Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Relevant for this Paper:
This investigation aims to evaluate the stability of the effectiveness of different two-week online interventions in a four months follow-up regarding reward sensitivity, anhedonia and depression.
The authors will further investigate factors influencing treatment success regarding reward sensitivity. The investigators assume that the more depressive expectations and stress improve during our online intervention, the more change in reward insensitivity is experienced at follow-up. In addition, it is hypothesized that the more people engaged in physical activities and social encounters during the two-week online intervention, the more change in reward insensitivity is experienced at follow-up.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
A possible maintaining role in depressive symptoms plays reward hyposensitivity. Therefore, treatments should include evidence-based psychological interventions that target and modify reward insensitivity. Prior research lacks studies investigating reward sensitivity as main outcome measure, especially in the web-based format. This is why this study investigated an online intervention with the following groups regarding effectively increasing reward sensitivity compared to a waitlist control condition:
a) mindfulness-based interventions, b) behavioral activation, c) a combination of both.
The daily exercises were supported via videos and worksheets. Here, the investigators explore the effects after a four-months follow-up. In addition, this paper will deal with the long-term prediction of reward sensitivity, a feature not considered in our main paper preregistered with the ID NCT05402150. Factors, which are considered to play a big role in reward sensitivity are perceived stress, depressive expectations, physical activity and the frequency of social encounters.

Behavioral Activation
\- instruction to create a list of individual positive activities. - instruction to include daily positive activities and fill out a mood protocol, which covers the time period shortly before, during and after the activity.
Mindfulness and Gratitude

Mindfulness and Gratitude
\- instruction to fill out a mindfulness diary: reflection of daily pleasant situation, instructing the participants to revisit the impressions of their 5 senses during this situation, in addition they should specify how long they have actually dealt with
Combination: Behavioral Activation and Mindfulness and Gratitude
14 days of daily excercises
Combination of Behavioral Activation and Mindfulness and Gratitude
This group will do a combination of the two intervention types.
Waitlist control group
Will receive the intervention (combination) after two weeks of intervention time of the other groups.
