The aim of this study was to examine the validity and the reliability of the Turkish version of ADHD DSM scale. ADHD DSM Scale was applied in a sample of 225 persons. Simultaneously Attention Deficit Hyperactivity Disorder Self-report Scale (ASRS) scale was also applied and DİVA interview was used to ascertain the diagnosis in 45 indiviuals with suspected ADHD. The reliability, concurrrent validity and construct validity which is detected by factor analysis was found to be adequate. The Turkish Version of ADHD DSM Scale is a reliable and valid tool for scanning ADHD symptoms in adults.

Fear of Missing Out (FOMO) is an emerging concept related to internet and social media usage. FOMO is described as feelinganxiety when the person does not use social media. Studies showed that FOMO affects well-being negatively. In this study, weaimed to build a Turkish scale for measuring FOMO. For this, 31 items were prepared and in the final scale 22 items were retained.The reliability and validity measures were found to be adequate. For the future studies, we recommend to test the scale also withthe adolescent population and to explore the relationship between FOMO and well-being.

Flow state emerges when a person engages in autotelic activities, which are both enjoyable and challenging. While studies generally focused on qualitative data of flow state, a few were conducted on psychophysiological basis of it. Present study aimed to investigate EEG correlates of flow. Twenty participants preliminarily filled out Flow Short Scale Turkish Version and completed a ping-pong game at two levels (slow-boring and fast-flow) during EEG recording. The results revealed that theta power was significantly greater for all regions during flow condition compared to non-flow condition and delta power was significantly greater during flow on central and parietal regions. There is no difference between flow/non-flow conditions for coherence. A positive correlation was found between delta and theta powers and subscales scores of Flow Short Scale. The increases in these theta and delta frequency bands could be important indicators of flow state. The coherence results revealed that interhemispheric synchronization was not modified by flow. If confirmed with multiple tasks and in clinical groups, EEG correlates of flow state could be useful increase performance and well-being.

Sufi meditation is a spiritual form of physically active meditation in which performers (Semazens) whirl without losing conscious awareness and while internally focusing on reaching an ecstatic state, thus requiring substantial motor and cognitive control and monitoring. Studies have argued that the experience of the meditator may affect the strength of the brain activations because more experienced meditators may need less cognitive effort to reach the ecstatic state. Despite this, our knowledge about the associations between emotional states of the meditators and activated brain areas during meditation remains unknown. With this in mind, fourteen male Semazens were recruited for this study. All Semazens performed Sema meditation under the scanner using imagined whirling techniques. An active control condition was used to explore brain areas specific to Sema meditation. Measures of affective states and psychiatric symptoms were also collected. Statistical parametric maps were created to compare the meditation vs. control conditions. Accordingly, Sema meditation specifically evoked activations in left anterior cingulate cortex (ACC) and left orbitofrontal areas. Activations in ACC were negatively correlated with the positive affect of the Semazens suggesting that less cognitive effort required to reach the meditative state in Semazens was associated with more positive affect. Despite previous studies highlighting the experience of the meditators as a predictor of brain activation, we found that affective state may also be an important factor that may facilitate emotion regulation and cognitive monitoring in the brain. Our findings may also be applicable to the effects of meditation on psychological and emotional wellbeing.
