The relationships of Internet use, web communication, and sources of social support with adolescent self‐injurious thoughts and behaviors (SITBs) in Taiwan were investigated. The study sample of 391 12 to 18‐year‐olds was selected from nine public high schools. Findings show that girls are more likely to have SITBs, except for suicide gestures. Web communication is a risk factor for SITBs in boys but not in girls. Family support is protective in both genders. Support from friends is protective and support from significant others was a risk factor for suicide plans in girls. Support from virtual social communities can have both positive and negative effects on adolescent SITBs, with different effects by gender. 相似文献
Documented risk factors for suicide among alcohol‐dependent patients are sensitive but insufficiently specific to effectively identify individuals who are prone to future suicide attempt. As a first step to assess factors not previously considered, this pilot study involved a group of male alcohol‐dependent patients (N = 175) coming to detoxification to examine the potential utility of adverse childhood experiences (ACE) along with other documented events to discriminate individuals with a history of attempted suicide from their detoxifying peers. Family health history questionnaires were used to evaluate their ACEs. Receiver operating characteristic (ROC) analysis was applied to examine the predictive power of ACEs, alone or in combination with documented risk factors, to lifetime history of attempted suicide. Among our participants, 48 (27.4%) had a history of a suicide attempt and 156 (89.1%) reported at least one out of the nine categories of ACEs. Modeling by ROC analysis, we found that a cutoff of four or more ACEs plus a history of personal violence achieved the best predictive power to a history of any suicide attempt, producing a sensitivity of 0.7, specificity of 0.81, and area under curve of 0.75. A prospective study to replicate and extend our findings is necessary. 相似文献
This study is the first to evaluate evidence for measurement invariance and the psychometric properties of the Suicide Resilience Inventory‐25 (SRI‐25; Osman et al., 2004 ) in college‐age samples in both the United States and China. We found strong support for full measurement invariance of the three‐factor structure of the SRI‐25 in the U.S. (113 men and 238 women) and Chinese (121 men and 205 women) samples. In addition, we found that the U.S. sample scored significantly higher than the Chinese sample on all the individual scale scores. Composite scale reliability estimates ranged from moderate (ρ = .83) to high (ρ = .93) across the groups. Although not an aim of the current study, we examined estimates of internal consistency of the SRI‐25 scales for men and women within each sample. Differential correlates of the SRI‐25 scales were explored further for each sample. These results provide support for the use of the SRI‐25 in U.S. and Chinese student samples. 相似文献
Observational data typically contain measurement errors. Covariance-based structural equation modelling (CB-SEM) is capable of modelling measurement errors and yields consistent parameter estimates. In contrast, methods of regression analysis using weighted composites as well as a partial least squares approach to SEM facilitate the prediction and diagnosis of individuals/participants. But regression analysis with weighted composites has been known to yield attenuated regression coefficients when predictors contain errors. Contrary to the common belief that CB-SEM is the preferred method for the analysis of observational data, this article shows that regression analysis via weighted composites yields parameter estimates with much smaller standard errors, and thus corresponds to greater values of the signal-to-noise ratio (SNR). In particular, the SNR for the regression coefficient via the least squares (LS) method with equally weighted composites is mathematically greater than that by CB-SEM if the items for each factor are parallel, even when the SEM model is correctly specified and estimated by an efficient method. Analytical, numerical and empirical results also show that LS regression using weighted composites performs as well as or better than the normal maximum likelihood method for CB-SEM under many conditions even when the population distribution is multivariate normal. Results also show that the LS regression coefficients become more efficient when considering the sampling errors in the weights of composites than those that are conditional on weights. 相似文献
Background: Few studies have examined the complex relationship of migration stress and depression with sexual risk behaviors among migrants. The relationship between migration stress and sexual risk behaviors may be mediated by depression, and the mediation process may be modified by social capital. The study aims to investigate this moderated mediation mechanism among rural-to-urban migrants.
Methods: Data were collected from rural-to-urban migrants in China. Migration stress, depression, and social capital were measured with validated scales and used as predictor, mediator and moderator, respectively, to predict the likelihood of having sex with risk partners. Mediation and moderated mediation models were used to analyze the data.
Results: Depression significantly mediated the migration stress–sex with risk partner relationship for males (the indirect effect [95%CI]?=?0.36 [0.08, 0.66]); the mediation effect was not significant for females (0.31 [?0.82, 0.16]). Among males, social capital significantly moderated the depression-sex with risk partner relation with moderation effect ?0.12 [?0.21, ?0.04], ?0.21 [?0.41, ?0.01] and ?0.17 [?0.30, ?0.05] for total, bonding and bridging capital respectively.
Conclusion: Social capital may weaken the association between migration stress and sexual risk behavior by buffering the depression-sexual risk behaviors association for males. Additional research is needed to examine this issue among females. 相似文献
