Think Life, an Online Self-help Intervention for Coping With Suicidal Ideation

The intervention was originally developed by van Spijker, van Straten, and Kerkhof (2010). For this study, it was adapted to the Flemish context and called Think Life. Think Life is mainly based Cognitive Behaviour Therapy (CBT). Additionally, it encompasses elements from Dialectical Behaviour Therapy (DBT), Problem Solving Therapy (PST), and Mindfulness Based Cognitive Therapy (MBCT). It encompasses six modules and every module starts with a psycho-educational section followed by a weekly assignment, core exercises and optional exercises. The participant weekly receives access to a new module. A more detailed description of the intervention is described elsewhere (Kerkhof, van Spijker, \& Mokkenstorm, 2013; van Spijker et al., 2010; van Spijker, van Straten, et al., 2014).
