to lower QOL and higher depression and anxiety as compared to the right-sided foci. No study addressed the development of QOL disturbances depending on the lateralization of epileptogenic focus. The objective of our study was to examine QOL in children with lateralized epileptiform discharges. METHODS: Thirty-one parents of children with epilepsy filled the Health-Related Quality of Life in Childhood Epilepsy Questionnaire (QOLCE). Fifteen children had foci in the left hemisphere and sixteen in the right, as verified with Electroencephalography (EEG) examinations. RESULTS: We found a significant correlation between foci lateralization and reduced QOL (Spearman's rho = 0.361, p < 0.046). Children with right hemispheric foci exhibited lower overall QOL, particularly in five areas: anxiety, social-activities, stigma, general-health, and quality-of-life. CONCLUSIONS: We demonstrated for the first time that in children left- and right-hemispheric foci were associated with discordant QOL scores. Unlike in adults, foci in the right hemisphere led to worse emotional and social functioning demonstrating that seizures impact the brain differentially during development.
