The Influence of Muslim and Christian Destinations on Tourists' Behavioural Intentions and Risk Perceptions

This paper studies the factors that influence tourists' risk perceptions of various destinations with different attributes and sociocultural profiles. Factor analysis is utilised to investigate the determinants of risk perceptions, finding that they are influenced both by the type of risk (delinquency, health, accident, environment and catastrophe) and by the characteristics of the destination regarding the management of risk. Structural equations modelling is conducted to study the relationships between risk perceptions, destination image and visiting intentions across destinations. Multi-group analysis across different destinations proves that tourists' risk perceptions have different influences on destination image and visiting intentions. The results show that there are significant differences according to the predominant religion at the destinations, i.e., Muslin and Christian. The implication is that different dimensions of perceived risks and destination socio-culture contexts have different influences on the behaviour of tourists.

Do Subjects from Different Occupational Groups Experience Dental Fear and Anxiety Equally?

Background and Objectives: Research into the relationship between occupation and dental fear and anxiety (DFA) is scarce. This exploratory study aimed to compare the level of DFA and its association with its predictors amongst adults from different occupational groups. Materials and Methods: A cross-sectional study with 422 respondents from four occupational groups (physicians, teachers, industry workers, and artists) was carried out. A questionnaire on previous dental experience using the Dental Anxiety Scale (DAS), Dental Fear Survey (DFS), and Self-Esteem Scale was self-administered electronically. The data analysis involved descriptive statistics and structural equation modeling (SEM). Results: The DFA levels differed significantly across the occupational groups, with the lowest mean scores among physicians (DAS = 9.29 (SE 0.39); DFS-1 = 14.67 (0.63); DFS-2 = 33.94 (1.69)) and the highest mean scores among artists (DAS = 10.74 (0.38); DFS-1 = 17.19 (0.71); DFS-2 = 41.34 (1.92)). A significant impact of self-esteem on DFA was observed among physicians, teachers, and artists, but not among industry workers. Multi-group analysis with SEM revealed differences in the variable association (Chi-squared = 53.75; df = 21; p < 0.001), thus rejecting the hypothesis of the same mechanism underlying DFA across occupational groups. Conclusions: Individuals from various occupations experience DFA at different levels, and there are different mechanisms underlying their DFA. These findings can provide valuable insights for dental practitioners in developing tailored approaches to reduce the feeling of DFA of their patients.

Interpersonal behaviors in sports context: Spanish adaptation and measurement invariance

Introduction

The interpersonal behavior questionnaire (IBQ) is an instrument that measures support and thwarting interpersonal behaviors based on the self-determination theory (SDT). The aim of this work was to adapt the IBQ to the Spanish spoken in Mexico and to examine its psychometric properties (structural validity, discriminant validity, composite reliability, factorial invariance, and nomological validity) in a sample of athletes.

Methods

For this purpose, 472 athletes (average age 17.15 years; SD = 1.47) completed a question booklet.

Results and discussion

Confirmatory factor analysis supported the structure of six related factors, three factors of behaviors that support autonomy, competence, and relatedness, and three factors of behaviors that thwarting them. The internal consistency of each factor was also supported, as well as the average variance extracted. However, the discriminant validity between the factors of competence and relatedness in their dimensions of support, on the one hand, and thwarting, on the other, is questioned. Factorial invariance was confirmed across gender (men and women) and sport type (individual and team). Nomological validity is in accordance with theory and empirical literature. More studies of the IBQ in sport are necessary to see if these results are a fortuitous product or if they manifest themselves consistently.

The Effects of General Listening Anxiety and Listening Test Anxiety on Self-Perceived Listening Performance Among Chinese English Learners

Purpose

This research seeks to conceptualize foreign language listening anxiety (FLLA) and provide its measurement, and further explore the influences of FLLA on self-perceived listening performance.

Methods

In Study 1, semi-structured interviews explored FLLA-arousal situations. Follow-up reliability and validity tests for the newly-developed scale were testified. In Study 2, structural equation modeling explored the relationship between FLLA and self-perceived performance, which was followed by the comparison of the effects of different types of FLLA on self-perceived performance between English and non-English major students.

Results

The componential factors of FLLA included two factors, namely general listening anxiety and listening test anxiety, and general listening anxiety was represented by FLLA in classroom, daily usage, and media learning. The results also showed that listening test anxiety negatively affected self-perceived performance; general listening anxiety positively affected listening test anxiety but did not affect self-perceived performance, and listening test anxiety played a full mediation role. Moreover, findings revealed that non-English major students' general listening anxiety was higher than that of English major students. However, the multi-group analysis showed that these two groups did not differ in the effect of general listening anxiety on listening test anxiety, and in the effects of listening anxieties on self-perceived performance. For the two groups, the mechanism of anxiety-and-performance relationship was consistent.

Conclusion

The results of this research have expanded the knowledge of listening anxiety by distinguishing general listening anxiety from listening test anxiety. Moreover, by testifying the mediator of listening test anxiety, this research deepened the understanding of the effects of different types of FLLA on self-perceived listening performance and the intensity differences of listening anxieties in English and non-English majors. Furthermore, the research has contributed to the literature on FLLA research based on Complex Dynamic Systems Theory, and has practical pedagogical implications for future studies.

Longitudinal relationship between depression and antisocial behaviors in Korean adolescents

Background

It is well known that depression and delinquency in adolescents are highly correlated, but longitudinal studies on the causal relationship between them are not active in East Asia compared to in Western culture. In addition, even the results of research on causal models and sex differences are inconsistent.

Objectives

This study examines the longitudinal reciprocal effects between depression and delinquent behavior in Korean adolescents based on sex differences.

Methods

We conducted multiple-group analysis by using an autoregressive cross-lagged model (ACLM). Longitudinal data from 2,075 individuals (2011-2013) were used for analysis. The longitudinal data are from the Korean Children and Youth Panel Survey (KCYPS), and data were used beginning with students at 14 years old (in the second grade of middle school) and tracked them until they were 16 (in the first grade of high school).

Results

Boys' delinquent behaviors at 15 years (the third grade of middle school) affected their depression at 16 years (the first grade of high school). In contrast, girls' depression at 15 years (the third grade of middle school) influenced their delinquent behaviors at 16 years (the first grade of high school).

Discussion

The findings support the failure model (FM) among adolescent boys and the acting-out model (ACM) among girls. The results imply that strategies to effectively prevent and treat delinquency and depression in adolescents must consider sex effects.

Before and during the COVID-19 Pandemic, Physical Fitness Association with Mental Health among Higher Education Students: A Multi-Group Analysis Model

The coronavirus disease 2019 (COVID-19) pandemic, caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), created a significant problem people's health around the world. The mental and physical health of entire populations has been negatively impacted due to the introduction of several restriction methods. Maintaining a specific physical activity and fitness level is crucial given the pandemic situation. The connection between physical fitness and mental health has recently received growing attention. In contrast to the message from physiological research, which lauds the general benefits of fitness for physical health, the corresponding psychological literature reveals a more complex relationship. This paper outlines the research evidence, focusing on the relationship between physical fitness and depression, anxiety, and stress before and during the COVID-19 pandemic. Data were obtained from 390 higher education students (measuring their perception before and during the pandemic). They were analyzed by a structural equation modeling multi-group analysis to detect the variance in the test relationship before and during the COVID-19 pandemic. Theoretical and empirical implications are also discussed.

Effect of Forest Users' Stress on Perceived Restorativeness, Forest Recreation Motivation, and Mental Well-Being during COVID-19 Pandemic

Even though the COVID-19 pandemic has discouraged travel and people’s movements, the number of visitors to forests near cities which are easily accessible by private vehicle is increasing in Korea. This study aims to investigate the relationship between stress, perceived restorativeness, forest recreation motivation, and the mental well-being of forest users. A survey of forest users was conducted at three recreational forests near Seoul in the summer of 2020. A total of 1196 forest users (613 males and 583 females) participated in the study. As a result of the data analysis, it was found that stress had a negative correlation with perceived restorativeness, forest recreation motivation, and mental well-being; perceived restorativeness had a positive correlation with mental well-being, and forest recreation motivation had a positive correlation with mental well-being. For the relationship between stress and mental well-being, the fitness index that was mediated by the perceived restorativeness and the forest recreation motivation found that the model was statistically suitable. Through this study, a research model was derived that, if the stress of forest users is reduced, direct or indirect effects on perceived restorativeness, forest recreation motivation, and mental well-being are increased. Further, a multi-group analysis found that the effect of perceived restorativeness and forest recreation motivation on the mental well-being of the male group was higher than the effect on the female group. Using this research model to find ways to promote health in forests can be utilized for forest management or forest healing.

Factors Associated with Transphobia: A Structural Equation Modeling Approach

Our study examined factors associated with transphobia with a particular focus on the interrelations between religious fundamentalism and contact to impact transphobia. We used an online sample of U.S. adults (Mean age = 38.91 years, SD = 12.58 years; n = 400) to conduct a partially latent variable SEM analysis and tested the direct effects of religious fundamentalism, contact, and gender on transphobia and the indirect effects of religious fundamentalism on transphobia through contact. We additionally tested for gender differences in the structural relations of the variables through a multi-group analysis. Results showed a statistically significant effect of religious fundamentalism, contact, and gender on transphobia. Religious fundamentalism also had a statistically significant indirect effect on transphobia through contact. Gender differences were also found for the effects of religious fundamentalism on contact and on transphobia. We conclude with implications for research and practice.

Psychometric Properties of the SOC-13 Scale in Colombian Adults

The aim of this study was to determine the psychometric properties of the Spanish version of the SOC-13 in Colombian adults. The SOC-13 questionnaire was administered to 489 individuals aged ≥18 years who were in lockdown from March to July 2020 in Nariño County, Colombia. Psychometric properties of the scale were examined using a cross-validation method via exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). Additionally, configural and metric invariance were tested. To determine the internal consistency of the questionnaire, McDonald’s omega (ω), Cronbach’s alpha (α), and composite reliability (CR) coefficients were estimated. The EFA determined that a three-factor structure best fit the data (comprehensibility, manageability, and meaningfulness) and CFA confirmed this three-factor model structure showing a good fit (χ²_S-B = 188.530, χ²_S-B/(62) = 3.615, p = 0.001; NNFI = 0.959; CFI = 0.968; RMSEA = 0.052 (90% CI [0.041–0.063]) and SRMR = 0.052).The invariance analysis indicated the same underlying theoretical structure between genders. Additionally, (ω), (α), and (CR) coefficients confirmed a high internal consistency of the instrument. The SOC-13 scale, reflecting comprehensibility, manageability, and meaningfulness, is a reliable and valid tool for assessing the sense of coherence in Colombian populations.

Customer Loyalty in Recreational Long-Distance Races: Differences Between Novice and Experienced Runners

A growing number of recreational races are being held in different locations, drawing many local and visiting runners. This study examined the relationships between quality, value, satisfaction, and loyalty among runners in a recreational race and examines potential differences in relationships between these constructs based on the runners’ experience. The participants were 985 runners with a mean age of 40.74±9.41years. Validated, reliable ad hoc instruments were used. A multi-group analysis was performed to ascertain the existence of relationships between the constructs and differences in the relationships between the different study groups. The results show that quality is a direct antecedent of value and satisfaction. Value is directly related to satisfaction and indirectly related to loyalty. Satisfaction is related to the loyalty of participants in the race. Differences in the relationship between satisfaction and loyalty were dependent upon the runners’ experience. Loyalty to a race depends primarily on satisfaction and is modified by the runners’ experience.

The Importance of Intra-Organizational Networking for Younger Versus Older Workers: Examining a Multi-Group Mediation Model of Individual Task Performance Enhancement

The purpose of this paper is to investigate the effect of intra-organizational networking on individual task performance, via employability. Moreover, this study also examines whether this relationship differs for younger (<40 years) versus older employees (≥40 years). A self-report questionnaire was distributed among a sample of employees working in a range of different types of organizations (n = 374). We conclude that employability fully mediates the relationship between intra-organizational networking and individual task performance. However, this mediation effect did not vary between younger and older employees. This study extends past research by applying a human capital perspective (in particular, social capital) and life-span development frameworks for explaining employability and task performance enhancement across one's working life. It provides useful insights for stimulating career development and individual performance growth, by means of social capital, herewith increasing the individual employee's chance to survive in nowadays' labor markets.

Application of satisfaction index of basic medical insurance for rural and urban residents to pupils familial decision making in Kunming and Changsha City

OBJECTIVES

To verify the applicability and extensibility of the satisfaction index of basic medical insurance for rural and urban residents, and to explore the mechanism responsible for the satisfaction index in Kunming and Changsha City, and provide references for effective management and policy making.

METHODS

A stratified cluster sampling method was conducted. A total of 560 familial decision makers were randomly selected in 24 classes of 14 schools of Kunming and Changsha City. Model reliability was tested by SPSS18.0. In addition, Smart PLS 3.0 was applied to conduct model validity test, calculate the satisfaction index, and to compare the model path coefficients of Kunming and Changsha by multi-group analysis.

RESULTS

In the application of the satisfaction index of basic medical insurance for rural and urban residents in Kunming, Cronbach's α of the model was 0.93, split-half reliability coefficient was 0.90, and the latent variable composite reliability coefficient values were more than 0.86; the latent variable average variance extraction (AVE) values were greater than 0.66, and the square root of the AVE of each latent variable (all greater than 0.66) was larger than the correlation coefficient with other latent variables. The factor loading values were greater than 0.70, with statistical significance. The basic health insurance satisfaction index of Kunming and Changsha was 60.40 and 52.05, respectively. The difference between the path coefficient of Kunming and Changsha was not statistically significant except the path from public satisfaction to public loyalty. Perceived value had the largest direct and total effect on public satisfaction latent variable in Kunming City. While the perceived value had the largest direct effect on public satisfaction, and the perceived quality had the largest total effect on public satisfaction in Changsha City.

CONCLUSIONS

The satisfaction index model reflects the satisfaction of pupils' basic medical insurance for urban and rural residents, and it also shows good reliability and validity in Changsha and Kunming. What's more the model can be extended to the national level to evaluate the satisfaction of basic medical insurance for urban and rural residents for primary school students. The basic health insurance satisfaction index of familial decision makers in Kunming is higher than that of Changsha. There are differences between Kunming and Changsha in the influential mechanism of the satisfaction index of for Chinese pupils with basic medical insurance for rural and urban residents, and the measures taken by the government and relevant departments to improve the satisfaction of basic medical insurance should be based on local conditions.

Structure and Measurement Invariance of Ethnic Identity for Native American College Students

With a specific focus on the Native American population, the current study investigated the structure of ethnic identity, measured by the Multigroup Ethnic Identity Measure, using a bifactor model across Native American (n = 307), Asian (n = 348), and White (n = 549) undergraduate students. We further investigated measurement invariance across ethnic groups that shared the same factor structure. The results indicated that ethnic identity can be modeled by a bifactor structure with a general factor and two group factors, affective pride and exploration, for Native American and Asian respondents but not White respondents. In addition, measurement invariance tests supported partial weak invariance between the Native American group and the Asian group. The current findings suggest that comparisons of ethnic identity scores across ethnic groups should be treated with caution.

Drivers of participation in Facebook long-term care groups: Applying the use and gratification theory, social identification theory, and the modulating role of group diversity

Facebook long-term care groups have been established by long-term care workers, and few studies have explored the related drivers of participation from the perspective of caregivers. This study applied a mixed-methods approach; the qualitative component conducted a pilot study to explore the drivers of participation in Facebook long-term care groups and found that the use and gratification theory provides a valid approach for explaining these drivers. Subsequently, the quantitative component, based on the use and gratification theory, proposed a conceptual model to examine the effect of these drivers on the social identity of these groups as well as the modulating effects of extraversion and group diversity in terms of age and educational background. The results showed that the most important social identification-related driver underlying participation in these groups was self-discovery. In addition, the relationship among these drivers and social identification was found to be modulated by extraversion, age, and educational background.

Researching Parental Socialization Styles across Three Cultural Contexts: Scale ESPA29 Bi-Dimensional Validity in Spain, Portugal, and Brazil

Recent research that relates parenting with adolescent adjustment has shown the importance of considering the cultural context of the relationship. New results are emerging when considering the classical four-typologies model of parental socialization in some European and South-American countries. Among the instruments used in this emergent research is the Parental Socialization Scale ESPA29. This scale is a bi-dimensional parenting instrument that was specifically developed to measure the four parenting typologies, through the dimensions of acceptance/involvement and strictness/imposition. This study examines the good fit of the orthogonal bi-factor model based on the ESPA29 versus one-dimensional and bi-dimensional oblique alternative models, with three adolescent samples from 12 to 17 years old (53.4% girls), from Spain (N = 826), Portugal (N = 752), and Brazil (N = 628). We applied structural equation models (SEMs) to analyze the fit of the models to the data. The results confirm a better fit to the data for the orthogonal bi-factor model versus one-dimensional and bi-dimensional oblique alternative models across country, adolescent sex, and the three age groups. Additionally, the convergent validity of the scale was proved by showing the relation of the two parenting dimensions with self-concept. The results guarantee the adequacy of the ESPA29 to measure parenting styles.

Validation of the Five-Factor Self-Concept Questionnaire AF5 in Brazil: Testing Factor Structure and Measurement Invariance Across Language (Brazilian and Spanish), Gender, and Age

Self-concept is widely conceptualized as multidimensional (Shavelson et al., 1976). The Five-Factor Self-Concept Questionnaire (AF5, García and Musitu, 2009) assesses five specific dimensions (i.e., academic, social, emotional, family, and physical). It is a psychometrically sound questionnaire, developed, and normed in Spain, which is widely used with Spanish-speaking samples. The validation of the AF5 in Brazil would expand its potential, and would facilitate cross-cultural research. To validate the Brazilian version of the AF5, the present study apply confirmatory factor analysis and multi-sample invariance analysis across sex (women vs. men), age (11–18 years old), and language (Brazilian [Portuguese] vs. Spanish). The sample consisted of 4,534 students (54.6%, women, 53.7%, Spanish) ranging in age from 11 to 18 years old (M = 14.61, SD = 2.09). The findings of the present study confirmed that the five-dimensional AF5 factorial structure provided the better fit to the data compared to alternative one-dimensional and orthogonal five-dimensional structures. The 30 items loaded appropriately on the five dimensions. Multi-group analysis for invariance between sex, age, and language groups showed equal loading in the five factors, equal covariation between the five dimensions, and equal error variances of items. Additionally, in order to obtain an external validity index, the five AF5 factors were related to both acceptance/involvement and strictness/imposition parenting dimensions. These results provide an adequate basis for meaningful comparative studies on a highly relevant construct, multidimensional self-concept, between male and female adolescents of different ages, and Brazilian (Portuguese) and Spanish-speaking samples. These results validate the instrument and confirm its suitability in cross-cultural research.

The Behavioral Regulation in Exercise Questionnaire (BREQ-3) Portuguese-Version: Evidence of Reliability, Validity and Invariance Across Gender

This study has as prime objective to analyze the psychometric properties of the Behavioral Regulation Exercise Questionnaire (BREQ-3) in a sample of Portuguese exercisers and invariance across gender. Two independent samples (448 calibration; 374 validation), aged between 16 and 78 years (M = 40.29; SD = 16.24), of both gender, (495 female; 327 male) were enrolled in this study. The results show that the original model (six factors; 24 items) did not fit to the data in a satisfactory way (χ² = 977.49; df = 237; B-S p < 0.001; SRMR = 0.07; NNFI = 0.80; CFI = 0.83; RMSEA = 0.08; 90% CI = 0.08-0.09). After removing six items (one for each factor), the model (six factors; 18 items) adjustment improved in a satisfactory way in both samples: calibration (χ² = 331.86; df = 120; B-S p < 0.001; SRMR = 0.06; NNFI = 0.91; CFI = 0.93; RMSEA = 0.06; 90% CI 0.06-0.07) and validation (χ² = 254.08; df = 120; B-S p < 0.001; SRMR = 0.04; NNFI = 0.93; CFI = 0.95; RMSEA = 0.06; 90% CI = 0.05-0.06). Results also showed model invariance across gender (ΔCFI ≤ 0.01). The Portuguese version of BREQ-3 (six factors; 18 items) is a valid and reliable measurement instrument to measure behavior regulation underlying self-determination theory in the exercise domain. However, the evidence also indicated that additional studies are needed to address the fragilities of the original model (six factors; 24 items).

Perceived Effort in Football Athletes: The Role of Achievement Goal Theory and Self-Determination Theory

This study examined the motivational determinants of athletes perceived effort in football considering the four-stage motivational sequence at the contextual level proposed by Hierarchical Model of Intrinsic and Extrinsic Motivation: task-involving climate, basic psychological needs, self-determined motivation (SDM), and perceived effort. Additionally, SEM multi-group analysis across different age-groups (U15, U17, U19, and U21 years) and serial mediation of basic psychological needs (BPNs) and SDM on the task-involving motivational climate and the perceived effort were also analyzed. Two independent samples of male football athletes (N = 403, N = 403), aged 13–20 years were enrolled in this study. The results support the adequacy of the structural model in explaining the perceived effort of football atheltes in all samples under analysis, and was invariant across U17, U19, and U21. However, it was not invariant across U15 and U17, U19 and U21. Furthermore, results from the serial mediation showed significant indirect effects in all samples, supporting self-determination theoretical assumptions, reinforcing the importance of BPNs satisfaction and behavioral regulation in the relation in analysis. The results show that when coaches promote a task-involving climate, the BPNs satisfaction of athletes improves. This climate will facilitate the regulation of their behaviors toward more autonomous forms of motivation, with positive outcomes in the athletes perceived effort.

Older Workers and Affective Job Satisfaction: Gender Invariance in Spain

Older employees’ affective job satisfaction is an aspect that arouses growing interest among researchers. Among the affective measures of job satisfaction, the Brief Index of Affective Job Satisfaction (BIAJS) is one of the most used in the last decade. This study is intended to the test the gender invariance of the BIAJS in two samples of workers over age 40 in Spain. The first sample, of 300 participants and the second sample, of 399 participants, have been used to test gender invariance of the BIAJS. In comparison with the original English version, the Spanish version of the BIAJS has adequate psychometric properties. The findings allow us to consider it a valid and reliable tool to assess older people’s affective expressions about their work. In addition, this study provides evidence of its factorial invariance as a function of gender.

Motivational Climate Sport Youth Scale: Measurement Invariance Across Gender and Five Different Sports

The aim of this study was to analyze the psychometric properties of the Portuguese version of the Motivational Climate Sport Youth Scale (MCSYSp) and invariance across gender and different sports (swimming, soccer, handball, basketball, futsal). A total of 4,569 athletes (3,053 males, 1,516 females) from soccer (1,098), swimming (1,049), basketball (1,754), futsal (340), and handball (328) participated in this study, with ages between 10 and 20 years (M = 15.13; SD = 1.95). The results show that the original model (two factors/12 items) did not adjust to the data in a satisfactory way; therefore, it was necessary to change the model by removing four items (two from each factor). Subsequently, the model adjusted to the data in a satisfactory way (χ² = 499.84; df = 19; χ²/df = 26.30; p < .001; SRMR = .037; TLI = .923; CFI = .948; RMSEA = .074; IC90% .069–.080) and was invariant by gender and team sports (soccer, handball, basketball, futsal) (ΔCFK≤.01); however, it was not invariant between swimming and team sports (soccer, handball, basketball, futsal) (ΔCFI ≥ .01). In conclusion, the MCSYSp (two factors/eight items) is a valid and reliable choice that is transversal not only to gender, but also to the different studied team sports to measure the perception of the motivational climate in athletes. Future studies can research more deeply the invariance analysis between individual sports to better understand the invariance of the model between individual and team sports.

Gender differences in inflammatory bowel disease: Explaining body image dissatisfaction

The aim of this study was to examine the role of body image problems in the context of inflammatory bowel disease and to explore gender differences in these associations. A sample of inflammatory bowel disease patients (60 males and 140 females) was collected. Findings from a multi-group analysis show that inflammatory bowel disease symptomatology may impact on body image in both male and female patients through the effect of body-image-related cognitive fusion. Body image difficulties in the context of inflammatory bowel disease should not be a neglected dimension in research aiming at understanding the psychosocial effects of inflammatory bowel disease and by health professionals working with these patients.

Health Risk Behavior Among Justice Involved Male and Female Youth: Exploratory, Multi-Group Latent Class Analysis

BACKGROUND

Youth involved in the juvenile justice system experience a disproportionate prevalence of serious mental health issues, substance abuse, and are at an increased risk of engaging in risky sexual practices. Gender differences exist, with girls at a markedly greater risk of acquiring a sexually transmitted disease.

OBJECTIVES

The present study seeks to determine if there are subgroups of male and female youth who differ in their health risk behavior. If so, do any male or female subgroups at different levels of health risk differ in regard to their sociodemographic and psychological factors, and finally, what are intervention/service delivery implications of these differences.

METHODS

Youth were participants in an innovative health service at a centralized intake facility located in a large southeastern U.S. city. Latent class analysis and multinomial logistic regression is utilized to examine the heterogeneity of health risk behaviors across gender groups in a sample of 777 newly arrested youth.

RESULTS

Results indicate a three class solution provided the optimal fit with the data for each gender group: a Lower Health Risk group, a Higher Health Risk group, and a Highest Health Risk group. Multinomial logistic regression analysis identified significant sociodemographic and depression effects among both male and female youth. Conclusions/Importance: Youth characterized by risky sexually behavior, elevated depression, and drug involvement should be the focus of integrated intervention services. This study documents the critical need for front end, juvenile justice intake facilities to provide behavioral and public health screening, with treatment follow-up, on newly arrested youth.

Comparing Indirect Effects in Different Groups in Single-Group and Multi-Group Structural Equation Models

In this article, we evaluated the performance of statistical methods in single-group and multi-group analysis approaches for testing group difference in indirect effects and for testing simple indirect effects in each group. We also investigated whether the performance of the methods in the single-group approach was affected when the assumption of equal variance was not satisfied. The assumption was critical for the performance of the two methods in the single-group analysis: the method using a product term for testing the group difference in a single path coefficient, and the Wald test for testing the group difference in the indirect effect. Bootstrap confidence intervals in the single-group approach and all methods in the multi-group approach were not affected by the violation of the assumption. We compared the performance of the methods and provided recommendations.

Using mixture models with known class membership to address incomplete covariance structures in multiple-group growth models

Multi-group latent growth modelling in the structural equation modelling framework has been widely utilized for examining differences in growth trajectories across multiple manifest groups. Despite its usefulness, the traditional maximum likelihood estimation for multi-group latent growth modelling is not feasible when one of the groups has no response at any given data collection point, or when all participants within a group have the same response at one of the time points. In other words, multi-group latent growth modelling requires a complete covariance structure for each observed group. The primary purpose of the present study is to show how to circumvent these data problems by developing a simple but creative approach using an existing estimation procedure for growth mixture modelling. A Monte Carlo simulation study was carried out to see whether the modified estimation approach provided tangible results and to see how these results were comparable to the standard multi-group results. The proposed approach produced results that were valid and reliable under the mentioned problematic data conditions. We also present a real data example and demonstrate that the proposed estimation approach can be used for the chi-square difference test to check various types of measurement invariance as conducted in a standard multi-group analysis.
