Removed data provided frequency and you may shot proportions, in addition to prospective moderators, including the following the: (1) age, tested constantly because a suggest; (2) gender, tested given that part of guys on the attempt; (3) first 12 months of information collection; (4) type of sexting (mobile device versus computers); and (5) message blogs (photo simply, images/videos, otherwise pictures/videos/direct chatting). Concurrently, i extracted (6) research area (You, Europe, and other) and you will (7) guide position (published during the peer-assessed log compared to dissertation otherwise report). To avoid oversampling impact size rates out-of personal studies, precisely the total study’s sexting prevalences regarding delivering, receiving, and/or forwarding sexts was illustrated (rather than sexting data stratified because of the many years, intercourse, otherwise country). On the nonconsensual forwarding off sext, study have been removed in line with the total try out-of childhood when you look at the the research (unlike sexting youth only). Whenever research out-of one or more trend of information collection was indeed given or when studies in one take to have been shown around the numerous books, i chosen the brand new revolution or publication into largest decide to try proportions additionally the really total studies extraction suggestions. To make sure precision and you can accuracy, the education was basically twice coded, and you will inaccuracies was indeed fixed by the consensus.
目次
Study Top quality
To look at methodological high quality and you may legitimacy away from results, an excellent 9-area crucial appraisal analysis equipment was developed based on earlier meta-analyses. Brand new programming requirements on quality rating of the many training fulfilling introduction criteria is placed in eTable 1 and you can eTable dos for the the Enhance. Stuff got a score out-of 0 (no) otherwise 1 (yes) per requirement and you may summed supply a whole score aside from nine. The new classification system utilized understood training off lower (?2), average (3-5), otherwise large (?6) quality.
Formula off Impact Systems
The study had been extracted and you can registered with the Comprehensive Meta-Data (CMA) application (type step 3; Biostat). Some meta-analyses were conducted for each sorts of sexting conclusion, demonstrated since a hateful prevalence, that have related 95% CIs in the estimateprehensive Meta-Analysis application transforms the new incidence speed for the a beneficial logit event rate effect proportions that have a computed fundamental mistake. Then, effect versions is actually weighted of the inverse of its difference, providing higher pounds so you’re able to education which have large test items for example even more accurate quotes. In the long run, logits is retransformed into proportions to facilitate ease of translation. Random-consequences habits was in fact selected in order to calculate impact sizes while they depict Chile mujeres en nosotros a conventional estimate of the suggest frequency.
Sensitivity Studies and you will Guide Prejudice
Inspection from container plots derived in SPSS (adaptation 23.0; IBM Company) was in fact examined, and you can sensed outliers had been taken from the brand new computation of the effect dimensions in the event the incidence rates was in fact influenced by these types of philosophy. Publication prejudice are checked out using assessment from harness plots of land as well as the Egger shot.
Assessment of Analytical Heterogeneity and you may Subgroups
The newest Q and i also dos statistics was basically determined to assess to possess analytical heterogeneity out of impact brands. A serious Q statistic means that investigation variability ultimately proportions estimates is greater than testing mistake, and you may moderators are going to be browsed. The new I 2 fact explores the rate off variability round the knowledge because of heterogeneity instead of possibility. The new I 2 fact selections out-of 0% so you can 100% and will feel translated as the zero (0%) and you may maximal (100%) heterogeneity. Between-data heterogeneity try looked at with the Q fact (categorical moderators) and you can meta-regressions.
Abilities
Since revealed regarding PRISMA flow diagram ( Figure step one ), all of our electronic browse produced 1147 nonduplicate details. All in all, 122 posts was recognized as possibly appointment addition conditions, and you may full-text stuff was retrieved. Toward post on all the complete-text message content, 41 knowledge fulfilled introduction criteria.
