The associations between problematic Internet use (PIU) and depressive symptoms have been found to be positive and statistically significant. However, whether the trajectory change of depressive feeling is related to PIU has not been discovered. The present study aimed to investigate the trajectory change of depressive symptoms in a group of Taiwanese college students and to examine the influence of the initial level and the changing rate in depression on the PIU level, with a simultaneous evaluation of gender effect. The survey employed a five-wave panel design in which the data were collected five times from the freshman to junior years for the same participants. The first-year data included 757 freshmen (51.1% male). The results showed that the females exhibit a faster decreasing rate in depression than the males. A student with a higher initial level of depression tends to have a serious initial level of PIU. Additionally, the PIU level at the end of study period could be reduced while the rapidly decreasing rate of depression was observed. The faster the decline in depression is, the lower the PIU level is. The trajectory change of depression plays an important role in predicting the severity of PIU. (C) 2015 Elsevier Ltd.

Background. Marsh's internal/external (I/E) frame of reference model depicts the relationship between achievement and self-concept in specific academic domains. Few efforts have been made to examine concurrent relationships among cognitive ability, achievement, and academic self-concept (ASC) within an I/E model framework. Aim. To simultaneously examine the influences of domain-specific cognitive ability and grades on domain self-concept in an extended I/E model, including the indirect effect of domain-specific cognitive ability on domain self-concept via grades. Sample. Tenth grade respondents (628 male, 452 female) to a national adolescent survey conducted in Taiwan. Method. Respondents completed surveys designed to measure maths and verbal aptitudes. Data on Maths and Chinese class grades and self-concepts were also collected. Results. Statistically significant and positive path coefficients were found between cognitive ability and self-concept in the same domain (direct effect) and between these two constructs via grades (indirect effect). The cross-domain effects of either ability or grades on ASC were negatively significant. Conclusions. Taiwanese 10th graders tend to evaluate their ASCs based on a mix of ability and achievement, with achievement as a mediator exceeding ability as a predictor. In addition, the cross-domain effects suggest that Taiwanese students are likely to view Maths and verbal abilities and achievements as distinctly different.

Cross-lagged analysis of panel survey data collected from Taiwanese college students (initially 387 males and 370 females) was used to examine the temporal relationship between problematic Internet use (PIU) and lifestyle changes during the first year in college. We hypothesized that a reciprocal relationship might exist between PIU and lifestyle changes. Structural equation modeling was adopted to test several nested cross-lagged relationship models. The results showed that four measures of lifestyle changes and PIU were moderately to highly stable across one year. Moreover, PIU in freshman year predicted negative changes in lifestyle in the following year, including a reduction of physical and social activities, irregular diet and unhealthy sleep. Lifestyle changes in freshman year, in contrast, did not predict PIU in sopho-more year; the hypothesized reciprocal relationship between PIU and lifestyle changes was not warranted. Implications and limitations are discussed. (C) 2013 Elsevier Ltd. All rights reserved.

By using the 2 x 2 achievement goal framework, this study assessed the math achievement goal profiles of 488 Taiwanese students from Grades 7 to 8. In the first year, three math achievement goal profiles were identified using latent profile analysis: maladaptive, indifferent, and success-oriented. A slightly different profile, avoidant-but-adapting, was found in the second year in addition to the indifferent and success-oriented profiles. Success oriented students showed the most adaptive pattern of motivation, with high approach orientations, while maladaptive students demonstrated less-adaptive learning characteristics, with high avoidance orientations. Avoidant-but-adapting students exhibited high scores for avoidance and mastery-approach orientations. The goal profiles were investigated with respect to stability and change over one year transition. Our study reflects mastery-avoidance goal's unique contribution to the classification of students and its' influences on educational and psychological outcomes and provides insights into the 2 x 2 model of achievement goal orientations.

Previous research has suggested that problematic Internet use (PIU) is associated with impulse control disorder. Although researchers have suggested that impulsivity is a risk factor for PIU, the literature lacks longitudinal evidence on the relationship between impulsivity and PIU. We aimed to use a cross-lagged analytic framework to identify temporal order effects and hypothesised that impulsivity was the precedent factor for PIU. In a panel sample of college students (N = 367), trait impulsivity and PIU were measured in the spring of freshman year and in their junior year. The measures included a self-developed PIU Scale and the revised Impulsiveness Scale based on Barratt's concept. We found that "non-planning impulsivity" was not associated with PIU. The "motor impulsivity" subfactor was thus adopted in the cross-lagged model. The results suggest that motor impulsivity and PIU were stable across time. Motor impulsivity at Time 1 positively predicted PIU at Time 2, but PIU at Time 1 did not predict motor impulsivity at Time 2. A further investigation using gender as a moderator found a gender difference in the temporal relationship. Because motor impulsivity is a risk factor for PIU, potential prevention strategies based on this result are suggested.

Studies of correlations between Internet use and psychological well-being (PW) have produced mixed results. The present study used a latent profile analysis to distinguish among populations in terms of PW profiles, and then used a multinomial logistic regression to determine how online entertainment, social use, problematic Internet use (PIU), and gender predicted each latent PW profile. The initial sample consisted of 757 Taiwanese college freshmen. Four ordered latent groups were established as follows: good PW, normative, minor-disadvantageous, and severe-disadvantageous. No latent PW profile stability was found in subsequent years: three groups (normative, minor-disadvantageous and severe-disadvantageous) emerged in Year 2, and only one group emerged in Year 3. The results indicate (a) no relationship between PW and online entertainment or gender, (b) greater PIU increased the likelihood of disadvantageous PW and decreased the probability of good PW, and (c) greater use of online resources for social purposes was related to increased probability of a participant being in the good PW group, but not associated with fewer PW problems.

As noted in previously published literature, college students frequently experience academic stress, financial stress, and the stresses caused by intimate, peer, and parent-adolescent relationships. The present study uses latent profile analysis to identify stress profiles based on the aforementioned five stressors among 430 college freshmen. Thereafter, we compare the levels of depression and problematic Internet use (PIU) among the different profile groups and investigate whether background variables could predict each latent stress group. Three latent groups were labelled as follows: Ordinary (n = 257, 59.77%); all moderate-high (n = 98, 22.79%); and college-life moderate-high (n = 75, 17.44%). Compared with the ordinary group, the all moderate-high and college-life moderate-high groups displayed significantly higher levels of depression. Moreover, the all moderate-high group had a severer level of PIU than the college-life moderate-high and ordinary groups. Interestingly, males and students who were dating were more likely to fall under the all moderate-high group than the college-life moderate-high group; but students who were more concerned with their academic performance were more likely to fall under the college-life moderate-high group than the all moderate-high group. These findings have important implications for college educators and school counsellors with regard to developing appropriate interventions as required.

A scale measuring quality of life (QOL) is important in adolescent research. Using the graded response model (GRM), this study evaluates the psychometric properties of the satisfaction ratings of the Quality of Life Profile Adolescent Version (QOLPAV). Data for 1,392 adolescents were used to check IRT assumptions such as unidimensionality and local item dependence (LID). The goodness of fit of the GRM to the data and the item characteristic curves were evaluated. The reliability and validity analyses included item/test information, Cronbach's alpha, and convergent and discriminant validity. Differential item functioning (DIF) procedures were also performed to detect item bias. The results provide evidence that the items sufficiently measured one single dimension. Few pairs of questions were flagged as LID due to content or wording similarity. Five items did not fit the GRM, and 4 were low in item discrimination. The findings also suggest that the assessment had appropriate reliability and validity. The DIF impact on the assessment score was considered minor. Because QOLPAV includes a respondent's perceived importance of various life aspects, a short form that only considers important life aspects in the overall QOL estimation for each respondent becomes feasible within the framework of IRT. Future studies focusing on the development of a QOL overall index using the items from QOLPAV are recommended.

A real-data simulation of computerized adaptive testing (CAT) is an important step in real-life CAT applications. Such a simulation allows CAT developers to evaluate important features of the CAT system, such as item selection and stopping rules, before live testing. SIMPOLYCAT, an SAS macro program, was created by the authors to conduct real-data CAT simulations based on polytomous item response theory (IRT) models. In SIMPOLYCAT, item responses can be input from an external file or generated internally on the basis of item parameters. provided by users. The program allows users to choose among methods of setting initial theta, approaches to item selection trait estimators, CAT stopping criteria, polytomous IRT models, and other CAT parameters. In addition, CAT simulation results can be saved easily and used for further study. The purpose of this article is to introduce SIMPOLYCAT, briefly describe the program algorithm and parameters, and provide examples of CAT simulations, using generated and real data. Visual comparisons of the results obtained from the CAT simulations are presented.

The present study aimed to use a latent profile analysis to distinguish between populations in terms of life domain importance and satisfaction profiles. Then, a multinomial logistic regression was used to determine how background variables (e.g., gender, living areas, and school levels) and self-perceived health predict each latent quality of life (QoL) profile. We also investigated how the latent groups of adolescents predicted negative and positive well-being indicators (e.g., problem behaviors and overall life satisfaction). The sample consisted of 720 Taiwanese secondary school students. Three latent groups were established as follows: "unimportant-unsatisfied," "important-unsatisfied," and "important-satisfied." The results indicate the following: (a) boys were more likely to fall into the "unimportant-unsatisfied" group than were girls; (b) better health increased the likelihood of being in the "important-satisfied" group; (c) high school students were more likely to be in the "unimportant-unsatisfed" group than were middle school students; and (d) no relationship was found between latent groups and living areas. The function of importance rating was not present when evaluating the importance-satisfaction profiles and their relationship with problem behaviors and overall life satisfaction. The problems of the "unimportant-unsatisfied" profile among youth are discussed.

Marsh and Koller (2004) combined the reciprocal-effects model and the internal/external frame-of-reference model into a unified model of relationships between academic self-concept and achievement. However, this model has only been examined with German adolescents. We decided to test this model with two-wave data drawn from a national survey of Taiwanese students. We found that reciprocal effects exist for both math and Chinese for the high-school students. However, the causal relationship of academic self-concepts and achievement for pre-adolescents seems to vary depending on school subject. Moreover, the causal effects from academic achievement decline with age, whereas those from academic self-concepts increase with age, suggesting a developmental trend. The negative cross-domain effect from prior achievement to subsequent academic self-concept is not strong in the unified model. (c) 2012 Elsevier Inc. All rights reserved.
