+<br>The study was part of the NIMH Collaborative Epidemiology Survey (CPES) initiative that included three national representative surveys - the NSAL, the National Comorbidity Survey Replication (NCS-R), and the National Latino and  [Vitalix Prime Review](https://wikibuilding.org/index.php?title=Exploring_The_Benefits_Of_Buying_Vitalix_Prime) Asian American Study (NLAAS). The NSAL data collection was based on a multi-stage area probability sample using a stratified and clustered sample design, resulting in the creation of the variables stratum and cluster. The first stage of selection used a stratification approach of selecting 64 Primary Sample Units (PSUs) for the Core sample and an additional 8 PSUs for the Caribbean Supplement. The second stage of selection used a clustering approach of selecting area segments within each PSU. Clustering was used to reduce the cost of data collection since groups (clusters) of frame elements, rather than individual frame elements, were selected for inclusion in a study. Data were collected using a stratified and clustered sample design. The NSAL sample included 66 strata, most of which contain two clusters. One Caribbean stratum, however, included eight clusters.<br>

+<br>Thus, the total number of clusters for the NSAL is 138. Greater detail on how the NSAL strata and clusters were created from the PSUs and segments can be found in the following publications including the NSAL technical report on sample design, weighting and variance estimation: 1.

Interviews were conducted with 1170 African American and [Caribbean](https://www.gov.uk/search/all?keywords=Caribbean) Black adolescents 13-17 years of age who were attached to the NSAL adult households. There were no adolescent White respondents. Some survey items were asked of only males or females: Adolescent males only were administered SS46-SS51 (non-residential father issues) and HE21-HE23 (male pubertal development), while adolescent females only were administered SS39-SS45 (non-residential father issues) and PR1-PR50 (women's health section). Similarly to the NSAL adult dataset, the adolescent dataset contains detailed measures of health; mental disorders; social conditions; stressors; distress; racial identity; subjective, neighborhood conditions; activities and school; media; and social and psychological protective and risk factors. The final overall response rate for the adolescent sample was 80.6 percent, with response rates of 80.4 percent and 83.5 percent for African American and Caribbean Black adolescents, respectively. Level of impairment associated with many of the individual disorders was assessed by the Sheehan Disability Scale. This scale assesses disability in the domains of home, work, relationships, and social life, and was assessed for depression, mania, irritable major depression, panic, social phobia, agoraphobia, generalized anxiety disorder, intermittent explosive disorder, post-traumatic stress disorder, eating disorders, and oppositional defiant disorder.<br>

+<br>As some of you may know, I started out as a radio journalist. And when I discovered the web in around 1996, I knew that, to me, radio and TV were not the dominant news media any longer. Nowhere but on the web was it possible to research and cross-reference from dozens or resources with various origins. You could directly access the press agencies for news without having to read the politically or sensationalist tainted derivates in various outlets. The amazing thing was the humble link. And  [Vitalix Prime men's performance](http://ingeekswetrust.de/index.php?title=Benutzer:GilbertoBungaree) as the cool kids said back then Cool URIs don’t change. In other words, the web was about retention and accumulation of content. An ever growing library that by its very nature was self-indexing and cross-referencing. And this is what is being actively killed these days. But let’s go back a bit before I start focusing on that problem. Let’s take a peek at the slow decline of the web as a news medium.<br>
+
+<br>The great thing about the web was that everyone could become a publisher and let their voice be heard. Finding places to write and create web pages was easy. But many of them were also short-lived and we learned the hard way when - for example - Geocities shut down, "free" didn’t mean "yours forever online". When "web2.0" became a thing, the publishing model got turned on its head. Instead of writing in an own publication, the idea was to comment and do smaller posts on a topic, linking to resources, or adding a funny image without alternative text. Accumulatively adding to threads, so to say. A bit of a reminder of Bulletin Boards or Forums, but with less focus. At that time I worked on various social media ideas in Yahoo, hitherto one of the main sources for people’s daily news, replacing daily papers. The model of Yahoo and others back then was simple: buy news content, spruce it up a bit and show ads around it.<br>
+
+<br>Even then some dark patterns evolved, like splitting up longer content into carousels and pagination not for the sake of the user, but to record yet another click. Clicks and interaction means ad displays, reading was kind of a necessary evil from a monetisation point of view. This is also when the first ideas of creating sticky, viral and - let’s call it by its real name - addictive and lock-in content came up. Something we perfected now, but still wanted to avoid back then. Back then "web 2.0" or user generated content was something we didn’t quite trust and the biggest no-no was to create a product for a community for the sake of having one. This anti-pattern was called the Potemkin Villages, when historically people build fake villages for the emperor  [vitalixprimes.com](https://wikibuilding.org/index.php?title=User:ConstanceUnh) to see when driving past so he’d see growth where there wasn’t any. So, instead of growing a community, you build an empty product.<br>
