to make use of, or to not use? That’s the query.


Set off warnings are used to assist people keep away from or emotionally put together for content material that will trigger them emotional or psychological misery (Cares et al., 2019; DeBonis, 2019; George & Hovey, 2020). Though well-intentioned, the proof base and particular person opinions in the direction of the advantages of set off warnings are blended.

Set off warnings can go by different names, akin to content material warnings, content material advisories, and content material notes, and are commonly utilized by TV and conventional media shops (Charles et al., 2022). Their more moderen adoption by on-line media channels and particular person content material creators has introduced into query their appropriateness, helpfulness, and in some instances, their potential for hurt.

Critics level to findings that recommend they introduce anticipatory anxiousness (Bellet et al., 2018; Gainsburg & Earl, 2018), undermine the resilience of content material customers and their capability to sit down with distressing data, and over-sensitise people to difficult, however essentially necessary, subjects (Lukianoff and Haidt 2015; Bellet et al. 2018).

Others argue that they supply people with a way of company and permit them to make lively selections about whether or not to have interaction with or keep away from, sure forms of content material (Cares et al. 2019; George and Hovey 2020; DeBonis 2019).

With restricted analysis, blended findings, huge particular person variability in views, and an absence of consensus for what constitutes set off warning and when it’s required, a current meta-analysis of the efficacy of set off warnings was a really welcome and well timed addition to this ongoing debate (Bridgland et al., 2023).

Variations in the way content warnings have been defined, measured, and implemented make it difficult to compare their efficacy.

Variations in the way in which content material warnings have been outlined, measured, and applied make it troublesome to check their efficacy.


Research investigating participant psychological or psychophysiological reactions or behaviours to set off warnings have been included on this meta-analysis. Set off warnings needed to particularly notify members that the content material they have been about to view could elicit recollections or feelings related to previous experiences. Set off warnings that have been common in nature (e.g., PG-13 warnings) have been excluded. Research additionally needed to measure outcomes regarding a number of of the next: response have an effect on, avoidance, anticipatory have an effect on, and academic outcomes (i.e., comprehension).

407 articles have been initially recognized as assembly the search standards. After eradicating 171 duplicate papers, 236 abstracts have been screened in opposition to the inclusion standards. Of those 236 abstracts, solely 20 research have been in a position to be included within the full-text screening.

The total-text screening recognized gaps inside a few of these research (i.e., offered warnings that didn’t meet the definition of a set off warning as outlined inside this overview, and didn’t measure the identical outcomes), leading to a complete of 12 research that may very well be included within the meta-analysis. Extracted psychological and behavioural outcomes have been then organised into 4 classes: anticipatory have an effect on; avoidance; comprehension and response have an effect on. A 3-level meta-analysis with nested results was then performed.


Every of the 12 included research have been printed after 2018. Most research used a single-session design the place members have been randomised to obtain a content material warning or a management situation. Nearly all of research additionally measured their major outcomes instantly after members have been uncovered to distressing content material or a content material warning (or each). The authors reported that included research have been predominantly performed in WEIRD societies (Western, Educated, Industrialised, Wealthy, and Developed) and thus lacked various cultural views. Most samples comprised trauma survivors: solely two impact sizes within the meta-analysis excluded trauma survivors, and a number of research solely examined trauma survivor experiences.

  • Eleven of the twelve included research have been unanimous of their conclusion that set off warnings didn’t have a significant influence on:
    • members’ emotional response to adverse materials (outlined as ‘response have an effect on’),
    • avoidance behaviours (with some research reporting that content material warnings fostered extra engagement, not much less) or
    • studying outcomes.
  • Outcomes additionally indicated that content material warnings persistently led to a quick improve in misery as a consequence of members anticipating distressing content material (outlined as ‘anticipatory anxiousness’).
  • Solely one of many twelve research avoided concluding that content material warnings are ineffective, and as an alternative highlighted that there are numerous competing advantages and threat elements which are troublesome to disentangle.

General, the outcomes of this overview don’t help that content material warnings are useful, and they don’t seem to help people in emotionally getting ready for, and avoiding, distressing content material. This raises questions on if, when, and the place content material warnings are most useful for various people.

Results suggest that content warnings are not as helpful as we think they are.

Outcomes recommend that content material warnings usually are not as useful as we predict they’re.


The findings from this meta-analysis present a compelling argument that set off warnings don’t meaningfully influence emotional response to distressing materials, behavioural avoidance, or understanding of the content material being seen. In truth, outcomes recommend that typically content material warnings improve anticipatory misery and end in a interval of discomfort previous to publicity.

Though it’s acknowledged that these findings have predominantly been drawn from western, non-clinical, grownup samples and can’t be generalised to all people, the outcomes increase quite a few necessary questions. Future areas of investigation ought to embrace the potential advantages of content material warnings for cohorts with particular trauma experiences; how tradition could affect the acceptability and influence of content material warnings; in addition to the differential impacts for particular teams akin to neurodiverse people and younger folks. Additional, the included research solely checked out instant, short-term reactions to warnings. Little is understood concerning the longer-term impacts and the way cumulative publicity to distressing content material (and in flip, content material warnings) impacts people.

From the current meta-analysis, it may be concluded that for predominantly white adults in western, developed nations, content material warnings serve little goal. Nevertheless, this can’t be the top of the dialog as a result of many extra people than have been represented on this meta-analysis are uncovered to distressing content material commonly.

Although content warnings do not appear to be helpful for white adults in Western, developed nations, future research must consider other groups of individuals who are exposed to distressing content regularly.

Future analysis should think about  the differential influence of content material warnings on people from black, ethnic, and indigenous backgrounds.

Strengths and limitations

This research was the primary meta-analysis of the psychological results of content material warnings. The authors word that earlier analysis findings have been blended, and due to this fact, there’s potential for proponents of both ‘aspect’ of the controversy to solely cite research that help their views. As suicide prevention researchers targeted on how younger folks use social media for suicide and self-harm associated communication, we argue that this meta-analysis is a vital scientific contribution to the literature, nonetheless, many questions stay unanswered with respect to the potential utility of content material warnings.

Entrance of thoughts is the truth that anecdotally, many younger folks have instructed us that they assume content material warnings are useful and they might desire content material warnings be used previous to being uncovered to self-harm and suicide-related content material on-line. On the one hand, this presents a difficult state of affairs the place the perceptions and preferences of younger persons are in battle with the proof on this overview. Nevertheless, you will need to word that the research included on this meta-analysis targeted on adults, and developmental variations could play an necessary position within the usefulness of content material warnings. In relation to on-line publicity, younger persons are amongst these more than likely to come back throughout distressing content material as a result of period of time they spend on-line, and the way in which present algorithms work on many well-liked platforms. As such, there’s an pressing want for future research to think about age-appropriate methods for giving younger folks the selection in regards to the kind of content material they have interaction with. Moreover, the character of this research meant that it didn’t embrace qualitative analysis into the views’ and views of younger folks. It’s attainable that social media customers could report experiencing content material warnings as qualitatively useful, even the place elevated anticipatory have an effect on and blended behavioural outcomes (e.g. avoidance or the ‘forbidden fruit’ impact) are recognized. In truth, anticipatory anxiousness could, at instances, serve an necessary goal. We argue that the views of social media customers, and notably younger folks, can be a vital addition to this dialog going ahead.

Subsequent, it’s vital that culturally and linguistically various communities are invited to contribute to analysis into the impacts and advantages of content material warnings. This can be a limitation to the prevailing physique of literature and thus the meta-analysis was not in a position to study the differential influence of content material warnings throughout cultural teams. For instance, in Australia we all know that warning viewers that they could be uncovered to details about somebody who has died is especially necessary for a lot of First Nations communities. For some Aboriginal and Torres Strait Islander Australians, being uncovered to photographs or names of people who’ve died can’t solely trigger misery however may violate strongly held cultural prohibitions (AIATSIS, 2022). This is only one instance of many nuanced and sophisticated concerns that needs to be made when contemplating the usage of content material warnings and the way their that means and worth could differ throughout cultures and communities.

Research needs to explore the impact of trigger warnings on children and young people, as developmental differences may influence their usefulness in engaging with online content.

Analysis must discover the influence of set off warnings on youngsters and younger folks, as developmental variations could affect their usefulness.

Implications for apply

General, we argue that the means distressing data is shared on-line is extra necessary than whether or not or not a content material warning is included. Content material warnings have the potential to turn into a ‘tick-box train’ and should disincentivise customers from sharing delicate data in secure methods. For instance, the #chatsafe pointers (the world’s first pointers developed to help younger folks to speak safely on-line about self-harm and suicide) encourage younger folks to pause earlier than posting and think about the knowledge they’re posting, and what the implications could also be for themselves sooner or later and people who they care about. #chatsafe additionally encourages younger folks to keep away from detailing strategies of self-harm and suicide (what, how, the place and when) and they’re inspired to observe this steering no matter whether or not a content material warning is used. The not too long ago up to date #chatsafe pointers step younger folks by means of share their tales of self-harm and suicide in secure and useful methods for themselves and their on-line mates (Robinson et al., 2023). Issues for the way details about different subjects will be shared safely would additionally contribute to safer on-line interactions, and scale back the duty positioned upon content material warnings to maintain everybody secure.

Findings of this meta-analysis additionally help the significance of discussing on-line content material in offline settings and in offering applicable help to people uncovered to dangerous materials. That is notably necessary for clinicians, or these working with younger folks, when contemplating and discussing the character and amount of distressing on-line content material younger persons are uncovered to each day.

Lastly, an necessary query stays regarding the language used when referring to set off warnings – ought to it’s content material warnings, content material discover, content material advisory or one other time period? Some argue that the time period ‘set off warning’ denotes that the knowledge being shared ought to be triggering or traumatic indirectly, and this will perpetuate already extremely stigmatised subjects. Totally different phrases are utilized in apply and all through the literature, and you will need to perceive the views of neighborhood members who such content material warnings are designed to help. The views of younger folks with lived expertise of trauma needs to be paramount on this dialog.

The findings of this paper have made an necessary contribution to what must be an ongoing dialog. Extra nuanced understandings of the place, when, and the way content material warnings help customers to make acutely aware choices in regards to the data they share and devour on-line will contribute to safer interactions and in the end guarantee the protection of each content material creators and customers.

 A much more nuanced understanding of where, when, and how content warnings support individuals is needed.

A way more nuanced understanding of the place, when, and the way content material warnings help people is required.
