Mental disorder has its widespread presence and increasing around the globe at an alarming rate. In spite of the existence of effective psychotherapeutic strategies, a significant percentage of individuals do not get access to mental healthcare facilities. A handful amount of research has been conducted to facilitate the existing therapies more accessible via digitization. In this paper, we have proposed a digitized game that is able to magnify the impact of one of the strategies of Cognitive Behavioral Therapy (CBT). This can provide an opportunity for self assessment of individuals' emotional state and enhance impulsive dominance on positive thinking. We have developed a serious game Militant of the Maze (MoM), accessible via handheld devices (e.g. cell phone, tablet) that comprises strategies of CBT that emphasizes the consequence of 'alternation' to prevail over challenges of everyday life. We hypothesized that perseverance of the ability of 'alternation' can notably improve treating the patients dealing with Obsessive Compulsive Disorder (OCD). The experimental outcome demonstrated that the existence of 'alternation' in gameplay can significantly improve players' positive affect and decreases the negative affect, which can impact improving the efficacy of psychotherapeutic treatment by influencing players' mindset of opting for an alternative solution while confronting circumstances in everyday life.

With the advancement of technology, the handheld devices equipped with various sensors are playing vital role in video game sector. In serious games where the goal is beyond entertainment, handheld devices act as an expedient medium. The accessibility of gaming has been leveraged enhancing its scope of application in various sectors including mental health. Qualitative analysis of gameplay experience is key to perpetuate the standard of game. While it comes to serious games, the impact of gameplay experience may significantly vary depending on the personality of the player. In serious games, where the primary goal is people's cognitive, social, motivational, and emotional enhancement, analyzing this differential impact is crucial. In this paper, we have presented an analysis of the differential impact of personality traits in serious gaming context. To conduct the experiment we have adopted our previously developed game Militant of the Maze (MoM) that comprises one of the efficacious strategies of Cognitive Behavioral Therapy (CBT), Find alternative as underlying gameplay strategy, which is used to treat Obsessive Compulsive Disorder (OCD). After conducting a large-scale user experiment and statistical analysis we have demonstrated that individual PX can be significantly impacted by the player's personality trait in a serious gaming context, which may significantly impact the efficacy of the framework to treat people with OCD.
