Hope is caused by our expectations that something good can happen - when we see a chance or option for good/rewarding (joyful, liked) outcome. (i.e. chance to meet someone you like)
Hope is linked to the activation in motivational D1 loop of ventral striatum. If output of this D1 loop is suppressed by lack of dopamine in brain, or by too strong output of D2 loop of ventral striatum, the hope, drive and motivation to move, go and act for your goals is inhibited.
Hello, please have a look at the work of the authors below; they operationalize hope as an emotion and link it to behaviors aimed at conflict resolution.
Hope(lessness) and collective (in)action in intractable intergroup conflict

ABSTRACT Intractable intergroup conflict is an extremely severe, violent and protracted form of intergroup conflict (Bar-Tal, 2013; Coleman, 2003; Kriesberg, 1993). Such conflicts include a number of unique characteristics that set them apart from other types of intergroup conflicts. One of these characteristics is the perception of irresolvability, which is closely associated with the feeling and development of hopelessness. According to the seminal work of Daniel Bar-Tal (1990, 2007, 2013), the lack of hope and the belief that the conflict cannot be resolved becomes, over time, an inherent part of the so-called Ethos of Conflict and thus helps to perpetuate intractable conflict by inducing indifference and inaction. Hope, on the other hand, has been suggested as an important emotion within conflict resolution (Bar-Tal, 2001; Jarymowicz & Bar-Tal, 2006) because it induces constructive and goal-directed behaviour (Stotland, 1969). We suggest in this chapter that one such behavioural manifestation of hope may be action to achieve social change, or in this context, collective action to achieve conflict resolution (which is a specific form of social change).
I use in depth qualitative research to capture 'intangible' goods. Hope, or its lack, for example, can be captured by questions on how people see their future, on their attitudes to society, on changes they would like to see which could improve their lives or that of their communities, but also more generally, through asking people to recount stories of their everyday lives and experiences.

You have some interesting works with hope as a dimension of psychological capital, but here, instead of an emotion, hope is conceptualized as a positive motivational state comprising positive feelings of agency and pathways to achieve the goals in question. You have a psychological capital scale (PsyCap) with good reliability.
I don't know about 'capturing' exactly but I use filmmaking as a research methodology to explore intangible goods... it attempts to connect the emotions of the participants with the emotions contained/manipulated throught the process of editing and then watching films. Will have an article in Area that discusses the project early 2015 and have more details on my academia.edu page as only just joined ResearchGate.
And I also think most of the research will be found in advertising - but here the purpose is always to persuade.
Hope is a very complex concept. One person's hope is another's hopelessness even when both are experiencing the same conditions. And you can be hopeful today and hopeless tomorrow depending on your circumstances and character. Thanks for the reference Ritesh.
