The aim of the study is to evaluate the effectiveness of long-term and short-term app-based
self-guided psychological interventions to reduce craving and lapse risk in problematic
behaviors and substance use.
Two main self-guided intervention modules are available. Short-term self-guided intervention
module include mainly audio-guided sessions on gratitude, thoughts management, auto-empathy,
and relaxation. Moreover, there based on breath relaxation exercises, craving management, and
motivation to change Long-term self-guided intervention module include CBT-based
interventions, meditations, mindfulness, and journaling.
Participants are recruited via newsletters, local and nation-wide advertisements, as well as
through social media. The study is conducted via a mobile application "Nałogometr", freely
available to participants. We recruit people from the general population residing in Poland.
To compare the effectiveness of mobile app-based self-guided psychological interventions,
study participants are randomly assigned to either the intervention group or the control.
Experimental conditions are balanced based on multiple variables provided during onboarding:
(1) main addiction type; (2) participation in addiction-related therapy; (3) gender; (4) age;
(5) addiction severity; (6) abstinence duration.
Participants in the intervention group have access to short-term and long-term interventions,
whereas those in the control group only have access to the weekly ecological momentary
assessment reports. Participants in the intervention group will be able to access the
intervention materials 5 days after enrollment and will receive weekly ecological momentary
assessment reports. Those in the control group will be granted access to all intervention
materials after five weeks following study enrollment.
Questionnaire battery assessments will take place: (1) at baseline in the first week
following onboarding in; (2) after 5 weeks; (3) after six months. In addition, longitudinal
data on several variables related to craving and lapse risk will be collected daily using
ecological momentary assessment.
