Previous suicide attempts are a leading risk factor for completed suicide. To identify specific characteristics of those at high risk for attempts, we investigated associations with socioeconomic status (SES). Data from the 2013 Korean Community Health Survey (KCHS) included adults who reported suicidal ideation (N = 220,245). Attempts in the past 12 months were assessed. Associations of demographic, socioeconomic, and suicide‐related behavioral factors were analyzed using multiple logistic regression. Among those with suicidal ideation, 862 (3.9%) had attempted suicide. After stratification by age and gender, results showed that low education and unemployed young adult men and women had significantly higher rates of attempts. The lowest income level was associated with significantly higher rates of attempts in only young adult women. Among those with the lowest and highest income, the association between ideation and attempts was attenuated, whereas it was enhanced among other income groups. 相似文献

AbstractThis study examines the psychometric properties of a reading motivation measure with a sample of upper elementary students in the United States (n?=?195). The research explores upper elementary students’ motivation to read, the amount/frequency of their reading in general, and their preferences for different text genres. Factor analyses support the validity and reliability of the SRQ-RM for upper elementary students in the United States, a tool not previously used with this population. This study also included a nuanced assessment of students’ genre preferences, which has implications for reading motivation and effective classroom instruction. 相似文献

A lack of human interaction and environmental control in Internet-based data collection have been suggested as possible antecedents of careless responding, which occurs when participants respond to survey items without regard for item content. To address these possible antecedents, this study investigated whether survey proctoring deterred careless response in an undergraduate sample by reducing environmental distractions. The study randomly assigned respondents to one of three proctoring conditions: remote online un-proctored, remote online virtually proctored, and in-person classroom proctored. Data quality was examined via nine careless response indicators. Analyses indicated that proctor presence had effects on a small number of careless response indicators. Virtually proctored participants performed better than un-proctored participants on one of nine careless response indicators, and in-person proctored participants performed better on two careless response indicators compared to un-proctored participants. Environmental distraction fully mediated the relationship between in-person proctor presence and self-reported diligence. Implications for survey administration are discussed. 相似文献

We perceive smells as perduring complex entities within a distal array. However, odor theories have been recently criticized for their conception of the spatiotemporal nature of olfactory perception and the individuation of distal odors. The paper does not aim to dispute these criticisms. Rather, what will be shown is that molecular structure theory, a refinement of odor theory, can be further developed to handle these challenges. The theory is further refined by focusing on distal perception that requires considering the perceptual object as mereologically complex persisting odor against a background scene conceived of as a smellscape. 相似文献
