Interdependence is a fundamental characteristic of social interactions. Interdependence Theory states that 6 dimensions describe differences between social situations. Here we examine if these 6 ...dimensions describe how people think about their interdependence with others in a situation. We find that people (in situ and ex situ) can reliably differentiate situations according to 5, but not 6, dimensions of interdependence: (a) mutual dependence, (b) power, (c) conflict, (d) future interdependence, and (e) information certainty. This model offers a unique framework for understanding how people think about social situations compared to another recent model of situation construal (DIAMONDS). Furthermore, we examine factors that are theorized to shape perceptions of interdependence, such as situational cues (e.g., nonverbal behavior) and personality (e.g., HEXACO and Social Value Orientation). We also study the implications of subjective interdependence for emotions and cooperative behavior during social interactions. This model of subjective interdependence explains substantial variation in the emotions people experience in situations (i.e., happiness, sadness, anger, and disgust), and explains 24% of the variance in cooperation, above and beyond the DIAMONDS model. Throughout these studies, we develop and validate a multidimensional measure of subjective outcome interdependence that can be used in diverse situations and relationships-the Situational Interdependence Scale (SIS). We discuss how this model of interdependence can be used to better understand how people think about social situations encountered in close relationships, organizations, and society.

Reaction time is believed to be a good indicator of the speed and efficiency of mental processes and is a ubiquitous variable in the behavioral sciences. Despite this popularity, there are numerous ...issues associated with using reaction time (RT), specifically in differential and developmental research. Here, we identify and focus on two main problems-unreliability and sensitivity to speed-accuracy interactions. The use of difference scores is a primary factor that leads to many RT measures having demonstrably low reliability, and RT measures in general often do not properly account for speed-accuracy interactions. Both factors jeopardize the validity and interpretability of results based on RT. Here, we evaluate conceptually and empirically how these issues affect individual differences research. Although the empirical evidence we provide are primarily within the domains of attention control and task switching, we highlight examples from various other areas of psychological inquiry. We also discuss many of the statistical and methodological alternatives available to researchers conducting correlational studies. Ultimately, we encourage researchers comparing individuals of differing cognitive and developmental levels to strongly consider using these alternatives in lieu of RT, specifically RT difference scores.
Public Significance Statement
This review identifies and discusses the problems with the use of RT, particularly RT differences, in assessing how individuals differ from one another. Given these problems, a variety of conclusions and theoretical accounts stemming from RTs in individual differences studies may be misinformed. Examples include the efficacy of some clinical techniques, the measurement of racial bias, and the measurement of attention.

The Clinician-Administered PTSD Scale (CAPS) is an extensively validated and widely used structured diagnostic interview for posttraumatic stress disorder (PTSD). The CAPS was recently revised to ...correspond with PTSD criteria in the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5; American Psychiatric Association, 2013). This article describes the development of the CAPS for DSM-5 (CAPS-5) and presents the results of an initial psychometric evaluation of CAPS-5 scores in 2 samples of military veterans (Ns = 165 and 207). CAPS-5 diagnosis demonstrated strong interrater reliability (к = .78 to 1.00, depending on the scoring rule) and test-retest reliability (к = .83), as well as strong correspondence with a diagnosis based on the CAPS for DSM-IV (CAPS-IV; к = .84 when optimally calibrated). CAPS-5 total severity score demonstrated high internal consistency (α = .88) and interrater reliability (ICC = .91) and good test-retest reliability (ICC = .78). It also demonstrated good convergent validity with total severity score on the CAPS-IV (r = .83) and PTSD Checklist for DSM-5 (r = .66) and good discriminant validity with measures of anxiety, depression, somatization, functional impairment, psychopathy, and alcohol abuse (rs = .02 to .54). Overall, these results indicate that the CAPS-5 is a psychometrically sound measure of DSM-5 PTSD diagnosis and symptom severity. Importantly, the CAPS-5 strongly corresponds with the CAPS-IV, which suggests that backward compatibility with the CAPS-IV was maintained and that the CAPS-5 provides continuity in evidence-based assessment of PTSD in the transition from DSM-IV to DSM-5 criteria.
Public Significance Statement
This study evaluated the DSM-5 version of the Clinician-Administered PTSD Scale (CAPS-5), a widely used structured interview for posttraumatic stress disorder, in 2 samples of military veterans. Results indicated that the CAPS-5 is psychometrically sound and corresponds closely with the previous DSM-IV version of the CAPS.

Psychological tests typically include a response scale whose purpose it is to organize and constrain the options available to respondents and facilitate scoring. One such response scale is the Likert ...scale, which initially was introduced to have a specific 5-point form. In practice, such scales have varied considerably in the nature and number of response options. However, relatively little consensus exists regarding several questions that have emerged regarding the use of Likert-type items. First, is there a "psychometrically optimal" number of response options? Second, is it better to include an even or odd number of response options? Finally, do visual analog items offer any advantages over Likert-type items? We studied these questions in a sample of 1,358 undergraduates who were randomly assigned to groups to complete a common personality measure using response scales ranging from 2 to 11 options, and a visual analog condition. Results revealed attenuated psychometric precision for response scales with 2 to 5 response options; interestingly, however, the criterion validity results did not follow this pattern. Also, no psychometric advantages were revealed for any response scales beyond 6 options, including visual analogs. These results have important implications for psychological scale development.
Public Significance Statement
We studied several aspects of questionnaire response scales and their impact on the reliability and validity of a personality measure. We found that smaller numbers of response options have a negative impact on the measurement precision of a scale, which has important implications how psychological measures should be developed and used in practice.

We investigate the relationship of morality and political orientation by focusing on the influential results showing that liberals and conservatives rely on different moral foundations. We conducted ...a comprehensive literature search from major databases and other sources for primary studies that used the Moral Foundations Questionnaire and a typical measure of political orientation, a political self-placement item. We used a predefined process for independent extraction of effect sizes by two authors and ran both study-level and individual-level analyses. With 89 samples, 605 effect sizes, and 33,804 independent participants, in addition to 192,870 participants from the widely used YourMorals.org website, the basic differences about conservatives and liberals are supported. Yet, heterogeneity is moderate, and the results may be less generalizable across samples and political cultures than previously thought. The effect sizes obtained from the YourMorals.org data appear inflated compared with independent samples, which is partly related to political interest and may be because of self-selection. The association of moral foundations to political orientation varies culturally (between regions and countries) and subculturally (between White and Black respondents and in response to political interest). The associations also differ depending on the choice of the social or economic dimension and its labeling, supporting both the bidimensional model of political orientation and the findings that the dimensions are often strongly correlated. Our findings have implications for interpreting published studies, as well as designing new ones where the political aspect of morality is relevant. The results are primarily limited by the validity of the measures and the homogeneity of the included studies in terms of sample origins.
Public Significance Statement
This study examines the widely published results that liberals and conservatives see morality differently-that they rely on different "moral foundations." Our findings suggest that while these differences are mostly stable, they are smaller or more unpredictable outside politically interested White American samples. These differences depend on how the respondents are recruited, from which country and demographic the results are, and how political orientation is measured.

Maternal ambivalence refers to the simultaneous experience of both negative and positive feelings about motherhood and the child. It has been suggested that maternal ambivalence exists on a continuum ...from manageable (healthy) to unmanageable (problematic) and can have wide-ranging psychological consequences. However, there are currently no empirically validated measures for examining manageable or unmanageable maternal ambivalence. In this article, we outline the development and initial validation of the Maternal Ambivalence Questionnaire (MAQ). An online study was conducted to evaluate the factor structure, construct validity, reliability, and relationships of the MAQ with demographic characteristics. The participants included a community sample of 502 mothers living in the United Kingdom with at least one child aged 0-11 years. Statistical analyses demonstrated a good fit for the 20-item measure and suggested five theoretically consistent factors. These factors are assessment of one's perception of self as a mother, awareness of conflicting feelings about motherhood, suppression of negative feelings about motherhood, internalization of negative feelings about motherhood, and externalization of negative feelings about motherhood. These factors were related in theoretically expected ways to parental reflective functioning capacity, parenting stress and guilt, and symptoms of depression. The study's findings indicate that the MAQ is a robust and reliable measure that contributes to a theoretical understanding and practical assessment of maternal ambivalence, facilitating insight into emotional challenges of motherhood.

This study examined the psychometric properties of the posttraumatic stress disorder (PTSD) Checklist for Diagnostic and Statistical Manual of Mental Disorders-Fifth Edition (PCL-5; Weathers, Litz, ...et al., 2013b) in 2 independent samples of veterans receiving care at a Veterans Affairs Medical Center (N = 468). A subsample of these participants (n = 140) was used to define a valid diagnostic cutoff score for the instrument using the Clinician-Administered PTSD Scale for DSM-5 (CAPS-5; Weathers, Blake, et al., 2013) as the reference standard. The PCL-5 test scores demonstrated good internal consistency (α = .96), test-retest reliability (r = .84), and convergent and discriminant validity. Consistent with previous studies (Armour et al., 2015; Liu et al., 2014), confirmatory factor analysis revealed that the data were best explained by a 6-factor anhedonia model and a 7-factor hybrid model. Signal detection analyses using the CAPS-5 revealed that PCL-5 scores of 31 to 33 were optimally efficient for diagnosing PTSD (κ(.5) = .58). Overall, the findings suggest that the PCL-5 is a psychometrically sound instrument that can be used effectively with veterans. Further, by determining a valid cutoff score using the CAPS-5, the PCL-5 can now be used to identify veterans with probable PTSD. However, findings also suggest the need for research to evaluate cluster structure of DSM-5.

Purpose: This study attempted to develop and to preliminarily validate the Mandarin Chinese version of the Vocal Fatigue Index (VFI) as a standardized self-assessment questionnaire tool for potential ...clinical applications. Method: The experimental procedure involved (a) cross-cultural adaptation of the VFI into the Mandarin Chinese version (CVFI), (b) evaluation by an expert panel, (c) back translation, (d) pilot testing, and (e) validation of the questionnaire by three participant groups: 50 with voice disorders, 50 occupational voice users (at-risk group), and 50 with normal voice (control group). Internal consistency, test--retest reliability, content validity, and convergent validity of the CVFI were examined, and discriminatory ability (diagnostic accuracy) for distinguishing between the groups was evaluated. Results: Results showed high internal consistency (Cronbach's alpha greater than or equal to 0.8817 for the total CVFI scores for all groups), high test-retest reliability (intraclass correlation coefficients greater than or equal to 0.9072, p < 0.001 for the total CVFI scores for all groups), high content validity (total content validity index = 0.9368), and high convergent validity (Pearson r greater than or equal to 0.8155, p < 0.001 between the total CVFI scores and Factors 1 and 2 scores). Significant differences between the three groups were found in all scores. Receiver operating characteristic analysis revealed a high diagnostic accuracy for distinguishing between the disorders group and the normal group (area under the curve greater than or equal to 0.927, p < 0.001 for the total CVFI scores and Factors 1 and 2 scores), with cutoff scores of greater than or equal to 36 (total CVFI score), greater than or equal to 23.5 (Factor 1 score), greater than or equal to 7.5 (Factor 2 score), and greater than or equal to 6.5 (Factor 3 score). Conclusions: These findings suggested that the CVFI could be a reliable and valid self-assessment tool for the clinical evaluation of vocal fatigue in Mandarin Chinese-speaking populations. A full-scale validation study of the CVFI is recommended to verify these results.
Objective: This study assessed the ecological validity of the Yale Food Addiction Scale (YFAS 2.0) with ecological momentary assessment (EMA) and explored the internal consistency and convergent ...validity of a momentary food addiction scale. Method: Adults (N = 49) who met criteria for binge-eating disorder and/or food addiction (age = 34.9 ± 12.1 years; 77.1% cisgender female; 55.1% non-Hispanic White) completed online questionnaires and a 10-day EMA protocol. Analyses examined (a) associations between the YFAS 2.0 and EMA-measured variables corresponding to food addiction criteria, (b) reliability of a momentary food addiction scale (EMA-FA), and (c) concurrent associations between EMA-FA and EMA-measured negative affect, impulsivity, eating expectancies, body satisfaction, consumption of palatable food, and taste response to palatable food. Results: YFAS scores were associated with EMA-reported variables corresponding to food addiction criteria (ps < .045). The multilevel reliability for EMA-FA was adequate (ω = .75-.94). Individuals with higher EMA-FA scores reported greater negative affect, impulsivity, appetite, palatable food consumption, taste response to palatable food, and contrary to expectations, greater body satisfaction (ps < .01). Within-person effects emerged for EMA-FA predicting higher negative affect, impulsivity, likelihood of palatable food consumption, more pleasurable taste responses after consuming palatable foods, yet lower body satisfaction, appetite, and eating expectancies (ps < .01). Conclusions: Results support the ecological validity of the YFAS 2.0, and additional evidence of convergent validity and internal consistency was demonstrated for a momentary food addiction scale. This assessment of the psychometric properties of the YFAS will ultimately further its utility and relevance in the study and diagnosis of food addiction.
Public Health Significance Statement
By examining the ecological validity of the Yale Food Addiction Scale (YFAS 2.0), this study contributes to the growing body of literature on food addiction, a condition that has been linked to binge eating, psychosocial impairment, as well as obesity, a continually rising public health problem (Gearhardt et al., 2011, 2012). This topic is especially important given that obesity and dysregulated eating behaviors such as binge eating disproportionately affect those with food insecurity and individuals of lower socioeconomic status (Christensen et al., 2021). Further, by evaluating the psychometric properties of YFAS 2.0, this study provided further support for the YFAS 2.0 to be used more broadly in clinical settings to detect symptoms of food addiction in these disadvantaged populations. Finally, this study recruited a diverse sample, and we were able to explore eating behaviors that are prevalent in racial minorities and women, both subsets of people that persistently experienced social disadvantage, discrimination, and health disparities.

Awe has been theorized as a collective emotion, one that enables individuals to integrate into social collectives. In keeping with this theorizing, we propose that awe diminishes the sense of self ...and shifts attention away from individual interests and concerns. In testing this hypothesis across 6 studies (N = 2137), we first validate pictorial and verbal measures of the small self; we then document that daily, in vivo, and lab experiences of awe, but not other positive emotions, diminish the sense of the self. These findings were observed across collectivist and individualistic cultures, but also varied across cultures in magnitude and content. Evidence from the last 2 studies showed that the influence of awe upon the small self accounted for increases in collective engagement, fitting with claims that awe promotes integration into social groups. Discussion focused on how the small self might mediate the effects of awe on collective cognition and behavior, the need to study more negatively valenced varieties of awe, and other potential cultural variations of the small self.
