Background Web-based self-report surveying has increased in popularity, as it can rapidly yield large samples at a low cost. Despite this increase in popularity, in the area of youth mental health, there is a distinct lack of research comparing the results of Web-based self-report surveys with the more traditional and widely accepted computer-assisted telephone interviewing (CATI). Objective The Second Australian Young and Well National Survey 2014 sought to compare differences in respondent response patterns using matched items on CATI versus a Web-based self-report survey. The aim of this study was to examine whether responses varied as a result of item sensitivity, that is, the item’s susceptibility to exaggeration on underreporting and to assess whether certain subgroups demonstrated this effect to a greater extent. Methods A subsample of young people aged 16 to 25 years (N=101), recruited through the Second Australian Young and Well National Survey 2014, completed the identical items on two occasions: via CATI and via Web-based self-report survey. Respondents also rated perceived item sensitivity. Results When comparing CATI with the Web-based self-report survey, a Wilcoxon signed-rank analysis showed that respondents answered 14 of the 42 matched items in a significantly different way. Significant variation in responses (CATI vs Web-based) was more frequent if the item was also rated by the respondents as highly sensitive in nature. Specifically, 63% (5/8) of the high sensitivity items, 43% (3/7) of the neutral sensitivity items, and 0% (0/4) of the low sensitivity items were answered in a significantly different manner by respondents when comparing their matched CATI and Web-based question responses. The items that were perceived as highly sensitive by respondents and demonstrated response variability included the following: sexting activities, body image concerns, experience of diagnosis, and suicidal ideation. For high sensitivity items, a regression analysis showed respondents who were male (beta=−.19, P=.048) or who were not in employment, education, or training (NEET; beta=−.32, P=.001) were significantly more likely to provide different responses on matched items when responding in the CATI as compared with the Web-based self-report survey. The Web-based self-report survey, however, demonstrated some evidence of avidity and attrition bias. Conclusions Compared with CATI, Web-based self-report surveys are highly cost-effective and had higher rates of self-disclosure on sensitive items, particularly for respondents who identify as male and NEET. A drawback to Web-based surveying methodologies, however, includes the limited control over avidity bias and the greater incidence of attrition bias. These findings have important implications for further development of survey methods in the area of health and well-being, especially when considering research topics (in this case diagnosis, suicidal ideation, sexting, and body image) and groups that are being recruited (young people, males, and NEET).

ObjectiveTo comparatively analyze Google, Twitter, and Wikipedia byevaluating how well change points detected in each web-based sourcecorrespond to change points detected in CDC ILI data.IntroductionTraditional influenza surveillance relies on reports of influenza-like illness (ILI) by healthcare providers, capturing individualswho seek medical care and missing those who may search, post,and tweet about their illnesses instead. Existing research has shownsome promise of using data from Google, Twitter, and Wikipediafor influenza surveillance, but with conflicting findings, studies haveonly evaluated these web-based sources individually or dually withoutcomparing all three of them1-5. A comparative analysis of all threeweb-based sources is needed to know which of the web-based sourcesperforms best in order to be considered to complement traditionalmethods.MethodsWe collected publicly available, de-identified data from the CDCILINet system, Google Flu Trends, HealthTweets.org, and Wikipediafor the 2012-2015 influenza seasons. Bayesian change point analysiswas the method used to detect change points, or seasonal changes,in each of the web-data sources for comparison to change pointsin CDC ILI data. All analyses was conducted using the R package‘bcp’ v4.0.0 in RStudio v0.99.484. Sensitivity and positive predictivevalues (PPV) were then calculated.ResultsDuring the 2012-2015 influenza seasons, a high sensitivity of 92%was found for Google, while the PPV for Google was 85%. A lowsensitivity of 50% was found for Twitter; a low PPV of 43% wasfound for Twitter also. Wikipedia had the lowest sensitivity of 33%and lowest PPV of 40%.ConclusionsGoogle had the best combination of sensitivity and PPV indetecting change points that corresponded with change points found inCDC data. Overall, change points in Google, Twitter, and Wikipediadata occasionally aligned well with change points captured in CDCILI data, yet these sources did not detect all changes in CDC data,which could indicate limitations of the web-based data or signify thatthe Bayesian method is not adequately sensitive. These three web-based sources need to be further studied and compared using otherstatistical methods before being incorporated as surveillance data tocomplement traditional systems.Figure 1.

Background: Common mental disorders have been found to be related to suicidal ideation and behavior. Research in the field of web-based interventions for common mental disorders, however, usually excludes participants with a suicidal risk, although a large proportion of participants might suffer from suicidal ideation. Aims: To investigate the prevalence of suicidal ideation in common mental disorders in an online sample. Method: In total, 502 participants completed nine web-based questionnaires on common mental disorders, of which 120 were also interviewed by telephone to obtain a diagnosis. Logistic regression analyses were applied to investigate associations between disorders and suicidal ideation. Results: Based on web-based self-report, 53% of participants had some form of suicidal ideation. Fewer participants reported suicidal ideation during the interview by telephone. Depression (multivariate odds ratio 7.1), generalized anxiety disorder (2.1), social phobia (2.1), and posttraumatic stress disorder (1.7) were significantly associated with suicidal ideation, while a higher number of comorbid common mental disorders increased the risk. Conclusion: Researchers and clinicians should be aware that one out of every two helpseekers on the internet with common mental disorders may have suicidal ideation. Comorbidity of two or more disorders greatly increase the risk of suicidal ideation.

Abstract Background The burden of disease attributable to alcohol and other drug (AOD) use in young people is considerable. Prevention can be effective, yet few programs have demonstrated replicable effects. This study aimed to replicate research behind Climate Schools: Alcohol and Cannabis course among a large cohort of adolescents. Methods Seventy-one secondary schools across three States participated in a cluster-randomised controlled trial. Year 8 students received either the web-based Climate Schools: Alcohol and Cannabis course (Climate, n = 3236), or health education as usual (Control, n = 3150). Outcomes were measured via self-report and reported here for baseline, 6- and 12-months for alcohol and cannabis knowledge, alcohol, cannabis use and alcohol-related harms. Results Compared to Controls, students in the Climate group showed greater increases in alcohol- [standardised mean difference (SMD) 0.51, p < 0.001] and cannabis-related knowledge (SMD 0.49, p < 0.001), less increases in the odds of drinking a full standard drink[(odds ratio (OR) 0.62, p = 0.014], and heavy episodic drinking (OR 0.49, p = 0.022). There was no evidence for differences in change over time in the odds of cannabis use (OR 0.57, p = 0.22) or alcohol harms (OR 0.73, p = 0.17). Conclusions The current study provides support for the effectiveness of the web-based Climate Schools: Alcohol and Cannabis course in increasing knowledge and reducing the uptake of alcohol. It represents one of the first trials of a web-based AOD prevention program to replicate alcohol effects in a large and diverse sample of students. Future research and/or adaptation of the program may be warranted with respect to prevention of cannabis use and alcohol harms.

Purpose:Suicide is the leading cause of death among Korean adolescents. This study investigates the cross-sectional relations of physical activity with suicidal ideation and attempts in adolescents, simultaneously considering previously reported risk factors of suicide such as depression, stress, and body image.Methods:This study used the 2007 Korea Youth Risk Behavior Web-based Survey (KYRBWS). Four hundred middle schools and 400 high schools in Korea were monitored, and 74,698 students completed the questionnaire. Logistic regression analysis was conducted to investigate the relationship between physical activity and suicidal ideation and attempts, progressively adjusting for body image, depression and stress.Results:After controlling for body image, stress, and depression, the significant relationship between physical activity and suicidal ideation disappeared, and the only remaining relationship was a positive relationship between frequent vigorous physical activity and suicide attempts. No sex differences were found after adjusting for all the variables.Conclusion:Unlike the general expectation that physical activity protects adolescents from suicidal behaviors, the results from this study suggest that physical activity does not have protective effect. Korean adolescents who perform frequent vigorous physical activities are more likely to attempt suicide.

Abstract. This is the first study investigating the use of a web-based version of the Youth Self-Report (YSR) compared to paper-pencil (PP) assessment. Students aged 10–18 years were recruited from Austrian schools and either completed a PP ( N = 841) or a web-based ( N = 2,769) version. Psychometric properties and indicators of data quality were analyzed. Moreover, cost estimations for the web-based and PP assessments were given. Acceptable model fits (RMSEA < .05) of the 8-syndrome model were observed for both versions and measurement invariance testing revealed strong invariance between both formats. While there was no significant difference in the number of missing items, a slightly higher proportion of web-based datasets were analyzable (97.7% vs. 93.7%). A larger amount of information was provided in the open-ended questions in the web-based version ( p < .001). Mean problem scores were equivalent, with the exception of the thought problems syndrome scale in which a slightly higher score was observed in the web-based version ( p < .001). In our study, the web-based format reduced costs by 72% compared to the PP format. Our findings suggest that large web-based epidemiological surveys are cost-efficient, can be applied without the risk of disadvantages compared to PP assessments and might be superior regarding some aspects of data quality.

High Sensitivity Detection

Labelling of antibodies with small gold probes is a highly sensitive technique for detecting specific molecules in biological tissue. Larger gold probes are usually well visible in TEM or STEM Bright-Field images of unstained specimens. In stained specimens, however, the contrast of the stain is frequently the same as that of the gold labels, making it virtually impossible to identify the labels, especially when smaller gold labels are used to increase the sensitivity of the immunolabelling technique. TEM or STEM Dark-Field images fare no better (Figs. 1a and 2a), again because of the absence of a clear contrast difference between gold labels and stain.Potentially much more useful is backscattered-electron imaging, since this will show differences in average atomic number which are sufficiently large between the metallic gold and the stains normally used. However, for the thin specimens and at high accelerating voltages of the STEM, the yield of backscattered electrons is very small, resulting in a very weak signal. Consequently, the backscattered-electron signal is often too noisy for detecting small labels, even for large spot sizes.

Abstract. Background: People who feel they have become a burden on others may become susceptible to suicidal ideation. When people no longer feel capable or productive, they may assume that friends and family members would be better off without them. Aim: The present study was designed to assess preliminary psychometric properties of a new measure, the Perceived Burdensomeness (PBS) Scale. Method: Depressed psychiatric patients (N = 173) were recruited from a veterans affairs medical center. Patients were assessed with a structured diagnostic interview and self-report measures assessing perceived burdensomeness, depression severity, hopelessness, and suicidal ideation. Results: The present study supported preliminary evidence of reliability and concurrent validity of the PBS. Additionally, perceived burdensomeness was significantly associated with higher levels of hopelessness and suicidal ideation. Conclusion: It is hoped that with the aid of the PBS clinicians may be able to intervene more specifically in the treatment of suicidality.

Background: Identifying risk factors for suicide-related thoughts and behaviors (SRTB) is essential among adolescents in whom SRTB remain a leading cause of death. Although many risk factors have already been identified, influential theories now suggest that the domain of interpersonal relationships may play a critical role in the emergence of SRTB. Because attachment has long been seen as the foundation of interpersonal functioning, we suggest that attachment insecurity warrants attention as a risk factor for SRTB. Aims: This study sought to explore relations between attachment organization and suicidal ideation, suicide attempts, and self-harm in an inpatient adolescent sample, controlling for demographic and psychopathological covariates. Method: We recruited 194 adolescents from an inpatient unit and assigned them to one of four attachment groups (secure, preoccupied, dismissing, or disorganized attachment). Interview and self-report measures were used to create four variables reflecting the presence or absence of suicidal ideation in the last year, single lifetime suicide attempt, multiple lifetime suicide attempts, and lifetime self-harm. Results: Chi-square and regression analyses did not reveal significant relations between attachment organization and SRTB, although findings did confirm previously established relations between psychopathology and SRTB, such that internalizing disorder was associated with increased self-harm, suicide ideation, and suicide attempt and externalizing disorder was associated with increased self-harm. Conclusion: The severity of this sample and methodological differences from previous studies may explain the nonsignificant findings. Nonsignificant findings may indicate that the relation between attachment organization and SRTB is moderated by other factors that should be explored in future research.

The main objective of this study was to investigate the relationship between social perfectionism, overgeneral autobiographical memory recall, and psychological distress (hopelessness, depression/anxiety, and suicidal ideation) in a sample of parasuicide patients. Forty patients who had been admitted to a Scottish hospital following an episode of deliberate self-harm participated in the study. The participants completed the autobiographical memory task and a battery of self-report measures (multidimensional perfectionism, hopelessness, depression/anxiety, and suicidal ideation). The results showed that repetitive self-harmers were more overgeneral in their recall of positive autobiographical memories than were first-time self-harmers. Hierarchical regression analyses showed that socially prescribed perfectionism interacted with overgeneral recall of both positive and negative memories to predict suicidal ideation/depression. The findings are discussed in relation to previous research.

Abstract. Background and Aim: This study evaluated trauma-related shame as a mediator of the association between sexual assault severity and perceived burdensomeness and thwarted belongingness. Method: A total of 164 female undergraduates who reported attempted or completed sexual assault completed self-report measures of sexual assault, trauma-related shame, perceived burdensomeness, and thwarted belongingness. Results: Using path analysis, trauma-related shame mediated the association between sexual assault severity and perceived burdensomeness, and between sexual assault severity and thwarted belongingness. Limitations: The findings of this study are limited by the retrospective, self-report, and cross-sectional nature of these data, and do not allow for causal inference. Conclusion: Trauma-related shame warrants additional investigation as a mechanism that explains the association between sexual assault and psychosocial risk factors for suicidal ideation and behavior.
