This study aimed to employ the theory of change approach to integrate digitalised lived experiences (DLEs) from THA into Friendship Bench, a CBT-based psychological intervention. Using ToC, we aimed to develop a pathway for integrating DLEs through consensus building with key stakeholders. The ToC also defined the outcomes that can be expected from the introduction of DLEs into therapy. On integration, findings from the ToC indicated that the digital stories from THA could be best utilized as homework that can be shared with clients to watch in their spare time. It was agreed the videos could help increase mental health awareness, improve mental health literacy, and reduce mental health-related stigma. Moreover, by listening to the stories of others who have gone through similar struggles it was hypothesized that listeners could learn, be inspired, and gain a sense of hope which would positively contribute to their subjective psychological wellbeing.
To our knowledge, this is the first time the theory of change approach has been applied to integrate DLEs with an evidence-based psychological intervention for treating CMDs. However, it is not the first time a participatory method has been used to develop a psychological intervention that makes use of digital stories to promote recovery (6, 19). The SMART program was developed through participatory workshops with people with lived experiences of psychosis and mental health practitioners (6). Similar, to the current study, findings from the SMART program also showed that the digital videos could be used as homework commonly referred to in therapy as a between-session intervention (26). However, the SMART program also made use of the videos in-session where they watched the video together with a health worker. Research shows that between-session interventions make therapy ubiquitous beyond therapy sessions with the therapist thus reducing the potential for therapeutic drift between the patient and the counsellor (27). Participants from the SMART program reported that watching the videos alongside a counsellor provided them with more support and motivation to watch than they would have had they watched alone (9). In terms of intervention engagement, the SMART program reported moderate use of the videos between sessions compared to in-session [56.7% versus 76.7%] (6). The moderate use of the website between sessions was attributed to lower levels of use of digital technology and higher rates of disability among persons with severe mental illness which may act as a barrier to non-supported access and use of the online resources (6). To remedy this the authors recommended employing a blended approach of offering both the in-session and between-session options to clients as a way to boost engagement with the intervention similar to how our ToC proposes(6, 8).
Findings from the current study indicate that introducing DLEs to the Friendship Bench model can potentially promote mental health awareness and increase mental health literacy among Friendship Bench service users as they learn from others. This is largely premised on the social learning theory which states that people can learn from others through observation, socialising, modelling, and imitation (28). Qualitative findings from the SMART study on digital stories showed the same as participants from the study reported gaining knowledge from listening to others as well as solidifying the knowledge they already have (9). The acquisition of knowledge and skills was described in a scoping review as improving a person’s sense of connection to others, self-efficacy, confidence and sense of personal achievement, factors which are considered essential in recovery-oriented service provision (1). Findings from our ToC also hypothesise that improved mental health awareness and literacy could also contribute to the reduction of stigma as a corollary outcome, especially self-stigma. Self-stigma refers to negative stereotypes that an individual adopts and internalises about their mental illness (29). These stereotypes may include a sense of insufficiency to carry social roles, feeling fundamentally different from others, and expecting pessimistic long-term outcomes (3, 30). Contact with other people with CMDs has been reported to reduce negative stereotypes in those also experiencing CMDs (6, 31). Thomas et al (6) found that video-based lived experience narratives had a moderate to large effect on the alienation subscale of the Internalized Stigma of Mental Illness Scale (ISMI) that was statistically different [p-value 0.006; d 0.69]. However, the effect on other factors, such as negative stereotype endorsement was low (6).
Regarding treatment outcomes, the current ToC indicated that the digital stories from THA could contribute to the reduction of CMD-related symptoms albeit as a distal outcome improved mental health literacy and coping. However, current literature is still inconclusive as to whether the use of digital stories can contribute to treatment outcomes due to the small sample sizes that previous studies have used which limit the generalizability of the findings (4, 8). Pre- and post-intervention data on outcome measures for participants from the SMART project pilot showed no significant changes in the primary outcome measure of personal recovery [F1,22=.140, p = .711, partial η2 = .006] (8). The study did not find any effect on depression and anxiety. On the other hand, results from two studies reported in a recent systematic review indicate that digital stories had a significant impact on reducing depression symptoms. However, it is important to note the participants from the study were elderly people with dementia and Latina women (P < 0.001) thus making it hard to generalise the findings across other settings and populations (4). The study on Latina women also showed a significant decrease in anxiety levels from a mean of 13.9 to 9.5 (F1,17=25.5, P < .001) at 1 week and 8.6 (F1,27=23, P < .001) at 6 weeks. However, this study lacked a control group to compare means with (4).
Qualitative data, however, indicates that listening to digital lived experiences could facilitate recovery in people with CMDs (1, 6, 8, 9). Listening to the stories of others was reported to improve client-counsellor interactions as using the videos enabled clients to express things they had not been able to before (6, 8). Other participants reported feeling connected to their peers in the videos and inspired by their recovery stories thus making them believe that their recovery was possible and strengthening their resolve (9). Participants also reported watching the videos of others made them feel less alone. Similarly, quantitative findings from the SMART pilot study showed significant reductions in loneliness with a large effect size [F1,22=5.878, p = .024, partial η2 = .211] (8). Substantial evidence supports the correlation between loneliness and common mental disorders (32, 33) and how loneliness is a common occurrence in people with CMDs (34). However, a major strength of the current ToC is that the integration is happening with an evidence-based intervention (i.e. Friendship Bench) that has proven effective in treating mild to moderate CMDs like depression (adjusted mean difference, − 6.36; 95% CI, − 6.45 to − 5.27; P < .001) and anxiety (adjusted mean difference, − 5.73; 95% CI, − 6.61 to − 4.85; P < .001) (15). Therefore, the counselling component of the intervention would focus on the CMD therapeutic outcomes and the digital stories on outcomes related to mental health literacy, stigma and the therapeutic relationship with the counsellor. However, as part of future research, it would be worthwhile to investigate the added benefit of the videos in reducing CMD symptoms through a randomised control trial that is powered enough to determine the effects of the videos conclusively.
Our ToC also noted some potential barriers that could get in the way of optimal integration however the one that stood out the most was the costs associated with accessing online content. A survey by Afrobarometer showed that whilst most Zimbabweans have cell phones 43% are said to have internet access capabilities. Around 25% were reported to be using the internet regularly while 62% reported never using the internet (35). Moreover, rural areas were found to be disproportionately affected compared to the urban areas with regards to the number of devices that have internet access capabilities [64%, vs. 28%] and this was attributed to the lack of internet infrastructure in rural areas (35, 36). Limited access to the internet would affect the uptake of the DLEs as they can only be accessed via the internet at the moment. Efforts are underway to mitigate the perceived accessibility challenges, and these include procuring mobile tablets for counsellors to share with those without devices and storing the video files directly in the counsellor tablets to share via applications like Bluetooth. For the long term, there are plans to develop a THA application that has the capability of accessing content offline like the YouTube application. Moreover, given that rural Zimbabwe is disproportionately affected by limited access to the internet and has fewer smart devices compared to urban it was agreed that in the meantime the intervention be implemented in urban settings and then scaled up as internet accessibility and use improve in Zimbabwe’s rural settings.
Limitations
A limitation of our ToC is that the integration framework did not go through feasibility testing as recommended by Breuer et al., (21) to evaluate the integration strategies that were developed during the ToC workshops. However, as highlighted in the ToC map [figure 1] that shall be the focus of our future research. As part of the study, we will evaluate the intervention's feasibility and acceptability. In the feasibility study, the current ToC shall be used to guide the evaluation of the intervention strategies and hypotheses related to the predicted outcomes and impact of the blended intervention. The findings will be used to improve the quality of the proposed ToC. Finally with existing literature being inconclusive on the impact of digital stories on CMD symptoms, it would be worthwhile to conduct clinical trials in the future that are powered enough to draw significant conclusions from and finally set the matter to rest. The research could further explore the method of delivery that yields the most benefits between in-session and between-session, and thus make a conscious effort to spread and scale up the desired mechanism of delivery.
