Young people are increasingly turning to online support, especially when traditional mental health services are not immediately available. Using a cross-sectional design, sociodemographic information and self-reported perceptions of the strength of the working alliance and client satisfaction were collected from a sample of participants (n = 78) who were users of a service providing free online support using synchronous instant messaging. The results reported a significant positive relationship between the strength of the working alliance and client satisfaction, suggesting that the strength of the working alliance remains a key component in counselling, even online. Participants, however, scored significantly lower on both the strength of the working alliance and client satisfaction, compared to participants in offline settings as reported in past studies.
