During the evaluation period, the SWAN-OM was implemented for SSTs. A total of 120 practitioners from the web-based therapy service were recruited and trained to administer the SWAN-OM at
The SST intervention was delivered over a 40–60 min text-based chat in the online synchronous messaging system of the web-based service. The broad SST aims were to engage, conduct a brief assessment, and meet the needs of young people where possible. Brief risk assessments and safeguarding protocols were prioritized above those aims as part of service provision; these include a routine risk inquiry in every chat with questions to users explicitly asking about harm to themselves or others, and, if there is a disclosed risk, the single-session appeared will follow safety procedures as opposed to the SWAN-OM selected “Wants” and “Needs” and its processes. The approach of SST delivery by practitioners within the service was pluralistic (64 (link)) with a broad range of therapeutic orientations. The SST interventions delivered during the evaluation considered the brief-intervention mindset and its blend with traditional approaches to counseling (65 (link)), in addition to the already established evidence based on SST (13 (link), 18 (link), 66 (link)).
The SWAN-OM was administered when practitioners clicked a button in the platform to launch the questionnaires in the front-end view of the user. The battery of instruments was administered at the same points in time, before the chat (Time 1: pre-SST; PANAS and SWAN-OM) and after the chat (Time 2: post-SST; PANAS, YCIS, ESQ, and SWAN-OM).
Young people could skip the measures if they wished to at the time of accessing the service. The practitioner was able to access the item selection of the SWAN-OM at Time 1 and then start the SST when ready. Following the end of their SST chat with a practitioner, young people were asked to complete the post-session measures. Individuals who skipped the administration of the questionnaires at Time 1 were not presented with the other measures at Time 2.
