This manuscript aims to present a novel behavioral impulsivity test ImGo, which is suitable for impulsivity assessment in the general population. A series of three studies was conducted to validate its psychometric qualities. In Study 1 we describe the principles of ImGo and verify its test-retest and split-half reliability and its convergent validity with an impulsivity self-report scale and Stop Signal test. In Study 2 we re-analyze the convergent validity of ImGo with a Stop Signal test and examine the potential relationship between ImGo and oculomotor inhibition measured by an Anti-Saccades test. In Study 3 we present a robust research with a large sample size and investigate the discriminant validity of ImGo with tests of other related cognitive and executive processes. Backed by our findings from these studies we can safely claim ImGo is a powerful tool with a good level of reliability (both test-retest and split-half) and validity (convergent and discriminant). Its potential lies in its use in diagnostic and research practice of experts from various countries as the test has already been translated to 9 languages so far. The open-source Hypothesis platform, on which the ImGo test is running, provides the option of both individual and group testing in laboratory conditions as well as remotely through an internet browser.

OBJECTIVE: Although psychological treatments for patients suffering from medically unexplained physical symptoms (MUPS) show promising results, evidence for their effectiveness is still limited. The aim of this study was to review the existing empirical support for change mechanisms that explain treatment effect in terms of symptom intensity and symptom interference in the daily lives of patients. METHODS: A systematic database search was conducted. Sixty-seven eligible studies were found, and change mechanism effects were extracted from them. The data were subjected to a systematic review. RESULTS: Fifteen change mechanisms were identified. Those receiving the most consistent support included Increasing symptom acceptance, Development of coping strategies, and Positive treatment expectations, although the last mechanism was investigated in only two studies. Almost all mechanisms received support for at least one type of outcome, either at post-treatment or at follow-up. CONCLUSIONS: Although some empirical support exists for many mechanisms, some of them have received only marginal attention in empirical studies. These limitations prevented us from deriving more definite conclusions.
