Electrocortical correlates of hypersensitivity to large immediate rewards in sensation seeking.

Sensation seeking and delay discounting are strong predictors of various risk-taking behaviors. However, the relationship between sensation seeking and delay discounting remains elusive. Here, we addressed this issue by examining how high sensation seekers (HSS; N = 40) and low sensation seekers (LSS; N = 40) evaluated immediate and delayed rewards with low and high amounts during a behavioral task and an EEG task of delay discounting. Although HSS and LSS exhibited comparable discounting preference at the behavioral level, HSS relative to LSS was associated with a greater delay discounting effect at the neural level when earned rewards were large. This abnormality of reward magnitude was further corroborated by an electrocortical hypersensitivity to large immediate rewards and a stronger neural coding of reward magnitude for HSS as compared to LSS. Our findings support both the hyperactive approach theory and the optimal arousal theory in sensation seeking and have implications for the prevention and intervention targeting sensation seeking to reduce maladaptive risk-taking behaviors.

The Emotion Regulation Questionnaire for Children and Adolescents (ERQ-CA): Factor Structure and Measurement Invariance in a Chinese Student Samples.

The present study aimed to examine the factor structure and measurement invariance of the Emotion Regulation Questionnaire for children and adolescents (ERQ-CA) in Chinese youth (N = 484, Mage = 10.43, SDage = .88). Three versions (i.e., ERQ-CA-10, ERQ-CA-9, and ERQ-CA-8) of the ERQ-CA were tested and compared using confirmatory factor analysis, measurement invariance, and correlation analysis. Results showed that the eight-item version of the ERQ-CA (ERQ-CA-8) fit the data best in all conditions. However, measurement invariance across gender and after a one-year retest interval was achieved using all three versions of the measurement. The three ERQ-CA versions exhibited similar patterns of correlates with external measures (i.e., perceived parental marital conflict, r = -.17 to -.20, ps < .001, emotion expression, and callous-unemotional traits, r = -.26 to -.29, p < .001). Furthermore, the ERQ-CA-10 (i.e., the original ERQ-CA) showed better reliability than the other two versions. In conclusion, although further validity studies are needed, our findings suggest that the original ERQ-CA as well as the ERQ-CA-8 both have good psychometric properties and can be used to measure emotion regulation strategies in Chinese youth.

Refining the Parenting Stress Index-Short Form (PSI-SF) in Chinese Parents.

The Parenting Stress Index-Short Form (PSI-SF) is a popular brief assessment of parenting stress. However, its latent structure and psychometric properties have not been extensively addressed, in particular in non-Western cultures. The present study is the first to examine the factor structure and psychometric properties of the PSI-SF in parents from Mainland China (683 mother-father dyads; mean age of mothers = 37.10 years, SD = 3.68; mean age of fathers = 39.81 years, SD = 4.13). Initial analyses revealed that previously proposed factor structure of the PSI-SF did not fit the data well. Exploratory and confirmatory factor analyses were then conducted to develop a psychometrically sound and efficient abbreviated version of the PSI-SF. In this new version of 15 items (PSI-SF-15), there are three factors (i.e., parental distress, parent-child dysfunctional interaction, and difficult child). This abbreviated scale showed strict measurement invariance across sex of parent and satisfactory internal consistency. The convergent validity of the PSI-SF-15 were supported by its expected relations with the original PSF-SF measures, the multitrait-multimethod procedure, and its expected relations with scores on parenting behavior, parental depressiveness, and children's conduct problems. In conclusion, these results suggest that the PSI-SF-15 is a valid measure of parenting stress in Chinese parents, and that it holds promise as an informative and reliable alternative to the original PSI-SF when administration time is limited.

Factor Structure and Construct Validity of the Youth Psychopathic Traits Inventory and Its Shorten Version in Chinese Detained Boys.

The Youth Psychopathic Traits Inventory (YPI) was designed to assess psychopathic traits in adolescents. However, there exists limited evidence for the factor structure and psychometric properties of the YPI when used with Chinese detained juveniles. The present study aimed to examine the factor structure and construct validity of the YPI and its shortened version (YPI-S) in a sample of 607 Chinese 14- to 22-year-old detained boys (M = 17.15, SD = 1.09). Confirmatory factor analyses revealed a bifactor model which best fit the data at the subscale level for the YPI, and at the item level for the YPI-S. The internal consistency of the YPI and YPI-S scores ranged from marginal to good. Both the YPI and YPI-S total and factor scores correlated positively with the APSD, an alternative psychopathic measure, as well as with proactive and reactive aggression, and correlated negatively with affective and cognitive empathy. Overall, the YPI and YPI-S are shown to be practical and valid assessment tools to measure psychopathic traits in Chinese detained youths.

Assessing Callous-Unemotional Traits in Chinese Detained Boys: Factor Structure and Construct Validity of the Inventory of Callous-Unemotional Traits.

The Inventory of Callous-Unemotional Traits (ICU) was designed to evaluate multiple facets of Callous-Unemotional (CU) traits in youths. However, no study has examined the factor structure and psychometrical properties of the ICU in Chinese detained juveniles. The current study assesses the factor structure, internal consistency and convergent validity of the ICU in 613 Chinese detained boys. Confirmatory factor analysis results indicated that the original three-factor model with 24 items showed an unacceptable fit to the data, however, the 11-item shortened version of the ICU (ICU-11) with callousness and uncaring dimensions showed the best fit. Moreover, the ICU-11 total score and factor scores had good and acceptable internal consistencies. The convergent and criterion validity of the ICU-11 was demonstrated by comparable and significant associations in the expected direction with relevant external criteria (e.g., psychopathy, aggression, and empathy). In conclusion, present findings indicated that the ICU-11 is a reliable and efficient instrument to replace the original ICU when assessing CU traits in the Chinese male detained juvenile sample.

Assessing construct validity of the Grit-S in Chinese employees.

This research examined the psychometric properties and construct validity of the Short Grit Scale (Grit-S) in Chinese insurance employees (N = 2,363; 37% males; mean age = 35.14). Exploratory factor analysis and confirmatory factor analysis (CFA) were used to determine the factor structure of the Grit-S. The resulting model was tested by multi-group CFA for the factorial invariance of the Grit-S across genders and age groups. Results showed that the Grit-S could be best explained by a two-factor model containing consistency of interest (α = .70) and perseverance of effort (α = .75). The factor model was equivalent across genders and age groups. The scores of the Grit-S were significantly correlated with external criteria variables including mental wellbeing and job performance. Overall, our findings suggested that the Grit-S can be a promising assessment of the grit trait in Chinese employees.

Psychometric Properties and Measurement Invariance of the Brief Symptom Inventory-18 Among Chinese Insurance Employees.

This study aimed to examine the psychometric properties and factorial invariance of the Brief Symptom Inventory-18 (BSI-18). Confirmatory factor analyses (CFAs) were performed to verify the BSI-18's factor structure in a large sample of Chinese insurance professionals (N = 2363, 62.7% women; age range = 19-70). Multigroup CFA were performed to test the measurement invariance of the model with the best fit across genders. In addition, structural equation modeling was conducted to test the correlations between the BSI-18 and two covariates - social support perception and grit trait. Results indicated that the bi-factor model best fit the data and was also equivalent across genders. The BSI-18's general factor, and somatization and depression dimensions were significantly related to social support perception and grit trait, whereas the anxiety dimension was not. Overall, our findings suggested that the BSI-18's can be a promising tool in assessing general psychological distress in Chinese employees.
