The development of a core outcome set for crisis helplines: A three-panel Delphi study

Abstract

Background

Evidence for the effectiveness of crisis helplines is limited by inappropriate and inconsistent outcome measurement. The aim of this study was to develop a core outcome set that reflects the most relevant and important outcomes to help-seekers accessing a crisis helpline via any delivery mode (e.g., phone, SMS text, online chat).

Method

We used a three-panel Delphi method to compare and integrate the views of three expert groups: people with lived experience of accessing crisis helplines (n = 32), researchers with experience assessing crisis helpline outcomes (n = 25), and crisis helpline supporters (n = 58). Across two online survey rounds (89 % retention rate), participants rated the importance of 33 potential outcomes for help-seekers accessing a crisis helpline. Participants also provided open-text comments and suggestions. Outcomes that reached consensus (≥75 % agreement) by at least two panels were included in the core outcome set.

Results

Ten outcomes met the criteria for inclusion in the core outcome set. In order of importance, these were: distress, feeling heard, suicide risk, connectedness/support, hopelessness, overwhelm, non-suicidal self-injury risk, service experience, helplessness, and next steps.

Limitations

Participants self-selected and were mainly from English-speaking countries.

Conclusions

We recommend future outcome and evaluation studies minimally measure and report the 10 outcomes identified in this study. Assessing an agreed set of meaningful outcomes will improve comparability and facilitate a deeper understanding of crisis helpline effectiveness. More work is needed to determine how best to assess these outcomes in the crisis helpline context.
