Effects of media stories of hope and recovery on suicidal ideation and help-seeking attitudes and intentions: systematic review and meta-analysis

Abstract

Summary: Background: There is strong evidence that suicides increase after media stories about suicides by celebrities, particularly those that highlight the suicide method (the Werther effect). Much less is known about the Papageno effect—the protective effects of media stories of hope and recovery from suicidal crises. A synthesis of the retrievable evidence is lacking. We aim to summarise findings from randomised controlled trials about the effects of stories of hope and recovery on individuals with some degree of vulnerability to suicide. Methods: For this systematic review and individual participant data meta-analysis, we searched PubMed (including MEDLINE), Scopus, Embase, PsycInfo, Web of Science, and Google Scholar published from inception to Sept 6, 2021, without language restrictions. We included trials that reported suicidal ideation (the primary outcome) or help-seeking attitudes or intentions (the secondary outcome) and tested a media narrative of hope and recovery. Studies were excluded if they did not feature a clearly positive story of hope and recovery, or had a control group exposed to suicide-related stimulus material. We contacted the lead or senior authors of all original studies to obtain participant-level data for this study. The primary analysis was restricted to individuals with some vulnerability to suicide. Risk of bias was assessed using the Cochrane risk-of-bias tool for randomised trials. The study is registered with PROSPERO, number CRD42020221341. Findings: Our search yielded 7347 records. 3920 records were screened by title and abstract, and 25 full-text records assessed for eligibility. There were eight eligible studies with 2350 participants for which individual participant data were sought. For suicidal ideation, six studies met the inclusion criteria for the primary analysis. Follow-up responses were available for 569 (90%) of 633 participants who were randomised with high vulnerability (345 [55%] allocated to the intervention group and 288 [45%] to the control group). The pooled standardised mean difference (SMD) indicated a small reduction in suicidal ideation of –0·22 (95% CI –0·39 to –0·04, p=0·017; six studies) in the intervention group. For help-seeking attitudes and intentions, four studies met the inclusion criteria and follow-up data were available for 362 (86%) of 420 participants (247 [59%] allocated to the intervention group and 173 [41%] to the control group). The pooled SMD showed no evidence of a difference between the groups (SMD=0·14, 95% CI –0·15 to 0·43, p=0·35; four studies). Low levels of cross-study heterogeneity effects were observed for both analyses (I2=5% [suicidal ideation] and I2=36% [help-seeking attitudes and intentions]). We found no evidence of publication bias. Interpretation: Media narratives of hope and recovery from suicidal crises appear to have a beneficial effect on suicidal ideation in individuals with some vulnerability, but there is insufficient evidence regarding help-seeking attitudes and intentions. These findings provide new evidence about narratives for suicide prevention. Funding: None.
