The Poses for Equine Research Dataset (PFERD)

Studies of quadruped animal motion help us to identify diseases, understand behavior and unravel the mechanics behind gaits in animals. The horse is likely the best-studied animal in this aspect, but data capture is challenging and time-consuming. Computer vision techniques improve animal motion extraction, but the development relies on reference datasets, which are scarce, not open-access and often provide data from only a few anatomical landmarks. Addressing this data gap, we introduce PFERD, a video and 3D marker motion dataset from horses using a full-body set-up of densely placed over 100 skin-attached markers and synchronized videos from ten camera angles. Five horses of diverse conformations provide data for various motions from basic poses (eg. walking, trotting) to advanced motions (eg. rearing, kicking). We further express the 3D motions with current techniques and a 3D parameterized model, the hSMAL model, establishing a baseline for 3D horse markerless motion capture. PFERD enables advanced biomechanical studies and provides a resource of ground truth data for the methodological development of markerless motion capture.

Mediating role of splitting in relation to attachment styles and shopping addiction

Introduction

Shopping can provide a sense of satisfaction and pleasure; however, if a person's excessive involvement in this behavior starts to negatively impact other aspects of their life, similar to other addictive behaviors like excessive internet use, gaming, and gambling, it may be classified as pathological. Given the lack of agreement regarding the classification of excessive shopping tendencies as a separate mental health condition or addictive behavior, taking a socio-emotional approach to explore the psychological factors that precede this behavior, may offer a better comprehension of it.

Methods

The purpose of this study was to examine the relationship between attachment styles and excessive shopping behavior, as well as to investigate the potential mediating effect of defense mechanisms like splitting on this relationship. Using convenience sampling, a group of 457 stock market employees (116 female, 341 male) between the ages of 24 and 60 were recruited. The researchers utilized a set of validated psychological questionnaires to assess the employees attachment styles, shopping addiction, and splitting tendencies.

Results

The results obtained from both the mediation model and path analysis suggest that attachment styles do not have a direct relationship with shopping addiction. Nonetheless, the study supports the impact of insecure anxious and avoidan attachment styles on splitting. Furthermore, the findings confirm that splitting has a mediating effect on the relationship between attachment styles and splitting.

Discussion

The present study enhanced our comprehension of the subconscious mechanisms underlying shopping tendencies. Specifically, the findings suggest that excessive tendencies towards shopping can be considered a maladaptive response resulting from insecure attachment styles and the unconscious utilization of the splitting defense mechanism.

Recollections of Childhood Sexual Abuse: Complexities of Religious Coping and Muslim Religious and Psychological Adjustment in Afghanistan

Religious coping is a double-edged sword. Clarification of the psychological benefits for positive religious coping requires statistical controls for negative religious coping and vice versa. This study sought to further explore the complexities of Muslim religious coping by extending the analysis to Afghans who coped with the sufferings associated with recollections of childhood and adolescent sexual abuse. Two hundred Dari Persian-speaking Afghan university students (122 identified having experience of childhood sexual abuse) self-reported on variables that measure religious orientation, religious coping, Muslim experiential religiousness, mental health, and child abuse. Results showed that negative religious coping interfered with the possibly beneficial effects of positive religious coping on mental health and child abuse. After controlling for negative religious coping, the associations of positive religious coping became obvious. In addition, Muslim spirituality moderated the associations of religious coping with mental health outcomes and child abuse: for people with higher Muslim spirituality, positive religious coping associated with better mental health, and negative religious coping associated with less child abuse. Implications for religious coping and combating trauma in a religious context are discussed.

Circulatory efficiency in patients with severe aortic valve stenosis before and after aortic valve replacement

BACKGROUND

Circulatory efficiency reflects the ratio between total left ventricular work and the work required for maintaining cardiovascular circulation. The effect of severe aortic valve stenosis (AS) and aortic valve replacement (AVR) on left ventricular/circulatory mechanical power and efficiency is not yet fully understood. We aimed to quantify left ventricular (LV) efficiency in patients with severe AS before and after surgical AVR.

METHODS

Circulatory efficiency was computed from cardiovascular magnetic resonance (CMR) imaging derived volumetric data, echocardiographic and clinical data in patients with severe AS (n = 41) before and 4 months after AVR and in age and sex-matched healthy subjects (n = 10).

RESULTS

In patients with AS circulatory efficiency was significantly decreased compared to healthy subjects (9 ± 3% vs 12 ± 2%; p = 0.004). There were significant negative correlations between circulatory efficiency and LV myocardial mass (r = - 0.591, p < 0.001), myocardial fibrosis volume (r = - 0.427, p = 0.015), end systolic volume (r = - 0.609, p < 0.001) and NT-proBNP (r = - 0.444, p = 0.009) and significant positive correlation between circulatory efficiency and LV ejection fraction (r = 0.704, p < 0.001). After AVR, circulatory efficiency increased significantly in the total cohort (9 ± 3 vs 13 ± 5%; p < 0.001). However, in 10/41 (24%) patients, circulatory efficiency remained below 10% after AVR and, thus, did not restore to normal values. These patients also showed less reduction in myocardial fibrosis volume compared to patients with restored circulatory efficiency after AVR.

CONCLUSION

In our cohort, circulatory efficiency is reduced in patients with severe AS. In 76% of cases, AVR leads to normalization of circulatory efficiency. However, in 24% of patients, circulatory efficiency remained below normal values even after successful AVR. In these patients also less regression of myocardial fibrosis volume was seen.

Self-Compassion and Cultural Values: A Cross-Cultural Study of Self-Compassion Using a Multitrait-Multimethod (MTMM) Analytical Procedure

Self-compassion is natural, trainable and multi-faceted human capacity. To date there has been little research into the role of culture in influencing the conceptual structure of the underlying construct, the relative importance of different facets of self-compassion, nor its relationships to cultural values. This study employed a cross-cultural design, with 4,124 participants from 11 purposively sampled datasets drawn from different countries. We aimed to assess the relevance of positive and negative items when building the self-compassion construct, the convergence among the self-compassion components, and the possible influence of cultural values. Each dataset comprised undergraduate students who completed the “Self-Compassion Scale” (SCS). We used a confirmatory factor analysis (CFA) approach to the multitrait-multimethod (MTMM) model, separating the variability into self-compassion components (self-kindness, common humanity, mindfulness), method (positive and negative valence), and error (uniqueness). The normative scores of the Values Survey Module (VSM) in each country, according to the cultural dimensions of individualism, masculinity, power distance, long-term orientation, uncertainty avoidance, and indulgence, were considered. We used Spearman coefficients (r_s) to assess the degree of association between the cultural values and the variance coming from the positive and negative items to explain self-compassion traits, as well as the variance shared among the self-compassion traits, after removing the method effects produced by the item valence. The CFA applied to the MTMM model provided acceptable fit in all the samples. Positive items made a greater contribution to capturing the traits comprising self-compassion when the long-term orientation cultural value was higher (r_s = 0.62; p = 0.042). Negative items did not make significant contributions to building the construct when the individualism cultural value was higher, but moderate effects were found (r_s = 0.40; p = 0.228). The level of common variance among the self-compassion trait factors was inversely related to the indulgence cultural value (r_s = -0.65; p = 0.030). The extent to which the positive and negative items contribute to explain self-compassion, and that different self-compassion facets might be regarded as reflecting a broader construct, might differ across cultural backgrounds.

Examining the factor structure of the Self-Compassion Scale in 20 diverse samples: Support for use of a total score and six subscale scores

This study examined the factor structure of the Self-Compassion Scale (SCS) using secondary data drawn from 20 samples (N = 11,685)-7 English and 13 non-English-including 10 community, 6 student, 1 mixed community/student, 1 meditator, and 2 clinical samples. Self-compassion is theorized to represent a system with 6 constituent components: self-kindness, common humanity, mindfulness and reduced self-judgment, isolation and overidentification. There has been controversy as to whether a total score on the SCS or if separate scores representing compassionate versus uncompassionate self-responding should be used. The current study examined the factor structure of the SCS using confirmatory factor analyses (CFA) and Exploratory Structural Equation Modeling (ESEM) to examine 5 distinct models: 1-factor, 2-factor correlated, 6-factor correlated, single-bifactor (1 general self-compassion factor and 6 group factors), and 2-bifactor models (2 correlated general factors each with 3 group factors representing compassionate or uncompassionate self-responding). Results indicated that a 1- and 2-factor solution to the SCS had inadequate fit in every sample examined using both CFA and ESEM, whereas fit was excellent using ESEM for the 6-factor correlated, single-bifactor and correlated 2-bifactor models. However, factor loadings for the correlated 2-bifactor models indicated that 2 separate factors were not well specified. A general factor explained 95% of the reliable item variance in the single-bifactor model. Results support use of the SCS to examine 6 subscale scores (representing the constituent components of self-compassion) or a total score (representing overall self-compassion), but not separate scores representing compassionate and uncompassionate self-responding.

Religious and Psychological Implications of Positive and Negative Religious Coping in Iran

This study examined the religious and psychological implications of religious coping in Iran. University students (N = 224) responded to the Brief Positive and Negative Religious Coping Scales along with measures of Religious Orientation, Integrative Self-Knowledge, Self-Control, Mindfulness, Self-Compassion, Self-Esteem, Guilt, Shame, and Self-Criticism. As in previous research elsewhere, Positive Religious Coping was stronger on average than Negative Religious Coping, and Positive and Negative Religious Coping predicted adjustment and maladjustment, respectively, In addition, this study demonstrated that direct relationships between Positive and Negative Religious Coping appeared to be reliable in Iran; that Positive Religious Copings was broadly compatible with, and Negative Religious Coping was largely irrelevant to, Iranian religious motivations; and that Negative Religious Coping obscured linkages of Positive Religious Coping with religious and psychological adjustment.

Relationship of Self-Reported Mysticism with Depression and Anxiety in Iranian Muslims

This study examined relationships of self-reported Mysticism with dispositional Depression and Anxiety in Iranian Muslims. The sample contained 80 women and 51 men undergraduates who volunteered to participate ( M age = 20.5 yr., SD = 2.0). Participants responded to the Hood Mysticism Scale and to the Costello and Comrey Depression and Anxiety Scales. Scores on the Religious Interpretation dimension of mystical experience correlated negatively with those on Depression, explained a similar relationship observed for Extrovertive Mysticism, and moderated the otherwise positive relationship between Introvertive Mysticism and Anxiety. Moderation occurred when Introvertive Mysticism correlated negatively rather than positively with Anxiety in those who scored high on Religious Interpretation and very high on the Introvertive factor. These data suggested possibilities for reconciling conflicts that have appeared between philosophical interpretations of Introvertive Mysticism and previous self-report data.

Relationships of Experiential and Reflective Self-Knowledge with Trait Meta-Mood Scale, Constructive Thinking Inventory, and the Five Factors in Iranian Managers

The purpose of this study was to examine the validity and the incremental validity of recently developed Reflective and Experiential Self-knowledge Scales. Along with measures of the Five Factors and of psychological adjustment, 201 male Iranian managers responded to the Self-knowledge Scales along with tests relevant to emotional intelligence, including the Trait Meta-mood Scale and the Constructive Thinking Inventory. As hypothesized, Self-knowledge Scales predicted greater self-reported emotional intelligence. Multiple regression also confirmed the incremental validity of these scales, showed each explained a separate source of variance, and supported the presumed temporal dynamics that theoretically underlie these constructs.

Constructive Thinking Inventory: Evidence of Validity among Iranian Managers

This study examined the validity and incremental validity of the Constructive Thinking Inventory in a sample of Iranian managers. These 159 men were 39.9 yr. old ( SD = 2.5) and volunteered to participate in a project in which they responded to the Constructive Thinking Inventory, the Big Five Factors, the Costello and Comrey Depression and Anxiety Scales, and the Perceived Stress Scale. Numerous findings confirmed the validity of the Constructive Thinking Inventory, and the Global Constructive Thinking subscale displayed incremental validity. These data supported the validity of the Constructive Thinking Inventory and its associated theoretical assumptions in a sample of Iranian managers.

Hardiness Scales in Iranian Managers: Evidence of Incremental Validity in Relationships with the Five Factor Model and with Organizational and Psychological Adjustment

This study examined the incremental validity of Hardiness scales in a sample of Iranian managers. Along with measures of the Five Factor Model and of Organizational and Psychological Adjustment, Hardiness scales were administered to 159 male managers ( M age = 39.9, SD = 7.5) who had worked in their organizations for 7.9 yr. ( SD = 5.4). Hardiness predicted greater Job Satisfaction, higher Organization-based Self-esteem, and perceptions of the work environment as being less stressful and constraining. Hardiness also correlated positively with Assertiveness, Emotional Stability, Extraversion, Openness to Experience, Agreeableness, and Conscientiousness and negatively with Depression, Anxiety, Perceived Stress, Chance External Control, and a Powerful Others External Control. Evidence of incremental validity was obtained when the Hardiness scales supplemented the Five Factor Model in predicting organizational and psychological adjustment. These data documented the incremental validity of the Hardiness scales in a non-Western sample and thus confirmed once again that Hardiness has a relevance that extends beyond the culture in which it was developed.

Investigating the Properties of the General Factor (M) in Bifactor Models Applied to Big Five or HEXACO Data in Terms of Method or Meaning

This project applied a bifactor model, which specifies a general factor that accounts for the common variance among all scale items, and group factors that reflect additional common variance among clusters of items. This general factor is designated as “M” because of a presumption in the research literature that its origins are to be found in method. The model was applied in eight samples using nine datasets and across three different personality measures, including the Big Five and the HEXACO. Inclusion of M significantly increased model fit and increased the variance explained of items. Evidence showed that M did not reflect aspects of method such as random error or an acquiescent response bias. M correlated positively with variables suggesting psychological adjustment and negatively with variables pointing toward maladjustment. M showed unique relationships with constructs suggesting psychological adjustment over and beyond the Big Five. Data supported an interpretation of M as a synthesizing function within the self and thus suggested that M was a construct revealing substantive psychological meaning rather than mere method.

Replacing corn with pearl millet (raw and sprouted) with and without enzyme in chickens' diet

An experiment was conducted to compare a commercial corn-soya bean meal diet with a pearl millet (raw and sprouted) diet containing less soya bean meal, alone or in combination with exogenous enzyme, on growth performance and ileal villus development of chicks. Two-hundred-and-forty-one-day-old male broilers (10/pen) were randomly allocated to one of the following dietary treatments: (i) a standard corn-soya bean meal control diet (CTL); (ii) a raw pearl millet-soya bean meal diet (PM); (iii) a sprouted pearl millet-soya bean meal diet (SPM); (iv) CTL + exogenous enzymes (CE); (v) PM + exogenous enzymes (PE); and (vi) SPM + exogenous enzymes (SPE) with four replicate pens/treatment. Body weight of birds at day 21 did not differ between those fed the CTL, and SPM and PE diets. In comparison with feeding broilers the CTL diet, feeding the PE and SPM diets caused significant decrease in feed intake, but with equivalent growth and feed efficiency. However, at day 21, feed conversion ratio did not differ between birds fed the CTL diet and those fed the PM, PE and SPM diets. At day 21, broilers fed the PM and PE diets had longer villi (p < 0.05) than those fed the CTL diet. At day 21, villi width was reduced (p < 0.05) by raw pearl millet supplementation than CTL diet. It is concluded that, in comparison with corn, broiler diets formulated with sprouted pearl millet or pearl millet with enzyme require less soya bean meal and can be used to improve growth performance traits and villus development.

Comparison of anger management, anxiety and perceived stress in patients with cancer and Coronary Heart Disease (CHD)

The present study was conducted with the aim of studying the comparison of anger management, anxiety and perceived stress in patients with cancer and Coronary Heart Disease (CHD). The two groups of subjects consisted of patients with cancer (n = 120) and patients with CHD (n = 118) who were selected by using a convenience sampling method and by the employment of Spielberger's State-Trait Anger Expression, Costello and Camry Depression and Anxiety scale and Perceived Stress Scale of Cohen, Kamarak and Mermelstein. In order to analyze the data, after the calculation of descriptive statistics and correlation coefficients, MONOVA was employed to test the hypotheses. The findings indicated that patients with CHD regulate the excitement by externalizing anger and patients with cancer control this excitement by internalizing anger. Moreover, stress and depression in patients with CHD were greater than in patients with cancer. The findings were explained by the employment of the theoretical patterns of the mediating role of personality and regulation of excitement in stress and illness.

Integrative self-knowledge and marital satisfaction

Married Iranian couples (N = 210) responded to the Integrative Self-Knowledge Scale along with a measure of marital satisfaction, the International Personality Item Pool (IPIP) Big Five, and an index of interpersonal problems. Integrative self-knowledge correlated positively with marital satisfaction, positively with all but the extraversion Big Five traits, and negatively with three indices of interpersonal problems. Integrative self-knowledge also mediated a number of personality relationships with marital satisfaction. Spouse-ratings of personality confirmed the adaptive implications of integrative self-knowledge for marriage. Linkages with questionnaire response styles supported the description of integrative self-knowledge as a measure of both self-insight and self-development. Results confirmed the potential of integrative self-knowledge for studying self-regulatory processes and suggested that the enhancement of self-knowledge may be a useful goal in efforts to strengthen marriages.

A multi-process model of self-regulation: influences of mindfulness, integrative self-knowledge and self-control in Iran

Self-regulation presumably rests upon multiple processes that include an awareness of ongoing self-experience, enduring self-knowledge and self-control. The present investigation tested this multi-process model using the Five-Facet Mindfulness Questionnaire (FFMQ) and the Integrative Self-Knowledge and Brief Self-Control Scales. Using a sample of 1162 Iranian university students, we confirmed the five-factor structure of the FFMQ in Iran and documented its factorial invariance across males and females. Self-regulatory variables correlated negatively with Perceived Stress, Depression, and Anxiety and positively with Self-Esteem and Satisfaction with Life. Partial mediation effects confirmed that self-regulatory measures ameliorated the disturbing effects of Perceived Stress. Integrative Self-Knowledge and Self-Control interacted to partially mediate the association of Perceived Stress with lower levels of Satisfaction with Life. Integrative Self-Knowledge, alone or in interaction with Self-Control, was the only self-regulation variable to display the expected mediation of Perceived Stress associations with all other measures. Self-Control failed to be implicated in self-regulation only in the mediation of Anxiety. These data confirmed the need to further examine this multi-process model of self-regulation.

Relationship of perceived stress with depression: complete mediation by perceived control and anxiety in Iran and the United States

This study sought to clarify the importance and cross-cultural relevance of associations between generalized perceived stress and depression. Also tested was the hypothesis that perceived stress would correlate more strongly with anxiety than with depression, whereas control would be more predictive of depression than of anxiety. Relationships between perceived stress, anxiety, depression, and perceived control were examined in samples of Iranian (n = 191) and American (n = 197) undergraduates. Correlations among these variables were generally similar across the two societies. Perceived stress did predict anxiety better than depression, but perceptions of control predicted depression significantly better than anxiety only in the United States. Best fitting structural equation models revealed that anxiety and perceived control completely accounted for the linkage between perceived stress and depression in both societies. An equally acceptable and more parsimonious model described perceived stress as a consequence rather than as an antecedent of anxiety and perceived control. Structural equation models were essentially identical across the two cultures except that internal control displayed a significant negative relationship with anxiety only in Iran. This result seemed to disconfirm any possible suggestion that a supposedly individualistic process like internal control could have no noteworthy role within a presumably more collectivistic Muslim society like Iran. Overall, these data documented the importance of anxiety and perceived control in explaining the perceived stress-depression relationship cross-culturally and therefore questioned the usefulness of perceived stress in predicting depression. Whether this understanding of the stress-depression relationship deserves general acceptance will require additional studies that measure the frequency of stressful life events and that utilize a longitudinal design.

Validity of Experiential and Reflective Self-knowledge Scales: relationships with basic need satisfaction among Iranian factory workers

This study examined the validity of Experiential and Reflective Self-knowledge Scales in a sample of Iranian factory workers. Both scales were administered to 321 male and 12 female workers (M age= 35.6 yr., SD= 8.9) along with the Basic Need Satisfaction at Work Scales, the Work Climate Questionnaire, and measures of Perceived Stress and Self-esteem. Scores on the two self-knowledge measures correlated with all other variables consistent with the claim of Self-determination Theory that self-insight is associated with a more complete satisfaction of basic needs. In a number of multiple regression analyses, Reflective and Experiential Self-knowledge combined to explain variance in other measures. These data further supported the validity of the two new Self-knowledge Scales.

Philosophy, Self-Knowledge, and Personality in Iranian Teachers and Students of Philosophy

Like psychology, philosophy apparently operates from a commitment to the belief that self-knowledge should be a goal of disciplinary and personal development. Iranian teachers and students of philosophy responded to a Philosophical Orientations Scale created for this study that assessed the possible content of a high school philosophy course, along with instruments measuring self-knowledge, need for cognition, the five-factor model, anxiety, depression, and perceived stress. As the authors hypothesized, self-knowledge predicted higher levels of a philosophical orientation, even after controlling for the variance explained by need for cognition and openness to experience. Philosophical orientations and self-knowledge were also correlated with psychological adjustment, and teachers scored higher than students on these two sets of constructs. These data supported the hypothesis that personal and disciplinary interests in an adaptive self-knowledge converge in philosophy.

Private Self-Consciousness Factors: Relationships With Need for Cognition, Locus of Control, and Obsessive Thinking in Iran and the United States

The authors measured Internal State Awareness (ISA) and Self-Reflectiveness (SR) factors from the Private Self-Consciousness Scale in Iranian (N = 325) and U.S. (N = 401) university students. In both societies, positive correlations with Need for Cognition and Internal Control and negative correlations with external control and obsessive thinking confirmed ISA as an adaptive form of self-consciousness. In partial correlations in which the authors controlled for ISA, SR was associated cross-culturally with greater Obsessive Thinking. This outcome conformed with the authors' expectations that SR would have negative mental health implications, but other data revealed complexities in the SR association with adjustment. Differences between samples failed to yield any simple support for F. Fukuyama's (1992) suggestion that Iranians might be more "alienated" (pp. 236-237) in their psychological functioning. The present study most importantly offered cross-cultural evidence in favor of the claim that better measures of an introspective self-awareness need to be developed.

TWO FACETS OF SELF-KNOWLEDGE, THE FIVE-FACTOR MODEL, AND PROMOTIONS AMONG IRANIAN MANAGERS

Reflective and Experiential Self-Knowledge Scales were administered to Iranian managers along with measures of the Five Factor Model, anxiety, depression, perceived stress, and attributional complexity. Experiential Self-Knowledge correlated positively with the number of promotions earned by these managers. Both scales were associated with higher levels of Agreeableness, Openness to Experience, and Extraversion and, in general, with greater self-reported mental health. Each Self-Knowledge Scale displayed evidence of incremental validity. These data confirmed that the Reflective and Experiential Self-Knowledge Scales deserve additional research attention.

Two facets of self-knowledge: cross-cultural development of measures in Iran and the United States

Self-knowledge is an ideal not only within psychological theory and practice but also within the religious and philosophical foundations of many cultures. In 6 studies conducted in Iran and the United States, the authors sought to construct and to validate scales for measuring two facets of self-knowledge. Experiential self-knowledge was defined as an ongoing sensitivity to the self in the present. Reflective self-knowledge was described in terms of personal efforts to integrate experience within self-schemas developed in the past. Thirteen-item experiential self-knowledge and reflective self-knowledge scales were created by the authors using samples of Iranian and American university students. A confirmatory factor analysis verified this 2-factor structure in a second study, and these results were replicated in a 3rd study. Correlations with a broad array of self-report variables established the two scales as valid measures of adjustment. Both displayed adequate test-retest reliability. Correlations with peer reports suggested that the two factors had behavioral implications in both cultures. Reflective self-knowledge proved to be as important as educational abilities in predicting the academic performance of Americans who were motivated to attend class. Experiential self-knowledge and reflective self-knowledge also interacted to predict better grades. In short, the experiential self-knowledge and reflective self-knowledge scales operationalized cross-cultural personality processes that deserve additional research attention.
