Validity and Reliability of a Turkish Version of the Modified Moral Sensitivity Questionnaire for Student Nurses

This study examined the validity and reliability of a Turkish version of the Modified Moral Sensitivity Questionnaire for Student Nurses (MMSQSN). After obtaining permission to adapt the MMSQSN into Turkish, the translation/back-translation method was used with expert opinions to determine content validity. Factor analysis was conducted to examine the construct validity and test–retest was performed on the questionnaire to determine reliability. Cronbach’s alpha coefficients were calculated to assess for internal consistency. Participants included 272 baccalaureate degree student nurses who took ethics lessons prior to their clinical internship. The factor analysis revealed that even though the factor structure in the original scale was the same, relevant items were categorized with similar components, and factor loads were sufficient. The correlation coefficient in the analyses of test–retest scores was .66 for the total scale (p < .05) and the Cronbach’s alpha was .73 for the total scale. The translated MMSQSN is a valid and reliable measure of ethical sensitivity in student nurses in Turkey.     

Stability of Maternal Sensitivity Across Time and Contexts with Q‐Sort Measures

This study examined stability of maternal sensitivity and efficacy of a Q‐sort measure of maternal sensitivity across time and context. Two versions of the maternal behavior Q‐set (MBQS) were employed, first during the Strange Situation Procedure (SSP) and second at home, 2.5 years later based on an available subsample. Findings revealed that the MBQS scores assessed at two time points in two contexts were significantly correlated, showing the stability of maternal sensitivity of the subsample over a time period of 2.5 years. The MBQS scores assigned to mothers of preschoolers were also significantly correlated with their children's early interactive behavioural scores given during the SSP. The current findings further support validating the consistency, the versatility and the efficacy of the MBQS as a sound measure of maternal sensitivity.

Exploring Individual and Contextual Antecedents of Attitudes Toward the Acceptability of Cheating and Plagiarism

The purpose of this study was to identify the relative contribution of individual and contextual predictors to students’ attitudes toward the acceptability of cheating and plagiarism. A group of 324 students from a tertiary institution in New Zealand completed an online survey. The findings indicate that gender, justice sensitivity, and understanding of university policies regarding academic dishonesty were the key predictors of the students’ attitudes toward the acceptability of cheating and plagiarism, both as agents of dishonest conduct and as witnesses of misconduct among their peers. The implications of these findings for the development of policies and initiatives in tertiary institutions are discussed.     

Maternal prenatal stress and infant regulatory capacity in Mexican Americans

The early postpartum period lays important groundwork for later self-regulation as infants’ dispositional traits interact with caregivers’ co-regulatory behaviors to produce the earliest forms of self-regulation. Although emerging literature suggests that fetal exposure to maternal stress may be integral in determining child self-regulatory capacity, the complex pathways that characterize these early developmental processes remain unclear. The current study considers these complex, transactional processes in a low income, Mexican American sample. Data were collected from 295 Mexican American infants and their mothers during prenatal, 6- and 12-week postpartum home interviews. Mother reports of stress were obtained prenatally, and mother reports of infant temperament were obtained at 6 weeks. Observer ratings of maternal sensitivity and infant regulatory behaviors were obtained at the 6- and 12-week time points. Study results indicate that prenatal stress predicts higher levels of infant negativity and surgency, both of which directly or interactively predict later engagement in regulatory behaviors. Unexpectedly, prenatal stress also predicted more engagement in orienting, but not self-comforting behaviors. Advancing understandings about the nature of these developmental pathways may have significant implications for targets of early intervention in this high risk population.     

Assessing Omitted Confounder Bias in Multilevel Mediation Models

To draw valid inference about an indirect effect in a mediation model, there must be no omitted confounders. No omitted confounders means that there are no common causes of hypothesized causal relationships. When the no-omitted-confounder assumption is violated, inference about indirect effects can be severely biased and the results potentially misleading. Despite the increasing attention to address confounder bias in single-level mediation, this topic has received little attention in the growing area of multilevel mediation analysis. A formidable challenge is that the no-omitted-confounder assumption is untestable. To address this challenge, we first analytically examined the biasing effects of potential violations of this critical assumption in a two-level mediation model with random intercepts and slopes, in which all the variables are measured at Level 1. Our analytic results show that omitting a Level 1 confounder can yield misleading results about key quantities of interest, such as Level 1 and Level 2 indirect effects. Second, we proposed a sensitivity analysis technique to assess the extent to which potential violation of the no-omitted-confounder assumption might invalidate or alter the conclusions about the indirect effects observed. We illustrated the methods using an empirical study and provided computer code so that researchers can implement the methods discussed.     

The Combined Effects of Measurement Error and Omitting Confounders in the Single-Mediator Model

Mediation analysis requires a number of strong assumptions be met in order to make valid causal inferences. Failing to account for violations of these assumptions, such as not modeling measurement error or omitting a common cause of the effects in the model, can bias the parameter estimates of the mediated effect. When the independent variable is perfectly reliable, for example when participants are randomly assigned to levels of treatment, measurement error in the mediator tends to underestimate the mediated effect, while the omission of a confounding variable of the mediator-to-outcome relation tends to overestimate the mediated effect. Violations of these two assumptions often co-occur, however, in which case the mediated effect could be overestimated, underestimated, or even, in very rare circumstances, unbiased. To explore the combined effect of measurement error and omitted confounders in the same model, the effect of each violation on the single-mediator model is first examined individually. Then the combined effect of having measurement error and omitted confounders in the same model is discussed. Throughout, an empirical example is provided to illustrate the effect of violating these assumptions on the mediated effect.     

How facial attractiveness affects sustained attention

The present study investigated whether and how facial attractiveness affects sustained attention. We adopted a multiple‐identity tracking paradigm, using attractive and unattractive faces as stimuli. Participants were required to track moving target faces amid distractor faces and report the final location of each target. In Experiment 1, the attractive and unattractive faces differed in both the low‐level properties (i.e., luminance, contrast, and color saturation) and high‐level properties (i.e., physical beauty and age). The results showed that the attractiveness of both the target and distractor faces affected the tracking performance: The attractive target faces were tracked better than the unattractive target faces; when the targets and distractors were both unattractive male faces, the tracking performance was poorer than when they were of different attractiveness. In Experiment 2, the low‐level properties of the facial images were equalized. The results showed that the attractive target faces were still tracked better than unattractive targets while the effects related to distractor attractiveness ceased to exist. Taken together, the results indicate that during attentional tracking the high‐level properties related to the attractiveness of the target faces can be automatically processed, and then they can facilitate the sustained attention on the attractive targets, either with or without the supplement of low‐level properties. On the other hand, only low‐level properties of the distractor faces can be processed. When the distractors share similar low‐level properties with the targets, they can be grouped together, so that it would be more difficult to sustain attention on the individual targets.     

Validation and study of psychometric properties of a French version of the Highly Sensitive Person Scale (HSPS-FR)

IntroductionThe Highly Sensitive Person Scale based on the sensory-processing sensitivity is a self-assessment questionnaire consisting of 27 items. The scale is designed in order to identify individuals with high sensitivity.ObjectiveThe objective was to develop a French version of the scale. We tested its internal consistency and test-retest reliability on a French population sample. Another aim of this study was also to question the multidimensionality of the scale, for which several different models are suggested within the literature.MethodAfter translation and back-translation, a validation study was conducted on 814 adults. They were invited to complete an online questionnaire during the lockdown implemented due to COVID 19, between March 31st and May 11th (2020).ResultsThe internal reliability of the French version of HSPS was very good, with a Cronbach's alpha of .90, as was that of the factors. Correlations between factors were significant (p < .001). The intra-class correlation (ICC) for test-retest was .889 (0.874–0.903; 95% confidence interval). Factor analyses suggested a 4-factors structure, mixing the models found in the literature.ConclusionsThis study focused on a French adaptation of the HSPS scale. The results showed good psychometric qualities and stayed true to the original HSPS scale. The scale could be useful both to practitioners in their clinical practice and to researchers in fundamental research.     

Parallel associative processing in the dorsal striatum: segregation of stimulus-response and cognitive control subregions

Although evidence suggests that the dorsal striatum contributes to multiple learning and memory functions, there nevertheless remains considerable disagreement on the specific associative roles of different neuroanatomical subregions. We review evidence indicating that the dorsolateral striatum (DLS) is a substrate for stimulus–response habit formation – incremental strengthening of simple S–R bonds – via input from sensorimotor neocortex while the dorsomedial striatum (DMS) contributes to behavioral flexibility – the cognitive control of behavior – via prefrontal and limbic circuits engaged in relational and spatial information processing. The parallel circuits through dorsal striatum interact with incentive/affective motivational processing in the ventral striatum and portions of the prefrontal cortex leading to overt responding under specific testing conditions. Converging evidence obtained through a detailed task analysis and neurobehavioral assessment is beginning to illuminate striatal subregional interactions and relations to the rest of the mammalian brain.
