A modern network approach to revisiting the Positive and Negative Affective Schedule (PANAS) construct validity

Cognitive Signatures of Depressive and Anhedonic Symptoms and Affective States Using Computational Modeling and Neurocognitive Testing

BACKGROUND

Deeper phenotyping may improve our understanding of depression. Because depression is heterogeneous, extracting cognitive signatures associated with severity of depressive symptoms, anhedonia, and affective states is a promising approach.

METHODS

Sequential sampling models decomposed behavior from an adaptive approach-avoidance conflict task into computational parameters quantifying latent cognitive signatures. Fifty unselected participants completed clinical scales and the approach-avoidance conflict task by either approaching or avoiding trials offering monetary rewards and electric shocks.

RESULTS

Decision dynamics were best captured by a sequential sampling model with linear collapsing boundaries varying by net offer values, and with drift rates varying by trial-specific reward and aversion, reflecting net evidence accumulation toward approach or avoidance. Unlike conventional behavioral measures, these computational parameters revealed distinct associations with self-reported symptoms. Specifically, passive avoidance tendencies, indexed by starting point biases, were associated with greater severity of depressive symptoms (R = 0.34, p = .019) and anhedonia (R = 0.49, p = .001). Depressive symptoms were also associated with slower encoding and response execution, indexed by nondecision time (R = 0.37, p = .011). Higher reward sensitivity for offers with negative net values, indexed by drift rates, was linked to more sadness (R = 0.29, p = .042) and lower positive affect (R = -0.33, p = .022). Conversely, higher aversion sensitivity was associated with more tension (R = 0.33, p = .025). Finally, less cautious response patterns, indexed by boundary separation, were linked to more negative affect (R = -0.40, p = .005).

CONCLUSIONS

We demonstrated the utility of multidimensional computational phenotyping, which could be applied to clinical samples to improve characterization and treatment selection.

The psychometric properties of the Persian version of the Demoralization Scale (DS-II) in women with breast cancer

Background

Demoralization is a syndrome of existential distress and despair in patients with cancer and other severe medical illnesses. The Demoralization Scale (DS-II) is self-administered and contains 16 items, and it has two factors: meaning and purpose and distress and coping ability.

Materials and Methods

Women with breast cancer (240) completed the scales DS-II, positive and negative affect, state hope, patient health, and quality of life. Confirmatory factor analysis (CFA) and divergent and convergent validity were used to measure the construct validity of DS-II. CFA was chosen to check the fit of the two-factor model. Divergent and convergent validity were investigated using Pearson's correlation test. The reliability of DS-II was evaluated by the internal consistency method. Cronbach's alpha was used to calculate the internal consistency of the DS-II.

Results

The Cronbach's alpha coefficient for the subscales of meaning and purpose, distress and coping ability, and the total score was obtained: 0.67, 0.72, and 0.81, respectively, indicated this scale's good reliability. Furthermore, the Pearson correlation coefficient results showed the appropriate convergent validity and good divergent validity of the DS-II.

Conclusion

The DS-II has sound psychometric properties and can be recommended as a reliable tool for assessing demoralization in women with breast cancer.

Exploratory graph analysis (EGA) of the dimensional structure of the eating disorder examination-questionnaire (EDE-Q) in women with eating disorders

This study examined the dimensional structure of the German Eating Disorder Examination-Questionnaire (EDE-Q) in clinical groups of women with Anorexia Nervosa (AN; N = 821), Bulimia Nervosa (BN; N = 573), and Binge-Eating Disorder (BED; N = 359) using Exploratory Graph Analyses (EGA). The EGA yielded a 12-item-four-dimension structure for the AN group (subscales "Restraint", "Body Dissatisfaction", "Preoccupation", "Importance"), a 20-item-five-dimension structure for the BN group (subscales "Restraint", "Body Dissatisfaction", "Eating Concern", "Preoccupation", "Importance"), and a 17-item-four-dimension structure for the BED group (subscales "Restraint", "Body Dissatisfaction", "Concern", "Importance"). This first investigation of the EDE-Q's dimensional structure using EGA suggests that the original factor model may be suboptimal for specific clinical ED samples and that alternative scoring should be considered when screening specific cohorts or evaluating the effects of interventions.

Network-based validation of the psychometric questionnaire EDI-3 for the assessment of eating disorders

Assessing the validity of a psychometric test is fundamental to ensure a reliable interpretation of its outcomes. Few attempts have been made recently to complement classical approaches (e.g., factor models) with a novel technique based on network analysis. The objective of the current study is to carry out a network-based validation of the Eating Disorder Inventory 3 (EDI-3), a questionnaire designed for the assessment of eating disorders. Exploiting a reliable, open source sample of 1206 patients diagnosed with an eating disorder, we set up a robust validation process encompassing detection and handling of redundant EDI-3 items, estimation of the cross-sample psychometric network, resampling bootstrap procedure and computation of the median network of the replica samples. We then employed a community detection algorithm to identify the topological clusters, evaluated their coherence with the EDI-3 subscales and replicated the full validation analysis on the subpopulations corresponding to patients diagnosed with either anorexia nervosa or bulimia nervosa. Results of the network-based analysis, and particularly the topological community structures, provided support for almost all the composite scores of the EDI-3 and for 2 single subscales: Bulimia and Maturity Fear. A moderate instability of some dimensions led to the identification of a few multidimensional items that should be better located in the intersection of multiple psychological scales. We also found that, besides symptoms typically attributed to eating disorders, such as drive for thinness, also non-specific symptoms like low self-esteem and interoceptive deficits play a central role in both the cross-sample and the diagnosis-specific networks. Our work adds insights into the complex and multidimensional structure of EDI-3 by providing support to its network-based validity on both mixed and diagnosis-specific samples. Moreover, we replicated previous results that reinforce the transdiagnostic theory of eating disorders.

Association of Affect and Performance in Dual-Task Walking in Non-demented Older Adults

Objective: We examined whether individual differences in positive and negative affective states predicted dual-task costs using an established Dual-Task Walking protocol in non-demented older adults. We hypothesized that positive and negative affect would be associated with smaller and larger dual-task costs, respectively. Methods: Participants (N = 403; mean age = 76.22 ± 6.55; females = 56%) completed the Positive and Negative Affect Schedule and the walking protocol involving three conditions: Single-Task-Alpha, Single-Task-Walk (STW), and Dual-Task-Walk (DTW). Gait velocity was assessed via an instrumented walkway. Results: Negative affect was associated with greater decline in gait velocity from STW to DTW (95% confidence interval [-0.73 to -0.03]) but not the decline of the rate of correct letter generation. There was no significant relationship between positive affect and DTW performance. Discussion: Findings suggest negative affect is adversely associated with allocation of attentional resources, leading to worse mobility outcomes in older adults.

Tasting More Than Just Food: Effect of Aesthetic Appeal of Plate Patterns on Food Perception

Interest has been growing in the role of subjective aesthetics in the field of food. This study explored the mechanisms by which the aesthetic appeal of plate patterns influences consumers’ perceptions of food. Three experiments were conducted to compare whether different levels of beauty and types of plate pattern aesthetics (classical versus expressive) affected the perceptions of tastiness and healthiness of the food offered. Experiment 1 was carried out with 30 participants, and the results showed that participants perceived the food presented on more beautiful plates as tastier and healthier than the food on less beautiful plates. Experiment 2 was carried out with 128 participants; the results showed that, for expressively aesthetic plates, the participants experienced more positive emotions for very beautiful plates and more negative emotions for less beautiful plates. However, for classical aesthetic plates, participants’ emotions were not affected by the beauty of the plate. Experiment 3 was carried out with 149 participants, and the results showed that, for classically aesthetic plates, participants perceived the food placed in the middle to be tastier than food placed at the edge; however, for expressively aesthetic plates, food placement did not affect participants’ perceptions of food. These results demonstrate the importance of the subjective beauty of plate patterns in influencing consumers’ food perceptions, although this influence varies depending on the type of aesthetic design of the plate pattern.

Exploring the Effect of Parental Styles on Social Skills: The Mediating Role of Affects

Parental educational styles have a significant effect in personal development. These styles (authoritative, democratic, permissive and neglectful) can be related to affects and social skills at the individual level. The study presented here, which comprised 456 participants (151 men; 33.11%), with an average age of 22.01 years (s.d. = 2.80), aimed to analyse the relationship between parental styles, affects and social skills, as well as the role played by affects in the relationship between parental style and social skills. The results suggest that the constructs under study are closely related. The most common parental style is democratic. By gender, permissive styles were more often applied to women and authoritative styles to men. No significant gender differences were found in the application of democratic and neglectful parental styles. In terms of emotional support, women were found to have higher negative affect scores and men higher emotional support scores. People with parents that use democratic and permissive styles scored higher in all variables related to affects and social skills, which challenges the notion that democratic styles are the best parental styles in terms of socialisation of children. The results of the affect and social skills scales were analysed in relation to parenting styles, indicating that children educated under a democratic parental regime tend to yield higher scores in terms of social skills than children educated under any other form of parental regime and medium scores in terms of affects. Finally, it was found that parenting styles have a direct influence on social skills, which tend to improve when affects play a mediating role between these two constructs. These results suggest that parenting styles are closely related to affects and social skills. In addition, they also suggest that affects play a mediating role in the relationship between parenting styles and social skills. Finally, owing to the impact that parenting styles have on affects and social skills, more research is needed to address this issue.

Escala de Bienestar Subjetivo, versión corta (EBS-8): Revalidación, invarianza de medición y teoría de respuesta al ítem

La Escala de Bienestar Subjetivo (ebs-20) y su versión corta (ebs-8) fueron desarrolladas y validadas para medir en población hispanohablante la satisfacción con la vida y el afecto positivo. El objetivo del presente estudio fue obtener evidencias adicionales de validez para la ebs-8. Para ello, se aplicó la escala en tres estudios sucesivos a un total de 2259 mexicanos de 12 a 81 años. Los resultados del primer estudio permitieron confirmar la estructura unifactorial (cmin/df = 2.336; cfi = .996; rmsea = .047) y la adecuada confiabilidad de la escala (α = .958, ω = .957); en el segundo se probó su invarianza de medición por sexo, grupo social y edad (Δχ2 p > .05, δcfi < .004, δrmsea < .014); y en el tercer estudio se encontró, mediante la calibración de sus reactivos bajo la tri, que la escala estima satisfactoriamente el constructo evaluado (α > 1.69; β1 entre –2.78 y –2.35). A partir de los índices psicométricos obtenidos, se concluye que la ebs-8 es un excelente instrumento breve construido en español para evaluar el bienestar subjetivo en adolescentes, jóvenes, adultos y adultos mayores.

Exploratory Graph Analysis of the Strengths and Difficulties Questionnaire for Aboriginal and/or Torres Strait Islander Children

In Australia, one of the most frequently used measures for assessing social and emotional well-being (SEWB) of Aboriginal and/or Torres Strait Islander children is the Strengths and Difficulties Questionnaire (SDQ). Previous studies on state-level validations have indicated the problems associated with the original five-factor SDQ structure, especially in the dimension of Peer Problems. The aim of this study was to use a novel psychometric methodology, namely Exploratory Graph Analysis (EGA), to evaluate the dimensionality of caregiver-informant SDQ version 4-10 years at a national level in Australia. Data for this study were retrospectively collected from two independent longitudinal studies: the Longitudinal Study of Indigenous Children (LSIC) and South Australian Aboriginal Birth Cohort (SAABC). The caregiver-informed SDQ version 4-10 years was applied across several study waves, including more than 4,000 responses. To conduct EGA, Gaussian graphical models (GGMs) were estimated using the Least Absolute Shrinkage and Selection Operator. About 2,500 bootstrap samples were also employed to investigate dimensions and item stability. The findings indicated robust evidence against the construct validity of the original five-factor SDQ structure. Future studies should conduct a direct external validation of the findings with Aboriginal and/or Torres Strait Islander parents/carers and community groups to develop the guidelines for future use of the instrument among Aboriginal and/or Torres Strait Islander children in Australia.
