Introduction
Mental health problems affect approximately one in six people in the United Kingdom. 1 The World Health Organisation recently identified insufficient supply of mental health services as a primary barrier to mental healthcare worldwide. 2 Against this backdrop, peer support online forums potentially offer an easily accessible and inexpensive alternative and/or additional type of support to professional support and face-to-face peer support groups. Many forums are available 24/7 and thus have the potential to deliver support at scale. 3 Indeed, there is evidence of a growing use of such forums.4,5
Marshall et al. 3 define ‘mental health peer support forums’ as ‘online, primarily asynchronous text-based discussion platforms’ that encompass ‘any forum primarily intended to support people experiencing psychological distress, including those with specific mental health difficulties, experiencing isolation, substance misuse or addiction, or caregiving for someone with a mental health difficulty’. Such online forums are perceived by many as providing convenient access to information and advice in a non-judgmental environment, where what is referred to as ‘lived experience’ can be shared for the benefit of others and oneself. 6 As such, they offer emotional support and may support patient autonomy by complementing the information provided by clinicians.7,8
Smailhodzic et al. 9 conducted a systematic literature review of the effects of social media use by patients for health-related reasons. They identify several types of use, such as seeking emotional support, information, and network support. These, in turn, may potentially lead to patients’ improved self-management and control as well as enhanced psychological and subjective well-being, but also diminished well-being and loss of privacy. The research also highlights that social media use can affect the patient–healthcare professional relationships and dynamics.
The role of informational and emotional support in online health communities has been analysed extensively, 10 showing that seeking information about a condition and treatment options may make patients better prepared for consultations with a medical professional.11,12 By sharing information and experience with peers who are well equipped to sympathise with their circumstances, patients may feel more informed and less lonely.13,14 Even passive participation, that is, not actively contributing and only reading others’ stories, may reduce anxiety. 15 Feeling more informed about their condition and learning about others’ coping strategies may also improve patients’ perceived control and ability to manage their condition. 15
The importance of the supportive role of social networks has been underscored in several research studies. Gruzd and Haythornthwaite 16 compared offline and online relationships and concluded that, generally, social bonds maintained online can be as supportive as face-to-face interactions. The networks can convey a sense of belonging, help combat loneliness and compensate for the lack of face-to-face social interactions. This applies particularly to networks of participants with shared attributes,17,18 as in the case of patients experiencing mental health challenges, who are more likely to share their health concerns with peers experiencing similar circumstances. 19
However, in spite of the increasing popularity of mental health forums, the impacts of participating in online mental health forums, including by sharing and receiving lived experience, are not fully understood, with concerns being raised particularly around their safety and effectiveness. In general, research suggests that internet users are not sufficiently equipped to assess the quality of information received through these channels. 20 Indeed, previous research has identified both positive and negative impacts. 9 On the one hand, online forums have also been shown reduce mental health-related issues such as social isolation, depression, and suicidal thoughts.21–23 On the other hand, they can aggravate other related issues such as suicidal ideation, negative body image, and disordered eating patterns.24,25 In order to make decisions about the use of forums in mental health support, therefore, there is a need to better understand how these impacts are generated, across different forums, and for different people.
Online participation in general is increasing and research topics reflect this change – recent research studies focus, for example, on technological affordances of online communities and how they can co-create value and provide access to support 26 or on specific at-risk subgroups, such as migrant communities. 27 Other recent studies have focused on advice-seeking, advice-giving, and advice-evaluation to determine which advice is deemed by the participants as helpful28–32; for example, Reuger et al. 28 show that speedy advice received from others, who have similar predominant interests, is valued most. Other studies 33 focus on evaluating the quality of information received in online forums, acknowledging the issues arising from the potential misinformation while also recognising that well-designed online communities ‘can be safeguards of high-quality information, but new models will need to be developed that will allow a higher level of integration of health professional moderators and the implementation of mechanisms to attenuate the sharing of low-quality information among users’ (p. 16).
Many studies have focused on the language used in the forums. For example, Sillence 10 highlights the role of narrative, as narratives or personal stories are one way in which people convey information about their health and well-being in the internet communities. Narrative is a form of social practice which captures habituality and regularity in discourse 34 and affords the opportunity to study how people make sense of their experiences. 35 Some studies focusing on narrative tend to treat the stories as an authentic window into a teller's experience,34,35 while potentially insufficiently considering that ‘language use can – and usually is – shaped by motivations other than simply being “transparent” or “authentic”’ (p.-34). Other research on narrative focuses, for example, on complexities of lay interpretation of expert discourse. 36
In addition to narrative, other examples of language-based approaches include LIWC (‘linguistic inquiry and word count’) methodology and some NLP (‘natural language processing’) techniques
37
(for extensive critical discussion of LIWC in the context of forum analysis, see Hunt and Brookes.
38
While NLP methods focus on the use of words in isolation, in this article we employ the methods of corpus-based discourse analysis, which involve the construction of large digitally searchable textual datasets (or ‘corpora’) and the combination of both quantitative and qualitative methods to the study of repeated linguistic patterns in their context of use. These methods have proved useful in several areas of health research, including, for example, cancer39–42 and end of life care.43,44 While one's experience sharing may linguistically take many forms, the present study focuses only on the use of the word
In addition, our study shows the potential of an interdisciplinary approach. Corpora consisting of forum posts, that is, non-elicited, spontaneously produced text, present the analyst with rather ‘messy’ data but are a useful complement to other approaches that investigate elicited responses, for example, surveys and interviews. This study is situated within the context of the Improving Peer Online Forums (iPOF) project, (https://www.lancaster.ac.uk/ipof/) which uses a transdisciplinary approach to understand the mechanisms underpinning the positive and negative impacts of online mental health communities, with the aim of co-designing good practice guidance and tools, with relevant stakeholders.
The objective of this article, therefore, is to answer the following research questions:
How do forum contributors use what they refer to as their own How do forum contributors react in their posts to what they describe as
Methods
Data: Forums used in this study
In this article, we analyse two corpora consisting of posts from two online peer support forums dedicated to mental health, which we will refer to as Starling and Magpie. Both forums have wide user communities but differ in other respects. Starling is a user-led forum on a commercial site open to everyone, with a broad thematic focus on mental health. It has non-professional volunteer moderators, who are active users of the community with their own lived experience. Magpie consists of a platform of multiple sub-forums for health-related discussions, which are typically created on behalf of predominantly voluntary, community and faith sector (VCFS) organisations. Our dataset includes a subset of four Magpie sub-forums; each focused on a specific mental health topic or condition. Magpie forums involve moderators who are trained by the organisations that created them. A more detailed description of each forum can be found at the iPOF project website (https://www.lancaster.ac.uk/health-and-medicine/research/spectrum/research/ipof/case-summaries/). The data includes posts made between 2016 and 2023, both from the forum users and their moderators; however, due to ethical concerns, we have, in this study, anonymised the data so that we cannot link the posts back to the individuals that posted them or distinguish between users and moderators. The total number of posts in the dataset is 146,388, which amounts to 14,621,374 words (Table 1).
Word and post counts in the datasets.
Ethical considerations
Ethical approval for the iPOF study was granted by the UK National Health Service (NHS) Solihull Research Ethics Committee (IRAS 314029). The study is sponsored by Lancaster University and hosted by Berkshire NHS Foundation Trust in the United Kingdom.
In analysing forum data, that is, posts by the forum users, there are numerous important ethical issues. 45 We have carefully considered the potential costs and benefits of carrying out this research, and worked closely with multiple stakeholders, legal and governance experts, and forum hosts, moderators and users to develop a comprehensive ethical framework which is available on the iPOF study website. (https://www.lancaster.ac.uk/health-and-medicine/research/spectrum/research/ipof/ethics-framework/) The wider objective of this article, to understand one of the ways in which lived experience is explicitly used on online forums, supports the overall goal of designing forums that better support their users’ needs. In doing so, we recognise the importance of ensuring forums remain a safe space to share information and that maintaining the anonymity of users is fundamental to this sense of safety.
The Starling forum is a publicly open forum with no expectation of privacy. In collaboration with the forum moderators, we posted about the study onto the forum, with a designated email inviting questions and debate. We gave users the option to email if they wanted their posts removed from the dataset. Users of Magpie are able to freely give consent at sign up (i.e. they can still use the forum without consenting for their data to be used). Consequently, in this study, we only used posts made by consenting users of Magpie.
All data from both forums was anonymised before being analysed, including removal of usernames, and place or person's names. De-identified data has been stored in a Secure Research Environment with restricted access and will not be shared as part of the Open Science Framework. Our de-identifying efforts further include pseudonymisation of the forum names (using bird names, i.e., Starling and Magpie in this study) and the modification of all examples quoted so that they cannot be linked directly back to the forum. Moderators have not been identified within the dataset as this increases the likelihood of identification; though their role is likely to be significant. 46
The study keyword: The word ‘experience’
Our study investigates experience sharing on mental health online forums by analysing posts that use the word
We initially considered including the term
But, from a linguistic point of view, the terms
In addition, in our data,
Corpus linguistic analysis typically starts from a keyword in context,
Top 15 collocates of the word
The list of the top collocates (Table 2) includes, in addition to ‘content’ words like
We therefore further extracted the collocates of the phrases
All instances of the three phrases were extracted from the data, resulting in:
307 instances of 362 instances of 272 instances of

In combination, the phrases
The coding scheme captures the two main types of linguistic behaviours that were found to occur in close proximity to the phrases
We operationalised ‘advice’ as the use of verbs in the imperative mode (e.g. (1) but We operationalised ‘information’ as statements concerning processes, events or facts that are based on the person's experience but are presented as potentially of more general applicability. In (2) below, the poster draws from their (2) Actually, medication can be useful in addressing various symptoms which arise from [NAME OF CONDITION] when it is not treated. This is something I’m taking
Based on our familiarity with the data, proximity was operationalised as two sentences on either side of the sentence in which the phrase occurs, to ensure that instances of advice/information were close enough in the post to the reference to the person's experience for us to reasonably assume that they were linked.
Each instance of advice or information was further coded for the topic(s) of the specific case of advice/information. The topic codes with examples are provided in Tables 3 and 4. The main topic codes (four for advice and five for information) capture the most frequent patterns in the data. The ‘other’ codes were applied to cases where the topic was not part of a larger pattern and/or not directly relevant to mental health. Each example could in principle be coded as including both advice and information, and receive up to three advice and/or information codes.

Overview of distribution
Figures 1 and 2 provide an overview of the different topic codes for information and advice, respectively. Among the advice codes (Figure 1), the most frequent are ‘Advice to seek help’ (39% of all advice codes) and ‘Advice on non-medical management of MH condition’ (30%). Among the information codes (Figure 2), the most frequent topic codes are ‘information about treatment and medication’ (31% of all information codes) and ‘information about a condition’ (26%).

Our findings with regard to the frequencies of different types of advice and information reveal several common patterns in our data whereby posters use their own experience, referred to as (3) Do try a therapist. It's necessary. (4) It's good to try and have 8 hours sleep too. A sleep routine has so much more to it […], how to react if you wake up in the small hours. But In addition, both advice and information are provided about how to engage with mental health services, and what to expect. Examples (5) and (6) exemplify, respectively, codes ‘advice about health professionals’ and ‘information about health professionals’. These two examples also point to two recurring themes: in example (5) the poster points to possible communication difficulties and how to deal with them, while in example (6), the poster highlights the long waiting times for NHS services. (5) If you discover that what they [psychologists and counsellors] are meaning doesn't make sense to you, please ask […] being honest with them is much better […] I know (6) You can find people to help out there, but
Among the information codes, perhaps as one might expect, the most frequent codes are ‘information about treatment and medication’ (example 7) and ‘information about a condition’ (example 8), in which posters share details related to their condition and how it has been dealt with.
(7) I’ve had three separate times taking […] I am just restarting them for the fourth time, now into week 2… I know (8)
Somewhat less frequent are the topics that were coded as ‘information about diagnostic process’ (example 9) and ‘information about non-medical management of MH condition (example 10).
(9) Even if you try something serious, (10)
Some posters make negative evaluations of mental health services especially in terms of long waiting times (see example (6) above) and sometimes advise others to opt for private providers as opposed to state-provided healthcare (e.g. ‘I would recommend […] going private and not bothering with the NHS at all’). However, our analysis of the use of
For both advice and information, a substantial proportion of codes focused on non-clinical help. These tend to be concerned with healthy lifestyles (see examples 4 and 10 above) but also very often with relationship management with family, friends and at work, as in example (11):
(11) That's something I’m going through right now and it isn't much fun.
Sharing your experience
Having looked at how experience is offered in the previous section, in this section we examine how posters respond to what they describe as
Distribution of impact and interactional codes across the dataset.
A breakdown of the above information by individual codes is provided in Figure 3, with the three codes we grouped under ‘impact’ at the top and the remaining interactional codes below.

Distribution of the impact and interactional codes across posts that include
The ‘expressing sympathy/concern’ code (example 12) and the ‘expressing empathy due to similar experiences’ code (example 13) occur, respectively, in 52% and 16% of posts that include (12) Thanks for (13) Thank you for
The interactional code ‘sharing more personal details about oneself’, which occurs in 69% of posts, typically captures cases where the poster discloses difficult experiences from their own lives as a result of reading similar experiences shared by someone else, as in example 14 (NB: This example was also coded for ‘expressing empathy due to similar experiences’):
(14) Thank you for
The code ‘asking for more details’, which occurs in 11% of posts, engages the addressee in further dialogue, as in example (15):
(15) I’m really considering again getting some private therapy in the meantime. Do you mind if I ask whether there's anything that you did differently, that you would say helped you to avoid […]? Thank you, really appreciate you
Among the ‘impact’ codes the most frequent is ‘feeling less alone/better/supported’, which occurs in 10% of posts. This applies to example (15) above, where the poster explicitly says: (16) I am so looking forward to the day my wife feels that joy and peace again. […] Everything that's happened has only made me love her more […] Thank you
The code ‘intending to take action’, which occurs in 5% of posts, typically applies to cases where the poster states that, as a result of reading someone else's experience, they will seek help or resume medication, as in (17) Thanks so much for
As example (16) shows, such reactions may also occur in posts by family members, who equally express gratitude to the posters who shared their experiences. Example (17) additionally highlights the value of the pool of shared experience, as in:
Discussion
Earlier studies,9–15 using different methodologies and approaches, show that participating in online communities, seeking emotional support, information and peer network, may potentially lead to improved self-management and enhanced subjective psychological well-being, and better prepare patients for consultation with medical professionals. The findings of our study further support, contextualise and expand these earlier findings.
Our analysis of the use of
In addition to lay advice and information exchange, the online conversations have been found to often be affectionate and emotionally supportive, which may be in contrast to time limited encounters with busy healthcare professionals.
51
Our quantitative and qualitative findings confirm that, when posters employ the phrases (18) Hi X Thanks for (19) Thanks for
Moreover, while we found instances of, for example, blanket negative judgements about health professionals, we did not find any clearcut instances of what we would describe as mis/disinformation or potentially harmful advice. It is not possible from the data available to know whether such posts are not being produced, or have been edited out as part of the moderation process. Other studies of peer online interactions have identified levels of information inaccuracy or information not fitting the needs of the patients.29,52,53
Our linguistic approach has also shown that, while drawing from one's experience to dispense advice and/or helpful information involves claiming some degree of authority for oneself, some posters use explicit disclaimers to indicate that their own experience may not be applicable to everyone else and/or cannot substitute professional opinion. In both examples (20) and (21), for example, the posters emphasise that they are speaking (20) I can't speak from the point of view of a doctor so can (21) Unfortunately, it's not possible for me to comment on the particularities of your case as I don't know. The information that I can share is
This suggests, in line with findings from other studies, 54 that online communities may develop self-regulated practices that improve the quality of the information peer exchange.
With regard to the use of
As with
By introducing a complementary methodology for the study of spontaneous online conversations, we have also shown the value of interdisciplinary approaches. Through the construction of a highly relevant, clearly delimited, dataset, based on one salient keyword (
Our study was, however, limited both in scope and sample size. In addition, the anonymisation of the data did not make it possible to distinguish systematically between posters and moderators, and posters with different degrees of involvement in the online community. Some earlier studies suggest that some online communities tend to have core groups of a limited number of users that provide most of the information and advice to more peripheral participants. 56 Some of the specialised sub-forums in Magpie in our data suggest similar behaviour that invites further investigation. Similarly, earlier studies show that the process of sharing information and advice online varies across different social networks, with some of the online platforms being more informative and others containing more messages of social and emotional support.10,57 These differences may be due to the nature of the health condition, the gender of the contributors, 58 or the underlying ethos of the community. 10 While this was not the focus of our study, we have come across similar patterns of behaviour, pointing to further potential areas of research interest.
While our results highlight the importance of the forums in creating a safe space for sharing information and advice about managing mental health challenges and navigating health services, based on lived experience, they also suggest that forums are perceived primarily as supplements to traditional care, especially vis a vis long waiting times for face-to-face care, rather than as an alternative.
Conclusion
Peer online forums dedicated to mental health are increasingly being described and used alongside or as an alternative to mental health services, in the United Kingdom and around the world. Such forums are often described as valuable because they provide opportunities for lived
Our analysis of real-world forum posts offers a way to see directly how sharing of lived experience works in online forums without being filtered through the reflections of the participants, or the social desirability and demand characteristics of surveys or interviews. Great care was taken to do this within an ethical framework that ensured users would remain anonymous. However, the analysis was limited to posts from only two of the seven forums collaborating on the iPOF project, and only on a selection of explicit references to
Peer online forums offer a free, widely accessible space for people to access support through the sharing of lived experience by people who are facing similar health challenges. Whilst highlighting some of the difficulties in accessing routine offline mental health services, the information and advice are generally in favour of engagement with services, suggesting that forums could offer a gateway into services, or a useful adjunct to other forms of support, and potentially help to alleviate distress for those on long waiting lists. Further research is needed to test the generalisability of these findings to other forums for mental health, and for other health conditions. More work is also needed to understand the range of impacts of using peer online forums on users, and their use of other services. This could inform policy and commissioning decisions around the role online forums should play in health service delivery.
Lived experience commentary by J. S. and Neil Caton
The use of lived experience within mental health forums has the potential to play a key role in a range of different outcomes for both forum contributors and forum readers. As a moderator, aiming to ensure that forum contributors speak from their own lived experience has been crucial. It creates a space for a broader range of experiences to be shared, accepted, and interacted with which has helped in facilitating many of the positive impacts which have been highlighted in this research.
However, it has also been highlighted that the available data limits the ability of knowing whether some instances of negative blanket statements or misinformation are not being made or have been amended by moderators. Given that the forums chosen had active moderation, how might this compare with forums that did not? This is an area which could be important to explore further, particularly in relation to the potential impacts of different moderating styles and/or rules on forum contributors, readers, and perhaps on moderators themselves. It is also worth exploring whether and to what degree forum contributors might feel able to speak from their own lived experience on different forums and under different styles of moderation. Factors such as certain topics or keywords being banned or the potential for bias when applying forum rules could lead to a range of impacts on sharing lived experience.
Overall, it is reassuring that this research highlights how valuable it can be to share lived experiences within mental health forums. Further research in this area has the potential to lead to positive changes in how moderators accommodate lived experience. It also has the potential to lead to more collaboration with external service providers. It will be interesting to see how further research evolves and influences change in ways which provide hope whilst remaining cautious of ongoing risks and suitability.
